However, when one of the people saw this crystal clearly, their faces under the mask were a little weird, and their eyes flashed at the same time. This person was Li Si. If he read it correctly, the soul crystal was clearly the sapphire he had dug out of the puppet's chest in the passageway.

Of course, now he also knew that this was not called sapphire, but called soul crystal. Li Si thought about it thoughtfully, and he was considering whether to exchange with Zuo City Lord.

At that time, he didn't know what it was, so he just put it away temporarily. Unexpectedly, it was a rare crystal that was only known as the legend. It was indeed rare. After a while, only one monk hesitantly took out a piece and stepped forward to change a set of array flags.

After asking a few more questions, the Lord Zuo City asked, and saw that no one came up again. Although he was mentally prepared, he couldn't help but feel disappointed. Lord Zuo City sighed secretly and was about to put away the formation plate and the formation flag, but one of them suddenly stood up.

This made Lord Zuo City excited and looked at the person in surprise and said, "Fellow Taoist, do you have soul crystals, too?"

The person who stepped forward was Li Si. He flipped his palm silently and a blue crystal appeared in his hand. However, this crystal was much larger than what the Lord Zuo City took out, and a ball of five-colored spiritual energy emanated from the crystal.

Lord Zuo was stunned at first, then looked at Li Si in surprise: "I didn't expect that the soul crystal this fellow Taoist took out was so big. In this way, you can choose two sets of array flags or array plates from it."

"Two sets?" Li Si smiled slightly and shook his head.

"What? Do you think it's too little? I don't know how many friends plan to exchange for?" Zuo City Lord was not angry and asked angrily.

"This soul crystal is exchanged for all the formation flags and formation plates of fellow Taoists." Li Si said calmly.

"What? Don't you think you're too greedy?" Zuocheng Lord frowned and said with some dissatisfaction.

Li Si curled his lips. Although he didn't know much about the functions of these soul crystals, he also knew from the attitude of the Lord Zuo City, these soul crystals must have great effects. Moreover, judging from the spiritual energy emitted from the soul crystal, the larger the soul crystal, the purer the spiritual energy contained in it.

Therefore, although Li Si was a little confused, he still said calmly: "Haha! Lord Zuo City should know that this soul crystal is not just about the size of the soul crystal. As for whether to change it, it depends on Lord Zuo City. Besides, such a large soul crystal is..."

Li Si did not continue to say the following words. He deliberately deceived Zuo City Lord. Sure enough, as soon as his words fell, Zuo City Lord's face changed, and he looked at Li Si deeply.

Finally, Lord Zuo pondered for a while and said, "Okay, such a large soul crystal is indeed rare. I need this thing in urgent need, so let's exchange it as the fellow Taoist said!"

Lord Zuo said, and sighed, which made other monks think that Lord Zuo was in urgent need of this thing, so he accepted this exchange that seemed not very equivalent on the surface!

However, it is impossible to lose too much. The monks present couldn't help but look at the blue crystal. They could exchange for so many high-quality array flags and array plates, so they were not ordinary things.

Li Si didn't say anything else, but just calmly handed over the soul crystal, then lowered his head and flipped his sleeves, and put away the array flags and array plates. No one else noticed that when he lowered his head, his lips moved slightly a few times.

The Lord Zuo City's eyes shone brightly, and a trace of surprise flashed across his face, but Li Si did not stay much and turned back to his position.

Next, the Zuo City Lord announced the end of the trade fair, and everyone went downstairs to leave. Li Si naturally followed Elder Kuang and left Youranju. They didn't talk much when they left, and they slowly got closer and gathered together.

"Junior Brother Li, I have some private matters to deal with. What are the plans for Junior Brother Li? Should I go back to my residence to rest for a while, or go to other places to take a walk?" Elder Kuang asked after looking around.

"I need to buy some materials, so I plan to go to a few nearby markets. Maybe I will gain something." Li Si said with a smile without any intention of hiding it.

"Okay, let's separate here for the time being!" Elder Kuang agreed without any objection. It was not appropriate for Li Si to be present when the private matter he was about to be done.

So, Elder Kuang and Li Si immediately separated here and each started to act. Several markets in Fengtian City were very large. Li Si walked on a street in the southern part of Fangcheng City and kept looking at the shops on both sides.

He had been staying in the inn and not going out before because he thought that good things would stay after the trade fair officially began. Now the trade fair officially began tomorrow, so the things he put out at this time were quite good.

Li Si plans to buy some rare alchemy spirit herbs and prepare to refine some high-level elixirs, especially elixirs that improve the cultivation level of the Nascent Soul stage, Jinyuan Pill. Although he still has many spiritual herbs on him, refining Jinyuan Pills is too much useless for spiritual herbs, and the failure rate is also relatively high.

Moreover, it is rare to have such a big trade fair and the opportunity is rare, so it is better to prepare more. However, Li Si went to several shops in the market and only bought some auxiliary spiritual herbs, but he didn't buy any of the main medicines.

However, he also received news that the main medicine had to be purchased at the auction, after all, the value was not low. In addition to Li Si, other monks also entered and exited the shops on both sides, buying and selling what they wanted in different expressions.

Most of them are foundation-building cultivators, and occasionally a small number of elixirs appear. As for the Qi Refining Cultivators, in addition to the monks in Fengtian City, there are very few foreign Qi Refining Cultivators.

Even the Qi Refining Cultivation Cultivation Cultivation Cultivation Cultivation in this city mostly work in shops to help high-level cultivators, and their status was very low. By chance, Li Si actually met the two female cultivators who had glared at him in the inn before.

However, the woman was not among them, only the very beautiful female cultivator and the long-braided girl. What surprised Li Si was that the two girls actually followed the arrogant Shangguan Young Master, smiling charmingly.

In addition, the Shangguan Young Master was holding a female cultivator who was dressed very exposed in his left hand, followed by a group of servants. The group was so powerful that it was eye-catching.

However, it doesn't matter to Li Si. Li Si shook his head secretly and prepared to go to the next shop. Unexpectedly, as soon as he walked to them, he was stopped by the beautiful girl.

"Stop." The girl shouted maliciously.

"Oh? Are you talking to me?" Li Si raised his eyebrows and looked at the girl in surprise and said.

"Of course." The girl stared at Li Si with her eyes. Not to mention, she actually looked a little cute.

Li Si chuckled: "I wonder what's wrong with the girl calling to live here?"
