Manman thought for a moment and said, "You can go down the underground river, I know that there is a huge underground river, which also extends to the east, and I don't know if it goes all the way to the sea, or some other terrible place. Moreover, there are quite a few 'siwa' living in that large underground river, and of course, I believe that this thing poses no threat to the gods. ”

Muma hastened to tell David about the situation.

David was overjoyed when he heard this: "That's great, so that you can hide from the enemy's aerial search." Muma, you tell Manman, tell a few warriors to go to the bottom of the waterfall to look for it, see if they can find the rubber boat, I guess the enemy will not go into the water to salvage, they are so afraid of death. ”

Upon further investigation, David learned that the waterhole in front of him led to an underground river, located not far from the waterhole.

The cave below the waterfall also has some relatively large openings, leading to this underground river, and this underground river goes northeast, and floats for half a sleep (about five hours), which is the larger underground river that leads to the east.

David then asked Muma to tell Manman to find the dinghy and transport it to the underground river next door to the cave.

Next, Manman's warriors found the rubber boat at the bottom of the river a few kilometers downstream of the waterfall, and the air inside the boat was already dry.

After receiving this news, Muma hugged David and led by Manman, and dived to the underground river.

Without glue tinkering, the dinghy wouldn't have been inflated, but David tried to start the engine and it was still running.

Because it is drifting, it will not always start the engine, and according to the original five or six hours of battery life on the rubber boat, it can still be improvised.

In the next few days, Mu Ma and the "households" went to the surface, searched for and cut down dozens of wooden stakes of different varieties, different densities, thick bowls, two meters long, and a hardwood stick about two meters long with the thickness of Mu Ma's wrist, and dragged them back to the underground river one by one.

When Muma was supervising the work of the "households" on the ground, he was bored and wandered around the dense forest nearby, and saw a small hill nearby that was more characteristic than other mountains, and there was a bare boulder with a square and slightly flattened on the top of the mountain.

Tilting his head and thinking for a moment, Muma found a plantain-like plant nearby, tore off a large leaf, and trotted all the way to the top of the hill and the boulder.

After looking left and right for a while, Muma picked up a thin branch from under the bush next to him and wrote and drew on the large leaf.

Then I picked up many small pebbles on the side of the boulder, threw them to the top of the boulder one by one, and climbed up to get busy... Then quietly return to the "household" monkey group.

By the underground river, David taught the Tima to use a knife to cut the leather of the "Siwa" and "Gecko" into thin ropes, and then taught the monkeys to use leather ropes to tie the wooden stakes tightly together, the wooden stakes are arranged in three layers, the bottom layer is the twelve most dense wooden piles, the second layer is the eleven wooden piles of medium density, and the first and the top layer is the ten wooden piles with the lowest density, and so arranged, forming a raft with a low center of gravity and not easy to roll over.

The front of the raft was then made into a triangle with a stone axe, and the engine and battery pack of the rubber boat were fixed to the tail of the raft.

The original black skin of the rubber boat is then cut, spread on the surface of the raft, and fixed with wooden nails. These skins are wired inside, like electric blankets.

David taught Tima to pull out the remaining wires in the skin of the dinghy as a wire, connect the wires in the skin with the function of solar panels with the battery pack, and after a little try, after returning to the surface water surface to be exposed to the sun, it should be able to charge the battery.

The stick, which was as thick as Muma's arm, was trimmed and used as an oar or pole.

Finally, cut two pieces of "Xiwa" leather, one large and one small, and nail the leather to the raft with wooden nails, just enough for Muma and David to poke most of their bodies into it, which can prevent the rapids or waterfalls from causing the two monkeys to be thrown out of the raft and play the role of a safety belt.

In order to prevent Joseph from establishing a slave empire, David has thought of many plans in recent years.

The first plan is to infiltrate the communication room of the base, send the current situation to Earth, let the United Nations launch nuclear weapons to wipe out all the creatures within hundreds of kilometers of the base and the surrounding area, and then formulate and implement a stable colonization plan that can prevent the advance army from mutiny. But one is that Earth Headquarters believes it or not, and the other is that Joseph sees David to death, and the plan cannot be implemented.

Plan 2 is to escape first, and then find a way to sneak back to the base to implement Plan 1. But first of all, Joseph has many associates on Earth, and even if the United Nations can believe David's message and pass the resolution to launch nuclear weapons, the result of the resolution will definitely soon reveal to Joseph that the speed of radio waves can be many times faster than the speed of nuclear shells, and Joseph can easily escape with the rebels to hide anywhere on Proxima Centauri. And bomb the entire surface of Proxima Centauri B? People can also hide deep underground. And it will destroy most of the creatures on Proxima Centauri's surface as a result, which is very uneconomical.

Plan 3 convinces Lulu to help kill Joseph and the other rebel leaders. But Lulu herself is a vested interest, secretly hiding weapons for David, in fact, she just wants to give him freedom, that's all, want her to prevent herself from becoming a queen? No way.

Therefore, it is basically impossible to rely on the United Nations and others in the base, and you can only rely on yourself.

David is now powerless and has about a dozen years left to live.

Spending time with Muma every day made David think that he could use Muma's clan to help him.

Unexpectedly, before reaching the beach, a small tribe of water monkey "households" was incorporated, and David thought that it would be okay to continue to incorporate all the "households" in this area.

But he could see that Muma was hostile to the "Huhu" ethnic group, and wanted to "arm" the "Huhu" ethnic group and improve their civilization, and Muma would never agree.

Mulma has helped her so much, do you want to abandon her and use the "household" group instead? David thought he couldn't.

In the next few days, the warriors of the "Hudo", under the leadership of Manman, smoked a large number of dried meat of "Siwa" and "platypus", made new leather quilts for David and Muma, and wrapped various materials with a large dark green leaf and fastened them to the ship with leather ropes.

When everything was ready, David and Muma bid farewell to the Omani tribesmen who collectively knelt in a long line on the banks of the underground river and began a new journey.

After drifting for more than five hours in this underground river, which is about seven or eight meters wide, David and Muma felt that the current suddenly accelerated, and then the wooden boat jumped slightly and rushed into an even larger underground river through a small waterfall more than one meter high.

Muma quickly stabilized the hull of the boat with the wooden stick, allowing the boat to continue down the river.

This underground river is about 20 meters wide, the water flow is slightly gentler than the previous tributary, but I don't know if there will be rapids and waterfalls along the way, according to Manman, the waterway to the east is more than 100 kilometers very smooth and easy to walk, "Xiwa" is not too much, but after that it is unknown.

Of course, the concept of how many kilometers was calculated by David himself through Manman's description of time and the speed of the water.

After the two monkeys walked more than 100 kilometers, there was no danger all the way.

The next step was to enter the waters beyond Manman's knowledge, and David decided to land first to let Mulma rest.

After tying two leather ropes to a large rock on the shore, Muma ate some jerky, spread out a "platypus" skin quilt on the ground, and began to rest.

David, because he could also nap on the boat while sailing, took on the task of keeping watch at this time.

At the same time, at the bottom of the underground river, a mysterious and unpredictable flood force is quietly thinking about whether to rush out of the water.

Listening to Muma's increasingly snoring sound, David leaned against the stone where the boat was tied, and ate the "Siwa" jerky without a bite, and his thoughts returned to Earth again.

It has been more than twenty years since his soul left the earth.

Based on Eva's physical condition at the time, she should have been in the database for many years.

When David died in a car accident at the age of 62 in his first life cycle, and his wife Eva lived a long life, still in her 90s, so after David's resurrection, the two seemed to be grandchildren living together for more than 20 years.

When she learned that her husband was about to go on an expedition, most of Eva's organs had failed, and she could not take care of herself, so she needed to stay in an intensive care unit for a long time.

In order to be able to see her husband's body in person, Eva refuses to start the rebirth process immediately.

She said that after she died, she would live in the database, and when the new world was built, she would go directly from the database to Proxima Centauri B to meet David, and joked that she wanted David to taste the taste of taking care of her lover from a baby to an adult.

If all goes well with the original plan, in another decade or even less, the remaining personnel of the New World Engineering Command will decide to let Eva's soul go.

But according to the current situation, at this time, Eva may be begging for people in the Earth database for her rebirth.

On the other hand, with his own character, his soul has been thawed after a certain procedure, and after knowing that he has "disappeared" in Proxima B, he will definitely not agree to be reborn on Earth, but will ask to go to Proxima B again immediately.

In that case, would Eva strongly request to go to Proxima B again with her DNA sample and backup soul, and if so, the soul that she and Eva flew to Skyrim would definitely be deleted by Joseph as soon as they arrived on Proxima B.

No, if that's the case, Eva's genetic sample is in Joseph's hands, and the soul will also have a chance to fall into his hands.

It seems that he admires Eva very much, and has praised Eva's beauty when she was young in front of everyone more than once. In case of... My God! Don't let that happen.
