Back at the wizard tower, the two began to experiment.

Ashe is very enthusiastic about doing experiments.

Dolai prepared the equipment. There was a little bit of reserve in the wizard tower. Some things could be used directly, and some equipment needed to be refined on site, including separators, observers, spirit detectors, matter separators, new alchemy tables, and so on.

He had been preparing all these just now. After Ashe came back, Dole asked him to take a look at the basic magic patterns first, and then he prepared on the side.

He had an alchemy table with flames burning on it. Soon, various materials were purified and transformed in his hands to form new devices. After the new devices were formed, magic patterns appeared out of thin air in Dolai's hands and were imprinted on the new devices.

Ashe was dazzled by all this. Dolai's use of magic patterns was simply dazzling and overwhelming. Looking back at herself, even the most basic and simple magic patterns were very clumsy in her hands.

However, Ashe was not discouraged. He knew that this was the result of Dolai's years of practice. This was his talent and his ability. As long as he could have half of his ability, his future achievements in alchemy would not be far behind.

She cheered herself up.

Soon night fell.

On the river, a powerful aura swam back and forth at the bottom of the river. Some ignorant bears and beasts were instantly eaten by the restless and powerful aura when they were drinking water or hunting by the river. For a while, the area around the river was quiet and almost no creature dared to approach.

The level five crocodile dragon had already developed intelligence. He felt that the number of crocodile dragons here had suddenly decreased by more than half.

Where did they go?

So he kept patrolling the river, trying to find their trace.

…

The night passed quickly, and Dole had some more tools at hand, which were used to observe blood.

After finishing all this, the two took out the blood of crocodile dragons of various levels, began to observe it slowly, and tried to separate it.

Observation is the first step, separation is the second step, and then we continue to observe and experiment to see which part of the blood the crocodile dragon's bloodline comes from.

The power of blood is so special that he needs to keep testing and trying to find the most fundamental thing. He cannot be impatient at all.

The Kabash blood experiment detailed the standard procedures and observation directions of the blood experiment. Dolai and the others naturally processed the blood strictly according to what was said in it. It only took them more than half a day to purify a bunch of black and blood-red viscous liquid from the blood of the low-level crocodile dragon. From the blood, a powerful aura belonging to the crocodile dragon gradually emerged.

This is the pure blood of a low-level crocodile dragon, and the blood power contained in it is not strong.

The two put it aside and began to purify the third-level crocodile dragon and the fourth-level crocodile dragon.

The pure blood of the third-level crocodile dragon is more crimson, but it still presents a black attitude. The blood power is more intense, and the dragon attribute aura is more intense, as if the blood itself carries a powerful force. The blood of the fourth-level crocodile dragon turns into real blood red, and a dragon power that Dolai has seen before emerges.

Obtaining these three different levels of blood is just the beginning of the experiment.

At this time, more than a day had passed and the energy of the wizard tower had been replenished.

The experiment can be carried out at any time, but the distance to the Far North will not be shortened. Therefore, after seeing that the energy was fully replenished, Dolai put down the experiment and handed it over to Ashe. He took back the formation hidden around him, and then activated the formation. The wizard tower soared into the sky in the night.

Dozens of kilometers away, the crocodile dragon felt this breath and howled madly towards the sky. The powerful breath made all creatures within several kilometers around tremble with fear.

However, he wanted to chase after Dolai and the other man, but he could only watch the black shadow disappear quickly before his eyes.

After the wizard tower flew into the sky, Dolai naturally felt the prying eyes around him. He directly climbed the wizard tower to a height of more than 6,000 meters, changed direction, and flew quickly towards the far north.

At this time, the wizard tower has fully activated the concealment formation. Even if the creatures around are spying, they will not be able to find him at all.

After the wizard tower stabilized, Dolai observed the wizard tower itself while looking at the direction. He took Ashe's map, compared the direction, and constantly adjusted the direction of the wizard tower's flight.

Soon, after he determined the direction, he handed over the wizard tower to the semi-intelligent formation and breathed a sigh of relief.

It is not difficult to operate the wizard tower, but what is difficult is what happens after the operation.

After the wizard tower flew smoothly, Dolai looked at the map and determined the next stop.

The Eternal Forest is very large, stretching 20,000 to 30,000 kilometers from north to south. The Wizard Tower took two days to fly only about 3,000 kilometers. Even if it flies at full speed, it will take another eight or nine days, and there cannot be any mistakes in the meantime.

Looking at the current energy reserves of the Wizard Tower, if Dolai does not modify the core, it can only fly for two days at most. Therefore, after smoothly entering the high-altitude flight, Dolai wondered whether it was necessary to upgrade the core of the Tower of Babel. The current energy reserves were really too little. As for the bloodline test, he could let Ashe play on the side and he could just watch it himself.

It is already October. The further north we go, the lower the temperature, the lower the air pressure at high altitudes, and the smaller the resistance to flight. Dolai looked at the various indicators of the wizard tower and it seems that they can fly for a longer time.

After moving northward for a while, the air became very cold. Looking down from above, some places were already filled with white snowflakes, as if it had snowed, while some places had completely turned yellow, indicating that winter had already arrived here.

One day later.

The clouds were getting lower and lower, but Dolai did not control the wizard tower to descend. Instead, it increased its altitude. Because according to his information, there were all kinds of powerful birds, falcons, eagles, eagles and other powerful high-altitude creatures, as well as legendary creatures such as the Roc lingering in the north, so he did not dare to fly too low.

The scenery above the sky is the same everywhere. I have been watching it for two days and three days. From the initial feeling that nature was so magnificent, to now feeling bored when I see the clouds outside.

However, Dolai soon stopped feeling bored because there was a large cloud ahead, covering an area of ​​a thousand kilometers, and it seemed to be snowing ahead.

The clouds were below us, so we could clearly see the changes in the clouds. There were even small whirlpools formed in some places, but they were all small.

That is the embryonic form of a storm, but in winter weather like this, the temperature changes are too low and no strong storm will form, so this kind of cloud will disappear quickly.

This is the law of nature and the most natural law.

Dole has experienced all of this.

He wanted to float above the clouds, carefully observe the changes in the clouds, and experience the rhythm between the wind and the clouds, but now was not a good time.

At this moment, he saw what seemed to be some huge creature flying through the clouds.
