Of course, Bai Xiaowen knew how strong the so-called "secondary demon king", that is, the demon of the high-level king-level template, was.

Placed on a medium and low difficulty plane, the king-level template can already be used as the general boss of the plane world, such as the Black Sky Sect Master of the Shao positioning plane, Temujin, and so on.

At that time, in order to assassinate a Temujin, Bai Xiaowen tried his best to create a siege situation, but it still took a lot of effort to kill Temujin.

Now he had to face a high-level king-level demon, who was three points stronger than Temujin considering his rank.

And the environment is not friendly, this is a world where demons dominate, and there are still a few god-level demons staring at it, it is difficult to plan a siege with confidence like Shao Cheng.

"I certainly wouldn't underestimate the power of the Calamity Demon King. ”

Bai Xiaowen said to the witch Kai Luowen, "In order to fight against the calamity for a long time, I plan to open the dimensional teleportation circle and connect my world. This requires your help. ”

"Dimensional Teleportation Circle?" Both the witch and Hurlbut were a little puzzled.

Bai Xiaowen immediately explained the necessity, this time he came to the Dark Age plane, and it was impossible for him to stay for a long time. And next time you want to come over, it's not so easy, there is a dimensional teleportation circle, which can connect the two worlds, and you can fight for a long time and slowly look for opportunities.

Hurlbut could understand, nodded and said, "If you want to kill a demon king, it is indeed a long and difficult task, and I will assist you in activating the teleportation array." ”

The witch Kai Luowen hesitated slightly.

"Do you have any concerns?" Bai Xiaowen's eyes narrowed slightly.

"No," the witch Kellowen whispered, "I hope it's the right decision." ”

"Of course, I promise. Bai Xiaowen smiled.

......

The teleportation array, also known as the "resonance teleportation array", is also a question of where it is set up.

The current time does not allow, and Bai Xiaowen does not have the energy to find a feng shui treasure place where spiritual power gathers, so he can only set up a formation that relies on spiritual crystals as a power to operate. The disadvantage of such a resonance circle is that it is expensive to operate.

However, Bai Xiaowen didn't plan to summon the territorial army into the Dark Age, just as a backhand, and it was acceptable to be a little more expensive.

Hurlbut's original proposal was to be set up in Utu Town, but Bai Xiaowen vetoed it.

Later, Hurlbut mentions a location, a hidden crypt north of the town of Utu.

In this way, Bai Xiaowen established a resonance teleportation formation with the help of Hurlbut, the witch Kai Luowen, and the other two leader-level militia captains.

The White Phoenix Collar and the Dark Age Plane have officially been connected.

Bai Xiaowen set some permission conditions as usual, the most important of which was that the creatures of the Dark Age Plane could not use the Resonance Teleportation Array without Bai Xiaowen's permission.

This is also for the safety of the white stone collar.

After doing this step, Bai Xiaowen solved his worries. For the time being, he was not in a hurry to do the side quest of the Divine Descent, or to complete the other goal of this trip-to solve the problem of the source of Mengchuan's demon army, but to bury his head in cultivation and start cultivating.

After all, Bai Xiaowen was only level 15, and his level limited the strength level of the Three Heavenly Kings and the undead servants under his command. In this Dark Age plane, the encounters are basically seventeen or eighteen-level high-level monsters, with a difference of more than two levels, and they are very disadvantaged in terms of attributes and spiritual power.

Now, Bai Xiaowen already has two extremely high-quality light balls in his hands - one is the "Epic 4A-level" light ball of the [Eagle Fall] mission, and the other is the "Divine Descent 6C-level" light ball of the [Savior's Proof] mission.

These two extremely high-quality light balls have never been seen by many evolutionaries in their lifetimes.

Bai Xiaowen plans to use one to see if he can touch the threshold of upgrading.

As for the witch Kai Luowen, she would not urge Bai Xiaowen to kill the Calamity Demon King.

In fact, in the perception of the aborigines, to defeat a demon king, it must be fully prepared, and it will take a year or even years of energy to complete. The Evolutionary's rush to achieve quick results and always try to complete the task within a month or two is incomprehensible to the natives.

Therefore, Bai Xiaowen's temporary cultivation and enhancement of strength, the witch Kai Luowen and the chief instructor Hurlbut both expressed their understanding and support.

In order to keep Bai Xiaowen from being expelled, Hurlbut also had an argument with Mayor Kelly. As on the previous occasion, Mayor Kelly and his followers could only shout two empty slogans in front of a well-trained and relatively powerful militia, and then retreated.

Bai Xiaowen was cultivating in the spirit hut, and he directly used up the "Epic 4A" Perception Light Ball.

Of course, it is still used in the "Taigong Art of War" - although Bai Xiaowen knows the importance of the "Taixu Sutra", but the "Taigong Art of War" is related to his professional level, and his professional level is related to the level of the Three Heavenly Kings and the undead servants under his command, which is really very important.

This time, the feeling was even stronger, and when I read the middle part of "The Art of War", one after another feelings emerged like a fountain, as if there was a group of profound cultivators, taking turns to tell Bai Xiaowen's ears about the truth of cultivation.

With Bai Xiaowen's understanding, he had to retreat for ten days to digest the insights gained this time.

He is like a college entrance examination student, who is indoctrinated by a group of teachers in turns, and memorizes things full of things in his head. After the next ten days of "self-study", I gradually accepted and comprehended these new knowledge.

And after comprehending it almost completely, Bai Xiaowen's physical body also produced a strange sense of hunger and thirst and emptiness. Don't get me wrong, it's not that Xiao Xiaowen is restless, but that the body has an extreme thirst for external spiritual energy, which is a physical change caused by the ascension of the realm of perception.

Bai Xiaowen spent another ten days absorbing spirit crystals and consolidating the realm. Although his physical fitness panel did not improve immediately, Bai Xiaowen could feel the faint existence of a bottleneck and a layer of diaphragm.

"A month passed. The epic high-level light ball is indeed powerful, and not long after I was promoted to level 15, I felt the bottleneck of level 16 again. ”

Bai Xiaowen looked inward and "looked" at another god-level comprehension light ball.

However, after hesitation, Bai Xiaowen still didn't use it immediately.

According to the experience of being promoted to level 15 last time, Bai Xiaowen had to go through a great battle of the Domination Department before he could be promoted to level 16.

Otherwise, it will be difficult to complete the breakthrough just by relying on the accumulation of the light ball of perception. If this precious god-level ball of light was consumed and it didn't break through, it would be an unforgivable waste.

Just like a student who has learned a lot of new knowledge, he always has to go through the examination room, do a few sets of papers to practice, and practice to prove it, so that he can really master and use it.
