"Jianguo, is this thing really that powerful?" Ma Guoliang asked.

Xu Jianguo nodded and said, "Yes, and this is not the most powerful one. However, considering the casting weight and equipment weight, this current design is the most suitable."

"According to what you said, won't all our wooden handles be eliminated?" Ma Guoliang continued to ask.

"That's not necessary. The two types of grenades I designed can be considered to be equipped only to small elite troops in the early stage, so that they can complete some behind-enemy-line reconnaissance, infiltration or decapitation operations, which can effectively improve the success rate of the mission." Xu Jianguo said.

"Is it the special forces you mentioned?" Ma Guoliang asked.

"Yes!"

"It seems that I should change my thinking. If your equipment is produced by then, but there is no one in our base who can match it, it will be a huge embarrassment!" Ma Guoliang said.

Xu Jianguo didn't say anything, but just smiled and gave him a thumbs up.

Ma Guoliang rolled his eyes at him and said, "Pack up and take my car back. You've been working hard these past few days. Go home early today to spend time with your wife!"

"Okay, thank you, Commander!" Xu Jianguo said with a smile, then rolled up the drawings on the table, wrapped them in a layer of canvas, and stuffed them into a waterproof storage bucket he made of iron sheets.

After locking the door of the small workshop, the three of them walked towards the front yard of the office building. On the way, many people took the initiative to greet them, which made Xu Jianguo look confused.

"Commander, what's going on?" Xu Jianguo asked.

"It's okay. I have cleared all the obstacles ahead for you. Now it's up to you. By the way, please submit the materials you need as soon as possible. I will apply for them for you as soon as possible to avoid wasting time on the road." Ma Guoliang said.

"Okay, I'll send you the list of materials tomorrow!" Xu Jianguo said with a smile.

At around four o'clock in the afternoon, Xu Jianguo returned to his home. As soon as he opened the gate, he found Daya squatting in front of the hole in the fire wall, shoveling coal into it with a small shovel.

Hearing the voice, Daya turned around and saw that it was her brother. A smile immediately appeared on her face and she shouted, "Brother, you're back?"

Xu Jianguo walked over to her, squatted down, rubbed her head, and said with a smile: "Our eldest daughter has grown up and can help with housework! Here, this is a reward from your brother!"

After Xu Jianguo finished speaking, he took out a pink hairpin with a bow on it from his pocket.

When Daya saw it, her eyes lit up immediately. She smiled and said to Xu Jianguo, "Thank you, brother!"

Then she took the hairpin from Xu Jianguo's hand, looked at it over and over again, and couldn't let it go.

When Wen Sitian brought Daya back into the house, she was teaching Erya and Funniu how to write.

When the two girls saw Xu Jianguo coming back, they immediately put the pens in their hands on the table, ran to his side, and each hugged one of his thighs.

"Brother, you're back?" Funiu asked.

Xu Jianguo looked down at the two of them with a smile, rubbed their little heads, and just as he was about to speak, he heard Wen Sitian's voice: "Come here, both of you. It's useless even if your brother comes back. If anyone doesn't finish writing, they won't be able to drink Le Duoduo tonight!"

When Erya and Funiu heard this, they curled their lips and looked at Xu Jianguo with their big eyes for help.

But Xu Jianguo spread his hands and said helplessly: "Don't look at me, it's useless. Your sister-in-law has the final say in our family!"

When the two girls saw that there was no hope of getting help, they immediately let go of Xu Jianguo's thighs and ran back to write obediently.

Seeing the two of them start to write properly, Wen Sitian turned to look at Xu Jianguo and winked at him. The couple smiled at each other, and everything was said without words.

Since it was still early, Xu Jianguo simply sat down at the table, took out manuscript paper and pen, and started writing.

Wen Sitian was curious and asked, "Jianguo, what are you writing?"

Xu Jianguo looked up and smiled at her, and told her about Ma Guoliang finding the descendants of Li Dashan's comrade-in-arms.

After hearing this, Wen Sitian was also very happy. Counting the time, it has been almost a year since she left Sandaliang Village. It is indeed time to write a letter back.

So she also picked up a stack of manuscript paper and began to write a letter to her good friend at the Red Star Machinery Factory.

In this way, the five members of the family gathered around a table and started writing. No one spoke in the room, only the sound of pen tips rubbing against paper.

An hour later, Xu Jianguo folded the letter paper, and Wen Sitian went to the cabinet to get the envelope, glue and stamps. The couple sealed the letter together, then wrote the address on the envelope and put a stamp on it.

Xu Jianguo wrote several letters in a row, some to Li Dashan, some to Li Mancang and Li Erniu, and some to Yan Wenhua and Gao Wangshan.

These are all people who have helped him before, and Li Mancang and Li Erniu are like his own relatives.

Xu Jianguo included a letter written by his comrade's descendants in the letter to Li Dashan, and a few photos taken during the Chinese New Year last year in the letter to Li Mancang and Li Erniu. In addition, he also put some national food coupons and twenty yuan.

Xu Jianguo didn't know how the grain harvest in Sandaliang Village was after he left, but his roots were in Sandaliang, so he didn't mind making life better for those around him who had done him favors when he was able to.

During dinner, Wen Sitian suddenly suggested eating hotpot. Xu Jianguo's eyes lit up when he heard it. It was rare for his wife to suggest something, so he had to satisfy her.
