Underwater, except for the light source given to Li Hugo by the searchlight, there was nothing else to light up, so the eyes were also blurry.

When Li Hugo entered the cave, he immediately opened his eyes, and sure enough, he found that under this wine spring, the aura was very abundant, which was like a level of aura division, the more he went to the water, the thinner the aura became, but in fact, the aura under the water was quite sufficient.

It's just that the bottom of the water is more than fifty meters away from the surface of the water, and the water pressure below is also quite large, as strong as Li Hugo, and he even felt a burst of pressure.

Because of the pressure of the aura and the pressure of the water, the pressure here is much stronger than the ordinary sea area, Li Hugo initially estimated that the water pressure here is probably a hundred times the ordinary water pressure, after all, the pressure of the aura is considerable.

Air pressure is very common, in the modern world, many are using the principle of air pressure, such as syringes and pumps, and similar to air pressure, the use of water pressure can be very labor-saving, but the use of bad may bring negative effects Moreover, water pressure is not as weak as people seem.

Li Hugo saw with his heart that the surrounding aura turbulence came from the cave, that is, the aura flowing out of this inconspicuous underwater cave was partially dispersed to the surface of the water through the water flow.

He grabbed the entrance of the cave with water pressure, but at this time, a strong flow of water suddenly blew out from the entrance of the cave, like an underwater bomb, almost blowing Li Hugo away, and he finally grabbed the rock wall to stabilize his body.

However, the rock wall is very smooth, like pebbles that have been polished countless times in the stream, and it is impossible to start.

Li Hugo waited at the entrance of the cave for ten minutes, and his arms were already sore and unbearable, after all, the double pressure of water pressure and water flow did not make people too comfortable.

When the water stopped, Li Hugo burrowed into the hole, which was very narrow, only half a meter long and wide, and the surrounding rocks were raised, although it did not cut through the diving suit, but it was also quite difficult to dive in.

Don't look at this is just a small dive, if Li Hugo drinks a sip of Jiuquan water, I'm afraid he will not be able to bear it, after all, the spring water in Jiuquan is close to 100 degrees of alcohol, the taste of wine is very medium, the water surface at the top of the water Jiuquan is good, it is estimated that the alcohol content is only about 50 degrees, but now under the water, this Jiuquan is already close to 100% alcohol content, and there is aura in it, and you will get drunk if you don't take a sip.

Although Li Hugo is a cultivator, he is not a god, he also needs to breathe, if he is drunk and falls unconscious underwater, once he is suffocated, he will definitely die.

After a difficult crawl, Li Hugo passed through the long and tasteless underwater passage, and finally followed the direction of the aura to the exit.

Heart's eye was a great help.

Li Hugo came to the end of the cave, but found that this was a broken gate, this underwater stone door, very strong, very strong aura, from the crack of the stone door continued to flow out.

Li Hugo pulled out the Blue Water Cold Knife and stabbed it into the gap, relying on the characteristics of the Blue Water Cold Knife, it was able to freeze the water.

In general, the object obeys the thermal expansion and contraction, that is, for the same object, the density of the solid should be greater than that of the liquid, but the water is the opposite, this reason involves chemistry., because the water molecule is a very polar molecule, can be combined into an association molecule through hydrogen bonding, the liquid water molecule occupies a relatively small space, at this time the density of water is the largest, but the water freezes, When water freezes, almost all the molecules associate together to form a huge association molecule, and this arrangement leads to an open structure, that is, there are large voids in the structure of the ice, so the density of the ice is inversely smaller than that of water at the same temperature.

Taking advantage of the swelling of this ice, Li Hugo swelled the water in the gap, although there was alcohol all around, but Li Hugo's ring was worn on his hand, so while letting the gap freeze, he took out a bottle of mineral water and nourished it inside.

In this way, alcohol is avoided and the gap is constantly widened like a hydraulic press.

"Click!"

There were really more gaps, and there was a crack around it, and Li Hugo kicked it, and the stone gate had been shattered.

It's not that Li Hugo is stingy with vitality, but because Li Hugo's skin can't touch Jiuquan, and the skin can also absorb liquids.

Stepping on the stone door, Li Hugo swam in, and found that below this, there was a rather spacious underwater space, he was interesting towards the water, which was like a "U" shaped letter, the front section was connected to the exit of Jiuquan, that is, the entrance to Jiuquan of the outer door, and the rear end of the led to another underwater hole.

Li Hugo floated to the surface, he took off the hood on his head, smelled the air, he began to cough loudly, he found that the aura here is rich and terrifying, and a large mouthful of aura poured into his nasal cavity as soon as he breathed, just like eating a chili pepper, so that he choked on tears and came out.

Looking around, Li Hugo found a river beach, and on the river beach was an altar, and this altar actually had a white bead on it.

Li Hugo took out a wine barrel that had been prepared in advance, because he had prepared all this, the barrel was filled with pure water, and he put the white beads into it.

In the blink of an eye, the pure water turned into a barrel of liquor, Li Hugo dipped a little bit with the tip of his tongue, and his face suddenly changed, this wine is full of aura, and the wine taste is charming, it is simply a rare wine.

And this white bead can turn a bucket of water into a bucket of wine in a second, which is simply an existence against the sky!

This is an absolute treasure!

Li Hugo was happy in his heart, knowing that he must have picked up the treasure, just take this bead away, I'm afraid that this Jiuquan will be invalid after a while, but in fact, Jiuquan is also quite chicken for the outer disciples, the food is tasteless, it is a pity to abandon it, and taking it away by yourself can also force the outer disciples to use conventional methods to cultivate, instead of blindly looking for shortcuts.

Thinking of this, Li Hugo put the "wine pill" into the ring, he checked everywhere again, and found that there was a corpse in the distance, this corpse looked quite old, it had already become moldy, Li Hugo walked in and saw a sword next to the corpse, and some belongings.

Most of the items are useless, but this sword is still very clean, and it is a good sword.

"Drunken Sword. Li Hugo saw two big words written on the wall.
