Drilling into the ground is not a new thing in the cultivation realm, but there is a difference between speed and slowness, depending on the tools used.

This time he escaped from the ground, and Xiang Yihang really realized how bullish the ancient sword and blue sea were!

Under the transfer of spiritual power, the blue sea was like a super drill bit that rotated at an ultra-high speed, and the rocks in front of it turned into powder one after another, and then it was discharged to the back.

Some people may say that if it's so easy to drill into the ground, isn't it also easy to dig up minerals?

Yes, it's simple, but it's a lot of work!

A Chemical-Free Realm is that big, if it's a super civilization planet, how big is it?

Moreover, not everyone has a super weapon like the ancient sword and blue sea!

The human-level superb flying sword is much slower than the ancient sword Blue Sea.

Moreover, in star fields with more sound laws, such as the ** Luo Galaxy, the rocks will become harder and harder.

Therefore, under the action of multiple factors, mining, like the earth, is still the hardest and most tiring work!

Now, Xiang Yihang is in trouble.

The stones in front of him were a little hard, and the speed of the blue sea slowed down, and it was getting slower and slower.

It's not that Bihai can't cut those stones, but with the support of the same spiritual power, Bihai's drilling speed has slowed down, indicating that the stones in front of him are very hard.

If you want to maintain the same speed, you must increase the infusion of spiritual power.

But this will lead to severe depletion, as the rate of spiritual power recovery is far from keeping up with the rate of depletion.

Xiang Yihang did not change direction, since he encountered a hard stone, it means that there is an abnormality ahead.

Anyone who has ever mined knows that if the well is drilled to a special soil, it probably means that the right mine has been dug at the right site.

So Xiang Yihang wants to see what is ahead, if it is a rare mineral, then he will make a fortune.

He is now almost a thousand kilometers underground, and it will not be too easy for anyone to chase him, and this distance has long exceeded the range of the cutting gun.

So Xiang Yihang was not in a hurry to go out.

He increased his spiritual power slightly, which increased the speed of Bihai a little.

Under the high-speed cutting and grinding of the blue sea, no matter how hard the stones in front of them, they also fell one after another, and under the discharge of Xiang Yihang's spiritual power, the debris continued to squeeze backwards, blocking the pipeline from the rear.

"Whoa!" Suddenly, there was a loud bang, and there was a collapse in front of him, revealing a dark space, and the sound of water flowing.

Xiang Yihang's mind swept in.

"It's an underground river, but there are a lot of unknown milky white stone crystals on the riverbed and top!" Xiang Yihang said in his heart.

He drifted straight in.

This underground river is not very large, with a flow rate of about 10 cubic meters per second.

But the river is cold.

There are some fish and shrimp in the water, but none of them have evolved to the extent that they can use aura, and they are no different from the creatures of the earth.

Xiang Yihang went upstream.

There were a few milky white stone crystals in front of him, and he rolled up his divine power and them in his hands.

These milky stone crystals are round in shape, the size of an egg, and seem to contain a lot of energy inside.

"It should be the same attribute as the energy crystal!" Xiang Yihang said in his heart.

He ran the exercises and tried to refine them.

As soon as he refined, Xiang Yihang showed a look of surprise.

After experiencing it for a while, Xiang Yihang determined that this kind of milky white stone spar was completely different from the beast core and the sixth-level energy spar, but it had the same effect as the soul crystal, and the refined spiritual energy could be immediately absorbed by the body, and the consumed spiritual power could be replenished immediately.

"Could it be that this is the legendary spirit stone?" Xiang Yihang's mind flashed.

He immediately checked the storage belt he had stolen from the green-skinned man again, and sure enough, there were hundreds of the same milky white hedrons, only of different sizes.

The big ones were as big as the milky white stone hedron he had on hand, and the smaller ones were the size of his fingers.

These hedrons were harder than the hardest rocks before, and they presumably compressed a lot of aura in them.

"Spirit Stone! Haha! Sure enough, blessings and misfortunes depend on it, and misfortunes and blessings depend on it! I, a rookie cultivator, can unintentionally bump into the spirit stone, all thanks to the persecution of those two aliens!" Xiang Yihang laughed in his heart.

Indeed, if it weren't for the pursuit of those two people and their technological weapons, he wouldn't have gotten into the ground.

If you don't burrow into the ground, you will definitely not be able to come here, and you will not be able to get the spirit stone.

Although the storage belt he robbed also had spirit stones, he was in too much of a hurry to check it at all.

If he hadn't found it today, he didn't know when he would have discovered that he also had hundreds of spirit stones on his body!

Xiang Yihang accelerated and walked upstream, and infiltrated his divine thoughts into the riverbed and the rock layer above his head, and once he found the spirit stones, no matter how big or small, he dug them all up.

Xiang Yihang stopped and found that the space in front of him was slowly narrowing.

He was eager to see what the end was like, and he was speeding forward.

The front grew narrower and narrower, and at the end there was only a hole in the water that gushed like a sprinkler.

Xiang Yihang infiltrated his thoughts along the river, but he couldn't see the end.

The obstacle to the divine mind is still obvious.

Along the way, Xiang Yihang has picked up fifty or sixty egg-sized spirit stones, but no one will have too many of them.

Moreover, he will find a way.

Xiang Yihang tidied up for a while, opened the aura hood, and then dived into the water, swimming upstream.

The narrow waterway causes the current to be very fast, but for the monks in the infancy, it is not difficult to swim against the current.

The whirlpool formed by spiritual power pushed Xiang Yihang to move quickly along the river like a swordfish.

After swimming along the winding river for more than an hour, Xiang Yihang found that the river began to slope downward.

But he didn't think much of it, and kept diving down the river.

The river is strange, round, and has a smooth inner wall, like a pipe produced by modern technology.

However, the material that makes up the river is very hard, and Xiang Yihang's superb flying sword cannot be crushed.

The ancient sword and blue sea can be crushed after using enough spiritual power to stimulate the ancient sword pattern, but it is very difficult to dig a big hole, and it takes too much.

Therefore, Xiang Yihang's only way at present is to keep going along the river, or retreat to the place where the riverbed was found.

Xiang Yihang naturally did not choose to retreat, but continued to follow the river to sneak down.

You, you, Xiang Yihang was numb, he didn't know how long it had been, he guessed that at least ten days and ten nights had passed.

During this period, he was refining the beast core while sneaking, although the speed was nearly half slower than speeding in the air, but in ten days and ten nights, at least seven or eight million kilometers of sneaking.

But there is still no end in sight!

"How big is this incarnation realm? It is only more than 40,000 kilometers around the earth, and only 380,000 kilometers from the earth to the moon. And here, there are millions of kilometers at every turn, is this really big, or does it just give people an illusory feeling?" Many thoughts burst out of Xiang Yihang's heart, and he began to doubt the authenticity of this place.

Could it be that this is just a virtual world?

Or is it that the things here are magnified countless times?

As soon as a thought comes to mind, it quickly spreads like a virus!

At this time, Xiang Yihang's mind was full of doubts about the authenticity of the Wuhua Realm!

But doubt is doubt, whether it is virtual or magnified, he must finish the road in front of him and solve the trouble.

Either he's most likely trapped here for a long time, or he'll be teleported out all of a sudden.

However, since he thought of this possibility, Xiang Yihang would not easily dilute this idea!

There are too many magic in the cultivation realm, even if this is just a virtual world, or a world that can be scaled up, it is not impossible!

There is a saying on the earth that is true: make bold assumptions, and be careful to verify!

In the following days, we will slowly verify it.

About ten days later, Xiang Yihang's mind suddenly scanned a big lake!

The water of the river flows from that great lake.

"Poof", Xiang Yihang rushed directly out of the water at a very fast speed.

But then, he saw an incredible picture!

(End of Chapter 2, there's something to do tonight, continue tomorrow!)
