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

But Ye Feng's mental power was not enough to support him. He controlled for a long time and 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, after the evolution box is far away from him, he will not be affected.

But this evolution box is Ye Feng’s biggest secret. How could he be exposed without any last resort?

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

Suddenly, Ye Feng thought of a very critical question, "Can the acceleration refining function of the evolution box be controlled independently by me to turn it on and off?"

This alien thing will never have a switch!

When Ye Feng thought of this, he couldn't help but pick up the evolution box and looked at it carefully.

Speaking of which, since Ye Feng got the evolution box, he has always been dealing with the crisis of the end of the world, and he has no time to study this thing carefully.

After taking 90 pieces of evolutionary meat, Ye Feng had a good vision. Even with the help of the faint starlight coming in from the window, he could see the evolution box in his hand clearly.

This evolution box looks like a metal lighter, and of course, because the hundreds of animals carved on it are lifelike, it looks more like a work of art.

Unfortunately, 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 aliens should be very clever. Will it rotate and start like a Rubik's Cube?" Ye Feng thought with a big brain.

But it was a pity that he had thought too much.

Even if he used all his strength, he could not carry the metal box at all. It seemed that this evolution box was cast from a whole piece of special metal and was completely integrated.

Ye Feng held the evolution box helplessly and thought for a while, suddenly thought of a possibility again, "Can this evolution box be controlled by energy?"

Thinking of this evolution box, it can absorb the energy from the supernatural flesh. The more Ye Feng thought about it, the more he felt that this was the greatest possibility.

When he thought of it, Ye Feng immediately mobilized a wisp of true energy from his dantian and carefully controlled it to approach the evolution box.

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

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

At the moment when the fluorescent light emitted, Ye Feng suddenly felt a huge energy rushing out of the evolutionary flesh in his body, which instantly rushed into his limbs and bones.

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

If he hadn't reacted quickly and immediately retracted the true energy injected into the evolution box, and used the Huangdi Neijing technique to suppress the energy in his body with all his might, I'm afraid there would be something wrong with this.

"This...what is going on?" Ye Feng murmured with lingering fear after controlling the energy in his body.

However, after Ye Feng experienced so many major events in his previous life, his mind and nature had been tempered and calm. He soon calmed down, recalled what had just happened, and began to think about it.

"According to the situation just now, the true qi can also be activated, and the refining ability of the evolution box is better."

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

However, if you use true qi, then this speed will be increased to 50 times that of terrifying.

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

If you use the true qi to stimulate the effect of the evolution box, and after the refining speed reaches 50 times, and then Ye Feng can double this speed, that is, a full 100 times.

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

The only thing that restricts Ye Feng from improving his strength now may be how to hunt zombies of the same level.

After all, after Ye Feng becomes a second-level evolver, he needs second-level evolutionary meat to improve his strength.

Of course, this is just the benefit of improving strength. What surprised Ye Feng the most was that he could 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 evolutionary flesh and then activates the evolution box and cooperates with his own martial arts, the 100-fold refining speed can fully support Ye Feng's high-intensity consumption.

This is enough to allow Ye Feng to use the Spring and Autumn Sword Technique or the Soul-Destroying Needle multiple times during a battle.

Of course, after a burst of surprise, Ye Feng became a little troubled again because he still didn't solve the problem of how to deal with the evolution box.

"By the way, since all the true qi can be injected, is mental power okay?" Ye Feng suddenly thought of another possibility.

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

As soon as he thought, his mental power surged out of his mind, and almost instantly enveloped the entire evolution box. The animals and patterns carved on the evolution box were revealed under Ye Feng's mental power exploration.

The next moment, Ye Feng's mental power began to penetrate into the evolution box.

"Buzz!"

Ye Feng only felt a buzzing sound in his head, and his consciousness seemed to blur. The next moment, Ye Feng was shocked instantly.

Because he found that his consciousness actually came to another space, the length, width and height of this space were about one meter, but there was a hazy fog around him.

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

But at this moment, a stream of information was directly transmitted into his mind through Ye Feng's mental power.

Ye Feng felt confused in his mind, and then he had more memories. These memories were all about the functions and usage of this evolution box.

Ye Feng didn't expect that the secret of the evolution box would be presented to him in this way.
