In addition to supplies, the entire Zhenbei Army and the Five Armies quietly converged in the northern defense line......

Since it had been learned that Chen Guo and Wu Guo were going to do something in the hot summer weather, General Huo Da naturally would not sit idly by. At the same time as a large amount of saltpeter was transported, the two armies that were on 'leave' were also transferred, and the total number of soldiers of the five armies exceeded 50,000.

And General Huo Da, Zhang Ru and others naturally came to the front line in person.

But none of them were exposed, but at the suggestion of Lin Zifan, they disguised themselves as ordinary soldiers, and only waited for the war to break out, and suddenly broke out, giving Chen and Wu Erguo a 'surprise'!

But even so, in the last dynasty two days ago, the empress still felt not very relieved, after all, it was the two countries that joined forces, and the population of Chen and Wu was several times more than that of the Tang Dynasty, 50,000 soldiers, even if she could win, she would lose a lot.

However, the three armies of Zhennan, Zhendong, and Zhenxi all had their own tasks, and the surrounding countries were eyeing each other, and they could not spare too many troops to help each other, so they could only think of other ways.

To this end, the empress waved her hand and asked the logistics officer Lin Zifan to take out all the sanitary napkins that had been made and handed over to the household department for storage in the treasury to assemble the Zhenbei Army!

In the past few days, the sanitary napkins produced by the Logistics Government have exceeded 200,000 pieces, and it is naturally far from enough to assemble the entire army of the Tang Dynasty, but if it is only to assemble the Zhenbei Army......

There are only 60,000 officers and soldiers in the Zhenbei Army plus logistics personnel, and even if everyone is divided equally, everyone can get about four pieces. One piece a day is enough to survive most of the month.

What's more, it can't be that everyone has menstruation, right? Even if it is calculated according to the average daily menstrual period, a quarter or even a third of the people have menstruation, it can last for more than half a month!

In half a month, the Tang Dynasty soldiers who have saltpeter ice to relieve the heat will not have problems in their mood or body, plus all the soldiers who come to menstruation can use sanitary napkins to maintain more than ninety percent of their combat effectiveness......

Besides, it can't be as long as half a month.

The Tentrai Mountains are named because they stretch between the two countries and seem to be hanging down from the sky.

Above the mountain range, it was quite cool, and at this moment, several spies of Chen and Wu were hiding in the dark, looking at the Tang camp from a distance with something similar to a telescope.

In the camp, the Tang soldiers were listless, many of them were sweating, and several of the people standing guard under the scorching sun were even fainted by the sun.

It's not that the Tang soldiers are not strong enough, but in order to deal with battles that may break out at any time, soldiers must wear battle robes and armor during their duties.

But under the 40-degree heat, he still wears a heavy armor that is not breathable, and those who stand guard must be exposed to the sun...... I can't stand it even if it's strong.

The world of high martial arts, after all, is not a fairy world or a fantasy world, although everyone's strength is strong, it is still in the human realm. What's more, ordinary soldiers are not invincible masters in the world......

Because of this, every summer, although the number of battles is very small, the casualties of the Tang soldiers are more than the other three seasons combined!

Hot, sweaty, from time to time people fainting, listless......

This is what the spies saw, and then, they quietly left, reporting to their superiors, who quickly whipped up and reported to the two generals of Chen and Wu who were in charge of the battle.

After the two generals got the news, they looked at each other, and they were all elated.

"Hahaha, the strategists really didn't miscalculate, not only has it not rained in the past three days, the weather is getting hotter and hotter, those southern barbarians, they can't hold it anymore!"

Chen Guo's famous general-Chen Fa laughed and geared up!

"In that case, let's order to go down, let the soldiers eat and drink enough, and at noon today, break the northern defense line of the Southern Barbarians!"

General Wu Mei sneered, murderous.

As the orders of the two were conveyed, the soldiers of the two countries acted instantly!

Although the temperature on their side has also reached about 35 degrees, and it is also very difficult to put on the armor, it is still too different from the high temperature of more than 40 degrees in Datang!

At least, the soldiers of the two countries were not sunburned.

Although it is only separated by a Tiantuo mountain range, the temperature on both sides is very different. There are six or seven degrees!

At noon, the weather is at its hottest.

In the camp of the Northern Army in Datang Town, there were wisps of smoke everywhere, and some soldiers were enjoying the cool in the corners of the tents, but even so, they couldn't stop sweating, and they were listless.

Even if the meal was ready, the soldiers had no appetite, and they looked helpless with the food, and almost didn't eat much......

After seeing this scene with their own eyes, Chen Fa and Wu Mei were even more excited, and immediately ordered: "The whole army attack!

Come on!

The soldiers of the two countries suddenly appeared, which can be said to be all over the mountains! The nearly 500,000-strong army was by no means child's play, and they rushed towards the camp technology of the Zhenbei army with weapons in hand!

"Enemy attack!"

In the Zhenbei Army, a sharp shout sounded, and then, the soldiers of the two countries suddenly found that those soldiers who were originally standing guard and should have stood up for defense as soon as possible turned around and ran!

"What's going on?" Chen Fa looked confused, although she naturally looked down on these Southern Barbarians who only had muscles in their heads, she also had to admire their bravery.

Especially when it comes to fighting, they are very violent, and there will never be deserters.

But now, all the hundreds of people standing guard have run away, and the soldiers who were enjoying the cool have all disappeared in an instant......

"Is there a deception?" Wu Mei's heart tightened, and then she sneered again, and said to herself: "It must be that she is in a bad state, and she knows that she can't beat us, so she is ready to retreat a distance first, organize a defensive formation and then engage us!"

"Keep rushing, rush at full speed!Don't give them a chance to form a defensive formation!"

She gave the order, and the herald immediately shouted at the top of his voice, telling the soldiers of both countries to rush at full speed.

However, at this moment, Wu Mei was suddenly confused.

Because, in her opinion, the Tang soldiers who had to retreat a distance in a panic, and were chased and killed like dogs by the two of them, did not retreat an inch!

On the contrary, among those tents and simple houses, a large group of soldiers rushed out, and at first glance, there were nearly 50,000 of them!

"Oh? The five armies of the Zhenbei Army have arrived? What kind of news have you got! Unfortunately, 50,000 people are not enough!"

Chen Fa sneered, if it was in other seasons, the five armies of the Zhenbei Army would be together, and it would indeed be treated with caution. But now it's summer, and the temperature in Datang is over 40 degrees, and 50,000 people can exert half of their combat power, thank God, not to mention that at least 10,000 of them have come to menstruation, and their combat power has been further reduced?

Chen Fa has even seen the picture of his soldiers galloping in the territory of Datang after breaking the Zhenbei Army!
