The Normen is a small tribe with 300 trolls, and the total number of available soldiers is no more than one hundred and five.

When Bladefang arrived with a formation of 325 trolls, he simply flexed his muscles and reclaimed them without surprise.

After that, he sent some hunters to hunt with the local trolls, and hurried to gather the food they needed.

As for the usual tasks such as counting the 'population' and sorting out the inheritance, he was given to Meiya, who had already been 'coaxed' on the night of his arrival.

And he himself, holding on to his somewhat sore waist, dragged the warriors to the wood.

~~~~~~~

Originally, Blade Tooth was a canoe that I wanted to try first, and it felt like it would be relatively easier.

But after experimentation, it turned out that it really just 'feels' simpler.

First of all, trolls are too big, and it is difficult to find the right wood;

Secondly, hollowing out the center of the wood to create a space that can accommodate the trolls is also a big job.

After a few attempts, he decisively abandoned the unrealistic idea and focused on the 'raft'.

First, the hunters were arranged to cut down the trunks of various trees and put them into the water one by one, and the specific gravity between the different materials and the water was compared.

After several comparisons, one of them with the strongest buoyancy was singled out, and 'manpower' began to be arranged for 'large-scale' mining.

During the mining period, Bladefang himself was not idle, using magic to start making vines for binding.

Since the vines to be used this time did not need to be transformed to the extent that they restrained the moose leader in the first place, the overall manufacturing efficiency was not bad, and it only took half a day to get hundreds of thumb-thick and more than a meter long.

Bladetooth felt that it was almost enough, so he returned to the Nomen and began to plant the few refrigerator tree species that were already few.

Later, they turned to help Meiya organize their legacy.

Almost a day passed, and the hunters who had been assigned to cut wood, with the help of the army's magic apprentices, finally picked what seemed to be enough trunks.

When the time came for night, Blade Tooth arranged for all the staff to take sleep rotations;

Whether it is a tooth troll or a Nomen troll, he always maintains a third of his labor and can build rafts under his direction.

said that it was a 'guide', but in fact, he himself was a 'person' in two lives, and this was the first time he got started, so he stumbled and encountered a lot of problems.

The weight of a troll in the prime of life is between 800-900 kilograms, and the weight of the weapons he carries with him can be nearly 100 kilograms.

In this way, the load capacity of the raft must be at least one ton or more to be insured.

The weight and volume of the wood, the load and buoyancy, and how much flat space it can provide..... and so on, under the entanglement of several factors, it took several failures before finally succeeding.

The tentatively shaped raft is a horizontal and vertical double-layer overlapping structure, each raft ensures sufficient buoyancy while allowing the troll to lie and lie down while leaving a certain amount of baggage space.

After finalization, it is time for stability testing between marches.

Two lengths of unilinear vines were prepared, one connected to the raft to the shore, and the other tied to the waist of the troll acting as an experimenter.

The chosen troll, who was quite frightened at this time, did not enter in front of the raft, but he saw that the seniors who had climbed down before were quite miserable....

Not far behind him, several trolls who were in charge of leading the middle of the vine kept laughing at the trembling-looking companion, constantly urging him to hurry up.

Blade Fang was also a little helpless about this, and he had just discovered that trolls in the prime of life generally had a physique that sank when they entered the water.

Before, the water depth of the Black River was not enough, and they all stepped on the bottom of the river to cross it, so they did not find this in time;

When taking a boiling bath at home, the depth of the bathtub is even more unlikely to make him aware of this problem in time.

But the White River is different, the depth of the water on the banks alone is already more than the height of the trolls, and except for a few sections, it is almost impossible to step on the bottom of the river.

Fortunately, he was cautious enough to tie vines to the experimenter's body at the beginning, otherwise it would be difficult for those people to be rescued just now.

'The only attrition on the expedition actually came from drowning?' If such news had been passed on to future generations, they would probably have died of laughter.

Actually, Bladetooth had the intention to do this experiment himself;

But after thinking about it, they felt that this was a test that they had to go through, otherwise how could they use the river water to march quickly in the future?

So, he only gave verbal encouragement.

Fortunately, trolls are social animals with a strong sense of shame, and they don't lack courage....

The experimenter, after all, could not resist the jokes of his companions, closed his eyes, and jumped onto the raft, which had a certain gap from the riverbank.

Seeing this, the partners stopped laughing, and after seeing him 'standing' steadily, holding on to the gap between the woods, they directly let go of the vines in their hands.

The raft, which had lost its restraints, began to move slowly diagonally towards the center of the river, following the current.

The vines that had been piled up in the middle were now also stretched out over the river in circles under the traction of the raft.

Gradually, the raft moved faster and faster, and Bladetooth was keenly aware that its speed had even exceeded the speed of the river itself.

This surprised and pleasantly surprised him, and he thought that he would be able to be on a par with the water at most, but he didn't expect to have this kind of gain.

While he was happy, he also wondered how this broken raft, which had no sails or oars, could exceed the speed of the river.

At this moment, two slightly elastic voices with 'tension' in my ears came.

When I turned my head, I saw that the raft had flowed to the limit length of the vines, and the other end was tied to two vines from the same tree, which were now tense in the air and constantly shaking.

Blade Fang glanced at the raft from a distance, and found that it was floating there well, and there was no sign of capsizing or sinking.

The hunter who waited for the vine pulled it back and let it go again, and after repeating this several times, the raft was still floating steadily in the water.

"Well, pull it back, that's pretty much it."

After instructing the experiment to be over, he said to the apprentices on the side,

"That's it for now, it's time to start production; As for the future improvements, I will leave it to you younger generations..... In addition, the materials are still a little excessive, and tomorrow you will have to lead the hunters back to cut down more, and I will also prepare some more vines here..."

The witch medicine disciples nodded yes when they heard this, and immediately began to guide the rest of the trolls in the construction of the raft based on the results just now.

Moments later, the raft from the previous experiment finally came to shore.

The experimenter, who had a 'I'm back alive' expression on his face, began to grow smug as soon as he landed on the shore, and he stared at his companions who had laughed at him before, and let out an arrogant laugh.

"Come on, let's experiment a few more times, and you will work harder."

Blade's words made his face change again, and he jumped back into the raft with a bitter face.

This time, however, the experimenter had clearly overcome his fears and was at least able to sit with his ass down.

Blade Tooth nodded in relief, revealing a 'teachable' expression.

It's not that he's deliberately tossing the troll, but he really wants to figure out why the raft is faster than water, and this experimenter is the biggest variable on the raft before, so it's not good to replace it in the first place.

Of course, he asked himself if he was not capable of explaining the problem at the level of principle;

Therefore, we only plan to start with the 'phenomenon' and find out the laws between them through repeated experiments, so as to make better use of the river.

With this in mind, in the following experiments, the blade tooth successively reset the variables several times by changing the 'direction of water entry'.

I want to find out the most direct reason that affects the speed of the raft.

Fortunately, the hard work paid off, and he finally discovered that the speed of the raft seemed to be proportional to the load..... After confirming this, the direction of the follow-up experiment was finally clear.

After repeated trials, the balance between safety and speed was gradually figured out, and the weight of each raft was re-planned.

..........

A few more days passed, food, rafts, and other things were ready, and the trolls were about to embark on their return journey.
