I don’t know if it was because they wanted to protect the newcomers, or if the real purpose of Lin Yuan and the other two being sent here was not the ruins, but just to let An Xueyi find out their background, or if it was because of the gradually stiff conversation tonight.

Although Lin Yuan and the other two did not have much time to explore the secret realm, and today only made up three days in total, An Xueyi did not arrange for the three to enter the ruins directly due to the tight schedule. Instead, he asked them to have a good rest tonight and wait until tomorrow to discuss everything.

After Lin Yuan and the other two went upstairs, they could still hear the conversation that An Xueyi tried his best to suppress, but still could be heard clearly by the three of them.

"Xiaoxiao, how can you be so rude today?"

"President, don't you think these three are weird? They're hiding a lot of secrets, but they're still putting on an act in front of us!"

"Xiaoxiao, you were indeed too impulsive today." Zhou Yuan sighed and joined the conversation: "Those three kids are not cunning people. They are only seventeen years old. There is no need to think too badly of them."

"What are you talking about?" Liu Wei looked confused and said, "I think those three kids are pretty good, but the one named Su Mu cries too much. How can he shed so many tears? I'm a little worried that he might be dehydrated."

Zhao Xin said: "I agree."

"Oh, can't you see that those three people have bad intentions?" Yun Xiaoxiao raised her voice: "Especially that Lin Lang, he doesn't look like a good person at first glance!"

"Xiaoxiao!"

"President, I'm your teammate, how can you speak for them!" Yun Xiaoxiao looked very angry: "You are not attracted to that Lin Lang, are you? She is just a pretty vase, how am I not as good as her!"

"Xiaoxiao, don't go too far! How could I like a seventeen-year-old girl! What I like is... is..."

"President?"

"Anyway, we are a team now. Put away those weird ideas of yours and just focus on the mission!" After saying that, An Xueyi obviously didn't want to get entangled with Yun Xiaoxiao anymore and fled away from the living room.

Lin Yuan and Lin Lang, who were eavesdropping in the room upstairs: "......"

The two of them turned to look at Su Mu in unison, with teasing looks in their eyes.

Su Mu: "...What are you looking at!"

...

Some people stayed awake all night, while others tossed and turned. Only Lin Yuan and the other two had the same sleep quality as always - no matter when or where, as long as they lay down on the bed, no matter how early they went to bed, they could not escape the curse of staying in bed.

When An Xueyi and his group had packed up and were ready to leave, Lin Yuan and the other two came downstairs yawning.

Even after a night, Yun Xiaoxiao's hostility towards Lin Lang and the other two had not dissipated in the slightest. No one knew where she got so much enthusiasm from.

Seeing that Lin Lang looked like he hadn't woken up yet, Yun Xiaoxiao sneered. Just as she was about to mock him, she remembered An Xueyi's scolding yesterday and restrained herself a little. But she couldn't help but said, "You guys really are here for vacation."

"It's okay, we can leave now." Lin Lang rubbed his eyes and said, "High school students can go out just by kicking off the quilt."

Yun Xiaoxiao: "...There's no breakfast for you!"

Lin Lang still looked sleepy, but he spoke sweet words without hesitation: "It doesn't matter. As long as I can see you, my day will be full of energy."

Yun Xiaoxiao: “…”

She stamped her feet and left the house angrily.

...

The ruins were very close to the courtyard where Lin Yuan and his friends lived. After walking along the path and passing a few courtyards, a huge pit could be seen. It was surrounded by cordons and white tents, leaving only the only entrance and exit equipped with a security gate.

Most of the people near the pit were wearing white protective suits that covered them from head to toe, with watches like monitors on their wrists. They hurriedly shuttled back and forth between the ruins and the white tents, dragging a large tray in their hands, which was filled with something wrapped in loess, whether it was bones or stones.

Except for these men in white, the rest, like An Xueyi and others, wore mountaineering clothes and boots suitable for going down to the ruins and convenient for exercise and combat. They carried weapons on their waists or backs, ranging from big swords and magic staffs to professional guns. There was a wonderful feeling of the fusion of the Western fantasy world and modern science.

The only thing in common is that they also wear watches on their wrists for monitoring.

"This is a personal ID, and it is also a device for detecting heart rate, brain waves, and magic power concentration."

After passing through the security checkpoint, An Xueyi handed three IDs to Lin Yuan and the other two, motioning them to take them with them: "It is also equipped with a GPS positioning system. If you are separated from us and trapped in the ruins, immediately click the distress button on the ID. Everyone will receive the distress signal you sent and quickly approach you."

With heart rate monitoring and GPS positioning, even before they went down to the ruins, Lin Yuan and the other two could guess that the danger level underground was quite high.

"Why don't we have to wear clothes that look like protective clothing?" Su Mu asked curiously.

Facing Su Mu's question, An Xueyi explained very patiently: "There is powerful magic in the ruins. For those of us who can absorb magic and use magic, the higher the concentration of magic, the more suitable it is for us to practice. But for ordinary people, high concentrations of magic are more likely to cause mutations. In order to prevent any accidents from happening during the exploration of the ruins, they chose to use protective clothing to isolate all contact with magic."

Su Muxin wondered if this thing was really useful, and couldn't help but glance at An Xueyi.

Just talk, why do you have to lean towards him?

Fortunately, An Xueyi was a very restrained person and did not show any abnormal behavior outside. Seeing that Su Mu was a little uncomfortable, he quickly distanced himself from Su Mu and returned to his previous polite appearance: "Follow us later, and don't run around. Do you understand?"

After Su Mu and the other two nodded, indicating that they would absolutely be obedient, An Xueyi nodded with satisfaction, and led his team members to encircle them from the front and back, sandwiched the three of them in the team, and went down the cave through the simple elevator.

Unlike the green mountains and clear waters outside the cave and the beautiful scenery, the inside of the cave is a world of its own.

Rather than a cave or cemetery, this place is more like a half-collapsed castle, surrounded by the most common stone pillars and arches in Western-style buildings. Due to its age, the stone pillars have been severely worn, but if you look closely, you can see the fine carvings left on the stone pillars. The only natural light source comes from the huge opening above the head. The Tyndall effect makes the sunlight look like a straight waterfall, and the dust floats around the light like elves, adding a touch of romance to this somewhat strange relic.

How could there be a Western-style castle hidden beneath a standard Chinese county town?

Lin Yuan looked around - such a large space, this was just the range they could see, it was already equivalent to a small manor. According to the direction of the space extension, even the village where they were temporarily staying was built on the ruins.

The personal ID worn on the right wrist was changing numbers frantically: This was the concentration of magic in the ruins. From the cave entrance to the bottom of the ruins, which was less than 20 meters away, the concentration of magic had increased by a full 50 times, only slightly lower than the concentration of magic in Class 9's classroom.

Magic power is not like air. Hot air rises and cold air sinks. It freely roams between heaven and earth, going to every place it wants to go. Even if it is blown away by the wind, it can quickly gather. According to common sense, with such a huge hole, the magic power accumulated in the ruins will definitely fly out of the hole and spread out quickly. However, all the magic power abnormally accumulated in the ruins, continuing to grow thicker and thicker.

——More importantly, the concentration of magic here far exceeds the normal concentration of magic on Earth today.

There is only one way to explain it: there is a "Spirit Gathering Array" under this secret realm. It is even very likely that a considerable amount of magic power has been stored in this relic long before the magic power revived.

Lin Yuan and the other two could feel that the magic power from the outside was just the tip of the iceberg that seeped out of the ruins; the things inside the ruins were the real bulk.

It seems that their understanding of the Earth is still too superficial. They only focus on the magic and mutants that are pouring into the Earth, but never consider that there may be relics of magic hidden beneath the ground they are standing on.

However, the style of the ruins is not traditional Western architecture, but a very distinctive Parnacian style. Regarding this, I believe those "time travelers" have already noticed it and reported it to the authorities.

Lin Yuan and the other two exchanged glances silently and decided to follow An Xueyi and his group forward to see if there were any special circumstances.

"I originally thought it was just an ordinary secret place." Lin Lang said, "Now it seems that things are much more complicated than we imagined."

"Me too. I wanted to hang out with this group of "travelers" and see what they are capable of." Su Mu sighed, "Now I just feel that from the official to this group of "travelers", they are all courting death... There is even a spirit gathering array, who knows what incredible things are imprisoned in it."

Lin Yuan agreed: "I doubt they even know what a spirit gathering array is."

"Su Mu is in your hands." Lin Lang urged, "Help us get some information out of this guild president!"

"Why me?" Su Mu was full of questions, but he never had much say in front of Lin Lang, so he could only accept the task sullenly and lean towards An Xueyi.

"Um, President An..."

An Xueyi immediately showed an expression of being flattered: "Don't be so polite, if you don't mind, just call me 'Big Brother An'."

Su Mu: “…”

Su Mu resisted the urge to roll his eyes, and said in his heart: Then you should call me Master Su. On the surface, he still maintained a pure and innocent look, blinking his big watery eyes, pretending to be curious: "Why is the concentration of magic power here so high?"

An Xueyi shook his head. When talking about serious matters, he quickly returned to a professional attitude: "We haven't investigated this point clearly yet. What is certain is that this is the place with the highest concentration of magic power in the world so far."

Then you haven’t seen our school, otherwise you would be scared to death.

Su Mu complained in his heart and said, "So the authorities called us here..."

An Xueyi smiled at him and said, "That's exactly what you thought. You might want us to practice here."

Such a strong magic power would be wasted, but the place is so small and full of dangers, and there is no guarantee whether staying in the strong magic power for a long time will affect the "travelers". Therefore, except for officially recognized "masters" like An Xueyi, most "travelers" will not stay here for long.

As they were talking, the group finally arrived at the real destination of this trip - a huge door at least thirty meters high hidden behind the "castle".

I don't know what material the door is made of. From a distance it looks like marble, but when you look closer you realize it is some kind of metal. On both sides of the door are lifelike carvings that look like Western dragons, as if the dragons on the totems will open their eyes at any time, spread their wings and fly out of the door.

All kinds of "time travelers" and staff members are gathered at the gate, trying to push the door open or using instruments to detect the metal composition on the door, and they are very busy.

Lin Yuan and the other two: "......"

"Am I dazzled?" Su Mu murmured, "Why do I seem to see...Song Mingzhe's uncle?"

"...You're not mistaken." Lin Lang also fell into a daze: "The one next to him is his uncle."

Lin Yuan: "Song Mingzhe! Your ancestral grave has been dug up!"
