The Witcher: Son of the Planes.

Less than half a day after Colin and his companions left, a team of knights exuding an even more powerful aura arrived at the scene where Colin had captured the headless knight. The leader looked even more powerful, especially the head made of energy, whose appearance in life could still be vaguely seen.

"Dura's breath disappeared from here. It didn't take long, probably less than half a day." said the leading terror knight after the investigation.

"Sir, could it be that another lord is attacking us?"

"Well, no, it feels a bit like a stranger. Let's go back. Dura can't be found. I will report to the lord."

The Terror Knight was not willing to bother himself with such an obviously thankless task, so he turned his horse around and led his headless knight back.

And our Colin had been urging Charles to go faster half a day ago, but the other party was too lazy to take care of it.

It cannot be said that Colin is timid and fearful. Being in a foreign world without any support, he will surely follow in the footsteps of his predecessors if he is not careful.

Colin and his team stopped only after returning to the place where they first encountered the group of skeleton creatures and were able to activate the teleportation stone.

From the memory of the Headless Knight Dura, Colin already had a general understanding of the Skeleton Plane. Although the upper-level combat power was unclear, based on the information now known, the Della family simply did not have the strength to conquer this plane. Even Listan and Griman would probably find it difficult.

The mission seems to have been completed now, and it has taken less than half a year in total. However, Colin does not want to go back just like that. The negative energy here is very abundant, which will be very helpful for the promotion of his subordinate Rose. He wants to wait for Rose to be promoted before returning.

Of course, Colin's idea requires a prerequisite, a stable and safe place.

According to Dura's memory, the area where Colin is currently located was once an ancient battlefield. There is plenty of negative energy here. There are many such ancient battlefields in the entire skeleton plane, all of which are occupied by some large forces because they can continuously produce subordinates and can also be used for cultivation.

The area where Colin is now was once the territory of a bone king. However, due to a war with other lords hundreds of years ago, he had to fall into dormancy, which caused the area to appear disordered.

The place where Colin captured Dura belonged to the territory of another lord, Abaddon the Terror Knight. Although the Bone King had fallen asleep, Lord Abaddon did not want to provoke him and naturally would not invade his side. This was why Colin had been running for so long without seeing the other side chasing him.

Colin didn't know the exact sleeping place of the Bone King, but he felt that as long as there was no major turmoil, this professional who might be at the third level would not be awakened.

Since Rose came to the Skeleton Plane, her recovery and cultivation have been much faster than in the wizarding world. In just half a year, Rose has recovered from the damage caused by the last failed promotion. Both her mental strength and physical condition have reached their peak again.

With the joint efforts of Colin and Rose, they chose an area and forcibly controlled hundreds of skeleton creatures. After the control, they simply arranged daily patrol tasks for them, as long as they were not disturbed by other creatures.

Everything was ready, waiting for Rose to advance, but the two had disagreements over the path after the advancement.

Colin thought that since this place was suitable for advancement and Rose's physical condition had returned to its peak again, why not try to advance to become a formal dark wizard?

Rose's idea was that she had already failed once, and if she failed again, she would never have the chance to advance again, and could only wait for her body functions to gradually age.

Besides, ever since she avenged Jack, she had no attachment to her own body. After all, it was because Armand coveted her beauty that he betrayed her later.

To be honest, Colin didn't want to force Rose to do anything. Since Rose became Helen's maid, she had been very diligent and was responsible for taking care of many things at home. Since Rose didn't want to be a "human" anymore, Colin could only agree in the end.

According to the records in the Lich Training Manual (obtained from Chapter 144), Rose read the manual again and studied all the steps carefully. After confirming that there were no omissions, Rose began her career transformation into a lich. This career transformation of Rose was both a career change and a promotion to a first-level professional, so it was naturally somewhat difficult. However, the rich negative energy here gave Rose great confidence.

There is no better place for advancement than here, not to mention that with the protection of Master Colin, a powerful first-level wizard, the success rate this time should be very high.

The resources that should be provided to Rose had already been provided to her by Helen, but when Rose finally advanced, Colin still expressed his gratitude. The dark flower (obtained in Chapter 137) that had been lying in his space ring for a long time did not cost much money at the beginning, and now it was most appropriate for Rose to use.

Rose has already begun to outline the magic circle. Although Colin is a first-level wizard, he is not as proficient in dark witchcraft as Rose. Rose does not need Colin's help, so Colin naturally stays away from her and just acts as a guard.

The magic circle drawn by Rose has two main functions. One is to absorb the powerful negative energy of the skeleton plane for her use, and the other is to sacrifice one's own life to change jobs.

After outlining the magic circle, Rose began to chant a spell. As the spell ended, a strong light burst out from the magic circle. Colin felt that the negative energy around him became more sticky and rushed towards Rose's position madly.

Luo swallowed the dark flower without hesitation, completely opening his heart to welcome all of this.

Colin involuntarily released the protective shield. He didn't want to absorb the negative energy, but other energy seemed to have been completely squeezed out of this area.

Colin couldn't help but worry about Rose, but seeing that Rose was fine, with the influx of negative energy, Colin discovered that there were some new changes in Rose's body shape.

Rose's skin became paler, like a deathly gray, and her eyes gradually changed from blue to red.

Not only that, from the detection on Earth, it was learned that Rose's body temperature was also constantly dropping. In fact, Colin had already felt the chill from Rose without Earth's reminder.

Then, Colin heard Rose groaning in pain. Colin asked hurriedly, "What's wrong, Rose?" but got no response from Rose.

Then, Colin discovered that Rose's soul seemed a little incomplete. Rose endured the pain and took out a metal box engraved with patterns from the space ring she carried with her. Through some magic, the part of Rose's soul that was separated seemed to have found a home and was absorbed into the metal box by itself.

After a while, Rose's physical data continued to rise, especially her mental strength, which broke through 25 points in one fell swoop. Then this state gradually calmed down, and immediately followed by a cold and emotionless voice, "Master, I have successfully changed my job!"
