The sound of the tremor fell, and the dust dispersed.

On the edge of a deep pit, the ground bulged, and Yun Yi pulled open the layer of soil and crawled out of it.

He shook his head, shook off the sand from his hair, and looked around in confusion. At this sight, he woke up in fright.

Not far from his side, there is a large pit, about five zhang wide and more than two zhang deep.

This...... This is what that weird thing came about? This effect is estimated to be as good as the full force of the middle level of the saint level. That's a little too strong, isn't it? If that thing hits you, it won't shock people into fine powder? This is too lethal, right?

He was speechless in horror. The Wild Wolf Army actually has this kind of peerless killing weapon, if they distribute this thing to the whole army, what will the Northern Army use to fight, and who will be the one general? I'm afraid no one can do it, and all the people will have to be killed.

No, I'm going to send this news back to make the Northern Army more alert. As soon as he moved, he suddenly felt a terrible pain in his back. When I touched it with my backhand, it was full of blood.

He wailed and couldn't help scolding, "I'll be your aunt." ”

He hurriedly took out two healing pills and took them to dissolve the medicinal properties. As the tingling sensation came from his back, he gradually calmed down. At this time, I really can't go back to report the news, I don't have any credentials. Those generals may not be willing to believe it, and it is estimated that they will slander me, saying that I am lying to confuse the people and disturb the morale of the army.

This matter has to be considered in the long run.

discovered the deadly crisis on the battlefield, but couldn't talk about it, Yun Yijue's abnormal grievance. He gritted his teeth, fuck you, everyone has a life, love to death or not. I'll heal my wounds first.

He didn't go far, but simply jumped into the pit, like a gopher, made a hole, got in, and sealed the hole.

Sitting cross-legged in the cave, he carefully probed the changes in the aura in the deep pit. With closer inspection, the monster that was in hot pursuit ...... Wait, he remembered, the general of the Wolf Army seemed to have said that the thick tube was called the Vitality Locking Cannon.

The monster was emitted by it, and it seems to be called a cannonball.

Yun Yi probed the aura fluctuations in the deep pit and quickly figured out the explosion mechanism of the cannonball. There was a sufficient amount of spirit stone compressed in it, and it seemed to be a fire-type spirit stone. It is precisely because of this that the shells have amazing lethality and destructive power.

Lifting the veil, Yun Yi snorted coldly. I thought it was such a profound thing, who knew it was so simple. If you can make it, so can I, and I'll let you taste my power.

The fire spirit stone, Yun Yi does not have it, but he does not lack pure aura, and it is easy to make it into an aura crystal.

The only thing he didn't understand was that the cannonball was obviously uncontrolled, so how could he lock it and chase after it?

"That's the magic of the formation. Tang Rui explained.

Yun Yi frowned, this is impossible, there is such a profound thing on a small cannonball, then it will be difficult to make.

"There is a kind of locking spirit array in the formation, which can not only lock the aura and prevent overflow, but also lock the breath of people. People are different from each other, and the breath is naturally different. Even if it can be imitated, there will be small gaps. If your breath is locked, there will really be a situation of non-death. Tang Rui explained.

Yun Yi thought for a while, frowned, and said, "If I want to make that kind of locked cannonball, do I have to learn the formation first?"

"It can only be so. Tang Rui analyzed: "But it's not all. Cannonballs are not made casually, the material of the shell and the firing trigger device are all a science, which involves spirit runes. No matter how talented you are, you can't achieve it overnight. ”

Yun Yi had a slight aftertaste and couldn't help but scratch his hair. How does it feel like this is a huge project?

"To tell you the truth, this weapon of large-scale destruction is a hot weapon, and it is the opposite of the cold weapon represented by the sword. It's the result of wisdom. It is also the crystallization of the creativity of the group. If a person wants to do it, without decades of hardship, he will not see the results at all. Tang Rui said.

Yun Yi asked in surprise, "How do you know so clearly?"

Tang Rui said with a smile: "In this land, there are not many things I don't know. Do you remember the aliens outside the lake?" (see Chapter 53 for details)

Hmm?Aliens?What does thermal weapons have to do with them?Yun Yi thought about it vigorously, and seemed to be a little impressed. The man blended in with the crowd, with a light yellow beard, blue eyes, and a large nose.

At first, it was just a glance, but it also left an unforgettable mark.

Yun Yi was not impressed by him, but the three alien races that appeared in the Medicine King City had close contact with him. When Tang Rui said it at this time, he felt that the problem was not small. (See Chapter 62 for details.)

"These thermal weapons, that's what they developed. You have also seen the power, an ordinary person can kill a saint-level master. You say, how lethal will their holy level be?" Tang Rui said.

Yun Yi guessed dumbfounded: "Emperor Zhu and Emperor Destroy?"

"Almost. Ever since I saw them appear, I had expected that your days of peace would come to an end, and that a great war would break out. Tang Rui said.

Yun Yi was stunned. Isn't that the reason why there are only a few of them? There are hundreds of millions of people in the Daxing Empire. Even if they had powerful thermal weapons, they wouldn't be able to carry a lot of people.

"Don't believe me, boy. Their combat power is enough to wipe out the entire Daxing Empire, and absolutely no one can compete with them. I advise you, don't go anywhere in the past few years, and find a place to concentrate on learning the manufacturing and formation skills of the spirit rune. It's really a big battle, and you have a chance to show it. Tang Rui suggested.

"I want to settle the matter of the Yu family first, if this matter is not resolved, I am like a fish in my throat. Yun Yi replied.

Tang Rui was silent for a moment, "Then you should know that there are emperor-level and emperor-level masters among them, and it is useless for you to fight against them now." Even if you know the truth, you can't kill them. ”

"Then I'll vent my anger first and collect some interest. The more unhappy they are, the happier I am. ”

Tang Rui smiled, "That's okay, wait until you heal your injuries, get some shells, and blow them up." Perhaps, if you do this in their nest, you can still get miraculous results and rewrite the situation of the battlefield. ”

Yun Yi thought about it, as if it could really be like this, and he was very happy to look forward to it.

The injuries on his body were not serious, after all, he had the double protection of Gangjin and Linjia. He will be recuperated for five days, and his injuries are completely healed.

After a hearty wash, he changed into a new set of clothes and worked intensively to make the simplest cannonballs in the hole.

He figured out the trigger mechanism of the shell. He stores the fire crystals that have reached the critical point of explosion in the rear end, and also stores a certain amount of crystals in the front section, as long as the front section is hit or externally forced, as soon as the rear end touches, the shell will explode.

To add power, he also added a sharp blade to the rear end. As long as the shells explode, these blades will surely take people's lives.

As for how to launch, he didn't come up with a way, but he wanted to use a bow and arrow, but the firing distance was too short. Simply, he wanted to throw with his arms.

After half a month of busy work, he made two hundred and twelve.

Just as he was about to get out of the cave by hand and do a big job, there was a sound of talking outside the cave.

"This should be it. ”

"Have you measured the distance, how far is the range?"

"Nine hundred and thirty-seven miles, it should be that all the driving fuel has been burned out. ”

"It's a good distance, and the locking effect is not bad, but the pursuit bomb didn't kill the intruder. This point needs to be improved, and the disadvantages of relying solely on triggers are too obvious. ”

Yun Yi heard it, and it was the general in the valley who was speaking outside. He actually found it, and he commented on the cannonballs.

Could it be that he is an expert in weapons.

I even wanted to trouble you, but you came, what a coincidence. It's time for revenge.
