"Pu La~Pu La~" A group of indigenous people in the cave were alarmed by Ye Kaihuai and others who entered the cave. They flashed their wings and flew over the heads of Ye Kaihuai and others. Ke Lin, who was so scared that she hid behind Ye Kaihuai and hugged Ye Kaihuai and refused to let go.

"I said Collin, you'd better go back to the camp and wait for us..." Ye Kaihuai was interrupted by Collin before he finished speaking. He heard Collin say firmly: "No, when leaving Anping, Yuege and the others asked me to take care of you. I can't put you in danger."

"It's very touching, but can you let go of me first? I'm almost broken by you." Ye Kaihuai said with some difficulty in breathing.

After taking a few breaths, Ye Kaihuai said to Ke Lin behind him with annoyance: "You can follow me, but you are not allowed to tie my neck whenever you encounter any situation. I don't want to die at my own hands, and it's such a cowardly way to die."

"Oh." Collin agreed embarrassedly.

The cave was very quiet. Apart from the footsteps of Ye Kaihuai and others, Ye Kaihuai and others were not in the mood to talk and laugh. After all, this cave is not as good as outside the cave. What is in the cave is unknown to Ye Kaihuai and others. If it can be avoided, try to avoid it.

With this thought, Ye Kaihuai and others came to the source of the underground river and were immediately shocked by what they saw. Others did not know whether Ye Kaihuai knew or not, but Ye Kaihuai, who had memories of his previous life, knew that at the end of the underground river, there was a dam, and it was a artificial dam, which was really hard to believe.

"Ye Kaihuai, do you know this kind of thing?" Hughes, who noticed Ye Kaihuai's expression, asked in a low voice. Hughes's question attracted the attention of everyone who was still amazed, and they all looked at Ye Kaihuai.

Ye Kaihuai nodded and said to everyone: "This thing has been seen in the book, but this is the first time I have seen it."

"Then what's this thing called? What's the use?" Collin, who had been hiding behind Ye Kaihuai, couldn't help but ask curiously.

"This thing is called a river-blocking dam. Its specific function is to adjust the flow of a river. But what makes me strange is that generally speaking, if you want to build such a dam, you must temporarily divert the river and then change it back after the dam is built, or build it not far from the river, and then intercept it and divert it. But I remember that there is no record of diverting the underground river in Fengyang Town, and there has been no water since the underground river dried up a hundred years ago. So what is the purpose of the people who built this dam? I don't understand, don't understand." Ye Kaihuai couldn't help but shake his head and said.

"What do you do if you do so much? Since you already know the reason for the drying of the underground river, as long as you destroy the dam, the problem of water shortage in Fengyang Town will be solved." Ke Lin, who knew that the reason for the drying of the underground river was not caused by ghosts, was in a good state at this time, and he had to use magic to attack the dam.

When Ye Kaihuai saw this, he quickly reached out to stop him, "Don't do anything, if you destroy this dam at this time, we will all lose our lives, and I always feel that there is a strange feeling inside..."

"eccentric?"

"Well, think about it, if it were just a simple dam, how could the people sent by the lord of Fengyang City a hundred years ago not find a way to destroy the dam and leave it to us for now to solve it."

"As you say this, it's true, what should we do now?"

"Don't be anxious first, I'll take a look first." Ye Kaihuai stepped under the dam, reached out to touch it, and felt a little rough. Ye Kaihuai lowered his head and thought for a while, and turned around to shout to everyone who was on guard: "Arthur, come on."

Hearing Ye Kaihuai's words, Arthur came over with his weapon and a bone made of pig iron.

"Young Master, what's the matter?"

"Use your weapon to smash it here, don't use all your strength." Ye Kaihuai said, pointing to a place in the dam.

"Okay, please step back first, Master."

Ye Kaihuai took a few steps back as he spoke. Arthur swung his arms round, raised his bone rod to point at the place Ye Kaihuai pointed just now and smashed it down. A "clang" sound of metallic attacks came out. Arthur, who was shocked to the point where his hands were numb, stared at the place in front of him that was only sunken by himself. After his hand recovered a little, Arthur raised his bone rod again without believing in the evil.

"No need to smash it." Ye Kaihuai stopped Arthur's actions and stepped forward to observe carefully. That's right, the base of the cement-poured dam cannot be destroyed so easily.

Seeing Ye Kaihuai nodding, Hughes and others who had already surrounded him were quietly waiting for Ye Kaihuai to speak.

"This dam should have a control room, so everyone can look for it separately."

With a command, everyone immediately scattered and looked for the control room of the dam that Ye Kaihuai said.

Taking advantage of this gap, Collin came over and handed Ye Kaihuai a water bag to what he was thinking, "Drink some water, Ye Kaihuai."

Ye Kaihuai took the water bag and smiled at Colin: "Thank you, Colin."

"You're welcome." Ke Lin sat next to Ye Kaihuai and asked in a low voice: "Ye Kaihuai, can you tell me how you knew that the big guy in front of you was called Da Dam? Don't tell me what I saw in a book that I can't find now."

"ah?"

"Don't pretend to be stupid. When we first saw this dam, everyone was shocked and curious. Only you, in addition to shock and curiosity, there was a trace of nostalgia in your eyes..."

"Oh, Kelin, you observed it very carefully, hahaha..." Ye Kaihuai smiled at the back of his head.

"Don't interrupt, talk quickly."

"This is nothing, it's really like what Collin you said just now. I did see it in a book, and I can't see that book anymore. Collin, if you change your job as a prophet, you will definitely have a richer future than you as a magician."

"Forget it, I like to be a magician, and I lack interest in prophets." Collin refused directly.

In which book is recorded in this dam, this question is not an important question to Ke Lin and the others, and it doesn't matter whether they know it or not. Ke Lin was just curious about why Ye Kaihuai showed a different look from them when he saw the dam, but since Ye Kaihuai didn't want to answer, she wouldn't force Ye Kaihuai to answer her question.

Ye Kaihuai smiled slightly at Collin's understanding and said nothing. Looking at the dam in front of him, he continued to show his deity, just waiting for Hughes and Arthur to lead people to find the entrance of the cave.

"Not found?" Ye Kaihuai stood up and asked Hughes who came to report.

"Yeah." Hughes nodded, "We searched all around, but we didn't find the secret door and secret passage you mentioned. Arthur is now taking people for the second search..."

"Let's go find it together." After listening to Hughes' report, Ye Kaihuai stood up and joined the team looking for the dam control room. He still didn't believe it. How could a dam be built without a control room? If the dam is not built, how can the dam be controlled? "There must be a secret passage in the secret door, but it is hidden very hidden and has not been found yet." Ye Kaihuai said to himself in his heart.
