The Blood Sacrifice technique is not good at fighting under the ground, so I hesitated for a moment, and instead of continuing the pursuit, I turned back and returned to the vicinity of the Nameless River.

The gendarmerie and aviation brigades have cut down hundreds of large trees and laid the bridge decks between the piers.

Because of that strange fourth-order void-level demon beast, Jihua, who originally planned to go deep into that land and build a bridgehead after building a bridge, had to run aground.

The gendarmerie and aviation brigades were allowed to rest in place for a day, and then set off in the other direction.

This strange fourth-order void phase level demon beast can't be dealt with by me alone, and the next time I come, I will definitely pull Huang Tianhua and Lu Bu over. The Golden Light Roar Soul Diagram cultivated by the two of them has excellent defensive capabilities, and they should be very advantageous to deal with this kind of demon beast, and they are not afraid to fight deep underground.

However, I didn't immediately return to Chaoge City, it was not easy to come out, the time spent on the road was too long, and it was too economical to return empty-handed.

I have long planned to equip the aviation brigade with flying demon beasts, and since there is no way to complete the matter of establishing an advance base in the new city this time, it is worth the trip to go and get the flying demon beasts of the aviation brigade first.

The flying monster I selected for the aviation brigade is a nest of reborn birds in the gap between time and space, and the flight speed of the reborn birds, although slightly inferior to the goldfinch birds, is not as good as the free birds that can shuttle through the void, but it is still one of the fastest flying monsters, and the speed is more than 1,000 kilometers per hour, and it can fly at subsonic speed. Moreover, the strength of the reborn bird is strong, and the combat effectiveness of the aviation brigade equipped with this kind of demon beast will increase in a straight line, even comparable to that of ordinary main regiments.

I led the gendarmerie and the aviation brigade for seven or eight days before I found the approximate location of the reborn birds. Although I also knew that there were reborn birds in the gap between time and space, the specific range of activities of this group of flying demon beasts was unknown, and I could only determine the range of activity of tens of thousands of square kilometers.

After further narrowing the range of the reborn bird, I released the twelve Blood Yaksha that I had with me.

Although the Blood Yaksha has reached the third order, it can be comparable to the Reborn Bird in terms of flight speed, but with the Blood Sacrifice connection, these Blood Yaksha can teleport with each other as the target, and they are not afraid of the Reborn Bird hunting.

As for the three corpse birds around me all the time, there is no need to release them at all, the reborn bird is born to restrain the corpse bird in terms of ability, and the flight speed of the corpse bird is one-third slower than the heavy bird, if the corpse bird is gathered in a large group, it can also fight with the reborn bird, and the three heads in my hand are released, and when I meet the reborn bird, it is the "food delivery brother".

Not long after the twelve Blood Yaksha were released, one of the Blood Yaksha was in battle.

This Blood Yaksha encountered a Kui wolf, a rare monster beast but a jungle hunter with a very ferocious personality.

This Kui wolf is actually a second-order void-level demon beast, and the Blood Yaksha who touched it is unfortunately a first-order void-level guy, and a fight has started between the two, although the Blood Yaksha has a special ability and the ability to fly, and it is not lagging behind, but it is also entangled for a while.

I hesitated for a moment, and then I didn't pay attention to the battle between this Blood Yaksha and the Kui Wolf, although this Kui Wolf was one order higher than the Blood Yaksha, but with the Blood Yaksha's ability, he would not lose.

A few hours later, almost all of the twelve Blood Yaksha encountered battles, and most of the demon beasts that encountered Blood Yaksha were killed by this ferocious combat creature, and their soul power and vitality were devoured by Blood Yaksha, and even more than a dozen groups of life souls were snatched by Blood Yaksha, and they were all sent to the Blood Sacrifice for storage.

There were three battles, although they were still entangled, but it was also the Blood Yasha who had the upper hand, and only the Blood Yasha who was the first to encounter the Kui wolf still had no choice but to deal with this demon beast.

While the other Blood Yaksha continued to push forward, searching for the reborn bird, this Blood Yaksha stopped moving an inch, and finally made me lose patience. I switched to the Soul Diagram of the Nightmare and connected to the spiritual depths of this Blood Yasha through the seed of dreams, and the Nightmare Battle Body suddenly jumped, jumping from the spirit of this Blood Yasha to the spirit of the wolf.

The two innocence swords suddenly staggered out, and the two shijies who were bewildered by the coexistence of the virtual and the real were unable to resist even a move, and were directly killed by my spirit body.

The spirit of the wolf was killed, and the dream seed sprouted in the depths of its soul, and after a few minutes, the demon beast shook its head and ran to the side of the Blood Yaksha, like a puppy following its master, shaking its head and being cute.

I immediately gave the order, and the Blood Yaksha led the Kuiwolf on, and soon advanced more than ten kilometers.

With the help of these twelve Blood Yakshas, I quickly narrowed down my search, and after a day and a night, I finally settled on the exact location of the reborn bird's nest.

The Reborn Bird's talent is to manipulate fire, so it can't live in a tree like any other bird, but only on a stone that can't be burned by flames. But this nest of reborn birds is in a special situation, they also live on a big tree, this big tree has no leaves, only a fierce flame, looking at the past from afar, like a huge torch.

When I searched before, I focused on the mountains, and I missed this plain several times, which was a waste of time.

When I saw this big tree from the perspective of a Blood Yaksha, I couldn't help but be amazed.

The plant-based demon beasts I have seen are naturally the most Eternal and Illusory Trees, not only as high as the sixth-order void phase, but also towering to the sky, and now they have grown to more than two thousand meters, surpassing any human building of Lord Shijie.

But this giant tree with fire all over its body is not much inferior to the Eternal and Illusory Tree, it is also a fourth-order void demon beast, and the flames on its body complement each other with the reborn bird, so this big tree has almost become the country of reborn birds, flying up and down, there are at least forty or fifty reborn birds, which is ten times more multiplying than the nest in Fengming Mountain outside Xiqi City.

I don't have any information about this Flame Demon Tree, and I don't know what kind of tree it is.

It is almost 700 meters tall, but because its canopy is not a leaf branch, but a fierce flame, the height of the ups and downs, sometimes a single breath, the flame crown can soar thousands of meters, sometimes the flame crown shrinks, and it may be as low as 500 meters.

This flame demon tree is red all over, dozens of meters thick, and the ground near it has been melted by the flames into a lava pool of about a kilometer, just looking at the dark red magma rolling in the pool, you can guess how high the temperature of that place is.
