"Woo woo~~~~" A dull horn sounded on the Hengchuan River, and those who are familiar with it may be able to hear that the rhythm of this horn is somewhat similar to the horn of the Shu army to meet the enemy, but it is different.

The horn sounded three times, and at this time, no one could be seen on the Neijiang River, and even the soldiers of the Chengzhou Army stationed at both ends of the river retreated.

As soon as the horn sounded, Zhou Gongyi looked at Yang Yi and asked softly, "Your Highness...."

Yang Yi pondered for a moment and nodded: "Ring the clock." ”

In ancient times, there was no radio or other communication system, and the "clock" was used as a tool to keep time.

Zhou Gongyi got the order to let the flag bearer on the side play a flag to the opposite mountain.

Soon, a loud bell rang from the opposite side.

"Knock ......"

Then there was another sound.

The bell struck ten times, and no one was long and quiet, like the morning bells in a temple.

However, it was difficult for Yang Yi and the others to calm down in their hearts, and before the bell rang, their faces became solemn until the last bell rang.

"Boom...."

Zhou Gongyi, Wen Jihuai, Liu Xiaoduan, Cao He and other students beside Yang Yi were all trembling.

"It's started...."Zhou Gongyi's voice trembled a little.

Be quiet... Quiet terrible...

There seems to be only the sound of the wind and the sound of the rushing water in the Yokogawa River.

Just when everyone's hanging hearts can't move...

"Boom !!"

The first violent explosion came.

"Boom! Rumble! Rumble! ”

Immediately after, a series of explosions followed.

The earth trembled, the dust covered the valleys, the birds flew away, the rubble splashed everywhere, and even the water flowing outside the Yokogawa River was stirred up with ripples.

Subsequently, the air wave generated by the explosion spread from the mouth of the Neijiang valley.

Yang Yi's hair bun and wide clothes in his ears were gently lifted by the air waves, and Zhou Gongyi and Wen Jihuai on the side looked excited, supporting each other and unable to say a word.

The young students of the Guangming Academy standing in the back were shocked by the huge power of the explosion, and some even sat on the ground with a soft foot and a buttocks.

Looking at the river of the Hengchuan River, tens of thousands of people knelt on the ground, constantly kowtowing, and shouted: "The sky is above!" ”

The sound of children crying abounds.

No one has ever seen such a terrifying image of the heavens and the earth shattering, and they only sigh that the power of the heavens and the earth is nothing more than that.

Even Zhou Gongyi, the creator of the power of heaven and earth, his lips were trembling constantly at this time, and he couldn't say a word.

Yang Yi was the only one with a blank face, and he saw him standing in front of the crowd with his hands behind his back, his eyes staring straight at the cloud of dust that covered the sky and the sun where the explosion was, without any surprise.

"The landslide is in front and does not change color, it is our teacher!" Shao Geng, who was sitting on the ground, swallowed his saliva hard, looked at Yang Yi with admiration in his eyes and exclaimed.

All the students nodded in agreement.

In fact, Yang Yi was not as calm as they imagined, even if he expected it, after all, he had never really seen such a large-scale blasting scene in reality.

However, compared to the shock of the power of the explosives, Yang Yi was more worried in his heart, at this moment, the place where the blasting mountain was covered by the dust raised, and he couldn't see anything, and he couldn't judge whether the blasting was successful or not.

Half an hour later, the dust on the mountain finally slowly fell, and Zhou Gongyi immediately led people into Neijiang to check the situation.

Soon, Yang Yi got the news from Zhou Gongyi, but it was a mixed blessing.

The good news is that the blasting is about as expected, and the middle section of the mountain is completely blown open, and the diversion can be carried out as long as the rubble is emptied.

The worry is that although the middle section of the mountain has all cracked, the mountains on both sides have also been affected, forming an extremely unstable cliff that may collapse at any time.

At first, everyone thought that the cliffs on both sides would not have much impact, but when Yang Yi led everyone to investigate on the spot, they found that the cliffs on both sides were a huge trouble.

First, the cliffs on both sides were already crumbling due to the impact of the explosion, and rocks were constantly falling from the sky, making it impossible to clean up the river below.

Second, these two cliffs may collapse at any time, and if the two sides suddenly collapse after the Neijiang River is opened to water, it will lead to the interception of the Neijiang River, and the consequences will be unimaginable.

"A second blast is necessary!" Yang Yi immediately came to a conclusion.

Only by blasting again and causing the cliffs on both sides to collapse can the entire Neijiang project be completed, and the time is more urgent, and the dangerous cliffs do not collapse, and the work of cleaning up the river cannot be carried out smoothly.

Although the two cliffs were crumbling, and gravel was constantly falling, Zhou Gongyi also knew that now was not the time to worry about life and death, so without waiting for Yang Yi to order, he personally led the blasters to the cliff and began to drill holes and fill explosives.

Yang Yi saw that the time was urgent, and they had to rush to work overnight, so he immediately asked thousands of Chengzhou soldiers and more than 10,000 migrant workers to set up torches, and tens of thousands of torches illuminated the entire Neijiang River and valley as if it were day.

By midnight, the precipice's explosives were all filled, but just as the second blasting was about to be carried out, the precipices on both sides collapsed, and not only several demolitionists who did not have time to withdraw were killed, but even the lead of the precipice explosives on the left side was broken by falling rocks, resulting in the blasting not being carried out smoothly.

Yang Yi sent people to reconnect the main lead several times but failed, and after another blaster was accidentally hit by a falling rock and died, Yang Yi ordered to stop the emergency repair operation and wait for the cliff to stabilize before working.

However, until dawn, the cliff continued to fall, and I don't know what year or month it would take to wait. At the same time, worse news came: the water level of the Yokogawa River had risen again, and it would overflow the sluice gates and pour into the Neijiang River in a day at most.

"Your Highness! Let Gong Yi bring someone up, we can't wait! Zhou Gongyi said eagerly, now they are racing against time, if they don't blow up the cliff, there will be no time to clean up the river.

Yang Yi, who hadn't slept for two days and two nights, had red eyes, waved his hand and said coldly: "No, it's too dangerous." ”

Zhou Gongyi hurriedly said: "Your Highness! Now is not the time to worry about other things, I will go up and try, as long as the main lead is connected, we can complete the blasting, the time to clean up the river in one day is just right, if it is delayed it is really too late. ”

Yang Yi hesitated for a moment, and just as he was about to speak, there was a faint sound of falling rocks in front of him, and then a large piece of rubble fell.

"No one is allowed to go up without my order, and in this situation, whoever goes up will be sent to death!" Yang Yi shook his head resolutely.

Before Yang Yi's words fell, suddenly a figure rushed in from outside the tent, but it was Shao Geng from Guangming Academy.

"Old... Teacher! Oh no! Liu Xiaoduan and... Go up the mountain with Cao He to pick up the lead! ”
