Cheng Yue was a little depressed.

As an excellent special forces, in this large-scale anti-terrorist operation, he could only watch the mountains of materials, weapons and ammunition in front of him from the periphery. The reason is that he is too young, only twenty years old, and he is worried that he will not be able to reach a tacit understanding with others when he participates in the operation for the first time. Although his strength was recognized and he was selected into the top operational group of the military region, he could only carry out support tasks and was not allowed to participate in direct operations.

It's late at night, and the hundreds of other elite special forces involved in the operation have already arrived, but they are all sleeping in tents in the distance, and the attack will be launched in the early morning.

Cheng Yue picked up a new thermal imager boredly, looked at it a few times, found nothing, picked up a manual charger, charged it, and passed the time for a while.

At this time, in this valley, which has always been dry, a large purple mist suddenly drifted from outside the valley, and this color of fog is really rare. It's a bit solid, and although the wind is blowing, it doesn't affect it at all. The fog drifted slowly but steadily towards Cheng Yue.

Cheng Yue glanced at it a few times vigilantly, the strange color of this fog gave him an ominous premonition, but he couldn't call others up because of a fog. Out of an abundance of caution, he picked up a gas mask and buckled it to his face.

This purple mist slowly enveloped the mountain of ammunition in front of Cheng Yue's eyes, swallowed Cheng Yue into it, and then slowly dissipated, just a few minutes, there was nothing left where Cheng Yue was just now.

Cheng Yue and a large number of supplies, guns and ammunition disappeared like this.

This matter has become a state secret and has never been able to crack it.

But none of this is Cheng Yue's business, because he is already stunned.

When the fog cleared, he found himself on a flat ground on a hillside, with a large pile of weapons and equipment in front of him, and it was daytime.

He measured the sun's position, and it looked like eight or nine o'clock in the morning.

This flat land is not small, and it is no problem for hundreds of people to stand up, but because there is no large open space on the hillside, it is very narrow and long, but it is also very smooth, there is not a single weed, and it has been piled up with all kinds of supplies and weapons and ammunition at this time. There is also a half-circle of stone walls around it, which is about half a person high, and it is very strong.

The shrubs on the hillside are quite dense and not very tall, and it seems that it is winter, and the color of the grass and trees is relatively withered. Looking down, you can see that there is a mountain road that is not very wide seventy or eighty meters away, next to a mountain stream, sandwiched by a high mountain on the opposite side.

The mountain is steep, and there is not a single sign around. Cheng Yueqi heard a lot of strange things, and he was not afraid, but more curious. He picked up a Beidou positioning terminal and saw that the machine was normal, but there was no signal. All the communication equipment was checked one by one, but there was still no response.

Could it be magnetic interference?

Cheng Yue took out the dagger, and there was a compass on the head of the handle, and the strange thing was that the compass was normal. If there is magnetic interference, the compass will spin around.

So, why isn't there any signal?

It's simply impossible, where is this?

Interesting, so interesting.

Because of guarding this large pile of equipment, Cheng Yue didn't dare to be careless, and he couldn't leave here, he took out a high-powered telescope and carefully observed both ends of the mountain road.

One end of the road leads straight out of the valley, but there are no people. It's interesting on the other end.

At the other end is a pass, about 60 meters long, very heavy, with an arrow tower on it, across the stream. Traces of smoke and fire were everywhere on the city walls and arrow towers. Several places were smashed to pieces, and some soldiers in ancient armor stood on the city walls, nervously looking at the path ahead. There is a big pine tree in front of the pass, dozens of meters high, I am afraid it is hundreds of years old, but the tree is full of arrows. The gate was closed, and the road before the gate was narrow and long, allowing only one or two people to pass. There is also a hole in the top, which can not only let in light, but also allow such a long closing door to form a small urn city.

What a dangerous pass.

Which crew is filming here, and the place is well found.

If you look closely, there is a long stone embedded in the door, and three words are written on it - Dusong Pass.

Looking at this big pine tree again, Cheng Yue smiled a little, so that's the case.

Wait, Dusong Pass?!

As a soldier, of course, he has studied the Xiongguan of the world. Among them, there is Dusong Pass, he remembers that Dusong Pass is a dangerous pass in the north of Hangzhou, in ancient times it was the gateway to Hangzhou, it was built by the Southern Song Dynasty to resist the Jin soldiers going south, and it was connected with Nanjing in the north, and Hangzhou had no danger to defend in the south, so it could only surrender. But after the Ming Dynasty, it fell, and now it only leaves a little bit of ruins, and it can't be rebuilt, how can I see it intact today?!

The crew is filming like this, and the investment is too big, right? It's a huge boulder. There were costumed soldiers in the city, but there weren't anyone on the film crew. Look at the giant pine that must have been protected, but it was full of arrows. No local government can say yes.

A very strange thought suddenly rose in Cheng Yue's heart

What time is it?!

Did you cross over by yourself?!

Cheng Yue's heart tightened, and he lifted the telescope on the city wall and carefully observed the city wall.

The soldiers at the head of the city were dressed in coarse cloth! The weapon is real!

Of course, this kind of cloth is very clear, and there is no place to produce it for a long time, and even if it exists, it only appears as a local handicraft. No one will wear it as a garment!

As for weapons, how can the filming be sharpened? And the expressions of those soldiers are very solemn, where can I find so many actor-level extras.

As for the flags on the city, because there is no wind in the valley now, the flags have not been unfurled, and there are no words to be seen. Cheng Yue had to take a serious look at the texture and workmanship, it was by no means a modern product, it was exactly the same as what he saw in the museum!

Cheng Yue couldn't help but be at a loss, is it really fake?

Just crossed over like that?

Don't have to die once?

Cheng Yue looked at the dangerous pass in front of him suspiciously, and at this time, a gust of wind blew, and the highest flag on the city wall stretched out, revealing a big character - Song!

Sure enough, it's the Song Dynasty!

Cheng Yue is now sure that he has crossed into the Southern Song Dynasty, he remembers that the Mongol attack on Dusong Pass was in the winter of 1275 A.D. in the first year of Deyou, and it was broken on the 23rd day of November in the lunar calendar. Although Dusong Pass is dangerous in the world, but the guard general Zhang Wei is not a general who fights to the death, and he fled after the city is broken, but Dali Cheng transferred to the capital to control Feng Ji and his younger brother Feng Qi did not retreat, and all died here. I don't know what day it will be now, it won't be such a coincidence, it's today.

Could it be that God brought me over to save the Southern Song Dynasty?

At this moment, he heard a little voice, subconsciously bent down to hide, and then looked to the other side with a telescope, and an army appeared in front of him.

In front were several wooden shelves, seemingly freshly made, each pushed by five or six people.

Cheng Yue knew at a glance that this was a trebuchet, because it was designed by the Hui people of the Yuan Dynasty, Ah Lao Wading and Yi Sima, and it was also called the Hui Cannon, which was later used in the attack on Xiangfan, and played a huge role, and the Mongols also called it the Xiangfan Cannon. However, the original is too big, and it is relatively narrow here, so it seems that the Yuan army can't attack at once, so I went back and made a few small return cannons to attack the city again. This time, he no longer had any doubts about his time back to the Southern Song Dynasty.

But what is surprising is that the soldiers pushing the trebuchet are wearing the same armor as the Song army on Dusong Pass. But the banner was from the Yuan Dynasty. A large number of soldiers who followed were also Song people, and each of them, in addition to their shields, also carried a bag of sand on their shoulders, which was obviously used to siege the city.

Cheng Yue couldn't help but feel very sad. He knew that these were the Southern Song army that surrendered to the Yuan Dynasty. What the Mongols are best at is to use the servant army as cannon fodder in front, otherwise with the hundreds of thousands of Mongol troops, how could they build such a large empire?

As the team got closer, the Mongol cavalry could be seen in the distance.

Cheng Yue couldn't help but be interested.

The Mongolian cavalry was the strongest armed force in the era of cold weapons, and as a soldier, Cheng Yue never expected that he would see a living Mongolian iron cavalry.

They were dressed in Mongolian beanie hats or simple helmets, and wore very light leather armor with iron plates on the outside, like fish scales. Riding on a stunted Mongolian horse, with a bow and arrow in his hand, each man had one or two spare or different bows and arrows to carry by his side, and there were plenty of arrows, and there were three quiver bags, all full. On the other side, some people are scimitars, some people are maces, and to Cheng Yue's surprise, some people still have crossbows and even firecrackers on them! Everyone is a fierce face, and they are indeed the best soldiers in the world.

Cheng Yue watched it interestingly, he really didn't know that the Mongols also used firearms.

Behind them were heavy cavalry, all armoured, with a spear in their hands, and the others were no different from the light cavalry. Because it was a battle, there were no spare horses.

Cheng Yue put down the binoculars, thought about it for a while, bent down and took out all three heavy machine guns and five light machine guns from the pile of guns, took a sniper rifle, and an automatic rifle were loaded, loaded the scope, opened the insurance, prepared all the spare ammunition, loaded the grenade launcher, opened a few boxes of grenades, and put them at his feet. Two more pistols were taken, loaded with bullets, and ten spare magazines, which were also kept handy.

Put on body armor, put on a steel helmet, and put another body armor around your waist like a skirt. Cheng Yue knew that the Mongols' arrows were far and accurate, and he had just come here, so he didn't want to die like this.

Cheng Yue was lying on the low wall, which was a satisfying ambush site. The view is very good, both from behind to hit the besieging Yuan army, and with grenades to blow up the road to block the retreat of the Yuan army. He finally understood what this narrow flat land was for, when it was used as an ambush in the pass, it seemed that it had been built a long time ago, but for some reason it was useless when it was time to use it, but it was used by him to cross.

Well, since I'm here, I'll do this and see if I can change history!
