Overlord: Rise of the Zerg

The existence of sulfuric acid rain actually explains many things.

It at least shows that on Planet 4, there is a high probability that there is water that can be produced by chemical reactions.

If this has been the case since ancient times, then a unique material cycle should have been formed on this planet.

How it works specifically remains to be explored, but the top priority is still to find a safe place for the Zerg units to land on Planet 4.

It is worth mentioning that due to the particularity of the environment here, Zero did not throw all the Zerg units onto the surface like they did on Planet 2, but divided it into two parts. Thousands of Zerg space units landed first as the advance team, while the rest of the Zerg swarm stayed quietly in the synchronous orbit of Planet 4, waiting for the next order.

Although even if all the first batch of Zerg units that land are killed, it does not mean that the colonial activity has failed. However, in the early stages of colonization, unwarranted losses will undoubtedly prolong the time for gains, so losses can still be avoided.

After all, here, if they cannot obtain supplies directly from Planet 4, they will need to spend a lot of time and energy to obtain them from the "Moon" base behind them, which is almost equivalent to sending a team here again.

After Zero conducted an on-site survey of the surface, his initial plan was to let the Zerg return to their roots, dig underground, establish a Zerg base under the ground, and then move on to other plans.

But he soon discovered that the crisis from the surface could not be avoided by just digging a hole deep into the ground.

Years of acid rain corrosion have completely softened the surface here. All substances that can be dissolved and corroded no longer maintain their original properties. They either evaporate into the atmosphere, or dissolve and seep into the ground. The only material above the surface that has been eroded The residue left behind.

Under such surface geological conditions, even if the Zerg digs downward, it is actually difficult to find a safe place in the shallow layer.

The soil here is not suitable for Zerg activities, nor is it suitable for digging holes, unless you can go very deep underground, but it will take a lot of time to dig out a space that can accommodate thousands of Zerg units.

And one thing that cannot be ignored is that the hatching of Zerg diggers requires the existence of a hatchery. In other words, even if you want to dig downwards, you must first establish a hatchery on the surface before trying to carry out operations.

A large number of these huge space insect species originally existed to serve as energy sources for the new base. They were not professional or good at digging holes.

Therefore, when the "heavy rain" moves here after landing, there is only one thing they can do - run!

With the support of vision from space, even if the weather on this planet is changeable, it is not difficult to find a safe place. However, in this process, there are still a few bugs that did not react at first and easily found a safe place. The acid rain has blended in with the land.

Zero is not an indecisive being. Since it is possible to save oneself only by digging deep underground, then just dig. After temporarily settling down again, the Zerg hatchery immediately began to be established on the spot, and several surrounding space bugs were Seeds serve as nutrients and a large number of diggers begin to produce.

No one knows when sulfuric acid rain will be generated. From space, the entire planet is turbulent. Maybe in the next second, the clouds carrying extremely acidic water vapor will move towards the Zerg temporary base, so time is extremely precious.

Fortunately, the current hatching capacity of the Zerg hatchery is no longer the same as before, and the output quantity and speed have been greatly improved.

Although the geological conditions here are special, and swallowing these sulfide sand and stones carrying strong acid substances makes the excavators quite uncomfortable, but under Zero's will, this is not a problem. The project is carried out quickly and at all costs.

In order to achieve this goal, these huge Zerg space units have also been "rebuilt" and become basic land units that can only operate on the surface. They will be responsible for clearing and strengthening the direct underground passages opened by the diggers, and at the same time also In disguise, the workload of the former is reduced.

But this means that when acid rain comes again, they will no longer have the ability to fly and escape quickly.

Fortunately, we were very lucky this time. After the diggers died one after another and were replenished in large numbers, a stable, direct underground passage was established. This also means that the first Zerg base on Planet 4 will be here. Completed here.

How the subsequent activities will unfold depends on Sass's research on the Hive Mind before he can draw a conclusion.

However, the colonization activities on Planet 4 are completely different from those of the "Moon" and Planet 2. The light resources here have been greatly weakened. Although they can still be collected and used, they are much weaker than the former, and it is very likely that they will become Shortcomings of colonial expansion.

Therefore, after settling down, Sars needs to come up with a colonization plan.

Previously, its main research goal was to solve the impact of extreme temperatures on the survival of the Zerg. There has been no result yet. However, colonizing Planet 1 is not a top priority, but the Zerg activities on Planet 4 obviously should not be postponed.

The large number of insect swarms that were originally orbiting with the rotation of Planet 4 were not in a hurry to move to the surface. Before the threat of strong acid was resolved, the insect swarms could only move underground without energy supplements from the surface. Pure resources. Mining won't last long.

Before Sass comes up with a solution, they will only sleep in orbit. Tens of thousands of Zerg units gather together, like a silent meteorite in space. No one knows that there is something hidden inside their silent bodies. What a powerful vitality.

Deep in the surface of Planet 4, a large cave space with an area of ​​more than 500 square meters successfully appeared here due to the excavation of the insect swarm regardless of the cost.

The hatchery was re-established here, and many Zerg diggers are still expanding the cave in all directions.

At this moment, they seemed to have traveled back three hundred years ago, when the ant colony was first born.

The waterproof structures on the surface are carefully constructed to prevent acidic liquids from the surface from directly entering the underground. While expanding the area of ​​underground cave structures, they also do not forget to leave load-bearing structures to avoid collapse and casualties.

In today's hatchery, not many Zerg units are born here. In addition to the existing diggers, most of the Zerg swarms that landed on Planet 4 have become nutrients for the hatchery, waiting for the day when they are needed. Reappear in the world in another form.

When it comes to the priority of colonization of Planet 1 and Planet 4, Zero unsurprisingly chose the latter. The reason is not complicated. Sasse is already at the stage of establishing a high-level solution to the Zerg's problem of surviving in harsher temperature conditions. It is not that easy to make further progress.

Although the strong acid rain faced on Planet 4 is terrifying, in Sass's knowledge system, the octopus people have done a lot of research on this. If everything goes well, it should not take too much time to achieve some results.

Everything should have gone according to plan, but before that, a surprising discovery interrupted Sasse's research.

In the process of the Diggers expanding the Zerg underground base, a small life that feeds on decomposing sulfates and severely acidifying the soil appeared in Zero's sight.
