Zuo Dengfeng knew what would happen next, so he quickly jumped back to the waterhole, without giving himself a chance and not giving Jade Whisk a chance, Zuo Dengfeng quickly turned back to the waterhole through the passage, and then floated back to the water, and after coming out of the water, he found that Yufu's clothes and gold armor were placed not far from the edge of the pool, and Thirteen was waiting nearby.

After a while, the jade whisk also surfaced, and Zuo Dengfeng stepped forward to pull the jade whisk up, and at this time the two had already walked out of their previous thoughts.

"What now?" After the jade whisk out of the water, sit cross-legged on the ground and dry the clothes.

"Go to the lake on the west side." Zuo Dengfeng pondered for a moment and spoke.

"Since the earthly branch is not here, is there any need to stay here?" Yufu was slightly puzzled when she heard this, and the clues showed that the earth branch was no longer here.

"The small island in the middle of the lake on the west side is full of trees, and I want to go over and see what is going on." Zuo Dengfeng said that his previous speculation was just his own speculation, whether it was really as he expected still needed ironclad evidence, in addition, he was also very curious about the small island in the middle of the lake on the west side, it was not yet the time when the trees were green, and the trees there were too vigorous, which was very strange.

Yufu nodded when she heard this, and didn't say anything more, she would be distracted when she spoke, and she would be angry when she was distracted.

After half a pillar of incense, the jade whisk clothes were dry, put on the talisman gold armor and Taoist robe, and came to the west lake with Zuo Dengfeng and Thirteen, this time she did not go into the water, the ancient city of Puguo has no earth branch, and the poison no longer exists, there is no need for the two of them to go into the water together, it is logical to give help when others need help, and it is too attentive to walk with others when they don't need help.

"Be careful, the lake here is already connected to the river, and there may be something underwater." Jade Whisk admonished Zuo Dengfeng before diving.

Zuo Dengfeng nodded when he heard this, and turned to inhale and dive, because it is connected to the river, the temperature of the lake here is low, but fortunately, the visibility is okay, and the previous grenade explosion was only in the water and did not reach the bottom of the lake.

The water in the lake is very deep, and the further you dive, the lower the temperature, the greater the water pressure, and it didn't take long for Zuo to rise to the top.

"What's going on?" Jade Whisk looked at Zuo Dengfeng who jumped out of the water.

"I don't know, it's too deep, you have to bring scuba gear." Zuo Dengfeng opened the wooden box and took out gas cylinders and other things.

"Okay, be careful, I'll take a look at the other rooms in the city." Hearing this, Yufu stepped forward and helped Zuo Dengfeng put on diving equipment, and after a while, Zuo Dengfeng dived again.

He still dives against one side of the stone wall, and it is safe to dive close to the stone wall, and he only needs to guard against the danger in front of him, otherwise he must take into account the front and back, although the earth branch is no longer there, he is still very cautious.

The further down he dived, the lower the visibility, and the more cautious he became, as he sensed something around him watching him, and after a few moments, this feeling was confirmed, and a mermaid flashed before his eyes.

The fish-man swam very fast, fleeting, but although it was a glimpse, Zuo Dengfeng still saw clearly that it was an adult male mermaid, compared to the mermaid caught by the anaconda, its body was much stronger, and it held a sharp weapon like a spear in its hand.

The flash of the mermaid made Zuo Dengfeng very nervous, and the Yin and Yang Life and Death Formula was not without flaws, and the keen intuition it brought was based on his own spiritual energy cultivation, that is to say, in the case of weakened underwater strength, the Yin Yang Life and Death Formula would still perceive the danger in the water according to his cultivation on land, which was not accurate, so Zuo Dengfeng could not judge whether the hidden mermaids around him could pose a threat to him based on his intuition, and how much of a threat they could pose.

At this moment, Zuo Dengfeng began to regret it, he shouldn't have thrown the grenade in his own cleverness before, the explosion of the grenade must have frightened them, and they must have been waiting under the water for now.

At the critical moment, Zuo Dengfeng slowed down the speed of his dive, and began to think about whether the risk he took was proportional to what he received, that is, whether he still had to take the risk of diving.

According to his style, since the earth branch is no longer here, he will not take risks, but he is not reconciled, he has the psychology of a thief who does not go empty, and he has spent such a big thing to come here, and he is very disappointed in the futility, and he wants to get some valuable clues.

After a short hesitation, Zuo Dengfeng decided to continue diving, he had previously rescued a juvenile mermaid by the river, and he was also grateful to them, presumably the mermaid clan would not rashly attack him, the previous mermaid was in the juvenile stage, it could not speak does not mean that the adult mermaid could not speak, if there was a talking mermaid, he would be able to know what happened here three thousand years ago.

On the way down, Zuo Dengfeng felt a strange sound, the sound was very low, the frequency was very fast, similar to the positioning sound waves emitted by bats and dolphins, this strange sound was only a few at first, and the further down the dive, the denser the sound waves became, which indicated that a large number of mermaids lived underwater, and they were observing him from a distance.

The diving device that Zuo Dengfeng wore was just a simple breathing device, and as the dive deepened and the water pressure increased, he felt all kinds of discomfort, the most obvious manifestation of which was the buzzing in his ears and the shortening of visibility.

Just when Zuo Dengfeng wanted to give up, he finally saw the bottom of the lake below, the bottom of the lake was not flat, but full of strange rocks and closed ravines, which showed that this was the bottom of the lake before, and the Yin and Yang Ancient City used the natural terrain here to reduce the workload by half at the beginning of its construction.

At the same time as seeing the bottom of the lake, Zuo Dengfeng also saw a large number of mermaids underwater, they were not hidden in the strange rocky ravines at the bottom of the water, but lined up neatly several feet above the bottom of the lake.

Zuo Dengfeng immediately rose sharply after seeing this scene, it would be good to say that these mermaids were unorganized and undisciplined, but the situation in front of them showed that they had a strict hierarchy and obedience, and the reason why they did not attack before was not because they were afraid, but because they were not ordered.

At the beginning of his sudden ascent, the group of mermaids with more than 100 people rushed towards him quickly, and they all held long and sharp water spears, the water spears were polished for stones, and the sharp and abnormally sharp spears were stabbed when they got close.

At this moment, Zuo Dengfeng finally understood what it was like to swim in the shallows and the tiger fall in Pingyang, the underwater is the territory of the mermaid, and his ability to reach here is limited, and in the face of the sudden attack, he can only force out the Xuanyin True Qi, freeze the lake and condense a piece of cold ice to block the water spear.

The merfolk who attacked him were both male and female, and the female mermaid was smaller, fair-skinned, and had handsome faces, but none of this prevented them from grabbing water spears to attack him like those majestic male merfolk.

One water spear is okay to say, two or three are not difficult to deal with, after all, the nine-fold reaction speed brought by the Yin and Yang Life and Death Technique is still there, even if it is damaged underwater, it is impossible to lose a little bit, but the number of mermaids is extremely large, it is done together, Zuo Dengfeng simply can't send out Xuanyin True Qi to condense the surrounding lake many times, so he can only rely on the tenacious Xuanyin gauntlet to directly block it, and at the same time quickly float up, it will definitely not be able to beat it underwater, and he can only escape.

Xuanyin gauntlets are not afraid of swords, but directly blocking these sharp water spears still makes Zuo Dengfeng cry bitter, these water spears are extremely sharp by mermaids, although the Xuanyin gauntlets can block the water spears, the palms are also very painful, the most important thing is that these water spears may be the weapons that mermaids usually hunt, they are extremely skillful, and the parts of the spears are very tricky, especially those female mermaids, they are not as good as those male mermaids in strength, but they are faster, and they swim quickly to attack, If you miss a blow, you will immediately change your position and come back with another spear.

Zuo Dengfeng defended and floated up, and soon he felt the water pressure weaken, and he only needed to hold on for a moment to get out of this dangerous lake, but soon he found that he probably couldn't surface, because a large number of merfolk quickly swam above him and speared to stop him from rising, while another group of merfolk circled below him, and frequently stabbed his feet with spears.

The upper and lower attacks made Zuo Dengfeng extremely passive, and he couldn't take care of the beginning and the tail, but he didn't dare to leave the stone wall, because the intention of these merfolk was to force him away from the stone wall, so that he could attack from the front and back, left and right, up and down at the same time, it can be seen that the IQ of these mermaids is still very high, and according to the tacit understanding of their writing and cooperation with each other, their ancestors are very likely to have participated in Jiang Ziya's Eastern Crusade, such a group of powerful goods, they are simply invincible underwater.

Even if he knew that leaving the stone wall would be more dangerous, Zuo Dengfeng had no choice, because if he didn't leave the stone wall, he couldn't dodge the water spear stabbed from above and below, between the lightning and flint, Zuo Dengfeng quickly weighed in his mind, the purpose of these mermaids was to force him away from the stone wall, so there was no obstacle in front of him, and he could take the opportunity to float a distance away from the stone wall at this time, but once he left the stone wall, he would get farther and farther away from the lake, and once the distance widened, he couldn't go back.

At a critical juncture, he didn't have time to think about it at all, knowing that it was a trap and had to get into it, in desperation, Zuo Dengfeng had to quickly step on the stone wall and rush out with strength, at this moment he scolded this group of mermaids in his heart for being ungrateful, how to say that he also saved their children, he couldn't speak the language of the mermaid, but the underage mermaid would definitely come back after being rescued and recount what had happened, I didn't expect these guys to be so ungrateful, taking advantage of the fire to rob and attack the benefactor.

After scolding the mermaid, Zuo Dengfeng began to scold himself again, his mentality is not right, after helping others, he thinks that others will thank him, this is a manifestation of no stomach, helping others is helping others, the other party knows that it is moral, and it is not bad to thank him verbally, and it is not a big deal to take revenge, after all, others did not ask for their own help, and in the future, others did not ask for their own help, and resolutely did not do it, no, even if others asked for their own help, they resolutely did not do it.

Zuo Dengfeng quickly rushed out with the help of the previous trampling on the stone wall, and the merfolk did not immediately rush over to attack when they saw him leave the stone wall, but swam between him and the stone wall one after another to block his retreat and prevent him from making a detour back to the shore.

The actions of this group of mermaids have a strong purpose and unified surname, which means that there is a leader commanding them, and they will not have the next move for the time being before the leader issues the next order, Zuo Dengfeng saw through this, he also understood that he could not return to the shore, and at the critical moment he made a bold move, using both hands and feet, and the aura was urging, and quickly swam to the small island in the middle of the lake, at this time he could already surface, but he did not do so, because once out of the water, he could not observe the underwater situation.

After a while, those mermaids rushed to launch the final attack, Zuo Dengfeng saw that the situation was not good, and desperately urged the aura to swim north, he grew up by the sea, the water surname is excellent, plus there is an aura urging, there was no mermaid to catch up in a short time, after a while, he came to the south side of the island, and when he was close, he found that the island in the lake was a floating island, and there was no foundation underwater.

After swimming again, Zuo Dengfeng made a new discovery, but this new discovery made him suddenly break out in a cold sweat, what kind of island is this?
