"You think it's just a musical instrument?" Jin Yao looked at Fu Nian and asked.

"Isn't it?" Fu Nian regretted it after speaking, because all the musical instruments in the Central Plains didn't seem to be musical instruments at first.

For example, the five-stringed piano was originally a weapon on the battlefield, although he couldn't think of how the five-stringed instrument was used as a weapon, but almost all of the people who could use the lyre as a weapon on the rivers and lakes were first-class masters.

"You can still make the soldiers hear a musical instrument clearly on such a chaotic and noisy battlefield, and you still use it as a musical instrument!" Jin Yao shook his head vigorously, as early as before, he and Li Mu had made the revised version of the suona into a military horn, which had been used in the First World War.

"A trumpet instead of a war drum!" Fu Nian also reacted suddenly.

The military horns made by Li Mu and Jin Yao also composed eighteen kinds of orders, including morning cooking, drills, attacks, charges, etc., but there was no retreat.

"Why isn't there a call to retreat?" Fu Nian suddenly became curious.

"Because you don't need to!" Jin Yao said with a smile, in the face of the enemy, there is no need to have a retreating horn.

"Seriously!" Fu Nian did not agree with this answer, although the soldiers were brave, it did not mean that there was no need for a retreating military trumpet.

"It's very simple, on the battlefield, the situation is changing rapidly, the order to retreat must be notified by a special person, and the concealment is extremely high, it is impossible to convey the signal to retreat in front of the enemy, we can hear it, and the enemy can hear it.

If we sound the trumpet of retreat, it is difficult to guarantee that the enemy will not take the opportunity to counterattack, and the consequences will be unpredictable.

Therefore, on the battlefield, all the orders to retreat are done by heralds, and the time for retreat is set before the war begins, otherwise there will be another embarrassing situation like the previous disconnection from the army!" Jin Yao still explained to Fu Nian why there was no retreating military number.

At the beginning of the war, the pioneer battalion did not get the scheduled retreat time, so it would be alone and out of touch with the Chinese army, if it were not for Jin Yao always paying attention to the Quartet and withdrawing steadily, the situation at that time was actually very dangerous.

Fu Nian also understood that if the enemy retreated, he would pursue, and if he retreated, the enemy would also take this opportunity to counterattack.

"Lin Hu is finished, let's attack with the whole army, rush to Lin Hu's royal court within three days and occupy Lin Hu!" Jin Yao watched the situation on the battlefield change and gave the final battle order.

The trumpet sounded quickly, conveying a tune to the vanguard battalion, and the vanguard battalion that received the order withdrew from the battle one after another, no longer caring about the defeated Linhu soldiers, regrouped, and slowly marched in the direction of the Linhu royal court.

"Inner Sage and Outer King, the rest is up to your Confucians, we are only responsible for making the other party submit, as for how to make the other party naturalize, that is your Confucian specialty!" Jin Yao looked at Fu Nian and said, also trying to help Fu Nian improve his swordsmanship and avenue.

"Thank you!" Fu Nian also knew Jin Yao's thoughts, so he bowed gratefully.

Three days later, the pioneer camp appeared outside the royal court tribe of Linhu, only as the royal court of Linhu, but it still lived in pursuit of water and grass, and did not build a city and live in the same place like the Xiongnu and Donghu royal courts, and became a fixed place of governance.

It is precisely because of this that Li Mu will release part of the main force of the barbarians to lead the way for the army.

Seeing the sudden appearance of the army, the herdsmen of the Linhu royal court were excited, they had already been informed that the main army of the royal court had returned, so they were all waiting for the army to bring back endless food, women and children.

However, they were frightened, and when they heard the sound of horses' hooves coming from the ground, they thought it was their king's return, so they all gathered outside the king's court to greet them, but they didn't expect that it was not their king's master who was waiting.

"That's ...... The army of the Central Plains!" Looking at the white robe and red armor, the old man Lin Hu, who had invaded Yanmen Pass, recognized the origin of the pioneer camp, and his voice was full of trembling and fear.

For a while, the entire Lin Hu royal court was also in a mess, and they couldn't figure out why it was the army of the Central Plains that it was clear that there had already been a scout who had reported that their royal division had arrived outside the tribe for less than three days.

"Enemy attack, enemy attack, enemy attack!" Lin Hu's only remaining 5,000 royal court guards quickly raised the alarm and blocked the front of the tribal camp, trying to stop the attack of the vanguard camp.

"None of the men above the horseback will be left!" Jin Yao looked at the Lin Hu royal court that had appeared in front of him, looked at the yurt tent that received the blue sky, and ordered again.

"Whoa!" The soldiers of the vanguard battalion conveyed military orders one after another, and then went like a tide towards the Lin Hu royal court.

Fu Nian listened to Jin Yao's order and wanted to speak, but in the end he didn't stop him.

This is also the first time he knows the cruelty of war, all men above the horseback are killed, this is a bloody military order, and it will also make the entire forest and Hu bloody, but this is necessary.

"Only naturalized barbarians are entitled to live!" Jin Yao looked at the grassland coldly and said.

"This is the Outer King, the royal road soup!" Jin Yao said again, not only Confucianism has the royal road, but the Mo family also has it, but the royal road of the Mo family is closer to the soldiers, and it is more cruel and violent.

"Got it!" Fu Nian nodded, his royal way still lacked some domineering, but now he understands and has a deeper understanding.

The vanguard battalion will not show mercy, they are the sharpest presence in the army, and every head represents a military achievement, even if it is only an unarmed barbarian people.

However, as long as the man is taller than the horse, he will be their enemy, and there will be no more so-called killing and reckless merit under their military merits.

Therefore, the killing broke out in the royal court of Lin Hu, and it began, and the remaining royal court guards of Lin Hu were not able to stop the charge of the vanguard battalion at all, and they were quickly annihilated.

Jin Yao and Fu Nian also rode forward, and under the protection of the guards, they came to the treasury of the Lin Hu Palace, and the soldiers around saw Jin Yao and Fu Nian coming, and their subordinates suddenly paused, looking at Jin Yao and Fu Nian with anxiety.

"Take what you can take, and pack the rest back to Yanmen Pass!" Jin Yao smiled slightly, turning a blind eye to the soldiers' ransacking of Lin Hu's treasury and looting gold, silver and jade.

"Whoa!" The soldiers of the pioneer battalion were also relieved after receiving Jin Yao's words, and looted all the treasures that Lin Hu had accumulated over the years of plundering, but they only took away some of the treasures that they could hold, and the rest were also preserved and handed over to the prison army to escort back to Yanmen Pass.

"A soldier uses his life for a glory and wealth, and blindly strict military orders will only make the general lose his majesty, so sometimes, he should turn a blind eye and treat it as if he couldn't see it." Jin Yao said to Fu Nian.

"You're a natural general!" Fu Nian seriously commented that if he was also an ordinary soldier in the pioneer battalion, he would also use his life to serve such a general.

Therefore, Jin Yao did not stop the raiding of the pioneer battalion in Linhu and the female cadre Yin.

"Assemble the army in three days!" Jin Yao didn't care about anything else, and let the guard battalion join in.

In the past three days, the overseers will not take care of anything, and let the soldiers plunder.
