After the salamander was repulsed by the lord army, the remnants of the salamander fled back into the river.

Next, the scouts of the lord army began to look along the banks of the river for suitable places to build pontoon bridges, these salamanders and ghost snakes were like two creatures in the river and on land, if they looked like a group of reckless warriors on land, then they were like a group of assassins skilled in stealth in the river, their scales almost completely integrated with the river, and only when they released their ice arrows, they would only appear for a moment.

The pontoon bridges built by the lord's army several times were destroyed by these salamanders and ghost snakes.

At this time, Surdak finally realized what was the headache of these salamander ghost snakes, and they were the masters of the rivers in this area.

As long as they are not completely cleared, the lord army will not want to enter the hinterland of this plain.

The group of magicians led by Lance has been busy exploring the area around the Three Rivers Plain these days, and they have recorded the terrain and landforms they have seen in the magic crystal with a Surdak, Lance did not expect that Surdak would actually ask their magicians to record every mountain in detail.

These images were mapped in Surdak's barracks.

On this map, which was accurately imaged by the magicians, it is clear that there is a large canyon in the upper reaches of the river in the Three Rivers Plain.

According to Surdak's plan, if you want to enter the hinterland of the Three Rivers Plain, you must completely clean up the salamander ghost snake colony entrenched near the plain river.

In fact, on the first day of the lord's army in the Three Rivers Plain, they had a battle with the salamander and killed hundreds of salamanders, and these salamanders always cowered at the bottom of the river, no matter how they lured them. Confused and unwilling to come out again, although the lord army is not perfect, it becomes very difficult to clean up these salamanders and ghost snakes along the coast.

The lord army does not have Naga warriors, and it is impossible to fight the salamander ghost snake in the water.

After some consideration, Surdak decided to lead the lord army up the river and camp down a valley in front of the Grand Canyon, which was only separated by a mountain from the Grand Canyon, and after the lord army camped here, Surdak did not rush to arrange the battle mission, but let all the lord army rest in place.

In the last few days, he has only sent out some scout teams every day to explore the surrounding area, and at the same time hunt the demonic beasts lurking around.

Although the scout team made some gains every day, the lord army did not succeed in entering the Three Rivers Plain.

The merchant group with the army can buy some Warcraft materials every day, but the quantity is not very much, and even some merchants began to complain that tens of thousands of lord troops are waiting here, and the huge cost of eating and feeding horses every day is not something that the scout team can make up for hunting these Warcraft, and if the loot is not captured, the merchants will not have much income.

The adventuring group that followed behind the merchant group found that this was a rare opportunity, for this group of adventurers, the border building of the Three Rivers Plain was a paradise hunting ground, and the river was full of salamanders and ghost snakes.

Usually they come out in groups, but even if they do, the adventuring party will choose to walk around them because of the large number of them.

But now that they're all hiding at the bottom of the river, the party has some special means to hunt them down one by one.

More and more adventuring groups began to hunt salamanders and ghost snakes along this river, but the lord army did nothing in the past few days......

Two days later, the merchants suddenly found a large number of migrant workers gathered outside the camp, and these laborers were basically hired from the town of Plantos, and on the first day they arrived at the camp, they began to dig a branch river next to the river, and they braved the scorching sun to dig a drainage channel from the exit of the Grand Canyon to the north.

In this way, the water flowing down from the upstream can be diverted.

Although these migrant workers look a little black and thin in everything they do, they are very easy to manage.

As soon as the foreman assigns them the task, takes them with the tools, and they can get to work immediately.

While the soldiers of the lord army were still wondering what these migrant workers could do here, Surdak had already completed the survey of the path of the aqueduct.

Subsequently, the group of migrant workers and a group of ordinary soldiers began to dig the drainage canal at the same time.

The two-kilometre-long canal, which is not much to dig by hand, took only seven days to dig under Tula's leadership, and although it needs to be widened in many places, it can already divert water from the river to the valley on the other side.

In this way, the river is split in two at the outlet of the Grand Canyon.

Subsequently, Surdak asked the soldiers and migrant workers to put the stones dug out of the drainage canal into a large barbed wire fence, and one by one the barbed wire pockets wrapped all the stones into the original channel of the river, and it took only three days to completely cut off the river, and all the river water was led down the drainage channel into the next valley.

The water level of the downstream river channel drops little by little, gradually revealing the riverbed full of silt......

In this way, the salamander ghost snakes that were originally lurking at the bottom of the river were exposed to people's sight again, and they were still trying to hide in the soft silt under the riverbed, and when the silt on the riverbed was exposed to the scorching sun, the silt began to crack, and these salamander ghost snakes realized that the situation was not good, and they began to crawl out of the mud of the riverbed and run in all directions.

On the grass on the bank of the river, a row of bed crossbows had been set up, and what a group of archers had to do was to shoot the salamanders and ghost snakes that crawled out of the mud at the bottom of the river, and almost all of them came out of the mud, and then lost all their flexibility because their bodies were covered with silt, and they became the target of the bed crossbows on the riverbed.

Giant crossbow arrows shot out, quickly reaping the lives of the salamander ghost snake.

The other lords and adventuring groups standing on the shore realized ...... It turns out that the war with Warcraft can still be fought like this.

One by one, the salamander snake that died at the bottom of the river was brought up by the warriors and thrown onto the caravan's four-wheeled wagon with little to no treatment, and then some magic crystals could be harvested from the merchant.

Surdak didn't take the heads of these salamander ghost snakes this time, these heads were badly broken, and they were only some rudimentary sacrifices.

Once the salamander snake died, its whole body began to fester, and when the warriors came up with their corpses, they looked like slugs without any skin, and their bodies were covered in slime from sticky lakes.

Without the protection of the river, even if these salamander ghost snakes managed to escape into the meadow by the river, they could not escape the shooting of the members of the adventure group swarming behind them.

Suddenly, the garrison camp at the edge of the Grand Canyon was full of jubilation, and when the river was cut off, the lord's army quickly built some stone piers in the river and prepared to build several stone arch bridges here.

The merchant group with the army finally obtained a large number of cheap materials for the salamander ghost snake, as well as a large number of first-level demon cores.

In addition to the salamander ghost snake, the lord army also harvested some Gambis devilfish.

Immediately afterwards, Andrew led a cavalry regiment of 500 men across the dry river and into the plain......
