Chen Mo was very worried about the safety of the pontoon.

There was such a big movement, it was impossible for the tribes on the other side of the river not to know about it.

The navy tribe is in the light, and the unknown tribe on the other side is in the dark, and when the situation occurs, the navy tribe is the most passive.

Therefore, Chen Mo mobilized thirty people to garrison across the river, led by Hei. Black's mind is meticulous, and tonight's garrison should be foolproof.

Although almost all primitive people now have night blindness, it cannot be ruled out that some tribes have gotten rid of night blindness, and Chen Mo is worried about this problem that cannot be ignored.

Chen Mo didn't sleep at night, and he kept doing ideological work for the tiger master.

The thoughts between people are easy to do, know them with affection, and move them with reason. It can even threaten coercion. But between man and primitive creatures, this is embarrassing.

Reasoning, it doesn't understand, threaten, you can't beat it......

"Master Tiger, cross the river, really, after crossing the river, eat the flower chicken!" Chen Mo said with a flattering face.

The delicacy called flower chicken not only conquered the tribe's people, but also conquered the tiger master.

Hu Ye ignored Chen Mo, turned over, and continued to lick his paws.

Chen Mo is very familiar with this action, every time the tiger licks his claws, then Niuniu must be fanned. But Niu Niu is not in the house now, so there is only one target left...... Chen Mo.

Chen Mo quietly took a small step back.

"Master Tiger, let's talk in advance, don't do it!" Chen Mo said a little worriedly, but he felt that something was wrong.

"Master Hu, let's try not to move, don't do anything, let's be reasonable, I'll tell you the benefits of crossing the river again! Forget it, don't talk about it, if you don't go, forget it." Chen Mo saw that the tiger master was a little impatient, and immediately stopped his mouth.

......

......

Hei attaches great importance to the task of defense, and although there are thirty troops left behind across the river, Hei is worried about the unknown at night.

The people of the clan consulted Chen Mo, and then transferred the thirty people on the other side of the river to fifteen people.

The purpose of the remaining tribesmen on this side of the river was to support the other side of the river and warn them. But it was unrealistic to run on the suspension bridge, so Chen Mo agreed to transfer fifteen people from this side of the river to the other side of the river.

With more than 40 resources to mobilize, Hei immediately assigned his own tasks, set up a secret post and a clear post, and formed two groups of patrols to patrol the surrounding area of 50 meters without stopping.

Many times, Hei is more thoughtful than Chen Mo, in Chen Mo's words: This is a qualified commander!

The patrol team found the skeleton of an animal not far away, and immediately reported it to the black.

The skeleton was nearly 50 meters away from the bridgehead, and due to the darkness of the night, the patrol team also found it after many inspections.

Hei picked up the bone and looked at it carefully, the meat on it was a little smelly, the time was not too long, and now in early summer, the meat spoiled in most of the day.

"Hurry up and report to the chief, there are traces of human activity here, just yesterday. Black whispered to the people next to him.

As the people walked across the bridge, Black increased the number of dark sentinels, and his instincts told him that something was going to happen tonight.

"You quietly go and tell them not to fall asleep tonight, pay attention, something will happen at night. The black order was arranged, and the left-behind tribesmen also consciously gathered around the fire, while the patrol team was more careful.

As we approached midnight, the jungle was silent, except for the sound of patrols walking by, not even the most basic insect chirps, which was very abnormal. At the same time, Black's perception of danger is getting stronger and stronger.

Just as Hei was listening to the sounds around him, he heard the sound of rustling not far away.

"Someone's coming!" Black hurriedly stood up and pointed to the jungle where the sound came from, shouting, "Throw the bone spear!"

"Whoosh", "Whoosh" The clansmen who had already been prepared raised their bone spears and threw them in the direction of the black fingers.

"Ah~" A few screams rang out in the jungle, and then a few bone spears fired back at the sailors.

Except for one unlucky man, no one else was injured. The black face sank, and he shouted to everyone: "Disperse, throw!"

This time, in order to ensure the long-range combat effectiveness of the team, Chen Mo deliberately prepared five throwing bone spears for each person, and the people who stayed behind were all clansmen with very accurate throwing skills.

Although the tribe has a bow, it is not powerful, and the range is only the most powerful at more than ten meters, so it can only be used when defending at close range, and it is most appropriate to use a throwing bone spear for long-range attacks.

Each clan also had four throwing bone spears on their backs, which they were scattered to throw at the place where the bone spears were fired.

The second wave of attacks arrived, and the continuous screaming stopped.

Black continued to give the order to throw.

There was a murmur in the jungle, then silence returned.

Hei stretched out his hand to stop the clansmen who were about to throw the bone spear, and led the clansmen to the place just now with the tooth spear. The first few clansmen lit torches.

The torches were invented by the wind, and the wind patrolling at night felt that his vision was affected, so he developed it for a few days based on his previous experience, first boiling the fat of the deer into oil, then tying it to the top of the wood with dried rattan, and then dipping it and lighting it. This led to the invention of the torch.

Such torches can be used for nearly an hour, and the brightness is also very high, and the practicality is very high, so it became popular among the tribes.

There were three men lying in the woods, covered with bone spears. There was a lot of blood on the side, which continued into the dark jungle.

Hei looked at the blood stains on the ground and judged that there were at least three people's blood stains, and the traces on the ground were in the appearance of more than a dozen people.

"Collect the bone spears, let's go back, the patrol team will not come out to patrol for the time being, change to a secret sentry, scatter around, don't make a noise when you come, and copy it in the back." Kuro thought for a moment and ordered.

The people pulled out the bone spears from the trees and the ground, inserted them back into the ropes on their backs, and slowly retreated to the fire. The patrol quickly dispersed and dispersed to hide in the surrounding trees.

Hei felt that there would be no more attacks in the first half of the night, so he arranged for the clansmen to sleep in groups, close their eyes and recuperate, and pay attention to the sounds in the jungle at any time.

The second half of the night was quiet, and when it was getting lighter, the jungle was again filled with the sound of ropes.

Black listened carefully, it was the sound of objects, those people carrying the bodies of dead people. Black didn't give the order to attack, just kept on guard to avoid unknown dangers in the jungle.

The sky gradually brightened, and Chen Mo led a large army of the Navy tribe to the scene, but the Tiger Master family did not follow.

Hei found Chen Mo who came and began to report the situation: "Chief, about a dozen people, we shot three to death with bone spears. ”

Chen Mo nodded and walked towards the place where the battle took place last night.

Now the sky is bright, and the traces of the ground are fully visible.

"It's a group of people, like the people of our tribe, who can see things at night. Hei saw Chen Mo squatting down, broke the silence and said.

"Well, this group of people may have been waiting for us here, I showed Uncle Pi the bones you asked the clan to bring back last night, and Uncle Pi said it was the prey at noon yesterday. Chen Mo picked up a stone on the ground and said.

"So they were already here when they crossed the river?" asked Hei curiously.

"The leaves and branches on the ground are wilted, and they certainly didn't fall off last night. Chen Mo put the stone in his pocket and turned around and walked towards the river.
