The Zerg units hatched by the level 7 main nest are all level 13 (the beginning of the Heavenly Order), and the existing Zerg units that have not reached level 13 can reach level 13 after the modulation of the main nest, and consume 30% to 50% of the resources required to hatch such units, depending on the current level.

Energy infusion will continue to provide Zerg units with physical and psionic enhancements, but due to the large amount of energy required for advancement after Zerg units level 13, energy infusion can no longer ensure that Zerg units can advance, and the main promotion methods for Zerg combat units are Fight and Devour.

In addition, due to the reinforcement materials, the main nest is temporarily unable to provide reinforcement for the Zerg Lord, and the promotion of the Zerg Lord can only rely on himself. However, the Zerg Lord can still receive a certain amount of Life Essence to add to his strength.

Qin Fan discovered a rule, when the strength of the Zerg units reached a certain level, the direct boost that the main nest could provide them became less and less, and instead played a supporting role.

Just like when the main nest was promoted to level 6, all Zerg combat units were unlocked level 13 barriers.

Before the main nest is level 6, even if the Zerg unit devours more flesh and blood, it is difficult to break through level 13, they store the excess energy they devour in their bodies, once the genes are no longer restricted, then their strength may increase several times in an instant, and the level will be promoted several levels.

However, there is an exception, this time the Zerg defense units have been greatly improved, such as the destructive power of the spore battery and the green thorn vertebrae has been doubled, but there are gains and losses, the size and weight of the two defense units have become larger, and most of the mobility has been lost, which also means that the spore battery will no longer be able to participate in the Zerg assault battle, otherwise when the spore battery is arranged, the daylily will be cold.

Moreover, the Zerg pursues attacking, attacking and attacking, if it is the turn to use the Spore Turret as an offensive unit in the future, it means that the enemy faced by the Zerg is either evenly matched, or stronger than the Zerg, and at that time, the Spore Turret alone will not necessarily have much success.

Therefore, after the Zerg completely occupied the Demon Soul Forbidden Land, Qin Fan asked all the generals to actively reflect, especially the young Zhuang faction such as Huo Quzhi, with the gradual improvement of the combat arms of the Zerg, especially the emergence of the air combat arms, more attention should be paid to the coordinated operations between the various arms, rather than simply relying on a certain combat unit to win.

Although the Zerg have always liked to use the Bug Sea tactic, if you can match the troops reasonably so that the Zerg can do less damage, but can achieve the same effect, why not?

In the future, the enemies faced by the Zerg will become stronger and stronger, and perhaps the number of some enemies is not less than that of the Zerg itself, and the Zerg cannot always rush to exchange their lives for their lives.

……

The level 7 main nest can modulate 50 million Zerg units per day, and it took half a month to complete all the concoctions.

During this period, the Zerg has been fighting violently, and a considerable number of other low-level brood hatching units also need to be debugged, which is why the progress is so slow.

Taking advantage of the fact that the resources are still sufficient, Qin Fan ordered the hatching of 30 level 6 insect nests, so that the Zerg's ability to fight further strengthens them.

But what made Qin Fan a little helpless was that due to the limitation of the substance of space crystallization, there was only one level 7 main nest, and the other thirty level 6 insect nests could not hatch level 13 combat units, and the units they hatched also needed to be modulated by level 7 main nests, and the efficiency of the rioters was virtually reduced by a large margin.

There are 500 units of space crystals left, and there are still 500 units left to gather the resources to upgrade a level 6 insect nest, but even if the resources are enough now, Qin Fan will not hatch immediately, don't forget that hatching pit worms also requires space crystals, and at the moment when the promotion of the main nest was completed, he ordered to hatch 10 pit worms.

The wormhole is too important for the current Zerg, the battlefield of the Zerg in the human world spans tens of thousands of kilometers, if you only rely on the strength of your feet, the time spent just to travel is enough.

As for the new ability space channel of the hive, it also needs to consume 50 units of space crystals, which is actually equivalent to integrating the ability of the pit worm into the mother nest, but the size of the mother nest is too large, and the resources required for hatching are also large, so it is not cost-effective to use it as a space channel alone at this time.

On top of that, the brood can't move, and the pit worms, with the help of the Zerg, can temporarily close the wormhole and move to other places.

If there is enough space crystallization in the future, Qin Fan still hopes that all the Zerg brood nests can have the ability of spatial channels, which can allow the newly hatched combat units to directly teleport to the corresponding area, and can truly link the entire insect swarm together.

Of course, that is for the future, there is no perfect strategy in the world, only to adapt to its own current situation, is the best.

In half a month, the Zerg had all completed the replacement, and Qin Fan had also received the statistical report of the main nest.

At present, there are 10,000 Zerg combat units at level 15, 40 million at level 14, and nearly 700 million at level 13. The strength of the Zerg has shown an explosive increase in the past half a month, and even Qin Fan himself gasped, he didn't know who else in this world could stop the Zerg!

If he had this strength in the first place, he wouldn't have cowered when he entered the eighth layer of the Demon Soul Forbidden Land.

However, don't look at such a big increase, its consumption is equally terrifying, and the resource reserves of the Zerg have been directly reduced by 90%, almost returning to the pre-liberation period overnight.

……

Spreading out the huge map on the table, Qin Fan pondered for a long time, a large part of the map was still blank, and only a small area was marked with some images and words.

After a while, he drew three red crosses on the map, raised his head and glanced around at the generals, and said in a deep voice: "I hope you can solve these three places within a month, and I don't want to hear excuses at that time." ”

"Respect the Lord's orders!" All the generals stood up neatly at this moment and said loudly.

Qin Fan nodded: "General Bai Qi, this month you serve as the commander-in-chief of the human battlefield, and a month later, when I leave the customs, what I want to see is a land without any resistance, even if it is a scorched earth......"

Qin Fan's figure gradually disappeared outside the big tent, but the ethereal voice still floated in the hearts of the generals.

In just one month, it is even more difficult to take an area larger than the original Kaslo Empire and the Langya Empire combined, but the generals are full of fighting spirit.

The modulated insect swarm, like an updated shotgun, has so many killer features, as long as it is reasonably arranged, it is not without opportunities.

How to deal with the three major empires of the Western Continent, Bai Qi has already had a draft, and the upgrade of the main nest is, in his opinion, just the icing on the cake for the offensive of the insect swarm, and the request of the master is actually not too much at all.

He stood on the main podium and shouted, "All the generals obey the order!" On the battle line of the Tianshi Dynasty, the Queen of Blades is the main general, leading 100 million troops; On the front of the Burning Empire, Li Mu was the main general, leading 50 million troops; On the front line of the Pharmacist Alliance, I personally served as the main general, leading 100 million troops; As for Huo Quai, he is in charge of attacking the Nanban tribe, although there is no time limit for the destruction of the Nanban tribe, but I hope you can give the master a surprise! ……”

"Next, we will discuss the specific details of the operation......"

Soon after, all the generals confidently took the order, and in the following day, the swarm moved frequently, and the legions of the various fronts began to assemble.

The three empires of the Western Continent have not yet realized that the flames of war that have been quiet for a while will once again ignite their land.
