In the distance, on the boundless wasteland overgrown with weeds and shrubs, warriors in black armor were bent over, waving their arms, and busy with their swords hanging from their waists, and replacing them with shovels or pickaxes in their hands, digging in a straight line, taking shape along a wide river in the east.

Listening to the shouts of the soldiers, Alan nodded with satisfaction, this time in order to dig this river - Allen named it the Huijin River, he specially dispatched the newly formed Heilan Army, a full four thousand five hundred and thirty soldiers, digging day after day, now the length of the river has crossed the hill, is spreading towards the mining area, if it is at this progress, it is estimated that it will not take two days to complete.

In the hot weather, Abyss wore a black cloak and rode a war horse to Alan's side.

"Lord Viscount! Captain Antonio and Captain Kant have launched an attack on the nezumi camp, with Lord Bahamut assisting you!

"Hmm!"

Alan nodded, this order was given by Alan last night, through the detection of the flying cavalry, Alan found that the number of nezumi warriors in the rat camp has not increased at all these days, it seems that the rat tribe did not send troops to support the camp, and it can be directly exterminated.

"What's the news from Giant Wood City?"

"My lord, according to the news reported by the shadows lurking in Giant Wood City, the Red Rat Tribe and Giant Wood City stopped after two fierce battles at the border, and now the two sides have formed a confrontation situation!"

"Oh, so the city is unguarded now?"

After hearing this, Allen's eyes lit up.

"According to the subordinates, the soldiers who stayed in Giant Wood City this time should be about a thousand, there is only one corps in Giant Wood City, the Giant Wood Corps, and the number of soldiers is about five thousand, this time the city lord of Giant Wood City brought about four thousand soldiers of the Giant Wood Corps to the border to block the army of the Red Mouse Clan. Abyss said.

Hearing Abys's answer, Alan knew that this was the best chance to take Giant Wood City, and he decided to wait for Antonio and them to return, and then immediately let them go west, and take Giant Wood City before the city lord of Giant Wood City returned with his troops.

——

At this time, to the south of the Rat Blood Fortress, inside the Rat Man camp.

The scene was extremely chaotic, the outer wall of the camp built by the nezumi had been torn down, and the main force had been wiped out in an attack, and now only a few nezumi were left to flee frantically near the camp, screams of fear and bloody screams spread in all directions, and the warriors of the two major knights were hunting down these fleeing nezumi.

"Poof!"

A blue light flashed, and Antonio held the ice sword in his hand and beheaded a high-ranking nezumi who wanted to escape at an astonishing speed, and when he saw Antonio's thoughts, the ice on the sword dissipated, and the blood was also returned to the sword into the sheath.

A few minutes later.

"Captain, all the fleeing nezumi have been shot!" said one of the captains as he approached Antonio.

"Inform Captain Kant and start cleaning up the battlefield!" Antonio nodded.

"Yes!"

......

After inspecting the progress of digging the river, Alan returned to Heilan City, and before the unification of Heilan Island, Alan will always live in Heilan City, after all, Heilan City is much closer to the Nezumi Tribe and Giant Wood City than Giant Rat City.

After entering the Carat family's mansion, Alan took out the map in the Void Bead again, placed it on the table, and looked at it carefully.

At present, the camp of the three nezumi tribes should have been breached, and it is effortless to take the current Jumu City with Allen's strength, which means that before Allen unifies Heilan Island, there are only four nezumi tribes left to exterminate.

Excluding the Red Rat Clan, the other three Rat Clans, counting the army in the camp, have been wiped out by Allen with 17,000 Rat Warriors, and in terms of the size of the three Rat Clans combined, it is definitely a big loss of vitality, plus a Red Rat Clan that has been consumed by Giant Wood City, Alan has absolute confidence to take them.

Of course, this is considered from the aspect of strength, but from the practical aspect, it is not easy to take them down, the Red Rat Clan and the Golden Rat Clan are a little easier, their nests are one on a vein, the other is near the fire pit, both above the ground.

According to the description of the flying cavalry, the vein was located on a plain, the nest of the Golden Rat was made of metal ore, and the Red Rat built the nest near a large fire pit, which was larger than a basketball court, and there was hot magma in it, and the flames above it were high, and this fire pit also surprised Allen, it was not like a volcano, but like a magma pool.

These two nests are very easy to break, it is rare to be the nest of the gray squirrel tribe and the black mouse tribe, the nest of the gray squirrel tribe is built underground, once the gray squirrel clan hides in the ground and does not come out, Allen's army has no way to take them.

The nest of the Black Rat is also difficult to break, the territory of the Black Rat is in the southernmost part of Heilan Island, there is a huge lake here, it can be said that the territory of the Black Rat is this lake and a small amount of land around it, Alan named this lake Black Rat Lake.

The black rat clan depends on this black rat lake to survive and reproduce, their water is excellent, no less than some fish, they live by catching fish in the black rat lake, as for their nest is built on an island in the middle of the lake, this island is in the center of the black rat lake, except for taking boats and flying, it is difficult for humans to land on the black rat island, this is still Alan without considering the black rat clan to block the situation.

Allen's top priority is to study how to exterminate the gray squirrel clan and the black rat clan, and the advantages of the two clans are not something that Allen's current strength can easily negate.

Even if Eren was now an elemental knight, it would be impossible for him to wipe out the entire Grey Squirrel clan underground on the ground.

The same is true for the black rat clan, even if Alan takes advantage of his unpreparedness and attacks the black rat island overnight, attacking the rat den with super means, although it can destroy the black rat nest and kill a large number of black rat people, there will definitely be a group of black rat people who burrow into the black rat lake and escape Allen's pursuit.

Unless Allen's strength reaches the legendary realm of being able to overturn the sea and the earth, it will be difficult to solve these two rat clans perfectly with brute force.

The territory of the five rat clans is perfectly displayed on the map, the territory of the blue rat clan is in the east of Heilan Island, the red rat clan is in the west, the black rat clan is in the south, and the gray clan and the golden rat clan are in the middle of the three clans and the human race.

At present, Alan plans to exterminate the red rat clan and the golden rat clan close to it first, and the persimmon picks up the soft pinch, first destroys the two easy ones, and then deals with the tricky ones.
