Adding higher-level knowledge for integration skyrockets the experience cost.

Take basic knowledge integration as an example. Adding an advanced piece of knowledge costs an extra 50,000 experience, and the consumption of basic knowledge doubles from 5,000 to 10,000. By analogy, integrating advanced knowledge with advanced knowledge also doubles the consumption.

"Confirm integration!"

Han Xiao stared intently at the panel, hoping to maintain his recent luck!

[Integration successful! Congratulations, you have developed the Magnetic-Controlled Metal Extension Armor!]

Han Xiao was overjoyed.

What did I tell you? My luck stat is really high lately!

But Han Xiao glanced at his Luck attribute, and his smile gradually disappeared… How long will it take to make up for the Luck used this time?

This blueprint was his goal. This thing was not something he should have at his level. It was a defense equipment that exceeded the level and could raise his safety level by one… no, two levels!

Of the 300,000 materials, 250,000 were prepared for this blueprint.

Advanced-level blueprints are several times more difficult than basic blueprints. Even if he understood the blueprint and the knowledge, Han Xiao spent an hour sorting out the content of the blueprint. He calculated the manufacturing time and showed a wry smile. It would take at least three days of non-stop work!

Without saying anything, Han Xiao threw himself into the difficult manufacturing work.

…

Three days later, the door of the workshop opened, and Han Xiao, who had been in seclusion, walked out, his eyes dull, with a pair of dark circles that looked like he'd gone through tribulation. He had a blank look on his face, as if asking, "Who am I? Where am I? Who's hitting me?"

As soon as he turned on his phone, Li Ya Lin called, complaining.

"Han Xiao, I haven't been able to reach you these past few days. There are dozens of agent orders piled up, and they're all urging you to deliver. You can't take the deposit and not do anything. I guaranteed you with my reputation. And, and, you promised to customize a piece of equipment for me last time, don't forget it. By the way, the higher-ups assigned us a mission yesterday. We're leaving for Hai Xia in ten days. The captain held a meeting yesterday, and you weren't there. He was very angry. You have to be careful when you see him next time…"

Han Xiao's eyelids were fighting, and he didn't want to do anything but sleep. He rolled into bed with a quilt, and as soon as his head hit the pillow, he fell asleep like a dead pig, no matter how much Li Ya Lin chattered on the phone.

"Hey, hey, hey… why aren't you talking… Damn it, I haven't settled the score with you for touching me last time…"

…

What's the first thing you do when you get up?

Open your eyes?

No, no, no, it's going to the bathroom.

Early the next morning, Han Xiao drifted to the bathroom like a sleepwalker. After relieving himself in a daze, he finally woke up completely, shuddered, felt refreshed from top to bottom.

Han Xiao yawned, mechanically brushed his teeth and washed his face, opened the door of the repair shop with a pair of dead fish eyes, and went straight to the kitchen. He squeezed Lü Qian away, and under Lü Qian's frantic hammering with her small fists, calmly finished her breakfast.

Under Lü Qian's resentful gaze, Han Xiao leisurely walked back to his workshop.

Old Man Lü stroked his bald head and sighed, "Just like when I was young, so unrestrained."

"I'm going to change the lock, ahhhh—"

Old Man Lü pondered, "Perhaps this is young people's love."

"That's not it!!!"

Lü Qian roared like a tigress from the east river.

…

Han Xiao returned to the workshop and took out the results of his three-day seclusion, a small box of fish scale-like fragmented metal flakes, black with a hint of dark blue.

No matter how you look at it, this box of metal flakes has nothing to do with the word "armor," but this thing is indeed Magnetic-Controlled Metal Extension Armor… incomplete.

Han Xiao took a deep breath and placed his palm above the box of metal flakes, only three centimeters apart.

He activated the Qi (energy) in his body, and a tingling magnetic Qi covered his palm.

A magical change happened!

The silent fish scale metal flakes suddenly trembled and automatically gathered, being attracted to Han Xiao's palm, like lively swimming fish moving on Han Xiao's arm.

"Shape." Han Xiao said in a low voice, and the Qi flowed through his entire arm. These metal flakes spread out in the blink of an eye, turning into a light, fish scale-like armor, seamless and neatly arranged, without any overlap.

The metal flakes seemed to be attached to the arm, but they were actually suspended a few millimeters away from the skin, controlled by the magnetic field repulsive force, without affecting movement.

Han Xiao drew out the folding Tyber warblade and slashed hard on the fish scale armor. With a crisp clang, there was no spark at all, and the armor was undamaged.

"Excellent defensive performance!" Han Xiao's face was joyful.

[Magnetic-Controlled Metal Extension Armor (Incomplete)]

[Type: Extendable Full Body Bulletproof Vest]

[Quality: Green]

[Basic Attributes: Defense 75, Total Expanded Area 0.2 square meters (approximately equivalent to the entire back), Durability 1600/1600]

[Equipment Requirements: Magnetic Attribute Qi, Intermediate Mechanical Affinity]

[Effect: Through Qi (magnetic) induction, the magnetic field is used to move the metal flakes of the armor, roaming the whole body, and armor can be formed in any part, maintaining the shape of the armor requires 10 Qi/minute]

[Additional Ability: Super Toughness - Has high temperature, radiation, and penetration resistance, can effectively protect the human body, and is not easy to wear.]

[Additional Ability: Repulsive Fit - Damage received by the user is reduced twice, reducing damage by 20~30 points.]

[Additional Ability: Special Magnetic Field - When used, a highly conductive magnetic field will be formed on the user.]

[Note: Friendly reminder, please do not use this equipment in thunderstorms.]

Equipment that requires Qi is called Esper Armament. This magnetic-controlled extension armor is an exclusive equipment for mechanics!

Esper Armament is a large category, characterized by Qi driving. Generally speaking, the effect is much stronger than ordinary mechanics of the same level.

The raw material for these metal flakes is a highly conductive and magnetic metal, and it is not an alloy. It is a very rare metal ore, very expensive. Even the Thirteenth Bureau doesn't have much stock. Han Xiao spent 250,000 to create metal flakes that could cover the entire back. The core of this equipment is [Advanced Material Synthesis]. The application of electromagnetism is relatively simple, so [Basic Electromagnetic Principle] only needs two levels to meet the requirements.

The principle is to fuse the magnetic fields of these magnetic-controlled metal flakes to form a magnetic chain. Materially, they look separated, but the magnetic field can be combined at any time. This is one of the principles of turning into armor instead of other messy shapes. The most difficult part is the material synthesis of these metal flakes. The work is heavy, tedious, and repetitive. It took him three days and exhausted him physically and mentally. However, this blueprint is one of the less technically difficult advanced blueprints.

Han Xiao's current level, knowledge, and technology are not high enough, so he can only barely manufacture advanced equipment, and it is incomplete.

Completing this equipment gave him 40,000 experience, more than manufacturing the Generation 1 Ranger.

Han Xiao controlled the magnetic-controlled metal armor to roam his body, which was a bit jerky, but he quickly became proficient, and a sense of familiarity surged into his heart.

Many high-level equipment requires practice to use normally. This is a manifestation of the level of operation. Han Xiao has enough driving experience and is an expert.

With the magnetic-controlled metal armor, his safety is greatly guaranteed. Moreover, the magnetic-controlled metal armor is very concealed. When not in use, it is stored in a special small box with holes and hung on the back of his waist. With the cover of clothes, it will not be discovered.

Secret, easy to use, and portable, Han Xiao will not easily reveal his trump cards, even to his own people. Who knows if his own people will become enemies one day. He always believes that mild paranoia and suspicion are caution.

Ranged, melee, movement, and defense, these four aspects are all taken care of, leaving only art.

Han Xiao already had an idea. The Thirteenth Bureau's bombs were enough, so he didn't need to integrate new blueprints, just some simple modifications.
