This cave is actually a very old cave.

When Zhang Hong entered this cave, he could feel the rich aura in the cave.

In the cave, there are also some fireflies with wings growing.

These fireflies are not aggressive and glow from their bodies.

In this way, the entire cave becomes transparent and bright.

Zhang Hong and Tang Xiaoyue walked in it without any obstacles.

Tang Xiaoyue is just a twelve or thirteen-year-old girl, walking in front, but jumping and jumping, which can be described as innocent.

Zhang Hong followed behind Tang Xiaoyue, feeling Tang Xiaoyue's innocence, and feeling like he had returned to his childhood.

The two of them walked for about half an hour before they came to a hall in the cave.

This is the heart of the cave.

A figure, like a withered tree, wrapped in a large robe.

It looks like a shriveled corpse.

If it weren't for the spirit of his body, Zhang Hong would have thought that he was a dead man at this time.

Seeing such a person, Zhang Hong's heart couldn't help but shudder.

Zhang Hong also guessed that this person might be Tang Xiaoyue's grandfather.

"Xiao Yue, you're back!" The old man who described the withered old man suddenly opened his eyes, and his eyes were shining.

"Well, grandpa, I'm back. Tang Xiaoyue walked to the old man's side.

"Why did you bring outsiders here, didn't I tell you that I have to hide the alchemy here?" the old man asked.

"Well, grandpa, this is Brother Zhang Hong, Brother Zhang Hong saved my life just now. Tang Xiaoyue said.

"Hello, this old gentleman!" Zhang Hong mocked the withered old man and bowed, and then used the system to scan the withered old man.

Zhang Hong suddenly discovered that this withered old man turned out to be a powerhouse of the Spirit Dao Divine Realm.

The four realms of the spiritual path are the spiritual base realm, the Jindan realm, the Yuan Shen realm, and the transformation god realm.

The realm of transformation is the highest state of spiritual cultivation.

On the Guizang Continent, there has ever been the strongest cultivator, and that is only the Jindan realm.

Now, due to the degradation of the Longyuan Secret Realm, it is also impossible for the Jindan Realm powerhouses to appear in the Guizang Continent.

That is to say, the cultivation of this withered old man is an unrivaled existence.

It's just that the withered old man's body seems to have been invaded by some virus, and the blood and qi all over his body seem to have been drained by something, so that there is no blood at all on his body, like a skeleton.

When ordinary people saw this withered old man, they thought they had seen a dried corpse.

"Boy, my Xiaoyue is just a simple child, you say, what is the purpose of you deceiving her?" asked the withered old man.

Hearing the cool old man's words, Zhang Hong was also stunned.

"I, Zhang Hongxing, sit upright, what did I lie to a little girl, old man, let's speak with our conscience, besides, Miss Xiaoyue was chased and killed by the people of the Five Poisons Sect, so it was indeed me who helped. Zhang Hong said.

"Grandpa, what Brother Zhang Hong said is true, he didn't lie to you!" said the little girl.

"Well, the rules of my ancient Tang Immortal Sect have always been revenge, since you saved Xiaoyue, then what do you want in return!" the old man asked.

"Hehe, I heard that Old Man Tang and Miss Xiaoyue are both from the world of the Guizang Continent, and there are many high-level spiritual veins in the world over there. Zhang Hong asked.

"Really?" said the old man, nodding his head.

"In that case, the old man should have a lot of materials brought from the Shenghan Continent. Zhang Hong said.

"That's right, you want the materials I brought from the Shenghan Continent?" the old man asked.

"If there is, I want some spirit jade, preferably the best kind of spirit jade," Zhang Hong said.

"Well, if you want the best spirit jade, could it be that you still want to refine what kind of top spirit array can't be?" The old man stared at Zhang Hong with his eyes, and he wondered for a while.

"Boy, I'm a refining array master, and I'm trying to refine some top-grade spirit arrays. Zhang Hong explained.

"But as far as I know, on the Guizang Continent, the strongest cultivator is only the ninth level of the spirit base, you actually want to refine the best spirit array, your greed is not small!" the old man said.

"Hehe, I'm really greedy. Zhang Hong said.

"Boy, I have some spirit jade in my hand, since you want it, I can give it to you, but I don't have this top-grade spirit jade, but I have four pieces of high-grade spirit jade. The old man said.

"Well, it doesn't matter, as long as it's a high-grade spirit jade!" Zhang Hong said.

If you have spiritual jade, you can use spiritual jade as the core material to condense the spiritual array.

The spirit array is more powerful than the magic array, and Zhang Hong's Qilin Blood Fury Array, although it is strong, is only a magic circle after all.

If Zhang Hong can Zhang Hong's powerful spirit array, then Zhang Hong can have a more powerful array ability.

At this time, the old man's hand moved, and he even put out four pieces of spirit jade.

This piece of jade is very aura, and it seems to be an excellent spiritual jade.

These four pieces of spiritual jade, one fire genus, one earth genus, one water genus, and one metal genus.

Zhang Hongke was also unceremonious, even if he took all these spiritual jades into his pocket.

"I don't know if the old gentleman has a medium-grade spirit jade. Zhang Hong asked curiously again.

"Boy, you're a bit greedy!" said the old man.

"Hehe, this is not greed, I want these high-grade spirit jades, if there is no medium-grade spirit jade as auxiliary materials, I am afraid that it will be difficult to condense the formation. Zhang Hong said.

"Well, actually, the medium-grade spirit jade belongs to the tenth-level material, and you don't need to ask me. The old man said.

"Don't you need to ask for you?" Zhang Hong was stunned.

"I know that. Tang Xiaoyue squeaked and laughed.

Zhang Hong was stunned, and he didn't know what Tang Xiaoyue meant.

"Brother Zhang Hong, come with me!" Tang Xiaoyue said.

At that moment, Tang Xiaoyue was leading Zhang Hong to a place.

was guided by Tang Xiaoyue, Zhang Hong actually came to a secret room.

Seeing the situation here, Zhang Hong was also stunned for a moment.

This secret room is a treasure trove.

"In this secret room, there are all kinds of materials, the materials here are all materials of the ninth and tenth levels, what kind of medium-grade magic jade and low-grade magic jade does Brother Zhang Hong need, there should be all here. Tang Xiaoyue said.

"Really!" Zhang Hong nodded.

"Actually, this cave mansion is originally an immortal cultivator's cave mansion, and this treasure house here was left by an immortal cultivator who cultivated here before. Tang Xiaoyue said.

"Don't you want the wealth here?" asked Zhang Hong.

"These materials here are all ninth-level and tenth-level materials, and in our Ancient Tang Immortal Sect, they are not anything valuable, and my grandfather and I are not interested in this. Tang Xiaoyue said.

"In this way, you don't want any of these things. Zhang Hong asked.

"That's right, my grandfather and I really don't want these things. Tang Xiaoyue said.

"Since you don't want it, then I'll take it all. Zhang Hong saw the boxes of materials in front of him, and he also became a little greedy.

"Brother Zhang Hong wants it, and there is no problem. Tang Xiaoyue said.

"In that case, then you're welcome. Zhang Hong said.

Zhang Hong's systematic material library can collect materials endlessly.

Zhang Hong was also unceremoniously, and immediately his mental power moved, and the materials of the Quartet continued to pour into Zhang Hong's mind.

After about a while, Zhang Hong finally included all the materials here in his system material library.

It can be said that when Zhang Hong came to this cave, he gained a big harvest, and he would not run in vain.
