Time and Space Trading: I exchange a bottle of water for nuclear fusion

Su Yu glanced at the Soul Devouring Jade with lingering fear.

"Then what did you mean when you said that this is not a perfect method? Are there any disadvantages?"

"The disadvantage is that the living soul cannot be preserved for a long time. At most, the living soul can only stay in the world for half a year. After half a year, the living soul will still slowly dissipate."

"Half a year?" Su Yu nodded:

"That's fine."

He has a transdimensional trading platform, so it is not surprising that he can be matched with trading partners from any world in the future.

There is no guarantee that you will meet a trading partner from a world with stronger extraordinary powers, who can live and die.

Although Soul Eater Jade can't be done once and for all, but after half a year, there will be more possibilities.

But at this time, he thought of another question:

"If the soul is absorbed into the Soul Eater Jade, can it communicate with the outside world? Or is it similar to a prison dedicated to imprisoning souls, and after entering it, it will no longer be able to communicate with the outside world?"

If it's the latter, I'm afraid Qiu Mo will have to go to jail.

"If there are no alchemists who are proficient in this way to set up restrictions, it is natural to be able to communicate with the outside world. Whether the Soul Eater Jade is a sinister magic weapon depends on who it is used for." Ying Zheng said patiently:

"In the hands of those alchemists with evil intentions, they will use various restrictions to imprison the human soul in the jade pendant, and then set some punishments such as karmic fire in the jade pendant to torture the soul, and use it as a tool of torture."

"And if you just want it to be a carrier to renew the life of the soul that has lost its body, then it is the most suitable treasure in the world for nurturing the soul. Naturally, there is no problem in communicating with the outside world."

"That's good!" Su Yu nodded in satisfaction:

"What about the price? What does Your Majesty need?"

Ying Zheng knocked on the table when he heard the words, pondered for a moment and said:

"Actually, this item is an orphan. It was a coincidence that an alchemist from the Yin Yang family collected this black jade and refined it according to the ancient method. It is difficult to replicate."

"If you talk about its function, it is actually limited. It probably has no other use in Daqin except as a torture tool. But if you want to say that it is of little value, after all, it is the only thing... the price is up to you. Go ahead and give it."

Do you look at it yourself?

Su Yu thought for a moment, then asked:

"Then I don't know if His Majesty has any difficulties recently?"

"Difficulties..." Ying Zheng raised his brows and muttered:

"Speaking of which, there are indeed some difficulties."

"Although Meng Tian led his troops to attack the Huns in the north, the Huns were good at riding and shooting. They came and went like the wind. It was easy to defeat but difficult to kill."

"I originally wanted to build the Great Wall to defend against the enemy, but after reading the things you gave me in the past few days, I realized that this move was really too hasty. The Great Qin just ruled the world, and the people's livelihood is dying. Conscripting civilians to build the Great Wall will inevitably lead to people's resentment. "

"But if the Great Wall is not repaired, if the Huns cavalry go south to plunder again, Meng Tian may not be able to stop them again. Then the northern border will be a place for the Huns to run horses."

"Infantry fighting cavalry, this is indeed a historical problem." Su Yu touched his chin.

Of course, it is impossible for Daqin to have no cavalry.

But there is only a thousand days to be a thief, how can there be a thousand days to guard against a thief?

Compared with the long national border in the north, and the lack of information in that era, it is impossible to judge in advance which direction the enemy is attacking from these factors.

If there is no Great Wall, facing a sieve-like northern defense line, it would be too easy for the Huns who come and go like the wind to come and plunder.

They run away after grabbing a wave, and when your army arrives, the city will be slaughtered.

"Qin Huang knows our world, why did the cavalry eventually withdraw from the stage of history?"

"Because... the gun?" Ying Zheng said with some hesitation:

"I have recently watched a lot of documentaries about your so-called world wars. It has been mentioned many times that the cavalry has withdrawn from the stage of history because of the existence of those powerful firearms."

"Yes, not right." Su Yu shook his head and said:

"The popularity of automatic weapons has indeed prevented cavalry from being fierce on the frontal battlefield, but are cavalry only strong on the frontal battlefield? Obviously not! The biggest advantage of cavalry is mobility. There is a saying in our side that martial arts in the world can only be broken by speed! "

"If you have a gun, others can also have guns. But they have four legs, but they can always run faster than you with two legs."

"So what really made cavalry out of the stage of history is actually not the gun, but the internal combustion engine."

"Those cars and tanks?" Ying Zheng's eyes lit up suddenly!

Yup!

It's not that the soldiers of his Great Qin couldn't beat those Huns. In front of the Great Qin crossbow array, no cavalry could do it well!

But the biggest reason why the Huns can't catch up is that they can't catch up, not that they can't beat them!

Even if you equip the soldiers of Daqin with heavy machine guns, it won't matter if they don't fight you!

"Sir, do you have a good plan?" Ying Zheng couldn't help asking.

......

Chapter 61 Do you understand what is Daqin Superman?

No wonder Ying Zheng was in a hurry.

Doesn't he know that the Great Qin is waiting to be revived?

Obviously impossible.

The main reason why he insisted on building the Great Wall before was the border troubles in the north.

In his era, facing the harassment of nomads on the grasslands, there was almost no other way except to build the Great Wall.

This is determined by the characteristics of civilization, and it cannot be controlled by him.

Without the help of fortifications, even if the farming people who lack horses can fight on the battlefield, it will be difficult to win the nomads.

The reason why the later Han Dynasty was able to reverse the cutting of the grassland was because they prepared for it for decades and raised countless horses in the Central Plains.

Daqin does not have this condition now.

"It's not a good strategy, but I do have a solution that can help you solve the border problems in the north in the short term. As for the future...when Daqin is industrialized, these problems will naturally disappear."

Su Yu smiled and waved.

A nearly two-meter-high armored monster appeared beside him:

"Heavy exoskeleton!"

"Wearing it, the soldiers of the Great Qin Dynasty can carry a heavy load of ten stones and run for five hundred miles in one hour! Moreover, this thing is invulnerable to swords and guns, and its power is infinite! With it, even if you meet thousands of Xiongnu soldiers, you can go in and kill them alone. He gets in seven and out!"

The unit of stone has been changing. During the Qin Dynasty, one stone was equivalent to more than 100 kilograms.

In the Qin Dynasty, one mile was roughly equivalent to more than 400 meters now, and one hour was about two hours now.

After knowing that his second transaction partner was Ying Zheng, Su Yu went to make up for this knowledge.

"Is there such a fetish in the world?" Ying Zheng immediately got up and came to the exoskeleton.

His eyes glowed as he looked at this creation that condensed countless cutting-edge technologies.

"Of course, if there are a hundred soldiers wearing this armor to guard each pass in the Northland, the Northland will be safe. If you want to take the initiative to attack, it is not difficult. I can find a way to do some investigation for you. Machines and other equipment, I am not afraid that the Huns will not be found on the vast prairie."

Su Yu assured with a wave of his chest.

Just kidding, wearing this thing will immediately let the Huns know what a Daqin Superman is!

He can even imagine the scene where the Great Qin warriors put on exoskeletons and entered the Huns Dragon City seven times and seven times out.

You Huns come and go like the wind?

Can an exoskeleton run at a speed of [-] kilometers per hour?

Hit, can't beat!Run, can't run away!

Hiss, the picture is too beautiful.

What, the per capita prenatal education of the soldiers of the Great Qin Dynasty did not go to high technology?

Don't be afraid, he can send a few bionics to be instructors.

One thing to say, the bionic man is really easy to use!

"How much can Mr. Su provide?" Ying Zheng asked repeatedly.

"I can give you a hundred sets in exchange for the piece of Soul-devouring Jade, what do you think, Your Majesty?" Su Yu gave his own price.

"Yes!" Ying Zheng immediately agreed.

Let alone a hundred sets, a piece of soul-devouring jade that is not very useful, he would have to wake up with a smile if he could exchange for a set of such an exoskeleton.

Although there are indeed alchemists with special abilities in the world he lives in, these alchemists are limited to refining alchemy and refining some magic weapons.

Occasionally, there will be a few enemies of thousands of people and enemies of ten thousand people who have practiced the method of refining qi to a high level.

But even this kind of person is nothing more than flesh and blood.

Under the siege of the army, facing the sky full of arrows and swords and guns everywhere, once entangled, it is actually very difficult to escape.

After all, no matter how hard a body of flesh and blood is practiced, it will eventually be injured.

And human physical strength is limited.

Even if it is the enemy of ten thousand people, it is impossible to really be able to kill ten thousand people with one hand, it is just a saying.

After fighting for a long time, his physical strength is exhausted, and he can only wait for death.

But the soldier wearing the exoskeleton, in Su Yu's description, obviously surpassed the concept of an enemy of ten thousand.

With this terrifying power and speed, coupled with the invulnerable armor, arrows, knives and guns can't do anything to others.

Ying Zheng estimated that even a hundred thousand troops might not be able to capture him, and he could get away with ease.

Isn't this much better than the soul-devouring jade fragrance that is useless?

This deal is profitable for him no matter what.

For Su Yu, this deal was also profitable.

After all, the exoskeleton, to put it bluntly, costs only a little.

The biggest problem may be the energy problem of the black box. After five years, if there is no energy, it will not be used.

But now he has a peregrine falcon, and when the black box has no energy, it is not difficult to drive directly to the moon to collect some helium-[-], and this problem is basically not a problem.

Saving Qiu Mo's life with a hundred exoskeletons must be profitable for him.

After all, the help and value that a close aunt like Qiu Mo can bring to him is far more than a hundred exoskeletons in this area.

Another win-win!

After the two parties signed the transaction contract, Su Yu drew a hundred sets of exoskeletons from the inventory to Ying Zheng.

By the way, he also gave him two androids who knew how to operate the exoskeleton.

Then he said:

"The power source of this exoskeleton is a battery, and the power in the battery is probably enough to support the soldiers to run more than 2 miles in it."

"Replacing the battery is not difficult. I will teach you how to operate these two bionics."

"One hundred exoskeletons are items for trading Soul Eater Jade. As for the subsequent batteries, they need to be traded separately. If Emperor Qin wants more exoskeletons, I can provide them here."

Because of the existence of those popular science videos, he didn't need to spend any more time explaining to Ying Zheng what a battery was.

"It should be so." Ying Zheng nodded without any objection, but then said:

"However, this thing is too powerful, how can I ensure that the person who wears it will not rebel?"

Su Yu can understand his worries in this regard.

After all, even in modern times, there are still cases of pilots flying in airplanes in some countries.

Not to mention the Qin Dynasty.

Loyalty or not, in fact, often depends on the position of the individual.

When a person has mastered unprecedented terrifying power, he may not be as loyal as before.

As a feudal monarch, it is normal for Ying Zheng to have such worries.

"You can bind the ownership of the exoskeleton in advance before releasing the exoskeleton. In this way, the highest authority of all the exoskeletons is with you. As for those soldiers, they only have the right to use them. When they are in front of you, you They can stop their exoskeleton in just one thought. You can ask the bionic person how to do this, it should not be difficult."

"As for wanting to wear this to escape from Daqin, go to other places to dominate, and never come back. That's even more impossible. The power of the exoskeleton is not unlimited. If you control the battery, you control their lifeline .”
