After a few back and forths, Goofy finally hammered the cylindrical steel bars into triangular columns, which were still not triangular thorns, but they were very close.

Next, Goofy began to hit the fine again, mainly to make the front fine, while also making sure that it was still a triangle.

Finally, after repeated beating back and forth, the triangular bar he needed was finally made.

Goofy took it in his hand and looked at it, still satisfied, he took the triangular column out of the kitchen, and searched back and forth on the hill around the outpost for a suitable sharp stone.

Gao Fei has already thought about the groove inside, that is, the groove to be opened on the three sides of the triangular long bridge column, so he doesn't need to beat it, and he can just grind it with a stone.

Gao Fei, who had an idea, quickly found a suitable stone, only to see him come to the sentry box, squat down against the side post of the sentry box, and then put the triangular column in his hand against the ground, and took the sharp stone on one of its planes, grinding it.

This is a delicate job, Gao Fei has been polishing for a long time, and time has passed little by little, and the groove on the long triangular pillar has not been opened, but the stone he is looking for to polish, and the sharp edges and corners have been polished.

Goofy looked at his progress, so he threw out the stone that had been polished and flattened, and then found a sharp stone and continued to grind.

Soon, the stone in his hand was smoothed again, and a shallow groove finally appeared on one of the planes on the triangular column, which gave Goofy hope, and he felt that as long as he continued to grind like this, sooner or later he would be able to polish out the triangular thorn he wanted the most.

Grinding and grinding, Gao Fei had already polished all the sharp stones he had found, and at this time, not a satisfactory groove was opened, but time was almost wasted.

Seeing that it was almost noon, Goofy had to pause for a while, and he went back to the kitchen to cook for himself.

After the pot was on fire, the coal in the stove was not burning, so Gao Fei replaced the blower with the air outlet under the stove, since the blower has been ready, it must be used reasonably.

Gao Fei was waiting, waiting for a very bored he, he looked at the blower below, and couldn't help but think of this motor, if it is only used as a blower, it is indeed a bit of a waste, he thought of a new way to polish the triangular thorns, that is, to make an electric mill.

Gao Fei felt that his brain suddenly became useful, and he was not in the mood to wait for dinner at this time, so he left the kitchen early and ran outside.

Goofy was going to look for the stones, the roundest pie-shaped stone he had imagined in his mind, and he believed that on this mountain, he would definitely find it.

Goofy searched and searched, looking for a suitable stone for him on the top of the mountain, in fact, it was not as easy as he imagined, he searched for a long time but did not find it, and finally, he thought of the stone pile that he had grabbed last time on the edge of the ice lake, and there it seemed to. There are relatively round pebbles.

So, Goofy. He went back to the kitchen to remove the blower under the stove and close the vent underneath, and then took his icebreaker and went down the hill to the ice lake.

Because this time it was deliberate, Goofy was also familiar with the road, and he soon came to the edge of the ice lake, and he rummaged through the stone piles by the ice lake.

Here are the pebbles in the team, which are more rounded than the stones on the mountain, and there are relatively few angular stones, of course, although these stones are very rounded, but what Gao Fei needs is a cake-shaped stone, and it is thin, so it is not so easy.

Gao Fei searched and searched, and finally found three stones from the stone pile, close to his satisfaction, you know, natural stones, can appear round and flat, just what he wants, it is almost impossible, can only look for relatively close, take it back and process it a little, you can make good use of it.

The next trip to the ice lake is not easy, Gao Fei can't just run this trip, just take a few stones back, it just so happens that Xiao Hei's food is not much, Gao Fei plans to catch a little shrimp here in the ice lake stone pile.

This needs to continue to open a hole in the ice, fortunately, in the stone pile area at the edge of the ice lake, the ice surface is relatively thin, and the place in contact with the stone is not frozen very strong, Gao Fei inserted the ice-breaking tool in his hand along the stone crack and inserted it down, and then pry it little by little to the side, and soon opened here, and a big hole came out.

Gao Fei started to look for shrimp, and I don't know if it was because he caught it here last time, so that the small shrimp here were frightened and left this area, and now there are fewer shrimp under the ice lake stone pile area than last time.

At least with the naked eye, it's not as easy as before, Gao Fei turned over a few rocks, and finally found a few small shrimps, although they are small, but they are better than nothing.

Goofy had to go back after spending a little time here in the ice lake, but he found that catching the blind here now was just as much a waste of time as if he had taken 10 pieces to polish the triangular column reinforcement.

It took a lot of time, but the small shrimp that I really want to catch really haven't caught a few, and there is only a small bar, a small black eats now, such small shrimp, Gao Fei has to be at least 4 to 6 at a time, and it may not be enough to make Xiao Hei full, and Gao Fei has a hand, in fact, it is estimated that there are not even 40 shrimps.

But Gao Fei didn't dwell too much on this problem, after all, he came to the ice lake, and the main purpose was to find stones, which gave Xiao Hei a little food to eat, which was just incidental.

Back at the outpost, Goofy returned to the kitchen and began to compare. The center rod on the top of the wind turbine wanted to see how big a hole the stone had to make in it, although the work was more complicated, but Gao Fei had not yet thought about how to open the hole.

The premise of the work is to make the stone completely round, this is not a person to take the eyes to roughly come out of a circle, the inaccurate circle, if it really rotates on a high-speed rotating motor, it is very fatal.

If he wants to mark the exact circle of the flat stone he is looking for, this Gao Fei still has a way, he only needs to set a center point, and then find the law of the compass, and draw a circle on it.

At this time, someone is going to say, the 913 post is so materially poor, how can there be a compass?

Yes, there is no compass available at the 913 post, but something as simple as it can be replaced by something.
