The halberd is a combination of Ge and the spear, that is, a spear tip is installed on Ge's head.

A fighting weapon with the dual functions of hooking and stabbing, and its lethality is stronger than that of a go and a spear.

The halberd is very long, and the standard halberd of most countries must be more than two and a half meters, which is also a characteristic of battlefield weapons, one inch long and one inch strong.

Halberd in the Spring and Autumn period is mostly used on chariots, mainly used for direct stabbing and horizontal strikes, when the chariot rushes into the enemy's infantry phalanx, the halberd will become a handle to harvest life of the death sickle, as long as the armor pierced, it can take away the enemy's life.

The infantry will also be equipped with halberds, but the infantry is more equipped with spears, and halberds are a relatively luxurious weapon for infantry.

Perhaps due to the metallic nature of bronzes, knives were rarely used in this era.

It's not nothing, it's just that the bronze knife is too brittle, and it can only be used to chop a few times, and if it doesn't hit the enemy's vital point, it will break directly from it, which is almost equivalent to a disposable weapon, which is equivalent to giving it for nothing.

Therefore, the standard equipment of most countries is to use halberds, spears or long swords to carry out direct stab attacks.

Moreover, compared to the metal bronze used in bronze knives, the halberd and spear head of the halberd spear consume a little less, and the halberd shaft and gun shaft can be directly made of wood.

After finishing the halberd, Sun Wuyou took out a wooden crossbow from the room.

The crossbow is very new, and it seems to have just been made.

Legend has it that the earliest crossbow was invented by the Yellow Emperor, and the crossbow of the Spring and Autumn period was an extremely common strategic weapon, which Sun Wu also mentioned in his "Art of War".

The crossbow of the Spring and Autumn period could fire about 400 paces, and compared to the bow, it was easier to use, it did not require much training to go to the battlefield, it could effectively restrain the infantry, and it had a huge morale blow to the enemy's phalanx.

Especially the two-stage shot and the three-stage shot.

Unlike bows and arrows, crossbows do not require too much effort to pull the bow and open the strings, and ordinary soldiers can basically be considered great if they pull the bow more than ten times, while crossbows can be wound fifty times in a row, or even more.

The second and third shots can make the crossbowmen's attacks have a continuous effect, and the arrows fall like a storm, and the scene is extremely shocking.

The rest is the category of shield swords, which generally belong to the guards of the generals, and their physical strength, explosive power, and combat skills all belong to the top "special soldiers".

After learning about the types of troops and the mainstream standard weapons, Sun Wu officially began to teach the art of war.

It is worth mentioning that he still did not directly start talking about how to fight.

"Soldiers are the great affairs of the country, the place of death and life, and the way of survival, which must not be overlooked. Therefore, the scriptures are based on five things, and the school is based on calculations to find out their feelings: one is the Tao, the second is the sky, the third is the earth, the fourth is the general, and the fifth is the law. The Taoist makes the people agree with the superiors, so they can die with it, they can live with it, and they are not afraid of danger. ”

The "Tao" here refers to the truth, morality, or can also be interpreted as politics and public opinion.

As long as it is politically correct and the state is able to occupy the moral high ground, it can launch a public opinion attack on the enemy, so that its people and soldiers will have the will to share the same hatred and hatred of the enemy, and serve it to the death.

This is also known as the division is famous.

As long as people believe that they are righteous, then the morale of the battle will be unusually high.

The term "public opinion" here is subtle.

On the one hand, you can use righteousness to stir up people's emotions, such as the Japanese attack on Pearl Harbor, and the United States used this as an opportunity to officially start the military intervention in World War II.

On the other hand, you can also use benefits to induce the people and stimulate people's enthusiasm for fighting. For example, the US-led Gulf War was an "unjust" war for oil resources.

But...... Is the so-called "unjust" war really "unjust"?

"So how is righteousness and injustice defined?" Ouyang pondered for a long time and asked, "Is it according to the world's point of view? Can a war that is beneficial to the people of one's own country but hurts others be regarded as 'righteousness'?"

"That's not what I'm thinking about. Sun Wu smiled, looked at Li Er who came over and said, "The virtue of people, the virtue of the country, the virtue of heaven and earth, about these things, you have to ask 'Lao Tzu'." ”

Li Er entered Sun Wu's small courtyard, heard the conversation between the two, and asked a little strangely, "Oh, Ouyang, are you interested in Dedao?"

"Hmm...... A little interested. Ouyang nodded.

"If you're interested, you can discuss it sometime. Li Er smiled, looking very happy, "But it's not right now, Changsangjun is back, he has something to do with you, it's about Shennongsan." And I happened to be looking for Sun Wu to have some things. ”

Could it be that there are some problems with Shennongsan's dispensing? Probably not, otherwise Li Er's expression would not be so happy.

"Well, then I'll quit first. Ouyang saluted Sun Wu and left the courtyard.

Sun Wu watched Ouyang enter Changsangjun's small courtyard and looked at Li Er: "Say, what are you doing with me, for Fan Li?

"Of course not. The young uncle and the two of them are about to leave Shennongjian and change places to live in seclusion. Li Er smiled and took out a tattered turtle shell from his bosom.

The turtle's shell was covered with knife marks, which seemed to have been artificially cut, and there were many scorched places, as if they had been burned.

"This is...... Xuanwu?Did you divination?" Sun Wu showed a shocked expression and looked at Li Er, "Are you crazy?!How many Yang Shou do you still have?"

"Death is the only way to live. Li Er waved his hand, indicating that he didn't care.

"Hush. Sun Wu pursed his lips, put away the halberd and crossbow, and asked, "So what? What did you see this time?"

Li Er tapped the turtle shell with his fingers, then pointed to the top of his head and said, "The hope of life comes from outside the sky. ”

Sun Wu followed his fingers and saw a cloudless blue sky.

....................................

Chang Sangjun had good luck going out this time, and with the materials brought by Fan Li, he completed a total of two copies of Shennongsan.

One was given to Shi Yiguang, that is, Xi Shi, and the other was given to Ouyang.

After curing Xi Shi's angina pectoris with acupuncture, Fan Li did not stay in Shennongjian anymore, and took Xi Shi to live in seclusion without knowing where to go.

Shennong San is really a packet of powdered powder, soaked in cold "distilled water", and then drunk directly.

When Ouyang saw the "distillation bottle" in Changsangjun's house, he almost thought that Changsangjun was also the one who crossed over.

"After taking Shennongsan, take the first rays of sunlight to the morning dew every morning, and insist on it for thirty days, and you can completely digest Shennongsan. Chang Sangjun explained for Ouyang.

After Ouyang drank Shennongsan, he closed his eyes and felt it, and found that he had not changed at all, but in a hazy way, he seemed to feel something.

But it is too vague, and this hazy feeling is equal to nothing, as if it is just a psychological effect.

"Thirty days later, you will be able to know the mystery of immortality?" Ouyang couldn't help but ask.

This is immortality, although it is only eighty years, but this represents the most important first step taken by Ouyang.

"Hmm, look at people, right?" Chang Sangjun said uncertainly, "Some people can naturally know, and some people ...... For various reasons, some prerequisites are missing, that is, the mystery of immortality cannot be seen. ”

"What do you mean?" Ouyang scratched his head, "Some people are destined not to live forever?"

"That's not what I say. Immortality is just a concept, to put it bluntly, it is to lift the shackles, and then to live so many years of yang life. But some people are born without shackles, as long as they do not take the initiative to die, they generally will not die early.

There are also some people who need some specific environment to stimulate in order to see their shackles, so as to know how to break them and gain immortality. But these particular environments are too random. Chang Sangjun explained.

"I see. Ouyang nodded, then put down the burden on his body and said, "This is my clothes, and now it's yours." ”

During Fan Li's three days in Shennongjian, Ouyang asked him for two clothes, and then changed them slightly with a tactical dagger.

If you don't change it, you can't do it, on such a hot day, you still wear so thick, it's really easy to get heat stroke.

Chang Sangjun nodded and put away his burden.

When Ouyang was about to say goodbye to Chang Sangjun, Chang Sangjun suddenly said, "Do you want to learn acupuncture and herbal medicine?"

"Huh?" Ouyang was stunned for three seconds, then nodded vigorously, "Learn!"

....................................

I don't know if it's because of the extremely high physical attribute panel, Ouyang's energy is very high, and his memory is amazing.

Studying Huang Lao's thoughts, Sun Tzu's Art of War, and Changsang's medical skills every day, he didn't feel tired at all, and even had a little spare strength to learn how to look at stones with Xue Candle.

Of course, Xiangshi just learned to play.

But if you don't learn, you don't know, and you'll be shocked when you learn.

If you look at the stone, you have to know where this stone is produced, right? What kind of reaction will this stone have when it is placed in a potion, what kind of reaction it will have when it is placed in fire, and what kind of reaction it will have when it is placed in water, you have to know all this, right?

You even need to know a certain amount of geographical knowledge, you need to know where the land is rich in what kind of stones, and where the weather will affect the stones, so this includes bits and pieces such as meteorology.

So Xue Zhu is the most knowledgeable person in the entire Shennongjian Ouyang couldn't help but have such a strange thought.

In addition, chopping wood, farming, fishing, herding sheep, and learning with Zhao Zhen, these bits and pieces of daily life work are all in the daily plan.

This amazing workload and learning efficiency amazed the old people in Shennongjian, and even had a strange thought of "am I really old".

After all, even Zhao Zhen, who had already entered the realm of the unity of heaven and man, could not learn so much knowledge in one breath like Ouyang.

Our "Yue Nu" is better at figuring out how to cut people and let her use her brains or something, which is indeed a little difficult for her.

Of course, in fact, it is not that Ouyang has a strong learning ability.

In fact, in this era where there is no Internet and no electronic products, learning and learning have become the only entertainment.

Otherwise, can you still do it in such an isolated place, in a daze every day?

In that case, you're going to die.
