One month after the first entrance to the cave was found, Lin Feng, his people, and some hunters found two other entrances.
Lin Qiao was right. Those creatures would move to another area once they ate all animals in one.
Currently, two new entrances were found in the northeast and the southeast to the first one, both ten miles away from the first entrances. One day, an entrance like that might show up near All Beings Base.
Lin Qiao was paying a big price to gather information about those creatures. During the past month, three hunters groups had fallen in the cave. Added with the soldiers who were brought there by Lin Feng, hundreds of people had died in the cave so far.
Later on, Lin Qiao sent Yun Meng and the other zombies. But still, they suffered attacks and fell back. Those creatures didn't eat zombies, but responded intensely when zombies invaded their territories.
Thankfully, zombies were strong. It was impossible to kill zombies without hurting their heads. Yet, the level-six zombies and five zombie leaders who followed Yun Meng into the cave were all covered in wounds when they came out.
Nan Jin, the level-six zombie, had one arm cut off in the cave.
The injured zombies wouldn't die, but they wouldn't heal either unless they ate human flesh and drank human blood. The zombies in All Beings Base didn't eat people, so their injuries would stay on them.
Lin Qiao had no solution to that. Mo Yan's zombie lady would be able to heal those injured zombies, but Lin Qiao couldn't enter the space to bring her out at the moment.
All she could do at the moment was to use the lake water to keep those injuries from worsening. The lake water could heal injuries for human beings, but not for zombies. It was able to keep the zombies' injuries from worsening though. To heal those zombies, Lin Qiao needed to dive into the lake to borrow the energy there.
Those creatures were weird. Yun Meng turned herself invisible, but they could still sense her. They didn't have eyes, so they 'looked' with their other organs.
As a high-leveled zombie, Yun Meng reacted fast enough to run out of the cave safely. It was still dangerous though as three level-seven gorillas chased her out of the cave.
Fortunately, those creatures seemed to be scared of sunlight. They stopped attacking once Yun Meng and the other zombies went out of the cave.
The next time, they went back into the cave with fluorescent lamps, and those creatures drew back immediately. It turned out that they weren't only afraid of the sunlight, but all strong lights.
Those underground gorillas were smart though, as they learned to destroy the lights before attacking.
By that time, Yun Meng and the other zombies had gained a vision of almost the entire cave. The ground floor was composed of a lot of tunnels. Underneath those tunnels were some large holes filled with bones from the animals that had been eaten.
All those fresh bones produced an awful odor.
Some tunnels led further downward. But, Yun Meng and the zombie zombies didn't manage to go further down before some crazy level six or seven gorillas chased them out.
Even though zombies were stronger than human beings, some lower leveled zombies still died in the cave.
Lin Qiao read the report from All Beings Base and felt that things were getting more and more serious. During the past month, All Beings Base members failed to kill even one of those underground creatures.
Those creatures were invincible. Superpower attacks could barely hurt them! Fire and ice were harmless to them, and wind blades could only leave white marks on their skins. Poisons were useless too. Those creatures had their bodies covered in virus. They could infect other animals by scratching them.
Because of that, Lin Feng, Yuan Tianxing, and Yun Meng were all suffering a headache. All they could do was to report to Lin Qiao about what happened and wait for her to come up with a solution.
After reading the report, Lin Qiao gave a long sigh. She had no good ideas right now. At last, she sent Yun Meng and a few zombie squads to blow up the three entrances and stop those creatures from coming back out temporarily.
However, the underground space was their territory. Not to mention how many other entrances they had created, blowing up the existing entrances wouldn't be able to stop them for long.
Lin Qiao wanted to go into the cave and see it for herself. So, she had no choice but to ask Wu Chengyue to go with her.
Wu Chengyue learned about those creatures from her. He felt into silence when reading about how strong and aggressive those creatures were. He carefully read the report and the other materials with a frown, then agreed to Lin Qiao's request.
"What are they? Where are they from?" He asked.
Lin Qiao wrote on the paper—'They are afraid of the sunlight, so I think they've been living underground the whole time. They are large and strong. I don't think the surface layer of the earth was where they lived before."
Wu Chengyue immediately figured out her meaning. "Are you saying that… they're creatures from the earth's core?"
Lin Qiao nodded. Realizing that he couldn't see her nodding, she knocked the table with the pen and then wrote—'The underground world always existed. Yun Meng said that all the tunnels they saw are new."
Those creatures should not have showed up on the surface of the earth.
Wu Chengyue understood what she meant. He knitted his brows into a deeper frown, saying, "From the earth core? Why don't they stay where they were? Why would they come up to the surface?"
The most important thing now wasn't why they came out of the earth core, but to figure out their weakness. Based on what happened during the past month, those creatures didn't show up with good intentions. All Beings Base might not be the only base in danger. If no one tried to stop those creatures. Sea City Base would be threatened as well. After all, it was not far away from the cave.
"They are afraid of the sunlight, but not fire. What on earth are they really afraid of?" Wu Chengyue was thinking.
Lin Qiao thought for a moment, then wrote—'Ultraviolet rays maybe, or any other things contained in the sunlight.'
Wu Chengyue nodded slightly and said, "Perhaps. Let's lure them out of the cave and see what the sunlight will do to them."
'I've told them to try that,' Lin Qiao wrote, 'They are smart and sneaky. They won't come out during the daytime.'
Wu Chengyue thought briefly and said, "Then we have to go there and see for ourselves, to find out exactly how strong they are."
Lin Qiao narrowed her eyes to observe the energy inside Wu Chengyue's body. The light of his energy was a little dimmer than before. It barely affected him though.
