Xiao Yu saw that there was indeed nothing wrong with Xiao Jingqing, so he finally put his mind at ease.

It vaguely knew something, no wonder how an ordinary person who didn't have those cow backgrounds at all, let alone any talent, could turn on the ability.

Being able to turn the curse into a great opportunity for herself, this heart is indeed worthy of the achievements she has now.

Su Xin found that the inside of the monster's body was completely shattered, rotting into a mass of meat sauce.

…… Holding back the feeling of nausea, Su Xin only pulled out the soul stone.

When you're hungry, let's see if you can use it to make meatballs or something.

Soul stones are a good thing, not only can they improve their soul power, but they can also be used as energy stones.

Ever since Su Xin knew the principle of the base's "perpetual motion machine", she didn't dare to touch a piece of soul stone in the base.

But it's different here, it's not in the circulation system of the "perpetual motion machine", and even if you don't pick it up, you'll still be cleared by the next wave of monsters.

As she learned more about this place, Su Xin gradually understood why she was here.

Because the base defense consumes too much energy, and at the same time, it is impossible to recover more soul stones, and there is not enough energy to make up for the loss, so it will collect energy from the world inside the plane through some kind of trajectory.

For ordinary people living on the planet, when the severed head incense falls on their heads, it is simply a catastrophe, how "innocent".

I even feel that those plane battles have nothing to do with me, and besides, why do so many people in the world fall on my head, why do I have to sacrifice my soul.

Even now, after seeing so much and knowing the "truth", she still feels helpless that ordinary people can't control their own life, death and fate.

But many years later, when Su Xin looked back at the incident again, she finally had a different perspective.

In fact, according to the defense system of this base, its energy source is obtained from enemies, such as the corpse of the monster killed will be broken down by the spikes under the city wall, and then enter the circulation system.

An even more important source is the energy supply from the plane.

When the vitality in the plane reaches a certain level, the life energy generated is enough to maintain the energy required by the base station.

However, when the vitality in the plane is reduced to a certain level, the soul power will be directly extracted from the living body.

……

Su Xin's divine sense has improved a lot now, but it is still a little worse than Xiao Yu's natural sensitivity to breath.

It locked onto the direction from which the demonic aura was coming from, and approached cautiously.

In the distance, a huge ball of light appeared on the horizon.

The voice of the little gluttonous sounded in the sea of knowledge: "That's the interstellar portal......"

Su Xin stared into the distance, as if he had split the closed world in half.

"I didn't expect them to build a permanent teleportation station, and it seems that this defense base station is inevitable."

Even from such a distance, you can still vaguely see a steady stream of faint monsters emerging from the ball of light, seemingly chaotic, but in fact they are all arranged in an orderly manner.

Su Xin subconsciously swallowed her saliva, the monster was far more organized than she imagined, far from being a random provocative move that could make the other party scatter the stragglers.

Su Xin turned her head to look at Xiao Yu who was sitting on her shoulder, Xiao Yu was staring straight into the distance, his eyes flashing with a strong battle intent.

These are just the lowest-level monsters of that plane, which are used as cannon fodder to take the lead, and if they were placed in the past, they could be swept away with one incarnation......

Su Xin actually saw the gloomy feeling called "hero's end" in the other party's eyes, so he gently patted the other party's head to comfort him.

As long as you keep forging ahead, you have a chance to stand on the top of civilization again... By the way, I enjoyed the feel again, well, it was so fluffy and slippery, so comfortable.

"What did you mean when you said it was a permanent portal?"

Xiao Yu turned his head and said in a low voice: "Generally speaking, the distance between the stars is very far for ordinary life, and the distance between planes is even farther, even for cultivators, the time consumed in the universe travel is too wasteful, and it is also easy to be affected by sudden accidents, such as stellar storms, nebula collapses, etc., so in the end, I studied an interstellar impulse to penetrate a space-time tunnel through powerful energy, as long as the coordinates of another point are located, You can quickly teleport to your destination through this wormhole. They set up portals at the destination, which is very expensive, but it is very cost-effective if you want to teleport frequently and on a large scale...... Therefore, their real purpose is to completely conquer this primary plane and become their cultivation or material supply base. ”

In short, use this plane as a feedlot.

Su Xin couldn't imagine what it would be like for those monsters to drive straight into the living planet of the entire plane...... That is the real end of mankind.

Su Xin grabbed a point in Xiao Xin's words and asked, "You said that this portal was established, which means that it can be destroyed?" ”

The glutton's head turned to Su Xin faintly, "Destroy? ”

When Su Xin saw the other party's appearance, she was inexplicably a little weak-hearted, she really thought so in her heart. But the reality is that it's like a mantis arm as a car. The voice was a little weak: "Okay? ”

Xiao Yu stared at Su Xin tightly for a while before saying, "Try it." ”

I have to say that "newborn calves are not afraid of tigers" is really appropriate, those who don't know are fearless, it is precisely because it knows how powerful it is, so it did not think of destroying this portal from the beginning. However, when Xiao Jingqing was about to be destroyed as soon as he took his mouth, it inexplicably had a feeling of surging blood, yes, although it was a little difficult, but it was not impossible.

Once this portal is destroyed, it will take at least a few hundred years to build another one, and this war is already costly, so it is difficult to say whether another portal can be built at that time.

At this moment, a team of about a thousand lizardheads crawled towards this direction.

Gluttony: "They're here to clean up the battlefield, these monster corpses are a big tonic for them, eating these will make at least half of them advance..."

Su Sin: "So what do we do now?" Let's fight? ”

Xiao Yu: "These vanguard troops are all thick-skinned and thick-skinned, and they are used to step under the city walls, and it is difficult for ordinary attacks to break through their defenses. There's only one way to kill ......"

"What's the solution?"

"Find out where their soul stones are, and attack them directly......"

Su Xin nodded solemnly, his eyes blazing, "Well, I understand." ”

A man and a cat rushed towards the monster in front of them.

This is Su Xin's first fight since the foundation of washing the muscles and cutting the marrow, not only does he have all his perceptions keenly, but his skills also seem to have a talisman bonus.

The glutton pinned down the monster in front, and Su Xin sneaked up from the side and hit the key point.

The two are obviously working together in the real sense for the first time, and they have an incomparable tacit understanding.
