Tyler returned and found Alfred and Erena standing in front of the door.
"Have you packed everything?"
Both nodded.
Alfred spoke.
"Young Master, your ride has arrived. We can move now."
Tyler nodded. He did see a carriage outside their boundary. Three of them went to the carriage.
It was a four-wheeled carriage with two black horses on the front. Tyler had noticed something peculiar about this world.
While it wasn't ancient, it had its own way of development. For example, they had built a steam engine a long time ago.
But instead of focusing on building an internal combustion engine, they simply chose to use the horses.
These horses could travel faster than any of the cars. If they were to use a certain ranked horse, it could even move faster than most commercial planes.
Then, if someone wanted to go faster, they could visit bigger cities where a teleportation module could be found.
Those teleportation modules could be anything from an array, a supernatural ability, or a talisman.
So instead of chasing the development of science, the people of the cultivation world used their advantage to develop a highly advanced civilization.
The driver opened the carriage's door, and three of them walked in.
The inside of the carriage was well-lighted and well-ventilated. There were four seats in total and two beds.
Two beds were next to each other while four sofas were placed on opposite sides, with two on each side.
When entering from the door, there was a good enough space to move around. Tyler went to bed while Erena and Alfred sat on the sofa.
Tyler didn't plan to sleep but continued his cultivation. He took out the box from his spatial ring and opened it.
When Alfred saw the stone, he instantly recognized it. A look of admiration appeared on his face as he stared at Tyler.
On the other hand, Erena looked confused as she turned towards Alfred and asked.
"What is it? It feels so close to me."
"That's Yin Essence Stone."
Alfred answered in a low voice.
"What? Why does Young Master…"
Erena also realized why her Young Master needed it, but her face quickly turned bright red.
She lowered her head and muttered.
"Young Master could've simply asked for my help. He didn't need to spend money on that thing."
Alfred shook his head, ignoring her words. When his Master asked him to get a woman near Tyler as his maid, he already understood his Master's intentions.
Especially after knowing the conditions he had set. But Alfred had watched her grow for nine years, almost ten if he counted a year he spent watching her.
Naturally, he saw Erena as his daughter. He wasn't married, so he took care of her as a daughter.
He didn't mind her being Tyler's maid, but he didn't want to harm her. It was clear that his Master intended to harm her.
But it seemed like that was more of a choice. Tyler chose not to harm her by using other resources.
On the other hand, Erena, biting her lips, staring at Tyler, didn't realize she had dodged a bullet.
The Yin Essence from the stone started pouring into Tyler's body as he activated his technique.
His body also started producing Yang Essence, merging it with the Yin Essence. At the same time, it continued absorbing the spirit energy from the surroundings.
Upon refining mana, he would release the Yin-Yang Essence into his mana and start the process of evolution.
It wasn't something he could control as he was simply letting the process continue. At the same time, Tyler noticed something strange.
He felt weaker. His body grew a bit paler, and his blood became thinner. He didn't know what was going on, but Alfred and Erena started panicking.
Alfred immediately realized what was happening.
'But didn't those who awakened the Dual Cultivation Technique often have a special physique to recover their Yang Essence?'
'Why doesn't Young Master have it? No, I need to buy more resources to replenish his Yang Essence and tell him not to cultivate till then.'
'But I can't stop him now. A cultivation is a critical process. Stopping him now would only make the situation worse.'
'Damn it!'
Alfred clenched his fist and stayed on his sofa. Erena wanted to stop him, but seeing Alfred's expression, she also realized the problem.
Facing this process, she had no choice but to sit down.
'Damn it! This tower is harming me. Fuck!'
Tyler was angry, no, he was beyond angry. Just when he thought he could finally cultivate fast, his situation made him realize he wasn't meant for dual cultivation.
Dual Cultivation required Yin and Yang Essence. Once used, it would take them quite a while to recover.
Yang Essence could help women recover their Yin Essence, but Yin Essence couldn't do the same.
Men with the Dual Cultivation Technique often had a physique with strong Yang Essence recovery.
It was clear that he didn't have such a physique. But this tower chose him...
'No, it didn't choose me. I understand now. If it had truly chosen me, it wouldn't have given me a technique like this.'
'A tower that could hold nine fairies with incredible power, how could it not have another technique suited for me?'
'It's clear that it didn't choose me, but rather my soul chose it.'
At this moment, something clicked in.
Tyler realized what was going on. His soul wasn't born from his mother. Instead, it appeared in this world and merged with an unborn child.
While it appeared in this world, it should've somehow merged with this tower; maybe it forcefully merged with the tower.
Because of this, Tower had no choice but to accept him as its new owner, but it was clear that he wasn't suited to be its new owner.
So, the question was. Could it kill him?
He believed that was not the case. The tower couldn't kill him directly or even harm him, but it could indirectly make him suffer.
For example, he had a second Inherited Technique.
[Void Creation Technique]
This technique was overpowered. To some extent, his second technique was much more powerful than the dual cultivation technique.
But it also had a great restriction. To practice this technique, he needed to awaken the Supreme Void Body.
There was one problem. His physique wasn't Supreme Void Body. At least, it wasn't at that level, whatever that level was.
Inherited Technique was a cumulation of bloodline, physique, soul, and mentality. That meant he did have a physique related to Void.
It wasn't Supreme Void Body, but the requirement for his technique was this physique since this tower evolved it.
Of course, he could be wrong. This was just an assumption. It could be a test from the tower.
It could also have no relation to the tower. After all, Inherited Technique was connected to the soul.
And, his soul did come to this world, tearing the space or whatever.
The reason didn't matter. What mattered was a solution.
Currently, he couldn't practice the Void Creation Technique. His dual cultivation technique was not only harmful to others but also to himself.
In other words, he was stuck in a situation where he could neither retreat nor advance.
But his sharp mind immediately came to a conclusion.
'What would you do if you didn't want to complete a complex and long mathematical problem every single time?'
'You use a calculator.'
That's exactly the solution he thought.
Since he needed Yin Essence to speed up his cultivation process and he couldn't spend days, if not weeks, to recover his Yang Essence, he could just use resources.
There should be items that could improve his Yang Essence. Maybe there was a certain resource that could improve or give him a Yang-related physique.
It was all possible.
With his intensive knowledge of the cultivation world, he knew these things existed. They were just out of his reach.
But not for long. Even if they were not present, his parents were always helping him.
With the gold coin, he could easily buy a resource related to Yang Essence.
Thinking about it, he calmed his heart and focused on cultivation. Even if it was draining of Yang Essence, he continued his cultivation non-stop.
Two days later;
He opened his eyes. The stone in his hand was still brightly glowing with white light, but his face was paler than before.
He seemed to have lost a lot of Yang Essence to the point that he needed to take a rest for a whole week.
But on the bright side, his cultivation speed had tripled. That meant in just two days, he had cultivated mana worth six days with his talent.
So, this technique did manage to double his cultivation speed, and with high-level Yin Essence, that speed improved even further.
C-Grade talent could cultivate twice as fast as D-Grade, but B-Grade could cultivate four times faster.
So, his cultivation was three times faster than normal D-Grade, placing his speed between C and B Grade.
