The Bug Nest successfully evolved to the seventh tier. The worst-case scenario had not occurred, which meant there was plenty of room to maneuver.
The seventh-tier Bug Nest had changed considerably. Its overall height had increased to over 176 meters, enough to accommodate the required organs. Any taller, and it would only increase the area vulnerable to attack.
The Demon Beasts had undergone their fifth genetic evolution. Seventh-tier Demon Beasts had not yet been bred, so their exact combat strength was unknown.
As for the Leviathans, they had successfully undergone their second genetic evolution. Meanwhile, the seventh-tier Bug Nest's ultimate weapon—the Demon Flame Dragon—required 236,000 points of biological energy. This giant combat Zerg would definitely not be weak.
All the Bug Nest's organs had advanced to the seventh tier, and its maximum biological energy storage had reached 6.5 million points. Evolving to the eighth tier was completely impossible in this world.
Besides that, the Bug Nest had awakened another ability. This was a branch ability of the Worker Scorpion called the "Energy Conversion Spore Sac."
As long as it was not too far from the Bug Nest—within a range of less than a thousand kilometers—it could sacrifice a Worker Scorpion and transform it into the Zerg building known as an "Energy Conversion Spore Sac."
A single Energy Conversion Spore Sac could spread a 1.2-kilometer carpet of fungi. After absorbing biological energy on the battlefield, the carpet of fungi would transmit it to the Energy Conversion Spore Sac at its center. After compression and crystallization, it would become Life Stones.
Life Stones were special items that only the Bug Nest could absorb. Each Life Stone could be converted into 10,000 points of biological energy.
This made going to war far more convenient. There was no need to transport Demon Beasts or
