Each of the last five elixirs was sold at a gratifying price, and even the poisonous elixir without antidote was sold at a sky-high price. Su Ruoxi was very happy!

Among them, the finale Tianpin Qinghun Pill sold at the highest price in the audience tonight!

Not only Su Ruoxi was happy, but the auction was also very happy!

So, as soon as the auction ended, Mr. Cheng came to Su Ruoxi's private room in person!

"This is the spirit stone obtained from the elixir auction tonight. In order to show the sincerity of our auction house, we will not accept your rake. There are also two medicinal herbs that you auctioned, and the spirit stone has been deducted!" Cheng Lao said Then handed Su Ruoxi an ordinary space ring.

After Su Ruoxi took it, she swept her consciousness, and sure enough, the number of the two elixir plants and the number of spirit stones matched!

"The auction house also has rules of the auction house, and the fee that should be charged should still be charged!" Su Ruoxi frowned and looked at Cheng Lao.

She has nothing to do with Tianlou Auction House. Although she knows that the other party should guess her identity as an alchemist and do this because she wants to make friends, she doesn't really want to take advantage of others!

"Master, you're being polite. We also have selfish intentions. We hope that while we can make good friends with the master, we also hope that we can cooperate with the master for a long time..."

Mr. Cheng directly stated his intention for coming. First, he introduced the structure of Tianlou Auction House to Su Ruoxi in detail, and then expressed the sincerity of Tianlou Auction House!

The conditions offered by Tianlou Auction House were very good. Su Ruoxi hesitated for a while, thinking of her grandfather's Shangguan family, she finally agreed!

"Great, this is a special token of the Tianlou Auction House. It can be used in any Tianlou Auction House. There is a 30% discount for buying everything in the Tianlou Auction House. If you encounter trouble, you can use this token to Seeking the help and protection of Tianlou Auction House..." Mr. Cheng handed Su Ruoxi a purple token with the word Tianlou engraved on it.

This made Su Ruoxi slightly surprised, and had some ideas about the identity of Mr. Cheng!

"Hehe... this old man is the Great Elder of Tianlou Auction House, and this time I came here for the relic, so I help appraise the treasure!"

Probably seeing the doubt in Su Ruoxi's eyes, Mr. Cheng said directly.

"No wonder!" Su Ruoxi smiled.

"What's the master's name?" Cheng Lao looked at Su Ruoxi and asked.

"My surname is Su, so the master is exempt. Seniors can call me Su!" Su Ruoxi thought for a while and said.

"Su? Could it be from the Su family of the hermit family?" Cheng Lao asked in surprise.

In fact, he guessed that Su Ruoxi was from the Shangguan family of Yin clan!

After all, the Shangguan family is an alchemy family, so it is not difficult for a young Tianpin alchemist to appear!

But I didn't expect that the other party's surname was not Shangguan!

"no!"

"As for the promotion of my elixir when seniors want to auction it in the future, you can use this..." Su Ruoxi thought for a while and then took out a bottle of elixir and handed it to Elder Cheng.

Cheng Lao took it over and opened it suspiciously. After a burst of strong medicinal fragrance, Cheng Lao felt that his strength had improved slightly, and what shocked Cheng Lao the most was that there were almost 30 pills in this bottle, all of which were of heavenly grade. !

"Master Su, what are you?" Old Cheng looked at Su Ruoxi in shock.

Su Ruoxi smiled, and poured out one pill from the porcelain bottle, and in Cheng Lao's puzzled eyes, a trace of spiritual power emerged from his fingertips and slowly poured it into the pill, and then Cheng Lao was shocked to see the pill The word "poison doctor" floated out of it!

Until Su Ruoxi withdrew his spiritual power, and the word poison doctor slowly fell into the elixir and disappeared, Mr. Cheng didn't come back to his senses!
