It was said that it was a general attack, but in fact, the pool was dug for more than two days. After all, it was large enough, and it had to avoid the four or five hours at noon. By bringing in the water from the Qinghe River, it was at least a huge pool.

It took more time to prepare saltpeter at the same time, five days, and in this blink of an eye, the summer solstice has passed.

"Actually, Zuo Feng has returned to Luoyang, right?" Liu Tao put on armor, or forced himself to put on armor.

The temperature is about 30° to 35°, which is very fatal in the era without air conditioners and electric fans. It was already very difficult to wear armor without armor, but wearing armor was like a steamer. I thought that after a while, the armor sheet became hot under the sun.

It is absolutely necessary to add: "If someone told me that I would wear a piece of armor to fight in such a weather, I would definitely feel that the other party was crazy!"

"That's also the matter after the sun becomes fierce." Lu Yan replied, "That's why my father asked us to get up at Yin and start the general attack after halfway through Mao and hour."

The general attack was launched at 6 o'clock in the morning. It was just dawning, and it took five or six hours before the sun was completely rising.

Can you capture the city in five or six hours? To be honest, I feel unsure. After all, Guangzong is close to Qinghe, and like Xiaquyang before, there is a moat.

I can only say that fortunately it was not a strong attack, otherwise how to deal with this moat would become a problem.

"I just didn't expect that the teacher actually put the digging soil into a sack. This method of using local materials is really clever." Liu Tao sighed.

The most clever thing about Lu Zhi was that he originally planned to dig soil to build a pond, and then pour saltpeter into it to create ice water. Relying on ice water to cool down the soldiers and ensure that the soldiers can maintain their state to attack the city.

But I didn't expect that the digging of soil could be used to fill the moat... Sure enough, it was not a waste at all.

"If you guess correctly, there is probably another reason." Lu Yan thought for a while, "When I prepare, I think I will probably know... By the way, brother will also take the lead in charge this time?"

"No, no, no, only Shangguan Yu, Liu Ge and Guan Yu's troops participated in the battle. Zhang Fei led his troops to cruise outside, and it was enough to catch fish that had missed the net. I was in the middle and there was no need to go into battle in person." Liu Tao shook his head.

If the generals under his command command troops to fight alone and beyond his sight, the defeated enemy troops will not be considered his experience. Similarly, the magic will naturally not take effect if the army is not under his command or the army that is not in his sight.

Recently, a remedy was found, which was to use the "Wind Dragon Insight" to achieve long-distance control. But there is a major premise that he must be in charge and cannot let the generals below command the troops alone.

After all, he was not confident whether this would cause the magic to fail. Before proving that there was no problem, he had to command it 'in person'. Otherwise, it would be a bit weird to find that the magic would not work and then temporarily ask to take over the command power.

"It's okay if you are in the center. If you can, your brother would be better not to get too close to the city wall." Lu Yan was a little relieved when he heard this.

At the time of Mao, the whole army began to gather, and the breakfast had already been eaten, which was more abundant than usual.

Liu Tao originally planned to try to make cold skin, but soon realized that bean sprouts and cucumbers had not yet. That was all, cold skin without aged vinegar and spicy oil was soulless.

"The whole army, move towards the other side of the pool!" Lu Zhi ordered the army to move forward.

It can be seen that the enemy troops had already discovered the gathering of officers and soldiers on the walls of Guangzong City and began to prepare for war. Some firewood smoke could be seen vaguely, as if something was burning.

"It should be golden juice, right?" Liu Tao thought for a while, and then threw this idea out of his mind. The scalds can be solved by healing and vitality regeneration, and bacterial infections can be solved by purifying light.

Of course, only for his soldiers. His magic was useless in the divisions under Lu Zhi. In fact, as a while ago, he used the magic of "burning will" on other armies.

After all, the army is not tired of war, so we should improve our morale and launch a general attack while the weather has not yet become completely hot. Even if we cannot participate, we can support it later. It is better than just waiting for Zuo Feng to come here like this.

Who knows it's useless, yes, his magic will not work for other armies except for his troops.

Obviously, by default, other troops are not considered to be under his command, so they are judged to be ineffective in determining the magic effect. Only the troops under his command will have effect.

If he hadn't had this experience, how could he have personally gone to the battlefield to be on the safe side?

When we arrived at the pool, there were soldiers from specialized baggage troops who scooped up the water from the pool and sprinkled it on the entire army. This made the armor pieces and the clothes inside the pool cold water.

It was cold and the temperature was below ten degrees. To be honest, it was still surprising that water at this temperature appeared in this weather. However, I have to say that although it was a little cooler, after watering it like this a few times, the whole person suddenly became much more refreshed.

But the next thing is not that wonderful...

"Bao, bah, bah, bah... why do you splash soil at me?" Chunyu Qiong started cursing, feeling happy. Who knew that he would not splash water suddenly, but instead poured soil. He was covered in mud, dirty and uncomfortable.

"To prevent arrows?" Yuan Shao looked at Lu Zhi with no expression on his face.

"It's not like that." Lu Zhi replied, "The purpose is just to prevent the nails from getting hot when shining by the sun... just click it!"

The subsequent part is not just soil, but also ripe lime. The whole body becomes white and ugly. However, the white one is less absorbing the sun's light than the black nail, causing heat.

"It seems that many things, although everyone has not figured out the principle, at least they know what the effect will be." Liu Tao sighed to Guan Yu beside him.

"So, brother knows the principle?" Guan Yu asked curiously.

"I know, but it's difficult to explain. I'll tell you if I win, how about it?" Liu Tao replied, but just finished speaking, and couldn't help but wonder: Is this considered raising a flag?

Fortunately, Guan Yu was not confused, and silently watched others pouring mud and lime on himself, and his whole body was colorful. Liu Tao saw it, but he felt an inexplicable sense of familiarity. After all, this tone is very similar to camouflage.

"Each person has a glass of ice water, and set off immediately after drinking it!" Another soldier from the Fire Head Army brought bowls of ice water over.

"Why is this water so bitter?" I was the first to drink it and felt that the ice was ice, but it didn't taste very good.

"It's good to drink ice water, why are you complaining about?" The officer next to him drank it all, and then cursed.

The other soldiers also knew this very well, and didn't talk nonsense, and drank it dry. They felt a sense of coldness from their throats to their stomachs, and their hearts were suddenly cold. For a moment, they actually forgot about the hot summer heat.
