With more than thirty eyes on her eyes, Zhang Ping took a deep breath and walked up to the platform step by step.

When I passed by the operating table, I glanced at it and there were five large gears on it;

Among them, A, B, C, D, each stage is divided into three small gears;

There is only one S file, marked red.

At this time, the gear lever is hit in the position of ‘S’.

Zhang Ping was a little hesitant, but looking at the black muzzle of the "Celebrity Old Man" with his left hand, he still walked towards the steps with his head held high and stood still.

In an instant, the power of the source species hangs upside down like a waterfall, pouring into the body frantically, tough and arrogant, as if he wants to control himself.

Zhang Ping's heart trembled, the S-speed gear was a little fierce, and his body began to "disintegrate" uncontrollably.

Suddenly, the progress bar of the floating system activation in front of me is growing rapidly.

The body's absorption of source power is temporarily suspended, and the body's changes are controlled by oneself - not controlled by the system.

After the source power decreased, Zhang Ping felt that he could completely suppress the source power.

After more than ten seconds, the progress bar ends.

[Dingdong, Tech Tree evolution system is activated.

The initial evolution is about to begin, and it is expected to take 10 to 15 minutes.

Reminder: The system only provides assistance and guidance, and does not provide absolute protection.

Warning: Be sure to stay awake during evolution and do not fall into a coma or relax, otherwise it will be controlled by the source force.

Has it evolved?

whether】

"Yes!" Zhang Ping did not hesitate at all.

In an instant, the powerful source power flowed throughout the body; the body collapsed at a faster pace, but there was a strange vitality growing in the collapse, reshaping the body and eliminating diseases.

But the evolutionary process is not comfortable.

When disintegrating, there is pain of rupture of bones and pain of torn internal organs;

When reshaping, it is comfortable and warm, empty and confused, making people unable to help but want to relax.

Disintegration and reshaping are carried out simultaneously, and the taste is sour and refreshing.

The consciousness is weakened little by little in the torture.

But thinking about the consequences of the two teenagers in front of him, the horror of life and death allowed Zhang Ping to survive the crisis again and again.

I don’t know how long it took, but when Zhang Ping felt that he couldn’t hold on, he suddenly relaxed and exclaimed in his ears:

“It’s been a long time!”

"Has it succeeded?"

"It's successful! It seems different from the one in front."

"What's this? Is it a tin monster?"

"Look, he doesn't have a little **!"

“…”

Zhang Ping slowly opened his eyes and looked down at his body. Zhang Ping himself exclaimed.

At this moment, I suddenly became a... Iron monster!

Really tin body.

The whole body only has a silver-gray iron structure outside; the body is empty and there is a light red source power flowing in the body.

The body shell is still hollow, and only key parts such as joints are complete; the palms, arms, thighs, chest and abdomen are hollow iron structures.

There is a kind of air leakage everywhere...demeanor!

Inside her chest, there was a light red source species the size of egg yolk, which was slowly hovering, lazily sucking and spewing out traces of source power.

I touched my head and felt the thin piece of iron, which would sink a little harder.

"Hiss, it hurts a little. Touch, hearing, smell, etc. are actually intact. It's quite amazing."

[Dingdong, congratulations to the host for its successful evolution. Reward level 1 treasure chest draw once.]

[Dingdong, special reminder, physical hardness and integrity are directly related to defense, durability, combat effectiveness, etc.]

【Dingdong, I found that the absorbable source power is absorbed, did it absorb?】

Zhang Ping's eyes shone, his heart was ecstatic, and he also heard a burst of exclamations coming from around him.

He slowly turned his head and looked behind him. He first saw the old man with a look of vigilance, and his left hand turned into a silver-black pistol and pointed at him.

But Zhang Ping was obviously not crazy.

"Success!" The old man became excited, "Is it true that he did a great miracle? Your name is Zhang Ping, right?"

Zhang Ping nodded.

"Okay, keep moving forward." The old man said, opening the second control valve, but after thinking about it, he turned the gear to 'A-'.

He said to Zhang Ping, "You have completed the most difficult step, be careful next. If you feel something is wrong, tell me immediately; if you can't speak, wave your hand or make any moves."

"Okay." Zhang Ping walked forward and stood on the second ladder.

The surrounding source force increased by 50% - not only the quantity increased, but also the quality (energy level) also increased, which is approximately similar to current and voltage.

Zhang Ping absorbed greedily.

"carefree!"

The majestic source power is like an alternative vitality, and Zhang Ping can feel his body's rapid transformation.

The system's data is increasing rapidly.

After observation, Zhang Ping found:

The source power you absorb directly is injected into the experience article in item 1;

The source power absorbed by the system is left in the option of ‘source power’, which is equivalent to a warehouse.

However, during a few breaths, the system popped up again:

[Zhang Ping can evolve, estimated time: 5 minutes)]

"Evolution!" Zhang Ping did not hesitate.

[In evolution, the countdown is 5 minutes, please stay awake.]

This time there is no dangerous prompt, only a prompt to stay awake; obviously, the biggest crisis has passed.

Sure enough, this time the evolution was much easier, and Zhang Ping was able to clearly feel the changes in his body: the source species gradually changed from light red to light red, the strength began to increase, and the iron body began to be complete.

After 5 minutes, the evolution ends.

Zhang Ping opened his eyes and looked at his hands. This time he could feel a relatively obvious change:

strength!

Lift your hands gently, and the iron hands are relatively complete.

Life is more difficult since I came to this world; later I became ill and my health became worse and worse.

For the first time in eighteen years, Zhang Ping felt the power, enough power!

But the change has not stopped.

The system strikes again:

[Dingdong, Level 1 technology tree is opened, please light up the technology tree and start the perfect evolution path.]

Technology tree?

Perfect evolution?
