Along the way, there were countless mechanisms and formations. If you were not careful, you might suffer casualties.

This was also expected. Before entering the underground palace, there was already a formation hidden and protected. Although Lin Yun stepped on it with one foot, if the formation exerted its power, even the Golden Pill monk might be killed. Because of this, Yang Xi and others were full of admiration for Lin Yun's ease to break the formation so easily.

Not long after, the group came to the center of the underground palace. The journey was full of dangers and finally survived. Compared to the others, Ma Wenwu was proud. He finally let go of his hands and cracked the mechanisms and formations in the underground palace passage. Only then did he unfold correctly, and even had resentment. If he had not recognized the formation outside, he would not have found the formation eye and would not have needed any medical saint.

Now, isn’t it up to him to work hard all the way to walk to the center of the underground palace? Ma Wenwu was a little satisfied. When he looked at Lin Yun, he found that the other party didn’t care at all. He looked like he was taking a leisurely walk. He was immediately annoyed and snorted coldly, but did not provoke again.

"This is the center of the underground palace. So, what about the perfect foundation-building technique?" Yang Xi and others were a little anxious. This was the main purpose of their trip.

Along the way, I also picked up a lot of treasures, such as pills and magic weapons. Everyone has a great harvest, and this is worthwhile. However, these can only increase combat power and have no effect on cultivation. They are all golden elixirs that have made breakthroughs in foundation building and have reached the end of their cultivation. Unless they find a perfect foundation building technique, refer to the secrets, and find ways to improve the abutment, they have hope of breakthroughs.

Once you break through, the strength you get is not achieved with the help of external forces, but the power you truly master. Moreover, once you break through, your life span will immediately soar. This is the most important thing. After all, in addition to being the foundation of your life, it is also the purpose of cultivators in pursuit of longevity.

"Where!" Yang Xi suddenly pointed ahead. There was a small palace. Judging from the gaps in the pearl curtain, there was indeed an extraordinary jade slip.

Even if it is not a perfect foundation-building technique, it must be extraordinary. After Yang Xi finished calling, he rushed over first. Ma Wenwu and others cursed secretly, but they were unwilling to fall behind and hurriedly followed. Yun Fan was about to move, but he also collected several items along the way, all guessing according to the preferences of the former medical saint, which might be something from a treasure.

As for the jade slip, I also wanted to see it, but when I saw Lin Yun still moved, Yun Fan endured it and stood beside Lin Yun.

Lin Yun looked at Yang Xi and others who were rushing over, and his lips curled slightly, and followed him. Yun Fan saw that Lin Yun had moved, so he followed.

Yang Xi and others rushed into the hall, and Yang Xi was the first to get the jade slip. However, Yang Xi did not check immediately, but looked at the person who followed in. When he saw that there were only Ma Wenwu and the other two, he frowned slightly without checking.

"Yang Xi, what are you waiting for? Look quickly. Is it a perfect foundation-building technique?" Ma Wenwu and others were a little anxious. If it weren't for Yang Xi who got the jade slip, they would probably not be able to help but snatch it.

Yang Xi said nothing when he heard this. When he saw Lin Yun and Yun Fan coming in, he breathed a sigh of relief.

"If you don't want to see it, leave it to us and let's check it out!" Ma Wenwu snorted coldly, his tone a little stiff, "Or, do you want to take it alone?"

Yang Xi's actions at this time were indeed suspicious. He was so concerned about the perfect foundation-building technique, but after obtaining the jade slip, he did not check it immediately. This made Ma Wenwu and others feel that Yang Xi regretted it and wanted to take over the perfect foundation-building technique.

After all, this is something that gives them hope to recast the abutment and go further. Moreover, after completing their own practice, they can also dedicate it to the corpus in exchange for resources. Maybe they can quickly break through the Nascent Soul and become a powerful man. It is not completely impossible to have greed and unwilling to share it with others.

"If you want to see it, I'll give it to you." Yang Xi didn't care at all and threw the jade slip to Ma Wenwu.

Ma Wenwu was stunned. After taking the jade slip, hesitated and activated his true energy again. He saw the records in the jade slip clearly, and he was surprised and said: "It is indeed a perfect foundation-building technique!? So that's how it is, it is necessary to perfect foundation-building. My previous practice was so wrong?"

The other two also widened their eyes and said quickly: "Ma Wenwu, give me the jade slip."

Ma Wenwu hesitated for a while and had to say that after getting the jade slip, he became greedy, but after thinking about it, he was greedy and could only hand over the jade slip. Sure enough, after reading the contents of the jade slip, the two of them were ecstatic and understood the shortcomings of the arsenal and knew how to make up for it.

Although it was difficult, at least there was hope. At this time, only Lin Yun and Yun Fan were still calm. Lin Yun looked at this scene with interest, while Yun Fan was a little surprised. He looked at Lin Yun and asked in a low voice: "Sir, there seems to be something wrong with the Medical Saint."

"Be careful, activate the realm bead and protect your mind." Lin Yun said.

Yun Fan was a little surprised, Realm Pearl? Could it be the thing given to him by the former Medical Saint, that he actually wanted to activate it to protect his mind? Sure enough, something was wrong.

Yun Fan was a little surprised at this time, but the doctor Saint said this, so he naturally did not dare to be careless and quickly activated the Realm Pearl to protect his mind.

At this time, a faint light appeared in the hall, as if there was a mysterious formation, surrounding the entire hall. Even, originally planned to check whether there were other secret Ma Wenwu and the other three in the hall, they seemed to be locked by invisible chains and could not move.

"What's this?"

"Oh no, it's a formation, I didn't notice it at all!" Ma Wenwu was a little shocked. At this time, he looked at the palace room again. This was where the formation was located, trapping them.

The true energy was completely suppressed. As for the physical body alone, it was impossible to break free from these invisible chains, and it was difficult to move for a while. Then, Ma Wenwu and others felt a headache. Suddenly, their faces changed drastically. At this time, they didn't even bother to speak, and quickly protected their minds.

Yun Fan also felt locked, and he also felt something crawling into his mind, but he soon encountered the power of the Realm Pearl and was bounced out. I don’t know what happened, but Yun Fan also knew to escape the catastrophe and immediately threw a grateful look at Lin Yun.

Lin Yun had nothing to do with it, and the invisible chains could not get close to him. As for the faint lights, he dared not get close to him.

"I am not under the control of the dark lock body array, and I can't even get close to you. Master Medical Saint, I still underestimate you." Yang Xi spoke at this time, completely different from his previous appearance, with a cold face and a huge difference in his aura.

Lin Yun didn't respond yet, but scared Ma Wenwu and the other two. What's going on?

Regarding the city lord who took the initiative to tell Lin Yun about the treasure, I just want to say that he did it on purpose.
