In the following time, Emperor Shi Tian fully demonstrated the essence of an infrastructure madman.

In just one day, the main city was built, using the original routine, the walls of the five-story bastion, plus three defensive towers.

Of course, this seemingly solid city wall can only defend against ordinary attacks, and because it is not reinforced by magic, it is easy to be torn down by spells.

For this reason, Emperor Shakti had to transfer 500 dwarven rune mages to magically strengthen the city walls.

At the same time, Emperor Shi Tian also personally led a total of more than 500 earth monks to build five giant protective towers ten miles away from the city wall.

Fortunately, the territory of the underworld is all under the Tower of Babel, so you only need to defend against attacks from three directions.

Therefore, Emperor Shi Tian can use five protective towers to protect his main city, otherwise he has to build eight protective towers like satellite cities.

With a diameter of more than 300 meters, these towers are also a layered bastion structure, which eventually gradually shrinks upwards to form a roof at a height of more than 200 meters.

The tower is divided into more than a dozen floors, each with a number of balconies for heavy weapons such as 20mm cannons, heavy machine guns or rocket launchers.

In addition, a large amount of water, food and ammunition are stored inside the tower, which can hold on to the fight for a long time.

In addition, a moat with a depth of 10 meters and a width of 30 meters was dug outside the tower, which further created difficulties for the attackers.

And the soil dug out of the moat was used by the earth mage for the construction of the protective tower, which can be described as killing two birds with one stone.

The two towers are only about five or six kilometers apart, so they can be clearly seen from each other and can be supported by rocket artillery.

With these five satellite cities, the security of the mage realm will be greatly improved.

However, Emperor Shi Tian was not satisfied, and he also built twenty or thirty small fortresses, which were distributed between the satellite city and the main city.

These small bastions, only about a hundred meters in diameter and only thirty or forty meters in height, are huddled behind the side of the satellite city.

These bastions are only about a kilometer away from the satellite city, and they can easily be hit by both heavy machine guns and 20mm cannons.

So, if anyone dared to attack the satellite city, they would be attacked by small bastions on the left and right at the same time.

And if they want to bypass the satellite city and directly attack the small fortress, then they will have to withstand the huge firepower of the satellite city, as well as the fire support of other small dragon castles.

Therefore, with these small bastions, as well as the in-depth protection of the satellite city, the defense capability of the main city will be greatly improved.

In particular, Emperor Shakti also arranged a lot of mobile troops, which were distributed inside these small fortresses.

If an enemy attacks, they will quickly assemble and harass the enemy, preventing them from attacking the castle properly.

And if the enemy pursues them, they will turn around and run.

Anyway, their purpose is actually to delay time, because they are safe in this area, but others have to endure the attacks of satellite cities and bastions all the time.

Emperor Shi Tian knew that if he defended for a long time, he would lose it, so he would place these mobile troops to facilitate support and mobilization at any time.

Whether it is a satellite city or a fortress, it is a very huge project, but Emperor Shi Tian was stunned that with the earth monks in his hands, it was completed in just three days.

And among them, the magic weapon of the earth system, the role of the earth spirit bead is indispensable.

After more than a year of recuperation, the quality of the Earth Spirit Bead has been improved, and the mana stored in it has even exceeded the mana of the earth monk himself, and the recovery speed is much faster, which is equivalent to every earth monk has double the mana, and double the recovery speed.

Coupled with the large amount of magic food such as fruit honey wine provided by Emperor Shakti, their magic recovery speed increased a lot again.

It is precisely because of this that they were able to complete this huge project in such a short time.

In contrast, although there were as many as five hundred dwarven rune mages, their efficiency was much worse, and until three days passed, they had only completed the rune enchantment task in the main city.

And it's only a primary enchantment, barely able to resist spells below level 3.

Emperor Shi Tian was very speechless about this, but there was nothing he could do, in fact, he also knew that the rune mages had tried their best, in the past three days, although they were all trying to provide good food and drink, but they were still tired and thin, obviously not that they were lazy, but that they really couldn't do it.

But the problem is that the military is like fire, and the enemy will not stop you from fighting you because you are not prepared.

For example, this time, although Emperor Shi Tian expected to be attacked, and he was also desperately building protective buildings, he was still not fully prepared and received a battle report.

There are two small detachments sent by Emperor Shakti, who have already exchanged fire with the enemy.

According to Emperor Shitian's order, the squad only tasted the basics and did not fight the enemy.

But despite this, they still suffered a lot of losses, almost losing 1/3 of their troops.

You must know that Emperor Shitian's squad is not vegetarian, although there are only ten cave people shooters, but there is a necromantic chariot commander, plus about 300 crazy iron dogs to follow.

An idle enemy, one or two thousand, may not be able to beat them.

Even if you can beat them, you may not be able to kill them, who called Crazy Iron Dog's mobility so high.

But this time, even though they had been very careful, they still suffered such a big loss, which shocked Emperor Shakti.

Emperor Shi Tian hurriedly retrieved the memory of the detachment commander to see what was going on?

As a result, it didn't matter, and it directly startled Emperor Shi Tian.

The first team encountered the cavalry scouts sent by the other party, and the other party had about 50 people, all bronze-level human knights.

Dressed in neat armor and armed with spears, they directly launched a charge against Emperor Shakti's squad.

In the face of these light cavalry, which have an advantage in speed and are not strong in defense, Emperor Shitian's scout squad is not cowardly at all.

The first was the rocket artillery greeting, and ten rocket launchers roared past them, slamming into their ranks.

But unfortunately, after all kinds of magic sounded, in addition to creating a lot of beautiful sound and light effects, it did not cause any damage to people.

It turned out that the knight led by the other party was a veteran of many years, and at the first time when the rocket artillery rushed over, he activated the protection spell, and it was three different protection spells, which protected everyone at once, and carried the attack of ten spells, safe and sound.

And at this interval, the opponent's speed suddenly more than doubled, and almost in the blink of an eye, he was about to kill in front of him.

In desperation, the commander of the squad, Tentacle Ji, had no choice but to immediately activate the 20mm cannon and shoot fiercely at the opponent.

At the same time, she also activated two protection spells, two auxiliary spells, and then ordered 300 crazy iron dogs to attack.

I have to say that the power of the 20mm cannon is still very terrifying, and the rate of fire of 4,000 rounds per minute makes him a killing machine.

Under the frantic fire of the machine guns, although the light cavalry on the opposite side showed their fighting spirit, they did not stand up for much time, and the light cavalry in front of them was quickly exhausted, and then they were shattered by the 20mm machine gun.

Regardless of the men and horses, they were lying on the ground, which created an obstacle for the troops behind them, forcing them to slow down.

And taking advantage of this opportunity, Crazy Iron Dog finally rushed forward and bit the opponent's war horses and knights fiercely.

The two sides officially began a tragic melee hand-to-hand combat, and at this time, it was obvious that the strength of the people was coming.

When Crazy Iron Dog attacks alone, it is basically cut in two, and the opponent's weapon is a magic alchemy weapon, plus the blessing of fighting spirit and auxiliary magic, it can easily cut off Crazy Iron Dog.

Moreover, Emperor Shi Tian noticed that the reason why the other party was able to kill Crazy Iron Dog so easily was that in addition to their weapons and magic blessings, there was also one of the most important reasons, that is, people's martial arts.

These cavalrymen have obviously been systematically trained in martial arts, and have developed a special fighting spirit slash, which can burst out with very powerful lethality in an instant, so that even the crazy iron dog blessed with spells can cut it in two.

However, it is a pity that these light cavalry are not only small in number, but also have a long-range attack method, although it is very pleasant to kill dogs, but they cannot go below the 20 mm cannon and the crazy bombardment of the caveman shooters.

So in the end, all 50 bronze-level knights died tragically under the muzzle of the gun, but before they died, they also took away more than a hundred crazy iron dogs.

After calculation, the large number of Emperor Shi Tian's side lost twice as much as others, which is really a bit of a loss.

But fortunately, in the end, it was won, and the winner had the right to clean up the battlefield, so this time the harvest was not bad, and dozens of complete bronze weapons could be found, but the complete armor did not exist, and it was all shattered by the machine cannon.

Throughout the battle, the commander of the squad performed quite well, and if they had chosen to flee at that time, the losses could have been more than twice as great.

Because people have obviously released special skills, they can run much faster than you, and it is impossible to escape, and don't even think about flying other people's kites.

Therefore, at this time, you should take the initiative to face the battle, and you must not be cowardly.

If the Commander made a mistake, it was that she wasn't smart enough.

If Emperor Shi personally commanded this battle, he would immediately throw grenades, all flash grenades, and cloud bombs as soon as the rocket artillery failed, in short, to destroy the opponent's eyesight, and then he could easily clean them up.

Anyway, Emperor Shi didn't believe the other party, and he also carried a dispel magic scroll.

After all, it's just some cavalry who are exploring the way, and it is very suitable to bring auxiliary spells suitable for combat, or protective spells, or even attack spells, but in the dispel spell, it is a bit too much.
