As Ma Dai gave a calm and decisive "ignition" order, the guards in charge of signal transmission beside him immediately waved the small red flag in their hands, so the special combat team members who were ambushed in the far part of the canyon saw the order to start action through the telescope.

The special combat team members who were ambushed in the nameless canyon of Saarmin Mountain immediately lit the fire rope that they were responsible for detonating after receiving a unified order to do so. The team members hid at the top of the canyon, and the fire rope burned from top to bottom, until it burned out, it would ignite a large amount of gunpowder buried in the halfway of the mountain on both sides of the canyon, and then after the violent explosion, the mountain walls on both sides tore a large "wound", and the large and small rocks fell in an instant, completely blocking the valley.

General Wusunyou, who was passing with the army in the valley, looked up at the cliffs on both sides above his head from time to time, and somehow felt panicked in his heart. In order to prevent people from making dumplings in the valley, he deliberately divided the army of 40,000 into four teams, each team separated by several miles, and the fish passed through the valley.

Being able to be so cautious and cautious has proven that this right general still has a real commander, but this time he met the Shadow Operators who are the best at concealing their whereabouts and carrying out explosive ambushes, so his fate was destined to be very neatly drawn when he passed under the crotch of the two brothers Ma Dai and Ma Xiu in the high place.

In the textbook of the Crouching Tiger Martial Arts Hall, there is a chapter dedicated to how to lead an army through the narrow terrain of the canyon. The basic requirement was to divide the troops into pieces and follow them in small groups, with each other having to be far enough away from each other to pass through the canyon. As for the terrain reconnaissance before entering the valley, the soldiers who took the lead out of the valley to do a good job of defending their positions were even more detailed and comprehensive.

Although Ma Dai and Ma Xiu did not have the opportunity to go to the Crouching Tiger Martial Arts Hall for further study, they carefully studied the training materials left for them when the King of Pingxi left, and they also deliberately went to ask the eldest brother Ma Chao, Yan Liang and Wen Chou, who had just graduated from the Lecture Martial Arts Hall, for advice on what they did not understand. Therefore, when they arranged this canyon blast, they imagined the enemy general as an opponent of the same level as themselves.

In view of the possible deployment of the Wusun people to penetrate the canyon in stages, Ma Dai was not worried. As long as the gunpowder he brought with him this time was sufficient, he was sure that he would bury all 40,000 Wusun people in the canyon.

Ma Dai adopted the method of sectional blasting, selecting more than a dozen particularly dangerous and easy to detonate sites in the canyon, and then having people start digging deep trenches on the mountainside to bury gunpowder half a month ago. In order to prevent the Wusun people from seeing signs of human activity in the valley, the small units involved in the operation used the method of hanging from a high altitude, hoisting gunpowder from the top of the cliff to the halfway up the mountain, and then hoisting the excavated gravel to the top of the cliff and then transferring.

With Bian Xi, a master of camouflage and concealment, the hundreds of soldiers who planted gunpowder first entered the canyon with cans and cold water, and no one alarmed the beasts and snakes and scorpions in the canyon, and when they completed their tasks, the grass and trees in the canyon still maintained their original appearance.

Ma Dai's position in the middle was far away from the special combat forces in charge of operations at both ends of the canyon, about a dozen miles away, but this did not cause too many obstacles to the simultaneous operation of everyone. Because the Shadow Crew has mastered the flag language, and they carry this telescope with them. So when Ma Dai's low "ignition" order was given, the team members at both ends of the canyon received the order after a few breaths.

Although the flag language is not as advanced as radio, it is the best means of communication within visual range, and the speed of information propagating in space is equal to the speed of light, excluding the reaction and action time of the team members responsible for signal transmission in the middle. Because when the human eye makes fixed-point observations through a telescope, what he sees is actually the speed of light.

The fire ropes that come out of each detonation point are tied in groups of three, and although the smoke may be louder when burning, and even the Wusun people in the canyon can hear the "whoosh" sound, this is not very important. As long as the firerope can accurately penetrate the inside of the cliff where the gunpowder is buried, then the Wusun people can only watch in amazement at the instantaneous landslide and ground cracking.

Ma Dai had done a special test before the operation, and a fire rope was lit from the top of the canyon to the end of the burn out, which would not take more than a cup of tea (about 10 minutes). In the time of a cup of tea, even if the Wusun people saw a glowing fiery snake meandering down from the top of the canyon, their first reaction was to quickly approach each other, pick up the weapons in their hands to protect them, or shoot with bows and arrows.

Before seeing a large-scale gunpowder explosion, no one would choose to climb halfway up the mountain to fight a duel with the unknown "fire snake" at the first time, not to mention that the places where the gunpowder was buried were all cliffs perpendicular to the ground, and where it was so easy to climb up.

When the order to "ignite" was given, although they knew that it was just a cup of tea, the two brothers, Ma Dai and Ma Xiu, only felt that the time had passed so long. They watched as the high-ranking general of the Wusun people passed under his crotch and then walked off into the distance, and the expected but damn "boom" had not yet sounded.

"Oh my God, what kind of monster is that!" suddenly shouted the Wusun soldier who was in charge of observing the valley.

The Wusun man beside the soldier looked up at the cliff wall in the direction of his finger, and sure enough, he saw a dark and curved thing emitting black smoke, burning the flames and quickly jumping down to the bottom of the valley.

"It's a fire dragon!"

"Shrink the formation, everyone shoot it with bows and arrows!"

In the canyon of dozens of miles, such a chaotic situation was staged almost at the same time, and even the right general who saw the "fire dragon" with his own eyes, the first thing he could think of was to organize troops to kill the fire dragon who dared to jump to the bottom of the valley in front of him, how could he think that this was just a fire rope used to urge his life?

"Oh my God, it's in the cave!"

"Hurry up, hurry up, don't let that beast come out and hurt anyone!"

Seeing that the "fire dragon" or "fire snake" finally burrowed into the belly of the mountain halfway up the mountain, the Wusun people who were in chaos in the valley finally breathed a sigh of relief, and then prepared to evacuate the formation and hit the road again.

At this moment, a huge sound like the sky and the earth cracking exploded on the top of the Wusun people's heads, and without waiting for the people in the valley to make any movement, the exploded mountains and rocks were like tens of thousands of monsters going crazy, churning up and down in the valley with their teeth and claws, and finally under the effect of gravity, all of them fell into the canyon and smashed into the top of the heads of the Wusun people in the valley......

When the continuous rumbling sound continued to spread from near to far, Ma Dai's hanging heart finally fell at this time. He watched for a long time as the high-ranking commander of Wusun not far away was buried without a trace by the falling boulder in an instant after the violent explosion.

Ma Xiu was younger, not as calm as Ma Dai, he stuck out his tongue and said loudly to Bian Xi, who had a calm face: "Old Bian, you are too ruthless! This kind of play makes the Wusun people don't know what is going on until they die!"

Bian Xi also shouted at Ma Xiu loudly: "Boy, this is nothing! When Jia Wen and the military division bombed the Yizhou soldiers in Yixian County, that scene was spectacular!"

Why are these two people yelling and talking? It's just because the explosion was so loud that it's still ringing in their ears.
