An Su looked at the deep pool, frowning and thinking deeply while twisting the water on his clothes, that monster was obviously here to help them, but why did it appear there? All she had seen before was a human figure. The pen "Fun" Pavilion www.biquge.info and the voice, although hoarse, but speaking the lingua franca of the Federation. Could it be—Ansu suddenly had a bold guess.

An Su's gaze inadvertently swept to the mural carved into the cave wall. The frescoes are very old, some of them have been corroded, peeled off, and mutilated, but some can still be discerned in general. The theme of the mural is mostly about hunting, and it can be seen from the variety of animals that the Omanrans with their tails raised are chasing them. Although it is only a few strokes, the powerful lines bring the characters to life.

The mural also records the Amanra's sacrifice to the god of fire, among other important ceremonies, and Ansu noticed that the Amanla stood tall around the central pillar, which appeared to be particularly large, and there were runes carved into it that she was familiar with. Ansu stared at them as if she wanted to see something from them.

The sun rose higher and higher, and a circle of gold edged the entrance of the cave, and a beam of sunlight passed through the corridor and shone on the runes, painting them a layer of golden red, as if they were about to burn. Ansu's mind suddenly flashed to the cylinders underground, but unfortunately he glanced at it in a hurry and didn't see what was on it.

Temo walked over and followed Ansu's gaze to see the mural on the wall.

"It's a ritual to worship the god of fire, and it won't be long before you can see it." After saying that, realizing that Ansu couldn't understand his words, Taimo scratched the back of his head helplessly.

After a day of tossing, both of them felt tired, Ansu was mainly mentally tired, while Taimo was physically tired. They struggled to climb the cliff and found a place to rest on it.

This time, it was Ansu who used the techniques he learned from Taimo to catch the two fat gophers, and Taimo was in charge of collecting firewood, but unfortunately his flint and stone knives were lost in the ground, and it was Ansu who started the fire. For the first time, Taimo saw the most primitive method of making fire that their ancestors could have used - drilling wood to make fire, and it was possible to make fire out of wood!

They rested for a while, and gradually regained their strength. Ansu decided to stay here a little longer, wanting to continue exploring the intricate caves. Temo first went back to report what the Samba patriarch had learned, and then equipped himself with new weapons.

When Taimo's figure disappeared into the distance, the expression on Ansu's face became solemn. The mysterious base that appeared underground turned out to be human! This discovery made her heart flutter again, could this be the secret base of the Federation? And who is that human who suddenly appeared? Why did you avoid them when you saved them?

Ansu stood on the cliff and looked at the rolling water below, narrowing his eyes.

Ansu built a simple shelter here, but the vegetation here is sparse, the trees are relatively short, and most of them are shrubs, which cannot bear her weight, so Ansu built a single-slope shed. She lifted a dry tree trunk and put it on the thicker branch, so that the trunk, the ground, and the dwarf tree showed a right triangle, and then used the dead tree trunk as the beam, and found some branches to put on the dead tree trunk at one end, and the other end on the ground, and spread a full side, which was strict and solid, and there was no need to worry about rain.

This place chosen by Ansu is more ingenious. There are a few rocks in front of the low trees, just to keep out the cold wind that blows from the direction of the Great Rift Valley at night. There's no grass around, so don't worry about an ambush. A fire is lit behind a pile of rocks in front of the shed, and the heat of the fire is reflected back like a mirror, which is a simple heat reflection device. If you don't feel safe enough to burn a fire, you can divide the fire into smaller piles to form a wall of fire. When you sleep, you will feel much more at ease and warm when you lie in the shed.

For Ansule, a fire, a shed is enough.

Since she planned to spend a little more time exploring the caves of the Great Rift Valley, Ansu didn't want to spend too much time hunting, so she carefully examined the terrain around her and chose the right place to set a trap.

There is a path that often occurs in places where animals often pass, and this path is often the most convenient and labor-saving route, and wild animals know how to minimize the energy consumption of their bodies in nature. When a person walks in the wild, he can follow the path that these beasts have taken, but be careful, these paths may also be taken by beasts. Also watch out for traps set by hunters. Danger can also lurk in the convenient way.

Ansu observed that most of the footprints on the ground were hoof prints, and there were some paw prints, which are characteristic of cats, and plum blossom prints that are unique to cats have not yet been found. In this grove grows an antelope from the Great Rift Valley. Their most striking feature is a pair of large scimitar-shaped horns, sharp and sharp, especially majestic in males, with a pair of horns almost equal to the length of their bodies, making up for their relatively short legs. Their legs are thick and short, and the front of their hooves can be flexibly spread to climb cliffs, and they return to the bottom of the Great Rift Valley during the dry season. The first thing Ansul notices is the unique mark left by their open-door hooves.

As for the paw prints that look like bamboo leaves, Ansu thinks it's more likely that they are gophers, and of course they may have been left by some kind of rodent.

After evaluating the terrain and the types of animals, Ansu decided to set up a rope trap and a falling object trap, the former can be placed for a long time, but it is not easy to trigger, and it needs to be set up with a trigger mechanism, and the latter is more lethal but easy to trigger.

To set up a rope trap, you need a rope, but unfortunately Ansu's animal skin bag with rope was lost in Red Hill, and the tendons of those sea lion beasts are very suitable for rope holdings. There was no rope available, so Ansu peeled off the bark of the dwarf tree and rubbed the rope.

The branches of these dwarf trees are as flexible as willow branches, which can be used as a source of elasticity. Ansu found some branched tree poles and processed them into pairs to make a trigger. One end of the rope is tied to a bent branch, and the other end is tied with a looper. An R-shaped tree pole is tied a little away from the upper part of the loopk, and the other tree pole is inserted in the opposite direction, and the branches of the two tree poles intersect in opposite directions to form a stable structure. When the prey walks into the trap and touches the noose, the intersecting branches will stagger apart, and the branches will bounce up and tighten the noose at the same time, and the prey can be caught.

The Falling Object Trap actually uses the principle of falling objects from high altitudes. First of all, you have to choose some lethal stones or tree trunks according to the size of the prey, and support them with tree poles, the other end of which is sharpened and stand on a touching pole placed on top of the stone or dead tree trunk. When the prey eats the bait placed on the trigger rod, the trigger rod slides away and the wood or stone that has lost its support falls down.

Ansul has several traps of each type to ensure that at least one of them is rewarding.

Set the trap and Ansu explores the mysterious caverns again, determined to get the human out. Since he has the fluctuation of the chip's energy, it is very likely that he is from the military or the research institute, and the chip was originally developed by the people of the research institute, and they are also the first batch of users. In the past images seen on Flame Island, the people of the research institute have indeed been to this planet.

An Su looked at the mysterious Great Rift Valley under the starlight, his face was cold, is this the secret base of the research institute hidden?
