Ashe thought about it, "In fact, the sea is not entirely inhabited by Warcraft. There are still some human islands. If this is the East China Sea, if the direction is correct, there are at least three human countries and two powerful wizard groups occupying a piece of land. If we fly towards the east coast and find one of these places, it means we are in the right direction."

In the Far North, the sense of direction is extremely poor and it is easy to get lost. Although they have determined the direction so far, they are still not sure where they are.

At this time, Bal was lying on the side calmly, not giving any opinions.

Dolai thought for a moment and said slowly, "The location and other things should be clear at night. I can read the stars. Let's fly over there first and take a look. You need to master the wizard tower. I want to add some rune arrays to the energy core of the wizard tower. The energy level is still a little low."

After his strength increased, Duolai felt that his control was strengthened again. Now it should not be a problem to transform the energy core again.

After the two discussed for more than ten minutes, the three of them went into the wizard tower, and then the wizard tower rose from the ground and rushed into the sky.

Above the sea, there are blue waves. Looking down from an altitude of three thousand meters, there is a thin layer of fog in the sky. The ground is azure blue, the sky is azure blue, and there is an illusion in the middle. It looks very spectacular and ethereal.

This scenery looks beautiful, but it is very boring to watch it every day. After watching it for several months, they are already tired of it and they wish they could go back right now.

In the middle of the wizard tower, Dole sat cross-legged on the edge of the energy core, carefully examining the energy core. Next to him, Ashe controlled the wizard tower while watching Dole's movements.

She now also wants to learn about wizard formations, so she plans to study them seriously.

Dole thought about it, carefully reviewed the blueprint of the Tower of Babel, and took out the energy core alone.

The current core is a level-five core, which involves 120,000 magic pattern structures, and the whole is the same. If you want to upgrade to a level-six core to accommodate more energy, you need to add 120,000 structures. It seems simple to add new structures without changing the original magic patterns, but it is actually very difficult, because it is difficult to avoid touching the previous structures.

The energy core was refined by Dolai himself, and he knew very well what problems were inside it. So, after carefully studying the structure of the Tower of Babel, Dolai began to act.

Magical power surged around him, and huge amounts of energy emanated from his body. Soon, magic patterns formed around him and then slowly flew towards the energy core.

Each of these magic patterns is different from another, some are used to store energy, some are used to guide energy, and some are used to stimulate energy. High-level and low-level ones are used in different combinations, and Dolai's mental power needs to make thousands of changes in one second.

This exaggerated way of using mental power left Ashe standing next to him dumbfounded.

Is this still a level five wizard? Even a normal level six alchemist can't do this.

She tried hard to observe Modole's control method, but finally found out with frustration that she couldn't do it at all.

However, after entering level five and forming the ice and snow field, she has also been trying this method of control. There are now countless witchcraft models placed in the field. She is not unfamiliar with this, but the gap between the two is too big.

After Duolai entered level five, he directly skipped the early stage and entered the middle stage, while she was still lingering in the early stage. This is the gap.

To put it bluntly, Dolai can now defeat her with one hand, which makes the proud Ashe feel a little uncomfortable.

The gap is too big.

The wizard tower became invisible and flew rapidly in the sky. Soon it was night, and the two men and the dog had already left the previous island, flying more than 2,000 kilometers away, and bypassed a huge thundercloud in the middle.

The sea is not endless. In some places, there are many islands. Where there are islands, there are uplifted land veins. The sea water is not very deep. Such places can easily form shallow ecology, nurturing countless creatures and giving birth to countless monsters.

The sea has always been a forbidden area for humans. Except for some extremely powerful humans who dare to come to the deep sea, generally only large merchant caravans and fleets dare to come in. Normally, no one can be seen at all.

So, I flew all the way until night and didn't meet anyone.

At night, the sun sets and the stars in the sky gradually appear.

At this time, Dole put down the work at hand, went to the top of the wizard tower, and carefully distinguished one or two things.

The starry sky is the most profound, but once you understand the rules, it is actually very simple. The positions of most of the starlight in the starry sky are unchanged, and based on the positions of these stars, you can determine your own position.

Dole pondered for a while, took out some papers, drew a few pictures, and determined that he was still tens of thousands of kilometers away from Watsonburg of the Glorious Empire.

"According to the star map, the stars in the sky should look like this." Dolai said to Ashe beside him while drawing.

He wrote and drew, and soon a lifelike star map appeared on the paper.

"But now, the star map above our heads looks like this. According to the changes in the star map every hour, our current position is here, and the Watsonburg is here. If we measure it specifically, based on our one-hour flight distance, the straight-line distance is about 15,000 kilometers."

Dole was an observant man and quickly drew out detailed road signs.

Of course, he didn't figure this out on his own, but learned it from the books he read.

Ai looked at Duolai with little stars in his eyes.

"That's amazing. If what you said is true, using this method, the distance of the entire world can be measured?"

Ashe thought about this question.

Dolai nodded. "The distance between worlds is not a secret among the top leaders. They just don't want ordinary people to know. The whole world is round. The top leaders actually know the situation between each continent. If you don't believe me, go ask your father."

Although Dolai didn't know these things, he could figure them out with his toes.

Ashe sighed. She only knew how to practice every day, so how could she know these things? Dolai was really amazing.

She looked at the blueprint, then at the sky, but couldn't see any connection between them. It was too complicated.

Indicating the position with her hands, Ashe added the map of the Glorious Empire on the drawing, and the approximate location of the coastline came out. Then she marked the positions of the two wizard forces on the sea. She was surprised to find that the two men did not pass there at all.

If they were flying in a straight line now, they would probably reach any of the three southeastern provinces of the Glorious Empire, and then cross most of the empire before returning to Watsonburg. This distance was too far.

Fortunately, there was the wizard tower, otherwise she couldn't imagine that she could go so far.
