Su Yun thought carefully about the words of the virtual girl, she did have some truth in saying this, after all, she has no effective means of mining now, and it is undoubtedly a little difficult to dig a mine deep underground with a mining model of service robots alone.

And although the novice base was destroyed beyond recognition by the previous missile, after all, it is indeed full of raw materials for finished products, and even the step of refining from ore to minerals can be directly omitted, and raw materials can be directly produced by throwing them into the decomposition machine, which can be said to be extremely convenient, and that place is almost on the surface layer, and it is almost enough to use ordinary models of service aircraft to get everything done.

What's more, judging from the scale of that novice base, the raw materials obtained from recycling waste alone are completely enough to support Su Yun's needs at this stage, not counting the occasional things that can be used, in case anything valuable can be found, it can greatly shorten Su Yun's current work process, so it seems that it is not just a triple win, it is not an exaggeration to say that it is a million benefits.

Anyway, I have been considered by the system to be a red person who can't be in the red big red name, and I don't have to worry about lice too much, so it's better to ignore these and then get you something back to the cost.

The only problem is that there are still a lot of defense models of service aircraft working, which are not absolutely safe, and we must first find a way to eliminate this threat.

"Do you have any blueprints for your EMP weapon? It's better to be a bomb" Su Yun suddenly remembered what he had encountered when he went to the novice base to find refining equipment before, EMP Impact was so useful to deal with this kind of guard composed entirely of automated machinery,

"There is no design drawing, but I have the theoretical principles and analysis here, give me some time and I'll see if I can design a special model" The virtual girl immediately understood the meaning of Su Yun's words, changed into the previous research uniform again, and made a preparatory action with both hands outstretched, and then virtualized three screens in front of her, and devoted herself to her work,

Su Yun just had the attitude of trying it before, but he didn't expect the virtual girl to really be able to do it, and he was suddenly happy in his heart, so he finally didn't have to go down in person to fight with those service planes who thought he was the enemy, since it was a lot easier, it was naturally better, but looking at the appearance of the virtual girl, it was estimated that he couldn't do it for a while, and he really couldn't think of what to do, so he had to go to the high-energy crystal mine below to see if the operation there was still normal, and if there was anything that needed to be improved, After all, energy is the lifeblood, and if there is something wrong, it is yourself who is unlucky in the end.

The central control center is on the same floor as the opening of this base facing the mining area, so Su Yun doesn't have to take the elevator from here, and now the central elevator is being used as a freight elevator by the service machine to carry energy crystals, so Su Yun also deliberately reinforced this thing that was easily dismantled by himself before.

The service plane is completely floating in mid-air, although it seems that the elevator is completely unforced, but the physical rule is that the effect of force is mutual, although it is invisible, but there is still a magnetic field repulsion acting on it, Su Yun also has to be careful, for fear of causing some accidents because of his previous relationship,

Along the way, I saw two service planes conscientiously carrying energy crystals, and took the return magnetic rail car to the mining area, everything is normal in this place, except for the slight accumulation of fragments of high-energy crystal rough caused by the lack of refining machines, there is no problem with others, with the current efficiency, before the opening of that huge industrial center, there is no problem with the supply of energy,

Suddenly, Su Yun looked up at the cave where he originally came from in the distance, thinking that he had escaped from its body after being unlucky enough to be swallowed by the cosmic worm, and in order to avoid the cosmic worm, he chose to move in the opposite direction from it, and only then did he discover the current underground base, and at the same time caused the beginning of everything after that,

Looking back at this place now, this obviously artificially excavated passage leads to it specifically Su Yun himself is not clear in his heart, after all, the map of one hundred and sixty years ago does not indicate the specific direction of this place, and even this may have some inseparable relationship with the formation of this mining area at present, plus the previous cosmic worm caused a lot of shadow in Su Yun's heart, this cave more or less made Su Yun a little concerned,

frowned and looked into the distance, thinking about whether he should go over and explore it, or find something to seal it first, in case he recklessly summoned some cosmic demons, it was not a joke, in ordinary novels, this kind of development is not rare, I still have to think about it carefully,

After thinking about it, Su Yun decided to explore it, after all, if there is really any problem, the cosmic worm that broke into it before had already been triggered, and it was not his turn to wade through the thunder again, and as the old saying goes, wealth and wealth are in danger, and playing a game by yourself is still so cowardly, it is not manly at all,

It just so happens that there is plenty of time now.,I'm waiting for the virtual girl to get the weapon to deal with the service plane.,There's nothing to do at this time.,It's better to hit the day.,It's better to get this thing done now.,

Although this is the case, but sufficient preparation still needs to be done, first of all, the armor durability value of this set of bionic power armor on his body has bottomed out, and he has to change it, because the energy supply is enough, so Su Yun especially went to the maintenance center, hoping to repair this set of things on his body, after all, he can't throw it away if it is broken, Su Yun is not yet proud to this extent,

However, because the repair center lacks specific armor repair materials, there is no way to repair the armor durability for the time being, so you can only throw the bionic armor there first, and then complete the recovery work of the novice base, maybe you can collect enough materials to repair.

After this thing is done, I checked the equipment on my body a little, left all the things that I can't use for the time being at the base, and made a little space for the subspace bracelet, maybe I will encounter something I want to bring back later.

After confirming that it was correct, Su Yun directly followed the previous route back to the cave again, this time Su Yun can be regarded as a shotgun cannon, if he really encounters trouble such as cosmic worms, this railgun will definitely be enough for it to drink a pot, not to mention that Su Yun still has the liquid explosives he found before, this thing can be regarded as a big killer, although the number is not much, but it is more than enough to use it for self-defense,

Su Yun is also a lot more relieved to have these things around, and let the Q version of the girl turn on the global scan along the way, so that if there is really any problem, he can know in advance, the known danger in front of him is the cosmic worm that swallowed Su Yun before, but after all, that guy was opened a hole in Su Yun's body, and to that extent, even if he does not die, he is seriously injured, and the threat to Su Yun is not very big now, what he really needs to pay attention to is those threats from the location,

After all, this is in the universe, not the earth, and in some cases, even common sense is not necessarily applicable.

Touching the cave wall all the way forward, soon Su Yun came to the place where he had drilled out of the body of the cosmic worm before, and from here it was a completely unknown world in the past.

Su Yun cheered up and adjusted the light to the extent that he could barely see the road conditions ahead, anyway, he had the Q version of the girl's fully automatic radar, and he didn't need to judge the situation in front of him with his eyes.

Stopping and observing the surrounding situation all the way, according to the map provided by the virtual girl before, the place where Su Yun is now did not exist one hundred and sixty years ago, at least one hundred and sixty years ago.

What happened in the past one hundred and sixty years, who dug this tunnel under his feet, what was its purpose, why even if he dug this tunnel and connected these places together, he didn't have any contact with that underground base, how did that high-energy crystal vein come about, these messy questions filled Su Yun's brain, making Su Yun's mouth dry, but he didn't care much about this problem,

flustered and exasperated

But having said that, the length of this passage also exceeded Su Yun's original expectations, according to the information sent back by the Q version girl, Su Yun had stumbled forward more than three kilometers in this passage at this time, and according to the calculation of the horizontal angle, the deviation of this tunnel was more than six degrees, it is obvious that this place was not dug at one time, but excavated many times,

Although the underground environment is relatively stable, after all, it is very old, and the appearance around it has almost assimilated, if it weren't for the Q version of the girl to remind herself, it is estimated that Su Yun would not be able to see the mystery of it, but this kind of thing has no useful effect except for adding questions to himself and causing trouble, so Su Yun automatically blocked this information, and now he is still concentrating on hurrying.

I don't know how long it took, Su Yun mechanically continued to open his legs, people have an instinctive resistance in this completely dark and closed environment, although they can still eat it in a short time, but it is inevitable that there will be no negative emotions after a long time, just when Su Yun was thinking about whether to turn back here, the picture in front of him suddenly changed, the traces of artificial excavation suddenly disappeared, and what appeared in front of him was a huge natural cave,

Again?

It's not like a high-energy crystal vein where there is a light source that comes with it, so Su Yun can't see the whole picture clearly for a while, but the scanned picture sent back by the Q version of the girl shows that the volume of this place is even more than twice that of the cave that carried the crystal vein before.

What is this place?

Su Yun took a step forward, never thought that his feet would be shallow, he looked up and around before, and didn't pay much attention to the ground under his feet, but now he lost his balance in an instant, and the whole person rolled out and fell into a pile of liquid not far away,

Liquid?

Su Yun felt that he had fallen into a pond that was neither deep nor shallow, and struggled to stand up, only to find that this pond was only half of his body deep, and it was easy to stand up straight.

Only then did I realize that the touch of this thing didn't seem to be right, and the reflectivity was too good, the light source shone on it and shone on the metal, and I thought it was my own illusion, and I picked it up a little and looked at it in front of me, and found that the feel was very heavy.

Suddenly I remembered that I had seen this thing,

It's mercury.
