Chapter 627: 延寿奇珍

“I’m going back now.”

Meng Chuan, who had been standing before the lake, split off a stream of light and left Kunyun Secret Realm, rushing towards the Goddess River Domain. Only a primordial spirit avatar remained in Kunyun Secret Realm.

“This realm mansion is indeed a treasure trove for cultivation.” Meng Chuan’s primordial spirit avatar stayed, firstly to control Kunyun Secret Realm, and secondly because it offered the best cultivation environment. Neither Cangyuan Realm nor Qianshan Star could compare to the realm mansion.

Beyond being the core for controlling Kunyun Secret Realm, the realm mansion also served as a cultivation cave dwelling. It wasn't just its ability to quickly nurture the physical body and primordial spirit that made it valuable; there were other advantages.

“The realm mansion also has two special quiet rooms. The cultivation flow rate in one room is identical to the outside world, while in another, it’s only one-tenth of the outside world’s.” Meng Chuan was very surprised. The normal time flow rate in the entire Kunyun Secret Realm was ten times that of the outside world, yet that Eighth Tribulation realm mighty one had separately built two special quiet rooms with different time flow rates.

“Cultivating in different quiet rooms allows for separate comprehension of changes in time flow.” Meng Chuan highly valued this. The higher one's cultivation realm, the more effort one had to put into the aspect of time. This was because pure spatial rules were merely the strongest among Sixth Tribulation realm rules. To become a Seventh Tribulation realm or even Eighth Tribulation realm expert, one had to achieve extremely high mastery in the time lineage.

Although he felt pressure from the impending heavenly tribulation, having reached his current realm after only 2,600 years of cultivation, Meng Chuan naturally had ambitions for his future cultivation. He wanted to become a Seventh Tribulation realm expert, and even considered... could he become an Eighth Tribulation realm expert? And allow his home, Cangyuan Realm, to also become a high-level life world, forever shining and strong?

If the hope of becoming a Seventh Tribulation realm expert was slim, then the hope of becoming an Eighth Tribulation realm expert was almost negligible, as it was normal for an entire era in the River of Spacetime to not produce a single Eighth Tribulation realm expert. Yet, one must still strive.

Whoosh. Meng Chuan's true body from beyond the domain traveled through the River of Spacetime, spending nearly half a month to rush back to Cangyuan Realm in the Goddess River Domain. After mastering the rules of thunder, Meng Chuan's travel speed was several times faster than before. In terms of travel, he was considered top-tier among Sixth Tribulation realm mighty ones. Of course, those who had mastered complete spatial rules were undoubtedly the fastest travelers among Sixth Tribulation realm mighty ones, far surpassing Meng Chuan's current speed.

“I’m back.” Meng Chuan's true body from beyond the domain passed through Cangyuan Realm's membrane wall, looking at the beautiful mountains and rivers, and a smile involuntarily appeared at the familiar scenery of his hometown. Meng Chuan took a step and returned to Yuanchu Mountain.

“A trip to Kunyun Secret Realm yielded about 560,000 square units of treasures.” Meng Chuan was in an excellent mood. “This will make things much easier.” Before undergoing the tribulation, he had to prepare for his family and for his entire home, Cangyuan Realm.

Patriarch Cangyuan had left many treasures for the sect to use, but over a million years, his descendants had almost completely used them up. As for even more valuable treasures, there were significant restrictions on withdrawing them. As a Sixth Tribulation realm expert who had not yet undergone the tribulation, Meng Chuan had received numerous gifts from the Patriarch. Naturally, many of these had to be left for his homeland and the sect. However, he also had to consider his own cultivation and extending the lifespans of his parents, wife, and others. Previously, he had been very tight on resources, but now things were much more relaxed.

“Many of these rare treasures can be directly kept on Yuanchu Mountain this time.”

“Some items suitable for Tribulation realm experts can be exchanged at the Eternal Tower for 100,000 square units of ‘basic treasures’ and kept on Yuanchu Mountain.” Meng Chuan nodded. “This would allow Cangyuan Realm to prosper comfortably for at least another million years.” If... if he failed his tribulation, he hoped that in the next million years, Cangyuan Realm might produce another Sixth Tribulation realm expert to expand Cangyuan Realm. It took a long time for a sapling to grow into a large tree, and the growth and expansion of a life world were even slower.

Inside the Heaven and Earth Hall's treasure vault:

“Meng Chuan.” The white-robed elder greeted him with a smile. “Have you brought back the Heavenly Punishment Diagram?”

“I’ve brought it back,” Meng Chuan nodded. Taking the Heavenly Punishment Diagram to Kunyun Secret Realm required an exchange, an equivalent of up to 650,000 square units of outer realm primordial crystals. This was still the price set by Patriarch Cangyuan for his descendants. Its actual value could be more than double, because such treasures were mostly in the hands of Seventh Tribulation realm mighty ones, or collected by high-level worlds. Pure outer realm primordial crystals simply couldn't attract them; they were practically unpurchasable.

“The deducted 650,000 square units can be returned to you,” the white-robed elder said with a slight smile.

“I wish to exchange for a longevity treasure,” Meng Chuan said.

“You know all nineteen longevity treasures collected by the old master.” The white-robed elder nodded. “Which one do you choose?”

Meng Chuan became serious. The nineteen longevity treasures ranged in price from 27,000 to 500,000 square units, with the more expensive ones being rarer.

“I want one drop of ‘Fire Source Liquid’,” Meng Chuan said without hesitation.

“You’re truly willing to spend that much,” the white-robed elder chuckled.

“It’s worth it,” Meng Chuan nodded. Fire Source Liquid, according to Patriarch Cangyuan's brief record, was a rare treasure from another universe, with one drop costing 200,000 square units.

The essence of extending lifespan was to perfect the life form. The more perfect and powerful a life form, the longer its lifespan naturally became. The most perfect life forms at the Venerable level were pure-blooded dragons, pure-blooded phoenixes, or Venerables whose foundations were built on ultimate arts, all with a lifespan of 5,000 years. Meng Chuan himself was like this back then. If one used rare treasures to perfect a life form to rival that of a young pure-blooded dragon, it would naturally have a 5,000-year lifespan. But to reach the absolute limit? Almost impossible!

“This drop of Fire Source Liquid is most suitable for Qiyue,” Meng Chuan knew clearly in his heart. “Qiyue has phoenix bloodline; Fire Source Liquid will have the best effect on her, estimated to extend her lifespan to three or four thousand years.” Liu Qiyue, although possessing phoenix bloodline, still had a gap to close to become a 'pure-blooded phoenix'. But with the help of Fire Source Liquid, she would be very close to a pure bloodline, lacking only a tiny bit.

“At that time, Qiyue's life will become more perfect, her life level will greatly improve, approaching that of a pure-blooded phoenix. Her cultivation will also become smoother,” Meng Chuan greatly anticipated.

At the Eternal Tower, Ninth Floor, on Qianshan Star:

“I still need to prepare one for my master,” Meng Chuan scanned the longevity items sold by the Eternal Tower. His master, Qin Wu, was just an ordinary Venerable, without any special bloodline. Extending his lifespan would be much easier than for Liu Qiyue.

In fact, because he had created a 'Heaven and Earth Realm ultimate art,' with the help of treasures, his master could directly transform into an 'Emperor-level special life form.' Transforming into an Emperor-level special life form had a higher threshold; one had to comprehend a Heaven and Earth Realm ultimate art and possess suitable treasures. Moreover, 'transforming into a special life form' was, after all, becoming another life form, with the possibility of failure and death. Even if successful, he would be limited to the Emperor level, with no hope of reaching the Tribulation realm. Despite these factors, his master Qin Wu still considered transforming into an Emperor-level life form to be a good option, never daring to hope for lifespan extension. With lifespan extension, he could hope to become an Emperor as a human, with a very safe breakthrough, and also a chance to challenge the Tribulation realm.

“The most suitable item for Master is this ‘World Tree Fruit’,” Meng Chuan slightly shook his head. “Back then, I received Senior Fei Yu's inheritance and formed a karmic bond. If I become an Eighth Tribulation realm expert, I would need to resolve this karma, either by protecting Fei Yu Realm for 100,000 years or by giving a 'World Tree' to Fei Yu Realm. Only now do I realize the value of a World Tree.” The World Tree was a legendary item. Even a single branch or a fruit from it was extremely valuable. For example, the World Tree Fruit Meng Chuan intended to buy for his master, Qin Wu, cost 80,000 square units.

A complete World Tree could produce thirty-six fruits in each cycle. And fruits were only part of the World Tree's value. One could imagine the preciousness of a 'complete World Tree.'

“An Eighth Tribulation realm expert protecting Fei Yu Realm for 100,000 years is equivalent to a World Tree?” Meng Chuan also somewhat understood the immense value of an Eighth Tribulation realm mighty one's time.

“I need this World Tree Fruit,” Meng Chuan stated.

“It requires 80,000 square units,” a grand voice echoed from above.
