The biggest problem should be the difficulty of domestication, so the first step is to hit the street. We assume that we can successfully solve the obedience problem. Then: it is useless to raise one or two beasts. It is necessary to raise at least a hundred to form a scale effect. , The Thousand Days of Raising Soldiers used troops for a while, and the Thousand Days of Raising Tigers went bankrupt. If the army of beasts has been set up for a long time, catching up with the corruption of the army and deducting military pay, leaving the lions and tigers starving with green light, and a group of beasts rushing into the streets to make money, it will be exciting. Even if the troops are rich and rich, they have unlimited meat supply every day, and they have cultivated their super obedience just like cultivating war horses. Once on the battlefield, the beasts and the beasts will be able to receive orders. What if I can’t receive the enemy or I, and bite people indiscriminately? Can’t a lion match an animal trainer to rush at the enemy, right? What if the trainer died in battle? If the enemy is a ragged bandit or a peasant army, it is not guilty to use an extremely expensive army of beasts? The regular army fights casually. If the enemy is well equipped, with spears like forests, and arrows like rain, what use are the beasts in the past? If you are shot to death without armor, you can’t protect your whole body with armor. Even if your body is heavily armored and even bite your mouth, you can sprinkle some iron tribulus on the battlefield. Why do the ligers step on it? Therefore, it is not easy for humans to train elephants and horses, both of which can be commanded by humans on a one-to-one ride. Even if they are bulls, people only dare to set up a fire bull formation based on their personalities and let them attack the opponent’s position at one time. They are never conventional weapons.
