In the underground shelter, in Chen Zheng's small room, the dim light illuminates this small space.

Xiao Xiao was sleeping soundly on the edge of the bed, and he didn't know what kind of sweet dreams his electronic brain was having.

Today, Chen Zheng left other work to play with it for a whole day, and it is inevitable that he will feel tired now after a whole day of excitement.

It is easy to be content with a simple-minded child, but it does not know the difficulties that Chen Zheng and them are currently facing.

The loss rate of the metal deposit fleet is more than 50%, the newly developed mine sites are destroyed one after another, and the insect base is getting more and more...... Under the advantages of the other, Chen Zheng's sphere of influence was gradually compressed to the limit.

If any of the mines have problems, they won't even be able to build kinetic bombs!

Thousands of Wyverns to deal with every day, including new and difficult units such as Devourers, Flying Serpents, Missile Beetle Matrix, and more......

And Chen Zheng only relied on various air defense facilities and six Viking fighters.

Chen Zheng opened his personal terminal and flipped through the newly appeared unit picture tag......

Devourer, a flying creature that is as gigantic as an aerial tanker. Its wings are transparent and have a hard shell...... On top of that, it has a mouth large enough to swallow a wyvern directly.

The Devourer flies slowly and does not have any means of long-range attacks. However, this latest unit is a nightmare for all ground units - they will swallow the wyvern around them at any time, and then sprinkle the entire wyvern into super acid...... It's simply the Zerg version of a carpet bomber!

And it is precisely because of the appearance of this unit that it has broken the previous uniformity, its carapace is very thick, its body is large, and it can withstand dozens of electromagnetic cannons and continue to fight.

But even then, in the face of powerful Viking fighters, this unit with no resistance was only slaughtered...... But the bomber escort team was really difficult to deal with.

In addition to the thousands of wyverns guarding the Devourers, the flying snakes hidden in the wyverns are the most headache - they will spit out extremely corrosive insect clouds, even if the reinforced Viking fighters rush into the insect cloud, it will be corroded and disintegrated in the air in no more than 30 seconds!

Chen Zheng had seen such a thing happen once, a Viking team's drone greedy attack did not dodge in advance, and as a result, it became the first battle loss under the mouth of the flying snake......

In fact, from another point of view, insect clouds are not terrible. It flies very slowly, so to speak, almost immobile, and it doesn't last long - the little bugs that make up the fog can't stay high in the air for too long, and it only takes about ten minutes for the little bugs to fall one after another.

When the Wyvern guards the Flying Snake and the Devourer, as long as you kill the Flying Snake from a distance, and then rush into the Wyvern group to directly dismember the Devourer, then the attack will basically be defused.

However, the bug soon added a new unit: the Missile Beetle Mother.

A missile beetle is a car-sized bug that has a short survival time and can fly at Mach 2 speeds. Originally, they appeared as a defense facility for the Zerg base, and every time they attacked the Zerg base, the first thing they had to face was these self-exploding beetles that flew extremely fast.

However, due to their short existence time and their speed is not as fast as Viking drones, their appearance did not cause much trouble for Chen Zheng's Viking fighters at first.

However, with the advent of a parent body capable of carrying a missile beetle...... Everything has changed.

It was a massive sphere the size of a football field, covered with dense honeycomb-like openings, filled with extremely fast missile beetles...... And the most unacceptable thing is that it can continue to produce missile beetles!!

It stands to reason that such a huge unit should be slow and have little self-defense...... Surprisingly, the parent missile beetle was still flying fast in a straight line - at least faster than the Devourer.

At the same time, the missile beetle mother actually has its own shield!

Although it is far less powerful than the shields of the wormman and the mother worm, even so, under the cover of the missile beetle, the worm mist, and the endless wyvern, these three huge flying units with complementary abilities become extremely difficult to entangle.

It's not that it's completely impossible to destroy these big things, but all the power Chen Zheng and them use is too limited, and everyone in the base has already been investigated, and there are very few people who can react quickly enough to effectively operate Viking fighters to fight......

Flying is never easy, not to mention that the most girls in the base are girls who have never been exposed to flight simulation games.

In fact, in the final analysis, the reason is still that sentence: lack of manpower.

Not much, as long as Chen Zheng is given 10 more talented drone operators, he can start seeking expansion while holding on to his existing base.

Give him 20 more, and he'll be guaranteed to intercept the bugs' attacks halfway through!

If he is given 50 operators, Chen Zheng can guarantee that the Zerg will not be able to open a single sub-base!

However, the reality is so cruel, Chen Zheng's warehouse is empty of more than a hundred Viking drones, but there is no personnel who can operate them.

And that's not all.

There is also a serious shortage of other personnel in the base...... Even the most important monitoring personnel barely managed to maintain monitoring of the base and several important mines in three shifts.

However, no matter how short of manpower there is, Chen Zheng did not agree to involve the miners...... Letting them join various departments is simply drinking water to quench their thirst.

Even the proposal to make them combatants was dismissed, and Chen Zheng could not let go of it.

Apart from the miners, there is no other way to replenish personnel in the base.

So, the priority of that plan has been raised again.

That's right...... It's the Tidegate Project.

Since Her Royal Highness the princess left, Chen Zheng began to activate the Tide Gate Project. However, the complexity of the tidal gate is too high, and the demand for processing accuracy, materials and various rare metals is too great, especially for the demand for zero crystals, which once appeared to be scarce due to the relationship between operations......

Fortunately, a small number of zero crystals can be found in the downed missile beetle matrix, and it is precisely because of its replenishment that Lao Xia's tidal gate project can continue.

And tomorrow will be the day of the first tidal gate experiment.

All the parameters have been calculated many times, and all the operating processes have been rehearsed countless times......

Chen Zheng touched his little head, then shrunk into the quilt and turned off the lamp.
