Wan Lin knows that this kind of light mortar is suitable for individual soldiers, the length is generally about one meter, the angle of fire is large, generally 45 °-85 °, the trajectory is curved, the muzzle velocity is small, the minimum firing range is near, the longest firing range is more than 2,000 meters, the killing effect on unprotected targets is good, and it is suitable for shooting at targets behind shelters and targets on the anticline.

He quickly moved the muzzle of his gun to search for the place where the fire was coming from in the distance, and from time to time there were clusters of shells from behind the hills, and the enemy artillery could not be seen at all. His heart sank, the enemy's mortar position was hidden behind the hills, firing using the principle of parabolic firing, and he could not stop the enemy's shelling at all.

He knew in his heart that the mortar was a curved artillery that used the seat plate to withstand the recoil to fire shells, and its characteristics were small size, light weight, simple structure, and extremely convenient operation. When firing, the barrel recoil energy is absorbed by the ground through the guò seat sheet. And when marching, the cannon barrel and seat plate can be decomposed, very easy to carry, especially suitable for mountain warfare and trench warfare, because it is the use of the parabolic principle of upward flight, the shooting almost does not have a dead angle, especially suitable for dealing with the target behind the shelter, has a great lethality to the stragglers Wan Lin really did not expect to grind the private army, but also equipped with this kind of weapon that only regular troops will be equipped with, which has to make him have a deep worry in his heart.

Fortunately, Cheng Ru and his people have been in battle for a long time, have rich battlefield experience, and their movements are extremely fast and flexible; as long as they judge the impact point of the shells in time according to the sharp whistling sound of the shells flying in the air, they can use their quick body skills and undulating hills to effectively dodge.

Although Wen Meng and Wu Xueying are two recruits, they will not be in much danger under the close protection of Cheng Ru and a few people, and with the explosion of fire behind Wan Lin, there are sounds of "woo", "woo", "woo" and "woo" in the air. "Watch out for shelling!" Wan Lin shouted into the microphone, and with a sniper rifle, he rushed to the side and backwards.

Flames erupted on the surrounding hills. Wan Lin lay down under the hill to avoid the explosive fragments flying in the air, and then against the "fluttering" falling rubble, he immediately stretched his sniper rifle back from the top of the hill, and a group of enemies were taking advantage of the cover of artillery fire, bending down and rushing towards his side.

Wan Lin immediately fired two shots at the swaying figure in the distance, "poof", "poof", followed by a string of fires on the hill where the side was strong, a string of heavy machine gun bullets whistling and flying backwards, followed by the two of them lifting their guns and withdrawing behind.

Wan Lin and Dali stopped and stopped in the back, covering their teammates who were quickly evacuating behind them. The enemy gunners hid behind the distant hills, and from time to time fired shells one after another at the front. The hills were filled with bursts of fire, and the debris and dirt that had been knocked out of the explosion "crackled" from the sky.

Gradually, the sound of the cannon gradually thinned out. Wan Lin lay behind the hills, put the sniper rifle tightly on the shoulder socket and stretched out the barrel from the side of the hill, quickly glanced at the hills on both sides through the sniper scope, and then aimed the muzzle of the gun at the pursuers behind. The enemy behind had been pulled away by a distance of about two kilometers under their effective blocking.

At this time, the enemy behind was carefully shuttling under the rolling hills, and he coldly looked at the figure of the enemy in the distance, and speculated: Just now, when they were attacking the top of the mountain, they had already fired a lot of shells, and now they are firing continuously, and the shells should be exhausted. The enemy was in a hurry this time, it was impossible to carry sufficient ammunition supplies, and the enemy's arsenal had already been bombed, and there was no source of supplies at all.

Thinking of this, a sneer appeared on the corner of his mouth, and then he turned his head to look in the direction of retreat. Not far away was the shadowy mountain shadow he had just seen, which had been clearly displayed in his sniper scope at this time, and the steep mountain shadow in front of him actually had a huge wedge-shaped gap in front of them, as if it had been split in half by a sharp axe that fell from the sky.

He was overjoyed that the direction of his retreat was at the foot of the two mountains, and as soon as they crossed the gap, they would immediately enter the undulating mountains ahead. At that time, a few of them could use their rich experience in surviving in the mountains to quickly get rid of these relentless pursuers.

He then lowered the muzzle of his gun and looked into the hills ahead. Hundreds of meters ahead, Cheng Ru and his men were quickly undulating in the hills, and they had approached the foot of the mountain in front, and the enemy outflanked on both sides showed no signs.

Wan Lin's heart suddenly relaxed. As soon as they left the hilly terrain and entered the steep mountains ahead, their chances of escaping their pursuers increased greatly. At that time, as long as they took advantage of the different terrain in the mountains, they could attack and retreat, and no matter how many enemies they had behind them, they were not afraid of them chasing them as long as they occupied favorable terrain.

He then turned his head to look at the strong force on the hill beside him, and saw that he was lying behind a long heavy machine gun, slowly moving the muzzle of the gun, watching the pursuers behind. He opened his mouth to order him to retreat quickly.

But at this moment, a fierce burst of gunfire suddenly came from ahead. Wan Lin and Dali were shocked, and the two of them turned their heads to look at each other at the same time. On the hillside on the right six or seven hundred meters ahead, a fierce gunfire suddenly rang out, and clusters of fire from the muzzles of the guns were sweeping condescendingly towards the hills with a rain of bullets; Immediately after that, strings of fire also appeared on the hillside on the left. On the hill where Cheng Ru and the others were, a sparkling fire immediately appeared.

Wan Lin and Dali's faces changed: they were about to rush across the mountain pass and enter the safe area, why did the enemy suddenly appear on the hillside in front of them? Completely cut off the retreat of several of his people, and the shape suddenly became extremely critical!

At this time, with the light of the fire spewed from the enemy's guns on both sides of the hillside, Wan Lin could see the mountain in front more clearly. Just now, I looked at the wedge-shaped gap that was just convenient for my group to retreat safely into the mountains, but now it seemed to be the open mouth of a giant beast, and the fires coming out of the mountainside on both sides of the gap seemed to be expecting my group to get in early and eat it in one bite.

Wan Lin's heart trembled: the retreat was sealed, and several of his people were bound to be tightly suppressed by the enemy in this hundreds of square meters of hills! At that time, I was afraid that a few of my own people would be able to fly out of this undulating hilly area in the rain of bullets and bullets from the enemy!

He quickly moved the muzzle of his gun to the black hills on the side, carefully observing the undulating hills on both wings, and was really afraid that the enemy would appear on the two wings again. If the enemy appears on both flanks at this time, then the enemy's encirclement has already been formed, and a few of them will be completely surrounded in this narrow hilly area, and there is no way to retreat!
