Wang Zhaodi was distressed, and the blacksmith and the iron wolf came to see her together, and handed over all the seized magic crystals to her.

Wang Zhaodi looked at the large pile of magic crystals piled on the ground, and said in surprise, "There are so many magic crystals!"

The blacksmith and the iron wolf nodded together, and the iron wolf said, "Each trebuchet is powered by magic crystals, and after we destroyed the trebuchet, we took down the magic crystals on it, and we destroyed more than a hundred trebuchets in total, so there should be more than a hundred magic crystals!"

Brother Wang Zhaodi walked up, took a piece of the magic crystal in his hand, and said while playing, "There are so many magic crystals, if you can use them, maybe they will win by surprise!"

The blacksmith and the iron wolf were silent, because their ancient warrior clan has always been a race that takes pride in battle, and they have always been amateurs in the use of magic, so even if a large number of magic crystals have been seized now, they really don't know how to use them!

In Wang Zhaodi's mind, a picture emerged, that is, when she was in the Sea Elf Castle, she saw with her own eyes that the Sea Elf Castle used the magic tower in the castle to quickly defeat the huge fish-man army.

So Wang Zhaodi asked the blacksmith and the iron wolf to retreat first, and she beckoned a sea elf from the elven ring to come out, and then asked him, "Let me ask you, how was the magic tower in the sea elf castle built?

Wang Zhaodi was lucky this time, the sea elf she summoned was a high-level sea elf, and he knew everything about the construction and function of the magic tower.

So this high-level sea elf began to tell Wang Zhaodi how to build a magic tower in the castle, and what is the use of magic towers.

Here's an introduction to this sea elf.

In order to build a magic tower successfully, you must collect a certain amount of materials, according to the level of the magic tower, the materials required will gradually increase, the first-level magic tower, to build, only need simple wood and stone, the second-level magic tower, in addition to wood and stone, also need additional sulfur, and from the second-level tower, to the third-level tower, you need additional gems, upgrade the fourth-level and fifth-level towers, you need additional magic crystals!

The first-level magic tower can unleash very little magic, only simple attack spells such as magic arrows and magic fireballs, and the power of the spells is also very small, and the attack distance is also very limited.

The second-level magic tower, there are many magic to choose from, the most important of which is to use the lightning technique, this spell is more powerful, and the attack distance is also very far, it can already cover a range of 100 meters around the castle, that is, as long as the enemy appears within 100 meters around the castle, you can launch a thunderbolt attack the enemy at any time.

The third-level magic tower, the magic that can be used, there is a meteor shower, and there is a chain of lightning, both of which are group attack magic, and there is an effective range of attacks, and it is even farther, and it can already attack targets two hundred meters away from the castle. However, these powerful spells, every time they are fired, will heat up the magic tower, so you must wait until the magic tower has cooled down before you can launch a second time, otherwise, the magic tower will spontaneously combust and burn completely!

Fourth-level and fifth-level magic, this sea elf has never seen it, because it is said that these magic spells are forbidden spells between heaven and earth, and once cast, it will cause a devastating blow to any creature between heaven and earth, that is, both the enemy and the enemy will die together, so unless it really comes to the last moment, and the enemy will die together, otherwise, no one will use the fourth-level and fifth-level magic.

Wang Zhaodi probably understood what was going on in the magic tower, but she was very curious about what the fourth-level magic and the fifth-level magic were, so she asked the sea elf and said, "You haven't seen the fourth-level and fifth-level magic, so have you heard of it, what are these magic called?"

The sea elf said, "I've really heard of this, it is said that the fourth-level magic, the most terrifying is the Doomsday Judgment, which is between heaven and earth, a rain of fire falls, like a rainstorm of fireballs, that destructive power, it is conceivable, no living creature can survive!

Wang Zhaodi nodded and said, "If it really has such great power, then you really have to be cautious!"

The sea elf sighed and said, "High Priest, if you have nothing else to do, I'm leaving!"

Wang Zhaodi sighed and said, "Okay, you can step down!"

The sea elf immediately turned into a spiritual light and returned to the Elven Ring.

Wang Zhaodi immediately called the guards to gather all the craftsmen in the castle, and she asked these craftsmen to build a second-level magic tower in the shortest possible time.

Those craftsmen received the order, and immediately began to go all out to build the magic tower, the Zerg outside the castle, braved the rain of arrows to build bridges, the craftsmen outside the city, compared to the speed of construction, three days later, both sides completed the task, in these three days, the Zerg in the canyon outside the castle, erected a total of fifty bridges, these fifty bridges, can ensure that the Zerg army, in a very short time, together on the city wall.

And the craftsmen in the castle, in three days, also successfully built a second-level magic tower, a second-level magic tower, is already very grand, it is almost twenty meters above the city wall, standing on the magic tower, you can have a bird's eye view of everything around the castle.

Wang Zhaodi was very excited to climb the magic tower road, she saw that outside the castle, a large area was full of black and oppressive Zerg army, her mood was heavy, but she plucked up her courage, she firmly believed that relying on this second-level magic tower, she would definitely be able to defend the ancient city.

After the Zerg army built the bridge, it began to sound a huge conch, in the sound of the conch, all the Zerg began to charge towards the castle, Wang Zhaodi stood on the magic tower, watching the Zerg move, they were black and pressed, after they began to move, it was like black water rolling up, these black water streams, began to impact the walls of the ancient city, they were blocked by the city wall, and they gathered, as if the water flow was blocked, it rose high!

But in fact, it was not that the water rose after it was blocked, but that the Zerg swarmed and began to climb the city wall, and the black pressure of the Zerg all climbed up along the city wall, so that the ancient warriors standing on the city wall to guard were overwhelmed, and many of the Zerg's hellhounds had already rushed up to the city wall and started hand-to-hand combat with the ancient warriors!
