"Hu…" Anna opened her eyes, feeling a bit relaxed. She looked at her hand. The outer layer was as thin as her skin, and the energy was contained extremely well.
However, because only her hand had this outer layer, the excess energy had to flow out from her arm. It would be more troublesome to wrap her entire body with this.
"Congratulations." Old Ru smiled. He glanced at the sky and continued, "You only used six hours to reach that level. I should say I'm impressed."
"It's quite hard." Anna shook her head helplessly. "Still, what's the benefit of this ability? I have some guesses, but I'm not sure yet."
Old Ru smiled and raised four fingers. "This control has four benefits. The first is…"
Old Ru channeled his energy into his hand. "As you saw earlier, depending on how much energy we put into this, the thin layer could become a plate that is harder than steel. And the burst of energy, once it's popped out, will also be beneficial for an attack."
"Indeed." Anna nodded with a serious expression.
"As for the second benefit, try to channel your energy again to your arm, but this time starting from your Spiritual Energy Reserve."
Anna tilted her head in confusion and followed his instruction. The moment she poured the Spiritual Energy into her arm, the flow was so smooth that she couldn't believe it. "Huh? This is…"
"This is the benefit. Once you get used to it, your body, your instinct, and your mind will get used to the smoother flow by utilizing that control. This way, you can use your power more efficiently since you can control the amount of Spiritual Energy you want to use and quicker due to the smoother flow."
Anna sucked a cold breath. These two alone were enough to make this technique a national treasure. This kind of mastery would allow them to fight against a Spirit Grandmaster in the future.
However, Old Ru mentioned there were a total of four purposes.
He raised three fingers. "The third is related to your training. Once you get used to it, I don't think I have to explain what you will be able to do, right?"
Anna nodded furiously. "Yes. Once we get used to this, we will be able to adapt to our surroundings and have a better connection with the things around us."
"That's not all…" Old Ru closed his eyes for a second. His Spiritual Energy started to come out, interacting with the environment. "There are five ants next to your right shoe."
"Huh?" Anna widened her eyes and checked. As he said, she noticed ants, but there were only four ants. But two seconds later, she saw an ant crawling from beneath the grass, revealing its appearance. "What? How can you…"
"Everything in this world has its own frequency of Spiritual Energy. I'm simply spreading my Spiritual Energy and trying to make a connection with them. Once you get used to it, you can find hidden enemies or any details from your surroundings. And if you continue, you should be able to extend it from your body to a certain distance."
Anna fell silent, astounded by the claim. However, it was still within her reason, making her realize that this ability was much more terrifying than she originally thought.
"Then, what about the last one?"
Old Ru smiled. Suddenly, a few lines began to appear from his chest and gradually spread all over his body. The lines were glowing in green.
Her instinct was telling her that this was dangerous, but the lines didn't exude anything that could be deemed as dangerous. However, Noel didn't show this in the previous life. Instead, it was Old Ru's grandson.
Considering Old Ru told her that it was one of the benefits, it seemed that Noel either purposely hid this power or simply hadn't reached this level yet.
"Bloodline Release. This is the ultimate stage of what you're learning right now. You are basically stimulating your Spirit Seal and creating an artificial Spirit Link."
"You can consider that you are directly borrowing the Spirit's power through this artificial Spirit Link. Since you are already aware of True Spirit Body, you can think of this as a downgraded version of the True Spirit Body."
"The power might be a third of the True Spirit Body, but there is one big advantage of this ability. It doesn't have any side effects like the True Spirit Body."
"!!!" Anna's body trembled. She obviously knew the True Spirit Body. The True Spirit Body forcefully stimulated the human's body and turned their bodies into that of a Spirit. This way they could fully utilize the power, allowing them to release power beyond human limits.
The power didn't have to be questioned anymore as it allowed Dimitri to challenge a Spirit Transcendence Level Expert.
If what Old Ru said was true, they could create an Artificial True Spirit Body. The effect might be lower, but there was no side effect.
When one used the True Spirit Body, their links with the spirit would be ruined, causing them to be unable to use the spirit for a period of time. They had to endure the excruciating pain of mending those links as well.
So, this ability could only be described as god-like. It was no wonder why his grandson used this ability a lot.
"I would never think such a thing is possible." Anna shook her head helplessly.
"So, how is it? I think this makes your trip here worth it, right?"
"Indeed. But by telling us about this powerful ability, aren't you afraid that we'll be giving these to human kingdoms to fight against your kingdom?"
Old Ru shook his head. "I don't really mind to be honest. Besides, there are two big limitations to this ability. First, you need at least 80% of the Conversion Rate. Lower than that, your link with your spirit is simply too low to stimulate this power. In fact, you might not be able to create an outer layer."
Anna nodded in agreement. Even with her conversion rate, previous life knowledge, and her experience, it was hard to even maintain it on her hand, so she understood the difficulty. "Then, what about the second limit?"
