But he can teach them some language, inviting them to communicate, just the most basic communication is enough.
The simplest communication is 'should you eat me or not'.
Learning this language well can spare your life, while failing means you deserve to die.
He hopes enough wild animals around him can learn this language. If a tiger, two leopards, and three wolves all understand how to negotiate with him, the future days will be much safer and more worry-free.
He must try to make sounds to them, the simpler the better, with emotions inside to encourage them to respond. As the communication becomes extensive, they can live together.
Then a society will be formed, he will become the ruler, establish order, expel intruders, punish, exile, or execute animals that do not follow the order.
This is a way of thinking, and it is an exceptional and practical one. Learning the trick takes a lot of time and effort.
The key is how he can learn to talk with wild beasts.
