In terms of intelligence, apes are the easiest to domesticate, but apes have the same ability to obtain food as humans. It is better to raise a few more children than to raise orangutans, so apes are excluded from the species chosen by human domestication.

Large carnivores are excluded because they are in a huge amount of food and cannot be maintained, and secondly, they are difficult to control.

In fact, in terms of hunting efficiency, the canine family is much higher than the beasts such as lions, tigers, and leopards. Moreover, the canine family has strong endurance, which is similar to humans in this regard and can assist humans in hunting well. Although large carnivores are very fast, they are actually far inferior to humans in terms of endurance.

The beasts have limited help to humans in terms of food consumption and predation efficiency, so before aristocratic class was formed, they were also excluded from the choice of domesticated species by humans.

Walking upright is actually a way of exercise that consumes the least physical strength. After completing the evolution of walking upright and learning to use tools, humans stand at the top of all food chains in nature.

Evolution is actually a choice of the best choice in terms of energy consumption efficiency.

With the changes in the world, the source energy is restored, and the era of cultivation has arrived, the ability of practitioners to control ferocious beasts has increased greatly, and the choices of pet animals they raise have become more diverse.

However, breeding and domestication are two completely different concepts.

The development of beast control technique is mainly about the control of wild beasts, and the most advanced one is taming.

But domestication is a long-term, repeated screening process, and the species selected also requires that the ethnic group be large enough, and it takes almost thousands of years to complete.

However, this kind of domestication involves the economic benefits of input and output, and returns to the choice when humans began to domesticate wild animals.

Therefore, since people's original intention of learning beast control is a speculative choice, the so-called highest level of taming technique has no practical significance.

The conditions for choosing alien beasts to assist in combat are very high. First of all, it is easy to tame and obey and rely more on humans. Secondly, it is growth. Low-level alien beasts do not help much in fighting between masters. In addition, loyalty and reliability. The alien beasts tamed by beast masters abandon their masters and flee and even retaliate against their masters when the battle is most intense. They also happen from time to time.

In fact, there are not many strange beasts that can meet the above conditions at the same time.

High-level alien beasts are extremely difficult to tame. Most adult ferocious beasts and raptors are very eager to die and never surrender, so they must be cultivated from an early age. Once some powerful alien beasts recognize their masters, they are extremely loyal and rarely betray them. Such alien beasts are called spiritual beasts, but they are hard to come by and are currently very rare on the Red Flame Continent.

This brings us back to the multiple-choice questions that humans first tamed wild animals.

Ling Li and Liang Xiaotian entered a shop and saw more than a dozen ferocious beasts in large iron cages, including polar silver wolf, black bear, lynx and snow dog. Occasionally, a low roar would be made in the mouth of monsters, which obviously had not been tamed.

"It's all four or five levels of strange beasts." Ling Li looked at the strange beasts locked in the iron cage. Except for a polar silver wolf who could grow to the sixth level, everyone else was already considered adults and had no growth potential.

Ling Li’s target is only a strange beast that can advance to level seven or above. It seems that it is very difficult to buy a strange beast of this level on the market.

"Are there any high-level flying beasts?" Ling Li looked at them for a while and asked.

"There are a few ordinary carrier pigeons and hunting falcons, but high-level flying beasts are difficult to capture. There are very few pet animals on the street. Every time they appear, they will give priority to supply important customers. Flying beasts with good growth will basically not be placed on the street to sell them." The owner replied.

Ling Li sighed slightly in his heart. It seemed that the strange beast of this level had to be captured by himself.

He was about to leave, but he found a clerk walking out of the animal breeding room in his arms with a cat-like beast in his arms. The cat-like beast seemed to be sick, listless, with messy furs, and his ears were drooping. However, his half-open small eyes were full of alertness and looking around...

"Huh..." Ling Li stopped and his eyes lit up.

"Boss, this little lynx is sick and doesn't eat at all. Should you carry it over to see the veterinarian?" the clerk said to the shop owner.

"No, just feed some anti-inflammatory drugs, life and death are alive." The owner said, "The veterinarian's medical fee is too much. It's embarrassing not to buy medicine from him. It's just a lynx, it's not worth it..."

The shop owner obviously didn't want to spend too much on this cub, but... he thought this little thing was a lynx?!

The lynx is a cat animal that is bigger than a cat and smaller than a leopard. At most, it can grow to the third-level alien beast, and only a very small number can advance to the fourth-level.

Although this cub looks like a lynx and has not been weaned, it is already a third-level alien beast, but it is an alienated snow-mounted leopard cub. Where is the lynx?

Due to the system, Ling Li generally does not admit his mistakes in this regard.

The owner obviously did not realize this.

"This lynx looks cute and feels very good. I raised it by myself?" Ling Li said.

"No, a nest of cubs picked up by a pioneer team in the mountains a few days ago. They have not been weaned yet. It seems that they have only been more than a month." The owner said.

"A nest?" Ling Li asked with some interest: "How many more?"

"There are five in total. The pioneers picked up the adult lynx in a cave, Longyan Mountain, but they didn't see any adult lynxes." The owner said, "When they first came here, these little guys looked hungry for several days."

Ling Li was overjoyed and thought that if the adult ice field snow leopard was at home, the entire pioneer team might have been wiped out. These people would be really lucky. Ordinary snow leopards could advance to level seven, and this alienated cub was obviously more capable of growing. Such good things were hard to come by, so he naturally would not let them go.

"The little guy looks quite cute. This time I came out, I didn't know what gifts to my little sister. I think it's good to buy them as pets." Ling Li said, "How much does this lynx cub cost?"

The shop owner looked at Ling Li, "If you really want it, you can have fifty lapis lazuli, this one is a little bit wrong."

Ling Li thought about it and remained silent on her face. "It should be that the animal milk I was fed was a bit deteriorated, which caused enteritis, and it was not a big deal... I'll take a look at the others, maybe I'll get them all."

The shop owner turned to the young clerk who was only about twenty years old, "Acheng, go and bring all the other four cubs over."
