The contents were brief

The space was filled with countless shelves, cabinets, and boxes.

To the left—the entire wall was covered with shelves filled with jade bottles of all sizes, each containing a pill. Su Zhan casually picked one up and smelled it; the Myriad Poisons Divine Farmer's Canon echoed in his Sea of Consciousness.

[The Myriad Poisons Divine Farmer's Canon]: Seventh-Rank Heavenly Net Pill! A top-tier elixir capable of repairing damage to the soul! This entire shelf is filled with Grade 7 and above!

On the right-hand side, dozens of weapons emitting various colors of light are neatly arranged on Weapons rack. The lowest grade is Martial King Rank. The innermost one is a jet-black longsword that floats in mid-air, the patterns on the blade moving as if they were alive.

[The Immovable Wisdom King Wall]: The material of that sword—it's the same metal used in the Main Altar building, but its purity is at least five times higher. Give it to me! Give it to me! Give it to me!

Directly ahead—a row of Crystal cabinets contained various heavenly materials and earthly treasures. Among them were several Spirit Grass that Su Zhan did not recognize, and the Ancient Life Tree sent out a soft but urgent call from within his Sea of Consciousness.

[Ancient Life Tree]: That... that purple flower... is the Nine-Turn Reincarnation Lotus! A top-grade Spirit Plant that can replenish the energy of Spatial Principle... Sealing Formation... Sealing Formation can be used...

Su Zhan stopped moving.

Are you sure?

[Ancient Life Tree]: Confirmed! The Nine-Turn Reincarnation Lotus contains extremely pure Spatial Principle essence. After being absorbed by the core sphere of the Mustard Seed Grotto-Heaven, it can be transformed into Sealing Formation energy. One Reincarnation Lotus can replenish approximately... two to three percent of the total Sealing Formation energy.

Su Zhan glanced at the cabinet.

There are three purple lotus plants.

Three plants, six to nine percent. Adding the original 17 percent—at most, the Sealing Formation energy can be pushed to 26 percent.

The duration of the ordeal was extended from six months to approximately ten months.

It's not enough, but it's better than nothing.

"Move everything."

Su Zhan took off the half of his still- intact outer garment and laid it flat on the ground to use as a bag.

The Cultivation Method were already arguing fiercely in their Sea of Consciousness, fighting for the right to eat first.

Su Zhan completely ignored them, his hands constantly stuffing things into his pockets.

Elixir – all are necessary.

Weapons – pick the best quality ones.

heavenly materials and earthly treasures —not a single one remained.

In the corner was a small locked box. The lock was a Blood Curse Lock, which could only be opened with the Sect Master's blood. Su Zhan was too lazy to bother, so he used the three thousand threads of the Thousand-Thread Lock to drill into the keyhole and completely dismantle the internal structure.

The box was opened. Inside was only a yellowed Beast-Skin Scroll.

Su Zhan unfolded it and took a look.

What's written above isn't Cultivation Method, but a handwritten note— the Sect Master's own handwriting.

The content is very short.

"I have cultivated for seventeen hundred years, traversing the Demon Sea and visiting countless ancient ruins, finally finding the entrance to the Mustard Seed Grotto-Heaven in the one hundred and thirty-second year. Sealing Formation within the cave heaven is an object called the 'Primordial Demon Embryo.' This object is formless and intangible, feeding on the fear of all living beings. I once attempted to probe the Sealing Formation, merely touching the outer layer with my divine sense—only to awaken from a nightmare three days later. Since then, I have dared not explore it again."

"Primordial Demon Embryo." Su Zhan chewed on these four words.

[Thunder Emperor Divine Seat]: (in a heavy tone) The Primordial Demon Embryo... I have a recollection of it. A forbidden object from High Antiquity times. The specific details are now blurred, but one thing I remember very clearly—it cannot be killed.

Su Zhan stuffed the Beast-Skin Scroll into his robes.

What to do with something that can't be killed?

[Thunder Emperor Divine Seat]: Permanently locked.

There were still many things left in the Treasury, but Su Zhan's "pocket" had limited capacity. He packed away all the most valuable and practical items, and the rest— the Immovable Wisdom King Wall— was ready to be eaten.

Su Zhan tossed several unwanted weapons to the Immovable Wisdom King Wall.

A dark golden light surged within his body, Immovable Wisdom King Wall crunched crisply as he chewed on it.

[Immovable Wisdom King Wall]: It tastes much better than the fragments above. The concentration of Principle in this batch of metals is even higher.

After packing up, Su Zhan carried his pile of spoils, flew up from the entrance of the Treasury, and returned to the seabed through the ruins passage with four layers of Restriction.

The purple light shield of the Myriad Poisons Divine Farmer's Canon protected him completely.

It swam three hundred feet upstream and broke out of the sea.

The sky was still leaden gray. The sea was still dark red.
