I used to raise large livestock in the countryside for a while.

Cows are strong and have great endurance, and can do very heavy work, but in reality, they are not very efficient because they work slowly.

Horses can run and pull, but their endurance is very poor. If they work hard for a long time, they will lose their strength.

Donkeys are good animals, with moderate speed and endurance, but they are very stubborn. Once they get angry, they won't move for a long time and will even throw a tantrum. When such a big animal gets mad, it's no joke.

A pig is a treasure from head to toe, but it has to be slaughtered before its meat can be eaten and its skin peeled off, which it cannot do. If its food and living conditions are poor, it will not gain weight and will be more prone to illness.

Take food for example. If you want livestock to grow well, they need to eat a lot. For example, when feeding cattle, the old farmer who led the way took me to cut grass early in the morning and told me which grass was edible and which was not. Not all grass was edible, and too wet grass was not edible. Generally, around 10 o'clock in the morning, the grass was fresh and tender with almost no dew on it, which was the most suitable for feeding cattle. It really opened my eyes.

Not to mention living there, anyone who has done the job of cleaning the pig sty or cattle pen knows how hard it is.

After a few days, I was so tired that I felt dizzy and felt that raising livestock was not easy.

Once I was exhausted and I thought, could such a kind of animal be evolved: with low requirements for living conditions, little food, poor living conditions, able to treat itself when it is sick, able to actively create wealth for me (fast weight gain), able to work, high efficiency, little or no rest, good temper, and preferably a low IQ. If there really is such a thing, it would be the most highly evolved animal on earth. Unfortunately, I have not been in the countryside for a long time and have limited experience, so I have never seen it.

Until I saw my reflection in Tantou...
