"What is this?" The case was about the size of a normal suitcase, covered in dust, and looked like it hadn't been touched in a long time.

"This is what can prove the existence of the Silent Realm," the old man slowly opened the box, "The old master has been searching for the secrets of this Silent Realm all his life, and he is not even married, otherwise he can at least leave some heirs, hey......"

The box was opened, and there was only one thing inside, a stone slab twenty centimeters long, five centimeters wide, and only about one centimeter thick.

The slab is a yellowish-brown color, with different motifs carved on both sides, and on one side is a man wearing a crown, suspended in mid-air, and at his feet are countless prostrated humans and animals.

On the other side of the slab is what looks like a plant, but because it's so abstractly drawn, no one can tell what it is.

"Old man, isn't this just an old slate? Why does it prove the existence of the Silent Realm? Yu Hao asked.

"This is no ordinary stone tablet, this stone tablet was found near the entrance to the Silent Realm!"

"The entrance to the Silent Realm? Where is it? The crowd was excited.

"Legend has it that it is near a strange circle about two thousand kilometers north of the city, but there have been countless people who have tried to find that place, and those people have either returned in vain or mysteriously disappeared, and so far no one has actually found the Silent Realm."

"Strange field circle?" Yu Hao thought for a moment, this should be something similar to the crop circle on the earth, some people once thought that this was a mark of aliens, but after various studies, Luo Xiao gave them an explanation.

This kind of wheat field circle is something similar to formation inscriptions, but these formation inscriptions are not able to drive autonomously, and they require a lot of energy infusion to drive, as for the effect after driving, only very professional people can deduce it, at least Luo Xiao himself has no way to do it for the time being.

"That strange field circle should be the key to drive the entrance to the Silent Realm!" Luo Xiao communicated with everyone in the school's communication system.

"Old man, what does the thing on this slate represent?" Sun Zihan pointed to one side and said, "This should refer to the king and subjects of the Silent Realm, but what is the other side?" ”

"This is the secret of their longevity and strength!" The old man said, "No matter how much it evolves, the history of human beings is still only like this, and if you want to have eternal life and infinite power, you must rely on the power of external objects." ”

"This plant is called 'Gift of the Gods', and my master deduces that the secret of their power and longevity is this plant called 'Gift of the Gods'!"

"Ding Dong, trigger the additional question, find the 'God's Gift' and get a specimen, the task is successful: everyone will be rewarded with 2000 credits, the task is failed: no punishment."

"Actually triggered the additional question!" Everyone was immediately refreshed, but this also showed from the side that the inference of the owner of this museum was correct, and the "Gift of the Gods" must have extraordinary power, otherwise it would not have been possible for the principal to attach so much importance to it.

"I think this 'God's Gift' should have the effect of strengthening physical fitness and increasing lifespan, if we can get it, it should be very helpful to us!" Yu Hao said.

"No, it's not that simple!" Sun Zihan objected, "There has never been a power in the world without a price, don't forget, the legend says that this country was finally extinct, we might as well boldly speculate that this plant gave them longevity and strength, but it also took away something imperceptibly......

"This ......" is analyzed rationally, and Sun Zihan's inference is not unreasonable.

"Looks like you're interested in the Silent Realm!" The old man put the box away and put it back in its place.

"Of course, although we are adventurers, we are also college students, and if our graduation thesis can write about the affairs of this country, it will definitely shine!" Sun Zihan made a fanatical look, which made the old man even less suspicious of their identity.

"By the way, there are still some collections about the Silent Realm on the third floor of the museum, you can visit them yourself, I don't have a lot of legs, so I won't accompany you." The old man seemed to be a little tired after talking for so long.

"Thank you, we'll watch it carefully."

The lights on the third floor seemed to be broken, and Sun Zihan took out a small lamp that illuminated almost the entire floor at once.

The exhibition hall is surrounded by rubbed frescoes, these frescoes are supposed to record the history of this country, they have had wars, there have been famines, but under the leadership of that king, they still walked step by step.

"How old did this king live, you say?" The frescoes here are arranged in a chronological line from beginning to end, but the image of the king has not changed in the slightest.

"Maybe a few thousand years old!" At the end of the mural, the king is lying in a delicate coffin, as if his life has come to an end, and it is not as eternal as the legend suggests.

"Why does the history of the Silent Realm end here? Is there no one to succeed to the throne after the death of the king? The crowd wondered.

"It seems that these secrets will have to be revealed only when we find this kingdom."

"Bang!" Just as everyone was using their brains to their heart's content, a gunshot rang out from downstairs.

"Someone!" Yu Hao was the first to react, he rushed downstairs in two or three steps, the kind old man had already fallen in a pool of blood, and there was a bleeding bullet hole in his chest.

"Xu Yun! Xu Yun! Come and save people! Yu Hao blocked the wound and shouted, the bullet didn't hurt the heart, the old man should still be saved!

"Box...... There......" The old man pointed with difficulty to where he had stored the box.

"Yes, the box!" Yu Hao immediately opened the cabinet, and the box inside was indeed gone, and someone actually wanted to snatch the slate!

At this time, Xu Yun and the others finally came down, although the old man was old and his body was not so tough, but fortunately, the bullet did not hit the vital point, and Xu Yun's medical skills were very comparable, and the injury quickly stabilized.

"They can't be allowed to take the slate...... They...... The tablet was the key to the coffin of the Emperor of the Silent Realm," the old man pulled out a roll of blood-stained parchment from his clothes.

"This is the last thing the old master confessed, he said that the king must not be reborn, otherwise the world will be destroyed......"
