Hao Qi searched for at least five or six hours underground, hunted seven or eight small animals along the way, and hunted an underground python with a length of at least four meters or so, but unfortunately, he did not find any trace of the underground dia salamander in the end, according to Zhang Heng, this is the underground layer area closest to the surface, and the underground dire salamander in this area is estimated to have been hunted clean, after all, an adult underground dire salamander is estimated to be sold for tens of millions of dollars at the surface auction, many adventurer teams have been wandering in the underground layer all year round, basically all that can be killed have been killed, unless you enter the second layer underground, otherwise you can't find the underground dire salamander。

However, to enter the second floor of the underground, you need to walk a long distance, and there are only two entrances to the second floor of the underground recorded by the official government, both of which are concentrated in the territory of Baicao Country that have been explored countless times, and it is estimated that it will not be possible to go there in a short time.

What's more, as Zhang Heng said, the second layer of the underground is full of dangers, not only the problem of sight lighting, in the second layer of the underground, the geological structure of some places will collapse at any time, the underground water flow in some places will change from time to time, and some places may suddenly emerge magma, and there are even more biological dangers in the second layer of the underground, the creatures there are almost two ecosystems with the creatures on the ground, different from the first layer of the underground, many of the creatures in the first layer of the underground can go to the surface, and the creatures in the second layer of the underground are almost all reproduced in it for life, without human interference and influence, no one knows what kind of terrible creatures exist there, Some creatures may parasitize the human body, some creatures may be highly toxic, and some creatures may be fierce or even mad, don't say that Hao Qi has entered an internal force realm, even if an internal force realm enters with a martial arts group, it will often die in it, and it may even be wiped out, which is almost a forbidden area for human beings.

"Forbidden Zone...... Meaning, it's barely ever explored!?"

Hao Qi bit the roast snake meat with the thickness of his arm, and asked Zhang Heng curiously.

Zhang Heng nodded and said: "Yes, although the Baicao Country, the Winning Country, the Haitian Kingdom, and several surrounding countries, as well as some large and powerful countries in the eastern region of the Blue Ocean, will organize a group of people to enter the underground exploration every few years, including many strong people in the internal force realm, but basically only the first layer of the underground is explored, and the second layer of the underground is roughly explored, as for the third layer of the underground...... The books I have seen record that so far, I have only explored twice, and each time it was led by the Inner Qi Realm, but many people died each time, including several Inner Force Realm powerhouses who died in it, so since the last exploration led by the Inner Qi Realm more than sixty years ago, more than sixty years have passed, and no one has explored the third layer underground. ”

"No one to explore, unknown, forbidden area, dangerous ......"

Hao Qi's saliva was about to flow down, he took a few bites of the snake meat in his hand, and after swallowing all the snake meat into his stomach, he continued to ask: "So, if you want to enter the third layer underground, do you need to report something to the government of Baicao Country? Or do you need any certificates, and do you need to pay anything?"

Zhang Heng was stunned for a moment, looking at Hao Qi's excited expression, he hurriedly said: "Brother Hao, although you are in the internal force realm, but the third layer of the underground is said to be full of fierce beasts, wild beasts are not as good as dogs, Brother Hao must not be reckless, it is best to think in the long run!"

"Anla, An!" Hao Qi laughed, picked up the little remaining wine and took a sip, and then said: "I am a person who wants to walk through this world alive, and I will never recklessly give my life, I just want to ask in advance what kind of conditions are needed to enter the third layer of the underground, even if I can't go now, will I still be able to go when I become stronger in the future? These things always have to be asked clearly in advance." ”

Zhang Heng hesitated for a while, and then said: " As far as I know, if you go in alone, it doesn't seem that you need any proof, report and the like, for example, after I leave the school, I can also enter the underground at will, but if it is a team exploration or hunting, and there is an internal force realm to lead the team, you need to report to the government of Baicao Country, I don't know the specific situation, but I have generally heard people talk about it, Brother Hao, you are the internal force realm, if you go to the government of Baicao Country to inquire in person, I want to get much more information than I got from me. ”

Hao Qi nodded clearly, since he left the Blue Shadow Republic, during his travels in many countries, he does have a deep understanding of this, no matter what kind of country it is, no matter what its political system is, as long as he visits the government and public institutions of the country as an internal force realm, he will be received with a very good service, for example, he went to ask about the country's battleships in the winning country, which is taboo in any country, but he visited as an internal force realm, and the result was that the country actually told him the data of the battleships, and the reception he got can be said to be perfect。

To a certain extent, the internal force realm seems to be no longer a human identity, because even if it is a big family, or the nobility of some feudal imperial countries, etc., most of them are courteous in their own country or neighboring countries, and go to distant countries, who knows who you are, at most you are richer, more magnificent, and no different from ordinary people, and the same internal force realm, it seems that you will get the same courtesy in any country, and it seems to be higher than ordinary people.

Hao Qi didn't want to comment on the rationality of this system, and he didn't want to change this system, obviously, this system is not just rising, but has been implemented in the distant past for I don't know how many years, which must have its inevitability, not to mention that as far as Hao Qi saw in several countries along the way, the internal force realm is indeed courteous in any country, but it is not the kind of high-minded, treating ordinary people as ants slaughtering at will, on the contrary, the various countries he saw along the way are basically in order, although they have not reached the level of the earth in his previous life, but the people are basically living in stability, with food, clothing, work, and law, there is order, and the technology of the thirties and forties of the twentieth century, to some extent, the world is actually not bad.

There was nothing to say at the moment, the two of them went to sleep after eating, and when the next day came, it was Zhang Heng who led Hao Qi to walk in this underground passage, along the way Hao Qi was really eye-opening, all kinds of underground wonders, such as almost a square-sized underground plants, using rhizomes to catch approaching animals, and for example, the rock wall that will emit a faint light, a large number of luminous crystals scattered in the passage and small space, and so on, although the underground scenery is completely different from the ground, but it is also strange, which makes Hao Qi excited。

Hao Qi was supposed to stay in this underground for a while longer, but Zhang Heng seemed to be in a hurry to go back to Baicao Academy, and there was only one map, so Hao Qi didn't force it, so he followed Zhang Heng to Baicao Country, but he also planned to buy a regular map from the government of Baicao Country, and then if he couldn't find a chance to make money in Baicao Country, he would simply go to the second floor of the underground to shop, if he could kill a fierce beast, then the money to buy a boat was estimated to be there.

That's it, the two stayed underground for almost three days, finally, Zhang Heng found a cave exit and came to the surface, when the two of them came out of the ground, the time happened to be noon, bright sunshine, brilliant weather, warm breeze, fresh air, no matter what made the two of them relax, feeling better than ever.

Although Hao Qi wants to explore the unknown underground, he also admits that the underground is indeed not a good place, the air is stuffy, and many places still have the smell of sulfur and stench, and at the same time, in addition to the light of the torches, there is only a little underground glimmer in the cave square, and the small environment makes people feel very depressing.

Hao Qi has planned underground exploration into a long-term matter in his heart, at least he doesn't plan to complete the exploration at one time, and go underground for a few months or even a few years, which is too crazy, anyway, listening to what Zhang Heng said, not only is there such an underground world in Baicao Country, it seems that most places in this world can be connected to the underground, so he will have more opportunities to explore in the future, and the first task now is still to make money first, and then buy his own sea boat.

The place where the two of them drilled out of the ground is still a mountainous area, but in the front, a vast and boundless plain is presented in front of the two, in the center of the plain can also see a huge modern city, the city is scattered around the manor, villages, farmland, the only exception is that there is a tall tower next to the city, the building complex is simply more dazzling than the city, all the towers are made of granite, the highest tower is two or three hundred meters high, it is completely a giant tower, and other towers are generally about 100 meters, from the halfway point where Hao Qi stands, the towers reflecting the sun shine, which is a hundred times more dazzling than the city next to it.

"There is only one capital city in Baicao Country, and the tall towers next to it are the National Medical University, so it seems that the medical university is more dazzling than the capital? I heard the legend that the inner qi realm who founded the Baicao country and the medical university is still alive and still lives in seclusion in the Baicao country, and some people even say that they live in seclusion in the medical university, I heard some foreign students who come to study abroad say that there is a master of the inner qi realm in the eastern region of the blue ocean, and half of it refers to the fact that our Baicao country may also have an internal qi realm, but no one is sure of it, so it is only half. Zhang Heng stood beside Hao Qi and said with a little pride.

Hao Qi was also interested, he made up his mind to go to the medical university to have a good look, this is a super novel building complex that he has never seen in his previous life, how can he not see it?

"Let's go, let's go, let's go to the capital today, right? Tomorrow we'll go to the medical university, hahaha, Baicao country, I'm here!!"
