Xiao Yu's Void Step is extremely powerful, jumping from the spatial level is almost equivalent to teleportation, but the demand for spiritual power is extremely great. Xiao Yu cast a hundred Void Steps, which was enough to move a distance of more than a hundred miles, but he needed to complete a hundred Void Gazes to distort the space, and a hundred Void Gazes, even for now, would consume a considerable amount of spiritual energy. The Void Step may be good for escaping, but it is obviously not suitable for long-distance travel, so it is better to use the Sky Wind to drive.

Walking through the coniferous forest to the mountains, more than half of the spirit had been consumed, and the sound of the battle between the remnants and the two fierce beasts could no longer be heard at all. Xiao Yu's mental wear was too great and he had to stop first. The distance now is enough to ensure safety, and even if that tough orc has the ability to reach the sky, he will definitely not be able to catch up in a short time.

Gurion was killed by Xiao Yu himself, bringing a large amount of loot harvest, but also reducing a big crisis. Xiao Yu is now completely free, and two choices are placed in front of him for him to choose, the first is to find a teleportation array, return to the third layer, and return the same way, leaving the island. There are too many strong people in this place, most of them are old monsters who have been on the side for hundreds of years, and they have gained enough from this trip, so they are no longer greedy, and it may be a wise choice to protect themselves. The second option continued to return to Bloodfang's side as a Blood Thorn, and with the help of his power, he waited for the opportunity to seize the Heaven Replenishing Stone or other treasures while the major powerhouses were fighting each other.

Xiao Yu didn't think much about it, if he returned out of fear, then it would not be his style. Now that I finally reached the fourth floor of the sub-god palace, such a magnificent underground ruins, I don't know how many rare treasures are hidden, if I just flee like that, I will inevitably leave a big regret.

Anyway, fight again!

Xiao Yu has never been a timid person who is afraid of death, he first observes the surrounding environment, and the fourth layer of the ruins is undoubtedly a subspace. The so-called subspace is an independent space-time that is opened up on the basis of the original space. Every race has a secret realm of inheritance, and the secret realm of the void is a kind of subspace. The subgods are the only race that is free to create subspaces, and in the subspaces they create, they can modify some of the laws of the world to shape an ideal living or repair environment.

In the final analysis, subspace needs to be attached to real time and space, it is not the real world, but only a sub-world extending from the main material world, and when the main material world is destroyed, all subspaces will cease to exist. It takes a lot of energy to maintain the subspace, which is why most subspaces can't stay in it for a long time, and if they lose their energy supply, the entire space-time will collapse.

The Void Secret Realm can be divided into two kinds, a semi-illusory realm where spirit and matter are mixed, and a true illusion realm of pure spiritual energy. Most of the secret realms in the world belong to the former, and the things in the semi-secret realm can't be brought out, but they will be injured and die, and only a few are true illusions, such as the illusion hall and arena in Canglong City, even if they die in it, people will be fine.

The subspace on the fourth floor of the ruins is not an ordinary void secret realm, it is a truly independent material space, every flower, grass and tree, all of which are real, including the terrifying three-headed Chimera Dragon, including the powerful eight-armed golden python, this place can even be immigrated, in case of a huge disaster, you can move into this place, then as long as you guard the island, all threats from the outside world will not affect here. The subgods are truly a race that works miracles.

Xiao Yu's heart moved.

If a group of humans are infiltrated here, the young people will grow up here, and when they grow up, they will go out to experience and increase their strength. Then as long as the monsters on the fourth floor of the ruins are cleared, this place is undoubtedly a paradise where human beings can safely reproduce and develop, and the problem of human extinction will be solved!

Xiao Yu also found that the space on the fourth floor of the ruins was very stable, did this mean that the space scroll could be used?

As long as you can use the positioning scroll, Xiao Yu's safety factor will be greatly increased, so you can go on an adventure with confidence. Even if you can't defeat them, you won't have a problem escaping with a scroll. Xiao Yu took out a scroll of returning to the city and hit it with spiritual power penetration, and the scroll was successfully stimulated, emitting a silver-white light.

Xiao Yu was overjoyed in his heart, and when he tried to launch.

The scroll of the return to the city lit up with a white light, and then with a bang, it turned to ashes.

"No, the power of the space scroll is too weak to teleport out of the subspace!"

Xiao Yu analyzed the reason: although the spatial energy is stable, the spatial separation between the subspace and the outside world is too thick, and it is impossible to achieve teleportation with the power of the scroll alone.

During the war with the Sea Clan, Ask Sky City once obtained a teleportation tower. Xiao Yu originally wanted to build it in the Abyss, so that Wentian City could connect with the Abyss World, so that it would be convenient to smuggle and resell the resources of the Abyss World and the Dark Continent.

Now it seems that the value of the fourth layer of the ruins is also huge, the teleportation tower is gone, and the island has been placed under a huge ban by the subgod clan, I don't know how many years it will only appear once in the Black Wind Sea, if you miss this opportunity, it will be difficult to have a chance to enter this place.

Xiao Yu took out the goblin's spiritual reconnaissance instrument and injected spiritual power, the surrounding terrain and landforms were presented in his mind, the outer layer of the subspace was surrounded by forests, and the middle part should be a circular mountain forest area, and the passage to the fifth layer must be in the central part.

Xiao Yu floated into the air and flew towards the central area of the forest, the magical energy in the mountains and forests was abundant, giving birth to a large number of precious rare birds and plants, this is a living treasure house. He first found a safe cave, took out the teleportation tower construction order to activate, and a construction circle appeared on the ground, and a teleportation tower as white as jade appeared in the cave.

The teleportation tower is available, but it is not yet possible to teleport, due to the distance, the teleportation tower will not have a direct connection with the Epic Tower, and it needs to be activated with a spatial location token before it can be used.

Xiao Yu took out a few magic scrolls and laid several layers of prohibitions in the cave, after walking out of the cave, his eyes fell on a moss-covered boulder in the forest, his eyes gradually turned silvery-white, a spatial force wrapped the boulder and slowly rotated, a whirlpool rolled the boulder into it, and at the same time a boulder erupted outwards at the entrance of the cave, and with a bang, the moss-covered boulder blocked the entrance of the cave.

Find some vine branches for cover, so you don't have to worry about being discovered or destroyed by monsters.

After Xiao Yu finished everything, he rose into the air, and after about half an hour, a small clearing appeared in the woods in front of him.

A wave of magic power attracted emanated from there, Xiao Yu was attracted, and immediately headed in that direction, a large area of turquoise strange grass appeared in the field of vision, the number of which was hundreds, irregularly distributed in a basketball court-sized place, most of which were blue, and more than a dozen were shrouded in purple light.

This is Jingyuan Grass, which is the main material of Jingdan. Only the essence grass that grows for twenty years can be used for alchemy, and the essence grass that grows for more than two hundred years will turn purple. Although the Purple Essence Grass is only a one-star epic material, it is not particularly rare, but after all, it is the most important material for the Essence Replenishing Pill, and its demand is very huge, and the Purple Essence Grass is difficult to acquire among humans.

I have never heard of it, Jingyuan grass can grow in patches, and it is related to the environment of the subspace. The essence supplement is extremely practical, especially in this environment!

Xiao Yu looked carefully, in the center of the hundreds of purple essence grasses, he actually saw three golden essence grasses, the essence of the grass will only turn golden after a thousand years of growth, it is a five-star material, it can refine the golden essence pill! The Golden Essence Replenishing Pill can restore most of the spiritual power of a fifth-order mid-to-late stage powerhouse! The difference between the two is only one level, but its price is more than ten times more expensive than that of purple essence grass, and it is extremely rare, and there is no market for it!

"God help me."

Xiao Yu was about to go up to collect medicine, when a roar sounded in the forest, and a saber-toothed dragon jumped out of the woods. It is not protected by scales, it is covered with a thick metal hard shell, and it has a large number of modified features, it is obviously also a descendant of a certain work of the sub-god clan back then, and its strength is about the early stage of the fourth order, Xiao Yu turned on the bullet time, and slashed at its head. With a bang, Xiao Yu almost sprained his hand, and the metal saber-toothed dragon's head was split with a deep mark, but it was not fatal.

The saber-toothed dragon's shell was too hard, and it didn't suffer any damage, but Xiao Yu's sharp slash was enough to make it dizzy for a while. Xiao Yu took this opportunity to summon the Demon Suppression Purple Mountain, which became larger than fifty zhang and pressed down heavily, and with a bang, the saber-toothed dragon was originally pressed into a meat patty.

Xiao Yu took back the Demon Suppression Purple Mountain, but his heart fell into a deep groan, the creatures on the fourth layer of the ruins really couldn't look at it from a normal perspective. The strength of this saber-toothed dragon is at most the early stage of the fourth order, but its defensive power is comparable to that of the Purgatory Wyvern, and ordinary fourth-order warriors can't help it at all. The saber-toothed dragon didn't drop anything of value, and Xiao Yu picked up the essence grass and left here.

Getting closer and closer to the central area, it is estimated that you will be able to find the entrance to the lower level by going a few hundred miles.

Xiao Yu released the healed butcher and turned him into a bloody spur, while Xiao Yu hid in the space ring as usual. Xiao Yu asked the butcher to disguise himself well, cut off an arm, his shoulder was shot through by the attack, and a large number of scars were simulated all over his body, as if he had just experienced a vicious battle.

When everything was ready, the butcher moved on.

In the middle of the four floors of the ruins, there is a huge square with an area of about hundreds of thousands of square meters, the area is much larger than the ** square, the floor is completely paved with white stone slabs, standing in the deep mountains but spotless. There is a pyramid-like building standing proudly in the center of the huge square, the shape of the pyramid is different from the Egyptian pyramid, but it is somewhat similar to the Mayan pyramid, the flat top, the tower body is square, the bottom is large and the top is small, layered, and a castle is built on the platform at the top of the tower.
