Ye Tian thought of a way to open the small metal door, and began to use his sword to chop the rock next to the metal door, and under the sword infused with the innate true qi of the wood system, the rocks around the metal door soon fell off one after another.

As a result, when Ye Tian saw it, he was immediately dumbfounded, after the rock next to the metal door was peeled off, he found that it was not installed on the rock at all, it turned out to be the portal of a metal house.

Until Ye Tian completely dug up the rocks around the metal house, a lonely metal house was exposed in front of Ye Tian, the four sides of the metal house and the roof were tightly sealed, only the foundation of the house was deeply embedded in the rock underground. Ye Tian dug deep all the way down, but he didn't see the end of the foundation of the house, and in desperation, he finally gave up digging and returned to the front of the metal door.

At this time, the shadow demon on Ye Tian's back reminded him that the groove on the metal door should be the key to opening this door.

Ye Tian carefully observed the shape of the groove, and didn't know what such a large circular groove was for, it was similar to the size of a basketball, and what had to be put in to activate it.

Generally, if you want to open a portal or something like that, you either have a special key, or you need special energy, but this groove is so big, who would make a special key look like this, and because the groove is much larger than the spirit stone, it will not need the energy crystallization like the spirit stone.

Suddenly, a flash of inspiration flashed in Ye Tian's mind, and the shape of this groove reminded him of an energy crystal, the Demon Crystal.

Different from the square spirit stone, the demon crystal is round, exactly the same as the shape of the groove on the metal door, and the size of the demon crystal is not fixed like the spirit stone, and the size of the demon crystal is also inconsistent for different demon beasts. In addition, this metal door appeared at the bottom of the pool guarded by the strange Jiao, so Ye Tian thought of using the demon crystal of the strange Jiao to try if he could open this metal door.

Ye Tianzheng wanted to take out the body of the strange Jiao from the Wuji World, so that he could take out the demon crystal for experimentation, and suddenly found that the man and the woman had not left yet, and were staying not far away looking at him, and he didn't know what he was thinking.

"Get out of here, or I'm going to do it to you." Ye Tian ordered the two to be evicted. Although some people already knew that Ye Tian was carrying a space magic weapon, Ye Tian still didn't want to use the Wuji World in front of other people, the fewer people who knew about this matter, the better, and the more people who knew, the more trouble it would bring to Ye Tian.

Originally, seeing that Ye Tian was very talkative, although his strength was strong, he didn't seem to like killing, Yang Pan and the others also wanted to see what kind of treasure was in the metal door, but they were driven away by Ye Tian's words, and they had to leave first.

They knew that the people who could come to the third floor of the Ten Thousand Clans Tower were not ordinary characters, and if they really disobeyed Ye Tian's intentions, they were likely to cause death.

Seeing the two leave, Ye Tian ordered the Shadow Demon to go above to stand guard, so as not to be spied on, or someone else to come and make trouble. The divine consciousness was suppressed too much at the bottom of the pool, and Ye Tian also had to be more careful to prevent being attacked by someone.

Everything was ready, Ye Tian took out the body of the strange Jiao from the Wuji World, the sword pierced a gap in the skull of the strange Jiao, and took out a round demon crystal from the skull, the size was similar to a basketball, which couldn't help but make Ye Tian overjoyed, his guess was likely to be correct, this demon crystal should be the key to opening the metal door.

Putting away the corpse, Ye Tian pressed the basketball-sized demon crystal into the groove on the metal door, and with a rumbling sound of metal shaking, the metal door in front of Ye Tian sank, and the door of the metal house opened.

The lake was blocked by an invisible diaphragm outside the metal house, and the scene inside the house was not clear, Ye Tian stepped in one step, wanting to see what was inside the house.

As soon as he entered the metal house, Ye Tian's eyes lit up, the house was very dry, and the lake water was completely blocked from the outside. The space is not as small as it looks from the outside, and it is the size of a basketball court.

In the middle of the room, there was a formation, a teleportation array.

Ye Tian walked to the teleportation array, looked at the introduction on a piece of the array disk, and finally knew the function of this teleportation array.

It turned out that this teleportation array was the passage to the fourth layer of the Ten Thousand Clans Tower, and this passage was actually opened by Ye Tian.

As a trialist who opened the passage of the fourth layer, Ye Tian could ride this teleportation array to the fourth layer of the Ten Thousand Clans Tower for free and obtain 100,000 points.

The latecomers were not so lucky, and they needed to spend 100,000 points to ride this teleportation array.

If you want to reach the higher level of the Ten Thousand Clans Tower, it is definitely not that easy, not only can you find the teleportation array hidden in the deep pool of the lake, but you also need to spend 100,000 points to use it, you can't do it without a certain amount of strength and luck.

Especially if you want to open this teleportation channel, you must kill the monster Jiao of the Renyuan realm, and then use its demon crystal to open the metal door that seals the teleportation array, which is many times more difficult than obtaining 100,000 points, and it is simply an impossible task for ordinary innate realm cultivators.

Ye Tian returned to the outside of the house and called down the shadow demon who was on guard above, wanting to take the shadow demon to the fourth floor of the Ten Thousand Clans Tower.

However, when Ye Tian wanted to retrieve the strange Jiao demon crystal embedded in the groove of the metal door, he was almost not vomited blood, the metal door sank into the depths of the earth and disappeared, and the strange Jiao demon crystal embedded in the groove was also taken away by it and could not be recovered!

"I'll go, my demon crystal, the demon crystal of the monster Jiao of the Human Yuan Realm, how much is it worth!"

It's a big loss!

It was useless to regret it, Ye Tian had no choice but to kick the metal house with his feet, except for feeling some pain in his feet, he didn't get any money back, so he had to take the shadow demon into the metal house and stand on the teleportation array.

Swish!

The information on the teleportation array disk changed: "The trialist who opens the teleportation channel is free, and the other person needs 100,000 points." ”

"I'll go, I'll fight with you!"

Ye Tian scolded the Ten Thousand Clans Tower for having no humanity, and took away his own monster demon crystal, not to mention, even his own demon servants had to charge a teleportation fee, which was even darker than the blackest profiteer.

Of course, in order to give face to the tower spirit of the Ten Thousand Tribes Tower, these words were all said by Ye Tian in his heart, and he would not offend the tower spirit of the Ten Thousand Tribes Tower for the sake of happiness. That's a wise guy, if he finds out that Ye Tian scolds him, he will definitely give Ye Tian small shoes to wear, in that way, Ye Tian's life in the Ten Thousand Clans Tower will not be easy in the future.

In desperation, Ye Tian had no choice but to press the teleportation tokens of himself and the Shadow Demon into the groove on the array disk, and the points of the Shadow Demon were deducted to zero, while Ye Tian's points increased by more than 50,000.

The Shadow Demon originally had more than 50,000 points, plus the more than 40,000 points deducted from Ye Tian, which was exactly 100,000 points less, which was the teleportation fee for the Shadow Demon to reach the fourth layer of the Ten Thousand Clans Tower.

And Ye Tian was supposed to get a reward of 100,000 points, but more than 40,000 points were allocated to Shadow Demon, so he only got a reward of more than 50,000 points.

Ye Tian and Shadow Demon together, it is equal to one point is not too much, and one point is not less.

With a familiar feeling of dizziness, Ye Tian knew that the teleportation array had been activated.

By the time they felt grounded, Ye Tian and Shadow Demon had already appeared under a brand new sky.

This is an island in the middle of a lake.

The area of the lake was endless, and it was somewhat similar to the lake on the third layer of the Ten Thousand Races Tower, and Ye Tian even wondered if the terrain of the fourth layer of the Ten Thousand Races Tower was exactly the same as the third layer.

This time, Ye Tian did not enter the lake to explore again, because he found that his divine sense had been able to detect the bottom of the lake, this lake was not the same as that of the third layer of the Ten Thousand Clans Tower, and the lake water did not suppress the divine consciousness, which meant that it was unlikely that there were secrets hidden in the lake.

Thinking about it, just being teleported to the fourth layer and giving you a place where secrets are hidden, the Tower of Ten Thousand Clans doesn't seem to be so kind. Secrets require strength and luck, and benefits do not fall from the sky.

Tissot!

Ye Tian still let the shadow demon control it, and he sat in the shuttle tail with his divine consciousness fully open, probing the surrounding environment, especially the flow of underground aura, looking for opportunities.

However, Ye Tian thought about the fourth layer of the Ten Thousand Clans Tower too simply, and before the Escape Heaven Shuttle flew out of the lake, he encountered a digital attack from the lake, and twice it was launched against them by the creatures of the Human Yuan Realm, if it weren't for the speed of the Heaven Escape Shuttle being too fast, plus the attackers were not prepared, Ye Tian and the Shadow Demon would be in trouble.

"Master, it can't go on like this, it seems that there are a lot of natives in the fourth layer of the Ten Thousand Clans Tower, if we are still as unscrupulous as we were in the lower layers, it is estimated that we will continue to be attacked by those powerful natives. Once you encounter the flying race of the Human Yuan Realm, it will be really troublesome. ”

The Shadow Demon reminded Ye Tian that as Ye Tian's demon servant, his life had been completely linked to Ye Tian, and once Ye Tian had three long and two short, the Shadow Demon would not have any good fruit to eat.

"Well, I've noticed these problems as well, but we have to get out of this lake as soon as possible, and we can only take some risks for the time being. Once out of the waters, we would have marched on foot, which would have been safer than flying in the air. ”

Ye Tian was born from the grassroots, and has experienced life and death, coupled with the knowledge of two lives, he knows that low-key is the king's truth, how can he make the mistake of being arrogant. The reason why he used the Escape Tissot to fly on the third floor of the Ten Thousand Clans Tower was just to save time, and now that there are natives who can threaten his own life, he will not give his life in order to save time.

Sou!

Like a meteor streaked across the sky, the Shadow Demon increased the altitude of the Escape Tissot in order to prevent the attack of the natives of the lake.

There is no need to worry about encountering flying races on the lake, as long as you escape into the water, you can get rid of those races that are good at flying, and Ye Tian already has experience in dealing with them, so he dares to fly swaggering on the lake.

An hour later, at the end of the horizon where the water and the sky meet, a sinuous green thread appeared, and the land arrived!
