Ye Tian has been observing the environment inside since he entered the ruins, obviously the entrance to the entrance is in a deep underground cave, but after coming in, he is in a mountain forest. Although the sky is different from the outside world, there is no scorching sun shining in the sky, but the sky is very bright, and some colorful lights are cruising in the air, which should be the defense and prohibition of the entire space, illuminating the whole space as if it were daylight outside.

Ye Tian judged that the ruins should be an independent space, somewhat similar to his Wuji world, entering and exiting need to go through special methods, and I don't know what kind of powerful person created it, such a great supernatural power is unimaginable to ordinary people.

After advancing for about half an hour, Ye Tian killed a total of three demon beasts, each demon beast was at least a cultivator in the late stage of quenching, the demon beasts all had spiritual sense, and the rest of the small demon beasts felt that the aura released by Ye Tian was powerful, so they avoided it early and avoided it early, and generally did not take the initiative to attack Ye Tian.

Further on, the woods reached the edge, and in front of them was a cliff wall more than 100 meters high, the angle was almost vertical, and there was no way forward.

Ye Tianzheng was puzzled, Xiao Bai on his shoulder pointed diagonally forward with his paws, Ye Tian looked in the direction it was pointing to, and saw that the cliff in front of him was full of vines.

Ye Tian approached cautiously, did not find any danger, under the guidance of Xiao Bai, with the sword in his hand to open a place where vines are dense, a stone wall was exposed, the stone wall was very rough, it looked no different from the surrounding mountain wall, but Ye Tian carefully distinguished, but found that this place was originally a camouflaged stone door.

The stone door was closed so tightly that there was no handle to pull on, and it was so tightly connected to the surrounding stone wall that it was impossible to pry open it with a weapon.

"How do you open this?" Ye Tian searched around to see if he could find the mechanism that opened the stone door.

A quarter of an hour later, Ye Tian returned to the position of the stone gate with his head down, looking at the stone gate that was still the same.

In desperation, Ye Tian was ready to violently demolish it, he took out the mine hoe from the Wuji World that day to dig the spirit stone, and chiseled it violently at the stone gate.

Sure enough, no matter how sophisticated the mechanism was, it couldn't stop the violent demolition, and after half an hour, the stone door was finally full of cracks, and it shattered into several pieces with a bang.

Ye Tian was overjoyed, and hurriedly dug down the broken stones with a mine hoe, but when he saw what was inside, he was immediately dumbfounded.

It turned out that the stone gate was just a camouflage, and the vajra black iron inside was its main body. Looking at the vajra black iron that he didn't know how thick, Ye Tianzhen had an urge to hit the wall. After making such a lot of effort, only the outermost layer of stone shell was removed, and then he wanted to violently destroy the Vajra Xuantie inside, unless Ye Tian was promoted to the innate level, it might still be possible to hold a Xuan-level weapon in his hand. With Ye Tian's current strength and the mine hoe in his hand, if he wants to enter violently, he doesn't have to think about it.

"Xiaobai, how do you say we can open this door?" Ye Tian had no choice but to ask Xiaobai.

Xiao Bai's big eyes blinked, and his little paws pointed at the dark iron gate, and he couldn't seem to find the mechanism of the iron gate.

Ye Tian didn't think about starting from the stone wall next to the Xuantie Gate, but when he dug for a long time before digging a fist-sized stone pit, he no longer had the confidence to continue digging. Think about it, it's so easy to dig up, why do people still make the dark iron door?

Scratching his head, scratching his head again, Ye Tian couldn't wait to draw a circle on his head, and he didn't come up with a way to open the Xuantie door.

"Could it be that it took so long and consumed so much strength that it was impossible to come here for nothing? Isn't this entering Baoshan and returning empty-handed?"

It took another half an hour, but Ye Tian still didn't get anything, so he had no choice but to give up.

"Where should I go now?" Ye Tian thought about it for a moment, if he retreated back into the forest, he would probably meet Wu Zheng and them, if those people rushed up, he would definitely not be an opponent. If you encounter disciples from other sects, it is not a good thing, you are likely to be besieged by them, and you can only flee when the time comes.

After thinking about it, Ye Tian decided to use the vines to climb the cliff wall and see what was on it, it was really not good, it was not too late to come down, the top of the cliff was more than 100 meters high, and it was good to stand on it and look at the environment in the distance.

Ye Tian's current cultivation is not difficult to drag the hundred-year-old vine to climb the cliff, and it only took a dozen breaths for Ye Tian to stand on the top of the cliff.

As soon as he went up to the top of the cliff, Ye Tian's nose was almost crooked, the mountain stone on the top of the cliff seemed to have changed, there was a crack that was more than one person wide and more than three meters long, Ye Tian lay on the crack and looked inward, the crack led to the depths of the mountain belly under his feet, and down the crack, it was the stone chamber cave behind the Xuantie Gate.

Ye Tian spent so much time and effort below, but he couldn't open the Xuantie Gate, who knew that as long as he followed this crack, he could easily go down, such a dramatic turn made Ye Tian want to scold his mother.

The cracks are very irregular, and the stone stubble on both sides is a little sharp, as if it has just cracked for a long time, and it is very easy to climb.

From the outside, he thought that this was just a stone chamber dug by man, but when he entered the inside, Ye Tian realized that this was a huge natural cave, which was at least the size of a football field.

"Mili!"

Just as Ye Tian was still observing the environment in the cave, Xiao Bai let out an excited cry. Ye Tian looked in the direction of its little paws, and couldn't help but be stunned.

In the depths of the cavern, a thick and large stalactite pillar plunged straight down from the roof of the cave and stabbed a spear vertically into the ground. The tip of the spear is only about one meter from the ground, and below the tip of the spear is a half-meter-high stone platform, above which is placed a jade tripod, which emits a faint white light, which looks very mysterious in the dark cave.

Ye Tian did not rush forward to check, but carefully looked at the surrounding environment, for fear that some powerful demon beast was hiding on the side and suddenly launched an attack on him.

Under observation, Ye Tian did not find any traces of the activities of demon beasts, not even flying animals such as bats, judging from the environment in the cave, the crack on the top of the cliff should have just appeared for a few days, and the cave has been closed, so it can be so safe here.

With this discovery, Ye Tian was also a little relieved, exploring the ancient ruins was a dangerous move to die for a lifetime, and if he was not careful, he would die, and any carelessness could cause him to lose his life in an instant.

"It's ...... Earth Vein Spirit Milk?" Ye Tian looked at the milky white liquid in the jade ding, and his heart was also excited. There are six drops of leyline spiritual milk, which means that no one has been here for 600 years.

Earth vein spiritual milk, a small spiritual vein, a hundred years to generate a drop, it has no attributes, no matter what kind of attribute martial arts can be taken and refined, it is a priceless, priceless treasure of heaven and earth.

"It's gone, with these six drops of Earth Vein Spirit Milk, there is no problem with my Earth Pupil Technique cultivation to the Xiaocheng realm. Not only that, but one's own cultivation can also be improved to a certain extent. Just by getting these six drops of leyline spiritual milk, this exploration of the ruins will not come in vain!"

Ye Tian was proud and did not get carried away, and hurriedly took out a jade bottle and filled the earth vein spirit milk in the jade tripod. After thinking about it, he put the jade tripod back in its original position. Although this jade tripod is also a priceless treasure, the leyline spirit milk has been stored in it for six hundred years and has not volatilized, but Ye Tian still understands the truth of drying up and fishing, once there is no treasure like the jade tripod to contain the earth's leyline spirit milk, the earth's leyline spirit milk here will volatilize clean, and it will be difficult to collect it again.

"Forget it, it's better to do less things that harm others and don't benefit yourself, there is something to gain, and the leyline spiritual milk here will be left to the people who are destined to do it later. Ye Tian reluctantly looked at the jade tripod and shifted his attention to the stalactites above the jade tripod.

According to the position of the jade tripod, the leyline spiritual milk should flow down along the stalactites above, and there must be a place above the stalactites that flow out of the leyline spiritual milk. After getting the leyline spirit milk last time, Ye Tian also checked a lot of information about the leyline spirit milk when he went back, and knew some of its production mechanisms.

According to the size of the spiritual veins, the spiritual veins are divided into five levels, from low to high, they are miniature spiritual veins, small spiritual veins, medium spiritual veins, large spiritual veins, and giant spiritual veins. The four major forces of the Nanyue Mountain Range occupy all small spiritual veins.

The area covered by the miniature spiritual veins was very small, and the concentration of gathering heaven and earth spiritual qi was not high, only twice that of ordinary areas. Only lower-grade spirit stones can be produced in the spirit veins, and there are not many of them. As for the leyline spirit milk, the miniature spirit vein can only produce one drop every thousand years.

The area covered by the small spiritual veins is more than twice that of the miniature spiritual veins, and the concentration of the spiritual energy of the gathering heaven and earth is four times that of ordinary areas.

Medium-sized spirit veins are stronger than small spirit veins, not only covering a larger area, the concentration of gathering heaven and earth spiritual energy is eight times that of ordinary areas, but also producing much more medium-grade spirit stones than small spirit veins, and occasionally producing a small number of high-grade spirit stones, which can generate a drop of earth vein spirit milk every ten years.

Large spiritual veins, both in terms of coverage and the concentration of gathered spiritual energy, far exceed medium-sized spiritual veins. There are also more high-grade spirit stones produced than medium-sized spirit stones, and traces of top-grade spirit stones can occasionally be seen, and a drop of earth vein spirit milk can be generated every year.

As for the characteristics of the giant spirit vein, there is no record in the general books at all, and there is no one in the entire Nanban Prefecture, it only appears in legends.

No matter what level of spiritual veins they are, they are the focus of contention among the major forces, and every new spiritual vein that is discovered will cause a bloody storm.

Since the leyline spiritual milk is dripping from the stalactite, it is likely that there is a channel on the stalactite to transport the spiritual milk. Ye Tian was now looking up at the top of the cave and looking closely, trying to find out the location of the passage that transported the leyline spirit milk. There should be a lot of spirit stones gathered there, especially some high-quality mid-grade spirit stones, which are likely to appear near the passage where the leyline spirit milk is transported.
