After the mining of worker bee insects in Zhongchuan Prefecture and Jiangnan Prefecture day and night, at this moment, the energy of upgrading the worm nest from the fourth-level worm nest to the fifth-level worm nest has been accumulated.

With the high efficiency of mining speed and extremely aggressive mining methods, almost all the minerals on the surface of the land have been mined by insect swarms in Jiangnan Prefecture, which has been attacked first so far.

Only the veins hidden in the ground have not been mined by the insect swarm, and most of the ore veins hidden deep underground are thousands of meters underground, and the insect swarm still needs to carry out a stable bottom layer while digging, so the speed of exploration is far from as fast as imagined, and the huge Jiangnan Prefecture has only surveyed one-third of the area so far.

Of course, this also has to do with the fact that Lu Heng did not put all the strength of the insect swarm on it, but only sent a small number of tunnel insects and worker bee insects to dig and investigate.

And now the minerals on the land surface of the entire Jiangnan Prefecture have almost been mined, and the worker bee insects currently mined here in Zhongchuan Prefecture are completely sufficient, and these idle remaining worker bee insects are only two options, one is to wait for Lu Heng's troops to attack the new resource production area, and then they will be transported through the wormhole for mining. The other is to go underground and excavate new resource veins.

After all, on the one hand, few people can find some ore veins hidden in the underground layer of thousands of meters, and at the same time, there are some ore veins that are useless to humans, even if they are found, they are not mined, because they have no value, but these ore veins are not much different from spirit ore and cherished iron ore for the Zerg, after all, the final result is converted into energy.

Maybe there are abundant resources in Jiangnan Prefecture and Zhongchuan Prefecture, but Lu Heng will not put all the development opportunities of the Zerg on the unknown underground resources now.

Wouldn't it be more convenient to have surface resources that have already been explored than the underground resources that need to be explored.

When the Zerg is weak, they don't have so much power to find the invisible resources hidden in the ground, and after the Zerg is strong, why bother to explore it yourself, just plunder the resources that others have discovered first.

"At present, the worm nest has accumulated enough energy to upgrade to the fifth level worm nest!" Lu Heng listened to Abbather's detailed report, and a look of excitement and joy inevitably appeared on his originally calm face.

According to the almost leapfrog development of the Zerg every day, Lu Heng was not surprised that the insect nest was upgraded from level four to level five, but when he really heard and confirmed the news, there would still be a burst of excitement and joy in his heart.

After all, every upgrade of the hive will bring a qualitative leap to the Zerg, whether it is from strengthening the abilities of individual entities such as the Queen of Blades, or from the overall leap.

"We've collected enough energy to upgrade the hive while keeping all of the existing Zerg infrastructure up and running. ”

The rare Lu Heng also felt a trace of excitement and joy from the spiritual news transmitted by Abasser.

As a Zerg, the joy of the evolution of the race.

"In that case, let's upgrade the hive immediately. Lu Heng couldn't wait, and immediately issued a permission order.

After receiving Lu Heng's order, the huge fourth-level insect nest in the main base under Jiangcheng in Jiangnan Prefecture began to undergo qualitative changes at one time.

Although there are still thousands of experimental subjects in the hive, for Lu Heng at this moment, whether the evolution of the hive will make them die is not very important to Lu Heng, and at this moment, all his attention and spirit are focused on the evolved hive.

With Lu Heng's order, the energy stored in the hive began to be quickly absorbed and consumed, and at the same time, the hive, which was already a behemoth, immediately began to tremble, beating like a huge heart.

At the same time, with the beating, a crystal clear liquid seeps out from the flesh membrane of the hive.

With the increase of liquid, the entire hive began to slowly continue to expand, but the speed was not too fast, unlike the previous promotion from level 3 to level 4, this time the expansion was very slow.

And with the upgrade of the hive, Lu Heng suddenly discovered that Abbather and the rest of the brain worms suddenly fell into a forced slumber, and his spiritual energy as the master also began to slowly expand, a change that could be clearly perceived.

With the continuous upgrading of the hive, his spiritual energy has become more and more powerful, originally his spiritual energy could only control almost two-thirds of Jiangcheng without the help of swarm units, but now his spiritual spiritual energy can perfectly cover the entire Jiangcheng, and it is still expanding.

But this is not what Lu Heng pays the most attention to, what shocks him the most is that with the evolution of the insect hive, he feels the existence of the entire insect swarm, not a simple number or something, but a kind of collective similar to spiritual will.

From the units such as the Velociraptor at the bottom level, and then the Blade Queen, Brain Worm, and Hive at the top level, the pyramid-like structure finally converges into a huge whole.

And with the expansion and evolution of the hive, countless spiritual data gradually appeared in Lu Heng's mind, about the sleeping data memories stored in the Zerg genes.

In the previous evolution of the hive, these memories were stored in the hive, and then Abbather was responsible for sorting them out and passing them on to Lu Heng, but now they appeared directly in Lu Heng's mind.

"The evolution of life genes, higher-level gene sequences, and more and more complete civilization systems. ”

Lu Heng closed his eyes and began to pay attention to the latest Zerg information that kept appearing in his mind, even with Lu Heng's current huge spiritual energy, it still took a long time to fully understand it.

By the time he had observed all the data, the hive had already completed its evolution, but it could not be said that it had evolved to the so-called fifth level, because it was equivalent to an overall ascension, leaving the novice village to complete the novice mission.

"Juggernaut, the Race is on standby, awaiting your latest instructions. ”

As Lu Heng came back to his senses from checking the data, Abbather, who had already woken up, said in Lu Heng's mind.

Without immediately responding to Abbather's words, Lu Heng looked at the hive in front of him, it did not expand much in terms of area, but what changed was the entire race, as for those experimental subjects in the hive chamber, as for Lu Heng's expectations, about one-third of them died because of the evolution of the hive.

However, Lu Heng didn't care too much about this, anyway, new experimental subjects would be transported in every day, and he spent so much energy to put them into the evolutionary world as Abasser's experimental subjects, and there was no breakthrough in them, even if they were all dead, Lu Heng would not have the slightest emotional fluctuations.
