Murong Yi and Feng Ziying looked curious, and Feng Ziying asked, "Commander Jiang has seen it?" ”

Jiang Yuxuan nodded and said: "I have seen in ancient books, this is a material made by humans, it is not natural, and this kind of material made is very strong, and our current equipment cannot be broken at all, which is why the reservoir has been here for thousands of years." ”

"Can't be destroyed?" Murong Yi said in surprise.

"It can be understood that way." Jiang Yuxuan said.

"Impossible," Feng Ziying said suspiciously: "We are much more developed now than before, and there are more towns, before the towns were villages, and there was nothing in the villages before, so what can be used to make such tough things." ”

"I've only seen it in ancient books, and it's a broken book, not complete." Jiang Yuxuan said as he looked at the reservoir, "Dig up the soil on the periphery of this embankment for a meter." ”

Murong Yi said in surprise: "This reservoir is so big, if you dig a meter under the embankment, I'm afraid you will have to dig it until tomorrow." ”

"Dig it."

Seeing that Jiang Yuxuan insisted, Murong Yi had no choice but to give orders to the army and start digging one meter under the embankment.

More than a thousand people, except for the garrison, the rest of the soldiers all picked up their tools and began to dig around the reservoir.

Watching the excavated soil roll down directly from the high slope, Jiang Yuxuan said, "Pile up this soil for me." ”

"Officer," Liu Zhen said, "digging is already slow, and it will be even slower to pile up." ”

"It's okay, hurry up and pass the order." After Jiang Yuxuan finished speaking, he inspected the embankment with Murong Yi and Feng Ziying.

In the morning, Jiang Yuxuan slept in the simple tent, and when it was dim, he heard someone shouting, opened his eyes, and walked out of the tent.

Seeing Murong Yi and Feng Ziying standing in front of the tent, Jiang Yuxuan said, "You guys got up really early. ”

"I couldn't sleep this night." Murong Yi said: "Director Jiang, just now Liu Zhen came to report, saying that all the soil on the embankment was dug one meter, and no abnormalities were found. ”

"Oh," Jiang Yuxuan's expression was solemn, "take me to see it." After speaking, he followed Murong Yi and the others to carefully survey along the dug embankment.

After the earth was excavated, the smooth and flat embankment was erected on the high slope, like a thick steel wall, tightly enclosing the water inside.

On the wall, there is no trace except for the residual soil, as if it were one natural.

"How was this built?" Feng Ziying looked at it in surprise.

Jiang Yuxuan walked and watched under the embankment, suddenly stopped, bent down, and wiped the soil at the bottom of the embankment with his hands, revealing a clearly visible trace.

The marks were as smooth as a sharp knife, barely visible and difficult to spot unless the earth on the embankment was wiped clean.

"There's a rift." Feng Ziying said with a staring eye at the trace.

"It's not a rift," Jiang Yuxuan stood up and said, "Follow this place, keep digging." ”

Hearing Jiang Yuxuan's order, the surrounding soldiers began to continue digging.

The earth slowly piled up on both sides, revealing more and more embankments.

"How deep is this thing?" Murong Yi looked at the embankment that was getting deeper and deeper, and a huge wall had formed, and asked in amazement.

"This embankment is at least a few tens of meters deep, maybe even deeper." Jiang Yuxuan said.

"Wouldn't it all the way down the slope?" Feng Ziying said in surprise.

"A thousand years ago, there may not have been such a high slope at all, only this bare embankment, which surrounded the water." Jiang Yuxuan said thoughtfully.

When the embankment was dug to a depth of more than ten meters and six or seven meters wide, a soldier exclaimed: "Look, there is something here." ”

Jiang Yuxuan, Murong Yi and the others walked forward quickly, only to see that between the embankment and the dirt, there was a pile of rusty iron-like things.

"Dig it all up." Jiang Yuxuan said.

"Yes." Seeing something coming out, several soldiers were full of motivation and quickly cleaned up the nearby dirt, revealing a rusty thing from top to bottom.

"Don't stand at the bottom, go all up." After Jiang Yuxuan finished speaking, he said to a few soldiers: "Smash this iron crack for me." ”

was already curious, but now listening to Jiang Yuxuan say this, everyone exerted their strength and kept beating on the rusty iron cracks.

The crack in the iron, embedded in the dirt, had almost been broken by rust, and under the attack of dozens of soldiers, it quickly broke open, and after the rust was cleaned away, a groove half a meter deep was revealed in the embankment wall.

In the grooves, there are many cavities ten centimeters in size, and there are some rope-like things in the holes that are intertwined.

"What the hell are these things?" Murong Yi asked suspiciously.

"I don't know," Jiang Yuxuan replied.

"Can this reservoir still be opened?" Feng Ziying said.

Jiang Yuxuan looked at the excavated embankment wall, touched the gap in the wall with his hand, and said, "Everyone continue to dig over there." ”

Hundreds of soldiers began to dig to the left, digging another six or seven meters wide, and after clearing the soil, they found that the embankment wall was concave, the height was level with the gap in the wall just now, the width was slightly wider, and the bottom was flush.

Jiang Yuxuan said after reading it: "Look, this thing can definitely be moved over there, and the grooves on this side must be switches, but they are all broken." ”

"This project is big enough, who made it." Feng Ziying said in astonishment.

"Whoever it is, this thing has to be opened now." Murong Yi said.

"Battalion Commander Murong is right," Jiang Yuxuan said, "Now you can only use brute force to pry this thing open." ”

Murong Yi shouted, "Everyone disperse and smash this thing hard." ”

The whole army dispersed, and struck the wall of the embankment with weapons and tools, and after five or six minutes, the wall shook slightly, and water began to overflow through the cracks.

"It's moving." Some of the soldiers shouted excitedly.

"Don't knock anymore," Jiang Yuxuan shouted, "Let's see if we can move over there." ”

Under Jiang Yuxuan's command, everyone worked together to move the wall to the left.

After a few rounds, the water on the right side was getting bigger and bigger, and Feng Ziying said excitedly: "It seems that it has moved, the water has come out from that side, everyone work hard." ”

"Battalion commander," a soldier shouted as he pointed to the bottom of the high slope, "look, it looks like Yan Haitong's army." ”

Murong Yi looked at it, if it was Yan Haitong with several battalions of troops, he was rushing over here.

Tian Pei walked on the edge of Yan Haitong and said, "Zhengong, you see that there are many people on the reservoir. ”

Yan Haitong looked at it for a while and said, "It doesn't matter how many people he has, anyway, there are not as many as us, just go up and do them." ”

Seeing Yan Haitong coming up with the army, Jiang Yuxuan said: "Battalion Commander Murong, I have left a coalition of troops here to open this reservoir, and the remaining troops will all be handed over to you and Battalion Commander Feng to block Yan Haitong." ”
