The boundary line of Xiangyun base is irregular, crisscrossing with the ruling area of Bai family. In the South and west of the base area, there are continuous mountains. They are not only tall and steep, but also long and narrow, with endless layers. Among them, there are many dangerous and important places, where one man is in charge of the pass and ten thousand people are not allowed to open.

However, the north and east of the base area are basically plains, and they are also granaries of the base area. They are flat, and are most suitable for the large group army to charge. The defense is very difficult, and they are very unfriendly to the defenders.

In view of this topographical feature, the Tianbing base camp put its heavy troops in the north and East, and gathered the first and second field corps, as well as 20000 troops directly under the base camp, all of which were pressed here, while the third field corps was stationed in the South and West.

Moreover, the base camp ordered the third field corps to drag all the enemies among the mountains and not let one enemy enter the hinterland of the base area! If serious consequences are caused by putting the enemy in, it should be dealt with seriously immediately after verification!

If the troops defending the north and East are really in a bad situation, they can take the initiative to let the enemy into the hinterland, but they must know how many enemies they put in. The number must be accurate, and the error should not be more than 100 people!

After the mobilization of the heavenly army, within half a day of the troops entering the position, the Scouts of the officers and soldiers had contact with the garrison, then the vanguard of the officers and soldiers, and then the big troops behind them, surrounded by the surrounding areas of the Xiangyun base, the flames of war spread everywhere!

That night, there was no light.

Under the cover of the night, a troop of more than 7000 people quickly passed through a plain to the north of the base area.

This unit is a special brigade directly under the headquarters of Tianbing, with a total of 7000 people. Although the number of soldiers is not large, they are among the elite of the heavenly soldiers. All the soldiers in the troop are above the realm of great achievement, not even a realm of small achievement.

The team was led by Zhou Xianguang himself. Because the next battle was very important, Li Qingyu also temporarily followed the team.

The advance speed of the troops is very fast, although in order not to make any noise, no one is riding, but their running speed is no less than the galloping horse!

About an hour later, they arrived at their destination. No one stopped to have a rest. They all untied their engineering shovels from their backs and began to dig foxholes.

This is a vegetable field. Potatoes are grown in it. The soldiers were very careful when digging the foxhole. They first removed the potato and the soil from the root, and cleared out a circle about 80 cm in diameter. Then they began to dig down. The soil was evenly sprinkled under the potato, so that no one could see any clue.

After about one meter of digging, he stopped digging and got into the foxhole. Then he covered the prepared shield on the parachute pit. Someone came to help cover the shield with soil. Then he moved the potatoes back to the original place. The leaves of the potatoes were also arranged, as if nothing had moved.

The distance between each two foxholes is about 20 meters. There are 7000 foxholes, spreading out a large area.

Even when people were working hard, no one said a word, the whole position only saw a vague shadow moving, although busy, but orderly!

When the day was about to dawn, everyone hid in the foxhole. The last few soldiers were disguised by Li Qingyu and Zhou Xianguang.

Li Qingyu and Zhou Xianguang didn't dig a foxhole. After everything was done, they walked to a small mound not far away and looked around to check the people's camouflage. If there were any flaws, they immediately corrected them. They didn't stop until they couldn't see any flaws in their eyes.

Although the night is like ink, they are both high-level warriors with the ability to see things at night.

When everything is done, Zhou Xianguang can't help feeling.

Yesterday afternoon, they received intelligence from the reconnaissance forces, saying that they found enemy scouts in this generation, and then found about 3000 vanguard troops of the enemy. It was judged that 100000 of the enemy's large troops might want to enter the base area from this area.

At that time, Li Qingyu happened to be with Zhou Xianguang. They quickly reached a consensus that they could not let this enemy in!

Just in the morning, they received intelligence that 500000 enemy troops had been put into the base areas. If we continue to put people in, Deng Yuqi and Gu Tianxing will be under great pressure.

After all, the combat effectiveness of the reserves and the militia is one grade lower than that of the field soldiers.

They must stop these 100000 people at all costs!

But now all the troops have taken over the enemy, and the fighting is so fierce that they can't spare any manpower to stop the enemy. What's worse is that an army directly under the base camp has also taken over the enemy, and there is only one special brigade in hand, 7000 people!

Although the special brigade has strong individual combat capability and is the best steel to support other troops, it is a little mysterious to meet 100000 people in the front! The huge advantage of the enemy's number will suppress the heavenly soldiers and make them unable to give full play to their strength.

If the enemy forms a formation and rushes to the special brigade like the tide of the sea, it will be difficult for the special brigade to kill the enemy!

Moreover, the enemy has a military God camp, with a total of more than 300 people! This is also a huge force!

However, the situation forced, can not stop also want to stop! If you can't stand it, you have to!

Death must be stopped! Die!

After receiving the information, Zhou Xianguang and Li Qingyu immediately came to observe the terrain in person. Zhou Xianguang looked at a flat, green vegetable field, his brow immediately wrinkled.

It's almost impossible to finish the task!

Unless they can make an ambush and suddenly appear in the enemy's ranks, each soldier can kill five to seven enemies in the first time, and the enemy has only 50000 or 60000 left, so they can kill this enemy completely and easily.

But the terrain here is so flat that it's not suitable for ambush!

"What's the matter? Is the enemy cunning enough? Having chosen such an offensive route, our team can't ambush in such an environment! " Zhou Xianguang could not help but make complaints about it.

Li Qingyu, however, said with a smile, "hey hey, boss Zhou's words are not so good. Who says this kind of environment can't ambush?"

"How to ambush?" Zhou Xianguang asked strangely.

"It's flat here. There's no shelter. We can't ambush on the ground, but we can ambush underground!" Li Qingyu said with a smile.

"Dig a tunnel? It's too late. " Zhou Xianguang blinked and said.

"What are you doing digging tunnels for? It's no use saying it's too late. How many exits is the tunnel? We let the soldiers hide in the tunnel. How can they all come out in an instant? " Li Qingyu said.

Zhou Xianguang's eyes suddenly brightened. He understood Li Qingyu's meaning and blurted out: "foxhole!"

Li Qingyu snapped his fingers and said, "the enemy is the foxhole!"

Foxholes are very practical in hot weapon operations, and can effectively protect themselves, but they are almost useless in cold weapon operations. You can shoot in the foxhole and kill the enemy. You can't wave a knife at the enemy in the foxhole, can you?

Because of this, Zhou Xianguang, a tactician, didn't think of the foxhole tactics for a moment. When Li Qingyu reminded him, he remembered it.

In a few words, the two men worked out a battle plan.

They first put the enemy's vanguard directly in the past and ignored it. After the vanguard passed, the special brigade took advantage of the night to move to the battlefield and completed the ambush unconsciously.
