Jing Hailin thought for a while and said, "The next gun to be designed should ensure that its shooting accuracy is good, the action is reliable, the weight is light, the gun body is short, the structure is simple and compact, the gun is easy to operate, easy to carry, good mobility, strong firepower, long life, a gun is multi-purpose, and most parts such as drums and magazines can be interchangeable and common between the guns of the gun family." ”

"That's right! The magazine is not compatible with the biggest annoyances, and captured bullets cannot be used. Hong Xueli frowned lightly and said, "We must improve." ”

"Then I'll leave this to you." Jing Hailin said directly.

"No problem." Hong Xueli said very simply.

Then the couple had a lively discussion, drawing on the beach with a pen of reference.

The pictures are so vivid that they are often drawn, even on the beach, they can be drawn exactly right.

It can be regarded as letting Ding Haixing know what the two of them are like at work, and they are selfless and devoted.

From the basic principles of machinery to process design, from materials to technology, from production to lathe transformation, the two discussed one by one, and did not let go of any small nodes.

Speaking with a dry mouth, General Ding Haixing handed the kettle to Hong Xueli and said, "Sister-in-law." ”

"Thank you!" Hong Xueli took the military kettle, unscrewed the lid, and poured two sips of goo dong and goo dong, "Give." He handed the kettle to Jing Hailin.

Jing Hailin drank half a pot of water in one go, "It's really enjoyable." Pushed Hong Xueli and said, "Do you still drink?" ”

"I don't drink anymore." Hong Xueli shook her head slightly.

Jing Hailin screwed the lid on, put the kettle on his shoulder, raised his eyes to look at Ding Haixing and said, "It's boring to listen to us!" ”

"No, what you say is easy to understand, I can understand it." Ding Haixing looked at them with clear eyes like spring water, and said seriously, "It's still very humorous." ”

"Hehe......" Jing Hailin smiled softly when he heard this, "This is all the credit of the old war, I wanted to give a lecture to the soldiers back then, he said that it should be combined with reality, easy to understand, try to use less professional terms, and use more 'slang' of the soldiers." This habit was preserved. ”

Ding Haixing heard the words and a sweet smile appeared on the corner of her mouth, looking at them swimming happily in the sea, her smile became brighter and brighter.

&*&

The sun is shining, the sea is blue, and the seagulls are soaring in the sky, making loud chirps.

The sea breeze blows slightly, with a soft and lazy atmosphere, swinging layers of blue waves.

The sea flows quietly, and the children have fun in the sea.

Zhan Changsheng followed the children, and now he is really sure that the children can swim and swim well.

On the sparkling water, their bodies are agile, like shuttling fish, swimming around freely, tired of swimming, facing the sky on their backs, and letting the sea water push onto the beach.

What a lazy guy.

Ding Qihang saw his brother and sister swimming happily, his eyes were hot like something, and he ran into the sea with his little short legs, which frightened Ding Guoliang and Yun Lulu.

caught up with him in three or two steps, and hugged Ding Qihang.

"I'm going to be scared to death by you." Ding Guoliang said with trembling lips.

"Dad, I'm going to swim." Ding Qihang pointed at Cangming and said.

"Do you know how to swim, boy?" Yun Lulu walked up to their father and son, looked at him and asked.

"No, it won't." Ding Qihang's answer was simple.

"No, you dare to swim! I'm not afraid of being swept away by the sea! Yun Lulu reached out and gently wiped away the splashed sea water from his face.

"Does Daddy know how to swim?" Ding Qihang raised his head and looked at Ding Guoliang with big eyes.

"Of course I can swim, your dad and I can swim well!" Ding Guoliang said boastfully.

"That dad taught me." Ding Qihang looked at him expectantly.

"No problem." Ding Guoliang agreed coolly, looked at him and said, "Don't be afraid, choke, and don't cry!" ”

"I'm a man, so I won't cry!" Ding Qihang said angrily with a small face.

"Then let's get started!" Ding Guoliang let him down and pulled him towards the sea.

"You...... You watch your son carefully. Yun Lulu chased after her and said worriedly.

"Don't bear it, I'll follow him closely, not an inch." Ding Guoliang looked back at her and said.

Ding Guoliang walked over to the shoulder of the flooded little guy and began to teach him to swim.

In fact, it is somewhat difficult to learn to swim in the sea, after all, the waves are wave after wave, and it is not as calm as in the pool, without waves.

Yun Lulu looked at Ding Qihang's hard work and muttered, "I knew that I would teach him in the pool at the base, and it would be much safer there." ”

"We are too busy with work and don't have time, and my sister doesn't dare to bring so many children to the beach to play, even if they do, they don't dare to let them go into the water." Ding Guoliang said regretfully, "Next year!" Next summer, the church will set sail for swimming. ”

"Shhhh Don't bother me, be careful of drowning my son. Ding Guoliang bent over and said without raising his head.

Yun Lulu immediately stopped talking when she heard this, and the couple accompanied Ding Qihang to flutter in the water.

Ding Haixing looked at the family of three with a smile, raised her eyes to look at the sun, "It's almost time, you keep playing, I'll go home and cook." His eyes fell on Jing Hailin and his wife and said, "Now that Cangming's father is back, Teacher Jing and sister-in-law will stop cooking, let's be lively and lively together." ”

"Then I'll give you a hand." Hong Xueli immediately stood up and patted the sand on her buttocks.

Ding Haixing lowered his eyes and looked at Jing Hailin and said, "Teacher Jing, tell Cangming and his father later!" When you've had enough, go home. Then he handed him the cloth and said, "Here are the children's clothes, let them change when they come up." ”

Jing Hailin took the cloth bag and said, "I know." ”

Ding Haixing carried the basket and walked towards the base with Hong Xueli.

"Sister, you guys are going back!" Yun Lulu asked when she saw them raise her voice.

"Oh!" Ding Haixing turned to look at her and said, "Go home and cook." ”

"Wait for me!" Yun Lulu shouted loudly, her eyes fell on Ding Guoliang and said, "My son is handed over to you, I'll go back and help my sister cook." ”

"Go ahead!" Ding Guoliang said without raising his head.

"It's almost time to be back." Yun Lulu advised, "It's already autumn, and the cool air will come down in the evening." ”

"Got it." Ding Guoliang directly picked up his son and said, "Rest for a while, rest for a while, let's practice again." ”

"Hmm!" Ding Qihang lay on Ding Guoliang's shoulder and gasped, "I'm so tired from swimming!" I felt like my arms were sore. ”

"Hehe......" Ding Guoliang smiled and said, "Then let's rest for a while." ”

"Set sail, I'm leaving." Yun Lulu waved her hand and said to Ding Qihang.

Ding Qihang turned around and waved his hand, "Mother, goodbye, make more delicious food, I will definitely eat more today." ”

"Good!" Yun Lulu said happily, turned around and waded towards the beach after the words fell, and then strode after Ding Haixing and them.

The three of them returned home and worked for nearly two hours to make a sumptuous dinner.

As the sun sets, the tired birds return to their nests, "We're back." "Zhan Changsheng came back with a large army of Hula at once.
