Within the Heaven Fragrant Pavilion, the fragrance of sandalwood wafted in the air. The atmosphere was very quiet, giving people a sense of peace and harmony that separated them from the rest of the world.

Around the sandalwood table, there were several large teacher chairs. Directly facing the sandalwood table and chairs was a transparent crystal wall, and through the transparent crystal wall, one could clearly see the huge stage below.

"Young Master, young lady, please take a seat." Tang Luo moved Xia Xing and Lan Yi to the teacher's chair. While taking care of himself, he sat on the other side of Xia Xinghe and introduced it to Xia Xinghe: "This crystal wall has gone through a special process, it can be seen from the outside inside, but not the inside. Moreover, each room has its own corridor that allows one to leave the Gold Sale Cave without encountering anyone.

In the Fragrant Sky Pavilion, Tang Luo had just finished speaking when a white-bearded old man dressed in black walked up to the stage on the first floor. His eyes were narrow and long as he stared at the old man.

"Everyone, the Gold Sale Cave Trade Fair has officially begun!" The black-clothed old man said in a clear voice, "I, Tang Qi, do not like to be long-winded. Now, we will begin the trade for the first item: a middle grade spirit level divine weapon, the Burning Spear. The starting price is ten spirit level middle grade spirit stones, or a hundred spirit level low grade spirit stones.

After he finished speaking, Tang Qi shook his hand. A crimson spear that seemed to be wrapped in flames appeared in his hand.

The moment the fire spear appeared, waves of shouts, one after another, were immediately emitted from the originally silent Gold Sale Grotto …

"I bid twelve pills!"

"I am willing to use my family's high-grade Spirit Level Martial Skill, Divine Sword Technique, to exchange for it!"

"I have one hundred and thirty low-grade spirit stones here. Can I exchange them?"

Ten low-rank soul stones could be exchanged for one mid-rank soul stone. Similarly, ten mid-rank soul stones could only be exchanged for one high-rank soul stone. On the surface, the one who gave out one hundred and thirty low-rank soul stones seemed to have an advantage over the twelve mid-rank soul stones.

The Heavenly Palace Mirror martial artists mainly used spirit lower grade spirit stones. The Heaven's Expanse Mirror martial artists were more suited to using spirit middle grade spirit stones, mainly because the spirit stones of different grades all contained different amounts of spirit energy.

To a Celestial Mirror martial artist, this was a good deal. But to a Celestial Mirror martial artist, this was a loss.

On the surface, it seemed like a bit of a loss, but carefully thinking about it, there must have been a lot of people who had learned this technique, and even if this technique was traded to the Gold Sale Cave, the family would still have a copy of it, but this was the only one and it was not a loss at all. This was the reason why the Gold Sale Cave would ask for at least a high-grade Spirit level technique.

Shouts came from all directions around Xia Xinghe. It was obvious that the guests from the public area on the second floor and the guests from the independent area on the third floor were here.

"This crystal wall can't obstruct one's line of sight, and similarly, it can't obstruct sound. However, if you were to speak in a low voice like us, no one would be able to hear you." Tang Luo was very satisfied with the setting up of the Gold Sale Cave. He couldn't help but reveal a proud smile. However, when Tang Luo stole a glance at the drowsy Xia Xing, his pride was completely shattered.

"Young master, are you interested in this Divine Weapon?" Tang Luo didn't give up as he asked Xia Xinghe in a soft voice.

"Trash." Xia Xinghe's eyelids twitched as she glanced at the tea set in front of her.
