Early the next morning, Zhou Qing got up from the bed, and after waking up, he immediately urged his mental power to see if it was enhanced, but the effect was not very obvious, which made him a little disappointed, and at the same time pinned his hopes on the remaining honey.

The movement here woke up Li Yinsheng, who was sleeping, he got up and glanced at Zhou Qing, and corrected: "It's not like this, you have to let your brain and mind move together!" ”

"What do you mean?" Zhou Qing was puzzled.

"I'll tell you, Mr. Li!" Li Yinsheng smiled and took the opportunity to take advantage, of course Zhou Qing would not eat his set, with an attitude of not talking.

"Ahem~ Okay, don't make trouble, in fact, the awakening level and the green level are only one step away, it depends on whether you can comprehend and take this step!" Li Yinsheng said, next, he began to teach Zhou Qing how to convert spiritual energy.

Zhou Qing frowned, and he couldn't understand what Li Yinsheng said, but fortunately, Li Yinsheng had enough patience, and Zhou Qing had a good understanding, and gradually understood the specific method of combining energy and aura into spiritual energy.

Then Zhou Qing grabbed that feeling, his mental power was activated, his hair turned slightly green, and then he only heard a click, and the chair handle was twisted in the air!

"This is the green level?" Zhou Qing looked at the handle that was twisted by his own mental power, and was secretly speechless.

"Yes, this is the green level." Li Yinsheng nodded, "It sounds very simple, but in fact, not many people can take this step, after all, the concept is too abstract, and few people can understand the approach." ”

Zhou Qing agreed very much, at first he listened to what Li Yinsheng said...... When energy and aura were combined, he was also confused, and he couldn't find any way, until Li Yinsheng took the trouble to cite various figurative or abstract examples, which made him gradually understand.

Then Zhou Qing grabbed the feeling just now, and threw a punch, and the fist wind emitted a blue light.

Seeing this, Li Yinsheng felt a little envious in his heart, there were both physical and cerebral abnormalities, which sounded like a template for the protagonist, and he also wanted it.

"And after that? How does the Green level advance to the Bronze level? Zhou Qing asked, these secrets are currently only circulating in the Eastern Capital Deviant School, and even the superiors may not know, after all, the person who can be the principal of the first Deviant School will not be so simple.

"After that, it is the accumulation of aura, and this stage depends on personal talent, people who are sensitive to aura absorb efficiency quickly, and those who are promoted quickly. When the aura in the body changes from gaseous to misty and envelops the whole body, then use the method just now to fuse the energy and the mist-like aura, which is the bronze level! ”

"After advancing to the bronze level, there should be a period of aura accumulation stage, and then combine the aura that is thicker than the misty aura with energy, which is probably the so-called silver level...... That's my guess, but it's not far from ten. Li Yinsheng said.

……

Xie Yan's side began to invent new weapons again.

There is no way, the gun needs to use silver-level psionic energy, and he can't afford to play it at the moment, so he can't equip it on a large scale, so he can only find another way to see if he can get the rocket artillery out. Unlike guns, this thing doesn't need a barrel or barrel, as long as there is a gun mount and a stable booster device.

So Xie Yan began to tinker with the new pipe.

The inside of the tube is divided into two sections, front and rear, and the whole can be divided into three structures: the arrow, the arrow body and the balanced tail. Needless to say, the arrows were loaded with an aura bomb. The body of the arrow is a hollow structure, filled with mist-like aura. In addition, Xie Yan also got a plant launch pad out.

Everything was ready, Xie Yan roughly adjusted the angle, and counted down to three, two, one.

The moment the plug at the tail of the rocket launcher was pulled off, the mist aura spewed out, pushing the arrow body to fly forward with a whizz, extremely fast!

"That's it?" Xie Yan couldn't believe the scene that was happening in front of him, he had made so many bronze cannon barrels before, and none of them were qualified, and the rocket artillery was a one-time success?

Incredible!

made Zhi sigh.

Soon, the mist aura inside the rocket was consumed, and the arrow body began to fall, because the arrow was heavier, so it would hit the stone in one step, and finally trigger the aura bomb on the arrow.

Rumble!

The aura bomb exploded entirely, and the nearby eye plants were directly wrung off by the shock wave.

Hua Xiong, who was digging a nest on the mountain wall, was startled by this movement, and he turned around and roared a few times in protest with a dissatisfied face.

Xie Yan didn't bother to pay attention, he just silently repaired the eyeplants near the explosion site, and then continued to build rocket artillery to test the specific launch success rate and accuracy, after all, a successful launch at one time can only be said to be luck, and it is impossible to determine whether there is some kind of hidden danger in the arrow body itself.

After many tests, Xie Yan found that the stability of the propulsion device is very good, basically as long as it can be built, it can fly out, as for the hit rate, it is another thing, to put it simply, it is a disaster!

It's like a middle-aged man going to the toilet to urinate, flying around! One of them also turned in the air and flew towards Xie Yan......

"!" Xie Yan was very depressed, fortunately, these experimental rockets were not equipped with aura bombs, otherwise they would have really blown themselves up.

After a round of testing, the hit rate of the rocket artillery was 3 percent, and Xie Yan estimated that this 3 percent might just be a blind cat encountering a dead mouse, so the real hit rate should be 0 percent......

However, in the process of testing, Xie Yan also had some ideas on how to improve the hit, and he planned to add a few more jets to the planting rocket, and apply forces in different directions to the rocket through multiple air holes, and finally achieve the balance of the rocket body.

"Big project!" Xie Yan took two deep breaths of carbon dioxide.

The position of the air hole, the angle of the jet need to be constantly tried, and if you are unlucky, thousands of rocket launchers will not be able to try a reason, in addition to the intervention of air currents, etc., so if you want to fly farther, you must solve all these problems.

In addition, Xie Yan also prepared another backup plan, in case the rocket artillery can't be made, that is, to retreat to the next best thing, to engage in lower-level ballistas and catapults, anyway, as long as he can throw the aura bomb out, he will have the capital to fight with the conventional combat power of human beings!

"A month! If you can't try it in a month, you won't get it! Xie Yan set a time for himself, after all, he only had nine months to squander.

The test began, Xie Yan turned a deaf ear to what was going on outside the window, and only engaged in rocket artillery. In order to be able to test multiple rockets at the same time, he built dozens of launch pads on his own turf, and installed them whenever he had a new idea. And as the number of experiments increased, he gradually found some doorways.

For example, if you want to be unaffected by air currents, the best way is to make the rocket spin, for which he specially installed two small airbags on the tail, these two airbags will also be jet, and their function is to make the rocket launcher rotate in the air.

Another example is the issue of launch angle, Xie Yan found that the angle of 45 degrees is not the best, it must be lower, about 43 degrees is the best angle for shooting, because when the rocket is launched, it will be suddenly stressed, causing the rocket arrow to unconsciously lift up a little bit.

When Xie Yan was trying to test, Hua Xiong encountered difficulties here, he wanted to dig a hole in the mountain wall to make a nest, but the more he dug in, the harder the mountain rock became, and now it couldn't dig it at all.

"Vomit~~" Hua Xiong turned to the owner for help, but Xie Yan concentrated on the big project and didn't have time to pay attention to it. It could only walk up to Xie Yan aggrievedly, began to splash and roll, and when Xie Yan ignored it, it ran to destroy the launch pad......

"Stop, there's something to say!" Xie Yan was a little helpless and could only suspend work.

Hua Xiong rushed back, and the bear's paw pointed at the mountain wall that had been dug less than halfway, and all kinds of grievances sounded from his mouth.

"Can't dig it?" Xie Yan was a little surprised, Hua Xiong's claws had completely turned bronze, which was a genuine bronze grade, and it stands to reason that it was not too difficult to open a mountain and split stones.

Xie Yan stared at the excavated concave surface for a while, and then spawned an eye plant nearby, and at the same time installed two bronze vines on the eye plant, and transformed the front end of the vine into the shape of a chisel and a hammer.

Ding Ding Ding ~

Xie Yan began to dig the hole, but before he could dig a few times, the bronze chisel head snapped and broke!

"Huh? So hard? Xie Yan felt that something was wrong, and when he looked closely, the stones on the mountain wall were faintly cyan!
