Gu Yuan decided to go around to the south side of the city tower to see the sluice, after he moved, Ah Wu looked down and saw a ring on the ground, judging by the size, it should be worn on his thumb.

Ah Wu's expression was a little weird, and after hesitating, he secretly picked up the ring, and his expression became more indescribable.

In Liu Wencheng's shout, Ah Wu nervously stuffed the heavy ring into his arms, trotted to follow, and walked a thousand feet away before reaching the south side of the city tower.

A few people first saw two huge turntables made of stainless steel, the handles were polished and shiny, Ah Wu threw Zhao An on his back on the ground and tried to push it, but the turntable did not move at all, and it was difficult to push it with the strength of his body.

Gu Yuan has now developed a good archiving habit and silently saved a file.

Looking into the distance, a vast and ethereal ocean comes into view, and the end cannot be seen with the naked eye.

"I can't imagine it. Gu Yuan was amazed.

"The water here is not at its highest level yet. Liu Wencheng was equally dumbfounded.

"How do you know?" Ah Wu, who couldn't shake the turntable with the true yuan, was quite helpless, and when he heard Liu Wencheng's exclamation, he clapped his hands, looked at Liu Wencheng's back and asked.

Liu Wencheng replied proudly: "Is there anything in the world that I don't know?"

Awudun was respectful, just by looking at it, Liu Wencheng knew the depth of the water level, how did he see it?

This person really pretended to be knowledgeable.

"You listen to his nonsense. Gu Yuan rolled his eyes and said, "There are carved lines painted on the wall." ”

"......" Ah Wu wanted to hit someone.

"What are those two turntables for?" Gu Yuan asked curiously.

Liu Wencheng squinted his eyes and did not reply.

Gu Yuan coughed dryly and rolled up his sleeves.

Liu Wencheng immediately replied: "One is the inlet gate, and the other should be the outlet gate." ”

Awu Gaga laughed for a moment and asked, "What are we going to do next? Get out of here as soon as possible?"

"Of course. Gu Yuan replied: "Pang Yuan didn't get the desired result, the witches will continue to attack Shepan Mountain, without the March fireworks crossbow, we can't hold it." ”

"What the hell does Chai Jin think, the rivers below the mountain are blocked, and the water has no strength to rush to the top of the mountain, so he still wants to wait until the water rises to the highest level before opening the flood gates?"

Gu Yuan pondered for a moment and said, "I think he wants to live and die with this mountain." ”

"Huh?" Liu Wencheng and Ah Wu looked at Gu Yuan in surprise at the same time.

"When the witch can't bear to attack the mountain with all his might, he will definitely open the floodgates, and before that, he wants to make the water store deeper, right?"

"Remarkable. Liu Wencheng and Ah Wu said in unison.

Ah Wu asked very incomprehensibly, "But what is he doing this for?"

"Some people are destined to be different from us. Gu Yuan walked to the turntable and held the handle in his hand, "He regards the people of the world as more important than his own life, and for the sake of tens of thousands of people, he resolutely gave up his life." ”

The green tendons on the back of his hand bulged violently, and bursts of thunder came from Gu Yuan's body, which was caused by the fact that the true yuan was too thick and circulated too quickly in the meridians.

The injuries he suffered in the previous battles were all healed under the powerful self-healing ability of the druid's heart, and with the improvement of his cultivation, the "Moving Mountain Technique" became more and more sophisticated, and the qi and blood in Gu Yuan's body became more and more vigorous, even if it was a broken limb and reborn, it would not make him feel too weak, let alone those small injuries that had not yet broken his muscles and bones.

There was a clattering sound of gears turning inside the city wall, at first, Gu Yuan could only move forward little by little, but when the turntable completely rotated, his pace became faster and faster, and the noisy sound of water came with it.

Liu Wencheng's face gradually changed, and he became more and more surprised, and finally shouted loudly: "You opened the wrong door!!"

Gu Yuan's time was like being struck by lightning, stunned on the spot, Liu Wencheng and A Wu hurriedly swept to his side, reversed the turntable back, all this happened in only half an hour, the stored river water lost at least half of the water, all rushed into the river floating in the river, rushing in the direction of Wanfu Pass.

In winter, the sluice gates only open a gap, so that the river rushing up from the bottom of the mountain has the strength to carry the large amount of water that flows into the reservoir. Now that the rivers are blocked by corpses, there are not many rivers going uphill, and Gu Yuan has opened the floodgates again, how can there be a reason why the stored river water does not flow back?

Fortunately, the remedy is timely, but it is difficult to submerge most of the wilderness.

Liu Wencheng slapped the turntable angrily and said, "You can open the wrong door here?"

Gu Yuan replied with a weak heart: "The two turntables look the same, it's normal to make mistakes...... It's normal......."

Liu Wencheng had a cold face, pointed to the word "in" in the center of the turntable and said: "Open your eyes and look carefully, clearly marked 'in' and 'out', can you still make a mistake?

Gu Yuan's cheeks flushed, he saw that Ah Wu had been pushing this turntable, so he didn't even look at it, he wanted to show off his strength in front of the two, but he didn't expect that it was the sluice gate that was turning.

Rubbing his face in embarrassment, Gu Yuan whispered, "Well, go back ......"

......

Time back to the first time a few people arrived at the sluice, Gu Yuan wiped a handful of sweat on his forehead, glanced at Liu Wencheng who was sighing with admiration, and glanced at Ah Wu who was struggling with the turntable.

Stepping towards another turntable, he clearly glanced at the word "out" in the center of the turntable, Gu Yuan snorted, the muscles of his arms swelled several times, and he pushed the turntable with all his might.

With a bang, the sound of the mighty water resounded through the sky, and a huge white torrent poured down from the mountain and flew away in the direction of the great wilderness. The mighty river uprooted the city, uprooted the trees, and soon disintegrated the mountain into gravel and dirt, and the silver-shaped flood turned into a mud-colored dragon, roaring and pounced farther away.

The miasma shrouded in the sky over the jungle seemed to be frantically stirred by an invisible hand, and the mud waves stirred up several feet high, and they were powerless to fall, but the miasma that permeated the air was obviously diluted by the mud flowers.

Gu Yuan opened the flood gate without saying any hello, and Liu Wencheng shouted in shock: "What are you doing?!"

"We can't hold the Snake Mountain, and I don't have much desire to sacrifice my life for the common people in the world, but it is still possible to drown some witches and reduce their troops. Gu Yuan spread his hands and said, "It can be regarded as a contribution to the people." ”

After that, Gu Yuan took a lot of effort to repeat the words of Chai Jinmu's previous thoughts, but this was all his own hardship, and he couldn't complain about others.

A fire also burned in the arena, black smoke billowed from inside the city, and the mud-colored dragon outside the city split into countless tributaries and raged in the jungle, and countless people would be killed in this way.
