Looking at the rising sun outside, a smile appeared on the corner of Lu Yao's mouth, this night's harvest was really too great, far exceeding his previous income from adventures in the Ninety Percent Nine Secret Realm in the Cultivation Realm.

The only exception was Lu Yao's acquisition of the Xuanyuan Water Control Flag and the "Kun Demon Map", but this time he obtained the immortal body, but he had not yet studied what it was for, and there was also a small part of the Xuanyuan Water Control Flag remnant flag, which would not be of much help to Lu Yao at the moment, but not necessarily in the future.

Lu Yao got used to the dazzling sunlight a little, and since he had missed the purple qi at the moment when the sun first rose, he simply stopped cultivating the secret method of the sun's true fire today.

He looked around at the valley and found that it was very similar to the suggested map that Doctor Yang had drawn for himself, Lu Yao was stunned for a moment, and then realized in his heart.

The stone chamber that came out of itself must be the cave house secretly built by the East China Sea School, and the valley it leads to is naturally the territory of the East China Sea School.

In order to confirm what he thought, Lu Yao's divine consciousness emanated, covering an area of one hundred and eighty meters, and sure enough, under the cover of his divine sense, he saw dilapidated ancient buildings in the valley.

Due to disrepair, many places have been turned into ruins, and green creepers have crawled all over the building, turning it into a kingdom of greenery.

Lu Yao wandered in this green ocean, quietly feeling that this aura was much richer than the outside, and it was not even inferior to the concentration of aura absorbed by his water spirit body on the sea.

He knew that it was because there were many herbs growing scattered throughout this valley, as well as a very small number of low-grade elixirs and spiritual plants.

In the backyard of a large hall, Lu Yao found a low-level spirit plant cloud mist tea tree with a history of six hundred years, and there were more than a dozen secondary spirit plant cloud mist tea trees sparsely growing near the spirit tea tree.

If it weren't for Lu Yao's surprise, these dozen or so secondary spirit plant cloud mist tea trees should have been propagated by the cloud mist spirit tea mother plant itself.

At that moment, Lu Yao was not polite at all, took out a hoe that he had purchased when he planted the elixir from Fanghu Immortal Island, and with a sharp swing, he dug out the Yunwu Spirit Tea Mother Plant and the dozen or so Yunwu Tea Trees in this valley and transplanted them into the woods in Fanghu Immortal Island.

The spiritual mist inside Fanghu Immortal Island is much more abundant than the spiritual energy in the mist in the valley of the East China Sea Courtyard, which is very suitable for the growth and evolution of cloud mist spiritual tea.

As for some other ordinary cloud tea trees, Lu Yao didn't dig them again and let them grow freely here.

Along the way, he saw many herbs, and as long as they reached a certain growth year, he transplanted them all into Fanghu Immortal Island.

As for the low-grade elixir, he didn't let go of any of them. Many of the low-grade elixirs growing in the valley were related to the spiritual grass seeds that Lu Yao had obtained from Physician Yang last time, and they were suitable for refining the medicinal materials of Peiyuan Dan, Cleansing Pill and Poison Pill.

Lu Yao dug up a total of two grass fruits that were more than 100 years old, five ghost cut grasses, five horse horse lotus plants, and three dragon beard grass and ginseng fruits.

The number of plants that are less than 100 years old is a bit much, more than 20 plants. Less than ten years because the medicinal effect is too weak, it is not suitable for alchemy.

The most important thing is that the earth has entered the end of the Dharma era, and many low-level elixirs that originally grew quickly in the cultivation realm have slowed down their growth efficiency a lot due to the lack of spiritual energy.

However, it stands to reason that no one has disturbed the valley of the East China Sea Courtyard for more than six hundred years, and there should be more than a little Centennial Grass growing, right? Even if the elixir is not managed, the speed of self-reproduction will not be too slow.

However, judging from the current situation, these hundred-year-old low-grade elixirs were only discovered by themselves in some hidden places with their divine sense, and most of the elixirs that grew normally outside were less than ten or twenty years old.

This shows that there must be someone who often comes here to pick elixir, maybe it is someone who is tempted by Haiyazi like the six-fingered empty child.

It's no wonder why Dr. Yang and his female classmate came to this valley last time to explore, and the harvest was so small? How could there be any good things left in the valley that someone came to harvest almost every once in a while? It was all garbage that others couldn't look at.

After scraping these medicinal materials, Lu Yao estimated that he could open the furnace and refine the pills more than a dozen times, and then he could gradually cultivate the people around him.

This time, he did a relatively good job, using his divine sense like plowing the ground, carefully harvesting and scraping all the low-grade elixirs in the valley several times, not even leaving the elixir seeds, and transplanting them all to the simple medicine garden that he had opened up in the woods of Fanghu Immortal Island.

After confirming that he had not missed anything, Lu Yao walked towards his final destination, the spirit stone embedded in the wall of the stone chamber in a cave.

This was the original purpose of Lu Yao's visit to this valley, who knew that the final harvest of this trip was far beyond his imagination, and the spirit stone had become the most insignificant item.

But in order to help his wife check the true cause of why she couldn't cultivate, he still had to bring this spirit stone back.

The entrance to the cave is hidden by weeds and vines, and if it weren't for the map given by Dr. Yang, it would have been difficult for ordinary people to find this place. Especially before Dr. Yang and the others left, they deliberately covered the entrance of the cave with vines.

After decades of continuous self-reproduction and growth, the nearby stone wall has long been climbed to the full, leaving no gaps.

Lu Yao concentrated his spiritual power with both hands, grabbed the branches of those vines, struggled to pull out the corridor where only one person was left to pass, and walked into the cave, which was empty, except for a spirit stone on the wall that was more than one person high, there was nothing left, and it had already been picked up by the people in front.

Lu Yao estimated that if it weren't for the spirit stone being embedded in the stone wall, and the prohibition protection was arranged, it is estimated that they would have chiseled this stone wall to get rid of the spirit stone.

He came to the spirit stone, stretched out his finger and tapped on the surface, and a soft circle of light flipped out, bounceing Lu Yao away.

"Sure enough, it's a protective ban, but it's not very difficult for me, as long as I find the key nodes, it's very simple to break this protective ban. ”

Lu Yao pondered, released his divine sense, and began to carefully study the prohibitions arranged inside and outside the spirit measuring stone.

After about an hour, he walked back to the spirit stone, this time he did not plan to break the ban from the front, but regarded himself as a person who detected the spirit root, and gently placed his palm on the spirit stone, concentrating his spiritual power to sense the spirit stone.

Suddenly, a deep blue light erupted from the surface of the spirit measuring stone, reflecting the entire cave into a world of blue light, as if everything in the entire heaven and earth had lost its color, and there was only one kind of light left.

"Sure enough, it's worthy of the water system Heavenly Spirit Root, this posture is really dick-like!"

Lu Yao muttered to himself, but his hand was not withdrawn, and the spiritual power continued to spread along the palm of his hand towards the connection between the spirit measuring stone and the nearby stone wall, shattering the connection points between them one by one.
