High-level martial arts: Contract cashback, invincible starting from the Zerg.

The headquarters of the Qian Yuan Shangcheng Military Command is located in the Cangxuan Mountains.

The entire mountain range is covered with defenses from the Great Xia Kingdom, reaching up to near-Earth orbit and penetrating 8 kilometers into the earth's surface, with a total defense radius covering a 120-kilometer radius around the base.

Since its construction, no hostile force has ever been able to break through its outer defense perimeter.

Therefore, the Cangxuan Fortress, where the Qianyuan Upper City military headquarters is located, is also the safest place in the Great Xia Kingdom.

"Our base has thirty-six 'Mysterious Thunder' railguns. A single tungsten alloy kinetic energy projectile can penetrate several kilometers of rock and even break through the airships of the North City. In addition, the base's outer walls are made of three layers of composite armor, with a defensive wall thickness of 12 meters. Conventional kinetic energy weapons will only leave a shallow mark when they hit it..."

The people from the Qian Yuan Upper City military headquarters introduced Zhang Ce, Chen Feng, and others behind them, leading them through a transparent corridor spanning the mountain range and towards the military headquarters conference room in the center of the mountain range.

Chen Feng looked out the arched window at the mountain range that had been completely transformed by the Great Xia military, and for a moment he stopped in his tracks.

Higher in the sky, several silver streaks of light silently flew by.

Looking further into the sky, one can see tiny black dots suspended in near-Earth orbit. These are the thirty-six "Mysterious Thunder" orbital cannon platforms, reflecting a cold metallic luster under the starlight, like a string of steel stars.

Beneath Chen Feng's feet lies a canyon thousands of meters deep, with layers of geomagnetic defense networks and concealed fortifications at the bottom. Countless engineering robotic arms are loading and unloading supplies at the cave entrances in the mountain walls, continuously sending military equipment and materials deep into the mountain's interior.

The entire mountain range wasn't "added" with defenses; rather, from the surface to underground, it was completely transformed by the military into a seamless, never-ending war machine.

It's like a giant steel beast buried deep in the mountain, yet gazing up at the sky.

They lie dormant in peacetime, but once war breaks out, they will bare all their fangs and crush any invading enemies outside their defensive perimeter.

"Beicheng has aircraft carriers, so what about our aircraft carriers?" Li Yuanwei asked.

The Qian Yuan officer leading the way turned around and gave a wicked smile.

"We currently only have the 'Sky' in service, but two more aircraft carriers will be delivered to us soon... You should be proud of that; Gu Yongshangcheng handled at least 70% of the design and assembly of these behemoths."

"Sounds good, but the cruise missiles in Beicheng are no joke." Li Yuanwei smiled.

The Qian Yuan officer smiled.

They entered the access code into the mechanical door of yet another passage.

"That is indeed a bit troublesome, but the batch of guys you've transported will soon change the entire landscape of the war."

"How so?" Chen Feng asked.

......

"The truly terrifying aspect of the 'Jin' isn't their individual combat abilities, but rather their evolutionary adaptability."

In the conference room of the military headquarters, more than twenty officers of the Great Xia Army were listening intently to the conclusions of the scientists from the Military Research Institute.

Even though this meeting was specifically set up for Gu Yong's Shangcheng transport team, all the Qian Yuan officers present were of extremely high rank, and even Zhang Ce could only sit at the back of the conference table.

Meanwhile, Chen Feng and other Heavenly Realm experts could only lean against the wall of the conference room, listening to the important figures in front of them discuss the military cooperation that was about to take place between the two upper cities.

"As you all know, whether it's combat mechs or railguns, the parameters of all standard weapons are fixed. But once they encounter new types of armies or special powerful individuals, their combat effectiveness will be reduced by more than half."

With a flick of their finger, the researchers at the Military Research Institute started playing "Jin's" combat video.

[Earlier Experiment Log: When "Jin" was forcibly submerged in a deep area with extremely high water pressure, its body began to struggle wildly until it finally lost all life. However, after a period of time, its twisted body began to slowly recover...]

[Earlier Experiment Log: As a hail of bullets rained down, layers of keratinous shields gradually rose from "Jin's" body surface. The defensive capabilities of its wounded body increased exponentially, and soon a suit of hard armor grew...]

[Earlier Experiment Log: When the high-energy laser beam swept across, "Jin" was burned in half at the waist. However, after their bodies fell to the ground, dark purple energy-absorbing patterns quickly appeared on their bodies, and faint white smoke began to rise from the laser-hit areas, indicating that they had begun to heal themselves...]

"This is what we call evolutionary adaptation."

The scientist explained with a smile.

"They are not like the war machines of North City, nor are they simply high-level combatants. They are the product of the combination of biological neurons and Tia's core. After each battle and each attack, their core units will undergo targeted evolution within 72 hours, specifically strengthening their defense, attack, and survival forms."

"So," a major general on the left spoke, his voice low, "that they'll grow stronger as long as they're not destroyed on the spot?"

"To be precise, it becomes more and more 'suitable' for the battlefield the more they fight," the scientist corrected.

"Moreover, with the help of the Xiang family of Gu Yongshang City, their adaptation speed is getting faster and faster. By this current batch of 'Embers,' their adaptation and evolution speed has basically met the needs of combat."

"Can you control it?"

Zhou Zhenchuan, the person in charge of the operation in Qianyuan Shangcheng, suddenly spoke up.

"With such strong evolutionary capabilities, if they get out of control, their threat is more terrifying than any Heavenly Rank expert."

"Each 'Jin' has been implanted with a dual command lock in its operational core." The scientist displayed a diagram of the core structure of these war machines on the screen.

"The first layer is a biological gene lock, which only recognizes the authorized frequency band of the Great Xia Military; the second layer is the self-destruct device of the energy core. Once it is out of control for more than 48 hours, or if the command system is tampered with, their energy core will collapse directly, and nothing will grow within a radius of 100 meters."

"Sounds good." Zhou Zhenchuan smiled.

"Yes, Major General."

Chen Feng, standing behind the conference table, remained silent throughout.

He simply stared intently at the black weapon in the holographic projection that was constantly evolving amidst destruction.

He escorted "Jin" all the way from Gu Yong Shang City, but he never imagined that it would be such a terrifying weapon of war.

He suddenly remembered Zong Chiyuan's Crimson Blood Royal Family power and the Illusion Demon Prince's mental illusions.

If "Jhin" can evolve, will it also be able to develop corresponding means of resistance against the Darkin's spatial abilities and the mental erosion of the Phantoms?

If so, then these self-replicating weapons mean they are uncontrollable.

Like a wild beast kept in captivity, it will one day turn on its master.

"If no one has any objections, we will deploy this batch of prototypes tonight. Let them play with our prisoners first."
