The war drums on the warship are used to send orders, and there are several disadvantages.

If it is against the wind, the drum sound will be blown to the side by the wind, and the drum sound standing in the wind can reach Lao Jiu at the tail of the wind. If you stand at the tail of the wind, you want to spread the drum sound to the boat that is in the wind, it will not be able to reach it.

When the waves are calm, if the warship chases the enemy and is far away from the master ship, the master ship wants to send orders to the warship and let them come back, but it will not be transmitted. If a tiger is pulled out of the mountain at this time, then the rear will be eaten.

If there are shortcomings in the distance, it will not work even when it is close. The main general ship sends orders. When other ships want to give back to the main general ship, they also respond with drum sounds. Or if they discover new battle situations, report the situation to the main general ship, or have something to tell other ships, they all use drum sounds. When the battle starts, there will be more information to be transmitted, and all drums are ringing. How can we tell which drum sounds were made by which person? This is impossible, and it will be chaotic. If the battle between the enemy and us starts to fight together and the enemy and our drum sounds also starts, it will be even worse. Where can we know which drum sound is transmitted to them?

General Yan talked to Li Chengqian about these shortcomings while walking.

As the bottom-level chief general of the navy, he had long had a deep understanding of these issues, but over the years, everyone has been thinking about how to make the navy fight in an orderly manner, but never thought about how to find new ways to change it.

Li Chengqian's statement made General Yan feel some hope, but he didn't understand the essence of these casual words, so he asked Li Chengqian to come over to his side to drink and discuss it together.

This is also free, so it’s better to go back in more than ten days.

So Li Chengqian agreed.

In the evening, General Yan arranged the food and drinks, and Li Chengqian took Lao Long, Monk Zhu, and Cheng Wenxiao, the little hostess.

As soon as he sat on the table, Li Chengqian took out a few flags he had to cut out, and then talked to General Yan at the table. The Chief Cao who brought Li Chengqian over was also here, but he did not take the seat and poured wine beside him. But it can be seen that he was called to come to see the flag order. It seems that the Chief Cao who was guarding the shipyard was General Yan's confidant.

While drinking, he taught the flag order. Several people were recording something next to him. At the end of the drink, Li Chengqian didn't know what he said. Anyway, he woke up in the morning and felt dizzy.

Then he found that General Yan was gone. When he found him, several flags were inserted on his back, red, green and yellow. This was to be a traffic light!

On the playground, there were also many soldiers waving in the distance with flags.

It seems that they listened to their words, and then wanted to experiment with the flag order and formulate their own set.

As long as you know a creative idea and customize a fixed gesture, it’s fine.

In three days, General Yan and his team converted their original drum commands into flag verbs. Then they gathered and went out to train for the results.

Li Chengqian got on the boat again. Isn’t there no drum sound this time? So don’t you have to worry about your ears being abused.

If it weren't processed, Wenxiao would be a little bit abused.

Lao Long and the others knew that they would vomit when they got on the boat, but Li Chengqian was responsible for their safety, so it was natural to follow him.

But Cheng Wenxiao didn't use it, but she still came, which was really a bit abused.

Before Li Chengqian got on the boat, he told her to cut it with lemon slices and stick it to the navel, which would be better.

After leaving the sea, General Yan and his team began to experiment with flag orders. Because of the experiments in the previous three days, the messengers were familiar with the flag orders, and the reaction they made was very smooth.

In short, this flag order has been initially practiced and has been successful.

But there are still some problems. Are there some commands for the flag order? There are too many actions and difficult to express. There are also more simple commands that are not universal or simple.

Li Chengqian decided to work with them to improve the flag order, and of course, the lamp order, for use at night.

But after just a long time of research, Li Chengqian heard news from the navy that five large ships had entered the inland river in the downstream.

Five ships still entered the inland river, so where did this ship come from?

He suddenly thought of the sea boats, and the ships that went to Europe were back.

He was delighted and stopped staying here anymore. He wanted to go back to Chang'an to see how the situation was!

So he threw the matter of the flag order to General Yan to do it himself and went back to Chang'an by himself.

I was still reluctant to part with Cheng Wenxiao. I walked slowly from Donglai to Qizhou. After walking for half a month, I sent Cheng Wenxiao to my home. Only then did Li Chengqian and the others quickly go to Chang'an.

Originally, the boat must be slower than the horse, but I heard that it was already a month ago that the big boat entered the inland river. So the boat should have arrived early and the things were delivered to Chang'an.

This is the first time sailing, and Li Chengqian is looking forward to something he will bring.

It took ten days less than the last time I came here, and Li Chengqian and the others finally arrived in Chang'an. It was so dusty all the way.

Stayed in the city closest to Chang'an for one night, washed my face, and then entered the city with a glorious look and returned to Furong Garden.

Although they lived last night, they were still made like bandits by the dust and sand along the way, which scared the group of people in Furong Garden, and then recognized Li Chengqian and everyone became happy.

It’s midsummer to go out, and it’s late autumn to come back.

When you arrive in Chang'an, there is no need to hurry. Let someone go to each company to report a letter and come back by yourself.

The royal palace, the Cheng family, the Wang family, and the subordinates of Yu Zhining, Zhu Fatty, and of course the mistress Gui'e.

Report a letter first, and then go to everyone who needs to come to your door in person, and then go and have a look.

I originally wanted to see the queen again tomorrow, but after hearing the news, the queen came to Furong Garden first.

When she entered the door, she saw Li Chengqian holding his son. Xiao Lixiang was looking at the stranger with a sloppy face and cried loudly, but the crying did not call for the rescue of her dear mother, nor did she get the help of the two kissed aunts. Instead, they laughed endlessly there, and the strange bandit was also smiling happily. It would be better for this grandma. After coming in, she rescued herself, then patted the bandits, and finally kept the bandits away from her.

The bandits are terrible!

Thanks grandma!

"My mother, if this child doesn't kiss me, why are you going to beat me?" Li Chengqian said aggrievedly.

The queen said angrily: "You don't shaved when you come back. Look at her face, it looks like a hairy person, and you have the nerve to say..."
