According to the current situation, unless Ye Feng has been using spiritual power to control the energy in his body. Otherwise, after absorbing the energy, the evolution box will automatically help him accelerate refining.

But Ye Feng's spiritual power was not enough to support it at all, and his long-term control evolved the energy that escaped from his flesh.

Of course, there is another way, which is to temporarily hand over the evolution box to another person for safekeeping. In this way, once the evolution box is far away from him, he will not be affected.

But this evolution box is Ye Feng's biggest secret, how can he casually expose it unless he has to.

As soon as he thought of this problem with the evolution box, Ye Feng felt a headache.

Suddenly, Ye Feng thought of a very critical question, "Can I control the opening and closing of this accelerated refining function of the evolution box independently?" ”

This alien thing can't even have a switch!

As soon as he thought of this, Ye Feng couldn't help but pick up the evolution box and look at it carefully.

Speaking of which, since he got the evolution box from Ye Feng, since he has been dealing with the apocalyptic crisis, he has no time to study this thing properly.

After taking 90 pieces of evolution meat, Ye Feng's eyesight was very good, and even with the help of the faint starlight that came through the window, he could see the evolution box in his hand clearly.

The box looked like one of those metal lighters, but of course the hundreds of animals carved on it came to life, making it look more like a work of art.

It's a pity that Ye Feng looked around several times, and even reached out to touch every animal carved on it, but he couldn't find anything like a switch.

"The switch designed by the aliens should be very clever, will it rotate like a Rubik's cube?" Ye Feng thought of it in a big way.

But unfortunately, it turns out that he thinks too much.

Even if he tried his best, he couldn't move this metal box in the slightest, it seemed that this evolution box was made of a whole piece of special metal, and it was basically one.

Ye Feng helplessly took the evolution box and pondered for a while, and suddenly thought of a possibility again, "This evolution box, could it be energy controlled?" ”

Thinking of this evolution box, which could absorb the energy in the ability flesh, the more Ye Feng thought about it, the more he felt that this was the most likely.

As soon as he thought of it, Ye Feng immediately mobilized a wisp of true qi from the dantian, carefully controlling it to approach the evolution box.

As Ye Feng guessed, the true qi in his body easily entered the evolution box.

However, before Ye Feng could be any happy, in the next moment, the evolution box suddenly emitted a strong fluorescence.

At the moment when this fluorescence emanated, Ye Feng suddenly felt a huge amount of energy gushing out of the evolutionary flesh in his body, instantly pouring into his limbs.

This sudden energy made Ye Feng's face instantly red.

If it weren't for his quick reaction, which immediately withdrew the true qi injected into the evolution box, and used the Yellow Emperor's Internal Scripture Exercises to suppress the energy in his body with all his might, I'm afraid there would be something wrong this time.

"This ...... What the hell is going on? After controlling the energy in his body, Ye Feng muttered with palpitations.

However, in Ye Feng's last life, he had experienced so many major events, and his heart had long been tempered calmly, and he quickly calmed down, carefully recalled what happened just now, and began to think.

"Judging from the situation just now, True Qi can also activate this refining ability of the evolution box, and the effect is even better."

Judging by Ye Feng's spiritual power induction, if the energy in the evolution flesh is used to activate the evolution box, it can increase the speed by about 10 times.

However, if True Qi is used, then this speed will be able to increase to 50 times that of a terrifying one.

"It seems that the effect of this evolution box, the energy injected is different, and it will also produce different effects." Ye Feng came to this conclusion, and at the same time, he was secretly surprised in his heart.

If the effect of the evolution box is stimulated by the true qi, and the refining speed reaches 50 times, then Ye Feng can also double this speed when combined with the Yellow Emperor's internal scripture exercises. That's exactly 100 times.

It is no exaggeration to say that for others, the problem of slow refining and evolution of flesh will not exist in Ye Feng at all.

The only thing that restricts Ye Feng's ability to improve his strength now may be how to hunt zombies of the same level.

After all, after Ye Feng became a second-order evolutionary, he would need second-order evolutionary meat in order to improve his strength.

Of course, this is only the benefit of improving strength, and what surprises Ye Feng the most is that he can use this super fast refining speed to greatly increase his continuous combat ability.

It is completely conceivable that as long as Ye Feng swallows the evolution meat, and then activates the evolution box and cooperates with his own exercises, the 100 times refining speed can fully support Ye Feng's high-intensity consumption.

This was enough for Ye Feng to be able to perform the Spring and Autumn Sword Technique, or the Soul Destroying Needle many times during a battle.

Of course, after a period of surprise, Ye Feng was a little difficult, because he still hadn't solved the problem of how to deal with the evolution box.

"By the way, since true qi can be injected into it, can spiritual power also be injected?" Ye Feng suddenly thought of another possibility.

After thinking of this possibility, Ye Feng immediately began to try.

As soon as his mind moved, spiritual power rushed out of his mind, and almost instantly, it enveloped the entire evolution box. The animals and patterns carved on the evolution box were all visible under Ye Feng's spiritual power exploration.

And the next moment, Ye Feng's spiritual power began to seep into the evolution box.

"Buzz!"

Ye Feng only felt a buzzing in his head, and his consciousness seemed to be blurred, and the next moment, Ye Feng was instantly stunned.

Because he found that his consciousness actually came to another space, this space was about one meter long, wide and high, but it was surrounded by a hazy mist.

Even with Ye Feng's knowledge, he didn't understand what was going on at all.

However, at this moment, a stream of information directly entered his mind through Ye Feng's spiritual power.

Ye Feng only felt a confusion in his mind for a while, and then he had some more memories, and these memories were actually all about the function and usage of this evolution box.

Ye Feng didn't expect that the secret of the evolution box would be presented in front of his eyes in such a way.

And looking at the memories in his mind, Ye Feng suddenly knew that this evolution box had a total of three functions.
