Chapter 165 The Senior's Secret Discovery

Under the moonlight, the depths of Yinfeng Gorge were pitch black.

A cluster of azure flames burned quietly in the strait, bringing a ray of light.

Instead of staying in the room, Su Baichen used illusion magic to create a rocking chair and sat there swaying on the corridor outside.

The rhythmic sound of the rising and falling tides below only made the night seem quieter and more peaceful.

The azure phantom fire danced on the nearby railing pillars, emitting a clear light, but it had no warmth whatsoever.

Illusion Fire is actually a symbol of illusion magic beginning to interfere with reality, and in essence, it is an even more powerful illusion magic technique than the Black Cage.

On Su Baichen's lap, the little fox curled up comfortably, enjoying the peace and tranquility of the moment, feeling that there was no more comfortable time in the world.

A notebook floated in front of Su Baichen, turning its pages on its own every now and then as he read.

Grandmaster Kunyu's notes are very thick, and Su Baichen has only read more than half of them so far.

This grandmaster uncle wrote notes in the form of a diary, which allowed Su Baichen to see his grandmaster uncle's thoughts and evolution in the art of weapon making from beginning to end.

However, he had already determined that he had no talent for crafting, so he could only quickly skip over the related content and did not bother to think about it.

But when the progress was halfway through, Su Baichen suddenly sat up straight with a start.

Because he discovered that his grandmaster Kunyu, who was always alone, had actually discovered and refined a special material in that cave deep in Yinfeng Gorge!

This material is of the Yin nature, possessing an extremely strong ability to attach to Xuan Yin spiritual energy, and can also serve as a carrier of the soul.

Grandmaster Kunyu believed that this material was very suitable for making the main banner of the Ten Thousand Souls Banner, so he named it "Soul Gold".

Su Baichen looked at his Wuxiang Banner and felt that there was indeed an opportunity to upgrade it.

Although his Wuxiang Banner was forged using the best materials from Yuxiangke, it was still only the best materials that Yinlong Manor could find.

Judging from its characteristics, this "soul metal" is clearly much more efficient than ordinary spiritual materials, and it may indeed come in handy.

This time, Su Baichen finally saw something that could be of use to him.

He continued reading and saw Grandmaster Kunyu's method for refining this "Soul Gold" —

Good heavens, they actually extracted it directly from the soil of that cave using Xuan Yin spiritual energy bit by bit.

Because the injection of Xuan Yin spiritual energy will cause a slight change in the weight of the "Soul Gold" particles, which will then allow them to separate from the other soil impurities—the only problem is that this screening method is too slow.

According to Grandmaster Kunyu's records, it took him a month to refine a fist-sized piece of soul gold.

This Soul Gold has another special feature: it can only be melted using Illusionary Fire.

Upon seeing this, Su Baichen couldn't help but sigh. This material was clearly very suitable for the Yin Sect, so why hadn't it been passed down?

Then he realized that his grandmaster Kunyu was usually a loner and rarely saw anyone.

Apart from the mention of "Guardians" a few times in the journal, nothing else of any living being appeared in these texts.

Perhaps because of this, with the sacrifice of Grandmaster Kunyu and the Yin Sect's lack of attention to artifact crafting, his discovery became a lost secret.

Su Baichen continued reading the journal, only to find that much of the content consisted of various experiments on the "Soul Gold".

Finally, Grandmaster Kunyu determined that the most suitable application for this "Soul Gold" was indeed as the core of the puppet technique.

What is the art of puppetry?

It's actually just a mechanical puppet.

Therefore, the following content in the manuscript began to be the practice and exploration of various puppetry techniques.

Upon seeing this, Su Baichen felt that this grandmaster uncle had gone astray. He clearly had many ideas about weapon crafting, so why did he turn to puppetry and start from scratch?

However, an unexpected result appeared in the journal.

When the first puppet with Soul Metal as its core was made, it surprisingly possessed intelligence like a child!

Su Baichen was utterly stunned. He quickly flipped through the pages, meticulously searching the notes for the reason behind the puppet's emergence of sentience—

As the night passed, he slowly came to his senses.

This puppet was actually created because of the will of Grandmaster Kunyu.

This solitary grandmaster had a habit of talking to himself.

When he was researching Soul Metal and Puppet Techniques, he poured all his feelings and thoughts into this work.

And this puppet was born because of his expectations.

Just then, a ray of sunlight shone on Su Baichen's face, and he realized in a daze that he had been studying all night.

The worst part is that if sunlight can get into this godforsaken place, it must be noon!

Su Baichen felt a sense of foreboding. He hadn't taken care of the child this morning; was he in trouble?

He quickly created a clone to go over—

Suddenly he stopped, leaving the illusory clone behind, while he himself, along with the little fox Su Xiangxiang, dashed off into the cave deep within Yinfeng Gorge.

Since it's too late anyway, I might as well make myself look busy; maybe that will save me a scolding.

A moment later, he arrived at the cave where he had undergone the trial of the Soul-Suppressing Sword.

To be honest, this place is also his territory.

He reached out and grabbed a handful of soil, curiously following the instructions in Kunyu's notes to try refining soul gold.

The next moment, he could clearly feel that there were indeed some tiny particles in the soil in his palm that were slightly different after the infusion of Xuan Yin spiritual energy.

Presumably, Grandmaster Kunyu followed these differences and gradually sifted out these particles from the soil.

This is something that only those who are content with solitude can do.

Then Su Baichen put down the handful of soil in his hand, but suddenly pulled out the Luan Ke.

He suddenly swung his sword at the ground in front of him—

The next moment, a sword aura of Netherworld Earth was unleashed.

As the sword energy swept across the ground, it not only carved a trench in the ground but also stirred up many shimmering particles that floated in the air.

Soul gold!

Su Baichen had only wanted to try it out, but he hadn't expected that the Nine Netherworld Earth Sword he possessed would be so suitable for collecting soul metal.

The Netherworld Sword Qi is formed from the dual spiritual energy of Yin and Earth. When the sword is thrust out, the turned soil is manipulated to sink and press down, while the Soul Gold particles become as light as feathers under the blessing of the Profound Yin spiritual energy.

At this moment, Su Baichen could only regret that his grandmaster Kunyu was too aloof back then. If he had shared these discoveries earlier, given the abundance of talented people in the Yin Sect at that time, with everyone working together, someone would surely have discovered a way to quickly collect soul gold long ago.

At that moment, he shuddered violently—

That was the illusionary clone he left in his room that dissipated.

In other words, his master came looking for him!

However, looking at the handful of soul gold in his hand, Su Baichen felt he could be late today with a clear conscience—
