The mayor is leading a group of young and old, both men and women, standing on the side of the square to welcome their arrival.

The mayor's name is interesting, it's called Kentatir, and it's not much better to pronounce.

After the basic cold noise, he pushed out a sturdy and swarthy old gentleman in the back, and the old gentleman said, "I am the project professor who is going to enter the ancient underground city this time, Fama!" Time is pressing, so I'll just say it briefly, except for the four, there are a total of nine of us who will go down to the underground city together, and the other eight are all my students. We had to get into the underground city on time after three hours, because it was only seven minutes before the city's barrier weakened enough for us to pass through! After seven minutes, the enchantment will become stronger again, and the next weakening time will be four days later, and if you miss it, you will have to wait another fourteen years. ”

He saw that the four of them were all looking at him with very focused eyes, and then he continued: "The burial city of the legendary archmage Rey after his death, which is also known as the Seal City, has ancient creatures alive in it, and those are all animals that the archmage liked to eat when he was alive, or creatures and mounts that he once pampered. There are many extremely fierce beasts guarding it. And our goal is to get Rey's handwritten scroll in there! ”

Then he looked at the four people: "Is there anything else you want to ask?" ”

Li Ping'an asked: "Who else knows this information?" What are the taboos to go inside? ”

"If I'm not mistaken, it's possible that one of my colleagues, Professor Scala, will take the students down, and when you enter the barrier, metal won't be able to pass through it, even at the weakest moment!" As a result, regular Death Guns, Energy Guns, and even Swords can't be brought in. That's why I'm looking for four. ”

His eyes looked at the four mercenaries one by one: "Miss Salma's ability is lightning, and Miss Aida's ability is ice; Mr. Li Ping'an is a pillar of fire, as for Mr. Kratos's ability is invulnerable, and another ability that has not been confirmed, and the strength of the four is also very large, and the skills are also extremely extraordinary, it can be said that each of you can withstand many normal people, which is why I will find you! In addition, I also have some abilities, my ability is penetration, which can allow matter to penetrate my body directly, which can't help others, but it can protect itself. ”

Then he turned to look at his group of young students, and said, "My students, four boys and four girls, will go down with us, and in order to reduce embarrassment, the boys will protect the boys, and the girls will protect the girls." ”

He continued: "At every entrance and exit, there is a limit on the total mass of objects entering and exiting, after which no one can pass through." I've calculated that there should be twelve or thirteen people to pass through, because the cratos are more massive, and the others are petite, so I guess we can have thirteen people to pass, and no more. ”

Then he took out a bag and handed it to a male student, saying, "Everyone's armor and eye protection can't be used, so I will also give you a mask that is completely metal-free, and this mask has some alien technology on it, so although there is no metal at all, it can indeed allow us to do short-range communication when we are inside, but this is only limited to short-range communication within 200 meters!" Many mythical beasts in ancient times were extremely sensitive to sound, so after going down, try to let all communication pass through this mask. ”

When the male students were handing out face shields, Fama took out a metal detector rod and said, "I'll check if there is any metal on everyone's bodies, and if there is, I have to leave all of them, and then take advantage of these few hours to find a non-metal replacement as soon as possible." ”

Li Ping'an was still worried: whether the ring hidden under the transparent gloves on his hand would be discovered, if it was found and could not be worn on his hand and entered inside, it would be very troublesome!

Fortunately, when the probe rod swept over his hand, it was separated by gloves, and the probe rod was completely undetectable, and did not make any beeping sound, so he breathed a sigh of relief.

However, the rest of his body, especially on his backpack, could not pass the level, and kept beeping.

And it's not just him, everyone else has more or less some metal products on their bodies, mecha barrels, battle armor iron pellets, weapons, etc., and even the buckles of backpacks.

But everyone didn't have much emotion, would the person who was a mercenary have no metal products on him?

After removing the metal products, they were guided and accompanied by city officials to the department store where they were connected.

This department store is like a shopping mall, you can find everything you can imagine.

For example, there are energy guns, death guns, energy cannons, death cannons, and even space mechs that can travel in space, and of course, most of them are metal products.

It's just that if you really want to find items that don't contain metal, it's not that you don't have to, but you have to spend some energy to find them, and the four of them are floating around in various shops like butterflies, constantly purchasing the items they need.

In addition to buying some necessities, Li Ping'an also bought a sturdy backpack with no metal at all, even if the backpack is not metal, it can be made quite strong.

And considering that this can be used for a long time, I specially chose a sturdy backpack, and the cost is paid by the city government anyway, and it is not spent in vain.

After everyone had regrouped, Professor Fama and the students went down to the basement of the city hall.

In one of the rooms on the fifth basement floor, when Mayor Kentucky opened the door and turned on the light, some of the students and the four mercenaries were stunned, except for a few people who already knew the situation in their hearts.

I saw that on the wall opposite the room, a special hole close to square appeared in the middle of the white wall.

Inside the cave is the scene of another city that is gray and misty.

From the entrance of the cave, it was a straight street, about seven meters wide. There are houses with closed doors and windows on both sides, but what shocked Li Ping'an the most was that the pattern and pattern of this house turned out to be like the streets of Taipei during the Chinese New Year, with businesses with doors and windows closed, and the streets were deserted.

But apart from some fallen leaves, there is no other garbage on the ground. This is far worse on the streets of Taipei.

And there seems to be a soft light in the sky, so you won't lose sight of your fingers inside.
