The half piece of wood used for the lintel is very wide and thick, and the wider part is inside the wooden frame. In this way, the height between the top and the bottom is reduced by at least five centimeters compared to the outside of the door frame.

It is also because of this that the door, which was originally placed loosely outside the door frame, became stuck after being moved inside the door frame and placed close to the door frame. Even if it was let go, the door would not tilt too much to one side like before.

Lame's eyes lit up and he felt as if he had found the right direction.

In joy, he pulled the door with his hands and began to try to open and close it. The wooden stick that protruded from one side of the door was stuck between the lintel and the ground. As he pulled, the door began to rotate around the stick.

The door was opened, and Lame's eyes became brighter. By now, he was sure that his approach was correct.

He tried opening and closing the door again and again, and gradually his brows began to frown again.

This way the door can indeed be opened and closed, but it is very unstable. If you are not careful, it will tilt or run out of the lintel. Another thing is that it is very heavy to open and close, unlike the two large doors installed on the wall.

"Son of God."

Lame opened the door from the inside again, looked up and saw the Son of God standing not far from the door, holding a small basket full of rapeseed, looking at him with a smile, so he hurriedly greeted him.

"Very good, well done."

Han Cheng stopped a child from the tribe who was running by, handed her the basket of rapeseed, asked her to take it to the cave, and told her to tell the person in charge of cooking to put the rapeseed in the soup later.

After explaining all this, Han Cheng looked at the door carefully for a while, then looked Bo up and down, and praised him with a smile.

Lame was very happy to be praised, and then he pointed at the door and shook his head and said, "If it's not installed properly, it will fall down."

After saying this, he looked at Han Cheng expectantly, wanting to get a solution from the Son of God to overcome this difficulty and defeat the devil's malice.

Han Cheng thought about it for a moment, then went into the house with Bo and asked Bo to close the door again and straighten it.

Asking Lame to stay still, he used a broken tile he had just picked up to draw a semicircle on the ground along the door axis.

The door lintel was too high from the ground, and Han Cheng, who was not even as tall as Wu Dalang, naturally could not reach it. The task of drawing circles around the door axis had to be left to Bo.

Fortunately, the wooden door is not heavy, so I just need to use some force to push it against the door frame so that it won't move.

The lame man held the wall with one hand, tapping his foot slightly, and with the other hand held a tile and drew circles on the door hinge.

Although tiles are not as noticeable as red bricks, they can still leave traces if repeated several times.

After drawing the circle, Han Cheng asked Bo to move the door away from here and move it outside again.

Looking at the circle drawn on the lower part of the door lintel, Han Cheng suddenly put his hand on his forehead, feeling helpless.

After all the careful planning, one step was still missed.

When it was first built, I only thought of drilling holes on the lintel after the door was built, so that the position of the hole could be accurately determined to avoid blinding it.

It was not until this moment that he suddenly remembered that this was not the future, and with the current hole-drilling technology, it would be quite difficult to drill such a hole in mid-air.

Han Cheng looked at the door lintel that was completely integrated with the wall, and after some thought he gave up the idea of ​​taking it down and drilling a hole in it. Otherwise, this nice new house would become a dilapidated house before he could even move in.

Of course, another reason is that doing so is more troublesome than drilling holes in the air, and it will also seriously affect the firmness of the door frame, which is really not worth the loss.

When Bo Ban came back, he saw the Son of God looking up at the half circle he had drawn with a strange look on his face. He suddenly felt a little flustered, worried that he had not done something well and that was why the Son of God was like this.

Han Cheng withdrew his gaze from the circle above the door lintel and saw Bo's uneasiness. After a moment's thought, he realized that this guy had got the wrong idea, so he smiled and told him about drilling holes on it.

After hearing this, Lame felt less anxious. After thinking for a while, he said that he would definitely find a way to get the hole out, and he pounded his chest as a guarantee.

After saying this, Bo immediately brought over a large lump of mud and started a large fire not far from the door.

He moved two stones over to serve as stepping stones, then spread mud on the door lintel, covering a large area and leaving only the circle.

Then he took out a burning stick from the burning fire and put it close to the round hole to burn it.

He held a stick of firewood in one hand and a bone blowpipe in the other to blow air to light the fire. When the fire on the stick went out, he would bring the top part with the charcoal close and continue blowing.

However, this is indeed too troublesome. Not only is the posture uncomfortable, but the charcoal can easily go out or fall.

It would be great if there were metal tongs at this time so that we could directly pick up the burnt charcoal instead of having to do it with such difficulty as it is now.

Han Cheng, who was watching Lame from the side, nodded slightly. The method used by Lame was the same as what he thought. It seemed that the first carpenter of the Qingque tribe had been trained by himself.

If the Qingque tribe could continue to exist, Bo would have become a person like Lu Ban, right?

Well, it should be passed down. After all, Wu and his disciple Shitou have been recording things on the pottery board tirelessly.

Lameness will definitely be recorded.

What about yourself?

Han Cheng suddenly thought of this question. If the Qingque tribe became strong enough and its influence became more and more far-reaching in the future, he would probably become a god like Gonggong and Zhurong in ancient mythology, or even become an existence like Huangdi and Yandi.

Han Cheng was thinking about this, and his face suddenly twitched, because he suddenly remembered the witch's record of his origins, lightning and thunder, falling from the sky...

It is estimated that it is more likely that they were regarded as aliens by later generations and the early Qingque tribal civilization was classified as an alien civilization.

Thinking of this, Han Cheng was looking forward to the day when someone would dig out all of this dusty information after who knows how many years.

I’m sure those archaeological experts will be shocked when the time comes. It’s interesting to think about it.

"Son of God."

A sound woke Han Cheng from his unrealistic fantasy. When he looked up, it was the wood he had asked someone to bring back from the quarry.

Han Cheng took the wood and found a relatively straight stone that was about fifteen, eleven and eighteen centimeters long, wide and high respectively.

He asked Bo, who was standing on the stone with his arms raised and his head tilted back, burning the mortise and was sweating profusely, to stop and rest. He and Mu Tou moved the big stone to the place where the circle had just been drawn. After adjusting the posture a few times, he used a short ruler to draw a cross on the relatively flat surface of the stone, and then drew a circle with the cross as the center, which was slightly larger than the circle on the ground.
