Gu Fengchun naturally didn't know that when Qiu Huiyan was carrying him, he had already made many small moves. He didn't even know that Qiu Huiyan was planning to put Chen Si and the Black Panther in one place. Qiu Huiyan had already figured out Chen Si's personality and thinking mode, deliberately formulated a series of plans, and calculated the time, only Chen Si and the others were in.

Qiu Huiyan thought like this: After luring Chen Si and his party to another path, then her series of plans began. He knew that Chen Si would definitely find that secret passage, and he would definitely come to the lake from that side, and then the hot water of the lake would suddenly pour over, and it would definitely kill and injure many people, even if he was lucky enough not to die for a while, it wouldn't take long to toss it, and the organs on both sides of the passage would be activated, the passage would be sealed, and the elixir in the inner layer of the stone wall would melt and seep out, converging into a huge pool of blood, and at that time, countless corpse blood pools would be bred from this pool of blood, These murderous creatures will tear the remaining ones to pieces. Then there will be no one to disturb her plans. This intention can be described as poisonous. According to her assumption, no matter how strong Chen Si is, he is not the opponent of countless corpses and blood, and by the time the lake recedes, they will already be dead, and maybe they won't even be able to find the corpse.

"Come with me." Seeing that Chen Si had agreed with her idea, Qiu Huiyan immediately made a graceful movement and jumped into the lake at once. The sound of "plopping" did not stir up much splash, which shows that her swimming skills must be extraordinary.

Gu Fengchun took out a small bottle of liquid oxygen from his backpack and handed it to Luo Xiaodan, this is the last bottle of oxygen on his body, the plateau is short of oxygen, this bottled oxygen team carries a lot, but Gu Fengchun's body has already been consumed, this bottle of oxygen still entered the stone tower, and when Da Yumu replenished his supplies, he found that he had no oxygen, so he divided a bottle of him. Da Yumu didn't suffer from altitude sickness, and he didn't wade much in the water, so he didn't need this thing. "Xiao Dan, are you ready, let's go down too." Gu Fengchun said.

Luo Xiaodan was silent, and after finishing the warm-up, he nodded, took the oxygen cylinder, and jumped into the water all of a sudden, although his posture was not as chic and agile as Qiu Huiyan, but it was much better than Gu Fengchun's loud "bang" and the posture of falling into the water that stirred up thousands of waves. At this moment, Gu Fengchun knew that Luo Xiaodan was not boasting when he said that his swimming skills were better than him. But Gu Fengchun always felt a little weird. I always feel that this Luo Xiaodan seems to have a very heavy heart.

"Come with me." After Qiu Huiyan spit out a mouthful of water, she immediately paddled forward. In order to save their physical strength, Gu Fengchun and Luo Xiaodan both used to lie on the buoyancy backpack, and then followed Qiu Huiyan to row. Gu Fengchun was a little shocked by Qiu Huiyan's physical fitness, even if it was compared to himself, I am afraid it was comparable.

"Dive down again when you get to the middle of the lake." Qiu Huiyan was swimming and talking, but it seemed effortless. She also had a waterproof lamp in her hand, and after swimming for a while, she swept around. Occasionally, they will dive underwater to reconnoiter the underwater situation.

"It's so cold." Luo Xiaodan sang with his teeth "gurgling". Luo Xiaodan regretted a little that he jumped into the water without finding out the water temperature, and he really thought he was Qiu Huiyan. As a result, the biting chill hit after falling into the water, and I immediately couldn't stand it.

"Hmm." Gu Fengchun also obviously felt that the water was close to zero, but he was not too uncomfortable with the water temperature, "Hold on, your body will warm up after swimming for a while, don't worry, I'm here, if you have cramps, you have to say." Gu Fengchun admonished beside him.

"Hmm." Luo Xiaodan had to tighten his teeth, and after listening to Gu Fengchun's words, his heart warmed. It seems that the troubles in my heart have been alleviated a lot.

After swimming for about thirty minutes, Qiu Huiyan suddenly stopped, shone the light in her mouth around, turned back to the two behind her and said, "This is almost the middle of the lake, let's dive, it's easier to find it underwater." ”

Gu Fengchun and Luo Xiaodan both said "um". Luo Xiaodan didn't notice that Gu Fengchun's eyes were full of consternation.

Gu Fengchun's consternation was justified. He swam here, of course, knowing that this was the middle of the lake, because he had night vision and could see everything around him clearly. But how did Qiu Huiyan know? Just the flashlight in her hand? Isn't that child's play? The flashlight could shine at most a distance of dozens of meters, but Gu Fengchun knew that his group's swimming speed was not slow, at least they had swam a distance of more than two thousand meters.

The only answer is that Qiu Huiyan, like him, is also a person whose eyes can see at night.

Thinking of this, Gu Fengchun felt a pang in his heart and thought; "Isn't Qiu Huiyan, like me, also the 'terminal product of billions of years of evolution?' Didn't the mysterious female voice say that there was only one? Gu Fengchun shook his head, thinking that there were more and more mysteries on Qiu Huiyan.

The bottom of the water is more than ten meters deep, and the pressure on people cannot be underestimated, Gu Fengchun and Qiu Huiyan naturally do not have much pressure, but compared to Luo Xiaodan, this is still a very high difficulty, she dived twice, and was forced to float up when she reached seven or eight meters. The eardrum was pressed by the water, and when it surfaced, there was a "buzzing" sound in the ear. She looked helpless, knowing that she had overestimated her level.

Gu Fengchun originally wanted Luo Xiaodan to stay on the water and wait for the two of them to turn on the switch before going down, but Qiu Huiyan resolutely did not allow this, she said: "If you leave her on it, it won't be long before she will be scalded to death by the boiling water." Only by staying below can it be safe, besides, without Luo Xiaodan, we can't open the mechanism below, believe me. With that, he dived.

Gu Fengchun had no choice but to pull Luo Xiaodan down to the bottom of the water with a ruthless heart, Luo Xiaodan was firmly grasped by Gu Fengchun with one hand, and the other hand held the liquid oxygen bottle tightly, inhaling oxygen in a big gulp. When the two approached Qiu Huiyan, Qiu Huiyan had already found the underwater mechanism familiarly.

The so-called underwater mechanism is actually a towering metal pillar, which has been soaked under the water for I don't know how many years, gray, and I don't know what kind of metal it is made of. There were many fine patterns carved on the metal pillar, but Gu Fengchun didn't understand what was carved there. In addition, there is a concave circle on the top of the metal pillar, and inside this circle, there is a round pit, which is just the size to accommodate the phoenix gall.

Qiu Huiyan gestured to Gu Fengchun and asked him to hand over the Shark King Bead (Phoenix Gall), and then she also felt a metal ring from her body. Seeing the metal ring, Gu Fengchun couldn't help but be stunned, it turned out that Qiu Huiyan also had such a metal ring on her body!
