One attribute point per second, I am invincible!

Lin Mu returned to the place where the spirit coins were placed.

He couldn't remember the specific location of the spirit coin in front.

However, when he placed this spirit coin, he deliberately pushed the spirit coin in a little bit.

However, when he wanted to find the small hole that the spirit coin had been pressed into, he found that he couldn't find it no matter how hard he looked.

"It's obviously at this location, why can't I find it?"

He used his vitality to search the area carefully, but could not find any relevant traces.

"Something's wrong, something's wrong with the ground here!"

Lin Mu searched carefully two or three times and finally found something unusual.

He found that there were no footprints wherever he walked!

Moreover, when he looked at the footprints, they were there, but when he turned his head, the footprints disappeared.

The same principle applies to using vitality sensing. He uses vitality to cover the footprints, and the footprints are there.

Once the vitality is withdrawn from the body, the footprints will disappear immediately.

"Strange! There seems to be something here that's been watching me! As long as I feel it, whether it's my five senses or my vitality, he won't make any move!"

"Once I stop observing, all traces I leave will be erased!"

"The law of time?"

Lin Mu held a handful of soil with his hands and found nothing unusual.

He wondered if it was because of the law of time. Only the law of time could erase all traces.

But he couldn't understand why the law of time erased his traces when he couldn't sense it?

"Then let me see what's under the ground!"

After thinking for a long time, Lin Mu didn't understand, so he directly used his vitality to explore underground.

It was this move that made Lin Mu realize that his guess was right.

The Yuan Qi probed down less than one meter when it was blocked by a mysterious force, making it impossible to probe further.

So, he turned on the violent mode.

Yuan Qi burrowed into the ground crazily, and all the land around one kilometer was lifted up by him.

"At this!"

Lin Mu suddenly saw a flash of light, which was his lost spirit coin.

This spiritual coin has actually reached twenty meters underground.

He stood in the middle of a twenty-meter-deep pit, holding a spiritual coin in his hand.

As soon as he left the pit, he turned his back to the pit to recover his energy, and then turned back instantly.

When I turned around, I saw that half of the pit had been repaired, and it was now less than ten meters deep.

The moment he looked back at the pit, the pit stopped repairing.

"Haha! Interesting!"

Lin Mu looked at the big pit with interest, but there was no movement in the big pit due to his vitality.

Now he was sure that something in the Quiet Place was definitely watching him, or monitoring him.

"Just let me see what the hell is under this ground!"

Lin Mu snorted coldly.

The barrier above the Quiet Place was a space barrier, but the energy below the Quiet Place was an energy he had never seen before.

This energy is not only blocking his vitality, but also repairing the ground.

It's possible that it's this energy that's monitoring him.

Now, the only way is to use the vitality to dig down. No matter how deep the place of silence is, we must dig down.

Under the ground is the only unusual place, perhaps the only exit.

It is obviously unrealistic to fly out of the Silent Land.

He doesn't know how big the Silent Land is. He will lose his way after 200 million kilometers, so he can't fly out at all.

And he suspected that there was a power in the Quiet Place that made him spin around in space.

If it is just a single swallowing spirit coin, it will be marked by a triangular arrow, and it must be walking in one direction.

However, he has flown a distance of 20 trillion kilometers and has not yet flown out. This is abnormal.

There are only two possibilities. One is because the space in the Quiet Place is folded, and it may fold once after hundreds of millions or billions of kilometers.

In other words, unless the spirit coins can be continuously connected into a line, they will spin in the folding space.

After flying billions of kilometers, he returned to the original space, in an infinite loop.

There is another possibility that the power monitoring him is changing the direction of the spirit coin arrow.

Because as long as the arrow of the spirit coin always points in one direction, even if the spirit coin in front disappears, Lin Mu's direction will not change.

For more than a month, Lin Mu spent millions of energy and still couldn't get out.

The remaining vitality cannot last long, and even if there are spiritual coins to replenish the Ten Thousand Dao Rings, the 800 million spiritual coins cannot last long.

The senior brother gave him a total of 200 million spiritual coins, and Mu Xing spent 10 million spiritual coins.

He has no property, so he only has these one billion spiritual coins in his possessions in the past ten years.

Just do it. Although digging the ground consumes more energy, Lin Mu does not believe that the land in the Quiet Land is hundreds of millions of kilometers thick.

The largest planet has a radius of only about 200 million kilometers.

A week later, Lin Mu felt the distance between his location and the ground and frowned.

He has dug down 100 million kilometers, and his energy has been consumed by more than 10 million. During this period, he also used spiritual coins to replenish his energy.

However, the ground was still not dug through.

Once the depth exceeds 200 million kilometers, the hole in the ground will be repaired because there is no vitality to cover it.

When the time comes, he will be lost underground, just like he is on the ground.

And the deeper he digs, the more vitality he consumes. He needs to transport all the soil to the ground, otherwise his vitality will be blocked by the energy in the soil.

However, Lin Mu also discovered something unusual.

The land in the Quiet Place is all dirt, not a single stone.

The soil is very soft, and I don’t know how it came together.

Three days later, something hard blocked Lin Mu's way.

"Hey! What the hell, stone doesn't look like stone, and metal doesn't look like metal!"

Lin Mu stopped, cleared away the surrounding soil, and took out a pile of spiritual coins to illuminate the entire underground space.

Below, there was a dark barrier blocking his way.

He didn't know what material the baffle was made of, nor how big it was. The area he dug wasn't very big, so he could only see a little bit.

He expanded the underground space a little and found that there were still such barriers around it.

Lin Mu knocked on the black baffle blocking the way with his hand, and the baffle made a dull tapping sound.

"solid?"

It didn't look like it was hollow below, and the baffle blocked all his energy.

He didn't know what was under the fender, but the special lines on the fender attracted his attention.

He noticed that there were strong lines on the baffle, which were like the annual rings of trees, growing out in circles.

"Why do I feel like I've seen this thing before?"

Lin Mu frowned. These lines looked familiar to him, but he couldn't remember where he had seen them before.

"Try to see if you can penetrate it!"

He thought for a while, but didn't expect what it was, so he directly used his energy to drill holes in the baffle.

The vitality formed a spiral, going down crazily.

"it works!"

Lin Mu watched as the vitality drill bit drilled a small hole in the baffle, and the vitality in his body came out even more crazily.

He had a hunch that there was definitely a secret to the Quiet Place down here, and maybe the exit was down there.
