The unprecedented beast tide had caused considerable damage to Base 2, with almost half of the command building paralyzed and most of the auxiliary equipment destroyed. Fortunately, the mastermind was not affected, but the amount of reconstruction work is still huge, and many of the equipment are left over from the previous Federation, and there is no way to repair it after it breaks. These devices are not as indispensable as the main brain, but without them, work is less smooth.

The dormitory area was also badly damaged, first half of it was blown up by the giant thorns, and then it was washed into the interior by the beasts, turning it into a battlefield, with the result that two-thirds of the area was destroyed. The large spines that exploded at the rear had a slight impact on the production area, destroying several refining furnaces.

The loss of personnel is not large, mainly because the one-time loss of nearly 100 officers in the command building is somewhat painful, and secondly, the loss of more than 200 personnel under construction in the underground space. Other than that, the rest of the combat casualties are in the single digits.

The traditional way of attacking the beast tide is no longer a big threat to the base, but the speed at which the beast tide evolves is astounding, and almost every time a new class of troops appears in the big beast tide. Some of the new classes are flashy, such as the balloon war beasts that appeared this time, which seem to have little effect other than projection propaganda.

But there are also classes with infinite potential and great power, such as the first appearance of the Thorn Behemoth, which fires spikes with infinite power and explosive ability, and is completely a catapult version of a ground missile. If it weren't for Chu Jungui's deployment of the Alpha Cannon in the base, and even the cheating particle main gun, these two giant beasts alone would have been able to bulldoze the base.

In addition to the material and human losses, plans to expand the base into underground space have been put on hold.

What worries Chu Jungui even more is the tactical coordination ability embodied by the war beast. This makes the beast tide more like an army, and it is well-trained and fearless to death.

To be honest, Chu Jungui didn't want to fight such an enemy, and no one wanted to. However, there is no way to avoid it on Planet 4, there is no way to escape, there is only to fight.

Chu Jungui suppressed the hidden worries, arranged the renovation work of the base first, and then led a team of commandos into the passage where the war beast came from underground and went back to investigate.

As a result, about a few hundred meters deeper, the passage was sealed. Looking at the traces of blocking, it is obvious that it was done by war beasts again. Chu Jungui tried to excavate, but after digging for several meters, the soil and stone were still firmly sealed, and he didn't know how thick the blocked road section was.

It seems that the war beast has completely sealed all the passages, and at this moment, Chu Jungui lacks large tools in his hands, so he has to retreat to the base first.

Inside and outside the base, they are scrambling to clean up the battlefield, and a large number of soldiers are rummaging through the rubble, recovering equipment that can still be used, and then cleaning up the rubble.

Fortunately, the production capacity of the base was not greatly affected, so more than 100 engineering vehicles were urgently produced, and the cleaning efficiency was greatly improved.

The beast tide is both a crisis and a resource. War beasts are the source of almost all important organic materials, and some rare materials are the only source. New war beasts always surprise people, and this time is no exception.

Not only did the two mountain-like thorn beasts provide a large amount of flesh and blood, but the thorns behind them contained a new kind of liquid. Once the spines are fired, the inside of the bottom ruptures, leaking a new bodily fluid. When the two biological liquids were mixed together, they became a powerful liquid explosive, which was twice as powerful as Chu Jungui's existing biomass explosives.

With the samples, the biologists at the base were able to produce them in large quantities. Before there was a dedicated large reactor, an organic matter editor could also be used to ensure a certain level of efficiency.

With the new explosives, the existing weapon systems almost all have to be re-studied, which can be considered a happy annoyance.

Balloon War Beasts are another surprise. These guys look somewhat similar to floating fish, and their bodies can swell several times when needed. They have a transparent hard film on their backs, which is quite high in light transmission and purity. They can produce hydrogen and helium in their bodies to float. Subdural organs emit surprisingly high heat, projecting high-brightness beams, somewhat similar to lasers.

The power of the beam projected by each balloon beast is not very high, only a few hundred watts, but the problem is that they have mastered the right direction, and they have managed to evolve an organ that can emit lasers, and they have put it into practical use.

It's just that the war beast uses the big killer weapon of the biological laser for propaganda, which is a little speechless. It's just that the Fog Clan led by Brother Dao is actually extremely intelligent, and it won't be long before they may find the correct use of the Balloon War Beast, at least the Alpha Cannon has already pointed them in the direction.

At this time, Chu Jungui couldn't help but secretly rejoice that he had killed the fog clan in the first place, otherwise it would have brought back the information of the alpha cannon, and maybe the next time Chu Jungui would have to taste the taste of the alpha cannon.

The encounter with the S-class beast tide drew Chu Jungui's attention back to Planet 4 again. The presence of the Fog Clan and War Beasts is a direct threat to the base, and their extraordinary rate of evolution puts pressure on the test subjects. However, the threat of the Outer Space Federation is also real and growing.

Chu Jungui didn't know the grand strategy of the Tang Dynasty, but he knew that he had to hold on week by week. If you can't make it, then there's nothing to do.

At this moment, Chu Jungui has a feeling of internal and external difficulties, but fortunately, the test subjects have never said that they have mood swings, and some just solve problems when they encounter them, and solve them one by one.

Chu Jungui immediately ordered the dispatch of 100 commandos to take the engineering vehicles and continue to dig along the passage blocked by the war beasts, and it was necessary to find out from which direction and how the war beasts dug into the base.

At the same time, he arranged for a group of scientists to specialize in studying the geological structure below the base, as well as the excavation methods of the war beasts. Under normal circumstances, there is the existence of Cambrian, and the base has a grasp of the underground situation within a radius of 100 kilometers, but I didn't expect that the war beast could avoid the detection of Cambrian. If you don't solve the threat from underground, I'm afraid you won't even be able to sleep.

When all the work was arranged and Chu Jungui had time to go back and sort out the data, he found a small anomaly. This time, the materials recovered from the war beast were 10% less than the normal level.

Chu Jungui searched carefully and found the reason: a large number of war beasts killed by the particle cannon basically evaporated on the spot, and no materials were left.

The subject could not laugh or cry, and could only accept the result. Just as he was about to embark on the development of a new generation of weapons, Li Xinyi rushed into his laboratory and waved his hand, "Guess what I found?"

Chu Jun returned to the palm of her hand and saw a pale black crystal. For some reason, the moment he saw this crystal, Chu Jungui suddenly felt that the cells in his whole body were vibrating slightly.
