After seven or eight hours of searching for this unknown alien planet, when the sun was about to set again, I finally found a fairly secluded and safe place.

But it is a cave hidden behind the waterfall, which looks somewhat similar to the Huaguo Mountain Water Curtain Cave described in Journey to the West, although the entrance of the cave is not large, the internal space is quite large.

The entrance of the cave looked like it was only more than two meters high and one meter wide, but after entering the cave, the inner space became larger and larger as you walked along the passage.

After advancing more than 100 meters along the winding passage, he arrived at a space more than 30 meters high and 20 meters wide, and did not find any other passage, but it was a closed space in the belly of the mountain.

The walls of the cave are all hard granite walls, but some of the crevices have springs sticking out, creating a small pool of crystal clear water on one side of the cave.

The most amazing thing is that it was also discovered that there seems to be a phenomenon of ghost energy convergence in this cave, and the intensity of ghost energy here is three or four times higher than that of the outside world, and the effect of practicing qi here will be quite good.

Curious, he quickly expanded his divine sense, carefully perceiving the situation of the cave, and did not find any magical substances, but found that the structure of the entire cave wall was quite special.

The cave turned out to be a fairly perfect pyramid shape, and it seemed that the rather smooth rock wall formed a partial energy reflection, which in turn caused the originally low intensity of ghost energy to form repeated refractions in the cave, and the intensity increased a lot......

To be honest, I really suspect that this cave was excavated by hand, but I looked closely at the rock walls but I couldn't see any traces of artificial excavation.

Maybe it's too long ago to see this, or maybe it's all just a coincidence, but in any case, this is definitely a borderless place now, it's just a cave built for itself, and this kind of place shouldn't be unreasonable.

As for the shortcomings of this cave, it is that the environment is slightly damp, and the roar of the waterfall echoes in the cave, which is a bit noisy.

However, this matter is not difficult to solve, as long as you can set up a corresponding formation near the entrance of the cave, not only to isolate the entry of sound and water vapor, but also to create a force field barrier to completely block the invasion of all living things......

After making up his mind, he immediately got busy, and first arranged a triple comprehensive formation near the entrance of the cave, which not only isolated the sound and various radar detections, but even formed a force field barrier.

Of course, for the sake of safety, even on the rock wall in this cave? The Zhou Tian Star Dou Great Array that arranged the comprehensive upgrade Ban? Further enhance the ability to gather the spectral energy.

——

After having a relatively safe place to stay, finally have some leisure time? Take out that pale golden crystal the size of a goose egg? Take a closer look.

The result was the same as the result of the hastily perceptual analysis at that time, the content of the strange matter in the crystalline material? It can be said that it is quite rich.

If this spar, which weighs no more than two hundred grams, is completely separated and extracted, it should be able to synthesize more than a dozen grams of high-grade formation materials.

As for the other piece that was forcibly dug up when he fled? The purity is about the same? The mass is more than three kilograms, so these two large and small spars, all refined, should be able to obtain three or four hundred grams of high-grade materials.

After only two days in this world, you have gained so much? It stands to reason that I was a little excited. It's just that the thought of the piece of raw ore that may contain tens of millions of tons of spar was directly snatched away by the Zerg in person, and I was still depressed to death.

If you have the ability to successfully occupy that piece of ore and successfully extract the strange substances inside, you can even get ten tons or eight tons of high-grade formation materials......

Of course, there are no ifs? In fact, with his current ability, even if he gives himself such a large piece of citrine? It seems that he can't hold it, isn't it overwhelmed by the crazy Zerg? It was snatched by the Terran forces.

In the face of huge interests, the self-limiting killing of the same clan is not at all more merciful than the war of humans and insects? So you really want to occupy such a mine? Discovered by human forces? Nine times out of ten, they will come and grab it.

In the final analysis, their own strength is not strong enough, to be precise, the weapons and equipment prepared are not strong enough, if you have predicted that this situation will be encountered, you should really prepare a few tactical nuclear bombs.

As for the problem of manufacturing tactical nuclear bombs, in fact, it is really not more difficult than making the power armor, and it is even much simpler.

I have all the data on the structure of the nuclear bomb and the critical point of the nuclear explosion in my notebook, and the most difficult thing to make a nuclear bomb is to separate and enrich uranium from the material, but I happen to have an extremely strong ability to separate and enrich the synthesis of materials.

With the help of True Qi and Mental Force Field, strange substances can even be directly separated from monster corpses, and most of those monster corpses contain less than one part of a hundred thousand strange substances.

Such a low content can still separate the strange and singular and enrich the processing to obtain the top formation material, so it is indeed not difficult to separate enriched uranium from uranium ore.

It is even possible to extract enriched uranium from nuclear waste from nuclear power plants, so having time to quietly build a few tactical nuclear bombs is not as difficult as it seems.

If several tactical nuclear bombs are prepared for this operation, when the crystal ore is robbed, directly start the time pause, and drop the tactical nuclear bomb into the channel to detonate.

The Zerg that came out would definitely be blown up, and the tunnel that opened would completely collapse, and the Zerg would not be able to pass for a while.

Of course, the crystal ore may also be directly blown into powder, but the Zerg will not be able to pass for a while, and they will have time to quickly collect those powders.

When the Zerg comes, you can get a ton or two of materials, and if you don't think you have collected enough, then throw another tactical nuclear bomb to delay time......

……

Shaking his head, he shook off the unrealistic YY, gathered his mind and began to input his true qi into the hedron.

With the continuous input of true qi, the spar in his hand cracked after blooming with dazzling golden light, and then turned into powder flying in the sky......

The telekinesis field quickly formed the same frequency resonance with the strange substance, and the powder containing the strange substance was quickly introduced into the bottle, but the pure impurities fell directly to the ground.

However, the preliminary extraction of more than 200 grams of spar was completed in a few minutes, and the true qi consumption was less than ten percent, of course, it had to be purified and synthesized many times in the follow-up before the top-level formation materials could finally be obtained.

However, the extraction of this kind of spar is really very simple, if there is a vein to extract ten catties and eight catties a day, it is not a problem at all, so if you have the opportunity, you still have to go out and try to find some crystals, and strive to completely fill the space backpack before going back.

Although it is not possible to occupy a mineral vein now, it is still possible to secretly mine some mines, and thinking of a better future, this depressed mood is also much more comfortable.
