When the moon is in the sky, the sky and the earth are gray.

In the desolate canyon, a large army trotted forward with torches, the pace was uniform, no one was noisy, the firelight illuminated the indifferent faces, and the eyes were full of fierceness, which was the iron-blooded killing momentum formed by countless life-and-death battles.

Qin Huaidao took the lead in the front, constantly observing the surrounding mountain-shaped landforms, while comparing it with the map in his memory, confirming it, followed by Luo Ying and Luo Wu.

After a full night, plus most of the day's rest, the soldiers recovered a lot of physical strength, and in the rear of the army were countless pack horses, carrying a lot of materials needed for battle.

The wilderness is uninhabited, so quiet that it is a little permeating, the surrounding mountains are bare, there is no grass, it is clear at a glance, and it is a bit desolate and dead under the moonlight.

Soon, the front became narrow, like a large mountain cracked in half from the middle, the mountains on both sides were steep and impossible to climb, the middle passage was about thirty meters wide, and the front was deep and long, and it looked gray and dreary, like an entrance to hell.

"Stop!" Qin Huaidao raised his arms and shouted.

The army stopped, looked ahead in surprise, wondering if there would be an ambush, and couldn't help but press the handle of the knife with his hand, waiting solemnly, and an inexplicable killing momentum suddenly broke out.

"Uncle, what's wrong?" Luo Ying and Luo Wu stepped forward quickly, looked ahead and shouted curiously.

"Remember what the merchant said? It is known locally as the 'Valley of the Wolves', and it is a necessary place for all parts of the Tocharian kingdom to travel eastward to the city of the Bolesan River, and the city of Duda is no exception. Qin Huaidao explained.

Luo Ying looked at Luo Wu with some surprise and asked.

Luo Wu didn't know either, it seemed that those merchants had said it, and it seemed that they hadn't said it, so he couldn't remember it clearly.

Qin Huaidao has a strong memory, and when a businessman mentioned it, Qin Huaidao wrote it down, and asked about the terrain characteristics, so he chose the battlefield here.

The terrain is not dangerous, on the contrary, it is very flat, about thirty meters wide, the war horse can pass smoothly, there is an ambush can also be seen at a glance, the peaks on both sides are about fifty meters high, can be used to ambush, but the slope is steep, can only shoot arrows at a high level, can not rush down to fight, if you send troops to block the front, it is an encounter.

In its heyday, the Special Operations Army was not afraid of any encounter.

Although after a day and a night of rest, but the physical strength has not recovered to the peak, it is difficult to say who will die in the head-on encounter, even if it wins, it will be a miserable victory, Qin Huaidao will not use the trump card that he has trained with great difficulty to fight a war of attrition, and decisively ordered: "Guard regiment, go up to investigate, be careful of wolves." ”

"Follow me!" Luo Wu quickly rushed forward with the guard regiment to investigate.

Torches rushed up, illuminating the gray valley a lot, and there were all kinds of footprints on the ground, and there were traces of wheels crushing, and the road had to be passed not only by armies, but also by caravans.

Not long after, Luo Wu hurriedly came over: "Uncle, there are no people inside, and there are no wolves, the brothers are still exploring the way, but they found that it is not a corpse, it seems that it has been eaten by something." ”

"The only way, people come and go, and naturally it has become a hunting ground for wild wolves, so it is called the wild wolf valley by the locals, and it is normal to have gnawed bones, it seems that the wild wolves have found us coming and have retreated, and the guard group continues to investigate." Qin Huaidao admonished.

After Luo Wu agreed and left in a hurry, Qin Huaidao stepped forward with a horse lance in his hand and shouted, "Luo Ying." ”

"Here!" Luo Ying hurriedly caught up.

"Wherever it is pointed, arrange for people to dig pits somewhere, bury the oil they brought, not too deep, cover it with floating soil, and the excavated soil is also sprinkled, not too obvious to arouse suspicion." Qin Huaidao admonished, striding forward.

Luo Ying agreed, and hurriedly led someone forward.

Some distance ahead, Qin Huaidao observed the surroundings for a moment, and drew a circle on the ground with a horse lance.

Oil can be burned, obviously Qin Huaidao is preparing for a fire attack, but the burial point can't be messed around, and it definitely can't be in the middle of the road, the area where the enemy troops are walking, the soil is newly dug, and the height is uneven, it is easy to arouse suspicion, and it can only be on both sides.

Qin Huaidao estimated the central axis of the canyon, and reserved a space of ten meters for the enemy to walk, that is, twenty meters, and 20,000 troops walked over, because after passing through the canyon, it was impossible to rush up, and it was most likely to line up twenty columns to pass, with one thousand people in each column, and the team would not be too long.

Because it was night, and the canyon was narrow, people would instinctively stay as close together as possible, and walk in the middle, one meter for each person, and exactly twenty meters for twenty people.

Ten meters to the left and right of the central axis, exactly twenty meters, enough for the enemy to go along.

Qin Huaidao chose to bury the oil in the area outside the range of twenty meters, as long as the camouflage is good, it is not easy to be discovered, and then arrange people to go up to the top of the mountain to ambush, you can't see the foot on the top of the mountain, but you can see the area of twenty meters of the central axis, just ten thousand arrows fired at once, and the other party was caught off guard.

Once the enemy is attacked, it will inevitably run in both directions, and the explosive bag will fall from the top of the mountain, not only blowing people, but also igniting oil, causing even more terrible damage.

This is a technical job, and it is a little difficult for Luo Ying and Luo Wu, so Qin Huaidao came over in person.

Half an hour later, a thousand jars of oil were buried, and when the oil was gone, it could be grabbed again, and if the people were gone, it was really gone.

"Luo Wu!"

"Here!"

Qin Huaidao pointed to the buried oil and said: "I'm not sure when the enemy will arrive, you must be prepared for a night battle, I will have people put torches in the location where the oil is buried, you take people to the top of the mountain, bring all the explosives bags, and pay attention to the position of the torches after arriving at the top of the mountain, each person is responsible for a position, and after the battle starts, cast according to the position, don't throw the wrong one." ”

At night, you can't see anything clearly when you look down from above, so you can only use torches as a mark, so that people can know the general direction in advance, so as to avoid the wrong injection of explosives and the failure to ignite the oil, which will be a big loss.

"Understood!" Luo Wu solemnly agreed and took the guard regiment to prepare.

"Luo Ying, put the torches well, be careful, don't ignite the oil and hurt yourself by mistake, and then arrange a division on the top of the mountain, the top of the mountain is too high, you can't see the situation below, take the torch as the number of three circles, then the crossbow, bow and arrow will hit me hard, don't aim, don't save, and then arrange a division to be responsible for choking the tail, can't let one go, the remaining two divisions retreat, find a place to hide." Qin Huaidao solemnly admonished.

"Obey!" Luo Ying saluted solemnly and called five division commanders to deploy it.

Soon, the army moved into action, retreated some distance with supplies, found a gentle slope to climb to the top of the mountain, and planted torches as a sign where the oil was buried.

Qin Huaidao waited patiently, the fast-moving torches were enough to know the location of the army, seeing that the army came to the top of the ambush circle, Qin Huaidao continued to wait, there was no communicator, and he could not communicate in time, it was all based on experience.

After waiting for a while, it was estimated that everyone remembered the location of the oil burial, so he took the remaining two divisions back a distance and found a corner to hide.

The deployment just now was all for the enemy to arrive at night, but it was also possible to arrive in the Wild Wolf Valley after dawn, lacking intelligence, so he could only make various preparations in advance.

"Command, rest in place, and make no noise." Qin Huaidao said a word of advice, and found a place to sit down and pretend to sleep, but his ears were pricked up, listening to the movements around him.

When an army of 20,000 comes, the movement will not be small, and there is no worry that it will not be heard.

Soon, there was silence all around, except for the sound of breathing.
