Chapter 640

"Ah Chai, you've asked a little bit." Ye Qingxin looked at him approvingly.

This is something she has been paying attention to, originally wanted to "build a high wall and accumulate grain", who knew that she would enter a wartime state all of a sudden, and it would take at least a month or two to burn bricks and build a wall, but now I am afraid it will be too late, so I have to find another way.

Being praised by the goddess, A Chai showed a proud smile on his face, and he deliberately glanced at Ah Du and said, "Goddess, what should I do with the fence?" ”

Adu snorted softly, showing disdain.

"It's very simple, in order to defend against sneak attacks, the fence should be encrypted, and the defense function should be increased."

Ye Qingxin casually broke a few branches, used a small copper knife to cut the branches into different sharp shapes, and handed them to Qi, "Look at these sharpened branches, what do you think?" ”

Qi held the branch and frowned slightly, "Piercing people? ”

"Yes, sharpen the wooden poles, divide them into three or more layers, and insert them under the fence, not only to seal the empty fence, but also to protect against invading enemies."

Ye Qingxin drew three lines on the ground with branches as a fence, and then inserted the first layer of short sharp branches in a dense row, "This is the first layer to prevent wild beasts from invading." ”

Then, she cut a few longer branches, spaced them next to the short branches, "This is the second layer, not only to prevent wild beasts, but also to prevent enemies from sneaking in." ”

Finally, she thrust into the third layer of higher pointed branches, "This is the third layer, as tall as a person, to prevent enemies from jumping in or throwing stones. ”

Qi nodded slightly, and immediately asked a question, "What if someone else secretly lights a fire in the fence?" ”

"Good question, proof you're thinking." Ye Qingxin reached out and touched Qi's head, and said in the tone that he usually teaches students:

"I've also thought about this, first of all, to make fence wood, you must use thick trees, so it won't be easily ignited.

Secondly, we have clay pots in our tribe, and at intervals under the fence, we prevent a clay pot filled with water, and if you find a fire, you can put it out with water at any time. ”

With that, she was surprised and surprised to see the surprised and strange looks of several other people.

"What's wrong? This approach...... Isn't it good? Ye Qingxin asked in confusion.

"Good! Absolutely! Ah Du's eyes turned around and looked at Ye Qingxin's hand.

Ye Qingxin remembered that Ah Ge once told her that she couldn't touch other people's heads casually in the tribe, and touching her head was like rubbing a male with her body, indicating that she wanted to have fun with him.

And what about her...... touched Qi's head in front of the public, isn't he in love with him?

At this time, Qi had already grabbed Ye Qingxin's hand, grabbed the lips and kissed her lightly without hesitation, took her into his arms, and said with a faint smile:

"Don't worry, let's go back to the cabin ...... after talking about things."

I'm anxious for you big head ghost, my mother doesn't mean that!

Ye Qingxin's cheeks burned hot, and he stood up from Qi's lap in a sneer, cleared his throat and said:

"What do you think, get down to business! Kai, do you think this method will work? ”

A doting smile appeared on Qi's lips, and he said in a deep voice, "I think it's good to prevent someone from our tribe from sneaking out, meeting with the people of the Mengye tribe, and preventing the attack of beasts and enemies." ”

Ah Du and the others also nodded in confirmation, looking at the intimate small movements between the leader and the goddess, their faces were still a little sneering.

After all, it's not good to disturb the pleasure of the goddess of Qihe.

Seeing that those guys suddenly became silent, Ye Qingxin's face was full of black lines.

It's really cheap, and now she can't wash it when she jumps into the Yellow River.

"You ...... No more questions? ”

There was a touch of embarrassment in the atmosphere, and Ye Qingxin asked helplessly: "For example, the thickness of the wooden pole, how to layer it or something......"

"No, no, it's good that you can decide, goddess." Ah Du laughed "ill-intentionedly", got up and said, "Kai, goddess, I'll go back to the wooden house to see if the baby is breastfeeding." ”

After that, the soles of his feet were as if they were oiled, and he slipped away.
