If you add a push force such as levers, ropes, explosives, etc., it should be faster. However, if you rely on the mechanism, the materials and structures that can withstand at twice the speed of sound, I'm afraid it's still a little difficult to do now, thinking of this, Zuo Zhicheng still gave up the plan to continue to accelerate, anyway, the explosion arrow at twice the speed of sound is already very powerful.

What's more, as long as this kind of explosive arrow Zuo Zhicheng stores enough in the imaginary space, he can use it as he wants when fighting.

You must know that the explosion of the triple transcendent martial arts like he just now completely squeezed every inch of his body's potential, extremely depleted the body, and even had a great burden on blood vessels, bones, and muscles.

Like the shot just now, even if he may use it 5 or 6 times in an hour, if he exceeds it, he will severely damage his body and leave sequelae.

But now through the mouth of the Yellow Spring and the imaginary space, he is equivalent to storing his usual combat power in advance, and then bursting out in an instant during the battle.

If he had the mouth of the Yellow Spring when he was fighting with the Queen of the Wind, and there were dozens or hundreds of explosive arrows with double sonic speed in the imaginary space, he would not be so wolf.

With an explosive arrow with double the speed of sound, his destructive power may not be as good as that of Tianhao Taiguang God Thunder Fire, but his penetrating power is stronger. For example, when encountering things like sand, water mist, mud and dust, the 10√ Tianhao Taiguang God Thunder Fire will lose a lot of energy due to heating obstacles, scattering and refraction, etc., but the double-speed explosion arrow can consume very little kinetic energy to penetrate these.

Subsonic steel needles, explosive arrows at double sonic speed, these are just the beginning.

According to the needs of different scenarios, Zuo Zhicheng will go from weak to powerful destructive power, and store different attacks in the imaginary space, making himself a super humanoid arsenal and a humanoid weapon platform.

Then he walked back to the carriage. Opening the mouth of the Yellow Spring, he sucked the explosive arrows on the carriage into the imaginary space one by one.

Qingyueqiu, who saw this scene, also opened her mouth wide, although she saw Zuo Zhicheng exert her strength in an instant, but she left her field of vision all of a sudden, and she didn't see what was going on, but now she can see it clearly.

But she was just surprised. But she didn't ask anything, because she didn't want to embarrass Zuo Zhicheng. As early as a year ago, Zuo Zhicheng's insight, experience and methods that she showed again and again had already let her know that the other party knew a lot of Taoist techniques, and she was still cultivating to become stronger.

But she didn't once slack off anyone.

Seeing that Zuo Zhicheng sucked all the explosive arrows into the imaginary space in a blink of an eye, he counted them, and there were about a thousand arrows. With these thousand explosive arrows alone, I don't know how many craftsmen it will take. How much material and how much time it takes to make zuò.

After all, this kind of explosives is very dangerous, and with contemporary technology, there is still a great failure rate.

If it weren't for Zuo Zhicheng to pull Zhu Yuwen to be the big boss and sponsor him. Let's not talk about whether he has a way or not, with his own financial resources alone, I'm afraid it will be difficult to make up so much.

Next, I saw the bone spurs behind Zuo Zhicheng shake violently again, and the triple transcendent martial arts broke out again, holding an explosive arrow in one hand. When the speed reaches its peak, it stabs out like a spear. Finally, it is stored in the imaginary space.

Even with Zuo Zhicheng's body, he would have to rest after five consecutive such efforts, which means that he could create a maximum of five double-sonic explosive arrows in an hour, and if there were a thousand, it would take him two hundred hours to load them all.

Qingyueqiu stood aside, and saw Zuo Zhicheng's appearance of running around from beginning to end. Her gaze moved, and she seemed to see a little bit of the doorway.

When he saw Zuo Zhicheng stop, he walked over. Seeing that the other party was panting, and there was green blood flowing out of the corners of her mouth, her eyes tightened: "Are you okay?" ”

"It's fine. Just rest for a while. With that, Zuo Zhicheng brought back all the other things left on the carriage, and he planned to complete the rest in the real room, and then go out once an hour to generate double-speed explosive arrows.

"What about the other two," he asked. ”

Qingyueqiu said: "The quarry has been decided, but the size you asked for is too large, although there are no other requirements, but I am afraid it will take two months to complete."

As for the Tiger Wolf Army, the target has been selected, which is the Taiming thieves in the northwest, and that group of bandits is about 2,000 people. They'll also have to scout and make a plan, and they'll leave in about a week, and they'll let you know when the time comes. ”

Zuo Zhicheng thought for a while and said, "Let them be two weeks late, and I will insert a few people into it." ”

"Yes." Qingyueqiu nodded: "However, how did you get Zhu Yuwen to agree to these things?" I'm afraid it's not just as simple as accepting one student. ”

"I promised him something, and on top of that, I'm going to open a school."

"What?" Qingyueqiu said with some surprise: "School? ”

"It's similar to the sect, teaching some simple martial arts and Taoism can be regarded as helping Nanwan cultivate some talents." Zuo Zhicheng said: "However, the preparation process will take another year or two, which is not a near-term plan, and Zhu Yuwen and I are only the founders." For specific details, you can ask your dad. ”

Qingyueqiu didn't speak, but he became more and more curious about the school Zuo Zhicheng was going to open.

"What will it look like?"

……

In the hall, this time Zuo Zhicheng was not waiting for Ji Nanxian. Now, in addition to the one-hour class every day, he only teaches Ji Nanxian and Sun Feibai for one hour a week.

Today is Sun Feibai's first class.

"You should already know how special you are, and you know that you have such a thing as a fate, right?"

"Hmm." Sun Feibai said with some expectation: "I heard Brother Xu say some common sense. But I still don't understand what my life is capable of. ”

Zuo Zhicheng said lightly: "Your life cong is called Chiguan, he doesn't have many abilities, there is only one kind, that is, to make everything burn." ”

"Burning everything?" Sun Feibai silently repeated this sentence.

Zuo Zhicheng nodded: "Burning everything sounds simple, but it's actually very complicated. Because air, water, stones, raindrops, the Yangtze River, the great river, the hurricane, the thunder, all things contain too many concepts.

And you can burn all these things, even yourself, are included.

So your abilities are dangerous, and you have been bound by common sense since you were a child, which is actually an instinctive self-preservation. I'm going to teach you how to control and use this ability, and until I'm sure you're in full control, you can't use it without my command. ”

Zuo Zhicheng looked at Sun Feibai in front of him, and said secretly in his heart: "If you learn fast enough, you can help me a lot." ”

Just when Zuo Zhicheng was thinking so, Sun Feibai on the opposite side suddenly snapped his fingers, and saw a small cluster of flames jumping out of his index finger, like a small person, not jumping and dancing.

He grinned and said, "My lord, is this considered complete control?" ”

Zuo Zhicheng's brows furrowed, even if it was him, he couldn't help but feel a little jealous in his heart at this moment. (To be continued......)
