[Upgrade Plan 1 - Mechanical Double Rings: Integrate the double rings of steel into the remains of some alchemy machinery, so that it has a certain mechanical structure, greatly enhances its binding ability, and has a certain self-repair ability. Level 4 supernatural species cannot break free from the constraints, and the upgrade consumes 180 survival points]

[Upgrade Plan 2 - Indestructible King Kong: Incorporating a shell with a very high degree of cherishing, so that the steel double rings have the characteristics of Indestructible King Kong, and they cannot break free from the level 7 super type. Upgrade consumes 250 survival points.]

[Upgrade Plan 3 - Fusion Evolution - Mechanical Prison: At the same time, integrate the alchemy machinery and the Indestructible shell, greatly modify and optimize the binding structure, so that it is enough to bind the level 7 supernatural species, and upgrade to consume 300 survival points.]

The third one is the one. Fusion evolution is always the strongest and most expensive option among many upgrade solutions!

If you want to choose, choose the most expensive one!

Chen Changan carefully studied the third upgrade plan and found that only upgrade plan three has the power to bind the level 7 extraordinary species!

The effect of the Mechanical Prison is almost the same as the silver quality. Even if it is a real silver-level treasure, Chen Changan probably can only bind the 8th level extraordinary species, which is comparable to the fourth-level magic circle.

"It's decided it's you, Fusion and evolution! The Mechanical Prison!"

Chen Changan threw the remains of a large number of alchemy creatures and the indestructible shells to the double rings of steel.

With the crew members stunned, Chen Changan quickly paid 33 survival points, and a green light of love suddenly shot out!

Wang Fugui took three steps in a row and said in shock:

"Boss, what happened?"

The other crew members were also full of incredible expressions, and an unknown fear lingered in everyone's hearts.

Chen Changan chuckled and said:

"You can try to send what I'm doing now to the forum."

All the crew realized that this green light might hide Chen Changan's major secret, and hurriedly said:

"No, we will never reveal your secrets, boss!"

Chen Changan looked unfathomable, silently waiting for the upgrade of the green light to continuously transform the steel double ring bound structure, and said with a smile:

"Try it."

Just try it and die!

The crew members thought bitterly, but Wang Fugui was the number one fan among the seven, and gritted his teeth and said:

"Boss, since you let us do it, you must have your ideas, I'll try it first."

Wang Fugui opened the Deep Sea Forum and tried to sort out Chen Changan's actions at this time into a post and try to post them.

But when things came to an end, Wang Fugui found that there seemed to be another force in his heart, preventing the secret from being leaked, and panicked:

"Boss, I can't send it out at all!"

Chen Changan smiled and said with a smile:

"Because you have signed a confidentiality contract with me, in this extraordinary world, words are of course powerful."

Especially after I upgraded to light blue quality... Of course, Chen Changan did not say the second half of the sentence.

"There is such an operation?" Wang Fugui widened his eyes, then relaxed and said, "It's good, we are afraid that when will you accidentally leak your secret?"

"Yes, yes, we will never reveal the boss's secret!"

"Boss, don't worry."

Many crew members expressed their loyalty, but their words were blank. Chen Changan believed in a contract with extraordinary power.

Confidentiality contracts have undergone two extraordinary evolutions and have the ability to force confidentiality.

No matter in any way the contractor uses to disclose the secrets of Chen Chang'an and Fei Xiang's Henan people [including but not limited to text, language, body language, puzzles, etc.], they will be dissuaded by the power of the God of Contract.

If Wang Chenghuan and others want to break through the constraints of the God of Contract, they must at least reach the level 4 extraordinary.

By the time they reach the level of the mid-level extraordinary species, with Chen Changan's growth rate, they can long ago upgrade the contract to dark blue, thereby increasing the boundary range to a higher level.

This is the real reason why Chen Changan is fearless!

It is also the confidence to continue to recruit more crew members in the future!

Chen Changan quietly looked at the mechanical prison in the green light.

At this time, the remains of the alchemy creatures had been swallowed up by the double rings of steel, turning into a more sophisticated restraining structure.

From feet to legs, from waist to chest, from neck to head, every part of the body is bound by various mechanical structures.

In the exquisite mechanical structure, exquisite mechanical structures are reflected everywhere, and even scientific researchers in the field of mechanics research will find it difficult to find any flaws.

But, not enough!

This is just the effect shown by the upgrade plan!

After a long wait, Chen Changan finally waited until the Indestructible shell of the Vajra was gradually melted by the upgraded green light, turning into gold liquid, and melting into the mechanical prison bit by bit.

Buzzing!

A roar sounded!

When the golden liquid melted into the Mechanical Prison, everyone heard a roar of machinery, and they all turned their eyes to the Mechanical Prison that was about to be completed.

Chen Changan looked at the mechanical products in the green light with anticipation and thought:

"How can I feel that the Mechanical Prison will directly break through two realms and enter the silver quality?"

brush!

The upgraded green light suddenly disappeared, and a brand new steel creation suddenly appeared in front of everyone.

Chen Changan tried to touch it, and the system immediately sent a congratulatory message:

"Congratulations, you have obtained the Mechanical Prison!"

【Mechanical Prison】

Quality: Silver (unstable, will be downgraded to dark blue after eight hours)

Introduction: Special items specially customized to restrain the fourth-level magic array - resist wind rings. They have single functions and accumulated functions, but can effectively bind the creatures on both sides of the double rings to avoid separation due to resisting the repulsive force of the wind rings.

Effect 1: Extreme constraint

A steel creature that increases the bonding effect to the extreme, even a level 7 supernatural species, once locked into the ring, cannot break the double ring and escape in a short time.

Effect 2: The King Kong is indestructible

The material is incorporated into the material, making the material toughness and hardness reach silver quality in all aspects and cannot be easily destroyed. However, ordinary steel cannot withstand the characteristics of the characteristics of the indestructible diamond. At most eight hours, the characteristics of the indestructible diamond will disappear.

Evaluation: It’s extremely useless! But in a sense, it has reached the extreme of the restrictive field!

"Finally, the last pass of evil nuclear weapons has been broken!"

Chen Changan showed joy on his face and was stroking the powerful mechanical prison excitedly. He just needed to lock himself and the filthy sea spirit into it and could break through the level 4 magic circle - resist the restrictions of the wind ring!

But at this moment, Yang Tianhua's expression suddenly stopped behind him.

His fingers trembled slightly, and he could not believe the content that was circulating in the Deep Sea Forum at all, but he had to believe it and had to believe it!

"How could this happen... It's obviously the 29th today~"

Yang Tianhua walked slowly to Chen Changan, and said with a hoarse voice:
Chapter completed!
