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

Xiaoxiao lying on the edge of the bed and sleeping soundly, and she didn't know what kind of dream her electronic brain was doing.

Today, Chen Zheng left other jobs and played with him for a whole day. After being excited for a whole day, he was inevitably tired now.

The simple-minded little girl is easily content, but it does not know the difficulties Chen Zheng and the others are currently facing.

The loss rate of metal mine transport teams exceeded 50%, newly developed mine sites were destroyed one after another, and the more insect bases were hit... As one went up and down, Chen Zheng and his sphere of influence were gradually compressed to the limit.

If there is any problem with the mine, they will not even be able to create kinetic energy bombs!

We have to deal with thousands of flying dragons every day, including newly emerged difficult units such as Devourers, Flying Snakes, Missile Beetles, etc.

All Chen Zheng and his team could rely on were various air defense facilities and six Viking fighters.

Chen Zheng opened his personal terminal and opened the recently emerging unit picture sign...

The Devourer is a flying creature that is huge as a tanker in the air. Its wings are transparent and hard shells... and most importantly, it has a mouth that is so huge that it can swallow a flying dragon directly.

The Devourer's flight speed is slow and there is no long-range attack method. However, this latest unit is a nightmare for all ground units - they will swallow the flying dragon around them at any time, and then turn the entire flying dragon into super acid and sprinkle it on the ground... It's simply the Zerg version of a carpet bomber!

It is precisely because of the emergence of this unit that it broke the uniformity of the past. Its shell is very thick and its body is very large. It can be hit by dozens of electromagnetic cannons to continue fighting.

But even so, when facing the powerful Viking fighter jets, such units without resistance were only massacred... But the escort team of bombers was really difficult to deal with.

In addition to thousands of flying dragons, the flying snakes hidden among the flying dragons are the most troublesome - they will spit out extremely corrosive insect clouds. Even if the Viking fighter with steel and iron bones rushed into the insect cloud, it will be corroded and disintegrated in the air in less than 30 seconds!

Chen Zheng had seen such a thing happen once. A Viking Squad's drone greedy for attacks and did not dodge in advance, and it turned out to be the first battle loss under the mouth of the flying snake...

In fact, to put it another way, the insect cloud is not terrible. Its flight speed is very slow, it can be said to be almost impossible to move, and it does not last long - the small insects that make up fog cannot stay at high altitude for too long, and in about ten minutes, the small insects will fall down one after another.

When the flying dragon guards the flying snake and the devourer attack, just kill the flying snake from a distance, and then rush into the flying dragon group and dismember the devourer directly. Then this attack will basically be resolved.

However, the bug soon added another unit: the missile beetle mother.

Missile beetles are car-sized bugs that have a short survival time and can fly at a speed of Mach 2. Originally, they appeared as defense facilities for Zerg bases. Every time they attack Zerg bases, the first thing they have to face are these self-destructive beetles with extremely fast flying speeds.

However, because they existed for a short time and were not as fast as Viking drones, their initial appearance did not cause much trouble to Chen Zheng's Viking fighter jets.

However, with the emergence of the mother body that can carry missile beetles... everything has changed.

It was a huge sphere as big as a football field. Its surface was covered with dense honeycomb-shaped openings, and it was loaded with missile beetles with extremely fast flight speeds... and the most unacceptable thing is that it can actually continue to produce missile beetles!!

Logically speaking, such a huge unit should have a slow flight speed and no self-defense ability... But surprisingly, this missile beetle mother flies very fast in a straight line - at least faster than the Devourer.

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

Although its strength is far inferior to the shields of insects and mother insects, even so, under the cover of missile beetles, insect fog and endless flying dragons, these three huge flying units with complementary abilities become extremely difficult to deal with.

It’s not that it is impossible to eliminate these big things at all, but the power used by Chen Zheng and others is too limited, and everyone in the base has already checked it, and the reaction is fast enough to effectively control Viking fighters...

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

In fact, the final reason is still the same sentence: insufficient manpower.

No need to do it. Just give Chen Zheng 10 talented drone operators, and he can start to expand while defending his existing base.

Give him another 20, and he can guarantee to intercept the bugs' attacks halfway!

If Chen Zheng is given 50 operators, he will be sure that even the Zerg can't open a branch base!

However, the reality is so cruel. Chen Zheng had more than 100 Viking drones in his warehouse, but he was struggling to have no personnel who could operate them.

Not only that.

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

However, even if there is no manpower, Chen Zheng did not agree to let the miners participate... Letting them join various departments is simply a poison to quench thirst.

Even the proposal to make them fighters was rejected, and Chen Zheng must not let go.

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

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

That's right...it's the Tide Gate Plan.

Since His Royal Highness left, Chen Zheng began to launch the Tide Gate Project. However, the Tide Gate is too complex and the demand for processing accuracy, materials and various rare metals is too great, especially for zero crystals. Due to the combat relationship, there was a shortage of zero crystals...

Fortunately, a small amount of zero crystals can be found in the downed missile beetle mother body. It is precisely because of its supplement that Lao Xia's tide gate project can continue.

And tomorrow is the day of the first Tide Gate experiment.

All parameters have been calculated many times, and all operation processes have also undergone countless previews...
