Defeating the werewolf clan of the Iron and Wood Collar, the return journey was smooth, and there were no powerful lords in Baili Valley Road, all of them were praying that Lin Yi would not come to the door, so naturally they did not dare to come and tease the tiger's whiskers.

When I returned to Longmen City, it also took a day, and although this line had a good harvest, it also suffered a lot of losses.

Thirty-three greedy wolf commanders, fifteen greedy wolf chiefs, nine white tiger captains, three white tiger chiefs, six hundred and ten greedy wolf cavalry, eighty white tiger cavalry.

When he was on the way, Lin Yi had already found an opportunity to complete the summons, returned to Longgu City, placed the war horses, and held a mourning ceremony in Longgu City that night.

Along the way, sitting on a county, with tens of thousands of soldiers, more than 1,000 soldiers killed unconsciously, the war is a meat grinder.

The Kot Collar and the Iron Wood Collar are just a county, and the opponents will only get stronger and stronger in the future, and the limitations of relying on cavalry to charge the formation in a large war are getting bigger and bigger.

Lin Yi is just a rookie to lead troops to fight, but he has watched a lot of TV series, the infantry corps fights head-on, the archers are consumed, and the cavalry is killed on both wings.

The cavalry fought a blitzkrieg, relying solely on cavalry to fight, and it was true that the field battle was invincible, and the siege of cities and land was insufficient.

On this trip, Lin Yi can also see that he is not a material to lead troops to fight, and he will still make a big strategic direction in the future, and leave the rest to his generals.

"Lord, in the past two days, a small group of ogres have appeared on the opposite bank of Black Mountain City and Great Wilderness City, I guess they are going to make a move against Longgu County, but it is not clear whether it is the ogre who stayed in Sifang County, or the deployment of the ogre emperor."

At the end of the mourning ceremony, Li Ru came to report the situation to Lin Yi.

"The main force of the ogre is attacking Saint Fort County, Jiuyuan County, and Changfeng County, and it should not be able to deal with Valan Province in a short time, and it is likely that the ogre who stayed in Sifang County wants to clean up the surrounding area." Lin Yi pondered for a moment and said.

"The interior of the orc clan is really chaotic, the Black Luo Province is in trouble, and the surrounding provinces are actually sitting idly by, and when the ogre gets a firm foothold, they may not be spared." Li Ru shook his head and said.

"It's none of my business, hang high, those big lords, who haven't thought carefully about annexing the surrounding areas, maybe they are doing it on purpose, wanting to wait until the Black Luo Province is destroyed by the ogre, and then send troops to repel the ogre to swallow the territory of the Black Luo Province."

The orc clan doesn't look very smart, but one has more eyes than the other, look at Taylor, and then look at Norn, in Lin Yi's words, they are all old yin goods.

The disaster in the province of Heiluo is a good thing, and it is a good thing that the surrounding lords do not have black hands, of course, the strength of the ogre makes it impossible for them to intervene.

"The lord still needs to take precautions, these ogres are definitely premeditated, this time the disaster may be more than just that simple, the ogre clan has endured for so long, there may be bigger hole cards." Li Ru guessed.

If the ogre really attacks Longgu County, it will be really troublesome, first of all, there is no favorable battlefield in Longgu County, and the only line of defense is a barren river, but the barren river can't stop the ogre's attack.

And Lin Yi couldn't take the initiative to attack, on the other side of the barren river was the Great Forest of the Eastern Wilderness, and the ogres were all infantry, and Lin Yi's cavalry couldn't give full play to their advantages.

When the ogre enters Longgu County, there are more directions to attack, Lin Yi can't be rescued if he wants to, there is a delay in information transmission, as a passive defender, this time difference will make Lin Yi suffer a big loss.

Even if you can defend the city, the fields outside the city are bound to be affected, and God knows how long this group of ogres will have to make trouble.

After thinking about it carefully, Lin Yi decided to build a city wall between the Great Wilderness City and the Black Rock City, so that if the ogre wanted to enter Longgu County, he could only go through the Black Rock City or the Great Wilderness City.

However, this project is extremely huge, the Great Wilderness City is one hundred and thirty miles away from the Black Rock City, and the circumference of the high-level city wall is eight thousand meters, which is equivalent to building eight high-level city walls between the Great Wilderness City and the Black Stone City.

But once this wall is built, then Longgu County can be described as impregnable, and there is no longer any fear of foreign invasion.

Lin Yi wanted to turn Longgu County into a granary, the barren river basin could go ashore anywhere, hiding dangers, and sooner or later it would be deliberately used, and it was impossible for Lin Yi to send people to patrol the coast 24 hours a day.

This wall still has to be built.

The next day, Lin Yi immediately mobilized all the labor force in the entire Longgu County to collect stones and prepare to build the Barren River Defense Line.

It just so happened that the Outer Valley City of the Matou people had not been built, so Lin Yi directly relocated the location between the Great Wilderness City and the Black Mountain City, so that a high-level city wall could be omitted.

The name of the city can no longer be called Waigu City, but Desert River City, which will be used as a naval army camp in the future, and there is a naval army camp in Great Wilderness City and Black Mountain City, which is very inconvenient, and it is appropriate to move the naval army camp between the two places.

The ogres were ravaging the province of Heiluo, and the orcs in Longgu County already knew that the Barren River defense line was built to defend against the attack of the ogres, and these orcs did not complain much.

With only the stone materials in Longgu County, eight high-level cities and one medium-level city can be built, and it is definitely impossible to build eight high-level city walls.

Lin Yi dispatched all his soldiers, including the orc soldiers, to cross the barren river and collect stones from the depths of the Eastern Wilderness Forest.

With a labor force of 70,000, an average of two days can scrape together the stones needed to build a high-level city wall, and Lin Yi first expanded the Great Wilderness City into a high-level city.

The first high-level city wall is connected to the west wall of the Great Wilderness City, and the second high-level city wall is connected to the west wall of the Great Wilderness City.

The third high city and the fourth high city wall extend to both sides.

In order to facilitate the transportation of stones, several high-level city walls in the back waited until all the stones were gathered and built and closed at one time.

Lin Yi's big movement also attracted the attention of the ogres of Sifang County, and from time to time, ogres came down by boat to investigate the situation.

However, they were all blocked by Ling Tong's team, and Ling Tong also personally led the team to explore the coast of Sifang County, and this investigation brought back bad news to Lin Yi.

The ogres of the Quartet are building ships in large numbers!

On the side of the Great Forest of the Eastern Wilderness, a shipyard is beginning to take shape, and a large number of orcs are processing and building ships.

These ogres are really tired, if they are only to capture Heiluo Province, there is no need to build a large number of ships, but Lin Yi can't guess whether these ogres want to carry them on their backs or go south.

If it is to plot against Valan Province, there is no need to take the route of the Barren River and plot against Zilan Province, these ogres are not so crazy, the Golden Lion Clan is one of the two strongest royal families of the Orc Clan.

Thinking about it, the goal of these ogres should be to go north, and the Black Dragon Province will go north, and if you take the land route, you will have to collide with the Orc royal family, and if you take the water route, you can attack the other two provinces that do not have a royal family.
