Under One Person: The Puppet Immortal in the Tang Sect

He looked at Cui Ming, his gaze direct.

"Master Cui, this mechanical arm... how much of my strength can I recover?"

"It depends on how well you adapt."

Cui Ming's expression remained normal.

"If we only seek basic functions, with Brother Lü's abilities, he can reach 70-80% of the average person's level in less than a month."

However, to unleash the full power of the Ruyi Jin, a longer period of training is required.

In fact, Brother Lü, if you adapt well, you might even unleash greater power. But this all requires you to adapt to new techniques for generating force.”

"Surpass?"

Lu Ci couldn't help but speak up.

"Master Cui, is that really true?"

"nature."

Cui Ming was full of confidence.

"The flesh and blood body has its limits; bones will break and muscles will tire."

"The alloy frame of the mechanical arm is stronger, and the upper limit of its output can be adjusted by the energy core."

"Theoretically, you could unleash even greater power if you could adapt. But..."

He paused.

"But what?"

Lü Ren couldn't wait.

"But this means you have to change your instinctive exertion that you've developed over decades."

Cui Ming said.

"The variations in strength and softness of Ruyi Jin are based on the design of the human body structure."

"If it's replaced with a mechanical arm, the way the joints move and the path of force transmission will be different."

"You need to recreate a set of energy transfer techniques suitable for new arms."

Lü Ren remained silent.

The only sound in the hall was the occasional crackling of the charcoal fire.

After a long while, Lü Ren looked up.

"I accept."

"Ren'er!"

Lü Chang hesitated, as if he wanted to say something but then stopped.

“Father, I understand the risks.”

Lü Ren looked defiant.

"But if I don't use this mechanical arm, I, Lü Ren, will be a cripple from now on."

"I can't let my younger brother bear the entire burden of the family if I fail to master the Ruyi Jin (a martial arts technique)."

He stood up, his empty sleeves fluttering slightly in the wind.

"Master Cui, when can we begin?"

"We need to prepare materials and design a specific plan."

Cui Ming stared into Lü Ren's eyes.

"I will bring my tools in three days. The surgery requires a quiet environment, preferably in a private room."

"it is good."

Lü Ren nodded.

“I will be ready.”

……

That night, Cui Ming drew up design plans in a guest room arranged by the Lü family.

Sword Puppet Nameless stood in the corner, motionless like a statue.

Its existence was known only to Cui Ming; the Lü family regarded it as a puppet that Cui Ming carried with him and did not inquire further.

Why are you helping the Lü family?

An unnamed voice echoed in Cui Ming's mind.

After the modification, it still retains some thinking ability, but all judgments prioritize Cui Ming's interests.

Three reasons.

As Cui Ming marked the dimensions, he responded in his mind.

"First, the Lü family wields considerable influence in the world of supernatural beings in the Eastern Kingdom; doing them a favor would be entirely beneficial."

"Secondly, the robotic arm technology needs practical testing, and Lü Ren is a suitable test subject. Moreover, with the Lü family as a benchmark, things will undoubtedly go more smoothly in the future."

'third……'

He stopped writing.

What is the third?

Third, I need the Lü family to be on my side at some point in the future.

Cui Ming continued drawing.

"The situation in the Eastern Kingdom is becoming increasingly chaotic; the Divine Strategist Alliance alone is insufficient. The Lü family values ​​loyalty and righteousness; today I have saved Lü Ren, and one day they will repay me with their lives."

The nameless man stopped asking questions.

The sound of footsteps of the night patrolmen could be heard outside the window, gradually fading into the distance.

Cui Ming finished the last annotation and put away the drawing.

Three days later, the surgery was performed in a secret underground chamber of the Lü family.

The sealed room was thoroughly disinfected, and the four walls were covered with soundproof talismans.

On the central stone platform, Lü Ren lay naked from the waist up, with local anesthesia applied to the severed arm.

Cui Ming laid out the tools one by one.

Next to it stood a mechanical furnace about half a person's height, inside which alloy materials were being smelted.

The Nameless Sword Puppet provides assistance, its twelve flying swords hovering in the air with their tips pointing downwards, ready to deal with any unexpected situations.

"start."

Cui Ming took out numerous mechanical arms from the Devouring Pouch and mounted them on his back. The mechanical arms brushed against the cross-section of Lü Ren's severed arm.

Beneath the skin, nerve bundles curl up like withered tree roots.

He first used a carving knife to cut open the surface tissue to expose the main nerve branches.

Then, the nerve endings are picked out with a connector pin and connected to the test circuit.

To ensure the surgery proceeded smoothly and to prevent Lü Ren from experiencing excessive pain that could lead to failure.

Cui Ming used his own Dan Shi power to penetrate into Lü Ren's body, numbing Lü Ren's nerves and preventing the pain from being transmitted back to Lü Ren's brain.

Even so, Lü Ren's body still trembled slightly instinctively.

"pain?"

"It's numb, and there are some strange twitches."

Lu Ren answered with his eyes closed, sensing his own condition.

"That's normal. It means your nerves are being activated."

Cui Ming continued the surgery without telling the truth, and continued to observe the reaction.

After confirming that the nerve activity was intact, Cui Ming began implanting the neural connection device.

It was a metal disc about the size of a bowl, with its surface covered in micropores.

Cui Ming attached it to the fracture surface and fixed it with bone screws.

Next, the nerve endings were connected one by one to the interfaces on the back of the disc.

Each time he received a needle, Lü Ren's body would twitch.

Cold sweat seeped from his forehead, but he could only feel his body twitching, not pain.

He knew in his heart that Cui Ming must have shielded him from the pain, otherwise he wouldn't have been able to feel so relaxed.

Once the neural connection device was installed, Cui Ming began the encapsulation process.

He used bio-adhesive to cover the joint, forming a sealing layer.

This gel will eventually integrate with the skin and flesh, becoming part of the body.

Next is the main body of the arm.

The furnace is turned on, and the molten alloy flows into the mold.

After cooling, Cui Ming took out the formed arm skeleton.

Its structure is similar to that of the Nameless Sword Puppet, but it is more slender and closer to human proportions.

He connected the frame to the base and locked the latches.

The energy circuit began its self-check, and pale blue light patterns spread along the skeleton.

From shoulder to wrist, and then to the five fingers.

The fingertips are slightly bent, then straightened.

"Try moving your index finger."

Cui Ming prompted.
