Nuwa, the goddess of immortality, said that cultivating immortality does not require spiritual energ

"It's done! It's finally done!"

As evening fell, inside the weapon-refining workshop, Chen Yun carefully held a metal sphere the size of a human head, its surface covered with intricate and precise spiritual patterns, his face beaming with barely suppressed excitement.

The sphere is an upgraded version of the Ghost Sphere.

At its core, a silver-white seed of law is firmly locked in the center, emitting a stable and gentle light. Strands of law power are flowing, storing, and releasing in an orderly manner through the intricate spiritual pattern structure inside.

To create this upgraded energy core, he and Qin Le spent the entire afternoon in the workshop. They failed twice before finally succeeding on their third attempt.

The reason for the failure really lay with Chen Yun himself.

The upgrade plan and theoretical design provided by Qin Le were fine, but in the actual refining process, it was necessary to engrave thousands of fine, hair-like spiritual runes on the surface and inner layer of the sphere with absolute precision.

This step requires extremely high precision in manipulating spiritual power, and only Chen Yun can do it himself, since Qin Le has no spiritual power.

Two failures made Chen Yun realize that he was still far from mastering the basics of a weapon refiner—theory can be imaginative, but practical skills require hard work and countless repetitions.

"Don't just get too excited," Qin Le said with a smile, "Let's go fill our stomachs first."

"Too."

Chen Yun nodded, carefully put the upgraded Ghost Craft Ball into his storage ring, and left the workshop with Qin Le, heading towards the canteen.

On the way, Chen Yun couldn't help but ask the question that had been bothering him all afternoon: "Qin Le, I've noticed that you seem to know more about the properties of those weapon-refining materials than I do!"

During the production process, Qin Le was very familiar with the details of the combination of various materials, the smelting temperature, the conduction of spiritual energy, etc. He could even point out some uncommon uses of materials unique to the celestial realm, which made even a professional weapon refiner like himself feel inferior.

The key is that Qin Le should have had no chance to access many of the materials.

Upon hearing this question, Qin Le smiled, took out a smooth jade slip from his pocket, and waved it:

"Last time I went to the Heavenly Realm, it was given to me by Laozi. It contains detailed records of the characteristics, origins, and mutual restraint relationships of various materials known in the Three Realms for alchemy and weapon crafting, as well as illustrations of many rare materials. I still haven't finished reading it."

"I see..." Chen Yun suddenly realized, then felt a little envious.

With the material encyclopedia personally compiled by Laozi, it would be difficult for Qin Le to transform into a human-shaped material dictionary.

"I'll let you take a look when I've finished reading them all," Qin Le said casually.

"Really?! You said it yourself! Don't go back on your word!" Chen Yun's eyes lit up, and he became excited instantly.

This jade slip might only broaden Qin Le's horizons, but for someone like him who studies weapon crafting, it is an invaluable treasure that he has always dreamed of!

He hadn't dared to ask before, partly because he felt the gift was too valuable, and partly because he was afraid that Laozi wouldn't allow it to be shared.

"Don't worry, I won't forget." Qin Le nodded and smiled.

When Laozi gave it to him, he did not specifically instruct him not to share it with others. Given Laozi's wisdom, he must have tacitly allowed him to share it with trustworthy people.

When the two arrived at the cafeteria, several other dining companions had already been waiting for a while.

After getting their food and sitting down, Chu Xiaonan eagerly leaned over, her eyes full of curiosity: "Qin Le, what's the underworld like? Tell us about it!"

These words immediately piqued everyone's interest, and they all looked at Qin Le—no one was not curious about that mysterious place that governed reincarnation.

"Actually, I didn't feel anything special." Qin Le picked up a piece of food and said honestly, "I went to two places after I finished my business, and I didn't have time to wander around at all."

"And what about the King of Hell? What does he look like? Is he like the legends, with a blue face and fangs, really scary?" Li Yanran pressed, as girls seemed particularly concerned about such terrifying images.

"You guessed wrong?" Qin Le smiled as he recalled the refined middle-aged Yama King: "The Yama King himself... is a rather handsome uncle, with a dignified and refined demeanor, not at all scary."

"Huh?! Yama is actually a handsome older man?!" Li Yanran exclaimed, her eyes wide with surprise.

The others were also surprised; this answer truly overturned their previous expectations.

"I was quite surprised at the time."

Qin Le nodded with a smile. When he first met them, he thought about the same things they did.

The days flowed by peacefully, and half a month had passed since Qin Le returned from the underworld.

Life in the mortal realm remained at a leisurely pace, with academies, cultivation, and small gatherings with friends; nothing earth-shattering happened.

Compared to the constant tension of battles in the celestial realm, this tranquility even seems somewhat luxurious.

But from another perspective, isn't the brutal fighting in the celestial realm, which happens day after day, just another form of monotony and repetition?

That noon, right after lunch, Chen Yun mysteriously dragged Qin Le to the academy's private training ground.

"What? Has 'Truth' been upgraded again?" Qin Le looked at the empty training ground and guessed.

Chen Yun brought him here most likely to test out a new truth.

"I didn't upgrade that." Chen Yun shook his head, but couldn't hide his smug smile. "First, help me raise the protection level of the training ground to the highest level, and I'll show you something... absolutely awesome!"

"Alright then." Qin Le didn't ask any more questions and raised his hand to press the empty space of the training ground.

In an instant, the space above and around the training ground distorted slightly, and thousands of invisible spacetime barriers were instantly superimposed and solidified, their defensive strength being enough to easily withstand the barrage of attacks from a regular Celestial level—this was the standard configuration for testing the power of the Truth Explosion in the past.

"Hehe, watch closely!"

Chen Yun rubbed his hands excitedly, then solemnly took out his new toy from his storage ring.

Om-!

Ripples spread through the space, and a colossal object suddenly appeared in the center of the training field.

That was a giant humanoid mech that was nearly 100 meters tall!

The streamlined and cool body, with a striking black and red color scheme as the main theme, and the joints reveal the beauty of precision mechanics. The overall shape is full of power and futuristic technology. Standing there quietly, it brings an invisible pressure.

Even Qin Le's heart skipped a beat when he saw it for the first time—this thing is really cool!

"Let me show you!"

Chen Yun eagerly leaped into the air and landed precisely in the cockpit on the mech's chest. The hatch closed silently.

The next second, the giant mecha's eyes suddenly lit up with a bright blue light.

Immediately afterwards, a semi-transparent energy shield, flowing with silvery-white light, rapidly covered every inch of the mech's outer armor like mercury spilling onto the ground.

"A Law Shield?" Qin Le recognized the essence of the shield at a glance and raised an eyebrow slightly.

The giant mecha slowly lifted off the ground with a deep hum, its movements fluid and natural.

Then, it raised its two huge mechanical arms, flipped the arms over to reveal two menacing cannon barrels.

Om-!

The light from the cannon's muzzle condensed, and in the next instant, beams of silver-white light, compressed and condensed from the pure power of laws, shot out like a storm!

The light projectiles formed an almost continuous, bright band of light in the air, bombarding the outermost spacetime barrier set up by Qin Le!

Boom boom boom boom—!

A series of explosions rang out, and silvery-white auras of law burst open on the surface of the barrier. Although they failed to penetrate the defense that was stacked with thousands of layers, the intensity of the continuous law-level attacks was already astonishing.

"Wow..." Qin Le couldn't help but murmur in admiration as he watched this scene.

Piloting this mecha, Chen Yun already possesses the capability to confront a Celestial Immortal head-on—at least in terms of attack and defense hardware.

The Law Shield can withstand Law attacks, and the Law Cannon can break through the defenses of a Celestial Immortal. As for mobility... Chen Yun couldn't possibly ignore this most crucial factor.

This means that Chen Yun, relying on his theory of technological cultivation and the top-tier energy provided by Qin Le, has created a groundbreaking artifact that allows cultivators at the Refinement of Void and Integration of Dao to challenge Earth Immortals!

Against a Chaos Beast at the Earth Immortal level, victory is almost guaranteed.

After a thoroughly enjoyable demonstration, the mecha landed smoothly, the hatch opened, and Chen Yun jumped out excitedly, flying to Qin Le with sparkling eyes and asking:

"How is it? Handsome, right?"
