Chen Fei has no intention of going to Changshengtian for the time being, so naturally he will get the benefits first!

Naturally, he was also interested in the treasures of the Black Sea, but he didn't show it!

Obviously, the three of them were all on guard against Chen Fei, afraid that Chen Fei would rob them, and they must have the means, after all, they are people from a high plane, although their cultivation is not very high, but they definitely have amazing strength!

The group of four galloped through the sky, and after ten days, they entered the shore of the Black Sea.

On the shore of the Black Sea, there are treasure hunts and stone hunts all year round, because all the black crystals come from the depths of the Black Sea and are blown by the waves, and the black crystals are particularly precious, so people come and go on the coast.

Legend has it that the Black Sea cannot be dived, because not only is it buoyant, but there is also great danger in the depths of the sea, and even the sea water in the depths of the legend is poisonous.

The Eight Great Gods have been to the Black Sea of Yin City, but they are not allowed to enter, so they can only return in a huff.

Chen Fei followed the three of them and flew all the way to the end of the sea level, and it took a month for the group of four to reach the target.

There are no landmarks here, and Chen Fei doesn't know how the three of them are sure that there is a treasure here.

But he didn't ask, but jumped into the sea with the three of them.

There was no visibility in the sea at all, nothing could be seen, and divine thoughts could not be released, if it wasn't for Yang Zhen handing over a rope, Chen Fei wouldn't know which direction to swim!

The three of them seemed to be familiar with the road, and they all grabbed the rope and dived all the way.

When he dived to about 300 meters, Chen Fei obviously felt that the buoyancy was getting bigger and bigger, and the speed of the dive slowed down.

And just after the speed slowed down, the old blacksmith suddenly shouted: "Hurry up!" After speaking, a pulling force came, and then a group of four people seemed to be tied to the iron and quickly went down!

I don't know what the old blacksmith did, but in short, the speed has slowed down!

When he dive to about a thousand meters, the Medicine King suddenly handed over a black pill and said, "Put this in your mouth, the next 1,000 meters of sea water will be highly poisonous." ”

Chen Fei quickly took the pill in his mouth, and at the same time, he also found that there was a sizzling sound all over his body, and the seawater was like sulfuric acid, and it actually penetrated into the skin, and even the defense was destroyed in an instant!

Fortunately, thanks to the pill, the group of four people was safe and sound.

After two thousand meters, the buoyancy of the sea increased again, and the speed slowed down again, and the old blacksmith took out another object, and continued to speed up!

After repeating this more than a dozen times, when he almost dived to the bottom of the sea for twenty or thirty thousand meters, Chen Fei heard a 'bang' from under the seabed, and then the four of them also fell.

There is mud on the bottom of the sea, which is particularly uncomfortable after falling, and the current at the bottom of the sea is very strong, and the four of them are like duckweed on the bottom of the sea, if there is no rope, all four of them will have to be washed away.

At the same time, the old blacksmith grabbed the rope and fumbled in the mud paddle, not knowing what to touch.

After touching for more than an hour, the old blacksmith shouted excitedly, "Found it." As he spoke, he didn't know what he had caught, and then he crawled in one direction.

The Medicine King grabbed his feet, Yang Zhen grabbed the Medicine King's feet again, Chen Fei grabbed Yang Zhen's feet, and a group of four people crawled on the bottom of the sea like shrimps.

The undercurrent in the sea was so great that if there was no fixation, the four would have been washed away long ago.

The old blacksmith quickened his pace, and in a moment the four of them had climbed under a reef at the bottom of the sea, which was also like a hill.

The old blacksmith excitedly burrowed into a black hole in the reef, and after the four of them entered, their bodies suddenly became lighter, and then they were able to stand!

There is no water or waves in it, and there is even air and a soft glow!

Someone has been here before, so there's a night pearl on the wall!

The old blacksmith's whole body was shocked, the flames suddenly rose, and Chen Fei also had a little strength to dry his body.

It's a cave, and I don't know where it leads.

At this time, Yang Zhen smiled: "This hole is not long, only a hundred miles, but there are formations along the way, but most of the formations have been broken by us, and there are only some that cannot be broken, but they can also be passed!"

"Oh, okay!"

"Keep up with us!" the three of them finished speaking, and quickly rushed towards it, extremely fast!

Chen Fei followed unhurriedly, he didn't expect that there was a hundred-mile-long cave here! At the same time, he was also secretly surprised how these three people found this place?

Since most of the formations had been broken, they didn't waste much time, and everyone walked to the end of the long cave!

"Is it a door, an iron door, and a layer of ice?" Chen Fei saw the situation at the end, it turned out to be an iron door, no windows, no locks, very tightly sealed, and it was impossible to tell whether it was open inside or out. And there is a layer of ice crystals on the door!

"That's it!" Yang Zhen said at this time: "The reason why we can't open this door is that this door has a layer of cold ice, and the ice defense is extremely strong, and no flame can melt, but the fire of eternal life should be okay, Xiaoyou can give it a try!"

"Will there be an automatic attack?" Chen Fei worried!

"No, we tried attacking the ice, but it didn't bounce back!" The three of them were a little anxious, because they were only one kick away.

"Then I'll try it, but I said in advance, I'll go in and have a look, no problem, right?

"Hehe, it doesn't matter!" The three of them just smiled, as if they didn't care that Chen Fei would snatch the baby!

"Then I'll start!" Chen Fei knew that the three of them definitely had hole cards and were not afraid of him.

He strode over to the iron gate, and with a wave of his palm, the fire of immortality struck the ice crystals!

"Wow~Click~" As soon as the fire of eternal life touched the ice crystal, the ice crystal actually dripped downward, and there was a cracking sound!

"It's done, it's done, the fire of eternal life restrains this ice crystal, hahaha!" When the three of them saw this, they all laughed excitedly!

Chen Fei continued to increase his firepower, and then broke through that layer of ice crystals under the gaze of the three of them!

"Buzz~Buzz~" As soon as the ice crystals were gone, the iron gate that had been frozen for an unknown number of years actually trembled and buzzed!

"You retreat to the end, I'll break the door!" At this time, the old blacksmith motioned for Chen Fei to retreat to the end, and Yang Zhen and the Medicine King also took a step forward!

Chen Fei shrugged his shoulders and stood behind, and after the old blacksmith glanced at him with slanted eyes, he sneered and said, "Don't move around after Xiaoyou goes in!" This is a warning!

"Yes, Xiaoyou can follow us, there may be a formation inside, it won't be good if Xiaoyou gets injured!" Yang Zhen also nodded with a smile, but Chen Fei was not a fool, Yang Zhen and the old blacksmith were warning him.

The Medicine King licked his lips with a wicked smile, as if Chen Fei was about to sprinkle poison if he moved slightly.

The three of them nodded, and when the old blacksmith exhaled, he slapped his palm on the iron door, and then the iron door shattered!

"Whew~" As soon as the iron door shattered, a huge cold air erupted from the door.

"It's not good, retreat!" The cold qi was the predecessor of the ice crystal, so the three of them shouted and wanted to retreat!

However, when the three of them retreated, the fire of immortality suddenly appeared on his body, and then he rushed forward like a retreat!

"How dare you ......"

"Stop!"

"You ......" When the three of them quickly retreated, they also drank again and again, because there was a treasure in it, they wanted to be advanced, but they couldn't withstand the cold mist, so they could only watch Chen Fei rush in!
