Lao Zhang also found it here, only to see him quickly return from a distance, holding a handful of crystals with a faint red light in his hand, and when he got closer, it was actually a fire diamond the size of a thumb belly!

This made Bai Qi and Ye Qi very happy, you must know that a fire diamond is a supernatural person! It turns out that it can only be obtained by hunting high-level zombies, and it can't be used in large quantities at all.

The next few people began to search on a large scale, Bai Qi and Ye Qi searched for the unknown metal minerals, Lao Zhang continued to look for fire diamonds, and the progress was not slow under the division of labor.

It's just that the temperature here is too high, and the three of them need to use a lot of energy to maintain the protective shield, so they need to return to the gecko to rest in less than an hour, but fortunately, the energy here is abundant, and they can calmly absorb it with the breathing method, and it will also recover in less than an hour.

So a few people were out for an hour before returning to the Gecko, resting and recovering while sharing the new things they had discovered...

After 10 hours of busyness, all three of them were a little tired and decided to put off their actions.

Sorted out all the current harvests, after statistics, there are 209 fire diamonds, a total of 4 unknown metal minerals, a total of almost 400 kilograms of cyan unknown minerals, different sizes, judging by the color, similar to the nameless sword, it should be the target to find.

The other three are black, dark red, and light brown, and the quantities are not very large, 50 or 60 kilograms respectively, and since I don't know what they are, I collected some just for research.

After a brief discussion, the main target is still located on cyan minerals, and the collection of fire diamonds can be postponed for a while, and if it is really a batch of supernatural beings, it may not be a good thing...

After a good night's sleep, the three of them continued their work of collecting.

After another 10 hours of continuous work, the gecko's storage compartment was already full, and it was discussed to return.

Sudden mutation!

The originally silent underground world suddenly made a "boom" sound, accompanied by violent vibrations, and if it weren't for the gecko's limbs embedded deep enough in the cliff, it might have fallen off the cliff and fallen into the abyss.

The three of them couldn't figure out the specific situation, and returned to the Gecko as fast as they could, each full of countless conjectures.

Ye Qi is a researcher, his first reaction is the movement of the earth's crust, if this is the case, it may cause the crack in the ground to close, and several of them will definitely die.

After observing for a while, there was no geological change, but something more disturbing...

A deep roar came from the abyss below!

"Retreat!" Bai Qi shouted at Ye Qi, who was still in a daze.

Ye Qi came back to his senses, his hands and feet were carried out quickly, the propeller rotated rapidly, and the gecko, which was originally clinging to the cliff, broke away from the wall

Fly up......

Through the transparent image, you can see that in the bottomless crack, there is a small red point of light moving back and forth, judging by the size, it should also be traveling upward, and the point of light is gradually getting larger due to the change of distance.

Although I don't know what it is, it's definitely not something that a few people can provoke now, and if you don't do it, you will lose your life, it stands to reason that there is plenty of energy in the depths of the ground, and there are a lot of fire diamonds formed, the huge fire diamond that Ye Qi found before should be more than one, since Ye Qi The large fire diamond they found can attract zombies and mutant creatures, will the fire diamond hidden in the ground also attract those things, even if there is no large fire diamond, the abundant energy is also self-sufficient? So the depths of the underground will never be so dead, and if you make a bold assumption, the reason why there are no zombies and mutated creatures entering the underground is because there is enough to make them afraid of it below!

Bai Qi couldn't help but feel chills in his heart when he thought about it, and urged Ye Qi to speed up, but now that it was the maximum power, Ye Qi directly wished that the speed could be a little faster......

When it was about 10 kilometers above the ground, the red point of light chasing below gradually became smaller, and finally disappeared, no matter what it was, it should have given up the pursuit of the gecko.

But the nerves of the three of them were still tense, and they always paid attention to the situation below, for fear that there would be a sudden attack or something like that, and they didn't dare to stop much when they reached the ground, so they switched the gecko to the road form, and ran wildly for several hours before stopping to rest......

Originally, they had been riding the Gecko, but the three of them did not put away the protective shield of the body due to excessive tension, and did not react until they felt that the energy in their bodies was almost exhausted.

Bai Qi took a deep breath, "How many terrifying things are there in the last days of this dog." ”

Lao Zhang said with palpitations, "No matter what it is, it gives me a feeling that is even more terrifying than when I was facing forty at that time, at least when I was facing forty, under that kind of pressure, I can still arouse my body's instinct to resist, but that thing just now, except for running away, I don't have any other thoughts......"

Ye Qi took out a few bottles of water, threw them to Bai Qi and Lao Zhang, and unscrewed them and poured them a few times, and it could be seen from his trembling hands that he was still in a state of shock, "Whew...... Really, it was an eye-opener. Our lives are so comfortable! With the power we have now, it is completely the lowest end of the biological chain in this apocalypse, whether it is high-level zombies or those terrible mutant creatures, they are constantly evolving, and we, the human survivors, will be complacent after having this lowly ability, but we may die anytime and anywhere. ”

"Although we have found metal minerals that can be used to forge weapons, how to smelt and forge is also a big problem, and the temperature in the underground has exceeded 2,000 degrees?" Bai Qi asked.

Ye Qi thought for a moment, "This is not too big a problem, very."

Multiple technologies can achieve higher temperatures, but the underground world is also really strange, except for these special minerals, the cliffs don't seem to be affected in any way, as if that temperature is only scattered in the air, and it doesn't melt the rocks and stuff. ”

After asking this question, I didn't get any response because I couldn't figure it out at all.

After more than two hours of rest, the gecko was on the road again, without any stops on the way, and rushed back to the city in the city, during which he contacted Yang Tianfu once, and briefly said the harvest situation, but the danger hidden in the depths of the ground did not say, this kind of thing is not suitable for explaining in the communicator, once it leaks out, it may bring great panic, and the hope that has been established will be dashed, or wait for the meeting, it is better to gather all the main personnel to explain in person.

After Bai Qi and them left, three outreach teams also set off, and the fastest team was the team led by the Demon Guy, who had already made contact with the target, but there was no news yet, and it was unknown what the outcome would be for the time being.

In addition, the cobra is estimated to be able to reach the target gathering place in one more day, the slowest is Wang Xiaoshuai's side, stopping and stopping all the way like an outing, along the way do not forget to search for materials in some key material points such as hospitals, pharmacies, police stations, etc., and there is a small harvest, and there are a lot of antibiotics.

Wang Xiaoshuai's mind is also simple, anyway, when he comes out, it is still necessary to pluck the goose, even if he can't communicate with the target gathering place, it is not considered to be empty-handed, it is regarded as a field operation. It's just that the members who are with him are more uncomfortable, because Wang Xiaoshuai is too chatty, and he can talk a few words at the beginning, but then he can't wait to plug his ears......

……

Everything is going on as usual, except that in the underneath the city within a city, a terrifying scene is taking place.

The underground drainage system of C City and several surrounding cities was rectified in the past few years, because of a heavy rain that attracted national attention in the early years, which caused serious damage here, and the main culprit was the underdeveloped drainage system.

In the dim sewer, a big rat with about 200 pounds made a soft humming sound, this is the little mouse that came here with the gecko from J City, but the appearance at this time is very different, except for the huge size, it is lying on the ground, continuously giving birth to cubs, and it can give birth to one in tens of seconds, and the speed is staggering.

Every cub that has just landed is not ordinary, it is directly a complete body half a foot long, and it can run around when it gets off the ground, and its appearance is not the same, some have obvious mutations, and some have ordinary appearances.

In the distance, a small group of white rats ran from the end of the sewer to the side of the giant mouse, and they all had pieces of things hanging from their mouths, and put them next to the mouth of the huge mouse that was in production, so that it could tilt its head and eat it

Look, they are all the stumps of zombies, with severed arms, severed relationships, and even broken heads.

The huge rats did not refuse, and all of them swallowed and chewed in their mouths, and the "squeak" sound was incessant......

Batches of cubs are born, and then they run away to find food, and they are transported back to the mother, who then continues to produce them, which is simply a production line for making mutant mice......

After the gecko returned to the city within a city, all the main members gathered together and listened to Bai Qi tell them about the experience of the underground trip, and when they talked about the unknown horror, the others were only briefly surprised, they were surprised not by the horror, but by the fact that there were creatures deep underground?

didn't feel it, and it really couldn't understand what Bai Qi and the three of them felt at that time, so Bai Qi didn't elaborate too much, because that thing was not something that the current human survivors could fight against at all, even if they prepared in advance, they were helpless.

There are about 1,000 catties of cyan metal minerals, more than 200 catties of other three colors, and more than 300 fire drills, which is all the harvest of their underground execution.

The next question is to discuss how to forge, if you want to cast a weapon, you naturally have to melt the metal first, and the first choice is naturally to let Wei Chao try it.

Xiao Qi and Xingchen hurriedly went to Wei Chao to discuss, now he is an idiot with an IQ underground, and it is still a little troublesome to ask him to help, with a child-like mind, everything is done according to the heart, but Xingchen and Xiao Qi get along with him every day, and they can be regarded as having a certain ability to control.
