The next day, over Chang'an City.

Yang Yifei stood quietly above the clouds, overlooking the ancient capital of the Thirteen Dynasties, and his eyes were mainly focused on the palace complex in the northern part of the central axis of Chang'an City.

That is the "Taiji Palace", one of the three major palaces in Chang'an Palace, and the other two palace groups are "Daming Palace" and "Xingqing Palace".

This Taiji Palace is now the palace of the Great Khan of Mongolia, but Yang Yifei knows that this place will soon belong to him, because he intends to establish the capital of the new dynasty here, which means that he will restore the Han and Tang dynasties of the Chinese nation.

Five dynasties and ten kingdoms ago, Chang'an was the most prosperous city in the world, covering an area of more than 60,000 square kilometers, six times the size of Xi'an in later generations.

However, since the peasant uprising at the end of the Tang Dynasty, the northern ethnic minorities continued to invade, and the Han people moved south on a large scale, and Chang'an gradually declined.

But in fact, this city is an excellent place to build the capital, itself is easy to defend and difficult to attack, inside the central plain this large granary, outside the tiger prison, Hangu Tianxia Xiongguan, as the capital is very suitable.

The establishment of a peaceful and prosperous era began with the laying of Chang'an.

Yang Yifei set his eyes further north, only to see that at this time, groups of people wearing Tartar costumes were gathering from all over the city to the north gate with the old and the young.

After all, he did not dare to ignore Yang Yifei's ultimatum, and the Mongolian people were ordered by him to temporarily move out of Chang'an and go north to Tongguan County to live temporarily, but the 16,000 soldiers and horses stationed in Chang'an did not move.

If they haven't done a game, but just see the notice distributed by the other party and leave in disgrace, then they don't need to think about the problem of chasing the world, just roll up and go back to the grassland!

Seeing the Mongolian people leaving, Yang Yifei also secretly breathed a sigh of relief, so he had no scruples, all the people left behind were sergeants, as a soldier, it was natural for him to die on the battlefield, and he would not be soft when he killed.

After determining the movement of the Tartars, Yang Yifei returned to Tianziyu and waited for the three-day period to come.

In the past three days, Sun was not only evacuating the people, but also sent a large number of spies to search for traces of the enemy army south of Chang'an.

However, the number of Yang Yifei's troops is too small, and the garrison is hidden, how can it be found in just three days?

Three days later, in the early hours of the morning, the teaching team had a full meal, then packed up a set of equipment, pulled out the camp and set off, and Yang Yifei distributed ammunition before departure.

The training team was divided into four parts, one of which was a heavy machine gun squad, armed with 4 heavy machine guns and 12,000 rounds of ammunition of 3,000 rounds each.

A mortar squad, armed with 4 mortars and a box of shells each, for a total of 144 rounds.

A sniper squad armed with 8 anti-materiel sniper rifles, 20 bursts each, a total of 160 rounds, and 80 ordinary solid rounds, a total of 640 rounds.

The remaining 3 squads are ordinary infantry squads, each carrying 300 rifle rounds, 80 pistol rounds, 3 offensive grenades, and 2 defensive grenades.

In addition to basic equipment, Daniel Zhang and Tian Peng also carried a bazooka, while Liu Yuxuan existed as an artillery commander.

The three of them were also ready to carry out aerial firepower strikes with Yang Yifei and Li Mochou at any time, and Qiu Chuji served as the commander-in-chief of the teaching team.

Taking advantage of the night, the group marched along the official road, and when the sky was dark, they moved to a position about 1,200 meters away from the southern city wall of Chang'an City.

This is a small forest, the trees are not high, the average height is about two zhang, Yang Yifei found a flat place, released the 10 high platforms, and stood side by side.

Each tower is equivalent to a watchtower, with a thatched shed on top to prevent rain during battle, and there are two square areas on the tower, on which there are firing supports, in addition to 8 snipers, 4 heavy machine guns can also be mounted.

After preparing for battle, Yang Yifei ordered to rest for half an hour, and then replenish some dry food and drinking water, at this time, everyone's carrying gear was taken back by Yang Yifei Storage space, and the dry food in their satchels was some bread, compressed biscuits, ham sausages and the like.

The morning sun gradually rose, and the vision became clear, Yang Yifei and Qiu Chuji stood on a high platform, each holding a telescope to observe the southern city wall of Chang'an.

I saw that the city wall was already full of Tartar soldiers at this time, and there were crossbow arrows with the thickness of thumbs extending out of the gaps in the female wall, which were the crossbows of the bed crossbows, but there was no return cannon.

Qiu Chuji put down the binoculars and said: "The return cannon is usually erected behind the city wall, and generally not on the city wall, if we want to destroy the opponent's artillery position, we have to know the specific coordinates." ”

Yang Yifei nodded and said, "Leave it to me." ”

After saying that, he flew up to the sky with his sword, and returned after a while, he called Liu Yuxuan, told him the coordinates of the erection location of the Tartar return cannon, and then ordered him to lead the artillery team to find a place without shelter on the head to set up a cannon position.

Liu Yuxuan took the order, and he also held a walkie-talkie in his hand, and after a while, when the sun completely jumped out of the horizon and the sky was bright, Yang Yifei whistled: "Shhh......h

As soon as this hurried whistle sounded, the snipers and heavy machine gunners snapped to their feet and immediately entered their combat positions.

Yin Zhiping, the leader of the makeshift sniper squad and one of the eight snipers, set up his own sniper rifle.

Yang Yifei ordered: "Sniper, the bed crossbow on the female wall of the target, try to hit the position of the bow arm, scrap them for me, pay attention to the coordination of the shooting target, and try not to have several guns against the same target." ”

Hearing Yang Yifei's order, Yin Zhiping ordered: "Take the first bed crossbow within the eastern visual range as the No. 1 target, shoot to the west in turn, everyone calculates their own target, and fires freely." ”

"Yes."

The other snipers responded in unison, Yin Zhiping's order was easy to understand, for example, if he was the No. 1 sniper, then his shooting target would be No. 1, No. 9, and No. 17.

Every time you add 8 to your own shooting target number, it is your own target, which can avoid wasting firepower to the greatest extent.

The lookout tower is 5 to 6 meters higher than the walls of Chang'an City, and even if the height advantage is reduced due to the distance, it is still in a condescending state.

Through the sniper scope, they can clearly see the scene behind the female wall, and it can be argued at a glance whether the bed crossbow was successfully destroyed or not.

After all, the bed crossbow is made of wood, which is incomparable with the armor equipment of later generations, and can be easily destroyed, provided that it can ensure accuracy.

Yin Zhiping quickly calculated the ballistic trajectory through the data displayed in the sniper scope, and said something in his mouth: "The distance is 1236 meters, the wind speed is 7.4 miles every half an hour, and the wind direction is ...... southeast wind."

With the calculation of the data, the crosshair slowly moved slightly and began to deviate from the target position, and long-range sniping at more than 1000 meters, except for a very small number of sniper rifles, basically aimed at the target position to fire, rarely hit the target.

After five months of study, the Quanzhen disciples naturally understood the concept of "meter", 1 meter is three feet and three inches, so they knew how to convert.

The sniper scope shows in English, the unit of wind speed is miles (mi), and the unit of time is hours (h), so there is no need to go into detail with them, anyway, the key to ballistic calculation is to calculate the point that the crosshair should aim at through those values, and the unit is not important at all.

So Yang Yifei only needs to tell them that mi stands for miles, h stands for half an hour, and m stands for meters.

"Bang...... Bang...... Bang......"

The dull gunfire of the anti-materiel sniper rifle rang out one after another, indicating that Yang Yifei's battle for domination of this world had officially begun.
