"The fire pillar just now was so weird." Catherine stared blankly at the passage after the flame pillar disappeared. At this time, she found some small differences in the hollows in the underground, such as the burning black on the four round walls, such as some crystallized parts in the crypt, such as no animals and plants growing near the crypt, all of these small details proved the high temperatures that may appear here.

"How did these pillars of fire appear?" Vivian searched the knowledge in her mind, but could not find the reason: "It must not be a volcanic eruption, nor a burning, nor an explosion. What is the principle?"

"No one knows." Ike spread his hands: "I used to call this the King of Hell's breath, and I think it's quite vivid. But that's just a joke, and these are not accidental phenomena. You can encounter many such fire-breathing points in these layers. The fire-breathing time is quite accurate, and the error will not exceed one minute."

"Tsk tsk." Vivian shook her head and did not comment any more. She just stared at the place where the flame column had been spit out with confusion. Lina patted her head and pushed her to follow the team forward.

Although it is very hot, the vegetation covers an extremely vast area. Almost most areas are covered by thick grasslands, and occasionally a few short trees grow on the grasslands. The glory of crystals seems to have replaced the role of sunlight to a certain extent. The leaves of these grasslands and short trees are actually green like the outside world. Walking here always has the illusion of returning to the ground world. But everyone has a sense of incongruity in their hearts. Everyone really can't understand that in such a hot area, these rich plants. What source is their water intake? After all, although the ground is a thick layer of soil at a depth of thirty or forty meters, there is hard rock below the soil layer, and there is not much groundwater. What do plants rely on to live?

"Don't look at the heat here, but do you still remember the passage when you came down? It looks like the ground of the river. In fact, you came here just in time. If you came here in June and July, you might not be able to get in at all. Because it was the flood season at that time." Ike explained: "In June, July and August every year, due to the sufficient rainfall outside, there will be a three-month flood season. The underground underground river level in each layer will surge, and each layer will be washed and moisturized by a large amount of river water. These plants rely on these three months.

The number of precipitation is a living. Of course, the other nine months except these three months are not completely drought. Occasionally, river water levels will rise and wash away the underground world, but it is a relatively small number of times. Therefore, these three months plus the first and second months are called rainy season, while the other eight months are called dry season. If you can see it later in October, the grass and trees here are withered and yellow, and they look like they are dead, but by the second rainy season, they will recover again."

"I have to admit that nature is really magical." Catherine shook her head and exclaimed: "If you don't see this in person, you will never think of this world with only two seasons in a year."

In the world, there are a large number of small herbivores living in thick grasslands. These strange and strange animals are like their relatives on the ground. They live on the vast underground grasslands. Rabbits without long ears, only pony at the waists of people, and deer with long tails. These creatures have one common feature, that is, their animal hair is very short, and it seems to be to minimize the accumulation of calories in their bodies to fight the hot environment.

Similarly, there are a large number of carnivorous monsters on the grassland. These carnivorous monsters of varying sizes are quite fierce, even small monsters. Their power and speed are much stronger than the various insects on the above layers. Perhaps it is because the food on the underground grassland is abundant, or perhaps it is because these monsters are much smarter than insects. They rarely attack the people of the adventure group. When the members of the adventure group pass by, these carnivorous monsters will only observe them from afar with vigilance and curiosity, and unless they are extremely hungry, they will not regard these unseen creatures as food.

However, there are exceptions in everything. There will be some monsters that are too stupid to catch prey. They are so hungry that they don’t care about these creatures they have never seen before. They greedily follow the adventure group while walking, maintaining a distance of not too far to spy on opportunities. Once a loophole is found, they may attack everyone at any time.

However, a few minutes later, the following monsters suddenly made a neat sob, lowered their heads and ran into the long grass and escaped, never willing to come back. Catherine smiled gratefully at Panis and gave a thumbs up. In fact, the reason why those monsters escaped was very simple. Panis used the inherent spiritual realm to strengthen himself and release the pressure of the demigod. Perhaps for humans, this pressure is not obvious. People who are more slow may not be able to sense it at all, but for these monsters, it is different. Even the slowest monsters are very sensitive to this powerful pressure. In the eyes of these monsters, Panis instantly becomes even more terrifying than the most powerful predator, allowing them to instinctively stay away from the team.

"These monsters are indeed much smarter than the bugs on the top of the top." Panis said: "The bugs often rely on instinct to act, eat and sleep when they are hungry, regardless of whether they can defeat their prey. But these monsters are different. They can already tell the strength of their strength, and they are really close to the surface. But why are they in deeper underground, rather than those bugs here?"

"No one knows the answer," said Ike. "It has been like this since many years ago, and I don't know how many tens of thousands of years it will last. As for the reasons, who will care except those scholars."

"Wait." Catherine suddenly waved her hand and stopped the team, quickly ran to a naked rock and said, "You see here. It seems that there are artificial items. It seems to have been many years of history. Will it be related to the target we are looking for?"

The rest of the people looked tight and surrounded the rock. Above the rock, as Catherine said, there were many metal products with obvious artificial traces, including rusted knifes, metal cans, locks, metal chains, and fixing items such as metal brazing. But after seeing this, Panis shook his head and said, "These should be traces left by explorers a long time ago. Just like if another group of people came here to explore thousands of years later and found the traces of camping on the seventh floor, it would probably be like this. However, they seemed to be in a hurry and many things were not taken away."

"This shouldn't be a matter of haste." Ike said: "It seems that they were attacked very suddenly, and the intensity of the attack makes it difficult for them to fight, so they hurriedly escaped. Of course, there is a greater possibility that they died directly nearby and all the teams were destroyed, so there was no chance to pack up."

"This story is not good at all, but it is absolutely true." Catherine sighed, not only expressing regret for the victims, but also sighed that these are not relics of goblins: "Since it has nothing to do with goblins, I have to continue looking for them. By the way, do you need to bury these things for them? After all, it may be considered relics."

"No need at all, there is no need to do this in this underground world." Ike shook his head and said, "All the relics of the victims or escaped people can be used if they are found. When they cannot be used, they will be placed in place without moving them. Wait for the next time others passing by. Maybe when these relics can save the lives of a certain group of teams."

"These rules seem to be close to many of the rules of sailing on sea." Catherine nodded and said, "Maybe all kinds of high-risk wild professions have similar rules. After all, this is for others, and it is for yourself to consider another direction."

After confirming that these things have nothing to do with the goblins, everyone can only start to explore within a range of 50 kilometers near the Ground Seal in disappointment. When exploring, they can no longer pass quickly like the previous seven floors. To truly explore an area, they need to divide the area into several parts or dozens of parts that are slightly smaller than half of the area of ​​this scale according to the pre-estimated target building scale, and then carefully screen each part, and no details can be missed. Especially in the winding environment of the Ground Seal underground world, it is very likely that a very inconspicuous cave is the only channel to the target.

This is a very tedious and complicated task that requires great patience to proceed smoothly, but in addition to this, everyone has also discovered another feature of the monster. It seems that the monsters know that these people in the adventure group are difficult to deal with. Many hungry monsters replaced the follower's team waiting for an opportunity to hunt for lurking and hunting. They lurked in the long grass, lurking behind the trees, lurking in the corner of the tunnel, and lurking behind the stone pillars that support the cave. As long as the girls are slightly distracted and revealing the gap, several monsters will rush out from the inexplicable place. Even Pannis cannot remind him in advance, because there are so many lurkers around that they cannot remind him at all.

However, the girls' absolute strength is invincible even when they cooperate. It only took a short time to find an effective way of confrontation between sneak attacks and being sneak attacks. In the end, Katherine, as a knight, mainly defended and hardly participated in the search. Any monster that suddenly rushed out and attacked would be hit by the female knight. The other girls cooperated with Panis to search for every possible area. After this division of labor, the speed was much faster.
