I haven't seen fireworks.

During the seven months of traveling with Shennong, in addition to treating diseases, researching light escape, and researching alchemy strategies, he is also doing one thing: collecting and integrating the kendo obtained from the ruins of Liuyi.

After all, he has gained a room full of swordsmanship. It would not be a waste if he did not learn.

The Six Senses of Kendo was able to dominate the samurai world before the ninja sect, which is certainly commendable. Although it later declined, and most of the inheritance declined, didn't later generations add a lot more, and there was also a Six Senses sword Holy.

The essence of Liuyi Kendo lies in this name.

Yi does not mean loyalty, but refers to classification.

The six meanings are the six classifications, which are attack, defense, rotation, fast, slow, and storage.

The six categories are grouped in groups of three and three, and combined in pairs, which are the nine secrets of fast attack, slow attack, charged attack, fast defense, slow defense, charged defense, fast spin, slow spin, and charged spin.

Nine kinds of mysteries, with various styles and changes, for different kendos, you can use different mysteries to deal with them. After mastering the nine kinds of esoterics, you can break the world's swordsmanship!

It can be called the ninja world’s version of Dugu Nine Swords!

It's a pity that this Liuyi kendo can only deal with kendo, and it won't work against ninjutsu that uses elemental attacks. How can you resist with a sword when a big fireball hits your head and face?

It would take a member of the Liuyi family to learn the nine mysteries, and it would take them seven or eight years to become proficient, and more than ten years to become proficient, at which point they could already be called sword masters.

Liuyi Shinxuan was gifted with extraordinary talent. He also learned swordsmanship at the age of three and became a saint at the age of 12. It took him nine years.

But Sun Jingyun has the system of heaven rewarding work, and the Yuanling Yuchi is open, and it took only six months to master it. In the remaining month, he also tried to add elements to the sword to fight against ninjutsu .

At present, adding thunder and wind elements to the sword is going very smoothly, but other attributes are not going well.

Because metal can conduct electricity, wind can attach to the sword, but it is difficult to inject mana from other attributes into the sword.

Of course, Yunque didn't know that there was a sword master sitting next to her. After listening to Sun Jingyun's words, she suddenly frowned: "But practicing swordsmanship is very expensive. I saw it in a ninja shop before, and it was an ordinary sword." It costs 500,000 to 600,000 taels. If you start learning now, by the time you graduate, you will need to replace two or three swords in four to five years, and my family cannot afford it!"

"Then you can practice kunai fighting!" Sun Jingyun said, "kunai is small and exquisite, and it's easy to use. It's more suitable for girls."

"I don't need it!" Hibari waved his hand: "My dream is to become a ninja teacher like Umino-sensei, and I don't need to fight..."

"Okay!" Sun Jingyun shrugged, he didn't care anyway.

What he has to do now is to hide himself silently, develop silently, and survive silently until graduation.

After all, although his fighting power is strong, he uses mana that is extremely difficult to accumulate. Every time he uses it, he loses it, which makes him feel quite distressed.

He wants to slowly settle himself in these precious four years.

As for the goal, when you graduate, break through the Qi refining stage!

After school, Sun Jingyun returned home and went directly to the underground hive.

The originally empty beehive has already been decorated with many rooms by him.

For example, bedroom, alchemy room, practice field.

When there was no actual combat class, he decided to let the avatar go to class. As for the main body, he hid underground to make alchemy!

After seven months of continuous research, he finally found a way to use magic power to concoct medicinal materials.

It's not that using fire is not enough, but that specific medicinal materials need to use specific elements, and it is best to combine the processing methods of the original medicinal materials.

For example, if some medicinal materials need to be dried in the sun, then fire is used.

If some need to be boiled, use water.

Some need to be ground into powder, then use the earth element.

Time was limited, and he didn't have time to experiment with the processing methods of 4600 medicinal materials, so he had to pick up the most important ones first.

For example, Bu Yuan Dan.

Shennong gave him Buyuan Decoction. The prescription is Polygonatum 5 qian, Atractylodes macrocephala 4 qian, Fushen 4 qian, Rehmannia glutinosa 4 qian, Jiu Baishao 3 qian, Astragalus 3 qian, cinnamon 5 qian, and licorice (burned) 1 qian.

Without causing negative effects, he added ginseng, and the efficacy of the whole medicine suddenly increased a lot.

He has also drank the soup made from this medicine, and it does have the effect of replenishing chakra, but because it is boiled and used, the effect of the medicine is much weaker after all.

He specialized in these kinds of medicinal materials and spent half a year researching the processing methods of various medicinal materials.

But research is research, and this is the first time for specific alchemy.

"Huh!" He breathed a long sigh of relief. Although he had the "Qing Jing Sutra", he still couldn't calm down in his heart.

After all, whether he can succeed in refining alchemy will determine whether he has only 150 mana or 1.5 mana when he graduates...

Let's do it!

The alchemy furnace he uses is similar to a pressure cooker. It is a completely enclosed space after the lid is covered. It can be filled with firewood, or directly roasted with fire spells. This is to create a high-temperature and high-pressure environment.

After all, he only knew how to concoct medicinal materials, but he didn't know how to condense these active ingredients together.

After thinking about it for a long time, there is only one way, which is to work hard to create a miracle.

Under high temperature and pressure, even gold can be crushed into a black hole, and different medicinal ingredients can naturally be condensed into elixirs.

The pressure created by burning water vapor alone is far from enough, so Sun Jingyun asked Yun Xiao to spend time modifying Gao Tianchangge, and a ninjutsu that exerts pressure from all directions to the center was born.

Since it was used to condense pills, he didn't bother to use other names, and just called it the Art of Condensing Pills!

This technique, combined with the closed environment in the furnace and the high pressure generated by the water vapor, is enough to make the pressure in the furnace reach an extremely high level.

The whole process sounds complicated, but in fact the principle is not complicated. It is nothing more than using magic power to select the active ingredients of the medicinal materials, and then condensing them together with force.

It's a bit like making compressed biscuits, but the medicinal materials he compresses are not biscuits, but elixirs.

After all the medicinal materials were processed, they turned into powder. Then Sun Jingyun put all the powder into the alchemy furnace, stirred it thoroughly to make the medicinal powders fully uniform, and then started to pressurize!

The powdered medicine quickly condensed together under high pressure, forming a glistening white, smooth pill.

"Is that all it takes?" Sun Jingyun felt the elixir in the stove with his divine sense, but felt something was wrong.

The surface of this elixir is too rough!

Roughness means that the powder he ground is still too big, and it also means that there is still room for compression!

Raise your hands and make a seal!

At this time, mana is too extravagant. After all, my alchemy is used to increase my mana. It is okay to use mana to make alchemy, but if I can't make ends meet, then I will lose money!

Naturally, use chakra to condense the pill!

It was the first time for him to use chakra from this angle. With the powerful oppression of wind attribute chakra, Sun Jingyun even felt a heavy burden on his spirit!

But fortunately, there is room for the pill to condense further!

"That's right!" Sun Jingyun originally used pure fire attribute chakra to burn the fire, but at this time, wood attribute was added abruptly.

When a wood fire is made, the original flame temperature suddenly rises a notch higher. With the temperature in the furnace, the pressure also suddenly rises a lot!

"No wonder alchemists have to choose the dual attributes of wood and fire!" Sun Jingyun didn't wipe his sweat with his hands, so he could only lower his head and wipe his sleeves.

After pressing it for nearly thirty seconds, he finally felt that there were no more wrinkles on the pill, but it had become smooth and white, as clear as a pearl!

"Wuhu!" Sun Jingyun finally breathed a sigh of relief, then released the alchemy technique, and opened the lid again.

Under the high pressure, the elixir collapsed directly. He quickly reached out to fish it out and held it in his hand, and then he was speechless.

Just now he looked at it with his spiritual sense, looking at the details. Now that he had it in his hands, he realized why the elixir was so small!

Not only does it not have the appearance of a dragon and a tiger, nor does it have the legendary pill pattern, but it is also quite small, only as big as a mung bean?

"It's because the medicinal materials are too little! If it's small, just make it bigger later. The key is the efficacy!" Sun Jingyun knew that there were no toxic ingredients in the medicinal materials, so naturally he didn't worry about erysipelas and stuffed it in directly. In the mouth.

There is no such thing as melting in the mouth, he feels like he has swallowed a mung bean, and he can't bite it.

But after swallowing it, he immediately felt the power of the medicine dissipating.

Sit cross-legged and refine chakra.

His chakra is definitely the type that is not enough compared to those above, and is also insufficient compared to those below.

If your own chakra level is 1, those students in the class have an average of 3~5.

The current Uzumaki Kagura may have 1200.

This is actually normal. After all, the Kamiya family is not a ninja family, and his talent is certainly not as good as that of the teenagers in the ninja village.

And the performance of the small amount of chakra is that every time chakra is refined, not much can be extracted at all.

But now, he found that his chakra was still not much, but he felt a constant flow!

"The elixir is ready!" Sun Jingyun suddenly became excited.

Damn it, it’s been a year since I traveled through time, and I finally solved this problem. Do you know how I spent this year?

Ordinary people, if they get rewards from heaven, they don’t need to cultivate immortals, they just bury their heads in the road of ninjas and run wildly!

That is, Sun Jingyun, who was born with insufficient chakra, knew that no matter how hard he studied, no matter how strong his ninjutsu was, what's the use without chakra?

Part of the reason for cultivating immortals is a long-cherished wish, and part of the reason is helplessness!

If you don't practice immortality, you can't fight with just that little chakra.

He suppressed the excitement in his heart, and then slowly moved the chakra to see how much the elixir improved himself at this moment.

Because it is not a pill that melts in the mouth, it takes a long time for the medicine to be effective. It took Sun Jingyun half a day to digest a pill that was the size of a mung bean.

The end result is that his mana has nearly doubled!

"Fuck!" Although I know that such a big improvement is due to the small base, it is too obvious!

Doubling it in half a day, 150 servings, doesn’t it only take 75 days?

What originally took five years to achieve now only takes two and a half months!

This is the power of pills, this is the power of krypton gold!

Sun Jingyun immediately grabbed a portion of the medicinal materials, no, 5 portions!

A mung bean-sized elixir is too small, at least it has to be the size of a marble to be normal!
