According to Kotaro Nakaya's experience, the Optimus Army should have run away, so he first asked the mortars to wait for the bombardment again, he personally led people to the mountain pass to observe, and sure enough, there was no movement in the opposite position, and they came to the outside of the mountain pass to make sure that the trench was empty.

Ran again! This situation almost made Murakami Kaisaku angry, this Optimus Army was simply too slippery, they almost always took advantage of the advantage and ran, so he immediately ordered the whole army to pursue, the 231st Wing in the front, the 232nd Wing in the middle, and the 233rd Wing dragged back and quickly passed outside the mountain pass.

When the 232nd Wing passed through the mountain pass, suddenly two earth-shaking explosions broke out in the sky above the devil's head, and suddenly the sky suddenly darkened, followed by large and small rocks falling down like raindrops, and the devils in the mountain pass had nowhere to hide, and the mountains and rocks fell and buried thousands of devils in the rubble in an instant.

"They planted explosives on the mountainside!" Keisaku Murakami almost fainted when he saw this scene, and they could also think of such a solution.

The falling rocks lasted for about three minutes, and the dust in the sky gradually dissipated, and then looked at the mountain pass, which had accumulated stones that were almost two people high, and under these stones, most of the officers and soldiers of the 232nd Wing were pressed underneath.

"Help! Help! Murakami ordered,

The survivors of the 233rd Wing and the 232nd Wing all began to move away from the stones to save people, and the 231st Wing, which had already passed through the mountain pass, also turned back to help those who were injured and not buried, and before they could understand what had just happened, countless mortar shells rained down outside the mountain pass, and the explosions were continuous, and the devils of the 231st Wing had nowhere to hide, so they all had to lie on the ground with their heads in their hands and did not dare to move.

After five minutes, the explosion finally stopped, and the devils stood up one after another to check on their companions around them, and at this moment, hundreds of people suddenly appeared in the trenches on both sides of the mountain pass, which had been empty before, and light and heavy machine guns, submachine guns, grenades, grenades, and grenades beckoned towards the devils in the mountain pass, and the devils were shot and fell to the ground in panic.

The main force of the Qingtian Army quickly returned to the trench under the cover of the explosion, and attacked again after the explosion, although there were only more than 500 people, but because of the powerful firepower of the weapons in their hands, the 231st Wing at the mountain pass was killed and wounded in less than two minutes, and the devil lay on the spot and used the corpse of his companion as a cover to counterattack, which was useless, the devil kept being shot, and the gunfire of the devil counterattack at the mountain pass became more and more rare.

The Japanese troops who were still in the valley heard the fierce gunfire in the mountain pass but could not do anything, and the rocks separated them from the 231st Wing, and under the rocks were thousands of officers and soldiers of the 232nd Wing.

"Remove the stones! Fast! Fast! "Bringing rocks can not only save people but also support the 231st Wing, and Murakami already feels that something is wrong.

The gunfire outside the mountain pass stopped, and Kotaro Nakaya knew that the 231st Wing would definitely be finished, and he didn't dare to imagine that it was the 231st Wing that wiped out the Optimus Army, and Keisaku Murakami thought the same as he thought.

"Big brother! All the devils outside the mountain pass are annihilated! Qi Rui said happily to Qin Tian,

"How many?" Qin Tian didn't participate in the battle, he studied the next tactics later, he just wanted to go to the battlefield now, Qi Rui wouldn't let him go! The Optimus Army is here today because of the boss Qin Tian, anyone can be sacrificed, but the boss can't, because if he were to do something, the Optimus Army would probably be gone!

"Less than two thousand! But this should be a wing, but it's not full! It should be a part of the loss in front! Qi Rui speculated,

"Let the brothers quickly clean up the battlefield and we will go back!" Qin Tian ordered,

"Yes!"

The Optimus Army simply cleaned up the battlefield, mainly with light and heavy machine guns, mortars, grenadiers and bullets, and then marched back to the outside of the first station.

Looking at the sky, Qi Rui asked, "Big brother!" Will these devils spend the night in the valley? ”

"They have a lot of wounded and shouldn't be able to go! I just received a telegram that now the Fourth Division has been blocked by the southern Anhui guerrillas near Qi County, and they will definitely not be able to pass, and I estimate that the three wings of the 39th Division still have at most half of their strength left! That's about 5,000 devils! Our next goal is to kill as many as we can, but it depends on what the devil does next! Qin Tian knew the phrase that the trapped beast was still fighting, and he was worried that the devil would cause great losses to the team when he counterattacked without fear of death.

"Big brother! If only we could lure them out of the second station, the fortifications over there are all in good order!" Qi Rui said,

"The devils shouldn't dare to chase after us, what we can do now is to continue to stimulate and tease them, although these bunkers, bunkers and trenches have been bombed, they can still be used, we can make good use of them! We'll toss them around after dark! ”

The best thing the Qingtian Army is indeed best at fighting at night, and for this reason, Qin Tian has made everyone fully prepared.

"Big brother! The rocket you let us prepare is ready! Han Zhang said,

Qin Tian said to Lin Ke's brothers and sisters: "Lin Ke! Lin Nan! You guys continue to be in charge of rocket launches! We're still using the same methods as before! ”

"Yes! Eldest brother! "Lin Ke and Lin Nan are the instructors of archery in the team, and Han Zhang's archery skills are better than theirs, but he is busy.

"Qi Rui! How many were wounded this time? Qin Tian still asked his least favorite question.

"More than thirty wounded, twelve of them seriously wounded, we lost twenty-six brothers!" Qi Rui said a little sadly,

"They're all heroes! Don't be sad, everyone! As long as it is a war, it is impossible to do without sacrifice! What we have to do is turn our grief into strength, continue to kill the enemy, and avenge them! But I still have to warn you! Be sure to protect yourself while killing enemies! Because whoever sacrifices is a huge loss! Because you calculate how many of our devils will die if one of us dies! If you live, you can kill more devils! Protect yourself not because you're afraid of death! It's for more devil killings! ”

"Yes! Eldest brother! We must protect ourselves! "No one is sad because everyone is ready to sacrifice.

Thousands of devils spent most of the day digging out the devils buried under the stones, many people were smashed into meat sauce, Murakami Kaisaku led the army to the outside of the mountain pass, and saw the corpses in one place, the 231st Wing was wiped out and no one survived!

"Division Commander! The 231st Wing is all shattered!! ”

Murakami wiped away his tears sadly, and only then did he understand why Commander Okamura had sent two divisions to exterminate the Optimus Army, which only had a few hundred men, and finally understood why Kotaro Nakaya was so cautious!

"Division Commander! It's going to be dark soon! We must evacuate here! Kotaro Nakaya said,

Murakami Keisaku also wanted to leave, but looking at the so many wounded people around him, he said helplessly: "How can we evacuate with so many wounded!" Are you going to let me leave them alone!? ”

"But! What the Optimus Army is best at is night fighting! It's dangerous for us to stay here! Kotaro Nakaya said,

Murakami Keisaku looked left and right and ordered, "Immediately withdraw to the valley!" Build fortifications out of the stones here! Tonight, we will fully defend against the night attack of the Optimus Army! ”

The devils retreated to the valley and built a bunker with the stones of the mountain pass, because they were afraid of a sneak attack by the Optimus Army, they built stone walls on all sides, and there were clever devils who used the stone cracks as a hole to prepare for a big battle with the Optimus Army, so as to avenge the dead.

All of this was clearly seen by the scouts Han Zhang and Chai Leopard, who used binoculars.

"Big brother! The devils were [3Q Chinese] cautious, and they built cover out of the rocks that had been blown down, which would have been a great struggle if we were to storm it. Han Zhang said,

"You mean the devils built fortifications with those stones?" Qin Tian asked with a look of surprise when he heard this,

"That's right! Is there a way for Big Brother to them? ”

"Isn't the devil stupid!?"

"Huh!?" Han Zhang didn't understand what Boss Qin Tian meant, so he could only build fortifications, but he was stupid.

Qi Rui smiled: "Yes! If the rocks are blown apart, they will increase their casualties! This commander is a mallet! ”

"Big brother means to bombard them with mortars?"

"Because it is a temporary bunker, the stones are just piled up, and once bombed, these stones are blown away by the blast wave, which is equivalent to the effect of artillery shrapnel, and even greater than the damage of artillery shells! Little devil, this is death! ”

If it is an ordinary team, it can't help the devil's bunker, but this is the Optimus Army, not only mortars, but also four anti-aircraft machine guns, four mountain artillery and other heavy weapons, in order to eliminate these devils, Qin Tian did not hesitate to use all the shells.

"Most of the rocks they picked up were the size of human heads!"

"That's for sure! Because they can't move it because it's too big, it's just two people moving it together, and the stone won't be so big, and the blast wave of the cannonball can blow the stone away! After Qin Tian finished speaking, he immediately ordered: "Gather all the mortar shells, and also get the four mountain artillery guns that were captured before!" ”

Qingtian Army moved all the family background, and when they were all ready, and it was getting dark, Qin Tian immediately ordered all kinds of artillery to be in place, the terrain in the valley Qin Tian was too familiar, and he personally supervised the adjustment of the firing range.

"Mortars ready!"

"The mountain cannon is ready!"

"The grenadier is ready!"

"Good! Brothers! Aim at the enemy position and up! ”

In the valley, Murakami Kaisaku sat behind a stone bunker and hung his head worried, he had already sent a request for help to the Fourth Division, but they were still near Qi County, even if they were on the road until noon tomorrow.

"Division Commander! Why don't we find a place to hide! ”

"Where can we hide?" Murakami Keisaku suddenly looked down on Kotaro Nakaya and them, feeling that they had been frightened by the Optimus Army.

"Division Commander! I have a feeling that the Optimus Army will definitely attack at night, and possibly use mortars, these fortifications are relatively simple! I'm afraid they won't be able to withstand the bombardment of the Optimus! ”

"And where do you feel safe?"

"There's a cave over there, which should be used by the Optimus Army to store food! We can go inside and take shelter! ”
