Because it is surrounded by water on three sides, there is no need to worry too much after setting the fire, Song Xuan only asked a few people to make occasional inspections, and after a night, the fire has basically spread to the entire forest, even across the river, you can feel the high temperature blowing with the wind.

In addition to burning the trees on the ground, this fire also made the temperature around the tribe much higher, at least not as cold as before, but it made everyone more comfortable.

The materials used to build the bridge have already been prepared, and they have dried out after such a long time, and now they can be used directly when they are moved over, and Song Xuan also took the time to burn both sides of the wood with fire with Shi Ban and a few people, although it is not particularly smooth, but whether it is to build a bridge or walk on it, it will be a lot more convenient.

Since it is only for people to pass, it does not need to be too wide, Song Xuan tentatively set it as four logs, so that no matter how you make the bridge deck, it can be about two meters wide, even if it is a cow, it can easily pass, and at the same time, it will not look particularly crowded.

There is no great difficulty in erecting a wooden bridge, the only thing that is more troublesome is the wooden stake in the middle, which is similar to the fence for fish farming, but the fence is made of bamboo, and this one is replaced by a thicker wood.

Because it takes two pieces of wood to put together to make a bridge, the wooden piles in the middle have to be made in two rows, after determining the length, Song Xuan asked Shi Meng to row the boat to the middle of the river, everything is difficult at the beginning, and it is also difficult to nail the wooden stakes into the water, although there is no need to enter the water on the boat, but it is not easy to maintain the stability of the canoe.

Several bamboos were inserted into the river, and the three of them were held on to keep the boat from flowing down the river.

The location for building the bridge was also chosen by Song Xuan a long time ago, and after arriving at the designated place, Shi Meng and the others also knew that they could not delay, as long as the first pillar was done, it would be much more convenient in the back, at least the boat would not be so easy to float away.

So he tried to nail the pillar into the mud, but the embarrassing thing was that Shi Meng just held the pillar and inserted it into the water, and as soon as he let go, the wood floated on the surface of the water, and then he looked at Song Xuan a little innocently:

"Divine Messenger~"

was as aggrieved as a little daughter-in-law, but it startled Song Xuan with goosebumps.

Since the wood used to make the bridge deck is relatively thick, this pile naturally cannot be too thin, and Song Xuan chose wood that is thirty or forty centimeters thick.

Even at this time, the depth of the water in the middle of the river was nearly two meters, and it was not easy to insert wood into the mud on a rickety boat, and Shi Meng tried several times in succession without success.

In a fit of anger, Shi Meng ripped off the animal skin on his upper body, and Song Xuan watched Shi Meng from the shore and wanted to jump into the water, but he also hurriedly stopped:

"Don't jump! Wait for me a while."

Then he said to Shui Yun and Shi Ban beside him:

"Shuiyun, row another boat!"

"Shi Ban, go find some big rocks, the kind that one person can hold."

He ran back to the tribe and got some hides.

These things were not difficult to prepare, and soon Song Xuan came to the middle of the river with a small boat.

When Shi Meng saw Song Xuan coming, he said with some grievances:

"Divine envoy, this can't be pressed on the ship~"

After the two boats were connected, Song Xuan complained:

"Stupid~"

"The river is so cold, you jump down too?"

Although Shi Meng has rough skin and thick flesh, even if jumping into the water will not have a big impact on the body, it is still uncomfortable after all, and it is better not to go into the water as much as possible.

Then Song Xuan took the animal skin and grabbed the stone found by Shi Ban, and then tied the stone to the lower part of the pillar:

"Try again now!"

Sure enough, after adding the counterweight, the pillar was lowered again, and it was much easier to go, and Shi Meng could easily hold it down alone, seeing that the others were still amazed, Song Xuan scolded with a smile:

"What are you still doing in a daze, hurry up and smash a stone into it!"

"Oh...... Oooh~"

Only then did a few people on the side react, and they picked up the stone in a panic, raised it above their heads and began to smash the wood.

This stake is four or five meters long, and even if the bottom has been sharpened, Shi Meng pressed it down vigorously, and the surface of the water was more than two meters above the water at this time.

In order to ensure that the bridge can be used most of the time, it must be at least about one meter away from the water at this time, and maintain this height to build the bridge directly from both banks.

But in this way, it is not so easy to set the wood into the river, everyone is not tall, even if the stone is overhead, you can see the top, even if Shi Yong jumps up, it is a little choked, and jumping on the canoe, directly makes the whole boat shake.

Seeing this, Song Xuan had no choice but to make a move, after all, he was tall in the tribe, and his arms were relatively long, and after lifting the stone, there could still be a certain gap between him and the top of the wood.

Although it is not easy to smash, but when it is smashed down, the wood is slowly sinking, and soon it will be about the same height as everyone.

Coupled with what Shi Meng pressed into before, the wood is now about sixty or seventy centimeters in the mud, although the resistance is getting bigger and bigger, but this depth is definitely not enough, and it has to be deeper to make the pillar more stable.

A few people snorted and smashed for a while, and finally it was impossible to see the obvious sinking, at this time the pile exposed to the water is waist-length height, basically about the same height as the riverbank, the pillar is a little higher, it is okay, the riverbank on both sides can also pad a pad, but if the pillar is short, it will be more troublesome, not only closer to the water surface, if you want to erect it, you can only dig the riverbank.

With this first pillar, it was much more convenient to have it behind it, at least the boat could be tethered directly to it, and the degree of shaking was much less than before.

In order to test its firmness, Song Xuan asked Shi Meng and them to tie the boat directly to the wooden stake, and the other struts were all pulled up, even so, the wooden stake did not have the slightest tilt, and stood firmly in the river.

In order not to affect the wooden stake behind, Song Xuan remembered that it was also a slipknot when tying the rope, and at this time, the stone could be pulled out of the water with a slight pull.

Then he did the same, and by noon the first row of pillars had been firmly fixed in the middle of the river, five or six meters from the bank on the tribe's side.

However, because the depth of the nail is not easy to control, the height of the stake out of the water is not the same, but fortunately, it has been reached, and the limit of manpower can be set into it, and it is good to level it later.

After eating, he continued to work, and it was started on both sides at the same time, Shi Ban led people to repair a few piles, and Shi Meng was still responsible for continuing to nail the wooden piles.

In order to keep it stable, the two rows of wooden stakes in the middle are not far apart, only less than two meters, which is about the width of two canoes, so that if you get it right, the wood on each side only needs to be exposed about a meter in the middle.

In this way, even if he walked to the middle with the goods, he would not press the bridge up, and at the same time, Song Xuan took Shui Yun to clean up the two sides of the river.

The wood has also been pulled to the shore, and it is only necessary to wait for the pillars to be nailed before it can start to be erected, and with the previous experience, the speed can be faster.

After the stone class leveled the pillar, Song Xuan began to erect the wood, the wood that is more than half a meter thick and seven or eight meters long is not light, but it is easy to get on the shore, and a few people can easily lift it up with a rope.

It's a little more troublesome in the water, but fortunately, there are boats in the tribe now, but it's more difficult to put the wood in the middle of the boat and then think about standing on both sides, so Song Xuan asked people to row two more boats.

With their superb skills, Shui Yun put the wood in the middle of the two canoes, and several people on each side were responsible for lifting it, and the people on the shore and the people on the boat cooperated, shouting the trumpet, and slowly pushing the wood to the middle.

"One-two, hey"

Song Xuan was in charge of observing and directing from the side, and when he saw that he had reached the wooden stake, he reminded:

"Slow, slow!"

After the front end was erected on top of the wooden stake, it was much easier, and it was quickly adjusted to the right position, Song Xuan had already marked the length of both sides on the wood, so after reaching the trace, he stopped.

The wood used to build the bridge has been trimmed, and the bridge deck and the part that is built on the pillars are relatively flat, and there is no shaking at all when it is erected.

"Go up and try ......"

Build the first log erection, everyone is not a little eager to try, even if it is a wooden bridge deck, there is a small half meter wide, used to pass people, it is not a problem.

However, seeing that Shi Yu rushed up all of a sudden, Song Xuan still opened his mouth to remind:

"Be careful......

It's been as smooth as possible, but it's definitely not going to fit perfectly.

But fortunately, Shi Yu was still very stable after he went up, twisting his hips left and right and said:

"Oracle, look ......"

"Steady!"

Seeing that Shi Yu won the first place, the others were not far behind, and they followed one after another, and for a while, the wood was crowded with people.

"Alas, why are they all crowded up, let me go down first......"

"Go down? You jump, hahahaha! ”

Anyway, I scared Shi Yu a little.

…………

Seeing that everyone was having a good time, Song Xuan waited for a while before calling them down.

After the first log is erected, there is no need for Shui Yun to support them in the water, just pull it directly on the bridge, at most wait for the position, and let Shui Yun and them help adjust it slightly.

The second row of piles has not been nailed yet, and the bridge deck on Teng Snake's side has been erected, although it is not perfect, and the surface is not very smooth, but it is not a problem to pass through.

"Fierce, you guys hurry up"

Seeing the excitement is not a big deal, a group of people squatted on the bridge in the middle and began to talk about the wind and coolness.

There was no need for them to say something to stimulate them, Shi Meng and the others saw that the bridge had already been set up on this side, and they also unconsciously accelerated the movements in their hands.
