After flying for over an hour, Lu Yu finally returned to Blue Ocean City, and the spiritual power consumed along the way was simply terrifying.

However, the sea of Spiritual Qi within the Eye of the Sea hadn't changed much.

Just when he got home, Lu Yu received a phone call from Fei Yuqing.

"Lu Yu, where did you just go? Why does the GPS show you went abroad?" Fei Yuqing asked.

He was afraid Lu Yu was doing something important, but when he saw Lu Yu's GPS show him back in Blue Ocean City and stopping there, he called to inquire.

"I accidentally flew abroad. Is there something you need?" Lu Yu replied.

Fei Yuqing was a bit speechless. In less than three hours, Lu Yu covered a distance of over six thousand kilometers; could this really be accidental?

"No, just calling to check and see if you went abroad for something important."

"If there's nothing else, I'll hang up now," said Lu Yu, sitting down to rest.

Before Fei Yuqing could respond, Lu Yu hung up the phone.

Fei Yuqing, listening to the disconnection tone on the phone, felt a bit helpless.

Leaning on the sofa, Lu Yu's mind recalled the Holy Light cultivation method that Donald had given him.

The Holy Light cultivation method was very simple—just meditate on a rune symbolizing Holy Light in the mind, continuously meditating on the rune to deepen the connection with it, until establishing contact with a powerful existence on the other side of the rune, to receive the seed of Holy Light and gain its power.

And what Lu Yu had to offer was just his faith. As long as he believed in that powerful existence, he could gain the power of the Holy Light.

Faith did not require regular prayers; it only required believing in one's heart that the other party existed.

It seemed very easy to gain the power of the Holy Light; believing in something that felt existent wasn't too difficult.

Lu Yu closed his eyes, emptying his mind, leaving only the Holy Light rune Donald had told him about.

Tracing the path of the Holy Light rune over and over, the rune's appearance became clearer in his mind, but Lu Yu couldn't feel the so-called will of the God of Light.

Perhaps it was because this was reality, and the power of the God of Light couldn't permeate through.

Lu Yu stopped meditating, closed the doors and windows, returned to his bedroom, and entered the game.

Back in the world of divine martial arts, back in the little bamboo house, Lu Yu's injuries were mostly healed thanks to the Life Bone Transformation Pill, and although he couldn't exert full power, at least he could move.

Focusing his mind for a moment, he found that the Holy Light rune he had traced in reality was still in his mind, and because it entered the divine martial world, a slight change had occurred, as a trace of Holy Light's aura emitted from the rune.

If Lu Yu meditated deeply a few more times, that power could descend into his mind through the rune.

Lu Yu didn't plan to start meditating immediately. Although he wanted to obtain divine power, he didn't want to worship so-called deities.

I intend to take the power, sorry! I only believe in myself.

Deities are nothing but beings with immense power, Lu Yu firmly believed.

"The Blood Burning Secret Technique's power increase is too vast and uncontrollable; I need to enhance my mental strength to control the berserk power and maintain consciousness,"

Lu Yu thought, glancing at the "Divine Combat Technique" on the attribute panel.

He had already thought of a way to counter the loss of sanity caused by the Blood Burning Secret Technique during his downtime while contemplating life.

If the power is too strong to control, then enhance the control, meaning increase mental strength and strengthen the soul.

Consume 100,000 experience points to upgrade the Divine Combat Technique.

[After painstaking training, the Divine Combat Technique has been raised to the seventh level, mental strength increased]

With the upgrade of the Divine Combat Technique, Lu Yu felt his mind clearer, the fire in his right eye contracting, its brightness diminishing, not as glaring anymore.

After the upgrade, as Lu Yu was about to close the attribute panel, he unexpectedly found that the Divine Combat Technique could be further upgraded. Feeling curious, he wondered since before he logged off, there were only 160,000 experience points left, how could it still be upgraded?

Scrolling down, he found there were still 120,000 experience points left on the panel, with an additional 60,000 experience points; he didn't know where they came from.

No matter where the experience points came from, since he could upgrade, he continued to do so.

Consuming another 100,000 experience points, he raised the Divine Combat Technique to the eighth level, increasing mental strength and control over power.

Lu Yu estimated that by raising the Divine Combat Technique to the tenth level, he would likely be able to maintain consciousness when activating the Blood Burning Secret Technique.

However, to be safe, Lu Yu planned to raise the Divine Combat Technique to the fifteenth level.

By raising the Divine Combat Technique by two levels, Lu Yu felt his mental strength increase by sixty percent. The higher the level of the Divine Combat Technique, the greater the enhancement in mental strength; raising it to the tenth level at least doubled his previous mental strength.

When the Divine Combat Technique reached the fifteenth level, his mental strength would certainly be four to five times stronger than before, which would be just enough to match the fivefold power increase of the Blood Burning Secret Technique.

If a fivefold power increase was uncontrollable, then by raising mental strength fivefold, it could be controlled.

After upgrading the Divine Combat Technique and increasing his mental strength, Lu Yu had also recovered more than half of the mental strength he had consumed with the rainbow-like flight technique. Though his injuries had not fully healed, he could hardly resist the urge to go earn more experience points.

With the rainbow-like flight technique, he once again arrived at the Sky-reaching Tower. Previously, Lu Yu exited the tower because his mental strength was nearly depleted.

Returning to the ninetieth floor, Lu Yu flew outside the safe zone, slowly circling the ninetieth floor, and by the time he returned to the starting point, he had thousands of monsters trailing behind him.
