Because there is no guarantee that relying on the existing defense facilities in Southwest City will definitely be able to block the opponent's attack.

Therefore, on the way back to the southwest city, Lei Laohu issued an order to Leonardo, the hero who stayed in the city, to recruit all the recruitable troops in the city and build a large number of defense facilities, and even issued an order to Smith stationed in the southeast city, ordering him to give up the garrison of the southeast city and rush to the southwest city to support.

As for why Lei Lao Hu is sure that there is an enemy chasing after him in the rear, and there must be a hero, there are two reasons.

The first point is what he saw outside the Northwest City and made a judgment.

He speculated that there were two possibilities for the situation in the Northwest City; One is that the lord of the northwest city is hot-headed, rushes out to fight with the enemy and is killed by the other party, and the city is also taken by the enemy, after which the enemy lays a trap and waits for the troops of other cities to come to help.

Another possibility is that the city lord of the Northwest City betrayed the light camp and took refuge in the dark camp, such a thing is not uncommon, that is, didn't the commander of Heaven also betray Heaven and become a demon king of Hell? Not to mention the warlike barbarians, who are willing to do anything as long as there is an opportunity to war.

And through Lei Laohu's observation, the Northwest City is too clean, and there is no trace of the battle, no matter how hard you try to clean it up, there will always be a trace of it, but the Northwest City has not left a trace of the battle, so he thinks that the possibility of the second situation is relatively high.

But in either case, the enemy must have at least one hero, because with the intelligence of the Harpy Witch, Thunder Tiger doesn't believe that it can do such a delicate thing.

The second point was based on Lei Laohu's guess about the purple-level advanced task, which was also thanks to that ambush in the forest, otherwise he would not have thought of this.

He had already affirmed that the Purple Level Advanced Quest was for the purpose of cultivating players, and it was not intended to embarrass players.

Then this advanced mission will allow players to quickly experience a simplified battle process from city construction to rescue battles, to city defense battles, and finally siege battles.

Lei Laohu's construction of Southwest City, that is, the process of city construction, the task is to teach players how to build a city, and experience the fun of building a city.

The rescue battle, which can also be said to be a field battle, is the aid of Thunder Tiger to the southeast city, mainly to teach players how to command a large-scale battle in the wild, and by the way, experience the battle between more than 1 brigade of troops.

As for the battle to defend the city, it should be the battle in the Northeast City, it should be said that the terrain of the Northeast City looks similar to the Southeast City, in fact, the rescue of the barbarian hero should be given priority, after all, there are not too many enemies near the barbarian hero, and it is still very easy to rescue him, but Lei Laohu didn't expect these at that time, plus the advantage of his own strength was there, so he took the way of attacking.

For the battle to defend the city, Lei Laohu guessed that it should be in the southwest city, otherwise the southwest city is only used as a logistics base, which is obviously not very reasonable, so it is also very likely that the enemy will press the border on a large scale and carry out a large-scale battle to defend the city.

Of course, the siege battle should be the final decisive battle, attacking the dungeon city, and what Lei Laohu can't figure out is the northwest city, is there still a siege war there?

Based on these two reasons, Lei Lao Hu guessed that the enemy must be following behind him, and the number of troops was quite large, after all, the defender not only has a towering city wall, but also the defensive buildings of the city, and the existence of arrow towers, which makes the advantage of the defender very obvious.

Moreover, the troops of the defending side can be unlimited, and the defending side does not limit the number of troops it leads, as long as there are enough troops, they can participate in the defense of the city.

So Lei Laohu guessed that the number of enemies was many, very many.

Since the enemy has a lot of troops, let's consume them, use these field units that have been turned into mummies to consume the enemy's strength, and by the way, you can also delay the enemy's marching speed and give yourself more time to prepare.

In this way, regardless of the loss, it took a full day of dungeon time to enter the scope of the Southwest City.

Thunder Tiger's sharpshooter force was also lost at the moment before entering the southwest city, and only 10 mummies remained in his army, except for the 42 royal griffins.

As soon as he stepped into the city of Southwest City, Lei Laohu also breathed a sigh of relief.

Before he had time to take a breath, he strode into the council hall of the southwest city and began to take over the construction of the entire city and arrange the defense.

Yes, the current Southwest City still only has the lowest level of the council hall, and it is still only a level 1 city, which makes Lei Lao Hu feel helpless about Leonardo's internal affairs ability, ordinary heroes are ordinary heroes after all, and they are really too far behind the work they are not good at compared to famous heroes, too far, such heroes are only worthy of being cannon fodder.

Shaking his head slightly, Lei Laohu checked the available troops in the city through the control panel of the council hall.

1 brigade of spearmen, 4 squadrons of halberders, 3 squadrons of archers, 2 squadrons of marksmen, 42 royal griffins, 10 mummies, and 4 heroes.

After a little thought, Lei Laohu directly assigned the work of these heroes.

"Ken Lohag, you lead 2 squads, 24 royal griffons quickly leave the southwest city, find a place to hide near the city, everything about this unit, I will do it cheaply for you." Thunder Tiger gave more than half of the royal griffin to Kenlohag and gave him a lot of rights.

Because he believes that Ken Lohag must be a person who can't sit still, but no matter how he says, he is also a famous general and hero, and he has a certain judgment on the battlefield, rather than letting him defend the city, it is better to give him some troops, let it go, and maybe it can also have the effect of a surprise soldier.

Offense is the best means of defense, and Lei Laohu believes that this sentence must have a reason for its existence.

"Good!" Kenlohag replied in a loud voice, and then excitedly led the 2 teams of royal griffons out of Southwest City.

"Keanu, Smith, you follow Leonardo's orders, and are mainly responsible for the defense of the long-range troops."

"Yes!" The three of them answered in unison, then left the council hall and began to set up defenses on the walls.

And the main reason why Lei Lao Tiger will continue to arrange Leonardo to command the other 2 heroes to fight is Leonardo's strategic skills - leadership.

Although the intelligence of ordinary heroes is much lower than that of famous heroes, and there is no ** character of famous heroes, every ordinary hero has his own good job.

From a certain aspect alone, ordinary heroes are not necessarily worse than famous heroes, but all things considered, ordinary heroes are not as comprehensive as famous heroes.

And this can be judged from the strategic skills attached to ordinary heroes, such as Leonardo, his initial strategic skill is leadership, although leadership increases morale, and the number of troops, but its hidden effect is that this hero is good at leading troops to fight.

If you only talk about leadership ability, Leonardo, as an ordinary hero, is not necessarily worse than some famous generals who are not good at leading troops, and may even be much stronger, for example, some famous generals and heroes who are good at magic skills are much worse than Leonardo who has leadership skills in terms of their ability to lead troops.

After everyone left the council hall, Lei Laohu checked the remaining resources in Southwest City.

After looking at the remaining resources, Lei Laohu patted his forehead with a helpless face, and began the construction of the city.

Leonardo is indeed not good at the work of city construction, although Lei Laohu has already given the other party an order, but the other party has only recruited all the troops in the city, but he is not so concerned about the construction of defense facilities, at least there are still a lot of ordinary resources left in Southwest City, these resources are completely enough for Southwest City to be promoted to level 5 city, and there is still a surplus.

Without the slightest hesitation, Lei Lao Hu directly started the upgrade work, first upgrading the city to level 5 in one go, and then building the most basic defense facilities.

Since then, there are not many gold coins and ordinary resources left in the Southwest City, but there are still a lot of reserves of scarce resources.

However, Thunder Tiger did not, and only stopped the construction work after continuing to build the market, the blacksmith shop, the brotherhood, the lighthouse, and the first-level magic guild.

The Brotherhood can increase the morale of the defending troops, and needless to say, the defending side must be surrounded by enemies, so morale is very important.

The role of the blacksmith is also obvious, due to the huge ammunition consumption of ranged troops in the defense of the city, a large amount of ammunition is required to replenish the consumption.

The lighthouse can give early warning, so that you can know the movement of the enemy in time.

And the first-level magic guild, in addition to Leonardo and other 3 people to learn magic, also has a hidden role, but this role is not known to players for the time being, except for the reborn thunder tiger.

Speeding up the mana regeneration of the defending heroes is the hidden attribute of the Magic Guild, which is very useful, because magic can make or break a battle in some cases.

As for the market, although it seems to have little effect, but for the current southwest city, it has the most huge effect, after the construction of these buildings, the ordinary resources are basically exhausted, and Lei Laohu needs to use the market to exchange for some gold coins and ordinary resources.

Leaving the newly upgraded Congress, Lei Lao went directly to the market.

Although it is a dungeon, players can still trade in the market, but the trading object in this market can only be the merchant in this dungeon, and the scope of the transaction is relatively narrow, and the purchasing power is not so strong.

Although the purchasing power is not strong, in order to raise materials faster, Lei Laohu set a selling price that is slightly lower than the market price, and soon, all the scarce resources were sold, all of which were exchanged for two ordinary resources such as wood and ore and a small amount of gold coins.

After completing the transaction, he rushed to the Magic Guild non-stop, this time he did not let the three heroes choose their own magic, but directly suggested that the three of them learn the three magic of dispelling**, bloodthirsty thaumaturgy and Holy Spirit blessing respectively.

(Basic Dispel**: Level 1 support magic of the water system, removes the influence of negative magic of your 1 squad)

(Basic Bloodthirsty Thaumaturgy: Fire Level 1 Support Magic, Increases Attack of Squad 1 by 30, Lasts Wisdom Minutes)

(Basic Holy Spirit Blessing: Water Level 1 Support Magic, Friendly Squad 1 has a chance of 1.5x damage with Wisdom % for Wisdom minutes)
