Under the heavy night, the silence was broken, and the vanguard unit connected with the mechanical beast troops gushing out of the valley.

The barrage immediately covered the slightly narrow valley entrance. The mechanical beasts rushed out of the valley with their teeth and claws, while some rushed down from the gentle slopes on both sides and rushed towards the front of the adapted army.

Unlike the previous desperate resistance, the hexagonal formation in front did not retreat as if it was fighting in the hills. It could not hold on until it could not hold on. This time, the small formation in front was almost done, that is, when the mechanical beast was about 15 meters and was about to approach the warriors in the small formation, they would quickly retreat while covering and retreat from the gap between the three small formations behind them. While retreating, the soldiers quickly changed the magazines, and then flushed in the team behind them to regroup into a small formation.

The hexagonal array behind did not rush forward, and protected the retreating comrades on the spot while resisting the approaching mechanical beast troops. At a safe distance of 15 meters, they would resolutely disperse and retreat like the small array in front, without giving the mechanical beasts a chance to get close.

From a high point, the black mechanical beast group was like a turbid wave, surging towards a bright dragon's head and face. However, this headless dragon was not afraid at all and wedged into the turbid current, but was not overwhelmed by the turbid current, but avoided the wave, but refused to retreat.

After more than ten minutes, although it seemed to be getting farther and farther away from the Wolf Valley, no one died in the human army, and the Mechanical Beasts troops were slowly pulled out of the Wolf Valley. Along the way, hundreds of Mechanical Beasts fell to death due to excessive shots.

Gradually, the number of mechanical beasts and came out has dropped drastically. Obviously, it is not cost-effective to fight against humans like this.

However, there is no way out on the battlefield. The mechanical beast group has a tendency to retreat, but the adapted army has a goal. When they retreat, I advance. Youlong bit the tail of the mechanical beast group's retreat and advanced towards the Wolf Valley again.

The mechanical beast group was unwilling to give up and began to fight out of the valley again. The adapted army retreated again, and the two sides began a tug-of-war.

Many people in the adapted army have attended military academies and understand that this is the two sides entering the strategic stalemate stage. No matter what the reason for the two sides entering the strategic stalemate stage, this is good news. At this moment, someone is reincarnating in teams, eating food to replenish their physical strength, bandaging their wounds, and happily greeting their teammates. There has been no such situation for a long time. Resisting the mechanical army, the casualty rate is close to 0, which is like giving all the soldiers a shot of stimulant. The battle has been going on for an hour, but there is no morale decline at all. Instead, the morale of the adapted army is still rising!

Finally, the mechanical beast army collapsed and completely retreated into the valley. At the entrance of the valley, a layer of mechanical beast corpses several meters high were piled up. This was the first time, there were no human corpses in the pile of wreckage!

The dragon did not pursue it, but stayed in place.

The moment the last mechanical beast limped into the valley, the adapted army burst into a shocking cheer.

"Please carry out the second command!" Wu Niu said expressionlessly.

Then there were personnel replacements. There were less than 10 people who died, and most of them were killed by stray bullets. Soldiers who were seriously injured lost their combat capabilities and naturally needed to retreat to the rear for treatment and were sent back to the base when they were retreating. However, such a battle was too satisfying. Many seriously injured soldiers actually begged the commanders of each small formation to desperately beg the commanders of each small formation, saying that they still had combat power and were unwilling to withdraw from the battle. As a result, the temporary rest time was forced to beg for more than ten minutes.

Bypassing the remains of mechanical beasts piled up into mountains at the entrance of the valley, the adapted troops entered the valley.

After entering the valley, no one did not breathe.

Here is hell. Whether it is the hillside on both sides or the flat ground in the middle that has been pushed by several explosions, piles of flames are burning. A small part of the fuel of the flames are trees, and more are fragments of the human body. The flames are all over the valley, some have burned out, and only a pile of smoke is still emitting ashes of sparks, and some are still burning, which is the sound of oil and water in the human body being burned out and ignited again. There is basically no gap between the fireworks, and they are connected in pieces, covering the entire valley in a sea of ​​fire.

"Along the path of the mechanical beast advancing, change the formation!" Wu Niu gave the order.

The third brother frowned and said, "But... there are flames everywhere, how can the new formation be unfolded?"

The new formation is cauliflower-like arrangement, which means that a 36-person small array is cauliflower-like arrangement, but the small array of the entire adapted troops is cauliflower-like arrangement. Overall, the troops entering the valley behind maintain a hexagonal small array, like the largest flower pole of cauliflower, and the six or seven small arrays have been transformed into the shape of 888822. The four most crowded sides face the hillsides on both sides of the valley, gathering together, just like six or seven small flowers growing on a large cluster of cauliflower.

This formation is designed at a glance to resist the impact force coming from both hillsides, but at present there is a sea of ​​fire in the valley. How can this formation be unfolded?

"Under the burning flames, there are heroes who died here. As a follow-up force, we have the obligation to bury their bodies! In addition, the flames, the flames in the sky at this time, are our excellent cover. If you don't hurry up and set up the formation, it will be too late when the flames burn out!"

The third brother slapped his head: "Yes! Why didn't I expect it? Mechanical beasts are full of infrared eyes. The flames all over the valley, they can't see our people clearly!"

The battalion commanders of each regiment ordered the reorganized army to use local materials to bury the bodies of dead comrades with sand and soil, while starting to change the formation in the valley and arrange troops. In fact, the mechanical beast could not find the way forward for the mechanical beast to advance. After thinking about it, the mechanical beast probably did not enter the flames at all, but chose to go up the mountain to the top of the hillside. The wind on the hillside was strong, and the fire was slightly larger than the fire in the valley. At a distance of hundreds of meters, the soldiers could see the mechanical beasts wandering anxiously behind the rocks while extinguishing the fire. However, the mechanical beasts were filled with light and could not go down the hillside at all, and could not enter the valley to attack. They were trapped on the mountain.

This made the soldiers feel very happy. They were happy. Some were laughing, some were throwing stones at the mechanical beasts, and some even roared at the mechanical beasts on the hillside, and ways to express their happiness were all in one go.

The happy short-lived, but long-suppressed release sometimes makes people willing to trade death for the capital!

When the flames burn out gradually, it is time for the war to break out again.

In the smoke on both sides of the valley, countless mechanical beasts flew down and issued the first round of impact after the battle outside the valley towards the adapted army that had completed the formation in the valley. The flames reflected on the body of the mechanical beasts, packaging these things into monsters that seemed to rush around in hell, and their teeth were sharp blades that tear everything apart in hell. At a certain point, the adapted army began to shoot. Looking down from the air, the entire adapted army was like a solidified cartoon explosion cloud, beginning to spit out bullets, flesh and countless metal fragments.
