Latest website: The fourth class that makes up the sixth class will automatically be promoted to the fifth class after it is formed, because the fifth class is naturally linked to the sixth class and affects the whole body. This is unmatched by the fourth class Powerful advantage.

Although the Zerg is still the fourth tier in terms of classification, their territory has reached the sixth tier, all because they are too special.

It is difficult for countries and forces in the normal world to control such a huge scope. Their administrative capacity cannot meet the requirements, which will inevitably lead to splits. Therefore, there will be a fifth and sixth class division.

But the Zerg will not split, so they will not have any problems because of the large territory.

However, although a single sixth tier of Zerg can cope with it, the plural sixth tiers are difficult to fight. The enemy's resources are much higher than the Zerg, and the number is much higher than that of the Zerg. In terms of using the spiritual realm, the opponent is better than the Zerg. They are more in-depth and know how to use tactics.

For example, deliberately lure the Zerg biota into the spiritual realm, use the characteristics of the spiritual realm to eliminate the Zerg biota, or mislead the Zerg biota to lure them to the dedicated destruction of the spirits, and so on.

However, the Zergs are not without their own advantages. They reproduce very fast, which allows them to maintain a basic line of combat power, which adds considerable difficulty to the advancement of the two sixth-tier coalition forces. .

In order to gain a stronger force against the coalition forces of the two sixth tiers, the Zerg began to develop genes for super-large organisms.

Zerg has always faced a problem, that is, the larger the size of the creature, the slower the reproduction speed.

The fundamental reason lies in genes. The longer the gene chain of a cell, the longer the process of untwisting, transcription, and division of the cell will inevitably be. On a macro scale, the growth rate will slow down.

The larger the size of the organism, the more complex its structure, which also means the longer the gene chain.

Therefore, the larger the size of the creature, the slower the growth rate. Such a super-large creature like the Zerg conceived, it may take enough time for the enemy to destroy the Zerg many times.

This is the limitation of genes. Zerg has studied genes for so long and finally touched this edge, but they don't know how to solve them. What else do they have besides genes? It can only be the spiritual realm.

Through sacrifices, they obtained a solution to the problem from the spirit deity. Super-large organisms do not have to directly reproduce the entire organism. All the tissues and organs of the super-large organisms can be regarded as independent organisms, and the Zerg species reproduces. These biological tissues, and then combine these biological tissues, you can get the kind of super-large creatures they conceived.

According to this line of thinking, the Zerg’s super-large creatures were successfully reproduced in a short time and were named ‘Leviathan’ by the Zerg.

Leviathan possessed a strong combat capability, and was then dominated and dispatched to an important strategic node on the front line, containing the offensive of the two sixth-tier coalition forces and beginning to enter a stalemate.

Because of the addition of Leviathan, the super-large creatures, the fighting power on both sides has entered the same situation, but the situation of the Zerg is special, because the two sixth-tier fighters are a little less, but the Zerg can die as much as possible. Strictly speaking, the Zerg has gained the advantage of war.

The stalemate lasted for hundreds of years, and the two sixth classes finally showed a slight exhaustion. The Zerg began to slowly push back, and the territory captured by the coalition forces was gradually recovered by the Zerg.

However, the coalition forces have long been prepared. The Zerg can obtain very little biomass, and the regained planet is a barren ruin, not to mention animals, not even plants.

It didn't take long for the Zergs to stop their expansion after attacking some of the fifths of the two sixths.

A total of more than sixty sixth stratums that have not yet fought have sent a warning to the Zerg that if they don’t stop their expansion immediately, they will join forces to attack the Zerg.

Needless to say, this is a force that the Zerg cannot contend, and even if the number of Leviathans is increased several thousand times, it is far from enough to fight against it.

These sixth classes will have this reaction. It is the diplomatic result of the continuous lobbying of the two sixth classes that were at war with the Zerg. There is also a credit for the Zerg. They madly swallowed all organic matter and succeeded in letting others. Failure to engage with the sixth class is seen as a serious threat.

After all, after being defeated by other countries and forces, at least the race can be left behind. Things like subjugation and extinction rarely happen, because you can't get anything by doing so, and the Zerg who devours all biomass is in the door world. It's like a different kind.

Those sixth class who have sent warnings to the Zerg require the Zerg to make an agreement with them, with the guarantee of supremacy. They will never continue to expand in the door world. On the contrary, they will never attack what the Zerg controls. territory.

If the Zerg refuses, then they will consider providing material assistance to the two sixth classes that are at war with the Zerg.

The Zerg has no choice. Their bloodthirsty can only stand aside in front of the existence of the race. Moreover, this agreement is not unacceptable. As long as the strength of the entire Zerg is developed to the seventh-order supreme level after signing, the so-called agreement You don’t have to comply anymore.

The Zerg who reached the sixth stratum had no doubts about whether they could enter the seventh stratum. At this time, the Zerg had no knowledge of the seventh stratum.

They know that the seventh class is stronger than the sixth class, but they don't know how strong it is.

On the one hand, because things related to the seventh class are very rare, and many are regarded as myths and legends, on the other hand, the Zerg eats when they see people. As a result, the Zerg has no concept of the seventh class.

The Zerg keeps hoarding numbers, especially Leviathan. Leviathan's strength has passed the test of war.

By inquiring about the number of the sixth stratum in the door world from the two neighboring sixth stratums that have relaxed their vigilance, and using this number of the sixth stratum as military imaginary enemies, the Zerg continues to accumulate military strength.

When they continue to crush all the combined military forces of the sixth stratum, it is when they violate the agreement.

As for the seventh class as a guarantee? Could it be that they can defeat the combined forces of all the sixth classes in the entire door world?

Because of the Never Expansion Agreement~lightnovelpub.net~ Although the Zerg is bloodthirsty and brutal, the sixth class has relaxed a lot on them, which provides a lot of convenience for the Zerg to obtain information.

The Zergs mainly acquire the actual military power of each sixth class. They are very careful in this regard. After all, this is directly related to the survival of the race. After a violation of the agreement, if they lose, the sixth class in the door world will no longer be stupid. To conclude a new agreement with them.

So we must be cautious.

After a long time of continuing the power in this way, it was confirmed that the military power could crush all the sixth stratum in the door world. After a long period of savings, the Zerg finally launched a new round of war.

The first to bear the brunt is the two adjacent sixth classes. The huge number of Zerg biota swamped the two sixth classes that were inextricably fought with them at first, like a flood, and the other sixth classes are the same. There is no way to fight back, and the planets are reduced to the den of the Zerg race.

Then... the swarms of worms that raged outside the Zerg territory were gone.
