Si Fan, who was in the jungle, had no time to take care of so many things, and he was now in trouble.

Walking into the jungle near the South Pole, the jungle should be lush and green, under the shade of green trees are countless killing machines, mosquitoes are easy, and those powerful predators are the most difficult to deal with.

The most disgusting place is here, there is no trace of man on this island, he has no place of his own, he is an alien species, so the local creatures are still a little tempted.

It's just that humans have always been at the top of the food chain, and the beasts in the jungle will run away when they see humans, and they are afraid of firearms.

But now, none of these animals knew what a firearm was, only that it was a fat mass.

It is conceivable that this road is almost bloody, and this is only when it reaches the central basin.

Said to be a basin, in fact, is a big pit, the sinkhole is not counted, it is more than ten meters deep, from the top down, there are no green trees below, only a piece of strange crystals, from a distance it looks like crystal, and it is a mountain of crystal, but if you look carefully, the quality of this crystal is a mess of garbage, it can be said that it cannot be used to make decorations at all.

The crystals are crystal clear, but the inside of these crystals is all kinds of grit and various impurities, and there are some condensed metals mixed in them, some of which are quite attractive, and some of which are simply unsightly.

Standing above the basin and looking at this magical land, the place that Si Fan's eyes saw was a crystal valley, although it was not very beautiful, but there were still patches of glow under the sunlight.

Looking at the fertile soil in front of him, Si Fan believed in the prompts of this system even more, there were special elements that he needed to look for.

Si Fan looked at the environment around him, there was a vast forest behind him, and not far away near the cliff, there were a few old trees.

I can't tell what kind of tree it is, it's just very tall, and it takes about three or four people to embrace it, and I don't know how long it has been.

Si Fan looked at it, then looked carefully, found a big tree that looked the most reliable, and then took out the rope from the Terminator's body, and then wrapped it around the big tree.

The rope is an important material that every expedition team must prepare, this thing is equivalent to a second life when exploring, it can cross many obstacles, and the rope buckle can play a lot of roles.

Si Fan is ready to rappel now, using the rappelling lock of the rope and hanging it on his body, as if he was descending like a special soldier on TV.

The speed is very fast, everything is dependent on the lock on his waist, leaning back to ensure the balance of his body, and he must not be head-down.

More importantly, the feet should constantly look for a foothold, be bold and careful, and have a sharp vision.

This is what Si Fan learned in class, and now it is really easy to use it here.

This cliff is simply straight, without too many protrusions, as if it has been chiseled by a knife and axe, the walls are full of all kinds of creepers, plants are everywhere, and it is easy for Si Fan to reach the bottom of the valley.

As for the Terminator, this guy was even more relaxed and jumped straight down.

And when he jumped, gas erupted from his body to relieve the impact.

So by the time Si Fan reached the bottom of the valley, there was already a creature here that looked like a wild wolf, but his mouth was larger and his two fangs were longer.

In the face of the beast, Si Fan didn't have much experience, he just knew that he had better provoke less, so he quickly fixed the rope next to him, and this rope would have to be used to go up for a while. So it can't be put away at all.

Just down, you can clearly see that the distance is a crystal jungle, from above it seems that there are not many fragments, but now it seems that this is more than a person high crystal, but the inside has always been foggy and looks very disgusting, and even some of them are dark green, some crystals are broken, and the dark green is actually a viscous liquid.

It's just sticking to the outside.

It was disgusting to look at, and Si Fan didn't even want to touch it.

But when he saw the liquid in the crystals, the system beeped.

"Dingdong, congratulations to the host for discovering the B72 mining family C1F6 scarce pure proton mine. This mineral can be used to strengthen glass with ultra-high strength, greatly improve toughness and plasticity, and surpass steel in all properties. ”

"The system prompts that the host needs to build a synthesis factory to use the raw material, which does not appear now, and needs to be explored by the host. ”

After the system's prompt is over, Si Fan is about to vomit blood, what is the situation, what kind of proton is coming out, what is that thing, he really doesn't know, he is a person who is engaged in construction. Now it's even the building materials that are taller.

But if you don't do it, how can you build a building that completely surpasses this era, the so-called modern architecture, modern machinery, modern everything is based on material science, and materials are the foundation, so Si Fan has so many factories now.

The most basic function of the garbage treatment plant and sewage treatment plant is to refine more materials for Si Fan, so that he can use more materials in his construction.

Now, there is one more hint of synthesis, which can be regarded as giving Si Fan one more idea.

"Alas, it's a long road, Lao Tzu is doing the task slowly! It seems that these things are the B72, and I don't know how it will work after it is finally done. ”

"System, how should this thing be collected, and purified after all the crystals are removed?" Si Fan continued to ask.

The system's answer this time is very simple.

"Please dig up the crystal in its entirety, and after cutting, it must be sealed in a vacuum space, otherwise it will produce chemical changes and lose most of its effect. ”

"Hold the grass, fortunately Lao Tzu asked, otherwise wouldn't it be a pit!" Si Fan said with some surprise.

Then look at these crystals are a little big, how tall the crystals of this person are buried in the ground, who knows how big it is below, whether the whole is connected together, and it looks like a lot of crystals have been cracked, that is to say, the substance inside has come into contact with the air, and has lost its effect.

This crystal jungle must have encountered a lot of things back then, so that such a miraculous display of the Creator appeared.

"Forget it, anyway, Lao Tzu has already taken over the task, and then let the scientists be busy, why spend money to hire so many scientists for? Isn't it just for them to work?" Si Fan whispered as a matter of course.

"Didi!" At this time, Si Fan also heard the prompt tone of the phone, which was the positioning and gambling information sent by the two princes.

The distance between the two people has begun to gradually get closer.
