Qin Feng continued his search forward and soon encountered a monster. He commanded his Red Alert soldiers to kill the monster, finding a plant-type treasure in the cave. Qin Feng had a thorough understanding of this area: he could not use his own strength here. Cultivators were unable to unleash their abilities in this space, and the monsters in this region were known for their robust physiques, yet they were no match for his super Red Alert soldiers.
All the treasures obtained were plant-type. Qin Feng did not know the extent of this area; he could only explore as he went.
After encountering several more monsters in succession, Qin Feng had a rough estimate of the monster population in this space.
The monster density in this area was much higher than in the previous desert region, implying that there were also many treasures here. However, he could not obtain them all at once and had to search one by one, finding the monsters to get the treasures.
This was a significant difference from the previous space.
In the previous space, monsters would actively emerge at night. After they were killed, the treasures would appear in their place during the day. This space was different; monsters did not roam around at night but stayed near their caves. Therefore, although there were many monsters in this space, he could not kill them all in a short period. He had to find them one by one, which would greatly waste his time.
The Heavenly Round and Square Chessboard had entered its cooldown state, preventing Qin Feng from finding monsters through its guidance. He could only blindly search this space. The only way to save time was to control his over 300 super Red Alert soldiers, scattering them throughout the area to search slowly.
As long as they encountered and killed a monster, they were to bring back the treasure from the cave.
However, doing so would greatly drain his mental energy. Concentrating his Red Alert army around him allowed for effortless command. Due to shared vision and battlefield awareness, he could conserve his mental energy to the maximum extent while controlling over 300 super Red Alert soldiers.
This was because the enemies they faced were singular or few, within a fixed range, allowing him to save considerable energy. But if these super Red Alert soldiers were scattered across various corners, he would have to focus his mental energy intensely on each soldier. Their perspectives would not be shared, and their objectives would all be different. If one super Red Alert soldier encountered a monster, he would command that soldier to fight, while another soldier might still be searching.
Even with his ability to multitask, despite reaching the Nascent Soul stage and having tens of thousands of mental energy, he could not persist for long.
If his mental energy was within a small radius, commanding ten thousand Red Alert soldiers simultaneously would be more than enough. However, on a large-scale battlefield, he might be willing but unable.
Nevertheless, leading the 300 super Red Alert soldiers to aimlessly search for monsters was a wasteful endeavor. A single Red Alert soldier could easily defeat these monsters; there was no need to waste his combat power in such a manner.
Therefore, even with the significant strain on his mental energy, he had to try.
Qin Feng had his super Red Alert soldiers spread out to search for monsters. When his mental energy was about to give out, he could simply recall them. This also served as a test to see how many super Red Alert soldiers he could command on a large-scale battlefield.
Thus, Qin Feng entered the underground fortress and then commanded the 300 super Red Alert soldiers to scatter around. Each soldier was positioned differently, moving rapidly in all directions from Qin Feng as the center. Upon discovering a monster, they would mercilessly kill it, place the plant-type treasure from the monster's cave into a pre-prepared flowerpot, and then continue their search. When they encountered another monster, they would place the treasure on the ground and continue fighting.
After an unknown period, Qin Feng felt his mental energy beginning to falter. He checked the time; 10 hours had passed.
Qin Feng opened his attribute panel.
[Name]: Qin Feng
[Level]: 166 (166/9999)
[Reputation]: 28
[Strength]: 34000
[Agility]: 48000
[Constitution]: 32000
[Mental Energy]: 3200/30000
[Talent]: SSS-Class "Red Alert Domain"
[Skills]: None
[Combat Power]: 4000
[Gold]: 8205986
His mental energy had been depleted by almost ninety percent, leaving him with very little.
While he still had the ability to control these super Red Alert soldiers, Qin Feng hurriedly commanded them to gather towards him with the harvested treasures.
In these 10 hours, Qin Feng had reaped considerable rewards; almost every super soldier returned carrying three treasures.
This kind of combat consumed a great deal of Qin Feng's mental energy, but the rewards were also substantial.
If he had to search for monsters one by one, it would have taken him at least a month to achieve such a harvest and kill so many monsters. The sky had already darkened. Qin Feng quickly sat down cross-legged to recover his mental energy.
Although he could not cultivate in this space, he could still recover his mental energy. Mental energy was merely a form of his vitality, not reliant on the assistance of spiritual energy from heaven and earth. He only needed to purchase some mental energy recovery pills from the shop.
Having used them before, Qin Feng purchased more energy pills. After taking them, his energy quickly recovered by half.
However, it would take a long time to restore his mental energy to its peak state.
Mental energy was different from his combat power and had no relation to his cultivation. To recover his mental energy, he could only rely on rest. The assistance of medicine was also very limited. Energy pills could restore half of his energy but not to its peak. Recovering mental energy through rest was very slow. Although it was recovering every moment, Qin Feng calculated that it would take at least several days to return to its peak state. He could not stay put and recover for days; he had to keep fighting to prevent the curse above his head from acting up.
Therefore, after a night of rest, Qin Feng's mental energy was at about 60% of its peak.
He had no choice but to continue fighting.
He then left the fortress, purchased a helicopter, and piloted it into the distance, commanding his super Red Alert army to quickly follow his pace.
His intention in doing so was to relocate his fortress and, from that new location, have these super Red Alert soldiers spread out to kill monsters, as the monsters in this area had been mostly eliminated by him.
Continuing to stay in the same place would yield very little. He needed to move to a new location and start anew, all to maximize his benefits.
