The underground was supposed to be the basement of a residential building and the connected underground sewers, but now it has been hollowed out by the black squirrels and turned into an underground passage that extends in all directions, and Charlene can even see the traces of red bricks on the walls on both sides of the road, which are also covered with fluorescent moss. Watermark Ad Test: Watermark Ad Test

I don't know if it's because Du Qinglin had killed a lot of black squirrels when he was down there before, although Xia Lin saw a lot of black squirrel corpses along the way, but there were many fewer black squirrels attacking the two.

Charlene couldn't understand why the two creatures, the black squirrel and the black bear, lived together, and seemed to be ...... It's harmonious? Could it be that these two creatures can also be accompanied?

Shaking her head and shaking off this strange thought, Charlene reluctantly glanced at the vajra vine in her hand.

Although she was a little reluctant, but there was no way, with the force and skills she was not very good at in the first place, in an underground environment, if she wanted to cause damage to a group of black rats, it was obvious that the original stick could not do it.

In addition, she also has to be responsible for the part after the break, to ensure that those black squirrels can't get close to herself and Du Qinglin, and Charlene can only use it. After all, the whip has a much larger range than the club.

The two of them cautiously walked through this underground sewer that should have been a thousand years ago, and then was constantly excavated and transformed by black rats and black bears who had occupied this place for an unknown number of years.

In the end, according to Charlene's sensitivity to the fluctuations of energy stones, coupled with Du Qinglin's understanding of the habits of black squirrels. The two of them were in a place that was supposed to be the core of the black squirrel's nest, a place that looked like a large hall that had been dug up by a colony of black bears and black squirrels. Found the Power Stone.

And, of course, there's a sturdy black bear sleeping next to the power stone.

When she saw the crystal nucleus that was guarded by black bears and black squirrels as treasures, Charlene's mood was undoubtedly complicated.

In the last days, the competition between humans, alien beasts, and even zombies for crystal nuclei was already a very white-hot process.

After all, crystal nuclei not only mean energy, but also means power, and it means advancement. It is also the currency of the last days for mankind. Even more precious than currency.

But even at that time, because of the huge zombie base and the limitations of the human abilities at that time on the energy absorption and storage conditions in the crystal nucleus, the low-level zombie crystal nucleus gradually became a simple currency. Even something of little value.

Even later, even if she openly put away some low-level zombie crystal nuclei, it would not cause too much suspicion. After all, those crystal nuclei were already a powerful team to the relative surroundings she was in, and those who thought very highly of themselves would not take these low-level crystal nuclei seriously.

However, it is obvious that the situation at that time is not in line with the current situation, relying on the powerful scientific and technological ability and the gradual transformation of the genes of the later generations of supernatural beings, the absorption and utilization rate of the pure energy stored in the crystal nucleus by the human supernatural has reached more than 80%, and even the excellent storage of genes like Chu Ci, coupled with the top technology of the federal military, the utilization rate of the energy in the crystal nucleus. It has even been able to reach as high as 96 percent.

This is already a very scary number for Charlene.

If she absorbs all those crystal nuclei in her space, oh. No, it doesn't even have to be all, even if it's just a tenth, I'm afraid it's enough to advance to a terrible Cheng dù.

If it weren't for Charlene's clear that her spatial advancement had little to do with these energies, and her strange wood-based abilities were full of uncertainties, I'm afraid Charlene wouldn't have been able to absorb the energy within these crystal nuclei.

"Roar~" The black bear that was stabbed in the abdomen by Du Qinglin's spear roared angrily. The bear's claws gripped at the weak human in front of him.

It had been entrenched in this place for a long time, and no creature had ever dared to provoke it. Even the pesky black squirrels obediently offered their food in exchange for a nod to allow them to stay in this place.

But today, it was provoked by these two weak and thin guys.

Damn it!

I don't know if it's because of sleeping in this place all year round, this black bear is a little stronger than the black bear in Charlene's impression.

Of course, it may or may not be obese.

It's just that such a strong black bear does not have the clumsiness and sluggishness of those black bears in Charlene's impression, but is flexible and vigorous, moving in this hall that is not too big for the black bear in front of him, and even a little narrow.

Xia Lin didn't know if Du Qinglin had gotten any information about this kind of black bear in the dungeons they had dug up in the past, but even if there were, I'm afraid it wouldn't be sure, right?

After all, not all black brothers will rely on the energy of the crystal nucleus to cultivate.

Although in Xia Lin's opinion, this kind of thing that only relies on the faint energy radiated by the crystal nucleus to cultivate, no matter how you look at it, it feels incredible.

In other words, ashamed of the tyranny of the people of the year.

Each palm of the black bear's huge bear paw has an extremely powerful attack power, just looking at the depression pits on the ground and wall around her that were hit by the bear paw of the black bear, Charlene felt terrified.

Du Qinglin, who was dodging the black bear's attack on one side and constantly attacking the black bear on the other side, looked particularly weak and pitiful in Xia Lin's eyes.

The space in this underground passage is limited, plus there is the black bear and Du Qinglin fighting in the hall, she also needs to control it to avoid causing trouble to Du Qinglin, and the vajra vine in Xia Lin's hand wants to swing flexibly, and the strength required is definitely much greater than when she was in the dungeon.

Gradually, Charlene was a little overwhelmed, but looking at the dense black squirrel in front of her, and the black bear that was fighting with Du Qinglin on the other side, Charlene gritted her teeth and rushed forward.

Quickly shaking the vajra vine in her hand, Charlene gritted her teeth, trying to bring the words "fast, ruthless, and accurate" to the extreme.

In the battle with the black bear, she, who is very scummy in combat power, can't help much, and can even only become a burden, but at least, these black squirrels, she can still deal with them!

But Charlene is not an ignorant person who only knows simple stubbornness. Or rather, what she has always been best at is defense. Therefore, while cleaning up the black squirrel, Charlene did not forget to scatter the alien seeds in her hand on the ground.

Fortunately, when she was on the surface before, because she didn't want to waste it, and she couldn't bear to let those alien plants die in vain, Charlene still spent some effort to ripen all the alien plants that she had spawned, and then collected all their seeds.

Now, these seeds, which were not yet hot in her hands, came in handy.

Taking advantage of the gap, she poured a sip of space spring water fiercely, and at this time, Charlene couldn't care about whether she would have any unpredictable effects if she drank too much spring water.

She only knew that she didn't want to, didn't want to, and couldn't drop the chain at this time, let alone drag Du Qinglin down. Even, she hopes that she can help the other party.

Charlene had blocked almost all the holes around the hall that had been open in all directions, using the aliens that she had no advantage of at the black squirrel.

Even, when she saw that Du Qinglin was faintly a little weak, she boldly threw out the vajra vine in her hand and tied up the black bear!

Although it was only a few seconds, it was enough for Du Qinglin to take this opportunity to flash into the smallest hole where Xia Lin was.

"Well done!" Although he has been fighting with the black bear, it doesn't mean that Du Qinglin hasn't seen what Charlene did.

After all, even if these alien plants are not bright turquoise, they are still very conspicuous in this underground hall.

And after finding that he was invincible with two fists and four hands, and it was completely impossible to fully defend these black squirrels, he was able to think of this method, in Du Qinglin's opinion, Xia Lin still had some scheming.

Although, this ploy is not necessarily very high. After all, the cost of these alien plants is too great for another person to bear.

"You're hurt?!" Looking at the bloody wound on Du Qinglin's shoulder, Xia Lin was shocked.

"I'm fine." Du Qinglin glanced at the injury on his shoulder absently.

"I'll help you bandage it." Charlene bit her lip, but decided to take out the medicine and gauze from her space.

"There's no hurry." Du Qinglin shook his head, "Take the energy stone first." ”

"Can a power stone be more important than your life?!" Charlene glared at each other a little angrily.

"Of course." Du Qinglin just glanced at Xia Lin lightly, the kind of look that you are talking nonsense made Xia Lin choke.

"If you can exchange my life for the life of the major general, it will be worth it."

It's a pity, how can the lives of these people be compared with those of the major general?

Seeing Du Qinglin's categorical answer, Xia Lin found that she was a little speechless.

"Roar~" Seeing that the despicable guy who disturbed his sleep and even injured himself actually hid in a small hole and couldn't come out, the black bear roared angrily in the hall.

Even after seeing that the two had no intention of coming out at all, the black bear actually planned to stick the bear's paw into the hole.

The hole isn't too deep, and there's not even another exit, which is why Charlene chose this place. Therefore, seeing the movements of the black bear, both of them knew that they could not stay any longer.

Taking the water that Xia Lin insisted on, although Du Qinglin was a little inexplicable, he still drank it, and then turned around and rushed out again.

The moment the spring water was drunk, Du Qinglin noticed the difference. I don't know what kind of water Charlene put in, but it can help him replenish his energy quickly!

Even, it is faster than the potion provided by the highest scientific research institute of the federal military, and the energy is even purer!
