After letting go of this primitive man, Zhou Ran didn't let him leave directly, how could he suddenly be kind enough to let go of a captive? He was let go to test his medicinal properties.

Before letting go of this captive, Zhou Ran explained to him that it was okay to let him go, but after letting him go, he couldn't put other references around his territory, and he couldn't tell his lord about the information about his territory after he went back, this primitive man promised to be good at the time, but after leaving Zhou Ran's territory, or not leaving Zhou Ran's territory, he had just left the circle in the center of the territory, so the primitive man looked around and picked up a few stones from the ground casually, I set up a reference.

It's not that this primitive man is backsliding, mainly because he can't do this kind of thing with his brain capacity, in fact, he was really sincere when he promised Zhou Ran at that time, but this sincere thing, after he left the territory, has been forgotten in the back of his mind, and then after seeing the stones on the ground, he remembered the task assigned by his chief before, and subconsciously picked up a few stones from the ground and built a reference.

When the village house was erected, the surface of the primitive man's body suddenly bulged one after another, like small blisters, and these blisters began to expand rapidly, and soon changed from the size of a little finger belly to the size of a ping-pong ball, and then began to move everywhere under the primitive man.

The primitive man showed a very frightened expression on his face, in the primitive era, most of the diseases did not have effective medicines, so after getting a disease that could not judge its symptoms, it can only be seen whether this primitive man is of great use in the tribe, if the use is big enough, then maybe the witch will find a way to make some medicine for him, or cast some witchcraft on him to make him successfully recover, but if the effect is not great, then he can only obediently wait for death.

And this primitive man obviously belongs to the kind that has little effect, and even if it really has some effect, he will definitely not wait to return to his territory, so he immediately let out a scream and began to flee in all directions.

But before he had run two steps, the small bulges on this primitive man were already swollen to the size of a fist, and his face showed a look of despair, and before he could even say half a word, he instantly exploded, and the surging impact even lifted the surrounding ground into the air.

Zhou Ran, who was sneaking behind this primitive man, swallowed his saliva when he saw this, this power is also a little scary, although Zhou Ran asked the old man to make it when he made this medicine, and even the effect was thought of by him, but the effect made by this old man was too scary.

And this is what the old man said, because the materials and utensils are not complete, the effect of making it is much worse, if you really make 100% of the finished product, even if it is a top totem warrior who is hit by this, it will definitely not be good.

On the contrary, the old man on the side stroked his beard, he frowned, his expression was slightly dissatisfied, Zhou Ran didn't dare to ask more, but just looking at the old man's expression, he could roughly guess what he was thinking, probably he was not very satisfied with the effect of this potion.

After confirming that this medicine was really effective, Zhou Ran was relieved, this time he went back and released all the 4 captives, but what he ordered to the 4 captives was not to ask them not to set up references, in this case, maybe they would have an accident halfway, so what he ordered to these 4 captives was not to reveal to their chieftain or Wu about himself.

Although these primitive tribes sometimes have a large number of people, as many as 1000~2000 people, their management division is only three levels at most, one is ordinary people, that is, those who stay in the territory, the elderly, the thinner women, and the children, this is the lowest level.

The middle level is the hunting team, the patrol team, the group of people responsible for fighting, as for the highest level, it is the chief or witch, and even most of the time the identity of the witch is so high and a half layer higher than the chief.

And these captives are all second-level patrols, if they are responsible for reporting intelligence, they will naturally not report to their so-called squad leader, squadron leader, captain or the like, after all, there is no such division within the primitive tribe, they will report directly to their own chieftain or house, if the four of them report together......

A smile appeared on Zhou Ran's face, just now he saw with his own eyes the power of the primordial potion after it took effect, and that impact directly made the turf in the range of about 10 meters in diameter disappear, and a stone in the range was directly blown into pieces.

The human body theoretically can't withstand such an impact, but that refers to the ordinary human body, and the physical fitness after strengthening is barely able to withstand such an impact, in the case of Zhou Ran, if he is within that impact range, at most he will suffer some minor injuries.

But that refers to one impact, if the four impacts are added up, even if Zhou Ran's current physical fitness, covering all the neutral internal qi on the surface of his body, he will be seriously injured, unless it is transformed into mixed element internal qi, with the strong defense of mixed element internal qi, it can barely guarantee that he will not be too seriously injured, but he thinks that those chiefs or witches should not have such a powerful means as mixed yuan internal qi.

Even if they had, they would definitely not show it when their patrol reported intelligence to themselves, the more they thought about it, the more satisfied Zhou Ran cleanly let these 4 primitive people go, as for the remaining dozen or so captives, Zhou Ran also gave them medicine one by one, and even asked the old man to take a hand to recuperate their injuries a little.

These dozen primitives, Zhou Ran didn't plan to let them go immediately, it was enough for the 4 primitives to go back, if these dozen primitives went back, they would definitely stagger the time with the 4 primitives, and when the time came, the four of them had reported information to the chief once, and there had already been an accident, so if the chief had a little wisdom, he would definitely not have close contact with these dozen captives casually.

Therefore, Zhou Ran planned to let them take care of their injuries and die for the time being, and if the hero tribe really sent troops to attack him, and then let these dozen captives pretend to meet them in an internal way, and then there will be a wave of meat, eggs, onions, and chickens, and more than a dozen impacts will be superimposed together, which is enough to cause extremely serious losses to the opponent's troops, and if they are lucky, they may be able to end the battle at one time.
