Walking further, he saw hordes of demon beasts, and even demon cultivators who had transformed into shapes.

Qin Di was too lazy to do anything, so he simply pasted a demon talisman on him and Yan Xue. After pasting the demon talisman, they began to exude demonic energy, making the little fox stare at them in amazement.

They walked along the river, and wherever they passed, the demon beasts avoided one after another, and the shape-shifting demon cultivators bowed to them.

The terrain got lower and lower, and gradually came to a depression, where several rivers gathered, and there was a large lake, and in the middle of the large lake there was a piece of land.

Qin Di and Yan Xue jumped over to the land, looking up and seeing that there were high mountains all around, and there were some strange runes on the cliffs. Qin Di only glanced at it and knew that it was an earth-based immortal text.

He realized that this should be the place where some great immortal set up an altar. Although the altar has been demolished, the runes are still working, so the land continues to produce red treasure soil.

Qin Di looked down at the soil and found that the soil on the surface was only a fourth- or fifth-order spiritual soil, and the grade was not very high.

He said to Yan Xue: "You are guarding on the side, and I will sink into the soil to take a look." ”

Then he cast the earth escape trick and disappeared into the earth.

Qin Di is a concurrent cultivation of the five elements, and Tu Dun Kung Fu is the basic method of Tu monks, but there are restrictions on how ordinary people can perform this exercise, and they can't go too deep into the soil, and they can't stay too long in one breath.

Qin Di sank into 30 zhang in one go, and while sinking, he observed the surrounding soil. He noticed that the further down he went, the higher the grade of the soil, so he continued to drill down.

However, to his surprise, even though he went 60 zhang underground, he had not yet reached the bottom, and he had never touched the rocks, and this place was like a bottomless pit.

At a depth of sixty zhang underground, a third-order treasure soil has already appeared.

Qin Di continued to sink, thinking, "I don't believe it, I can't see the bottom yet!"

When he sank into the ground, he found that he was surrounded by fifth-order treasure soil. At this time, the pressure around me is getting heavier and heavier, and if I change someone, I am afraid that I will be overwhelmed.

Qin Di continued to go down, until it was 180 zhang deep, and finally encountered an obstacle, and there was a mountain rock below.

At this time, he found that the surrounding soil had turned into a ninth-order treasure soil, almost immortal soil. Such a treasure is very precious, and it is a very rare good thing in the world of tea.

Qin Di took out the Naxu gourd and directly collected the underground treasure soil, he started to collect it from the lowest layer of the ninth-order treasure soil, and went all the way up to the first-order treasure soil, and finally left a huge space underground.

At the bottom of this space, there is also an altar! It turned out to be a double-decker altar, the part above ground has been destroyed by people, and there is an altar 180 zhang underground. It's a pity that the altar on the ground was destroyed too early, otherwise you should be able to see the fairy earth. In the future, when the great immortal who set up the altar returns, he may be so angry that he vomits blood.

However, since it is a carefully set up altar, there should be a protective circle, and I don't know what the fault is, the circle is gone.

Qin Di came out of the soil, and it didn't take long for the space to collapse, forming a deep crater, and the lake water poured into it, causing the water level in the lake to drop, exposing some places that were originally covered by water.

At this time, Yan Xue was looking for the dog's head gold by the lake.

In fact, the real dog's head gold is rare, buried in a large amount of soil, and the treasure soil collected by Qin Di is also mixed with some fragments of spiritual gold, so he said to Yan Xue: "Let's go, let's go back, if necessary in the future, we can come back again." When I have cultivated to become a spirit immortal, I will go back and refine all the phoenix blood gold in these mountains, and then use it to refine immortal weapons. ”

Yan Xue asked, "Sir, have you found the altar?"

Qin Di nodded: "I found it, along with the treasure soil, I have included it in the void gourd, I will take a closer look to see if there are any marks left by the immortals on the altar." ”

"Sir, if you take away the altar, will anyone come to you?"

"Just erase the mark, and you'll be fine. ”

The two of them returned to Dayong City, and then threw the little fox into a demon cultivation cave, and let her stay with the tiger Du Zhong.

Qin Di poured a large amount of treasure soil into the Lingxian Cave Heaven, first picked out the red blood gold visible to the naked eye, and then poured the treasure soil into the homemade altar in batches, and after grinding, it flowed into the pool.

He tripled the size of the pool, added more earth-based immortal texts to the pool wall, threw more broken cave heavens into it, and waited for the spirit veins to climb out of the cave sky, automatically enter the pool, and slowly increase the level of the treasure soil. It was a slow process, and according to his estimates, it would take about a thousand years before he could obtain the immortal soil.

Afterwards, he took out the altar left by the Gu Immortals, examined each piece of green jade one by one, and searched for a long time before finding the mark left by the Gu Immortals, on which the words "Great Wilderness" were written!

Qin Di was stunned: "I didn't expect this old guy to be again! How come I can touch the mark he left wherever I go? He is actually very familiar with the earth and the earth tea world, can it be said that he is a native immortal? Shouldn't it! Generally speaking, rabbits don't eat the grass next to the nest, but all native immortals generally don't destroy the plane they grew up in, this old guy doesn't know what's going on!"

Qin Di thought about it carefully, and felt that since the Great Wilderness Immortal Venerable had been to the Earth Tea Realm, he should have left relevant legends, so he went to the Royal Library to rummage through the records. He searched for a long time but couldn't find it, so he asked the manager of the library.

The pavilion master is a ninth-order monk named "Hazel Leaf Monk", who is at least sixty years old in appearance, and his real age is about sixty thousand years old. His realm is a little higher than that of the withered leaf master, so he is also the inner gate elder of the Immortal Leaf Sect.

The Hazel Leaf Lay didn't know Qin Di, nor did he know that he was an alchemy immortal master who was important in the sect. Because he was older, he didn't participate in the Convergence Conference held in the Great Yin Kingdom, nor did he go to the Xunhuang Holy Relic Mountain. However, he sat on the top floor of the library pavilion, swept his senses, and saw the "Shangqing" waist card worn by Qin Di, so he appeared and wanted to chat with Qin Di.

"Little brother's surname?"

"My surname is Qin, and my single name is a flute character, how do you call my seniors?"

"I'm Hazel Leaf, the inner door elder in charge of the library pavilion, I just heard you ask about the 'Great Wilderness Immortal Venerable', I have vaguely heard of this person, his strength is very strong, 1.5 million years ago, he suddenly appeared in Kuntu City within the threshold, shot and killed the city lord of Kuntu City, and he was the city lord for less than 3,000 years, and then disappeared again. ”

"It's actually within the threshold, how do the elders know?"

"This is a great event that happened many years ago, and it is recorded in ancient books. ”

"Does the Great Wilderness Immortal Venerable have any apprentices left?"

"3,000 years is too short a time to train disciples. However, he left a stone tablet in the City Lord's Mansion in Kuntu City, saying that he would come back in the future. ”
