The slightly old wooden door opened, revealing a man's face. After silently looking at Mu Li and the other two, he opened the door and put the three in.

As soon as he entered the door, Mu Li felt a spiritual force above the Gu Ling Realm sweep, but the other party had no malice and quickly retreated.

However, although the man who opened the door only had the middle stage of Tianling cultivation, he still looked dull and didn't look strange when facing Zhao Lei's solid spirit realm.

"Entry fee for ten gold coins per person. This mask communicates with local formations, which can prevent others from exploring them. Please return them when leaving." The man directly handed over three masks with faint waves of formations, and said in a slight tone, and I don't know how many times I have said it.

Zhao Lei seemed to have known about the man's reaction for a long time. He put down thirty gold coins and took Mu Li and the others directly into it.

Without waiting for the three of them to take a few steps, the originally dim room suddenly changed, and a huge, wide and bright street suddenly appeared in front of the three of them.

This is an underground street hidden among many houses. Although it is covered by roofs, various lighting tools make it still like daytime.

Mu Li looked at the change of the scenery beside him, and when he turned around, he realized that the three of them had just passed some kind of hidden formation. It was the existence of this formation that prevented the place from being noticed by the outside world.

"I heard that this is a top spiritual-level formation derived from the Xuan-level magic array. Although many of the abilities have been weakened and canceled due to the high cost and maintenance costs, the hiding ability is top-notch." Zhao Lei took the initiative to explain when he saw Mu Li's unexpected expression.

The street is very large, and it occupies the spirits entering from other places. Everyone has masks on their faces and is constantly talking to masked people setting up stalls everywhere on the street.

Thinking of the man's words before, Mu Li's mental power was released, but he found that when he approached Zhao Lei and Qian Qianqian, he was isolated by an invisible formation force.

"There are all kinds of shameful transactions in this black market, and there are also strong people behind the scenes to take care of them secretly, so don't do things that are eye-catching." Zhao Lei stared at the two of them and warned them very seriously.

Seeing that both of them responded honestly, Zhao Lei then stepped forward and said to Mu Li: "Today I mainly bring you here to see it, get familiar with it, you should be able to use it in the future. Moreover, the shopkeeper also said that if you have anything you like, you can buy it for you."

"What about me?" Qian Qianqian, who had already become excited, said immediately as if she was pleased without waiting for Mu Li to answer.

"You... your father said too, you can only look at it and not buy it."

Zhao Lei looked at the spoiled girl and shook his head and joked: "This is the order given by your father, I dare not disobey it."

"What father's order is just worrying about his wallet! He's so stingy." The girl muttered dissatisfied.

The man didn't reply and walked on his own, followed by Mu Li and the others looking around.

Just as Mu Li looked at the strange things around him, Old Yu suddenly heard his mind: "Boy, you are lucky, there is something good next to you."

Mu Li looked slightly stunned, then his mental power searched and searched the things in the stall.

"Oh! This little brother is interested in something, so why not come and take a look." When someone noticed him, the originally silent vendor said.

There were many strange spiritual objects placed in front of this man’s stall, and a few of them were recognized by Mu Li, but they were all valuable things.

Although this man couldn't feel Mu Li's strength, he guessed that Mu Li was not old, thinking that he was following his elders to watch the fun, so he looked at Zhao Lei who was following him.

"How to sell this?" Following Old Yu's advice, Mu Li picked up a piece of black spiritual wood and asked in a faint tone.

"The little guy has a good vision. There is a spiritual fetus in this black heart wood. When you refine your own spiritual treasure in the future, it is a good material. I think you are destined to be with me. Five hundred low-level spirit stones will be sold to you at a cheap price." The man in a gray robe said in a gentle tone.

"Spirit Stone..." Mu Li couldn't help but look at Zhao Lei behind him when he heard this price.

After the spiritists advanced to the Guling Realm, they almost used spirit stones to replace them in both cultivation and trading.

However, Mu Li has not yet advanced. He is in the Tianling Stage, except for using it when setting up a formation, he usually does not use spirit stones, so he doesn't have much on his body.

"Oh! It does contain a spiritual fetus. This precious material for refining spiritual treasure weapons is no less than a thousand spirit stones. Fellow Taoist is so generous!" Zhao Lei stepped forward and looked at the things in Mu Li's hand, and said in a breathless voice.

"Hahaha, it turns out that he is an expert, so I won't hide it. This thing does contain a spiritual fetus, but it's a bit abnormal. But it's okay to use it to refine ordinary spiritual treasures, otherwise I wouldn't have put it out, and it's priced at a price of 400 spirit stones. How about it?" Hearing Zhao Lei's mouth, the man in gray robe did not delay, and his tone changed and offered a price again.

Zhao Lei did not respond immediately, but looked at Mu Li again. The situation was obvious now, so he was waiting for his final decision.

"I don't have enough spirit stones, so please pay for it." Mu Li said after hesitating.

"Okay, keep it in the account." Zhao Lei didn't persuade him and said casually.

After the transaction was completed, Zhao Lei didn't ask anything and stepped forward to take the two of them around again.

"Old Yu, why are you buying this?" Mu Li asked the old man in confusion.

Mu Li didn't know anything about this black heart wood or spiritual fetus. The old man always urged Mu Li to buy it quickly.

"Boy, don't you believe me in this tone? Is my vision not as good as these two juniors?" the old man said in a deep voice.

"Of course I don't know what this is. I'm just not sure what this is. Please help me solve my doubts." Mu Li had already gotten used to the old man's temper and asked along.

"Hmph! Don't you want to upgrade your Liyu Sword to a spiritual treasure? This is the best spiritual fetus. With it, let alone a spiritual treasure, it is possible to cultivate sword spirits in the future, and it is possible to advance the mysterious weapon." The old man said confidently.

"Is the best spiritual fetus not a broken thing?"

"Of course, these two kids are unaware of it, and you are free to get it. This spiritual fetus should have evolved for a short time and it will take another year or two to stabilize, which is also your luck."

"When the spiritual fetus is stable, and the top-level materials in my storage ring are added to make your Li Yu Sword a natal spiritual treasure. In the future, after you advance to the Gu Ling Realm, you can add some power to it." The old man planned with satisfaction.

Unlike the old man's idea, Li Yu Jian is Mu Li's sustenance to miss Mu Xiaoyu. Even if he really can't use it in the future, he will carry it with him. He didn't care how powerful he could become in the future.

The three of them walked forward for a while and came to a shop. After Zhao Lei looked at it, he took Mu Li and the others into it.

"This is a place for sale of information. As a new disciple of Taixuan Academy, you will have an opportunity to enter the private secret realm of the academy and you can take the opportunity to find some great opportunities."

"And such places often collect and sell related information, which will be useful to you at that time." Zhao Lei whispered to the clerk, then turned around and explained to Mu Li.

"Secret Realm, what is that?" Mu Li heard of this for the first time.

"This Taixuan Academy is located outside Nanli City and occupies a large area, including a stable small space secret realm, which contains the academy's background for many years and can be regarded as the real core area of ​​the academy."

"It is said that some things in this secret realm were left behind by powerful men from the Taixuan Dynasty when they were established. Therefore, in normal times, no one can get close to this secret realm except the core existence in the academy."

"However, after recruiting new disciples every year, everyone will be allowed to enter and ask everyone to search for opportunities. I heard that some people have had great opportunities in the past." Zhao Lei looked around, approached Mu Li's ear, and whispered.

"So that's how it is." Thinking of the behavior of major forces these days and hearing Zhao Lei's explanation, Mu Li had some understanding of the background of this academy.

No wonder people from other forces will also participate in this academy. It turns out that what we are looking at is not only the background behind him, but also the various backgrounds left by the powerful background.

After paying dozens of low-level spirit stones to buy a booklet, Zhao Lei took a casual look and handed it over to Mu Li again.

"Taixuan Academy has many rules, and this opportunity is very rare. If you miss it, it will be difficult to have such an opportunity again in the future. Go back and study and prepare carefully, and strive to gain something when the time comes." Zhao Lei said with a slightly cautious tone.

After helping Mu Li to acquire related news, Zhao Lei also completed Qian Qianjin's task, and then took the two of them to wander around the black market. Later, he bought a few spiritual objects for himself, which also added a lot of insight to Mu Li and the other two.

When the three of them walked out of the black market, they found that most of the day had passed without realizing it.
