When everyone else was making fun of Lao Hu, only Xia Yu stared at the stone in Lao Hu's hand.

It is true that it is a stone in Lao Hu's hand, but the surface of this stone looks colorful, so it has another name, called the five-color stone.

Regarding the five-color stone, it is rumored that in ancient times, the material used by the female snail saint to refine the stone and make up the sky was this five-color stone.

The reason why Xia Yu stared at the five-color stone in Lao Hu's hand was because of the jade slip that Xia Yu got in the refining room on the second floor of the Immortal Mansion, which contained a description of the five-color stone.

However, the jade slip only said that the five-color stone is a treasure, which can be met but not sought, and as for the specific use, it is not detailed.

"Hu Daoyou, are you really willing to exchange it for a quenching pill?" Xia Yu asked at Lao Hu.

"I ......" Hearing this, Lao Hu was still a little hesitant.

"It's up to you to change or not, you have to think clearly. Seeing Lao Hu hesitating, Xia Yu had no choice but to say.

"Change, I changed. Lao Hu finally gritted his teeth and said.

"Are you sure you want to change it? You can't regret it? You don't know what it's used for, but it's a mystery about where it came from. Hearing Lao Hu agree to change, Xia Yu reminded again, lest he regret it again in the future.

"Since I'm sure, I won't regret it, but can I tell my seniors, what is this?" Lao Hu also wanted to know what he had picked up.

"Actually, you're a pebble. Xia Yu said.

"What, Master, since this is really a stone, what should we change? Hearing this, Da Bi said loudly.

"I'll just say it's a stone, as I expected, Lao Hu, you really have you, take a stone out and exchange it for a quenching pill." Someone continued to tease.

"That senior, I'm ......" Lao Hu couldn't help but tighten his face when he heard Xia Yu's words, thinking that he wouldn't change it.

"Don't worry, I'm not done yet, this is indeed a stone, but this stone has another name, called the five-color stone. That's right, it's the legendary five-color stone used by the female snail to refine stones and mend the sky, which is why I just said that its origin is mysterious. Xia Yu told eloquently.

"This stone is so mysterious, since it goes back to ancient times, hasn't it become an ancient treasure?"

"This old Hu can, I didn't expect that any stone could become an ancient treasure, why don't I have such luck. "The people who used to say that Lao Hu had poor vision began to envy again.

"Senior, what is the use of this five-color stone?" Lao Hu felt a little surging in his heart.

"Actually, I don't know what the purpose of this five-color stone is, except for the legend that the five-color stone has been used by the female snail saint to refine the stone to make up the sky, there is no legend about any other use, so this five-color stone is like chicken ribs, tasteless to eat, it is a pity to abandon it, do you understand?" Xia Yu said.

"Ah, in this way, these five-colored stones are no different from ordinary stones. After hearing Xia Yu's words, someone said.

"No, no, no, compared with ordinary stones, these five-color stones are still useful, at least they can be used as decorations, I think it's pretty good." Another said.

"Haha...... Fellow Daoist, your words are really interesting. When the others heard this, they couldn't help but laugh one by one.

Hearing everyone's laughter, Lao Hu, who was still in a surging mood, suddenly became bored again.

It's like holding your beloved ice cream, and suddenly it falls to the ground while eating it, and there is a piece of dog shit under the place where the ice cream fell, which is simply disgusting.

"Hu Daoyou, are you willing to exchange this five-color stone for the Quenching Pill?" When Old Hu was mourning for death, Xia Yu asked him.

"Senior, are you really willing to exchange with me for the Quenching Pill?" Hearing this, Lao Hu was a little incredulous.

"Yes, although these five-colored stones are useless, I like to collect these antiquities, so I am still willing to exchange them with you. Xia Yu replied.

"Change, change, I change. Lao Hu, who was secretly sad, immediately became happy and said.

It must be changed, and the fool will not change it, and it is better to keep this five-color stone that I don't know what the use is, it is better to change it to a quenching pill.

I saw that Lao Hu quickly handed the five-color stone in his hand to Xia Yu, and then took the last quenching pill in Da Bi's hand, as if he was afraid that Xia Yu would regret it.

In this auction, all the seven quenching pills brought by Xia Yu were exchanged.

Among them, five quenching pills were exchanged for the medicinal materials that Xia Yu needed, one quenching pill was sold for more than 10 million dollars, and one was exchanged for five-color stones, which was very fruitful.

And when he got the five-color stone handed over by Lao Hu, Xia Yu suddenly felt that there was a change in the immortal mansion in his body, just like the last time the immortal mansion absorbed the thousand-year-old red wood, and then Xia Yu found that the five-color stone in his hand had disappeared, and it seemed that it should have been absorbed by the immortal mansion.

But this time it's a little different from the last time.

Last time, the Immortal Mansion was directly promoted from the first level to the second level after absorbing the thousand-year-old red wood, but this time after absorbing the five-color stone, the level of the Immortal Mansion was not improved, but there were some changes.

It was the changes in the Immortal Mansion that made Xia Yu feel dizzy for a while, just like when the Immortal Mansion first came, Xia Yu was hit by the Immortal Mansion.

It's just that that time, Xia Yu was directly unconscious, and this time, Xia Yu was not unconscious, but at this time, Xia Yu's whole person looked pale, as if he had suffered a heavy blow, and he was a little shaky.

"Master, are you alright? Seeing that Xia Yu suddenly turned pale, Da Bi hurriedly supported him.

"It's okay, don't worry, I'll just sit down and breathe for a while. With Da Bi's support, Xia Yu found a place, closed his eyes and sat down.

In the eyes of outsiders, Xia Yu seemed to be cultivating and pranayama at this time.

In fact, Xia Yu was checking the changes in the Immortal Mansion in the sea at this time.

I saw that in Xia Yu's immortal mansion in the sea of knowledge, indescribable changes were taking place at this time, and it was this change in the immortal mansion that made Xia Yuru suffer a heavy blow.

However, the change in the immortal mansion did not bring substantial harm to Xia Yu, the reason why Xia Yu was pale was because the immortal mansion in Xia Yu's sea of knowledge was constantly changing at this time, and it was this change in the immortal mansion that made Xia Yu's sea of knowledge expand invisibly.

The expansion of a person's knowledge of the sea also indicates that the person's spiritual power has been improved.

And the changes in the Xianfu itself, Xia Yu also had a certain feeling at this time, if the previous Xianfu gave Xia Yu a feeling of ethereal existence, then at this time, Xia Yu found that after the Xianfu absorbed the five-color stone, the Xianfu seemed to have substance.

Whether this change in Xianfu is good or bad, Xia Yu doesn't know at this time.

Of course, this change in the Immortal Mansion is not something that Xia Yu can stop, Xia Yu can only go with the flow.

The changes in the Immortal Mansion did not last long, and the changes had been completed after a while, but at this time, Xia Yu looked like he had just recovered from a serious illness, and his face was pale.
