Poplar and Iron Ox emerged from the water to catch their breath, and only when the blue fish blood in the pool gradually dissipated with the current, did the brothers dive back into the water to see if there was the big bronze box underwater.

The depth of the pool was about ten meters, and the two injured big fish were lurking at the bottom of the water, with their translucent shape, it would have been difficult to find them when they were lurking, but now there is a fish with wounds all over its body, and there are still wisps of blue blood oozing out.

Because of this, the poplar iron bull soon saw that the two big fish were close to each other and lay motionless at the bottom of the water, looking really pitiful.

Poplar Iron Bull tried to stay away from the two big fish, so as not to alarm them and they had to come up again and fight to the death with his two hateful invaders.

Although the pool was wide, the water was very clear, and the brothers looked around, and soon found that in the mud at the bottom of the water, something suddenly rose.

The two of them immediately swam over, and when they looked closely, they suddenly realized that it was indeed the huge bronze box.

The brothers looked at each other with surprise in their eyes.

It's a pity that when I swam closer, I found that the bronze box was lying on its side at the bottom of the pool, and the box was empty, and the yellow rosewood box with a sandwich that was originally set inside was no longer inside.

The brothers were disappointed, and Poplar first leaned into the box to take a look, only to see that there was indeed nothing in the box. However, on the four walls of the box, there are engraved words, although the words are covered with patina, but they can also be vaguely recognized.

Poplar read it carefully, and then made a gesture to the iron bull who was guarding the side, and the two brothers surfaced together.

"I didn't expect this to be the abyss at the bottom of the Immortal Cave! It seems that the man in black did not die after falling, but swam out along the dark river!" said Tie Niu.

"Yes!" Poplar nodded, "The bronze box fell from above, and the wooden box inside must have been separated from the copper box, even if there is any important treasure hidden in the mezzanine, I am afraid that it has been taken away by the man in black!"

Tie Niu looked at it and said, "Yes, it's like a few planks have been washed up by the water to the edge of the cave!"

Poplar said no more, but swam in the direction of the current towards where the plank floated.

Soon they arrived, and there was indeed a large plank of wood that had been washed against the rock wall by the current.

The other outlet of the dark river is naturally under these planks.

"Why are they all splintered planks, and is the impact of falling from above so great?" said Iron Bull.

"There should be!" replied Poplar, "Don't you see that the bronze box is also deformed?, not to mention that the man in black must have to open the mezzanine to take away the important treasures, so naturally he will dismantle the whole wooden box!"

Poplar said as he fiddled with the planks.

Not all of the planks were scattered, and some of them were joined together, but the shape of the box was no longer visible, and it was impossible to find anything else.

"I saw the words in that bronze box, what was written?" Iron Bull asked again.

"It's about the identity of the man in black!" Bai Yang replied, "He is indeed surnamed Dongfang, and his single name is an English character, and the word is far away." And he is indeed the thief who deceived the Biyou Goddess, and he said that the woman he was most sorry for in his life was the Biyou Goddess!

"Then did he mention the immortal medicine list and the immortal medicine?"

"I didn't mention it, but the wooden box fell from such a high place, and even if there was an immortal elixir hidden in it, I am afraid it would have been flooded. As for the immortal medicine list, even if it was not damaged by water, it must have been taken by the man in black. ”

"Then we're still a bamboo basket for water, right?" Tie Niu shook his head with a wry smile.

"It can't be said that the bamboo basket fetches water, at least we know that the man in black is still not dead, and we can watch out for him in the future!"

By the way, your dagger is still in the belly of that big fish, do you want me to cut open the belly of the fish and help you take it out?"

"I think it's better to forget it! Such a big fish, if you really want to cut open the belly of the fish to find a dagger, I'm afraid that it will waste a lot of time and energy! If the fishy smell attracts other monsters, it will be even more troublesome!"

"But what if you don't have a weapon?"

Besides, this translucent fish can only live in the dark, and I don't think we will ever encounter this strange fish again if we swim out of here!"

Poplar replied, while looking at the plank floating on the water, looking for a piece that was not too long and holding it in his hand, and breaking it with both hands, the plank was immediately broken into two thinner pieces, one of which had a very sharp head, and Poplar took it in his hand and raised it towards the iron bull, and said, "This can also be used as a weapon!"

Iron Bull smiled, took a deep breath, and dived into the water in front of the poplar.

The water was next to the rock wall at the bottom of the pool, and sure enough, there was a flat outlet, and the water was rushing in from the outlet, forming clear water lines.

The Iron Bull burrowed into the drain, and Poplar followed.

I felt that there was a suction pulling the two of them, and without any effort, they sneaked down the river for hundreds of kilometers.

The brothers just pressed their mouths to hold their breath and waited until the water slowed down, and then paddled with their hands and feet.

It took half an hour to paddle, but it was impossible to estimate how far ahead. The brothers had no choice but to grit their teeth and move on.

Until Poplar felt a little unable to hold back, the iron bull in front of him slowed down significantly.

Poplar had to swim to the front next to the Iron Bull's body, and looked at the Iron Bull, only to see that his face was blue, and he had obviously reached the limit of holding his breath.

Poplar had to stretch out a hand to grab the Iron Bull and continue to move forward, but the Iron Bull shook his head at him and said that he could still hold on.

Poplar had no choice but to lead the way in front, and had to slow down for fear that the iron bull would not be able to keep up.

After swimming forward again, Poplar heard the sound of "cooing" in his ears, and when he looked back, the iron ox was already dancing with his hands and feet and opening his mouth to pour water.

Poplar was taken aback, knowing that in another hour and a half, the Iron Ox would be drowned alive.

But at this moment, there was nothing to be done, and he was about to dive behind the iron bull, pushing the iron bull to continue forward, and suddenly a strong suction force pulled him forward and crashed into the crooked river. Immediately following the rotation of the body, it is as if falling into a large vortex.

Poplar couldn't help but want to call out "Iron Bull", but his mouth immediately poured into a mouthful of river water. Hurriedly closed his mouth again, and felt an upward buoyancy push him up, and suddenly the pressure on his body disappeared, and his whole head came out of the water.

Poplar took a deep breath, didn't care about looking at the situation around him, just opened his eyes and searched in all directions.

Fortunately, he soon saw the Iron Ox also emerge from the water, but he seemed to be unconscious, so he emerged from the water and sank back down.

Poplar hurriedly swam over, grabbed the iron bull's arm, and pushed him out of the water first, and then looked around.

All around was dark and I couldn't see the edge, and when I looked up, I saw the stars shining in the sky.

Poplar immediately understood that they had really come out of the dark river, and that they should be on the surface of a wide lake now.

In normal times, no matter how wide the lake aspen is, it will not be put in the eyes, but the iron ox has poured a lot of water into its belly, and if it is not rescued quickly, it is afraid that there will be death and no life.

Bai Yang's mind was spinning, and he quickly turned the iron bull around, he leaned against the back of the iron bull, hugged the iron bull's chest and abdomen forward with both hands, and hugged the iron bull with his arms.

A large amount of water immediately gushed out of Iron Bull's mouth, and immediately after that, Iron Bull was heard panting and coughing briefly.

Poplar breathed a sigh of relief and hugged again.

Tie Niu coughed involuntarily, followed by a chattacle cough.

But this is a good phenomenon, Bai Yang hugged it again, and heard Tie Niu coughing while asking vaguely: "Lao Bai, why are you hugging me so tightly?"

If he hadn't been floating on the water, he would have been paralyzed, but he said, "You just drank a lot of water, and I had to force your water out!"

The Iron Bull let out an "oh", floated on the surface of the water with the help of the poplar, looked around, and asked, "Where have we been, have you come out?"

After asking one sentence, he couldn't help coughing a few times.

Poplar patted him on the back, waited for his coughing to stop, and then said, "It's already out! It's just that it's in a big lake now, you take a breath, we both have to swim to the shore!"

Tie Niu agreed, and said to himself: "It was really uncomfortable when I just choked on the water, I wonder why there are still many people who choose to jump into the river and the sea!"

Bai Yang didn't expect him to think of this at this time, he couldn't help but smile, holding his arm with one hand, while looking into the distance, feeling that this lake should be in a big mountain, and the mountain in front of him on the left should be a little closer to them.
