Hurriedly filling his stomach, Wu thanked the firehead soldiers for their kindness, returned to his residence, and checked the things he had written before one by one to make sure that there were no mistakes, and then began to sort them out in order.

After finishing the arrangement, Wu Yong used tools to bind these pages into a book, so as not to lose them when he got them.

After taking Xiao Hei and Songguo out to let them out to let off steam, Wu Yong continued to bury his head in writing tutorials, and was busy until the evening, before he completely stopped, these things were enough for them to learn for a month, and then they could write some every day.

After making these things written in the afternoon into a booklet, Wu Yongcai walked out of his tent, and happened to meet Gongsun Sheng, who had just come out of the laboratory, and the two went to dinner together.

The two of them also had a kind of fatigue after being busy, and they no longer cared about the health rules that they should eat less at night, so they filled their respective plates to the brim and found a sheltered corner to eat slowly.

After having fifty percent of the food in their stomachs, the two of them slowed down their meals, and asked each other about the recent results.

Wu Yong said about the flag: "What do you think? I originally wanted you to help me get some other means of communication, but after thinking about the time it would take, I gave up, or it is more convenient to have a ready-made thing like the flag." ”

Gongsun Sheng nodded approvingly: "That's true, but I can also help with other communication tools, but it may take a long time to do so." ”

There are a lot of technical challenges to overcome, and it takes a lot of time and effort.

As for Gongsun Sheng, he also explained what he has been busy with recently: "General Huang asked me to help improve the tools for defending the city, so I have been working on this kind of thing in retreat recently, and today it happened to be a little progressive, so I ended up early and went out for dinner." ”

Wu Yong has always been more measured in this regard, and he didn't ask Gongsun Sheng what progress he had, and directly sent encouragement: "That's good, I hope you can complete it as soon as possible." ”

Gongsun Sheng nodded: "I think so too, I hope to complete the improvement and test before the war, and I can help when the time comes." ”

When the two of them were about to finish eating, they saw Gao Yu and they also came over for dinner, so they beckoned them to come over to this location, they were about to leave, and they were also saved from finding another location, and now it is not easy to find a location at this time.

Gao Yu came over with the angel first, and they were still a little surprised that Wu Yong and them rarely came over for dinner so early: "Are you free today? Do you want to play together at night?"

Recently, the temperature has dropped a lot at night, and Gao Yu and they often eat some supper together around the fireplace at night, which is also a rare pastime, but in the past, Wu used them and they were not available, and this time they met and planned to invite them together.

Wu Yong and Gongsun Sheng thought about it for a while, then nodded and agreed, people still have to be gregarious, after asking the location, the two went back to their residence to wash up first, their current image is not very good.

The two changed into clean clothes and went to Gao Yu's house, where their meeting place this time was, and Gao Yu was already making preparations.

Seeing the two of them coming, Gao Yu asked them to sit casually first, and the others were about to come over, and they kept finishing the rest of the things.

Wu Yong and Gongsun Sheng wouldn't really just watch Gao Yu work alone, and the two of them handed Gao Yu things on the side, so that he wouldn't have to walk around, and it also improved his efficiency, so he could wait for others to come over together.

After everything was ready, Gao Yu patted Wu Yong's shoulder with satisfaction: "Thank you." "In the past, there were other people who arrived early, but they basically didn't help, and sure enough, acquaintances were more friendly.

Wu Yong and Gongsun Sheng didn't feel anything to thank for this kind of effort, and changed the topic to: "How long will it be before they come?"

As soon as their question was asked, they saw someone open the door of the tent and come in, so Gao Yu continued to greet the guests, poured tea for the three of them, and let them drink it slowly, after all, the others had not yet come, and they had to wait before they could eat.

Two quarters of an hour later, the others arrived, and Gao Yu's tent was full of people, and it seemed to be very lively, and everyone shared food together, and the atmosphere was very good.

They also took good care of Wu Yong and Gongsun Sheng, who participated for the first time, even if they didn't speak much, they tried to say topics they could understand, so as not to make them feel embarrassed.

Wu Yong felt that his stomach was already very full, so he stopped his chopsticks and began to listen to other people's chat topics, which was quite interesting, basically some of the customs and customs here, as well as the things he had recently taught, they would also take them out and ask Wu Yong.

This party lasted until late at night, and one after another people left to rest, Wu Yong and Gongsun Sheng stayed behind to help Gao Yu clean up.

After cleaning up the mess here, Wu Yong and the others also planned to leave, and before leaving, Gao Yu mentioned one thing: "My people have found out the news, Master Tong is about to arrive here, tomorrow night at the latest, can you spare time to go to the city gate on the other side with me tomorrow and wait?"

It's not easy to find an angel to do this, so Gao Yu can only discuss it with Wu Yong.

Wu Yong thought about it for a while, nodded and said, "Okay, tomorrow except for one hour in the morning, I am free, and I can go with you then." ”

Although tomorrow is the first day of training, Wu Yong is not too worried, as long as he follows the process, the main force of learning is still those who want to learn the flag language.

After the two agreed on tomorrow's affairs, Wu Yong and Gongsun Sheng left the tent on Gao Yu's side together.

After leaving the tent, Gongsun Shengcai said, "How about I come to the class tomorrow?"

Wu Yong was a little surprised: "Can you find time?"

Gongsun Sheng: "I still have an hour's time." ”

Since he had a heart, Wu Yong would not refuse him to come, and the two went separately to rest after that.

The next morning, after the morning training was over, Wu Yong took the tutorial to be used today and went to the tent that Huang An specially packed out to prepare for today's class.

This tent is different from the previous single tents, the space inside is vast, and many people can sit, Wu fixed the blackboard on the wall of the tent, and began to write the knowledge points to be taught today, while also waiting for other students to come.

The first to come over was Gongsun Sheng, who walked up behind Wu Yong and asked, "Is there anything you need my help with?"

Wu wiped his hands with a damp cloth: "No, why did you come here so quickly?"

Gongsun Sheng still helped Wu Yong send the tutorial down: "I came directly after breakfast, and the others probably have to sort it out." "And they finished training earlier than they did.
