Rei started to trained Xiao Wu and Bai Wu as he teleported them back to the lake. Rei had first set up a energy gathering barrier so that Bai Wu could achieve rank 100 faster. Having done his main task, Rei could only wait for Bai Wu to reach rank 100 herself. Xiao Wu on the other hand needed better combat experience as well as reaction time in a fight.
"Xiao Wu, this barrier makes it so that 2 days in here will be 1 day out there." Rei said as he laid down the barrier.
"You'll be fighting against waves and waves of enemies that are modified to be a decent challenge to your level. The seal will also heal you everytime you are about to lose so you don't need to worry. But every time you lose the gravity will increase making it harder so I suggest you stay alive, this training will continue until you defeat all of the levels or I let you out." Rei said as Xiao Wu nodded.
"I can do it, I'll surprise everyone when I return stronger!" Xiao Wu said as Rei smiled.
"Go on I believe in you." Rei said as he sent her into his own constructed space for training.
Rei would occasionally feel the situations on Tang San's side as he was close to death but eventually pulled through. Even if he didn't Rei would have used the seal as a catalyst to heal Tang San from a distance.
Every now and again, Bai Wu would burst out with a colossal amount of energy as she cultivated towards the next rank.
97....98.....99!!!
However, Rei frowned when he saw that she couldn't pass through 99 no matter how she tried.
"Why is that....Bai Wu is essentially immortal thanks to my energy merging with her's, so that means some changes are bound to happen...If I took into account of my own cultivation, I only passed through certain levels because of my law comprehensions....to reach ascendant I had comprehended the law of space....to reach divine ranks I had comprehended the divine essence of space....does that mean Bai Wu needs to comprehend a divine essence to reach rank 100 god?...Rank 100 god's in this plane aren't true divine ranks 1's because they haven't comprehended a divine essence, since Bai Wu's changed due to my energy that means her internal energy structure is now foreign to this world's cultivation whilst still using their system...there are bound to be restrictions as Bai Wu can fight against a rank 100 god easily before as a rank 97." Rei muttered as he looked at Bai Wu cultivating.
"That means she would have to comprehend a law into a divine essence for her to reach rank 100 god/ divine ranks." Rei concluded with a sigh.
"Darling." Rei called out as Bai Wu opened her eyes.
"What is it hubby?"
( ╹◡╹)? She asked curious.
"I know why you can't enter rank 100 god now. Remember how I told you my way of cultivation was different from this world's?" Rei said as Bai Wu nodded.
"Well your internal energy system might have been changed by me as my energy merged with yours. The good thing is that you are now ageless like me and have a much higher power threshold. The bad thing is that it becomes alot harder for you to increase your power. To reach my version of the rank 100 god or Divine Rank 1, you will need to understand a law and evolve that into a divine essence." Rei explained as Bai Wu understood what Rei meant.
"So you mean I can never reach your level until I comprehend a Divine essence?"
(゜-゜)Bai Wu asked.
"Yes." Rei replied as Bai Wu stood up and sat next to Rei.
"Then do you have anything you can recommend for me to comprehend?"
( ˘ ᵕ ˘)She asked leaning on Rei.
"Darling I would suggest you try comprehend both wind and illusions. Wind so that you can increase your speed and attack whilst Illusion so that you can defeat people without confronting them. If illusions fail you can use your comprehension of wind." Rei explained as Bai Wu nodded.
"I can help you with wind since I have comprehended the law of elements. As for illusions...I can only tell you what I know about them." Rei continued as Bai Wu stood up.
"Well let's get started shall we?" Bai Wu said with a smile. Rei also smiled as he used his energy to summon wind.
"Which one first? Wind or Illusions?" Rei asked.
"Let's do both." Bai Wu said with confidence as she sat in a lotus position.
"Fine, I'll set a barrier so that there are winds constantly hitting you. While they're hitting you try to understand what wind is, how it works, how by compressing it you can increase your speed. In the meantime I want you to listen to my voice as I explain illusions." Rei said setting up the barrier.
"Illusions are fundamentally the control over how light tricks our brains. The brain is the centre of control in our bodies so that if it believes there is a threat in front of the body the brain will control you to react to the threat. By controlling what the brain feels and sees, you can form illusions into their consciousness. Using different forms of energy control, you can adjust what is in the surroundings to misguide your enemy. You can make them misjudge how far an attack is, how many attack there are and what sensation their skin is feeling. If you make the brain believe that there are wounds on the arm, it would try to discard and heal the target. So with an immortal enemy that is ageless, you can make them experience their bodies being destroyed and rebuild incapacitating them giving you the chance to attack them...." Rei continued to talk about what he understands about Illusions as Bai Wu listened.
The more Rei talked the deeper he delve into the understanding's of illusions himself. Unknowingly, he had also comprehended Illusions with the help of his Ring of Themis which increases his rate of comprehension.
Months passed as Rei had understood the law of Illusions giving him a mutation in his Eye of Samsara. The mutation allowed for it to act similar to the sharingan as it puts the enemy into a illusion zone. But, unless they have overwhelmingly more power than Rei or if they understood illusions better than him, they won't be able to escape the illusion.
Bai Wu on the other hand had understood the law of wind but only the concept of illusions, while she had been understanding these laws the energy gathering barrier had continuously aged her rings as 7 out of 9 rings had become 1,000,000 year rings.
During the time that Rei had tried to help Bai Wu understand the laws, he could feel Tang San growing stronger as he had returned to the group.
Xiao Wu was still inside the realm facing off against enemies as she was able to fight against rank 70's with her powers having reached the rank of 57.
A few more months passed as Rei saw Bai Wu understand the law of Illusions along with Xiao Wu walking out of the space having defeated all of the enemies.
"Xiao Wu, congratulations."
⊂(・ヮ・⊂)Bai Wu said hugging Xiao Wu.
"Thanks mum, I finally reached rank 61." Xiao Wu replied as Rei smiled from Xiao Wu's improvements.
"I think it's time for us to return, it's been 9 months since we first started and Xiao Wu had gone through 18 months of training." Rei said as Xiao Wu grew excited.
"I can finally see brother again!" She said with a smile.
Rei nodded as he teleported them to where Tang San was.
'Hubby, if you could increase the time ratio why dont you do it so that we can spend more time with Xiao Wu?' Bai Wu asked mentally.
'I've tried to, it stays the same no matter the time difference. If 3 years passed in a space where it would be 6 years outside I would still be taken as I have experienced 3 years passing.' Rei explained as Bai Wu nodded in understanding.
[Time remaining : 8 months]
