This void is formed by countless huge caves, one connected to another, extending to a distance that cannot be seen by the naked eye.

From time to time, huge stone pillars and rock walls are connected to the top of the cave, forming a stable support.

Looking at the shape and trend of this hollow, it is obviously formed by erosion of underground rivers. Due to years of erosion, the hollows become larger and larger, the terrain becomes lower and lower, and the water flows to lower places, and then these hollows are exposed.

Rob walked a distance along the erosion marks, and then heard the intense sound of water flowing.

What reflected Rob's eyes was a spacious and turbulent underground river. The river surface was more than ten meters wide, and the water flow was very fast. The water flow hit the two sides, stirring up mist in the sky.

Rob subconsciously took two steps back. When he was a metal and wood body, what he hated the most was water vapor. The damp water vapor would rust the iron and make the wood swell, causing Rob to use carbon brushes to clean the water vapor frequently. When sunlight shone into the laboratory, he would stand under the sun to dry it, just to remove the water vapor. So when he saw the water mist in the sky, his first reaction was disgust.

However, after taking two steps, he also realized that he was no longer a metal body that was afraid of water vapor.

It’s good to have water. Although Robu doesn’t like water, he still cannot do without water. His body’s activity needs to be maintained, which is inseparable from water. Moreover, various experiments and manufacturing processes are also inseparable from water.

The most important fire in the construction process can also be replaced by a magic crystal furnace, but nothing can be replaced by water. With abundant water here, it means that the laboratory can be completely built here.

After Tielle led the villagers of Tiedun Village into the cave, he cleaned up their traces, and then found a platform protruding from the ground by the underground river, and temporarily settled down at that time.

Rob has been traveling around the cave these two days. He released all the detection structures, constantly exploring the terrain, hoping to find a suitable place to build a laboratory.

The ideal terrain of Rob is best to have a wide middle and narrow cave at both ends in a solid rock formation. The terrain should be high and there is no danger of flooding. It should be well connected and connected. It will not be blocked by people in one direction and cannot escape. The terrain should be dangerous and easy to defend and difficult to attack.

He asked so much, so after two days of busyness, Rob still got nothing.

The scope of the underground cave is too large. After searching for two days, I didn’t search for many places. Instead, I found some shiny plants in many caves.

It was something like moss. In the dark environment, it would emit a faint white light. Rob named it fluorescent moss.

This kind of fluorescent moss is very wide distributed, and they can be seen in almost all caves. When they are densely populated, even if ordinary people come in, they don’t need any lighting to see the environment clearly.

"What a magical plant. Didn't the God of Harvest say that plants need air, sunlight and water to grow? There is no sunlight below the ground, so why do so many moss grow?" Tiele said in surprise.

During the exploration activities these two days, Tiel has been following Rob. After all, he is responsible for the settlement of hundreds of villagers in the entire village, and he needs to determine which place to settle down in person.

Iron Dun Village cannot go back for the time being. They are provoking top-notch people like Teddy Ross. Even if the other party will not stay in Iron Dun Village, they will be finished as soon as they pass by it occasionally. So for a long time, it is impossible for them to go back to Iron Dun Village, and maybe they will never go back again. So they must find a suitable place to settle down.

In addition to Tiel, Rob also brought Cabrit. Rob didn't dare to let him leave his sight for a long time. Although there were stable runes that bound the other party's soul in the core, even Rob himself didn't know whether it was effective. With Cabrit's knowledge, there might be some way to escape from this kind of constraint. Therefore, Rob must put the other party in his eyelids and monitor at any time.

Moreover, Rob also discovered that Cabrit's experience and knowledge made him almost a living dictionary, and almost all the questions about ancient and undead could not be difficult for him. Keep him with him and can answer his own questions at any time.

Hearing Tiel's words, Cabrit laughed: "Which harvest goddess is so stupid? Are you lying to you?"

"You..." Tiele was furious.

"This world does not need sunshine, air or even water, and this moss is just one of them. Although you don't know, the so-called Goddess of Harvest will definitely know. If she still tells you like this, what isn't she lie to you?" Cabrit did not take Tiel's anger seriously at all and continued.

Tiele pinched his fists twice. If it weren't for the fact that this thing was created by Lord Fegut, he would have punched him. Now he could only endure it and turn his head and not be as knowledgeable as the other party.

Rob didn't have the energy to pay attention to the small conflicts between them. He focused all the detection structures released. He carefully recorded the routes through which the detection structures passed, slowly forming a complex cave route map, trying to find a suitable place to settle in it.

After turning a corner, a bright light suddenly appeared in the cave in front.

After entering this range, the cave is not completely pitch black because there are fluorescent moss everywhere. However, compared with the faint fluorescence, the light of the cave in front can be considered bright.

What exactly emits light?

When they arrived at the place where the light came, they turned around and at the turn, everyone felt like they were open. Excessive light filled the vision of Robu and others, making it impossible for them to see clearly what was emitting light. After stopping for a while, after adapting to the light, Robu discovered that the entire huge cave, the walls and ground on all sides were covered with fluorescent moss. A large amount of fluorescent moss was concentrated together and emitted a light that was no less than the daytime.

Such dense fluorescent moss is unprecedented in Rob, and fluorescent moss usually only grows on the ground, because the ground is wetter than the cave walls and is more suitable for the growth of moss. There has never been a case where the cave walls are denser than the ground.

After careful observation, Rob saw something that interested him more. Whether it was the hole wall or the ground, the fluorescent moss was distributed very neatly, and the spacing between them was almost the same. This regular arrangement revealed an artificial atmosphere, and these fluorescent moss was most likely planted by artificially.

This is not the most obvious place. The most obvious place is that there is a kind of plump grass growing between the moss on the ground. The stems and leaves of this grass are very thick, thick and long, and look very tender.
