Through the clouds, you can see the vast expanse of the sea.

In the blue sky, only the sound of helicopter rotors turning and waves crashing remains.

It was a small helicopter, and in addition to the pilot, a teenager in an expedition suit and a woman sat in the back.

Tingshu and Judge Joey set off from Saiyu City and set off on an alliance's special helicopter to set off on an uninhabited desert island.

Looking down from the trees, the island looks lush and oval-shaped, but the whole island is surrounded by cliffs, there is no beach, and you can hear the waves crashing against the reef at all times.

"The two of us need to spend a week here after going down, and there is no other way to leave except to leave by helicopter, and the ship cannot dock on this island." Judge Joy said.

The peculiarity of this uninhabited desert island has cut off the possibility of communication with the outside world by boat.

However, in addition to helicopters, you can also leave by flying elves, but if you want to leave by riding elves, not all trainers have that ability.

Tingshu was not worried, he and Tanabata Bluebird had gone through the whole process of flying from Qishui City to Yantu Mountain, and this uninhabited desert island was even closer to the uninhabited land than that.

"Before I go down, I would like to remind you that this uninhabited desert island is a D-level lost area, which is dangerous, and you can choose to ask me for help, but your final rating will be reduced, so try to overcome the difficulties yourself."

Tingshu nodded, and at the same time asked puzzled: "D-class lost region?" ”

Examiner Joy explained: "This is the name of the past, and now it is only used on a small scale, which is probably an assessment of the degree of danger. ”

Tingshu thought for a moment, he seemed to have seen a description in a certain classic, "Orange Blossom Forest, Fangyuan Desert, and Volcano are also considered to be rated as lost areas?" ”

"I was." Examiner Joey looked at Tingshu in surprise.

"The Orange Blossom Forest used to be a D-rated lost area, while the Fangyuan Desert and the Volcano were C-class, but now the danger has been cleared and is not included in the rating."

"Speaking of which, the danger rating in the wild area is also related to the gym, and the two policies were promulgated at the same time, but now they have faded out of most people's sight."

Tingshu's curiosity was mobilized at once, it was knowledge that he didn't know, and he immediately humbly asked for advice.

About 150 years ago, the first Elven League Conference was held, and before that, the League had been established for some time.

The promulgation of the gym policy was still before the Elven Alliance Conference, and the people who could serve as the trainers of the gym at that time were all the most powerful trainers in the local area.

Their only duty is not to test the rookie trainers, but to prevent the local cities and towns from being invaded and destroyed by wild elves.

More than a hundred years ago, human settlements were not such high-rise buildings as they are now, and technology was not developed, and in the face of the invasion of wild elves, ordinary people except trainers had no power to fight back.

The role of the hall master is to guard a town, similar to the local patron saint.

The gym is also mainly built in those places that are relatively close to the danger area, just like the Changpan Forest in the Guandu area, which was once listed as a C-level lost area, and there are many elves in it, and from time to time they will break out of the forest and enter the city, causing a certain amount of trouble to the residents, and the responsibility of the gym owner is to cooperate with the local police to maintain law and order, and even if necessary, enter the lost area alone, find the source of the elf riot and solve it.

At that time, the most important factor in referring to the strength of a gym trainer was to look at the dangerous difficulty rating of the Lost Area of the place he was guarding.

A hundred years ago, the Daoist Gym Master was a middle-level figure who could speak even within the Alliance.

And now, with the development of science and technology, wild elves want to invade big cities, there is no such possibility, there was a tyrannosaurus attacked a small town, but it didn't take long for it to be defeated by the folk trainers who organized themselves, and the powerful elves were also expelled to the area far away from humans at this time, since the rise of human beings, the task of the gym trainer to protect the town has gradually been reduced, and even now it is said that it is a test of the idle job of a newcomer trainer can also be said to be in the past.

Therefore, if you want to become a gym trainer now, it is not more difficult than before.

"In other words, if you wanted to become a gym trainer more than a hundred years ago, you would need at least a personal individual combat ability, and be able to enter and exit the D-level lost area unscrupulously?" Tingshu gained insight again.

This is his blind spot in knowledge, and there are some things that he naturally cannot know all about.

"In this way, I'm quite lucky...... Tingshu said in his heart, if he had traveled back two hundred years, at the beginning of the alliance's establishment, he might not even be able to eat.

There are 5 levels of Lost Regions.

d、c、b、a、s。

Grade D is the least dangerous and Grade S is the largest.

Like this uninhabited desert island, the undeveloped Orange Blossom Forest is equivalent to a D-level danger area, and the uninhabited desert island is far away from the town, so you don't have to worry about it, but the Orange Blossom Forest is between the two cities, so there are two gyms built around it from a hundred years ago to guard and take care of it.

"How dangerous is the Class-D Lost Zone?" Tingshu is puzzled, there is no exact reference, the undeveloped Tokiwa Forest was originally a dangerous area belonging to the C-class lost area, but now it has been developed and even the rookie trainer can safely pass through it if he walks carefully, and has been kicked out of one of the lost areas, but even so, if the rookie trainer provokes the flock of flaming birds, he will also lose his life, but this cannot be used as a reference for the garden tree to judge the danger of the D-class lost area.

"Like Silver Mountain and Tianguan Mountain, they all belong to A-level lost areas, and they can't be completely conquered with the strength of trainers." Judge Joy said.

"So the quartz plateau was built next to the Silver Silver Mountain, in order to guard the Silver Mountain in case of accidents."

"Silver Mountain is only A-grade, but what about S-grade?" Tingshu was stunned.

Examiner Joy said: "Okay, that's not what you can know now, if you want to figure it out, just pass the assessment, and then you will have the ability to touch some things." ”

Tingshu was silent, the helicopter stopped, and it was at the place.

"Let's go down with a rope."

"Okay." Tingshu Road.

Although Joey didn't say where the S-Class Lost Region was, Tingshu had a few guesses.

If there is any place that is more dangerous than the depths of Silver Mountain and Tianguan Mountain......

The garden tree looked at the vast sea below, the deep sea must be one of them, and the universe above the ozone layer is difficult for humans to touch.

Or......

The habitat of some ghosts and ghost elves, the spirit world and other alien spaces that cannot be explored by humans.
