Junior Uncle is too cunning.

After all, it's hard for anyone to accept being surpassed by their former junior brother; even immortals are human!

All sorts of top-grade immortal materials are being poured into it for free. If other weapon refiners saw this, they would probably be green with envy.

With the last piece of immortal material fused into the Immortal Slayer Spear, the second step of refining was finally completed. Seeing the Yin energy that was already starting to emanate, Chen Fusheng hurriedly swallowed the Spirit Recovery Pill in his mouth, quickly recovered, and then activated his magic power to the fullest extent. It was as if an invisible hand grabbed the Yin energy and forcefully stuffed it into the Immortal Slayer Spear.

If he were to refine other innate spiritual treasures, or even mid-grade innate spiritual treasures that he had never refined before, Chen Fusheng's cultivation level and the magical power within his body would be sufficient.

However, this time it's not simply about refining a new innate spiritual treasure. Instead, it's about refining the low-grade innate spiritual treasure, the Immortal-Slaying Spear, and then upgrading its grade. This is much more difficult than simply refining a new innate spiritual treasure.

The Yin energy seemed somewhat unwilling, like a playful child who was just released and was confused. After a while, it didn't want to go back. After all, it was still restrained inside the Immortal-Slaying Spear, and it couldn't be as comfortable as it was outside.

Chen Fusheng increased his magical power again, pressing down hard on the Yin Sha Qi. Moreover, he was now using the fire attribute magic power from the Five Elements Dao. After all, no matter how powerful the Yin Sha Qi was, it was still a dark thing, and it would be restrained by attributes such as fire or lightning.

This is why the Immortal Slayer Spear was able to refine Yin Qi even at its Acquired Rank. It was because the Immortal Slayer Spear directly chose to advance during the refining process, which attracted a lightning tribulation. The Yin Qi was suppressed and could only choose the Immortal Slayer Spear as a hiding place.

Chen Fusheng cultivates the Five Elements Dao of the Primordial Chaos, which is ranked among the top Daos. Among them, the Fire Dao is an extremely powerful Dao.

Using the power of the innate fire element to activate the yin energy, although not as powerful as lightning tribulation, is still highly targeted compared to other attributes.

Although the Yin energy seemed somewhat reluctant, it was still forcefully absorbed by Chen Fusheng.

As soon as the Yin energy merged in, the Immortal-Slaying Spear, which was just dark red, instantly turned completely black. The Yin energy surrounded it, making it look extremely fierce.

The Nirvana Sacred Flame was summoned again by Chen Fusheng and burned fiercely towards the Immortal-Slaying Spear. This time, the Immortal-Slaying Spear seemed unusually calm, as if nothing had changed. However, upon closer inspection, one could see that the Yin energy on the Immortal-Slaying Spear was slowly dissipating, not disappearing, but rather merging into its body.

As the Yin energy continued to merge, the power of the Immortal-Slaying Spear grew stronger and stronger. The Immortal-Slaying Spear, which was already at the peak of the low-grade innate spiritual treasure, quickly crossed the threshold between low-grade and middle-grade and advanced to the middle-grade innate spiritual treasure. Moreover, this trend had not stopped and was still climbing.

Chen Fusheng breathed a sigh of relief, suppressing his excitement, and intensified the Nirvana Sacred Flame. He wanted to see if the Immortal-Slaying Spear could break through the middle-grade realm and advance to a high-grade innate spiritual treasure.

Time passed slowly, and before anyone knew it, Chen Fusheng put away the Nirvana Sacred Flame. A hint of disappointment appeared in his eyes. In the end, the Immortal Slayer Spear failed to break through to the level of a high-grade innate spiritual treasure and was stuck at the threshold of the peak of a mid-grade innate spiritual treasure.

He slowly put away the Immortal-Slaying Spear and returned it to his dantian to nurture it. Although the Immortal-Slaying Spear ultimately failed to advance to a high-grade innate spiritual treasure, through this refining process, Chen Fusheng had gained a clear understanding of the refining process of mid-grade and even high-grade innate spiritual treasures.

Chen Fusheng took out the Six-Tone Spirit Sword again, but after thinking for a moment, he put it back into his body. Although the Six-Tone Spirit Sword was stronger than the Immortal-Slaying Spear, in terms of potential, the Immortal-Slaying Spear could be said to be far superior to the Six-Tone Spirit Sword.

Moreover, the Immortal-Slaying Spear can be said to be his first innate spiritual treasure, and it has been with him for the second longest time after the wine gourd, which is why Chen Fusheng spent so much effort to improve it.

He originally planned to reforge the Six-Tone Spirit Sword, but now that he's familiar with the forging process of mid-grade and even high-grade innate spiritual treasures, there's no need to spend too much effort and time improving it.

Moreover, Chen Fusheng planned to use the Six-Tone Bamboo to reforge a new innate spiritual treasure. Although the reforged Immortal-Slaying Spear had reached the level of a mid-grade innate spiritual treasure, he was not yet a mid-grade weapon-refining master. Just like when he first forged the Immortal-Slaying Spear, it was mostly due to the use of Yin Sha Qi to advance its level.

After becoming a disciple of Yuanshi Tianzun and forging his first innate spiritual treasure, the Six-Tone Spiritual Sword, he truly broke through and advanced to become a master weapon refiner.

He took out a section of Six-Tone Bamboo, which Chen Fusheng had specially selected from the bamboo forest in front of his door. Its grade had reached the peak of the middle grade, and with his strength, it was enough to refine a middle-grade innate spiritual treasure, and even a high-grade innate spiritual treasure was not impossible.

Taking out the prepared celestial ingredients, Chen Fusheng first used the Nirvana Sacred Fire to scorch the Six-Tone Mystic Bamboo in his hand, rapidly restoring his internal magical power as he burned it.

Refining artifacts is a technical skill, but it also requires a very high level of magical power. This is why many people can only be artifact refiners before reaching the Celestial Immortal level, refining some mortal-level spiritual artifacts. Apart from a few geniuses, very few people can break through this barrier.

Back then, Chen Fusheng also broke through to become a weapon-refining master when he was in the Dao Integration stage. However, he also relied on the earth fire power of the weapon-refining peak of the Lingbao Sect. Otherwise, even if he had a lot of spirit stones to support him, he would not have been able to advance to the weapon-refining master in the mortal realm.

As for breaking through to the Grandmaster level of weapon crafting, one needs at least the strength of a Great Luo Golden Immortal. However, there are very few people who can reach the level of a top-grade weapon crafting master at the Golden Immortal level. Even those who break through to the Great Luo Golden Immortal level are not many who can reach this level.

The Chan Sect is considered a major sect for weapon crafting, especially with a sage who is skilled in weapon crafting. It can be said that everyone there can craft weapons, and there are quite a few weapon crafting masters. However, the number of people who can reach the highest level of weapon crafting can be counted on one hand, and there are only two weapon crafting grandmasters: Chen Fusheng and Yun Zhongzi.

It took Chen Fusheng three years just to nurture the Six-Tone Bamboo with the Nirvana Sacred Fire. Fortunately, the nurturing did not require much magical power, and Chen Fusheng finally managed to restore his magical power to eight levels before the formal refining.

His expression tightened, and the spiritual energy within his body circulated rapidly. The Nirvana Sacred Flame, driven by his magic power, surged forward quickly. The Six-Tone Bamboo, which had been nurtured for three years, softened rapidly and slowly formed a ruler under Chen Fusheng's control.

This time, Chen Fusheng doesn't plan to forge a spirit sword. He's getting a bit tired of using spirit swords all the time. This time, he plans to forge a ruler, intending to measure himself and constantly monitor whether his Dao Heart remains unchanged from its original intention.

Deeper than that, Chen Fusheng also harbored a ambition: to see if he could venture into the primordial world with the ruler in his hand.

Chen Fusheng used to be very cunning, and he knew it himself. Sometimes he was even worse than his clone Li Shundao. However, he felt that under the circumstances at the time, his choice was the right one.

At that time, he himself was not very strong. Although he had the Lingbao Sect as his backer, he was only slightly stronger than some independent cultivators.

Therefore, Chen Fusheng was very aware of his own past. It's okay to be a little cowardly when you're weak. After all, if you're not strong enough, how can you be so arrogant and domineering? Chen Fusheng really doesn't know if he would be the same person he is now.

Now it's different. He has cultivated to the Three Flowers Gathering at the Top realm, and has reached the Great Luo Golden Immortal perfection. The next step is the path to the Saint realm. He has gained the ability to protect himself. So, if he is still as careful and cautious as before, it will not be conducive to his nature and will affect his heart of the Great Dao. This time, the refining of the ruler is a change that Chen Fusheng has made for himself.
