In this way, Chen Xu has more time to study and hunt freshwater creatures.

Then he began to walk towards the top of the river valley.

Due to the heavy rain, the ground has become unusually muddy, and the uphill slope is still uphill, and he is often prone to slipping.

So, when encountering such a difficult slope, he had to plunge the tip of his shoe into the dirt before each step, and then exert force.

Sure enough, this little method worked.

Two hours passed, around 12 noon Indonesian time.

Chen Xu climbed two hillsides all the way to a cliff waterfall more than ten meters high, and the river on the bank, although the width has decreased, but the depth is increasing, and the water flow is obviously much more turbulent than downstream.

"Hmm...... Whew......"

He came to the waterfall, took a few sips of water, then washed his face and looked around, "The water under the waterfall is the most turbulent part of the river, and few creatures generally choose to move here, because the impact of the water is too strong. ”

"So, we have to go up the cliff, and according to the environment we have walked through, first the stream, the cliff, the swamp, the river, and now, we have encountered the cliff, and when it comes together, it is a ladder terrain. ”

"I speculate that there should be larger rivers or lakes on the cliffs, and there are only three large rivers in Borneo, and there are only three in Indonesia, one running through the north and south, one in the east and one in the middle. ”

"Judging from where I was jumping, we should be approaching this river in central Borneo, which is the Balitto River, the third longest river in Borneo. ”

"The flow of the Ballito River is from the central mountains to the southern plains, and from this point it can be calculated that our current direction should be north!"

Chen Xu's words couldn't help but make the audience in the entire live broadcast room stunned.

Just relying on a small stream, a river, you can deduce so many things, what a solid knowledge of geography and spatial memory is required!

"Nima, this sense of direction is really awesome, and it is definitely a great god of running pictures!"

"Hand a cigarette to the big guy!"

"Mom asked me why I was kneeling and looking at my phone!"

"Master Xu, why don't you come and make up for my high school geography, this cute girl 36D~~~"

Chen Xu calculated for a moment, and drew a rough topographic map in his mind of the terrain he had walked on yesterday and morning.

When he came back to his senses, he happened to see the last barrage under the screen, choked, and almost didn't squirt out the water in his mouth.

"Ahem! You ...... It's so naughty, I'm a little green fresh streamer!"

Chen Xu coughed twice.

In fact, the reason why he knows so much is that on the one hand, it is the knowledge brought by the platinum skill Wilderness Peak, and on the other hand, it is for this mission, he checked a lot of relevant information in advance.

After resting for a while, he found a spot near the cliff with the smallest slope, combined with vines, and climbed it easily.

And the moment he stood on the cliff, the scene in front of him, as he had guessed before, was a river that was wider than downstream.

"It's supposed to be the Bartoli River!"

So, Chen Xu continued to walk along the river bank to the north.

No freshwater creature would be stupid enough to move near a waterfall, so he had to go deeper into the river.

After walking for less than half an hour, the river suddenly had two inflection points.

There is a bifurcation in the upper reaches of the river, but in fact, it is the same for either way, and they will eventually converge anyway, because there is only one source.

Chen Xu squinted, thought for a moment, and pointed to one of the ones with a slightly thinner width and a relatively slow water current, "Let's go this way, large freshwater creatures like rivers or lakes with wide waters, large depths, and relatively quiet waters." ”

It turned out to be just like he said.

After walking for more than ten minutes, the river forked and really led him into a huge lake!

The lake in front of him was bigger than any lake Chen Xu had seen before, and it was no exaggeration to say that he couldn't see the edge at a glance.

The entire body of water, as far as the eye can see, is full of turbid yellow water, except for the lake, and even the jungle on both sides has been submerged into a swamp.

"Do you see the tall gray trees on either side of the lake?"

Chen Xu stretched out his hand and pointed ahead as he spoke, "These are eucalyptus, only Indonesia, New Guinea and Australia are distributed in the world, and they are tropical evergreen trees. ”

"Eucalyptus has a characteristic, that is, it has a strong water absorption, a 15-meter-high eucalyptus tree, an average of 1,000 pounds of water a day, very terrible, so, to support so many eucalyptus trees to survive, and can also develop swamps and lakes so large, the depth of this water area is estimated to be quite terrifying!"

"And this wide deep water area is where large freshwater creatures like to stay, and we're here today to start the capture program!"

After speaking, Chen Xu immediately pulled out the mountain opening knife, bypassed the swamp next to him, and walked into the depths of the jungle.

"It's too physically demanding to just swim around a lake of this size, so we had to build a simple raft to get around. ”

"The best material for making rafts is balsa wood, but unfortunately it is mainly distributed in the tropical regions of the Americas, and very little in Indonesia, and most of them are transplanted later." ”

"Borneo is a pristine tropical rainforest, which has not been cultivated by the government, and it is estimated that it is difficult for balsa trees to grow, and even if there are, at most there are only a few trees, so we have to target the genus Kapok. ”

In the process of saying this, Chen Xu came to the side of an arbor with a thigh thickness and a height of more than ten meters.

What makes the audience feel strange is that the branches and leaves of this tree bear a lot of green and yellow skin and large fruits with spikes.

Looks...... Some like durian!

"That's right, everyone is right, this is wild durian, there are many types of kapokaceae, fruit kapok, light kapok, etc., durian is also one of them, it is a plant native to Indonesia, and it is widely distributed. ”

"However, the durians we eat every day are all varieties that have been improved by botanists, and the real pure wild durian actually tastes average, just like wild plantains, and there is no way to eat it at all. ”

"Let's not care if it can be eaten or not, durian belongs to the kapok family, and the density of the trunk is very low, although it is not as exaggerated as balsa wood, but there is no problem in making a simple raft!"

As he spoke, Chen Xu picked up the mountain knife and slashed towards the durian tree.

Not to mention, the trees of this ceibaceae family are really soft, which is in strong contrast to the previous cycads.

This knife came down and cut directly into it three or four centimeters deep.

It only took a few minutes for Chen Xu to hear a muffled sound of "bang" on a large tree.

This wild durian tree was cut down.
