Yinfeng Sect had always been vicious, so it was naturally not a good thing for them to carry out an important mission in their sect.

Thinking of this, Xiao Yi couldn't help but look at Shangguan Leiting and asked, "Mr. Shangguan, I wonder, what other intentions does the Yinfeng Sect have besides the Haotian Stone Mine?"

At this moment, Shangguan Leiting slightly recovered from his shock. After listening to Xiao Yi's question, he looked confused and replied, "I don't know. I think the mine vein of Haotian Stone is the biggest secret of Smarty Mountain. I originally thought that the Yinfeng Sect must have come for the mine vein. I didn't expect that it had another purpose."

"In that case, we can only go out and take a closer look." Xiao Yi replied in a deep voice.

"Yes." At this moment, Shangguan Leiting was only obedient to Xiao Yi. After listening to Xiao Yi's words, he immediately agreed and stood up with his daughter's help. However, before he left, he said to Xiao Yi, "Mr. Xiao, thank you for saving us. I have nothing worthy enough to repay you. Please choose any treasure in this secret room. No words can express my gratitude for your great kindness."

Xiao Yi glanced at the treasures and some precious medicinal herbs. He also had enough. As for the refining materials, he had already taken out nine kinds of masculine things and refined a Nine-sun Net that was mainly used to restrain evil ghosts. As for the other things like luminous pearls, he did not care. Therefore, he shook his head and said, "I have no need for them for the time being. When I really need something to refine the weapons in the future, I will ask Mr. Shangguan for help."

"Mr. Xiao, if you need anything, just let me know. I'll give it to you immediately." Shangguan Leiting hurriedly said.

Xiao Yi didn't say anything else. He asked Shangguan Leiting to remove all the restrictions in the passageway, and the three of them walked out of the deep underground tunnel.

The moment they leaped out from behind the waterfall, the glaring sunlight felt as though they had been separated from the rest of his life.

Only when their feet were just standing on the ground, they suddenly felt three waves of fierce killing intent that rushed over from not too far away.

"Is there another strong enemy coming to attack us?" Xiao Yi, father and daughter were shocked at the same time.

However, a moment later, they discovered that the owners of the three murderous auras were all acquaintances. They were the three elders of Smarty Mountain, Ouyang Shi, Xia Yi, and Lu Xue.

The three people looked anxious, and their breath was disordered. They rushed to this side and happened to see Xiao Yi and the others jumping out from the waterfall.

"Sect Leader..." The three of them were all pleasantly surprised at the sight of Shangguan Leiting.

After being plotted by the Yinfeng Sect and Lei Fawkes, the three of them had internal strife. They left the Smarty Mountain one after another. When they fought fiercely, they got the news that the Smarty Mountain had been invaded by foreign enemies and their Sect Leader was missing.

The three realized that they had fallen into someone else's plot. They rushed back desperately, only to see the bodies lying all over the place with blood flowing like a river, and Sect Leader and his daughter went missing. They were regretful.

All of them rushed towards the biggest secret of Smarty Mountain, the entrance of the waterfall.

They hadn't expected to see Xiao Yi and the others appear.

This was also thanks to Xiao Yi's ability to turn the tide and kill the people from the Yinfeng Sect. Otherwise, everything would be finished when the three elders came to help.

"Sect Leader, have you recovered?"

"Sect Master, your arm..."

The three of them asked the same question almost simultaneously, their concern permeating their expressions and speech.

Shangguan Leiting quietly sighed. However, he simply told the three of them everything that had happened during these two days.

The three of them were stunned when they heard this. In the next moment, they simultaneously knelt on the ground in front of Xiao Yi. They were all thankful that Xiao Yi had saved their Chief and his daughter and was able to preserve this Smarty Mountain.

Xiao Yi quickly helped the three people to stand up. After suffering from this disaster, they felt sorry for each other when they saw each other again.

"Lei Fawkes normally looks so simple and honest. Who would've thought that he's actually a traitor? It is utterly devoid of conscience." Ouyang Shi said, gritting his teeth and stroking his wrist.

"That's right. What a shame that we didn't found out."

"Xia Yi, I'm sorry that I've balmed you. Due to my short-sightedness, the sect leader suffered such a great disaster that he lost an arm. I'm willing to accept his punishment." Ouyang Shi said in pain. He then knelt down on one knee in front of Shangguan Leiting.

Xia Yi and Lu Xue also copied Ouyang Shi's movement. They knelt down one after another and said loudly, "We are willing to receive the punishment of the Sect Leader."

Shangguan Leiting helped the three people up with his only arm. His face was full of vicissitudes of life. "Junior uncle master, Xia Yi, Lu Xue, this is the tribulation of my Smarty Mountain. As the saying goes, ordinary people are innocent, but they deserve the price of their treasures. The secrets of the Haotian Stone mine vein will one day be exposed to the world. Although my Smarty Mountain has been expanding in recent years, it's still weak. It's not enough to protect this mine vein at all."

Shangguan Leiting looked at Xiao Yi while speaking, but he sincerely said to Xiao Yi, "Mr. Xiao, Mr. Xiao is very experienced, and you are very blunt. I think that Mr. Xiao must have an extraordinary background. I want Mr. Xiao to pass a message to your sect. If you can ensure the safety of my Smarty Mountain, I am willing to work for your sect, and I am willing to give a certain share of the profits of the Haotian Stone mine. I don't know if Mr. Xiao can help?"

All the elders were surprised to hear Shangguan Leiting's words. They didn't expect that he would take the initiative to ask to be an underling of Xiao Yi's sect. However, after a while, they all understood Shangguan Leiting's decision. Smarty Mountain was weak. For so many years, it was all thanks to people's careful and conservative secrets that they could keep the Haotian Stone Mine vein. But now, as soon as the traitor appeared, the secret of the Haotian Stone Mine vein was no longer a secret.

Moreover, the Yinfeng Sect's methods were extremely cruel. If one day it fell into their hands, they would all die without a burial place. Not only would they not be able to keep the mine vein, but they would also lose their lives.

Instead of that, it would be better to find a sect that could depend on. And from Xiao Yi's performance, it could be seen that he cultivated the orthodox cultivation method. He valued friendship and loyalty, which showed that he was not a treacherous man. If they could really attach themselves to such a sect, it would be the best choice for Smarty Mountain.

Therefore, the three of them quickly thought, but they did not say anything. Instead, they looked nervously at Xiao Yi, waiting to see what Xiao Yi would say.

Hearing Shangguan Leiting's words, Xiao Yi smiled bitterly in his heart. If they knew that he was just an independent cultivator, he didn't know what they would think. However, Xiao Yi had been making plans for a long time recently. However, he always felt that it was not the right time, so he was not in a hurry.

However, when he heard Shangguan Leiting's direct request, Xiao Yi felt that it was the right time for him to do so.

Therefore, Xiao Yi did not make it clear. He thought for a moment, then nodded and said, "Mr. Shangguan, to tell you the truth, the sect I belong to is called the Dark Medical Sect, which is an orthodox sect of foreign cultivators. It follows Heaven's law and cures diseases, and saves lives. When it comes, it will follow the people's will. However, this matter is of great importance, so I have to go back and discuss it with the inside of the sect before making a decision."

Hearing Xiao Yi's words, Shangguan Leiting and others were all overjoyed. Although they had never heard of the Dark Medical Sect, Xiao Yi was so knowledgeable and profound in cultivation at such a young age. They knew that the Dark Medical Sect was bound to be extraordinary. Thinking about this matter, as long as Xiao Yi said it, the sect had no reason to disagree. This was a win-win situation. It was beneficial to both Smarty Mountain and the Dark Medical Sect.

After receiving Xiao Yi's assurance, Shangguan Leiting and the rest finally heaved a sigh of relief.

However, Xia Yi frowned slightly and said, "Sect Leader, Mr. Xiao, when we were looking for you, we found an unusual collapse not far from here in the valley. The collapse was huge, but there was no sign of life in it. Although I felt strange at that time, it was more important to look for you. Now that I think about it, I find it very strange."

"Oh? An unusual collapse? Where is it? Bring us over to take a look." Before Shangguan Leiting could say anything, Xiao Yi's heart immediately came to his mind, and he immediately said.

"Yes, Mr. Xiao!" Xia Yi responded in a hurry and took the lead to stride into the col not far away from here.

The valley was not far from the waterfall. After going around a cliff, they arrived at the valley.

However, as soon as they arrived, they were surprised to find that the original cliff had already collapsed, revealing a large area of an underground water source.

This was not rare for Smarty Mountain. It was initially a place where mountains and rivers connected, and the environment was excellent.

For some reason, a large and useless cliff had caved in, making it impossible for everyone to understand the reasoning behind it.

After thinking for a while, Xiao Yi waved his hand and set up a protective shield. Then he jumped into the underground water source.

Seeing Xiao Yi's action, Shangguan Leiting and others could not help looking at each other. As soon as Shangguan Leiting winked, Xia Yi immediately followed Xiao Yi and jumped in.

Usually, the water source was hidden behind the cliff, but it was very deep. When they jumped in, they found that it was more than 300 meters deep. Xia Yi followed Xiao Yi all the way and gradually went deep into the dark water, where one could not even see a finger in front of him.

However, both of them had very high cultivation and a powerful Divine Awareness. Even if there was no light source, they could still clearly feel everything in the water source.

However, Xia Yi felt that after Xiao Yi released his Divine Awareness to explore, he actually trembled and then dived into the water at a high speed, as if he had found something really frightening.

"Mr. Xiao, what on earth happened?" Xia Yi called and asked worriedly.

However, Xiao Yi did not answer him. He dived all the way quickly and finally reached the bottom of the underground water source a few minutes later.

Although Xia Yi had a protective shield, the huge water pressure under the water still made it difficult for him to breathe. He tried his best to run his True Energy so that it was not so hard for him to catch up with Xiao Yi.

However, he felt that Xiao Yi was quietly standing in front of a huge hole, looking at it carefully with a gloomy face.

"Mr. Xiao, what's wrong?" Xia Yi looked at the huge hole in the bottom. He only felt that there was a constant gloomy smell coming out of it. It seemed to be unfathomable and he didn't know where it led to.

"Let's go up first. It's even more troublesome than I thought." Xiao Yi's voice was serious and his eyebrows were tightly knitted together.
