"It seems that I can't fight anymore! It's okay, it's okay!" Zhu Ling spat a mouthful of phlegm, then laughed twice, "Send the order, double the sentry tonight!"

Above Tongguan, there are wolf smoke like a pillar.

Under Tongguan, Cao's army retreated in a panic...

...

...

"Did the young master understand today?"

As Zhu Ling expected, after the first time Cao's army saw the roar of cannons, they soon lost their fighting spirit and didn't even pretend to behave, and they just retreated by ringing gold.

The one-day tour of Tongguan for the youth tour group was a successful end without any danger.

Others only burn firecrackers in the New Year, but they watch big fireworks and big firecrackers in the New Year, so they naturally feel completely different.

On the way back, these young people were very excited and couldn't help but whispering to each other, commenting on what they saw and heard today, and using this to demonstrate their courage and wisdom.

No one noticed that there was a person who kept silent from beginning to end.

Everyone thought that the core of this youth tour group was Pang Hong, but in fact it was not. Fei Zhen, who was wearing a simple costume and was silently mixed in the queue.

After returning to Chang'an General's Mansion and taking a simple wash, Pang Tong asked Fei Zhen to see what he had gained today.

Young people like to play, and Fei Zhen is no exception.

『Architecture!』 Fei Zhen said, 『My father said that artillery will change everything in war! The attack and defense weapon is nothing more than thunder and thunder!』

Pang Tong rolled his eyelids, "That's all?"

Fei Zhen smiled, "Of course not. Why are artillery powerful? The four peoples are strong, so they can get the country's strength. Only when the country is strong can they have the power. Without scholars, they don't know what to do, without farmers, they don't know what to use, and without merchants, they don't know what to do. Only when the artillery is involved in the four people can they get the benefits."

Pang Tong nodded, "Is there any more?"

『There is still someone.』

Fei Zhen nodded and said, "This time, the Tongguan list is all children of officials and gentry in Guanzhong, Chang'an. On the one hand, it can be seen in its name, but on the other hand, it can also strengthen people's hearts..."

Pang Tong smiled a little.

If there is no big accident, the children of Guanzhong officials and gentry will become Fei Zhen’s future talent reserve database. It is very important to have an impression first, so when Pang Tong revealed the meaning of this youth tourist group, even if the preparation time was very short, almost all the officials and gentry sent their children to Pang Tong’s mansion on time and on time, and they also explained it repeatedly to make these children obedient.

Tongguan is a battlefield, but Pang Tong is not stupid and will not take his children to fight for his life on the battlefield. So basically there are risks, but the risks are not very high. For most brainy officials and gentry, they all know what this grouping represents...

Originally, they might have said that who was from Jingxiang, who was from Longyou, or who was in the north before, but now they all belong to the same team. Of course, just such a youth group did not have any decisive role, but it was the beginning of integration. With more similar activities later, the original factions in Guanzhong will slowly disappear as these young people grow up and merge into one.

In addition, as Fei Zhen said, although Cao's army was not allowed to enter Tongguan, would the people of the Three Guards of Guanzhong be affected at all?

Obviously it is impossible, but it seems pale and powerless to issue announcements. Let the children of Guanzhong officials and gentry go to Tongguan for a walk, and the news brought back can make these Guanzhong officials and gentry put their hearts back.

Three rounds of artillery, Cao's army collapsed.

There is no bloody scene that scares these young people who are not yet fully mature in their minds, but will increase their confidence in fighting against Cao's army. Although these young people may not have the right to decide now, the seeds planted may bloom one or two gorgeous flowers in the future...

"All these are good." Pang Tong said affirmatively, "So, do you have any other ideas?"

『Other thoughts?』 Fei Zhen subconsciously repeated, 『What else did I neglect?』

Pang Tong nodded, "In addition to what the young master said just now, there are at least three points. However, if you only say two more points, I will give you an excellent evaluation in your policy today...How about it?"

『Cao Army's military force?" Fei Zhen said tentatively, 『Cao Army's morale has obviously fallen, but it still persists... Or do you not know that the Hedong strategy has fallen, maybe it is because there are other support? No, this is actually the same question, what is Cao Army waiting for...』

Pang Tong smiled and said, "Yes. These are one point. What about the other two points?"

Fei Zhen felt her head was getting bigger.

Did he miss something else?

Tongguan, battlefield, soldiers, flags, transportation convoys in Tongguan inner city, then Cao Jun camp on Niutouyuan opposite, Cao Jun soldiers who fled in panic, and Cao Jun soldiers who were destroyed and abandoned in Tongguan Sakura Road...

『Ah! Ha!』 Fei Zhen clapped his hands, 『I thought of it! Supply! Is it consumption and supply right?! War requires consumption every day! This is also a question that the commander must consider! How much consumption is, where does the supply come from! Cao's supply line is longer than us, so they are more likely to have problems, right? Is it Wei Wen long?"

Pang Tong laughed loudly, then stood up, "Today's theory, the young master has gotten better... but there is another point, I hope the young master can come up with it too..."

What is another point?
