There is a lot of information that can be read from this trace, but there is very little information left, because the information that can be read has basically been discovered by Bai Zhu, and it has been compiled into intelligence and reported to Zhou Ran, and it is precisely because it has read so much information that Zhou Ran and him quickly made a judgment, and the rest is nothing too useful.

After all, there had been no fighting around here, and those primitive people would not have left traces of battle, and there would be no evidence of their identity.

After simply probing around and making sure that nothing was left, Zhou Ran planned to leave with these wild stone spearmen, but before that, he wanted to leave a small souvenir for those primitive people.

Not only in the territory where traces were left, but even in other directions around, Zhou Ran also took these wild stone spearmen to set up some traps one by one, the power of these traps was very large, but the range was very small, and it could only have an effect on a few of them at a time.

And Zhou Ran didn't leave too many numbers when he set them up, but he appropriately widened the distance between these traps and traps, when these primitive people came again, they were likely to touch a trap and cause a small part of it, or a few people to die.

The very low rate of casualties will not attract too much attention from these primitive people, they will only slightly lift the process of mental progress, and be a little more careful, and they tense their nerves for a while, and after advancing a very long distance, they will subconsciously relax their vigilance again, and at this time they will trigger the second trap, this time the trap set by Zhou Ran is powerful, but the range is smaller, and the damage rate will only be lower than the last time.

Although this will attract the attention of the primitive people again, it is not enough to make them retreat, and Zhou Ran's repetition in the subsequent trap will make their spirits constantly experience tension, relaxation, fright, tension, relaxation, and fright.

Among the several traps close to the territory, the traps set by Zhou Ran can not only cause damage, but also release a very sharp and loud sound like a whistle.

It was quite a warning in advance, so that these primitive people, who were already very nervous, heard this loud sound, either immediately dispersed and fled, or they fell directly into panic, no matter which one it was, when Zhou Ran and the others carried out a surprise attack, they would definitely be able to take them down in one go.

However, the success of this matter is based on the possibility that these primitive people will come to explore Zhou Ran's territory again, but Zhou Ran feels that this possibility is not small, after all, although the last exploration of these primitive people took a while, but in fact, the traces they left are only in the west of the territory, and this trace is not too long, and it is far away from the center of the territory, which means that unless they have a few clairvoyants, they will not get too much information, and they will inevitably carry out the next exploration.

After taking care of the matter here, Zhou Ran rushed back with Liu Qingkong and these stone spearmen, and he instructed Liu Qingkong to change the patrol team from the original one team to three teams in the next time, but the number of each team should be appropriately reduced.

In addition, he also made some simple whistles, no way, now there are no craftsmen in the territory who want to make these gadgets, so the lord Zhou Ran can only go into battle himself.

At this time, he found out that this kind of simple bamboo whistle, other people in the territory still can't make it, only he and the old man know a little bit, Zhou Ran is because he learned a little bit from a craftsman in the territory in his previous life, because he is very interested in forging and craftsmanship, and the old man is because he has lived long enough.

In the boring era of the Beacon Age, the only thing that can be used as a pastime is to learn all kinds of things besides fighting, the old man has lived for so long, he will always learn some various things, and if he wants to ponder these things repeatedly, he only needs to enter the dream gap to study, and naturally he has mastered quite a lot of skills.

Divided into three patrols, the stone spearmen put on the newly made bamboo whistles, and began to patrol around the territory, under Zhou Ran's orders, their patrol range appropriately suppressed some of the original closer to the center of the territory, that is to say, the patrol range has become smaller, this is done so as not to alarm those who come to investigate, if the patrol range is too poor, it will further force their original exploration distance outward, and there will be no way to use the trap set up at that time.

The matter here is done, and the 72 hours are still very early, Zhou Ran first covered his head and fell asleep, and after waking up early in the morning of the second day, he gathered the blind boxes collected by others who went out hunting, and then it was the most exciting time to open the blind boxes.

But this time, no matter who went out hunting, all the encounters were ordinary primitive tribes, and the wild units were only elite-level, and not a single quasi-hero-level or even hero-level one appeared, so the blind boxes obtained were all lowest-level bronze treasure chests, and none of the crystal balls and scrolls appeared.

Fortunately, the number of blind boxes is not small, the 4 squads have harvested 30 blind boxes, which mainly minus the blind boxes that Zhou Ran opened in advance in order to cure those soldiers, he almost opened all his blind boxes in that incident, so these 30 blind boxes were actually only collected by the other three teams.

There are more than 30 bronze treasure chests, and the probability of the treasure that can actually be opened is not large, and Zhou Ran did not have anyone to open it in the bamboo shed, he called Liu Qingkong and the old man all over, this time he wanted to see how the old man's luck was.

However, I don't know if the three of them are black, or if the quality of this batch of blind boxes is not good, the three of them opened half of the blind boxes in one go, and only two blue lights burst out, and these two blue lights are all resource items, one is 150 units of black stone, and the other is 50 units of tiger skin.

Holding his breath again, he opened all the remaining 15 bronze treasure chests, this time Liu Qingkong burst out of a purple light, but unfortunately this purple light was not used for a while, because this was a drawing that only carpenters could use.

Zhou Ran took the drawing and studied it carefully, and nodded thoughtfully, the value of the drawing itself is not low, but before there is no carpenter, they have no way to use it.
