As the dazzling lightning gradually shrank, Lei Lin's sword body slowly returned to normal. After swallowing the lightning, it seemed much more agile. When it moved, the color of the lightning became much more brilliant.

Seeing this, Su Rui reached out and took down the thunder scale hanging in front of him.

The Thunder Scale allowed him to manipulate it. The lightning from the sword passed through his palm without leaving any mark, as if it were just a harmless light. But Su Rui knew that this was because he was the master of the Thunder Scale, so he was immune to the lightning. If it were anyone else, even a touch of this earth fire lightning would burn them severely!

Su Rui sat on the cloud bed, holding the Thunder Scale in his hands. He concentrated his energy, pouring the pure Qi within him into the Thunder Scale and began to cultivate it. Previously, due to the urgent situation, he had simply cultivated the Thunder Scale, leaving a trace of Qi within the Thunder Scale sword, a bit like seizing the mountaintop, and paid no attention to the restrictions within the Thunder Scale. When the Thunder Scale was needed in a battle, he basically let it flow freely, without his control.

After his true qi flowed into the sword, he discovered that within the Thunder Scale Sword itself, there were two divine prohibitions blazing with lightning, as well as four remnants of divine prohibitions, like the marks left behind by healed wounds. The presence of these divine prohibitions made the Thunder Scale Sword appear even more mysterious and precious, and also allowed Su Rui to sense its vicissitudes and tenacity.

Su Rui suddenly felt a pang of heartache for Lei Lin. He seemed to see the sword's loneliness and struggle under the scourging of time. Every scar of divine prohibition was a wound inflicted by time, and each wound was a moment of growth. It was like a lone warrior, silently enduring everything, yet never giving up its faith and mission.

At that moment, Su Rui felt a deep reverence for the Thunderscale Sword. Its blade, like a mighty dragon tempered by time and fate, proudly coiled in the long river of time, awaiting the arrival of its destined possessor. Its blade, like a scale baptized by thunder and storm, shimmered with a mysterious light, as if telling the world of its glory and splendor.

It has witnessed countless heroes and legends, and the many stories and memories it carries are all reflected in the remnants of these four divine bans.

"No wonder Master Yu'e once said that it has the potential to return to the True Spirit rank. It turns out that it itself fell from the top level of True Spirit magic weapon!" Su Rui thought to himself.

Generally speaking, after refining Divine Forbidden Elements, a weapon becomes a magical weapon, and refining nine Divine Forbidden Elements can potentially evolve into an acquired treasure. Magical weapons are further divided into different levels. Those with three or fewer Divine Forbidden Elements and the development of spiritual intelligence are generally called Void Spirit Magical Weapons. Magical weapons at this level are like a fetus still in its mother's womb: though not yet fully mature, they already possess limitless potential and possibilities. They have begun to develop a rudimentary consciousness, eager to grow, and they long for the day when they will condense into a true spirit and reveal their own brilliance.

Those with more than three but fewer than six divine prohibitions are called true spirits. At the true spirit level, magical instruments that have developed intelligence are often capable of transforming into living beings. They are like a grown-up youth, possessing their own thoughts and emotions, and possessing their own unique personalities. They can choose their own form and appearance, as well as their own methods and paths of cultivation, based on their preferences and wishes. They are no longer simply magical instruments, but rather beings with flesh, blood, and souls.

Those possessing six or more divine prohibitions are called Yuanling magic weapons. These magic weapons are capable of deriving a variety of powers and can even cultivate independently, without the worry of losing rank. They are like a powerful being who has reached the pinnacle of power, possessing unparalleled strength and wisdom. They can unleash their power at will and continuously improve their realm and strength.

If they could generate innate divine prohibitions and become supreme treasures, they would be able to control the laws and destroy heaven and earth without a problem. They were like humans who had cultivated to become immortals, transcending the scope of magical tools and becoming beings beyond nature. The true spirits of supreme treasures could even be reincarnated, transforming into humans or other creatures, embarking on the path of cultivation.

Lei Lin's True Spirit Magical Treasure was downgraded to a Void Spirit Magical Treasure because he was imprisoned in the ruins of the earth's core for too long. Although he could no longer manifest his True Spirit due to the downgrade, he still maintained the intelligence that a top-level True Spirit Magical Treasure should have. His wisdom was almost the same as that of a human teenager, so he was able to communicate with Su Rui very fluently.

However, Su Rui sat upright on the cloud bed, using all his strength to practice the Qingcheng Heart Method to refine the Thunder Scales. Suddenly, an hour had passed.

The lightning scale in Su Rui's palm suddenly transformed into a streak of lightning, like a nimble dragon. With a sudden roar, it soared through the air and, at astonishing speed, pierced the body of a high-flying hawk. The hawk was instantly engulfed in flames, like fireworks blooming in the night sky. Then, the lightning scale rapidly descended, landing steadily in Su Rui's hand.

The attack just now was performed by Su Rui using the sword technique. The power and speed of this attack were amazing. It was Su Rui and Lei Guang who were in tune with each other and jointly created this feat.

Su Rui opened his eyes, a smile playing on his lips. Confidence and satisfaction gleamed in his eyes. He had finally successfully completed the complete ritual of refining the Thunder Scale.

Thunder Scale was in his hand, flashing with electric light. Su Rui felt Thunder Scale's joy, and he knew that the tacit understanding between them had reached a new level.

Su Rui also understood the method for nurturing the Thunder Scale. As long as he fed it with lightning light at regular intervals, the Thunder Scale would return to the rank of a True Spiritual Treasure. While this method seemed simple, it required constant effort and perseverance. Su Rui believed that as long as he didn't give up, the Thunder Scale would be able to regain its former glory.
