There are differences in physical differences for everyone.

Even the same person will be different a few years earlier and a few years later. For example, Wei Du, the leader of another guard battalion who stayed in Chang'an, has obviously aged in recent years. The reason is very simple. Wei Du was seriously injured before, but although he survived, he also overdrawed his vitality. It was not very obvious at first, but later it slowly showed up.

Just like the annual rings of a tree, even if you don’t say anything, you can tell which year is rich and which year is poor.

Therefore, Fei Qian stayed in Chang'an and served as the guard of the Cavalry Office.

For long-distance travelers like the ones that are now, it is obviously more suitable for Xu Chu, who is younger.

Fei Qian took the cowhide water bag, first rinsed his mouth, spit out the sand and dust in his mouth, and then took a few large sips to relieve the burning in his throat.

The water in the cowhide water sac was sweet at the beginning, but soon after tasting the light salty taste, the subsequent sour and nitro leather taste also occupied the main flavor after the taste buds were activated, and the original sweetness disappeared.

Fei Qian returned the water bag to Xu Chu and burped it.

Without further development in materials science, leather water bags are still the best marching water reserve equipment. Bamboo and iron water bottles have been tested for a while, but unfortunately, they have all had one or another problems. They cannot be as soft as leather water bags, which can be carried, large in quantity and easy to repair...

That's right, if the water bag is broken, you can directly use Suijun's fish glue to apply leather, and then as long as it does not encounter heat, it will generally not melt.

Wood or bamboo kettles are OK when used at first, but one is heavier than cowhide water bags at the same capacity, while the other hand is broken and difficult to repair.

Iron or steel kettles also have this disadvantage. Moreover, if the current metallurgical production technology is hit by a delicate kettle alone, it will be no big problem. If the entire army is equipped, it will take too much effort. Moreover, even if the repair method is solved, the anti-rust work is not as simple as painting a few layers of paint. Otherwise, there would be no intention to use various aluminum products during World War II.

Therefore, even if Fei Qian has advanced ideas in his mind, he can only put it aside if his productivity cannot cooperate.

Just like Fei Qian is talking to people in the world about aviation planes, spacecrafts, flying out of the solar system, conquering the stars and the Milky Way, etc. Nowadays, people in the world and even the whole earth will not think that Fei Qian’s idea is a wonderful idea or a great guide, and will only think that Fei Qian is a madman.

For example, the Western Regions.

The problems in the Western Regions broke out too quickly, too early, and too chaotic.

Fei Qian had previously sighed with Pang Tong that if the problems in the Western Regions could be delayed for a few years, the problem might be relatively simple.

After all, Lu Bu is old.

The midlife crisis is not only present in later generations.

Capitalists in later generations have to coax young people in various ways, but as long as they reach 35, wouldn’t they just squeeze them out? The decline in physical functions, the education and support of the next generation of the family, and the assets and liabilities, etc., can make an ambitious young man a screw that is willing to be ordinary.

At that time, even if Lu Bu wanted to make trouble, he wouldn't be able to make trouble.

Should his child go to Chang'an Academy?

Do he want to have a small courtyard in Chang'an?

Should he leave a place in the martial arts hall?

Sometimes Fei Qian feels that he is gradually becoming cold. When encountering anything, he subconsciously uses benefits to directly measure it rather than emotions.

[The novel app that has been running stably for many years is comparable to the old version of the book-chasing artifact, and the source change app that old bookworms are using, huanyuanapp.org]

The larger the territory, the less Fei Qian can use emotions as a bargaining weight to measure right or wrong.

It's right to the thing, not the person.

This principle is simple to say, but not easy to do.

Selfishness is the most important aspect of human animal nature, but the higher the position, the less selfish you are. Lu Bu obviously did not control his selfishness. He wanted to get more, but in fact he was constantly losing. He wanted to gain freedom, but actually lost his freedom.

Just like if Lu Bu is told the words "righteous to things, not people", Lu Bu will probably smile and say, "What's the matter?" How can he not know? But when he is dealing with the problem, is it targeting things or because of people?"

Most of the problems in the Western Regions were accomplished by people before, but now what Fei Qian wants is to become a person because of things.

This is a new battlefield, a new concept.

Lu Bu is already old, not only in his body, but also in his mind.

There are still ways to do physically, but it is difficult to change the mind.

After all, someone said that it is easy to treat a person's body, but it is difficult to treat a person's mind.

A person's talents are different.

Just like Fei Qian is fighting against the Five Slags, Xu Chu may only need one arm to knock Fei Qian down.

But the question is, how many Xu Chu are there in this world and how many Lu Bu are there?

So, if you just wait for a powerful person to appear before you can make any changes, then is it impossible to explore the Western Regions except for people like Zhang Qian and Ban Chao? Can you only have the ability to defeat the nomads like Wei Qing and Huo Qubing?

These people who are full of courage and wisdom should become role models, not confinements.

Inherit courage from the brave and wisdom from the wise.

What Fei Qian wanted was that ordinary Han people could also solve problems step by step based on relevant examples and laws passed down by their ancestors, so as to open up the territory of the Han Dynasty, and insert the Han Dynasty's flag into every piece of land in the world!

And Lu Bu, the courage used the wrong place, and the wisdom also thought the wrong place...

Some smoke and dust rose in the distance, and the sound of horse hooves came.
