Hao Qi followed Zhang Heng and was heading to an underground passage.

According to Zhang Heng's introduction, the territory of Baicao Kingdom belongs not only to the surface area, but also to a territory with a larger area underground than the surface area of ​​Baicao Kingdom, that is, the underground environment.

Baicao Kingdom is located at the intersection of mountains, in a large valley among the mountains. Geological disasters such as earthquakes have rarely occurred in this area since ancient times to the present. At the same time, with people's exploration and discovery, in the caves and cave areas of Baicao Kingdom, there are very large spaces under the ground of Baicao Kingdom. The small ones have about a few houses, hundreds of square meters in size, and the large ones are the size of towns and even cities. These hollows are connected to each other, and they are stacked from top to bottom, forming the unique geographical environment structure of Baicao Kingdom.

Moreover, according to Zhang Heng, the underground hollows of Baicao Kingdom are extremely vast. The areas explored at present are almost far more than the size of Baicao Kingdom itself. They are divided into three layers from top to bottom. The bottom area is more than 1,000 meters deep. Moreover, there is still a larger area downward, and even horizontal exploration is only the beginning. The distance direction of one of the tunnels has been explored is marked, and it can extend to the northern border of the Blue Ocean, but there is no exit to the ground.

In fact, this is not the unique geological environment of Baicao Kingdom. According to the ancient books that Zhang Heng read, many countries in the Orange Sea area among the seven seas have developed underground. It is said that it is a three-dimensional area, and Chenghai is also a three-dimensional ocean. I haven't seen it myself. What I see from the books is simply unimaginable.

Although Hao Qi has read a lot of books over the past few days, most of them only introduce the humanities, history, or customs and customs of the Blue Ocean. Even if there are, there are only a few sentences. Most of the books that introduce the situation outside the Blue Ocean are collected by aristocratic families or imperial royal families. Similar introductions are basically collected by various forces, such as sects, organizations, universities similar to Zhang Heng's study. Hao Qi has only been traveling and searching these days, but he has not found these books.

After hearing Zhang Heng's detailed explanation, Hao Qi felt really excited and wished he could see the endless wonders immediately.

During the chat, the two had already gone to the foot of the mountain and followed the small path between the hillside and headed towards the underground tunnel that Zhang Heng mentioned. When they came outside this small cave in the mountain, it was about noon. According to Zhang Heng, it was not dark underground. Although there was no light in many places, there were bright plants in many large areas of holes below the ground. Although it was just a faint light, at least you could barely see the objects and would never fall into absolute darkness.

Since this was the case, Hao Qi felt that there was no need for any delay, so he immediately entered the cave with Zhang Heng. The two of them entered the cave with the torch prepared in advance. On the first day of the first day, the cave was narrow. Zhang Heng and Hao Qi had to bend down to enter in some places. However, as they penetrated into the cave and went deep into the ground, gradually, the passage began to become wide. Under the torch, various strange stones, rock walls, and stalactites were all presented in front of Hao Qi. He walked and looked around, his eyes full of surprise.

Zhang Heng did not notice this. He walked ahead and stopped from time to time to pick up the map to look at it. Hao Qi also looked at the map. It was obviously not an official printed map, but a map depicted and outlined by Zhang Heng himself. There were small text descriptions in some details, which were described in detail. Zhang Heng was walking and stopping like this, and took Hao Qi away for about four or five hours. If he was on the surface at this moment, he would probably have seen the afterglow of the dusk.

At this moment, Zhang Heng looked at the map and pointed for a long time, and finally took Hao Qi to deflect several small holes in succession. Then the two of them suddenly realized. The big green and shiny Qinlin District appeared in front of them. Mushrooms of all sizes grew in this area, with a height of dozens of meters, and an average of about ten meters. There were also some small mushrooms just under their feet. They looked no different from the mushrooms that Hao Qi had eaten on weekdays, or the only difference was that the mushrooms here all emitted a faint green and shiny light.

"...This is a green mushroom, which cannot be eaten or used as medicine. Once it grows to a height of one meter, the mushroom will fibrous. If it grows to a height of five meters, the mushroom will become a wood-like material. This mushroom will emit a faint green light. This light can attract a large number of insects underground. Most of the nutrients required for the growth of mushrooms come from the excretion and corpses of these insects. At the same time, the mushrooms also provide the growth environment needed by the insects, and the spores of the mushrooms can also be eaten by the insects, so a simple underground biological system is formed."

Zhang Heng looked at the large area of ​​mushroom wonders in front of him, and he talked endlessly to introduce him to Hao Qi. As expected, Hao Qi was also very excited and wanted to enter the mushroom forest immediately.

Zhang Heng immediately grabbed Hao Qi and said, "Brother Hao, don't enter it at will. There are many poisonous insects in those insects. If you are accidentally bitten, if you encounter a very toxic one, even Brother Hao may not be able to resist it. There is only one way to enter it, that is, burn the woody material of this mushroom, which will produce a kind of smoke specifically targeting insects. It's okay for people to breathe, and there is a faint fragrance. However, it is highly toxic for insects. There are various poisonous insects here, and beasts underground will not come to your door at will, so it's safe to set up a camp here."

Hao Qi then looked at Zhang Heng and said, "I can't tell, you know a lot about the biological system. Are you not a medical student?"

Zhang Heng forced a smile, as if it was a bit indescribable. After a long time, he said: "Actually, I am more interested in biology. I want to find the terrain environment produced by hidden treasures. In fact, I also want to study the ecosystem there. In comparison... medicine is my profession."

"So? Promote blood circulation and remove blood stasis, nourish yin and yang?" Hao Qi couldn't help but tease this when he heard Zhang Heng say this, because along the way, the two of them also saw many herbs. When Hao Qi asked about the efficacy of these herbs, eight out of ten, Zhang Heng would comment on these herbs like this, promoting blood circulation and removing blood stasis, nourishing yin and yang.

Zhang Heng suddenly turned red and murmured: "Always, I can't get rid of blood circulation and blood stasis, nourishing yin and nourishing yang..."

Hao Qi shrugged indifferently, and the two of them didn't say anything more. Hao Qi took pieces of wood from some tall mushrooms according to Zhang Heng's sign, and then selected a place that was neither in the mushroom group nor outside the range of ghost light to build a camp. Then he lit the wooden mushrooms, and a faint blue smoke suddenly rose from the fire. Then, Hao Qi had goose bumps all over his body.

Just under his feet and in the camp, dense insects emerged from the ground, as if the two of them were standing in an instant, and Zhang Heng seemed extremely calm. Obviously, he had experienced this situation more than once. In just a few minutes, a large number of insects escaped from the camp, and Hao Qi was completely stunned.

"Okay, that's fine. The bonfire cannot be stopped. The fuel is made of this mushroom material. Until we leave, no insects will approach. By the way, the meat produced by this fuel will have a special fragrance and make the barbecue more delicious." Zhang Heng did not notice Hao Qi's horror. He just calmly and looked at everything in the camp with satisfaction.

Hao Qi slowly came to his senses at this time. He happened to hear what Zhang Heng said about the special barbecue. His mouth suddenly had a scent and immediately said, "That's good, I'll go and catch some prey immediately... By the way, are there prey underground?"

Zhang Heng smiled and affirmed, and also mentioned in detail several species of frequently-occurring creatures. Most of them are small and medium-sized rodents, similar to rats and squirrels, but there are also two types of organisms that are large organisms, one is an underground python, and the other is an underground terror, especially an underground terror. Zhang Heng emphasized that this is an amphibian creature, which is more than three meters long after adulthood, and can grow almost infinitely with the age of age. Once its length exceeds twenty meters, this creature is a vicious creature. Of course, it is very rare. The meat of this creature is very delicious and a delicious dish for the powerful people on the surface, but the quantity is very small. It can be said to be a rare treasure that can be found.

In the underground world, cherish the delicious food, and there are very few, and there may be evil creatures...

Combining these things, Hao Qi was so excited that he wanted to scream. Isn’t this the dream he had always dreamed of!? Isn’t this what he wanted to pursue and find!? Experience, adventure, living, pursuit...

Traveling through the unknown places in the world, seeing what others have never seen, finding what others have never found, and getting what others have never found!!

Although this place must have been explored, and I don’t know how many people have explored it, and the underground horror salamander has probably been hunted by countless people, these are still unknown and unseen places for him! Moreover, if he wants to travel all over the world, he wants to see all over the world, there are always those mysterious places, those out of the world, and those dangerous places, which are places that others have never been to, explored, and even discovered, as well as those unknown creatures and unseen treasures...
