Guarding a reservoir? I am guarding the river of time!

A familiar breath came from the coffin.

At this time, at some point, fireflies appeared in the cemetery, emitting a faint green glow, like sparks dotted in the dim cemetery.

The next second, a larger firefly landed on the coffin. With the help of the faint light of the firefly, Su Mu could see the whole picture of the coffin.

A rectangular ice block was placed in the coffin.

The familiar breath that Su Mu felt came from the ice block. This was the river water in the river outside!

However, it had solidified into ice.

Looking closely, you can see that something seems to be frozen in the ice block.

Su Mu picked up the dagger and continued to open the coffin. He opened it about three meters wide and saw the frozen object clearly.

What is this?

A human finger?

Judging from the appearance, it should be the index finger of the right hand, as long as a normal human, but the flesh and blood wrapped in it have disappeared, leaving only a piece of index finger bone.

The bone coffin contained an ice coffin, and this huge ice coffin contained a human finger bone that was only eight or nine centimeters long, which created a visual contrast.

Going through so much trouble, just to bury a finger bone?

At this time, Su Mu stretched out his hand, and the moment he touched the ice coffin, he was sure that the water that had condensed into ice was the water in the river outside.

Because Su Mu had been guarding the river for so long, judging by his affinity for the river, he would never make a wrong judgment.

Then, Su Mu took out a dagger and prepared to cut the ice coffin, but no matter how he cut it, it was useless, and even no trace was left.

This made Su Mu confused.

How did his silver dagger encounter two things that he couldn't cut today?

The key point is that this is an ice coffin, there is no reason why it can't be cut!

Su Mu stretched out his fist and smashed it at the ice coffin. He smashed dozens or hundreds of punches, but there was no trace left.

At this time, Su Mu used his water control ability and found that he couldn't move it.

He grabbed a corner of the ice coffin and weighed it. It was more than a thousand pounds. It was estimated to be two or three thousand pounds.

No wonder, Su Mu's current water control ability can only control one thousand pounds of water.

But the strange thing is that even if it is two or three thousand pounds, let alone he is already in the human fairyland, even the young man who has just practiced Taoism can carry two or three thousand pounds of weight, and some slightly stronger mortal warriors can withstand this weight.

But he himself, can't carry it?

This made Su Mu start to doubt whether he was a fake fairy.

This ice coffin is weird, yes, it must be a problem with it, not himself.

His [magic ability] to control water includes peeling, acceleration, stillness, and retreat.

But it can't melt this ice coffin that has already turned into ice.

Su Mu ran the skills, and the majestic spiritual power burst out from the palm of his hand, turning into a scorching spiritual fire to wrap the entire ice coffin, but after roasting for an hour, there was no sign of melting.

It can't be cut, hammered, or burned. There's really nothing he can do.

In desperation, Su Mu could only give up this tombstone.

Anyway, there are so many here, and it's not necessary to hang on this tree.

Su Mu checked every corner of the coffin and found no burial objects. He jumped off the grave without interest.

After searching, Su Mu set his sights on the next grave.

But before digging, he took out three incense sticks from the space ring, lit them, and inserted them in front of the tombstone, then slowly said: "Excuse me, excuse me."

After that, he started digging with ease. With the experience of the first time, Su Mu dug smoothly the second time and found the right position.

People are like this. They can't find the right position the first time, and even find the wrong position, but the second time is fine, and they are familiar with it.

This time, the coffin was dug in ten minutes.     It is exactly the same as the last coffin dug, also a white bone coffin, and also a bone coffin made of cervical vertebrae.

According to the previous method, first use the silver dagger to make a big hole, and then pry it open with force.

After prying it open, Su Mu's pupils shrank slightly and his eyes were stunned.

Like the previous one, the bone coffin is still an ice coffin.

But the only difference is that the toes are frozen in this one, or to be more precise, the thumb.

At this time, Su Mu thought of something.

He quickly dug the third tombstone, and after digging it out, it was also the same structure, and the frozen object turned into a rib.

He dug the fourth, fifth, sixth, and tenth.

They were all teeth, fingers, forearm bones, thumbs, and other human organs, and they were all different!

Su Mu sat on the tombstone and began to ponder. A bold guess emerged in his mind.

These three thousand tombstones may not bury three thousand people, but the same person!

He guessed that if all these three thousand tombstones were dug, those organs would be combined together to form a complete body of a person.

However, Su Mu didn't have the time and energy to dig all of them.

It doesn't look tiring, but digging is really exhausting, and you will feel inexplicably tired. After digging only ten, Su Mu was already panting with exhaustion.

The most important thing is that it's tiring, but there is nothing to gain, which is very annoying.

At this time, Su Mu suddenly thought of something, so he flew into the air, stood in the void, looked down, and had a panoramic view of the entire cemetery.

After a careful look, he felt that the shape of the cemetery was very similar to a pattern, but he didn't know what the pattern meant.

The most important thing was that the arrangement of the three thousand tombstones was also very strange, like a formation arrangement.

Although Su Mu didn't understand the formation, he sometimes read some ancient books on ancient formations when he was bored.

Su Mu felt that the cemetery was a large formation, and the tombstones in it were the center of the formation. He didn't know if his guess was right, but he had this feeling inexplicably.

At this time, he noticed a tombstone located in the upper right corner of the cemetery.

This tombstone was ten meters away from the other tombstones, while the other tombstones were exactly nine meters apart. The subtle difference of one meter certainly didn't escape Su Mu's eyes.

After locking onto this tombstone, Su Mu landed on the ground.

When he came to this more special tombstone, he found that this erected tombstone was a circle larger than the surrounding ones.

He climbed up the tombstone and started digging.

After digging for almost five meters, the coffin was not found. The deepest tombstone was basically found after digging three meters.

Su Mu continued to dig down, and when he reached about ten meters, he finally found it.

Hmm?

What caught his eye was not a huge bone coffin, but a square black wooden box with a side length of about half a meter.

My analysis was correct, this tombstone was indeed special.

Unexpectedly, Su Mu opened the wooden box easily without using any means.

"What is this?"

Su Mu frowned.
