The master and apprentice left the cloud wolf iron cavalry camp, and when they were far away from the military camp, Tong Lao regained his original appearance. He told him that the longer this state lasted, the more damage it would do to his body. Because this is a method of forcibly restoring strength, it is different from the ordinary Yirong pill.

Luo Tian was very worried when he heard this, because after he found out that after his master had restored his true face, he had become much older. It seems that this elixir is really not eaten indiscriminately.

Seeing Tong Lao's face become even older in order to save himself, Luo Tian was very distressed. In addition to his parents, it is also the master who is good to himself. Tong Lao is now second only to his parents in Luo Tian's heart. He didn't want to see Tong Lao get hurt in any way because of himself.

"Cough" As soon as the old boy recovered, he coughed weakly. Luo Tian hurriedly went up to help him. Tong Lao has always been in good health, and he has never seen Tong Lao so weak in the past few years.

"Master, are you alright? Luo Tian asked with concern, he knew that even if Tong Lao had something, he would not say it. For Luo Tian, Tong Lao only had selfless dedication, but he never said what he asked Luo Tian to do. Of course, at the beginning, he said that he would let Luo Tian help him complete one thing, but until now, Tong Lao has not said what it is.

Because Tong Lao was unwell, everyone sat on Bo Zai's body. Today's Bo Tsai is bigger, and it's no problem to sit three or five people at the same time. Even Yu'er was standing on Bo Zai and jumping around.

"Eh, Yu'er, don't jump around, it's Bo Zai down there. Luo Tianquan said.

Yu'er finally recovered after this time, but the naughty Yu'er returned. Luo Tian was ashamed to face Yu'er, but she was like no one. This made Luo Tian feel even more guilty. At that time, he actually doubted Yu'er's character. Therefore, Luo Tian has never dared to talk to Yu'er.

"Hehe, I can finally play happily again. I won't jump hard, Bo Zai, you don't hurt, right?" Yu'er said as she jumped. It seems that Yu'er is still the same as before, and there is no estrangement between Yu'er.

"That, Yu'er, I want to apologize to you, I shouldn't have doubted you last time!" Luo Tian mustered up the courage to apologize to Yu'er. If she didn't apologize, Luo Tian always felt shameless to face her.

"Ahh Oh, you said that you were injured, it doesn't matter, you can't beat the black mist, you won't be able to save me!" Yu'er said and was still jumping around!

"Ahem, it's not. It's my suspicion that you will tell the whereabouts of Master," Luo Tian said with his head lowered and felt guilty.

Hearing his words, Yu'er also stopped. I saw her turn around and suddenly knocked Luo Tian off Bo Zai's back with her antlers, which surprised Tong Lao and Bo Zai.

"Haha, okay, report for back. Let's settle the score, and don't doubt my character anymore!" Yu'er said with a laugh.

Luo Tian got up from the ground, not only was he not angry, but he also laughed. It seems that this is the real friend. There's nothing that separates real friends. Especially Yu'er, a spirit beast with a pure heart, it is impossible to remember the hatred of friends. Moreover, the situation was extremely urgent at that time, and Luo Tian was too worried.

Luo Tian and Yu'er were talking and laughing on Bo Zai's back, while Tong Lao was meditating with his eyes closed. Luo Tian had already made up his mind that from now on, whether it was for Master, or Yu'er and Bo Zai, he would no longer have any doubts. They are the most trusted people in Luo Tian now!

Because Bo Tsai can't fly in the air for a long time, he lands down and walks in the forest for a while every time he flies. When we arrived two hundred miles away from Gushan Town, it was getting dark.

"Master, what are you bringing me to this barren mountain for?" Luo Tian was very puzzled, he had traveled for a day to see this barren mountain?

"Hehe, this is the fief given to you by the Lord of the Dust Cloud Country! From today onwards, everything here belongs to you!" Tong Lao said happily, and then he took out a picture. There seems to be something marked on the picture.

"Huh, Master, what is this map for?" Luo Tian was deeply puzzled.

"That's the reason for coming here this time, there is an underground ore vein within a radius of one hundred and ten miles!" Tong Lao smiled and looked at the ground map.

Luo Tian was very surprised when he heard this, what the master said should be the legendary Yuanshi vein! There is actually a Yuanshi vein in this barren mountain! This is simply a pie falling from the sky.

Yuanshi veins, like spiritual springs, are spiritual creatures born from heaven and earth. The spiritual spring is a liquid spiritual object, and the veins of the yuan stone are solid! Moreover, this yuan stone is the circulating "currency" of the immortal cultivation world.

The Yuan Stone is a stone that is full of vitality and can be directly absorbed by monks. It took an unknown number of years for a vein to be born. If the spiritual spring is endless, then this yuan stone vein is a one-time one. Once it is mined, it can no longer be produced.

"Huh, Master, I feel it, I can't be wrong!" Luo Tian suddenly exclaimed. He didn't know if this kind of perception was an ability before, but now he can be sure. Luo Tian knew that he had the ability to perceive spiritual things, so he told Tong Lao about this ability of his own.

"What? You actually have such ability! Why didn't you sue Sù as a teacher before?" Tong Lao was also surprised.

"I used to think that it was just my instincts that were sharper, but now I can clearly feel the vitality emanating from the veins. That's why I just felt that this is an ability!" Luo Tian explained.

"Oh, in this way, you should have been able to collect more medicinal herbs in the first place. As a guess for the teacher, this ability may become stronger as your realm improves. It seems that the apprentice is really talented, and I am really happy for you. Tong Lao said with a smile. How much else did Luo Tian surprise him, even Tong Lao himself was curious.

From the very beginning of wanting to accept Luo Tian as an apprentice, Tong Lao felt that this was fate in the dark. Later, Luo Tian sensed many rivers of vitality, and then to his magical perception ability. This qiē shows that Luo Tian himself is a man full of opportunities.

Tong Lao felt that his apprentice was destined to embark on the path of cultivating immortals, which was not something that Luo Tian's parents could control. Maybe if he hadn't taken Luo Tian as a disciple, there would have been others who would have guided Luo Tian on this path. This should be Luo Tian's fate. What will happen after all, you can't stop it!

Luo Tian's ability is very magical, even Tong Lao can't sense the specific location of the ore vein, but Luo can sense it. And it seems to be an innate ability! This can't help but make Tong Lao curious about Luo Tian's life experience.

In the world of cultivating immortals, legend has it that there are some monks who failed to cross the tribulation, and under the powerful heavenly tribulation, they were able to save a trace of their soul from being destroyed, and that soul entered the netherworld ghost world, and then could be reincarnated as a human being. Could it be that this disciple of his own in his previous life turned out to be such a powerful figure? Tong Lao was also not sure.

Luo Tian's perceptual ability will also have a sense of ordinary medicinal materials. As everyone knows, this ordinary herb can also be said to be the lowest "spirit grass". It's just that their spirituality is negligible. It has no effect on immortal cultivators, but it has the effect of healing diseases and injuries for mortals.

There is also a class of medicinal herbs, such as ginseng, reishi and the like. If it has just grown, it can only be regarded as an ordinary herb. But after hundreds of years, or even thousands of years of gestation, it has become a real spirit grass. Therefore, there is no too limited standard for this spiritual object. It still depends on the environment and the time of growth.

After such speculation, Luo Tian will have a sense of spiritual things, and even some masters can't do it. Tong Lao speculated that Luo Tian should not be the reincarnation of a monk, but he could not explain the source of Luo Tian's ability.

"Master, I'll take you to the location of the ore vein!" After Luo Tian finished speaking, he took Tong Lao to find the location of the ore vein!

Along the way, Tong Lao also inquired in detail about the range, strength and other information of Luo Tianna's sensing ability. Because he wanted to find out the source of this power for his disciples. But Tong Lao didn't think about what the reason was when he wanted to break his head.

Luo Tian took Tong Lao to a hill twenty miles away. This hill could not seem more ordinary. However, Luo Tian could feel the flow of the slightest breath. It's like a river of vitality, but it's just a faint breath.

"Is it here?" asked Tong Lao.

Luo Tian nodded, indicating that he sensed that it was around here. And there's only one hill nearby. If Luo Tian couldn't sense it, he really couldn't see any difference here.

When Tong Lao heard this, he flew directly into the air. I saw him run his true qi, and then made a mark with both hands. Hearing a loud "boom", Tong Lao's punch blasted a big hole in the hill! Then Tong Lao continued to throw several punches, and the hole became deeper and deeper. It wasn't until he reached the center of the hill that Tong Lao stopped, and then came to Luo Tian's side.

"Let's go, so that you can go to the inside of the mountain, most of the spirit stones are in the center of the mountain, and they are not so light and can be shattered. As he spoke, the old man walked towards the big hole. Luo Tian and Yu'er sat on Bo Zai and flew over closely following Tong Lao!

This big cave is about five feet high, and everyone stands at the entrance of the cave and looks inside, and the cave is dark. When the old boy came to the entrance of the cave, he walked directly into the cave. This cave was just punched out by him, so there shouldn't be any danger inside!

Luo Tian and the others then entered the cave as well. Just now, they only felt the water vapor rushing from their faces at the entrance of the cave, and the deeper they went inside, the heavier the humidity felt here. Could it be that there is still a water source inside this mountain?

When everyone came to the end, something surprising happened! In the interior of the mountain, there was an underground river flowing! And on the surrounding rock walls, you could see stones that shimmered with a pale blue light!

"That's right, it's really a water-attribute Yuan Stone!" said Tong Lao with a smile!

"Is this Yuan Stone also divided into attributes?" Luo Tian asked.

From Tong Lao's mouth, I know that this yuan stone is also divided into many types. The most common ones are the Water Spirit Stone and the Fire Spirit Stone! These spirit stones have different properties due to long-term immersion due to different environments. For example, the interior of this mountain is a water element environment, so this must be a water element stone.

Fire spirit stones are usually born in volcanic areas, or in environments where the fire element is strong. In addition, the three elements of gold, wood and earth, the original stone, is also the same reason.

Just when Tong Lao and Luo Tian happily wanted to dig the Yuan Stone, the river in the mountain actually began to roar! Tong Lao didn't have time to say more, he directly pulled up Luo Tian and flew towards the entrance of the cave!
