The hovering car was still flying fast on the road, and it had been more than half an hour since it left Yuzhang City at this time, and the actual distance had left the range of a hundred kilometers. At this time www.biquge.info the hovercraft has entered the low-level density area of Yuanyuan, which is commonly known as the relative danger zone.

According to the demarcation of Yuzhang City, the 30-kilometer area centered on Yuzhang City is an absolute safety zone, and there will be thousands of sword-wielding people in this absolute safety zone to carry out close patrols at all times, ensuring that even if you see a Yuan Yuan, you will not survive.

According to the requirements, even a Yuan Yuan cannot be within 30 kilometers of Yuzhang City, because there are hundreds of thousands of people living outside the city in this absolute safety zone, even if they sneak into a Yuan Yuan, it will be a huge casualty.

However, this is obviously unrealistic, every month there are Yuan Yan touched into the absolute safety zone, launched an attack on the people outside the security zone, according to statistics, the average number of people outside the city who died every month in the last ten years is 568 people, ten years down is 70,000 deaths, the mortality rate is as high as 15%, this is the result of the strengthening of human security in the surrounding cities in the last ten years, in a few decades ago, the mortality rate has not been less than 30%. Therefore, people outside the city are really exchanging their lives for survival.

An area of more than 30 to 100 kilometers is a relatively safe zone, according to the requirements of Yuzhang City, there is no more than one yuan per kilometer, and this area is also patrolled by thousands of sword-wielding people. But the area is too large, and it is impossible for the sword wielder to completely clear this area, and there are constantly Yuan Yan from a hundred kilometers away entering the range of a hundred kilometers, and the killing is endless.

Therefore, in principle, no outsiders are allowed to live in this area. However, there are still some people from outside the city who seem to live in a relatively safe area of 100 kilometers for profit.

An area of 100 km to 300 km is a relative danger zone. Yuzhang City no longer organizes daily patrols of sword-wielding teams, but organizes a major clean-up event once or twice a month. Eliminate those who are above the ghost level with great threat, as for the ghost level and below, there is not so much time to deal with them at all.

As for the distance of three hundred kilometers, it is completely a paradise for the Yuanyuan, and when they reach that area, human beings have changed from hunters to prey, from sweepers to cleaners, without the guidance of high-level sword-wielders, low-level sword-wielders used to be similar to looking for death.

Meiling Mountain is just outside the relative safety zone. That is, 100 kilometers outside the area, about 120 kilometers or so of the line, here is in the junction of security and crisis, although this area is not much, but Meiling Mountain is a sitting, which means that there are lush forests, all kinds of complex terrain, all kinds of hidden places, to clear the Meiling Mountain Yuan Yuan is almost an impossible thing.

Originally, it was because of the existence of dimensional crystal ore. Yuzhang City intends to build Meiling Mountain into an absolute safety zone, and let the people outside the city be responsible for the large-scale mining of the dimensional crystal mine, and the sword bearer is responsible for protection. The idea was good, but after a few years of fumbling it turned out that it was simply not realistic.

Because even if the original Yuan Yan of Meiling Mountain was cleared. However, Meiling Mountain is located in a dimensional crack prone area, and hundreds of small dimensional crack eruptions are recorded every year. In addition to bringing countless dimensional crystal ores to Meiling Mountain, these dimensional cracks also brought a lot of yuanyuan. Every day, a new Gento enters this world through dimensional rifts.

In the years when it was designated as an absolute security zone, there were more than a hundred sword-wielding men stationed on Meiling Mountain. However, hundreds of people from outside the city still die every day due to the sudden jump out of the dimensional rift, and in a month, there are 3,000 casualties. More than the death toll in the absolute security zone, thirty kilometers outside the city. After a long time, even if the outsiders were killed, the outsiders were not willing to go to Meiling Mountain to work, and over time, Yuzhang City completely gave up the plan of using outsiders for large-scale mining, and changed back to the mode of issuing tasks for sword wielders to carry out small-scale mining.

After getting off at the safe camp at the foot of the mountain, Gu Han and the others, under the leadership of Luo Fan, officially entered the Meiling Mountain and began their first life outside the city.

There are many dimensional ore veins in Meiling Mountain, and they are also very messy, so it can be said that the entire mountain may contain scattered dimensional crystal ore veins. Because the dimensional crystal ore is a vein produced after the dimensional crack is opened, the sword element leaks out of the dimensional crack, penetrates into the surface, and fuses with ordinary soil and rock.

In other words, as long as a dimensional crack has been opened in a certain location, then there must be a vein of dimensional crystal ore in this place, and the difference is only a matter of the amount of ore vein. It is estimated that as an area with a high incidence of dimensional rifts, there have been hundreds of thousands of dimensional rifts that have erupted here in the past thousand years.

The frequency of hundreds of thousands of times is spread evenly on this Meiling Mountain, and almost every inch of land has erupted dimensional cracks, and the entire Meiling Mountain contains veins of dimensional crystal ore, but most of the dimensional crack eruptions are too large, and the dimensional crystal ore produced has no mining value.

There are about 700 ore veins with mining value on Meiling Mountain, of which more than 400 are small ore veins, more than 200 are small ore veins, more than 20 medium ore veins, and three large ore veins.

Yuzhang City has established official camps on the three large ore veins in Meiling Mountain, Luo Fan is now leading his students to move forward with the nearest Luo Ting camp among the three major ore veins, according to Luo Fan's plan, the accommodation point for these five days is in the Luo Ting camp, after all, he is leading a group of newcomers with zero actual combat experience, and he still has to do his best to ensure safety, and don't do anything dangerous like sleeping in the wild.

On the way to Luoting's camp, a mountainside was turned, and an extremely impactful scene appeared in the eyes of everyone in Class 22694. On the left side of the road, a sinkhole more than 100 meters deep and several square kilometers in size suddenly appeared, which looked like a semicircle of ice cream had been scooped out of a box of ice cream.

However, unlike other naturally formed sinkholes, the soil is not the red soil unique to Jiangxi Province, but a pitch black soil like the black soil of Northeast China.

It stands to reason that black soil is rich in nutrients and is particularly suitable for vegetation growth. But this sinkhole doesn't say what kind of tree it is, and not even a single piece of grass can be seen, which perfectly explains what it means to not grow an inch of grass.

"Students, do you know how the sinkhole you see now was formed?" Seeing that his students were curious about this sinkhole, Luo Fan took the initiative to ask.

In response to Luo Fan's question, the students shook their heads one after another, saying that they didn't know what the reason was. Luo Fan smiled knowingly, how could these students know the origin of this sinkhole, now is the time for themselves to pretend to be forced and show their rich knowledge.

"I know!!" Just as Luo Fan was about to open his mouth to explain, a very uninteresting hand stretched out, and Luo Fan could only smile bitterly when he saw that it was the little ancestor of Liu Nian Rin, "Ao Rin, let's talk about it, how this sinkhole was formed." ”

"Of course, this sinkhole was formed by the battle, you look at these pitch-black lands, this is not some kind of natural land, these are all caused by evil magical forces. Depending on the situation, this sinkhole has been formed for at least five hundred years, and the color is still so pitch black, it seems that the source of this evil magical power is a very powerful Yuanyuan. ”

"It turns out that Liu Nian Rin only analyzed the sinkhole formed by a battle by analyzing the soil, and he didn't know the true origin of this sinkhole, it seems that he still has a chance to show off......" Luo Fan breathed a sigh of relief, and when he was about to explain again, he was once again robbed of the conversation.

"It's Medusa, there used to be a Medusa of the Universe level, and there was a battle with the sword-wielder here...... "Gu Han silently stared at some of the stones under the sinkhole, "It was really a tragic battle. ”

"Medusa! It's still the Medusa of the Woo class! Wouldn't that be as powerful as an immortal sword-level sword wielder! One of the classmates exclaimed.

"Oh my God, it's terrible, I've heard that Medusa has magic that can take human souls...... It's horrible. Hearing Gu Han's words, the classmates suddenly exclaimed, they didn't expect that there was actually a Medusa who fought here.

"Gu Han and Ao Rin, are right, there is indeed a Yu-level Medusa here who has had a big battle with our sword wielder." Luo Fan quickly took over the conversation.

"Five hundred and sixty-one years ago, there were no three major ore veins in Meiling Mountain, and there was only one large ore vein, the Huangfeng ore vein. One day, the sword-wielding people in the Huangfeng camp suddenly discovered that at Luo Ting's location, a huge crack in the sky suddenly opened dozens of kilometers long. Streams of blood-red light floated out from the crack, and the sword-wielders of the Huangfeng camp knew that danger was coming, it was a huge dimensional rift, and thousands of Yuan Yan would pour out of this dimensional crack and launch a terrifying attack on Meiling Mountain. ”

"The sword-wielders in the Huangfeng camp knew that the best way at this time was to flee for their lives as soon as possible, desperately fleeing for their lives, and fleeing back to Yuzhang City. However, there are tens of thousands of people outside the city in the Huangfeng vein camp. At that time, hovercraft had not yet been invented, and humans could only rely on modified superbuggies to act. However, the number of off-road vehicles in Huangfeng's camp is not enough, and a maximum of 3,000 people can be transported to retreat at a time, and it is impossible to evacuate people from outside the camp in a short period of time. ”

"Therefore, the sword wielders of the Huangfeng camp decided to let all the young children, only children, fathers, young powerhouses, and women in the camp evacuate first, and all humans over the age of thirty should stay in the camp to delay the retreat with their own lives." (To be continued.) )
