Red light flashed, white gas swirled.

It took half an hour for the white gas to slowly dissipate.

Zhang Delong removed the protective light shield, looked up, and was immediately overjoyed, the stone door had been opened, and colorful lights kept flashing behind the stone gate, "Are there a lot of treasures in the stone gate?" Zhang Delong came to Lin San's side in a few steps, and then looked towards the stone gate, his eyes suddenly widened, good guy! Inside the stone gate is a sealed secret room, and the secret room is full of things, spirit stones, ancient treasures, and spirit grass...... It's a treasure trove, Zhang Delong just wanted to raise his feet to enter, but was stopped by Lin San.

Zhang Delong looked at Lin San suspiciously, and there seemed to be a trace of caution in the depths of his eyes.

"Don't be fooled by superficial phenomena, those spirit stones and ancient treasures are illusions. Lin San said expressionlessly.

"Illusion, impossible, right?" Zhang Delong was a little unconvinced.

Lin San raised his hand and threw out two red big knives, which slashed directly at the spirit stones and ancient treasures.

"Hey...... Be careful...... Don't break the spirit stone...... Uh......" Zhang Delong's eyes opened suddenly, his face showed a trace of incredulity, under the bombardment of the two red big knives, the spirit stone and the ancient treasure and the spirit grass actually shook, as if a horizontal plane was shaking, it was really an illusion, Zhang Delong's face sank: "I dare to play with me! I won't smash you after reading it!" As he spoke, Zhang Delong sacrificed several magic weapons, and frantically smashed the spirit stones and ancient treasures in the stone room.

Under the joint attack of Lin San and Zhang Delong, the illusions such as Spirit Stone and Gu Bao were quickly shattered.

As soon as the illusion shattered, the real scene behind it was revealed, and it turned out to be a large black stone, these stones were plain and bland, and no trace of spiritual power could be felt.

"What is this?" Zhang Delong stretched out his hand and picked up a black stone and looked at it carefully: "Black gold stone, this is actually black gold stone!"

"What is Black Lazuli?" Lin San heard the name Black Lazuli for the first time.

"Black Lazuli is a very hard stone, it is said to be harder than meteoric iron, and it is something that many refining sects dream of. Zhang Delong's face was full of excitement: "If so many black gold stones are taken outside, it is estimated that they can be sold for a large sum of spirit stones." ”

"Harder than meteoric iron?" Lin San was a little unconvinced, and reached out his fist and smashed it the black gold stone.

"Bang!" the black lazuli flew out, and there was not a single scar visible on the surface.

Lin San didn't believe in evil, so he transported seven layers of mana and gave the black gold stone a blow.

The black lazuli is still intact.

"This black lazuli is really hard and ridiculously hard. Lin San secretly thought: " If the black gold stone is integrated into the Demon Demon Knife, it is estimated that the strength of the Demon Demon Knife will be on a higher level, and it seems that the Thunder Demon Bee is also very interested in these black gold stones, originally, Lin San did not find the hidden stone door behind the stone wall, it was the Thunder Demon Bee in the spirit insect bag that suddenly became irritable, after this period of contact, Lin San knew very well that whenever the Thunder Demon Bee became irritable, it means that they found something of interest, and what can make the Thunder Demon Bee interested must be some cherished treasure, such as magic weapons, ancient treasures and the like.

After Lin San searched carefully, he finally found the secret room hidden behind the stone wall.

"Uh...... That, Lin Daoyou, I also helped attack those illusions just now, and I also calculated a point of strength, that black lazuli ......" Looking at Zhang Delong's expression, it seemed that he wanted to divide some black lazuli.

Lin San shook his head: "These black gold stones can't be given to you." ”

"Ahh

"Zhang Daoyou, don't be angry, I have a lot of use for these black gold stones, so I can't give them to you, but ...... I can compensate you for the spirit stones. Lin San threw Zhang Delong a storage bag: "There are one million middle-grade spirit stones in here, I don't know if it's enough?"

"Oh, I'm so embarrassed to ask for your spirit stone. Zhang Delong pretended to excuse himself.

"If you're a friend of mine, put away the spirit stones. "To tell the truth, Lin San is also a reasonable person, just now Zhang Delong also made efforts to attack the illusion formation, and he should have divided some black gold stones, but Lin San didn't want to divide the black gold stones, so he directly gave the spirit stones to compensate.

In fact, Zhang Delong also sold the black gold stone when he got it, and now he can get the spirit stone directly, he must be willing in his heart, not to mention, the spirit stone given by Lin San is not small.

As soon as Lin San rolled up his sleeves, he put all the black gold stones into the storage ring, and just when Lin San was about to leave the secret room, he suddenly saw a black wooden stick left in the corner of the secret room, this wooden stick was very ugly in shape, and it looked like an ordinary wood at first glance.

Zhang Delong also found the wooden stick: "How can there be a wooden stick here?"

Lin San stretched out his hand and sucked the wooden stick, turned it over and looked at it several times, and there was no trace of spiritual power fluctuation detected on the wooden stick, it was just an ordinary piece of wood, but Lin San was a little puzzled in his heart, how could an ordinary piece of wood appear in such a secret room? Perhaps, this piece of wood was a treasure, but he couldn't recognize it because of his shallow cultivation! Thinking of this, Lin San casually threw the black wooden stick into the storage ring, planning to study it slowly when he had the opportunity in the future.

"Lin Daoyou, there is nothing left here, should we go to the fifth floor to take a look?" Since the discovery of the black lazuli, Zhang Delong's heart began to itch, and he couldn't wait to go to the upper layers immediately to take a look, hoping to find some treasures to cherish.

Lin San nodded, and followed Zhang Delong up the stairs to the fifth floor.

The fifth layer is some rare refining materials, each refining material is wrapped in a layer of gray light mask, roughly counting, the entire five layers can have hundreds of gray light masks, more than half of which are empty.

"It's really strange, why haven't all these rare materials been taken away?" Zhang Delong said puzzled.

Lin San pointed to the stone wall opposite: "Look at what is written on it." ”

Zhang Delong looked in the direction pointed by Lin San, and sure enough, he saw a line of words written on the stone wall: "Each person can only take one piece of refining materials here, and if you take one more piece, you will be immediately teleported out of the Xiaoyao Palace...... It turns out that there is a limit, no wonder so many materials are taken by each person. ”

Lin San looked around, then chose a crystal clear jade.

Zhang Delong chose a thousand-year-old crocodile skin, planning to take it out to refine a defensive armor.

After the two of them finished selecting the materials, they went directly to the sixth floor.

Unexpectedly, the sixth floor was quite lively, Wang Dashi, Sai Jinhua and others were there.

Lin San said hello with a smile, but no one paid attention to him, Lin San was stunned for a moment, only to find that the atmosphere at the scene was a little wrong, and it seemed that everyone had a murderous aura on their faces.

"Gu Bao!!" Zhang Delong suddenly exclaimed.
