"Are we the first to arrive?" Zhang Mingyang brought the disciples of Ji Shang Sect to the vicinity of the top-grade spirit stone mine. Except for the corpses on the ground, they did not see anyone else.

Several disciples immediately showed their delight, "Senior Brother Zhang, what are we waiting for? Let's start digging now before they arrive. And there might be spiritual essence in the spiritual stone mine, which can help Senior Brother Chai break through to the Great Perfection of the Golden Core."

"Yes, if Senior Brother Chai can break through, he might be the only one in the Nascent Soul stage in the secret realm. Then Gao Han and Kairos will be no match for him."

"It's a pity that we don't know where Senior Brother Chai is. I hope he can come here as soon as possible."

After a few people finished talking, they found the place where they first discovered the top-grade spirit stone mine and started mining.

Due to the different directions, they did not realize that two groups of people had been digging in the opposite direction for some time until they started digging.

Pan Jun and Junior Brother Zhang from Qixing Valley arrived shortly afterwards, but Liang Muheng was not there. They had lost him when they were escaping. The two searched for him for a long time but couldn't find him, so they had to give up temporarily and come here first.

The top-grade spirit stone mine is important, but the spiritual essence in the center of the spirit stone mine is more important.

When they found out that people from the Ji Shang Sect were already digging, they didn't run over to join in the fun. Instead, they found a place and started mining frantically.

In the cave opposite them, Gao Han and Zhongli Tingzhou had unknowingly dug a hundred meters deep.

The top-grade spirit stones were scattered at the beginning, but became increasingly dense later on, which meant that they were not far from the center of the spirit stone mine.

"It is indeed a top-grade spirit stone mine. The spiritual energy is rich and not much worse than a spirit cave." Gao Han put the hundreds of top-grade spirit stones he dug out into the Yayoi Ring.

"But there is still no spiritual cave." Zhongli Tingzhou said as he dug.

Later on, it was no longer soil, but various kinds of minerals with varying hardness. If you kept using a shovel, it might take a long time to dig out a spiritual stone.

Gao Han picked up a piece of top-grade spirit stone and threw it into his arms. The sleeping Fugui unconsciously held the top-grade spirit stone and began to absorb it slowly.

Compared to the absorption speed in the spirit cave at the beginning, the speed has now slowed down.

A piece of top-grade spirit stone is enough for it to absorb for a long time. It is estimated that when it stops absorbing spiritual energy, it will be the time to wake up.

Gao Han turned around and suddenly stepped on something with a stumbling sound. It turned out to be pieces of transparent crystal shells.

These crystal shells are all top-grade spirit stones that have absorbed all the spiritual energy. The only one who can do this is Zhongli Tingzhou.

Gao Han also put these crystal shells into the Yayoi Ring and warned: "Don't absorb these spirit stones at will. If you take too many, the number won't match."

"We did it ourselves, do we still need someone to supervise us?" Although Zhongli Tingzhou disagreed, he still obediently did not absorb these top-grade spirit stones.

“It’s just a precaution.” Gao Han said that for a heaven-defying treasure like the Yin-Yang Bead, the fewer people who know about it, the better.

Zhongli Tingzhou poked the sword in his hand against the wall, making a clanging sound.

It failed to cut through the metal and instead bounced back slightly.

Gao Han pinched off a small piece of metal with his hand. It was very dense. Although this metal could not store spiritual energy, some spiritual energy still seeped out of it, which meant that the spiritual energy here was so rich that even the metal ore was involuntarily contaminated by it.

"It seems that we have dug to the center of this top-grade spirit stone mine."

Gao Han collected these metals. This extremely dense metal is also a material for refining weapons.

After scraping away these metals, large areas of top-grade spirit stones were revealed, the density of which was several times higher than other places.

The two dug out these top-grade spirit stones, revealing a fist-sized spirit stone, which was no different from ordinary top-grade spirit stones. If one did not look closely, one would even mistake it for a top-grade spirit stone and put it away casually, if Gao Han had not sensed a different energy in this spirit stone.

“Is this the spiritual essence?”

When Gao Han saw this thing, his expression changed slightly.

Spiritual marrow is a liquefied treasure that looks a bit like spiritual fluid, but is very different.

Gao Han immediately dug it out. It was a piece only the size of a fist. It looked no different from an ordinary top-grade spirit stone. If you didn't look closely, you wouldn't even be able to detect its existence.

Zhongli Tingzhou's expression suddenly changed.

"What's wrong?" Gao Han noticed.

Zhongli Tingzhou turned his palm over, and the black energy was beating eagerly in his palm, "It wants it very much."

Gao Han's expression slightly changed. "It's all black. What's the use of this thing?"

"It may be related to the Yin-Yang Bead. The essence of the top-grade spirit stone ore is a great tonic." Zhongli Tingzhou said disapprovingly.

Gao Han handed him the spiritual essence and said, "Then absorb it. Even if others want to snatch it, they can't."

"Not leaving time for Yuanran to break through?" Zhongli Tingzhou said with a smile.

The energy of spiritual marrow is enormous. If a cultivator is facing a breakthrough, taking it can increase the chance of success. The higher the quality, the greater the chance of breakthrough.

The reason why other forces are so eager to get this top-grade spirit stone mine has a lot to do with the spirit marrow.

"He has accumulated enough energy during the period of Golden Core Great Perfection. It is only a matter of time before he breaks through. It is a waste to use spiritual marrow to break through. I believe that he will not use it even if you give it to him." Although Yuan Ran did not say it, Gao Han saw it at a glance.

Zhongli Tingzhou took the spiritual marrow in his hand, and the black air in his palm immediately drilled into it impatiently. The spiritual marrow was rapidly decreasing at a speed visible to the naked eye. The spiritual marrow that was swallowed by the black air was then fed back to the white side of the Yin-Yang Pearl.

The black and white sides briefly reached a balance, and several cracks on the surface of the Yin-Yang Bead were repaired at a speed visible to the naked eye.

"How is it?" Gao Han asked.

"Several cracks have been repaired." Zhongli Tingzhou said.

Gao Han's expression changed slightly. "Just one ball of spiritual essence can repair several cracks?"

Zhongli Tingzhou nodded.

Gao Han couldn't understand why the spirit essence was more effective than the spirit cave.

Zhongli Tingzhou said, "I..."

"I understand. The spiritual marrow is the essence condensed from an entire spiritual vein. And because this is a top-grade spiritual stone mine, if it is replaced with a high-grade or other grade spiritual stone mine, the effect may not be so obvious." Gao Han answered himself.

Zhongli Tingzhou was dissatisfied when he heard this: "Aren't you asking me?"

Gao Han glanced at him and asked, "Where does your sense of superiority come from?"

The despised Zhongli Tingzhou said confidently: "Your fiancé's sense of superiority."

Gao Han picked up a few stones on the ground with the tip of his sword and flew towards him.

"Uncle-master, have you dug up the spiritual marrow?" Yuan Ran came in and asked.

"I dug it up and used it up." Gao Han replied.

Yuan Ran choked for a moment, and it took him a long time to find his voice, "... so soon?"

Gao Han hummed and didn't explain further.

“…It’s fine to use it, but other sects may not believe it.” Yuan Ran said with a sigh.

"I know. Don't worry about it. If they have the ability, just come and rob us." Gao Han said indifferently.

After the previous battle with Kairos, those people would never dare to look for them, especially the demons. It would probably be too late for them to run away.

Yuan Ran remembered that he had come in for another reason, and they almost diverted his thoughts. "Oh, right, Ji Shang Zong and Qi Xing Gu are here too. I noticed that Chai Chengyun and Liang Muheng are not here."

Yuan Ran thought they would not be interested in the two of them, but he did not expect that as soon as he finished speaking, the two of them suddenly looked at him.

"You said Chai Chengyun and Liang Muheng didn't come to mine?"

Two pairs of eyes were staring at him. Yuan Ran almost thought there was something on his face. He nodded and said, "They really didn't come. I suspect they may have gone to find a place to break through."

Yuan Ran showed a trace of worry on his face.

Both of them are in the Great Perfection of Golden Core. In addition to looking for resources, there is another reason for entering the Shuangdong Secret Realm. They are on the verge of a breakthrough. If they can break through in the secret realm, the threat posed by two Yuanying stages will be greater than that of the Great Perfection of Golden Core.

Chai Chengyun wants the Eight Divine Swords, and Liang Muheng wants the Spirit Cave, so it is very likely that the two will join forces to deal with them.

"They won't join forces." Zhongli Tingzhou said.

Even Gao Han looked at him, "Why are you so sure?"

Yuan Ran looked curious.

Zhongli Tingzhou said lazily: "Because there is something wrong with Liang Muheng."

Gao Han: "Speak human language."

Yuan Ran: “…”

Zhongli Tingzhou: "He should have been possessed by Monroe and is probably assimilated now."

Yuan Ran's face changed drastically, and he asked hurriedly: "Uncle Master, are you serious? Liang Muheng was really assimilated by Monroe? But isn't he a genius? Even if Monroe is a genius, it is very difficult to assimilate a genius, and the possibility of failure is higher."

Gao Han suddenly asked, "What if Liang Muheng is seriously injured?"

Yuan Ran's face changed. He remembered that Senior Brother Chen had told him that Liang Muheng had used his blood essence to feed a small golden sword in order to kill Monroe. "If that's true, then it's possible. But how did Senior Uncle Zhongli know that?"

Zhongli Tingzhou said with a smile: "This is just my guess, it may not be true. It is possible that Monroe's soul was shattered by the golden sword."

Gao Han said: "I remember that after Liang Muheng was seriously injured by Kairos, he never took action again."

Yuan Ran said seriously: "Before it is confirmed, everything is possible. If Liang Muheng is really assimilated by Monroe, this matter must be reported. We can't just sit back and watch."

Zhongli Tingzhou smiled and said, "If he disappeared with Chai Chengyun, maybe Chai Chengyun was also assimilated by the demon."

"This possibility is not high." Yuan Ran said firmly this time, "It takes time to assimilate a genius with the same cultivation level. Even if Liang Muheng has been assimilated by Monroe, because the time is too short, he still needs to adapt to his new body and cannot spare the energy to assimilate other cultivators. My guess is that Chai Chengyun should find a place to break through. Liang Muheng is either trying to adapt to his body or find a place with no one around to assimilate by force."

"There's something I don't understand." Gao Han said, "Why can the demon's spirit assimilate humans?"
