Soon, an hour passed.

Both of them were wind mages and were not affected at all by the strong winds, so they flew at an extremely fast speed, covering a distance of seven or eight hundred kilometers in five hours.

At this moment, several faint life forces entered the two people's mental perception.

There were a few polar bears, a father bear, a mother bear, and a few cubs. They were digging hard on the ground. They had already dug a big hole, and it seemed that they were about to see the water surface.

When sensing the two people's mental power, the father bear and the mother bear immediately raised their heads and howled madly towards the sky.

Dolai felt a little shocked that these seemingly insignificant white bears had actually reached level three in strength.

He thought about it for a moment and said, "Ashe, we may have lost our direction. We are now flying north of the Arctic Ice Field. Do you want to take a break? Wait until the wind dies down or until daytime to figure out the direction before going."

When you reach the far north, a compass is of no use, because the range of north here is too vague. The compass will swing everywhere and there is no accurate direction at all. You can only look at the sun or the stars to determine the direction.

It was Ash's first time going out, so how could she understand all this? After Doley explained it, she immediately understood.

If we fly along the edge of the ice field, we should not be able to see these polar bears. Now we should be flying straight towards the Arctic ice field.

It is said that the Far North has a very strong geomagnetic force that can interfere with people's judgment, so it is normal to deviate from the direction while flying.

She told Dole what she knew.

Duolai was stunned. What kind of power is this? Can it interfere with people's spiritual power?

The two discussed it and decided to stop and wait for the wind to die down, for the sun to come out, or for there to be a starry sky before flying.

In the midst of the wind and snow, Dolai found a flat ice surface, put out the wizard tower, and then crawled in.

The power of the wizard tower then spread out, madly absorbing and devouring the surrounding power to replenish itself. An icy wind blew through the sky and fell on the wizard tower, making crackling sounds.

After entering the wizard tower, Dolai shuddered. It was really much warmer in here.

But Ash said seriously, "Send me up there. I think it will be better outside."

Dolai nodded, and a white light flashed before his eyes, and Ashe disappeared.

A world like this with strong winds and heavy snow is a disaster for any living creature, but for those who practice the Ice and Snow Goddess Meditation Method, it is the perfect environment because they are born to adapt to such a place.

Dolai slowly came to the laboratory, and while using the power of the wizard tower to restore his own strength, he was thinking about the next step of the bloodline experiment.

The bloodline of a crocodile dragon is actually very complex. The lower the level of the crocodile dragon, the more complex it is. After purification, it is divided into several parts, and these parts can be purified again, so the deepest part cannot be seen at all.

Although there was a difference between the high-level crocodile dragon bloodline, Dolai was not blind at last. With his understanding of dragon power, Dolai still had some clues. But the problem came. Due to the current environment and the lack of biological references, even if these bloodline powers were purified, there was no way to inject and observe them.

The crocodile dragon has at least two bloodlines in its body, one is the crocodile bloodline, and the other is the bloodline of an unknown dragon.

After a few days of reference and experimentation, Dolai has ruled out at least two types of dragon bloodlines, one is the blue dragon and the other is the red dragon. He has never seen any other dragon blood.

He had never seen the bloodlines of the three kinds of five-colored dragons: the black dragon, the green dragon, and the white dragon. However, as long as it was a dragon, the same kind of power was contained in their bloodlines, which had been analyzed over the years. It was a symbol of pure power and seemed to represent the law of the purest force in nature.

However, in addition to dragon blood, any dragon species also has the purest magical energy, and other powers are contained in its blood. Based on current knowledge, Dolai is unable to separate them and can only treat dragon power and magical power as a mixture.

This is the essence of bloodline research, to study the original, most primitive power, and separate it for use on oneself.

Dolai's strength has reached the limit of level four, and no further training will improve it unless he finds a real elemental storm. Therefore, he can only recover while doing blood experiments.

This time, the two of them didn't bring anyone with them except Bal. This old man spent all day sleeping, looking extremely free and easy.

The first floor of the wizard tower.

In the closed prison, several level 4 wizards, level 4 warriors, and level 5 wizards were all locked up together, both men and women.

At this time, all of them were hung up by silk threads, hanging in the air, looking extremely miserable.

They were not tortured, but they looked very depressed, because those silk threads had the most stringent restrictions in the wizard tower, which were constantly draining their strength. As soon as they recovered a little bit of strength, it would be drained away immediately.

Without strength, everyone was weak, and even communication was reduced to speaking in the simplest language.

"It's been more than ten days. This couple of bastards must have entered the Far North. Damn them." A soldier cursed loudly in anger.

A wizard hanging next to him said weakly, "Okay, if you don't want to be the next test subject, just shut up."

He was a wizard, his physique was far inferior to that of a warrior, and he was seriously weak at this moment.

The soldier said viciously, "When I took this step, I didn't expect to die in good health, but I didn't expect to die so miserably. If I could commit suicide, I would have followed in the footsteps of my brothers. Damn it, come and kill me, useless bastard."

He suddenly began to curse loudly again.

At this moment, a voice came from above, "Emmm, it seems that you are in good spirits. Today's test subject is you. I have an interesting experiment. I hope you can withstand it. If you can withstand it, you can become the most powerful warrior. If you can't withstand it, hehe."

The voice was naturally Dole's.

The test subject is of course useful, but if one is used, there is one less.

The warrior suddenly cursed loudly again, "You black wizard, bastard..." As the silk thread was retracted, the warrior's body immediately trembled, and lightning bolts flowed into his body along the silk thread. The warrior curled up into a ball due to the electricity.

Then, his body was pulled by the silk thread, slowly rising up and soon disappeared from the sight of others.

Seeing this, even though these people had already anticipated their own deaths, they still felt endless despair.

…

In the laboratory.

Dolai changed into a white wizard robe, covering himself completely with only a pair of eyes exposed.

On the experimental table, the man was lying flat on it, his eyes wide open, a hair ball stuffed in his mouth, and he was lying there motionless.
