How to write the composition of ants moving?

On a recent afternoon, it was cloudy, as if it were going to rain. On the way back from school, I saw a little black thing crawling around the corner. I looked at it carefully. Yo, it's ants moving! As far as I know, before it rains, ants will remove all the equipment at home to avoid being washed away by the rain.

I squatted down to observe carefully. I saw little ants carrying their own things. Suddenly, my eyes stopped on an ant carrying bread crumbs. Every step is very difficult. Somehow, it dropped the crumbs from its back and rolled to the side of the road. Maybe this little ant doesn't have the strength to get the crumbs anymore. What should I do? While wondering, a black line appeared in front of me, which turned out to be a group of small ants. I thought: it turned out that the little ant called for reinforcements to carry bread crumbs together. The little ants gathered around the crumbs and lifted them up. The procession marched forward, and I seemed to hear their marching slogans: 12 12 1,121 ...

I was fascinated by it. If I were a little ant, I would join them.
