"This is a lord-level demon beast, just give it to me and I'll die."

"But there is a wound on its body that is very deep, very deep, and you can see that the heart is beating, and if this wound goes in a little further, this flame wolf will definitely die."

"The only chance I've waited for is to hit its heart with a throwing knife."

Xie Tian felt towards the entrance of the cave, and his mind was also thinking quickly.

Hunting in the wilderness for a long time, Xie Tian has seen too many examples of death due to greed, so Xie Tian also has his own principles of wilderness survival.

That is to never do something that you are not sure of.

This Lord-level Flame Wolf was very seriously injured, and it should have been injured twice.

The first injury is the most serious injury, and it is very likely that it was caused by a monster or a warrior of the same level.

The second injury should have been inflicted by the Tiger Squad, and the old injuries were added to the new ones, and they were all fatal injuries, which left the flame wolf's strength very little.

But if it hadn't been for the wound on its body that could see the heart, Xie Tian would still not dare to fight.

"It's really hidden enough~"

Soon, Xie Tian came to the mouth of the cave covered by dense rattans.

The entrance to the cave is tightly covered, and even if you stand in front of the entrance, if you don't know that there is a hole behind it, you won't find this hole at all.

Carefully flip over the rattan into the hole.

The light in the cave is very dim, but Xie Tian has already prepared for it, there are many kinds of things in the hunter's backpack, and there must be lighting things among them.

A few lighting balls were taken out, dimmed slightly, and then thrown into the hole, and suddenly the inside became brighter.

"This should have been a rock-eating rat's nest before, so this cave may be accessible in all directions, and I don't know if I can find this flame wolf."

Xie Tian carefully observed this cave, it was not a natural cave, but a cave formed by excavation the day after tomorrow, and there were still some remnants of demon beast fur and bones on the ground.

Rock-eating rats, a kind of social low-level demon beasts, are good at digging caves, and their reproduction speed is very fast, and they have formed beast tides to impact the base city many times.

"Could it be that the rock-eating rats here have been driven away by this lord-level flame wolf?"

While cautiously groping into the depths, Xie Tian also observed carefully.

The Rock Eater is a social monster, and this is the nest of the Rock Eater Rat, so it stands to reason that there should be a rock Eater everywhere, but thank God has never encountered any Rock Eater Rat.

So the only possibility is that these rock-eating rats were driven away by the flame wolves.

The cave is very deep, twisting and turning, and there are many forks in it, and this passage is extending all the way down, Xie Tian can only choose a road at will to go deeper and deeper inside.

After walking for more than ten minutes, the space to go suddenly gradually became wider, and at the same time, there was a faint light coming from the way there.

Xie Tian quickly turned off the power he was carrying, and then cautiously groped forward.

Soon, a huge cavern appeared in Xie Tian's field of vision.

It is a cave that is dozens of meters high and the size of a football field, and there are passages around the cave leading to unknown places.

At the bottom of the cave there are countless dry bones and tattered furs, most of which are demon beasts, evolved and mutated dry bones and furs, all kinds and types.

However, there are also a small number of human warriors and hunters' dry bones, tattered clothes, and combat uniforms, which can be seen clearly by thanks.

This is clearly the nest of the most central part of this group of rockivobies.

But the most striking thing is not these, but the tower in the middle of the cave.

This tower is not high, only a dozen meters, the tower has nine layers, from the top to look at the past, it is square, it looks very simple, it seems to be a very ordinary ancient tower.

But at the top of the tower there is a bead, and the bead is constantly shining brightly, and it is this light that illuminates the cave.

At the same time, faintly, there is still a millilight circulating on this small tower, and the aura in the cave is also richer.

"Tower?"

Xie Tian's eyes were immediately focused on the tower.

"How can there be a tower here?"

Xie Tian immediately frowned.

Obviously, this cave should be the deepest part of the rock-eating rat's nest, and thanks to God, it should be hundreds of meters deep from the ground.

There is a tower in such a deep underground, and this tower is very extraordinary at a glance.

"Is it a ruin?"

Xie Tian thought of a possibility, and suddenly his eyes couldn't help but light up.

Ruins, no one knows where these ruins came from, but with the revival of aura, some ruins have been discovered one after another in all countries of the world.

There are many types of ruins, some are inheritance ruins, some are assessment ruins, and some are treasure ruins, etc., scientists on the earth speculate that these ruins are very likely to be prehistoric civilizations or alien civilizations left on the earth.

The reason why it didn't manifest in the past is most likely related to aura, because most of the ruins need auras to keep them running.

In the previous earth, the aura was silent, and there was not enough aura to maintain the operation of these ruins, but now the aura has recovered, and these ruins have regained their aura, so they have begun to manifest again.

Thinking of the ruins, Xie Tian's whole heart couldn't help but beat faster.

Any relic is extremely precious, especially the inheritance relic, and the cultivation exercises in it are very desired by all countries in the world.

The tower in front of you is very likely to be a ruin, and it is an extremely precious ruin.

Because it is buried deep underground, I don't know how many years of erosion it has experienced, but it can still be kept so intact without the nourishment of the aura, which shows the extraordinary nature of this relic.

"Whew~"

Xie Tian took a deep breath and looked around carefully.

Soon, Xie Tian found the Flame Wolf.

At this time, the flame wolf is lying next to the tower, but it doesn't know its life and death, it seems to have come here to heal, the aura here is rich, and it is also helpful for healing, or this tower has the function of healing.

"It's not even dead~"

Xie Tian didn't dare to make any sound, and looked at the flame wolf carefully.

Soon, Xie Tian found that the flame wolf was still not dead, with a slight breathing, and his body was slightly undulating.

"I only have one chance to attack its heart with a throwing knife first, otherwise I will definitely die if I am attacked by it."

Xie Tian immediately frowned, clenched his flying knife, and locked his eyes on the wound on the flame wolf's body.
