With the official launch of the Nascent Soul-class mecha development program, Qixing, Qingyu Heavy Industry, and Taicang Machinery Manufacturing entered a full-scale wartime state. R&D departments were ablaze with activity, with engineers, rune masters, psychic technicians, and various high-ranking cultivators working tirelessly through the night, striving to usher in a new era of immortal cultivation mecha technology.

At this moment, Ranxing's technology circle is experiencing a silent war.

[Qixing Company: Steady Progress, Breaking Through Bottlenecks] Lab 1: Psionic Engine Optimization Team

In a large laboratory on the fourth floor of Qixing Company, a group of rune engineers were surrounding a huge metal cube, carefully observing the energy readings on the instrument.

"The main rune array is stable, and the power output in preliminary tests has reached the peak Jindan level!" an engineer shouted excitedly.

However, the R&D director frowned, "Not enough. Our target is a Nascent Soul-class mecha. This power can only barely support a Golden Core-class mecha in full combat. A true Nascent Soul-class mecha requires a much higher spiritual energy supply."

"But if we continue to increase the psychic energy conduction rate, the rune array will be overloaded." A young engineer was worried.

Another veteran engineer coughed and squinted his eyes. "Have you considered optimizing the rune array's stacking?" Past mecha systems have always had a single-layer core, designed according to the energy transmission path from foundation-building to golden elixir. But if we use a dual-layer core, or even multiple layers of psychic circuits, can we further improve energy efficiency?"

Everyone was startled, and then began to calculate frantically on the rune board -

Single-layer circuit: psychic energy loss 14.2%, power 21 million units Double-layer circuit: psychic energy loss 9.3%, power 28 million units Triple-layer circuit: psychic energy loss 5.6%, power 36 million units

"It's done!" the engineers cheered.

The optimized design of the multi-layer rune circuit has finally taken the first step, and is only one step away from becoming a true Nascent Soul-level engine!

Laboratory 2: Mecha Skeleton Load-bearing Capacity Modification

At the same time, in another research institute of Qixing Company, a metal frame was fixed on the experimental table, and several senior material engineers and engineers surrounded it to test its pressure resistance.

"Increase the psychic impact and test the maximum carrying capacity."

Accompanied by a low humming sound, a huge amount of energy hit the main frame of the mecha, and the value on the pressure gauge continued to soar.

50 million units…60 million units…72 million units!

"Stop! Microcracks are starting to appear on the skeleton!" The materials engineer immediately called a halt.

"Sure enough, no matter how much ordinary alloys are strengthened, they cannot bear the spiritual power strength of the Nascent Soul Mecha." The head of the R&D department frowned.

A rune material expert pondered for a moment and suddenly said, "Perhaps we can try a new alloy combination—'Primordial Black Iron' + 'Starlight Refined Gold'!"

Everyone's eyes lit up.

"But these two materials are expensive and extremely difficult to process," a young engineer worried.

The R&D director decisively ordered: "We must come up with the best solution at all costs. Qixing Company cannot afford to lose this time!"

[Qingyu Heavy Industry: Striving for military technology and strengthening firepower]

Compared with Qixing Company's steady and cautious approach, Qingyu Heavy Industry's R&D team is more inclined to develop extreme firepower and defense.

In their core laboratory, a fully armed military representative stood in front of the screen, watching the mecha turret on the test bench that was constantly being adjusted.

"How is the progress on the Nascent Soul-level rune cannon we requested?" the military representative asked coldly.

The engineer wiped his sweat off his face and replied, "We have completed the first phase of testing. The current output power has reached the spiritual energy fluctuations of an ordinary Divine Transformation cultivator."

The military representative nodded and said, "Okay, let's conduct the live-fire test immediately."

"But... our defense system has not caught up yet, and the shield technology of the Nascent Soul-level mecha is not yet complete--" the engineer tried to explain.

"It doesn't matter. Our style at Qingyu Heavy Industry is that offense is the best defense." The military representative didn't care.

In the laboratory, a new type of rune cannon was mounted on the right arm of the mecha. With a roar, a blazing white rune beam shot out, instantly penetrating the ten-meter-thick defensive wall and even directly shattering the metal shield at the rear!

"The power exceeds the standard...but it's not a big problem." The engineers wiped their sweat.

[Taicang Machinery: Lightweight + Ultra-High Maneuverability]

Taicang Machinery's R&D style is completely different from the previous two companies. They always adhere to the concept of "speed first", so their Nascent Soul-level mecha research and development focus is on how to make the mecha have super high speed and flexibility without losing defensive capabilities.

In their laboratory, a lightweight mecha is testing its propulsion system.

"The new psychic propulsion system is a success! According to calculations, its maximum sprint speed is three times that of a Jindan-class mecha, and it can maintain high-speed operation for at least thirty seconds."

An engineer excitedly presents data.

However, the project manager frowned. "Thirty seconds? That's too short! On the battlefield, this booster would only last for a short burst, not a long battle!"

Another rune master pondered for a moment and said, "What if we add a self-circulating mechanism to the psychic circuit? This way, during the advancement, we can use additional absorption devices to replenish the consumed psychic energy from the surrounding battlefield pools."

"This plan is feasible!" The supervisor immediately approved it. "Test it immediately and optimize the propulsion system to allow the Nascent Soul mecha to maintain its overspeed state for at least two minutes!"

The R&D competition among the three major companies has entered a fierce stage!

In the following days, the R&D teams of the three companies raced against time to continuously optimize their solutions.

Qixing Company: Continuing to optimize the multi-layered psychic circuits, they finally broke through the core energy supply problem of the Nascent Soul class! Qingyu Heavy Industry: Developed the God Transformation Rune Cannon, but due to the lagging defense system, their mecha still has a huge flaw! Taicang Machinery: Breakthrough the speed of the Nascent Soul class mecha to five times that of the Golden Core class mecha, but the shield adaptation problem is still a headache!

The three companies have each made breakthroughs, but have also encountered bottlenecks, and the battle situation is still full of unknowns.

The old chairman's observation

In the top-floor office of Qixing Company, the old chairman stood in front of the window, looking at the night view of the city with deep eyes.

"Sure enough, they are also moving..." the old chairman murmured softly.

He knew that the competition for Nascent Soul-level mechas had officially begun.

The next step will be the trial production of the actual finished product.

And whoever can be the first to come up with a true Nascent Soul-level mecha will become the leader of the immortal mecha era!
