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

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

Baicao country is located in the intersection of mountains, in a large valley area in the mountains, and this area has rarely occurred geological disasters such as earthquakes since ancient times, at the same time, with the discovery of people's exploration, in the caves and cave areas of Baicao country, it was found that there is a very large space under the ground of Baicao country, the small one has a few houses, hundreds of square meters in size, and the large one has the size of a town or even a city, these hollows are connected to each other, and from top to bottom, layer upon layer, forming a unique geographical environment structure of Baicao country.

And according to Zhang Heng, the underground cavity of Baicao Country is extremely vast, and the area that has been explored so far has almost far exceeded the size of dozens of times the area of Baicao Country itself, and it is divided into three layers from top to bottom, and the bottom area is already more than 1,000 meters deep, and this has not yet reached the end of exploration, there is a larger area down there, and even the lateral detection is only the beginning, and the distance direction of one of the tunnels that has been explored so far indicates that it can already extend to the northern border of the blue sea, but the exit to the ground has not been found。

In fact, this is not the unique geological environment of Baicao Country, according to the ancient books that Zhang Heng read, the Orange Sea region in the Seven Seas, where many countries have developed underground, it is said that it is a three-dimensional existence of the area, and Chenghai is also a three-dimensional ocean, but I haven't seen it in person, just from what I saw in the books I can't imagine at all.

Although Hao Qi has read a lot of books in these days, most of them are only about the humanities and history of the blue ocean, or the customs and customs, and there are few books about the areas outside the blue ocean, and even if there are, there are only a few sentences, and those books that introduce the situation outside the blue ocean, most of them are written in detail are the collections of the big families or the imperial family, and similar to the general introduction, are basically in the collections of various forces, such as sects, such as organizations, such as universities similar to Zhang Heng, and Hao Qi only cares about traveling and looking for these days, but he has not found these books。

Listening to Zhang Heng's detailed talk at this moment, Hao Qi's heart was really excited, and he couldn't wait to see the infinite wonders and wonders immediately.

In the chat, the two have gone down to the foot of the mountain, and they followed the mountain path on the hillside, towards the underground tunnel that Zhang Heng said, and when they came to this small cave in the mountains, the time was about noon, according to Zhang Heng, it was not dark underground, although there was no light in many places, but there were many large areas of bright plants in the hollows underground, although it was only a ghostly light, but at least you could barely see, and it would never fall into absolute darkness.

In this case, Hao Qi felt that there was no need for any delay, and immediately drilled into the cave with Zhang Heng, and the two of them carried the torches prepared in advance and drilled into the cave, as soon as they entered, the cave was narrow, and in some places Zhang Heng and Hao Qi had to bend down to enter, but as they went deep into the cave and went deep into the ground, gradually, the passage began to become wide, under the illumination of the torches, all kinds of strange stones, all kinds of rock walls, all kinds of stalactites and the like were presented in front of Hao Qi's eyes, he looked left and right while walking, and his eyes were full of surprises.

Zhang Heng didn't notice this, he walked in front, stopped from time to time to pick up the map and looked, the map Hao Qi also read, obviously not the official printed map, but Zhang Heng's own handwriting description and outline of the map, some details There are small text descriptions, the description is very detailed, and Zhang Heng is in this stop-and-go, taking Hao Qi for about four or five hours, if it is on the surface at the moment, it is estimated that you can already see the afterglow of dusk.

At this time, Zhang Heng looked at the map and pointed for a long time, and finally took Hao Qi to deflect several small holes in a row, and then the two of them suddenly opened up in front of them, and what appeared in front of them was a large green and shining Qinlin area, large and small mushrooms grew in this area, the big ones were tens of meters high, and the average was about ten meters, and there were also some small mushrooms at the feet, which looked no different from the mushrooms that Hao Qi had eaten on weekdays, or the only difference was that the mushrooms here all exuded a faint green glow。

"...... this is a green mushroom, can not be eaten, can not be used in medicine, once it grows to a height of one meter, the mushroom will fibrosis, 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 in the ground to gather, and most of the nutrients required for the growth of mushrooms come from the excretion and corpse of these insects, at the same time, mushrooms also provide the growth environment that insects need, and then the spores of mushrooms can also be eaten by insects, so a simple underground biological system is formed。 ”

Zhang Heng looked at the large mushroom scene in front of him, and he introduced it to Hao Qi endlessly, and Hao Qi was really interested, and he couldn't wait to enter the mushroom woodland immediately.

Zhang Heng immediately grabbed Hao Qi and said: " Brother Hao, don't enter it at will, there are a lot of poisonous insects in those insects, if one is accidentally bitten, in case of encountering a poisonous one, even Brother Hao may not be able to resist, there is only one way to enter it, that is to burn this mushroom lignified material, which will produce a kind of smoke specifically for insects, people are fine to breathe, and there is a faint fragrance, but it is highly toxic for insects, and there are all kinds of poisonous insects here, and the fierce beasts underground will not come to the door at will, so it is safe to set up a camp here。 ”

Hao Qi looked at Zhang Heng and said, "I can't see it, you know a lot about biological systems, aren't you a medical student?"

Zhang Heng smiled reluctantly, it seemed to be a little unspeakable, and he said after a long time: "Actually, I am more interested in biology, I want to find the terrain environment produced by those hidden heavenly treasures, in fact, I also want to study the ecosystem there, compared to ...... Medicine is my profession. ”

"So, invigorate blood and dispel blood stasis, nourish yin and replenish yang?" Hao Qi heard Zhang Heng say this, and couldn't help but ridicule him, because along the way, the two of them also saw a lot of herbs, and when Hao Qi asked Zhang Heng about the efficacy of these herbs, Zhang Heng would comment on these herbs like this, invigorating blood and removing blood stasis, nourishing yin and replenishing yang.

Zhang Heng's face suddenly turned red, and he muttered: "Anyway, you can't get rid of the blood circulation and blood stasis, and the category of nourishing yin and replenishing yang is right......

Hao Qi shrugged his shoulders indifferently, and the two of them didn't say anything at the moment, Hao Qi took off the wooden materials on some tall mushrooms according to Zhang Heng's instructions, and then chose a place that was neither in the mushroom group nor out of the dark light range to build a camp, and then lit these mushroom wooden materials, and a faint green smoke suddenly rose from the fire, and then, goosebumps rose all over Hao Qi's body.

Just under his feet, and in the camp, dense insects came out from the ground and underground, as if the position where the two of them were standing became a sea of insects in an instant, but Zhang Heng looked very calm, obviously he had experienced this situation more than once, and in the next few minutes, a large number of insects fled the camp, and Hao Qi was completely stunned.

"Okay, that's it, the campfire can't be stopped, the fuel is this mushroom material, so that until we leave, no insects will come close, by the way, the meat grilled by this fuel will have a special aroma, which will make the barbecue more delicious. Zhang Heng didn't notice Hao Qi's horror, he just looked at everything in the camp very calmly and with satisfaction.

Hao Qi slowly came back to his senses at this time, and happened to hear what Zhang Heng said about the special barbecue, and the taste in his mouth suddenly rolled, and immediately said: "Then dare to be kind, I'll go catch some prey immediately...... By the way, is there prey underground?"

Zhang Heng smiled for sure, and also elaborated on several creatures that often haunt, most of them are small and medium-sized rodent creatures, similar to mouse squirrels or something, but there are also two kinds of creatures that are large creatures, one of which is the underground python, and one is the underground dinosaur, especially the underground dinosaur, Zhang Heng emphasized that it is an amphibian, which is more than three meters long when it grows old, and it can grow almost indefinitely with the growth of age, once its length exceeds twenty meters, this creature is a fierce creature, of course, it is very rare, this creature is very delicious, it is a delicacy for the magnates on the surface, but the number is very smallIt can be described as a cherished delicacy that can not be found.

The underground world, cherishing delicious food, the number is very small, and there may be fierce creatures......

The combination of all these things made Hao Qi so excited that he wanted to scream, isn't this the dream he has always dreamed of!?Isn't this what he wants to pursue and find!?experience, adventure, life, pursuit......

Walk through the unknown places of the world, see the unseen, find the unseen, and win the unseen!!

Although this place must have been explored, and I don't know how many people have explored it, and the underground dinosaurus is estimated to have been hunted by an unknown number of people, but these are still unknown and mysterious places for him! And he wants to travel all over this world, he wants to see all over this world, there are always those mysterious places, there are always those places outside the world, there are always those dangerous places, which are places that no one else has ever been, have never explored, and have never discovered, and there are also those unknown creatures, undiscovered treasures......

He must be visited!
