Chapter 696: Sword Forging Preparation
Early in the morning, Chu Fei participated in a discussion meeting at the Pharmaceutical Research Center.

Last night, the news that the elites of the Wei family, the Huang family and other families retreated, taking away more than 2,000 troops, had spread.

There was no way. There were no soldiers to be seen along a three-kilometer-long city wall near the west gate, and the open city gate was too conspicuous.

However, the efficiency in one night was also thanks to the advance preparation of the Self-Help Association. This was not ordered by Chu Fei, but planned by the Self-Help Association itself.

It should be said that the current self-help association is already a mature organization and does not really need Chu Fei's continued help.

It can even be said that the elites from the Wei family, the Huang family and other families who left Qingshi City this time will gradually be assimilated into the Self-Rescue Association.

After all, without leaving Qingshi City and Hongsong City, elites such as the Wei family and the Huang family also lost their foothold.

When we reach the new high wall, the only way for everyone to survive is to stick together for warmth.

At this time, at a meeting at the Pharmaceutical Research Center, Li Wenhui leaned back in his chair, carefully avoiding the wound on his chest. Seeing that Chu Fei and Ren Qingyun had recovered, he couldn't help but sigh, "At that time, I felt that the reflection spell took up too much computing power, so I didn't learn it. After I recover this time, I must learn the reflection spell."

Chu Fei didn't say anything, just sat there quietly.

The others didn't say anything, and everyone had a very heavy expression.

Li Wenhui chuckled and said, "Don't be like this, everyone. Although we have suffered a lot of losses, think about it on the bright side. We have survived another disaster and now have a good reason to withdraw.

I think now even if we leave here, no one will say anything.”

"Leave here?" Ren Qingyun muttered, then turned to look at Chu Fei, "Chu Fei, what do you say?"

Chu Fei nodded: "You can leave. But before you leave, please release a lot of videos of medicines below 10.0."

Ren Qingyun nodded, "Last night, all the information below 10.0 has been sorted out. There are more than types of medicines released to the public, covering all commonly used medicines, including the medicinal materials used to refine these medicines.

So far, more than 2,000 memory cards have been copied. There are no more. There are not enough memory cards.”

Chu Fei smiled, "We can allow downloading. We can sell it while allowing downloading. We are about to overturn the table anyway, so we can do it as quickly as possible."

Ren Qingyun nodded, "Then where do you think we should evacuate to?"

Chu Fei: "I think we have to retreat to Yumen City at least. Yumen City is adjacent to the jurisdiction of Lieyanlu City. If there is a chance, we can definitely enter the jurisdiction of Lieyanlu City.

I think that although Flame City is hostile to Thunder City, it is still very welcoming to pharmacists.

Even because the Flame Land City is plotting to take over the Thunder Land City, everyone might be given extraordinary treatment.

You can develop within the scope of the Fiery Land City for a period of time and see if there is a chance to enter the ruling scope of other land cities.

Anyway, we have made enough contributions to Thunder City."

Ren Qingyun nodded again, and then couldn't help but sigh.

Although Ren Qingyun didn't say anything, everyone knew that the turmoil had directly caused the cohesion of Qingshi City to collapse.

The so-called "when the tree falls, the monkeys scatter" is just like this. The most important thing is that the big tree of Thunder Land City is rotten from the inside.

Everyone knew that there was an insider involved in this assassination, and it was most likely related to Chu Fei and the Pharmacy Trading Center's strategy - affecting other people's money-making.

Since it affects your ability to make money, why don’t we just leave?
It is better to move the dead tree and the living person, so as not to stay here and pay for other people's mistakes.

After a discussion, everyone decided to leave. But before leaving, they had to add fuel to the fire to justify their anger.

In the morning, a practitioner came to the Pharmaceutical Trading Center... no... it was the Pharmaceutical Research Center, but was immediately attracted by the roll-up banner at the door.

The roll-up banner reads:

[Today, the Pharmaceutical Research Center will announce three things involving three major actions.

The first thing, which was also the first major action, was to release the battle video of Chu Fei and Liu Jinhui at 9 o'clock.

Stay tuned. 】

The practitioner immediately called his friends, and soon more and more people came.

At 8:58 in the morning, the entrance of the pharmaceutical "research" center was already crowded with people.

Chu Fei showed up, "Everyone, be quiet."

When people saw Chu Fei appear and heard Chu Fei's voice, the surroundings suddenly became quiet.

Chu Fei spoke up: "The video is ready. Due to the difficult conditions, we have only found a projector for now. However, it will be available for download after it is played, so people who can't see it clearly don't have to worry.

The video is ten minutes long in total. After watching the video, the next thing will be revealed.

It’s almost nine o’clock, the countdown starts now.”

The projector was in place and the countdown had begun; at exactly nine o'clock, Chu Fei clicked on the video.

After a night of processing, the battle video between Chu Fei and Liu Jinhui can finally be watched, or to be more precise, ordinary people can watch it.

During the battle, both Chu Fei and Liu Jinhui moved violently and at very fast speeds. The video they shot was difficult for ordinary people to observe directly and had to be processed.

Now that the videos have been sorted out, it is natural to help the old city lord Liu Jinhui become famous.

In the processed video, you can clearly see Liu Jinhui rushing over, Chu Fei crushing the energy crystal, then Liu Jinhui's speed suddenly dropped, and then a fireball appeared out of thin air.

This record alone is enough to make everyone exclaim.

Those who have participated in the exploration of the Tianlong Secret Realm immediately exclaimed: "This is... magic?!

Yes, first crush the energy crystal to fill the surrounding area with energy for a short period of time, and then you can cast magic.

I never thought magic really existed."

The video continued to play, and when the crowd saw Chu Fei slap Liu Jinhui twice in a row, they burst into exclamations.

However, some people who understand explained: "The deputy city lord has no choice but to do this. After all, Liu Jinhui is a 12.0 master and a well-hidden Tianlong. I am afraid that even if the deputy city lord attacks with all his strength, he will not be able to break through his defense.

Specifically, full-strength attacks will cause the opponent to slow down and be avoided. Although fast attacks can lock on to the opponent, their attack power is weaker.

No matter how strong the attack power is, it is useless if you can't hit the enemy. So the deputy city lord can only choose to attack quickly. In the case of insufficient strength, humiliating the opponent is also a good choice. "

After a while, the scene was played where Liu Jinhui almost split Chu Fei's chest, but Chu Fei also chopped off several fingers.

Seeing this scene, the audience exclaimed even louder.

Then came the "Borrowing the Sword from a Straw Boat" segment. Everyone saw that Liu Jinhui would rather be stabbed by Chu Fei than not take the sword away.

The video ended, but the scene was silent.

The entire video is only ten minutes long - the actual battle is only two seconds long. A two-second battle, slowed down to ten minutes, allows ordinary people to clearly see the various duels and battles during it.

After a while, noisy sounds broke out again.

Chu Fei did not explain anything, but waited for a while to suppress the noise of the crowd, and then announced loudly:

"The second thing is that the Pharmaceutical Trading Center has officially changed its name to the Pharmaceutical Research Center. I think careful people have already noticed it.

The reason for doing this is that yesterday's battle has caused a large number of pharmacists in the Pharmacy Trading Center to be killed or injured, and a large number of medicines, medicinal materials, instruments and equipment have been lost and damaged. Now the Pharmacy Research Center is no longer able to take on the important responsibilities of the Trading Center. "

There were exclamations again. But Chu Fei's voice was louder: "After a night of consideration, the Pharmaceutical Research Center has decided to make public all commonly used pharmaceutical research methods, medicinal material identification and processing methods below 10.0.

After one night of sorting, more than 2665 kinds of medicines and more than 57 kinds of medicinal materials have been sorted out. The relevant video duration can reach 1.7 hours, there are related pictures and million words of related text.

The Pharmaceutical Trading Center copied more than 5 memory cards by itself, each costing yuan.

Or you can bring the memory card to the Pharmacy Trading Center to copy it yourself. It costs 4.5 yuan for one copy.

Please note that each content has been encrypted and cannot be copied or reproduced, otherwise it will cause garbled characters, etc. ”

After Chu Fei finished speaking, the scene became quiet again, but immediately an even louder noise broke out.

"More than 10.0 kinds of medicines. Does this cover all common medicines below ?"

"Is the video material from within the Pharmaceutical Trading Center?"

“Is the video adulterated, censored, etc.? Has it been cut at key points?”

"Pharmaceutical trading... No, the Pharmaceutical Research Center will no longer be involved in pharmaceuticals below 10.0?"

"Can even someone without any basic knowledge learn to make medicine?"

"Is it really only 50,000 yuan? Is it an auction or a sale at a fair price?"

...

Chu Fei stood at the door calmly, without saying a word.

Everyone was noisy for a while, and then gradually became quiet, but everyone was staring at Chu Fei.

Chu Fei spoke again: "Then there is the third thing. That is that the Pharmaceutical Research Center will only accept orders for pharmaceuticals above 10.0 in the future, and they will mainly be customized pharmaceuticals.

Because a large number of instruments and equipment were damaged, many experts were killed or injured, and a large number of medicinal materials and medicines were damaged, the Pharmaceutical Research Center decided to increase the current price of all medicinal materials and medicines by 50%!"

Not many people paid attention this time. Of those who came early in the morning, very few had a level above 10.0.

After a brief pause, Chu Fei spoke again: "Okay, the three things are also three major actions, and the announcement is complete.

As for the more than 2,000 memory cards, everyone can draw lots.

Those who don’t draw lots will queue up to copy.

Keep order on the spot, and kick out anyone who cuts in line."

Naturally, there were staff members to guide and arrange things next. Chu Fei watched for a while, felt a surge in his spiritual power, and left with satisfaction.

Not bad. It seems that even if the elites of the self-help association leave, I can still harvest a batch of pure spiritual power.

That's good.

Then Chu Fei returned to the secret room, looked at the equipment that had been adjusted in the secret room, and took a deep breath: "Next, I will forge a new sword, a better sword!
If you want to do your job well, you must first sharpen your tools. If you want to kill those who are not pleasing to the eye and want to get out of the Longmen Secret Realm alive, you must have an excellent weapon to escort you!"

Taking out the red copper and black iron, Chu Fei's eyes seemed a little dazed, but in fact he had already entered into crazy thinking and calculations.

Previously, there was only red copper. If you wanted to engrave a formation (manifold) on the red copper and make it effective, you had to use your true essence to engrave it. This process was actually very complicated.

But now with the black iron, there seems to be a new method.

After testing, Chu Fei determined that red copper was significantly better than black iron in energy conduction, so he could use red copper as the formation pattern and black iron as the basis for the sword embryo.

In this way, the buried thread method can be used to replace the seal carving formation method.

But it is not an easy task to accurately embed red copper into black iron.

If it is said that electroplating a layer of copper on iron sheet is simple, it can be done by electroplating, corrosion, high temperature spraying, laser ablation, etc.

But the problem is that red copper and black iron are not ordinary metals copper and iron after all.

As a high-dimensional metal, it has some special temperaments.

For example, if you want to form a chemical reaction with red copper, then the corresponding chemical substance must also be a high-dimensional substance. Otherwise, "reproductive isolation" will be formed, and red copper will not react with low-dimensional chemical substances.

As for high-temperature plasma spraying, it is also not advisable. High-temperature melting or plasma spraying will cause the properties of red copper to be destroyed, and the spraying accuracy is not enough, which will cause a lot of waste.

In fact, there is another way, which is to make iron sheets first, then insert them into molten copper liquid, and then use laser ablation. This will produce very good precision, but the waste will inevitably be great.

There was very little red copper and black iron. As long as there was a choice, Chu Fei would not waste it.

"If you want to forge a sword, you actually have to overcome the problem of craftsmanship!" Chu Fei was a little speechless. He always felt that this sword forging was weird.

If you look at various literary works, sword-making means just swinging a hammer and hammering it wildly, or forging it with real fire, such as hundred-fold tempered steel, thousand-layer steel, and so on.

How come when it comes to me, sword making requires chip manufacturing equipment, electromagnetic furnace, laser equipment, testing equipment, etc.

However, although it felt strange, Chu Fei still worked hard on his research.

The steps for forging a sword with black iron and red copper are similar.

But if you want to mix black iron and red copper to forge a sword, the difficulty will increase a lot. The main reason is that Chu Fei wants to save as much as possible.

However, hard work pays off, Chu Fei soon found a solution - ultrasonic welding technology!
In addition, there is cold welding technology.

The temperatures of both technologies are relatively low, especially the cold welding temperature is even lower, and there is almost no damage to the high-dimensional properties.

However, ultrasonic welding technology is easier to achieve because cold welding technology requires complete isolation from oxygen oxidation.

If you want to completely seal the device without affecting its accuracy, this is basically a no-brainer.

Unless the entire room is sealed and nitrogen is flushed in to replace the air, mainly the oxygen in the air.

Hey wait, that seems to work!
Chu Fei's eyes flashed and he thought of this crazy idea.

In fact, the best environment for real cold welding is a vacuum environment, followed by argon protection, but there is no equipment that can prepare a vacuum environment, especially to completely evacuate a room, which is simply impossible.

As for argon, it is a rare gas that requires a huge industrial system to support it. Where can I find argon in the apocalypse?

So, nitrogen is easier. The simplest way is to filter out oxygen by passing air through red-hot wire mesh, sodium magnesium aluminum powder, etc.

The oxidation products form solid particles that do not pollute the rest of the air.

This method seems to work!
I am a powerful practitioner and I don’t even need to breathe oxygen. Even if the whole room is filled with nitrogen, it will not affect me.

Of course, it is not recommended for ordinary people to try this method, but Chu Fei is not an ordinary person.

Then experiment and see which method works better.

This time when forging the sword, Chu Fei wants to forge the most perfect sword, reaching the limit of his current ability to forge.
