This time it took three days to refine the Lei Tower. After it was refined, it was time for the next one.

Dolai had already mastered the core runes of these elemental wizard towers. Each core rune formation was actually a rule. Although Dolai was now wearing the shell of Storm Meditation, he had basically encountered all the rules of the nine elements. In other words, he could master them after spending some time. Level eight or even level nine were not a problem. The difficulty was that he did not have much time now.

The Nightmare Ancestor has never given up on infiltrating the city of Albis. He is very annoyed by the infiltration of Dolai's forces. Recently, the Nightmare Ancestor's tentacles have stretched very long and started to invade the eighth level. This makes Dolai feel a sense of urgency. This is the key factor for him to promote the wizards.

After finishing these wizard towers, he prepared to upgrade the Turin Bone Tower and the Tower of Babel. After these two wizard towers were upgraded to level eight, he would not be afraid of ordinary level eight towers.

At level eight, you have mastered at least three rules. Above level eight, you can follow the path of laws. At level seven, you don’t care much, but at level eight, you have to pay attention.

The power of the two rules added together is not one plus one, but one plus one equals eleven, which is extremely exaggerated. For example, the earth element and the fire element added together can explode with one thousand percent of power, directly promoted from the disaster level to the horror level. Originally, it was just the scale of a volcanic eruption, but after reaching level eight, it would immediately be promoted to the scene of countless volcanic eruptions. That would be truly terrifying.

Therefore, those above level eight are forbidden to attack, this is the reason.

If Dolai reaches level eight and fights the black dragon of Beiyuan Mountain, I'm afraid he can completely destroy the entire Beiyuan Mountain.

With one strike, he could destroy several mountaintops. After an hour's fighting, the Beiyuan Mountains were destroyed.

It makes sense that you can't attack at will when you are above level eight.

The destructive power of level seven is much smaller than that of level eight, and if you pay attention to controlling it, the destructive power is not that great. If you use it at full strength, it is just similar to a natural disaster, at most the scale of a magnitude 6 or 7 earthquake. The dragon bat, Dolai, and the three-headed dragon lizard have fought so many times, and they have destroyed dozens of mountains, that's all.

Therefore, if the Black Dragon is controlled by the Nightmare, Dolai will have to find a way to resist. The seventh-level wizard tower cluster and the eighth-level wizard tower are the fastest things he can achieve at the moment.

Nightmare, this old guy who has lived for more than a thousand years, really knows how to cause trouble.

Duolai was refining the recipe while thinking about these questions, without stopping his hands.

Including a few days of rest in between, it took a full month to finally upgrade all the wizard towers to level seven. Not only was the entire wizard tower group much taller, but the energy fluctuations and majesty it emitted also became several times heavier. Around the wizard tower group, the elemental energy became more abundant, emitting mysterious fluctuations.

The elemental wizards were very excited. It was the first time they felt such a strong elemental fluctuation, and their practice was much more efficient.

Especially the eight tower masters, after connecting with the Wizard Tower, they felt that their strength increased faster.

That's what the wizard tower is for.

This place is not only a place to live, but also a fortress, a training room, a laboratory, and the highest alchemical masterpiece of human wizards.

Of course, in addition to the Wizard Tower, there are other greatest alchemical products of mankind, such as airships, but the Wizard Tower is undoubtedly the most representative.

Within a month, idle wizards from the entire northwest, north, and west were attracted to Dolai.

Shocking, shocking, an unprecedented alchemy method was presented in front of everyone, and almost all alchemists were extremely shocked.

Alchemy can be so fast and can be played in this way. It's really eye-opening.

The term distraction manipulation slowly spread among alchemists, gradually taking root and becoming a very common term.

Time passed slowly, and soon it was March. The weather in the north began to warm up, some grasses and trees had begun to sprout, and spring was about to come.

At this time, Dole had already returned to the Albis Mountains, preparing to upgrade the Turin Bone Tower first.

The seventh-level Turin Bone Tower can produce Turin Bone Fire, which is a very powerful corrosive flame. It is only suitable for destruction and not for refining. However, its power is enormous and it combines several rules. So far, Dolai has not been able to understand the rules contained therein and can only rely on wizard formations to use it, but it is already very powerful.

The eighth-level Turin Bone Tower can produce a kind of fire called Turin Demon Fire, which is a more evil fire than the Turin Bone Fire. It can burn everything in the world. As long as it is attached to it, it is like a maggot on the tarsal bone, which cannot be shaken off and will be burned to ashes.

The biggest feature of the Turin Demon Fire is that it has a slow flying speed, but a very strong adhesion ability. If there is no specifically targeted magic, it will continue to burn until all the matter is burned. This is its most terrifying existence.

Dolai has studied many of the magic patterns clearly, but has not actually made them. He will make them after finishing the wizard tower this time. What he fears most is that the old black dragon will be eroded by nightmares, so he even made a warning for this reason.

The old black dragon is very cautious, but he is just a magical beast after all. He lacks wisdom and vigilance. He is too worrying and is simply a time bomb.

The reason why he was so anxious a few days ago was that when he was refining the wizard tower, news came from the northwest that eight levels of the northwestern countries were eroded by nightmares. The two sides started a war and finally destroyed a large area. This was what made Dolai feel most urgent.

Although this news has not been officially leaked, people who should know it will still know it, such as Duolai, the northwest security officer of the Glory Empire. If there is really an eighth-level monster being invaded in the northwest, he will be the first to suffer.

This was almost beyond doubt. The Nightmare Ancestor now hated him to the core. The two had fought each other more than a dozen times in the air. It could be said that they had already regarded each other as their mortal enemy. They would fight to the death whenever they met, without any mercy at all.

…

Dolai did not tell anyone about his refining of the Turin Bone Tower, and he quietly advanced in the Albis Mountains.

Just as Dolai was preparing to refine it, a consciousness quietly contacted him.

This consciousness was very deep, grand and broad. Dolai felt an extremely strong darkness.

Old black dragon.

Dole stopped what he was doing, appeared next to the Albis Mountains, and looked into the depths of the Beiyuan Mountains.

As he went further out, the consciousness Dolai felt became stronger and stronger. In the midst of it, Dolai also felt a need for help.

Has Old Black Dragon been tricked?

At this moment, that consciousness suddenly disappeared, and Dolai's heart suddenly shuddered.

He flew towards the mountains almost without thinking.

With Dolai's current size, he naturally could not hide from the other level seven monsters in the Albis Mountains. As soon as he entered the Beiyuan Mountains area, the first one to jump out and respond was the dragon bat.

The dragon bat spread its wings and spread its power, almost covering the entire mountain. Seeing Duolai flying towards the mountain, he immediately jumped out to provoke him.

"Damn human, how dare you cross the line." At this time, Longfu saw that Duolai ignored him and went straight to the central area.
