It's been a busy day.

Chen Qingshi finally settled one-fifth of the order.

Now that he repairs and maintains a one-star weapon, it is basically Zhang Fei eating bean sprouts, a piece of cake.

Even, after seeing Duanmu Mingcheng's 3D modeling, I want to try two stars.

He had thought about it, so he would upgrade the power of his new weapon first.

This is also the meaning of Jiang Xingwang.

Chen Qingshi's progress is far faster than he imagined, and the foundation of the forging master has also been supplemented through after-school homework and preaching and answering questions during this time.

It's time to take on the challenge.

It just so happens that Duanmu Mingcheng's optimization plan is very perfect, and the three hundred drawings and the method of upgrading the "era" to four stars are clearly explained.

The route of the "Era" from one star to two stars is relatively simple.

Silver-grey round tube, two ports.

The port that operates the condensate iron sand has been made by Chen Qingshi is relatively perfect, and Duanmu Mingcheng can only put forward thirteen suggestions for improvement.

The other port, the end of the muzzle shot, is very rough.

Duanmu Mingcheng has been obsessed with firearms and weapons since he was a child, and he is simply an expert among experts in this area, and he used one hundred and fifty-four drawings to explain his plan to transform the internal structure of the round pipe.

Based on Chen Qingshi's electromagnetic ability, the diameter of the electromagnetic gun can be used as a reference to miniaturize it.

In addition to the attack of natural energy, the various special effect bullets fired in this way will also add a strong electromagnetic impact, and the power will be doubled.

And if you want to upgrade to three or four stars, you have to redo the round pipe with special materials.

The best material is the Taiyi Star Magnet.

But this thing, even Jiang Xingwang, a senior forger, has only used it once in his life.

Now it's just a silver-gray round tube condensed with an ordinary magnet, and due to its own material, it is at most changed to an electromagnetic cannon barrel.

If the barrel is upgraded later, then there will be more tricks for the bullets.

Whether it is a "particle beam", or an "electron pulse", or even the strongest "space-based ion" of the Kunlun Federation, you can get started.

However, due to the amount of work in this area, the theoretical basis cannot be completed without thousands of drawings.

Therefore, Duanmu Mingcheng is only written as a conjecture in the last three design instructions.

Chen Qingshi and Jiang Xingwang breathed a sigh of relief after roughly reading the three hundred drawings.

If you can even give a detailed plan for this, then you are not a genius, but a demon.

When it was time to close the door, Zhang Chengcheng and his two younger brothers sorted out the weapons that had been repaired and maintained today, and went to hand over the errand.

As for how much rebate there is for the price, Chen Qingshi doesn't bother to care.

This forging shop is only used by him to practice, and the original intention is not to make money.

Take the Peach Blossom Demon to Jiang Xingwang, and rub dinner as always.

For the bright girl who suddenly grew up, Jiang Xingwang and Pei Xiuxiu were amazed.

When he returned home after eating, Chen Qingshi, who had stayed up for two days and one night, was about to fall asleep.

Habitually open the system interface before going to bed, click on all the sub-interfaces, and when he browses at will, he suddenly saw a word that made his eyes widen.

[Basic: The fifth layer of the Xuanwu Sutra / the highest fifty layer]

When did it happen?

Chen Qingshi glanced at the experience of the main interface, and 623 still hasn't changed.

He didn't sleep anymore, and clicked on the exclusive sub-interface of the "Xuanwu Sutra" again.

Sure enough, in the tip at the top, the answer was found.

[Turtles and snakes walk together, and they help each other. After all, it is the same as each other. Congratulations to the host for enlightening and practicing the mysteries of the Xuanwu Sutra, and raising the realm of the exercises to a higher level. 】

Why don't you feel it when you break through the exercises?

Obviously, when I used the system to improve the previous time, my body was so comfortable and my spirit was so refreshing.

Chen Qingshi glanced at the opinion of the system's prompt last night.

Oh, that's the time.

At that time, I seemed to be cooler and more comfortable, and I thought it was because of my senior sister's posture.

No wonder.

Chen Qingshi was still wondering, it was the first time for Senior Sister to let herself, who had always been reserved, be so uncontrollable, it turned out that there was also the bonus of the Xuanwu Sutra breakthrough and promotion.

Instantly understood everything.

I looked at the time, and it was getting dark.

Or......

Clockwork a message to ask the senior sister, are you free?

I just want to verify the mystery of this Xuanwu Sutra.

Nothing else.

But after thinking about the way she saw her sister away this morning, her snow-white legs without stockings were soft, and I thought it would be a few days.

edited a message of condolences and sent it to Senior Sister Yu.

Didi's voice rang out.

Back in seconds!

So, Chen Qingshi, who originally wanted to adjust his work and rest time, stayed up until three or four o'clock in the middle of the night again.

But at seven o'clock the next morning, he woke up on time.

The state of mind and transparent world formed by the fusion of advanced body strengthening and advanced meditation only need one or two hours of rest to completely recover from physical fatigue and mental exhaustion.

This is also the reason why Li Yuandao works during the day and practices at night.

This big guy can squint for an hour, and he can maintain the peak state for seven days and seven nights.

Chen Qingshi's cultivation is a little weaker, and he still needs to sleep for two hours for two days and two nights.

After the door is opened.

The Peach Blossom Demon also woke up, she was a demon fairy, and she used to use meditation instead of sleep, resting and cultivating to kill two birds with one stone.

It's just that she has recently been cut back to her weakest state, but it has allowed her to regain the joy of sleep.

This is where the busy day begins.

After a good rest, your productivity increases dramatically.

It took four days for Chen Qingshi to complete all the orders in the forging shop.

During this period, he also took the time to secretly comfort Senior Sister Yu.

Still in that small hotel, the two of them experimented with the mystical posture of the Xuanwu Sutra.

Probably because Yu Qinghe had also practiced the Tiger Deer, Bear and Ape Technique, some of his physique met the requirements. But this time, the green progress bar of the fifth layer of the Xuanwu Sutra was only a small step forward, and it did not have the huge benefit of directly breaking through the first layer.

However, Chen Qingshi is already very satisfied with this.

Sure enough, Li Yuandao didn't lie to him.

Chen Qingshi believes that as long as he persists in this kind of arduous practice, he will one day achieve great success.

After the condolences.

Chen Qingshi focused on transforming and upgrading his new weapons.

He dismantled the second half of the round tube that was originally just a rough implanted sand gun launcher, used 23 points of experience to krypton three copies of the atlas of the electromagnetic gun, and after thoroughly eating it, he used the file grinding wheel and other tools to make the track, accelerator, switch, and most importantly, the energy storage ejection ring one by one.

The second edition of "Era" is completed.

Leaving the customs is just another time for demons to go to sea, because the application to join the vanguard team was pressed by the star god general of the plague department, Chen Qingshi had no choice but to take out his anger with the demons who leaked into the tower.

He almost single-handedly swept away one-tenth of the demons on the third floor of the Ji Tower.

If you weren't very worried about Yu Qinghe, you ran to the second floor of Ji Tower responsibly.

I'm afraid that half of the demons in these three layers will be surrounded by him.

It has only been two months since I came to Yuwangguan.

Unconsciously, Chen Qingshi no longer felt the challenge.

The three most dangerous fronts of mankind are said to be good.

That's it?
