It turned out that this "Earth Skin Crystal" was specially explained by Master Chi, and it was one of the best main materials for refining Heaven Rank equipment, which was even better than the Xuantie Crystal.

It's just that this "ground crystal" hidden deep underground is difficult to find. And they are very small, each one is only the size of a thumb, similar to the "chicken pen" fungus on the earth in Li Rui's later life.

Obviously, the chicken pen skin cannot be compared with the "ground skin crystal", the former is only a kind of fungus food, which can be found after heavy rains in summer.

In order to collect all the "Earth Crystals" that could refine a heaven-level cloak, Li Rui could only continue to dig wildly.

Gradually, the Ghost King Boss and the other ghosts also understood that this human kid who dared to love didn't come in to look for an opportunity to advance to the True Martial Realm, but simply came to find refining materials.

In order to get this human kid out of here as soon as possible, the ghost boss had to bite the bullet and shout from afar: "Boy, aren't you digging deep pits here everywhere just to collect all the materials for refining Heaven Rank equipment?"

Li Rui straightened up in the deep pit and asked in a loud voice: "Why are you going to help me? But don't you hold a grudge against me when I killed so many of your little brothers?"

"Hold a grudge!" the ghost boss roared in anger, "I want to suck your blood and eat your flesh, but my brothers and I still have to live, and it won't do us any good to interfere with you like this." ”

When Li Rui heard this, he thought that it would be easy for the ghost who was familiar with the situation here to help him find materials, so he smiled knowingly: "Smart, the so-called person who knows the times is Junjie, let's say, how can you help me?"

"You can help, but you also have to promise us one condition. ”

"On what terms?"

"Get out of here as soon as possible. We've been seeing that damn gadget swirling around your head all day long, and it's upset. ”

"Well said, but you have to promise me one condition. ”

"I'm so angry, I'll help you find the Heavenly Rank materials, and I have to promise you a condition, is there any Heavenly Reason?"

"Why don't you listen to it?"

Say. ”

"I found out that the so-called opportunity to find the advanced True Martial Realm is to be able to withstand your harassment, so what about ......it?"

"So what?"

"Help me harass the Wolf King, I also want it to advance to the True Martial Realm. ”

"No way. ”

"How could it be?"

"It's not a human being, it will automatically upgrade when it cultivates, and it's still far from being similar to the Nine Layers of the Acquired Realm of Humans, how can we help?"

"You can help. ”

"Can't help. ”

"As long as you can find a lot of earth-level and heaven-level food, and even mountain treasures, and let it eat wildly, won't you be able to promote quickly?"

"I'll go, you kid is really whimsical, you think that the earth-level food, the heaven-level food, and even the mountain treasures are cabbage in the vegetable market, let me tell you, you have been digging around for the past few months, almost all of them have been dug up, where did we find it?"

Li Rui lowered his head and pondered, thinking about it, it is impossible to grow to the earth level and the heaven level without thousands of years, especially some rare and exotic fruits, but he didn't dig much.

Helpless, Li Rui could only ask them to help him find the materials for refining equipment first.

Seeing that Li Rui had promised, the ghosts who had disappeared would leave here as long as they could help him find all the materials that could be used to refine a set of heaven-level equipment other than weapons, and they buzzed around pointing them to Li Rui.

It turns out that they are too familiar here, not only on the surface, but even more so deep underground.

Li Rui was crazy, he couldn't imagine that just relying on the deterrent power of the black box, these ghosts could help him find materials. However, it is easy to find materials, and it still needs to be dug up, and the ghost can't dig deep into the ground, so Li Rui can only dig it himself.

This Li Rui didn't care, as long as he could collect all the materials, he would be satisfied.

With the help of the ghost, Li Rui only needed a few days to dig up all the heaven-level materials, but the pale golden corpses, the ghost didn't help him find one, according to the ghost, most of these pale golden corpses were peerless powerhouses 10,000 years ago, and they were worthy of respect......

Li Rui doesn't care, anyway, there are already seven or eight in the Jade Tiger Ring, and I don't know if it will be useful to Master Chi.

And as soon as he collected the materials of the Qi Heaven Rank, the ghosts urged him to quickly fulfill his promise to leave the secret realm of the Dynasty, Li Rui counted the days, and there were months, and he also wanted to go to see the master and them, I don't know what the Moon Sect was doing.

When he came out of the Illusory Gate, the two old guys sitting at the entrance of the Imperial Dynasty's Secret Realm rolled their eyes in fright, almost treating Li Rui as a fraudulent corpse, because no one had ever been in for such a long time.

However, when they sensed that Li Rui's body had no fluctuating aura, they were relieved, and it seemed that Li Rui had consolidated the new realm inside.

It is also unheard of to be able to consolidate the True Martial Realm in a few months, and they are convinced that Li Rui's martial arts cultivation talent is not like what Master Chi said, he only has an orange level, but he is afraid that the green level will not be able to compare!

Master Chi waited for Li Rui outside the entrance, he felt that Li Rui was a lucky person and would not die in the secret realm of the dynasty, and sure enough, Li Rui really came out after advancing to the True Martial Realm.

Li Rui wanted to ask his master what was going on with the Moon Gazetteer, but he hurriedly said to Li Rui that he couldn't leave the palace now, the current imperial city, the dark waves were surging, and I didn't know how many masters had gathered to eat Li Rui, the old monster of the mineral crystal spirit object, especially the true martial realm hidden in the shadows.

Li Rui knew that this was all provoked by the aura of the mineral crystal spirit in his body.

Master Chi led Li Rui to his cultivation palace, and then told him about Liu Siyuan's Moon Sect, since Liu Siyuan announced that Li Rui was his disciple, many young people in the imperial city joined the Moon Sect in the name of Li Rui.

However, as the rumors of him being an old monster of mineral crystal spirit creatures spread to the imperial city, especially when the masters from all sides gathered, many of these new disciples also broke away from the Mochizuki Sect.

But no matter what, the Mochizuki Sect is now considered to have a foothold in the Imperial City, after all, there are some new disciples.

Facing Master Chi, Li Rui didn't hide it, and directly took out the various heaven-level materials he had collected from the Jade Tiger Ring. Master Chi had long suspected that this Jade Tiger Ring was a space ring, but now his mind was not on this, he was concerned about how Li Rui could dig up so many materials alone.

What particularly shocked Master Chi was that there were thousands of Xuantie crystals, a small pile of sky-high earth crystals, and the most unbelievable thing for him was that Li Rui could still dig up seven or eight pale golden corpses.

It turned out that this pale golden corpse was the only main material for refining the Heavenly Rank Trap Dove!

Master Chi sent someone to inform Liu Siyuan that his disciple Li Rui was not dead, and he had successfully advanced to the True Martial Realm and came out of the Imperial Secret Realm safely, in order to avoid trouble, he also asked Liu Siyuan not to go back to the palace.

In the cultivation hall of Master Chi in the Imperial Palace, Master Chi helped Li Rui refine the Heaven-Rank Equipment and the Heaven-Rank Organ Dove, and at the same time taught Li Rui the way of refining weapons, especially the way of sealing.

As for the earth-level iron ores, earth-level, heaven-level mountain treasures, and rare and exotic fruits that Li Rui brought out from the secret realm of the dynasty, Master Chi instructed a few disciples to either exchange them for golden tickets, or ask the alchemy masters in the imperial city to help Li Rui refine the earth-level pills.

It turned out that there was not a single Heaven Rank Alchemy Master in the entire Dynasty, so even if there were Heavenly Rank Mountain Treasures and Rare Fruits, they could only refine the Nine Turns Qi and Blood Pill to the top of the Earth Rank......
