As his spiritual world expanded, Lu Chenxing's spiritual power also rapidly increased. At the same time, the rule seeds that had grown to a certain extent began to grow again.
Under the pouring of a large amount of energy, in just a few moments, these seeds had grown by more than double, and the seeds of light, fire, and spiritual power were still growing!
A moment later, to Lu Chenxing's surprise, the seeds of these three appeared in his spiritual world in their physical forms. Three teardrop-shaped seeds, red, gold, and transparent, floated around the projection of his spiritual body.
Moments later, cracks crawled up them, and with a "crack" sound, three new rules appeared in his mind!
"Original Light," "Original Fire," and "Source of Spirit"—one shaped like a small sun, one like a small flame, and one a transparent sphere.
When these three appeared, a large amount of energy surged towards them, causing them to grow rapidly. When they grew to the same size as the "Yin-Yang Way," they stopped growing and then disappeared into the spiritual world.
At this moment, Lu Chenxing was completely stunned. He had never heard of these three rules before, but judging by the density of their rule power, they were probably on par with the "Yin-Yang Way"!
One must know that the "Yin-Yang Way" was a top-tier rule! Did this mean he now had three rules not inferior to the Yin-Yang Way?
Before he could examine them closely, a large amount of energy, under the effect of the "Source of Spirit" rule, rapidly transformed his spiritual power. Both quality and quantity were improved simultaneously, and his spiritual world, which had gradually stopped expanding, began to expand again!
Rumbling sounds were incessant!
When all of Lu Chenxing's energy was exhausted, his spiritual world had expanded dozens of times, and the quality and quantity of his spiritual power were also dozens of times stronger than that of a third-tier early-stage expert of the same rank!
At this time, the energy brought by the Yin-Yang Fish was exhausted, and the immortal stone on the top of Huaguo Mountain returned to silence. Huaguo Mountain, surrounded by a large area of barren land, even appeared somewhat abrupt.
Lu Chenxing, who was in a state of shock from the series of drastic changes, now had time to examine the three new rules he had obtained, starting with the "Source of Spirit"!
When he began to carefully comprehend this rule, he realized why his spiritual world had undergone such a drastic change again!
Besides containing characteristics like Hope, unyieldingness, and stability, the "Source of Spirit" also had a final passive effect: "greatly increased spiritual power quality, total amount, and recovery speed." It was this point, combined with that immense energy, that allowed Lu Chenxing's spiritual world to undergo a second expansion!
He then looked at the effects of the "Original Light." It had removed spiritual aspects like Hope, which had all been moved into the Source of Spirit.
Now, its effects, in addition to all conceivable light-based rule characteristics such as perpetual brightness, radiance, and dawn, also included the characteristic of "being able to dispel all darkness."
And the effect of the last one, "Original Fire," was similar. Besides all the rule characteristics he had heard of, such as high temperature, explosive combustion, and imperishability, it also gained the characteristic of "being able to burn everything."
This made Lu Chenxing's eyes widen. What was this? Were there such overpowered things in this world?! And what did that last additional characteristic mean? Was it conceptual?
And why did only these three rule seeds mature first? Was it because these three systems previously had a complete rule?
Various conjectures flashed through his mind. After a long while, Lu Chenxing finally calmed down, feeling the increased total amount and quality of his spiritual power. For a moment, he couldn't help but feel some happy troubles!
Because although he became stronger, it also meant that when he next advanced, he would need to increase his spiritual power even more!
For him, who already found advancement difficult, the difficulty would probably increase again! Sometimes, an overly strong foundation, if not supported by corresponding resources, could be either a good thing or a bad thing.
Although he felt that his current spiritual power seemed not far from breaking through to the mid-third tier, the difference between them could very well be the total spiritual power of several normal third-tier professionals.
And when Lu Chenxing shifted his attention from his spiritual world back to his physical body, his mouth couldn't help but widen again!
The pool of clear liquid from before had now completely disappeared, and his body, in terms of physical quality, meridian flexibility and width, total magical power and quality, and various other aspects, had also improved by dozens of times!
It was almost a synchronized improvement with his spiritual power, and he felt that his current total magical power was also not far from breaking through to the mid-third tier!
But like his spiritual power, the gap between the two could very well be the sum of the magical power of several mages of the same rank!
"This senior was indeed thoughtful," Lu Chenxing couldn't help but smile, because even a mage couldn't truly only focus on spiritual power. If the physical body couldn't bear overly strong spiritual power, the final result could only be the collapse of the physical body.
But now, Lu Chenxing's physical body, after being transformed by the pool water, was only slightly inferior to his spiritual power. He would no longer have such concerns in the future!
Lu Chenxing stood up, bowed towards the former location of the Corpse Refining Demon Lord, and then bowed towards the sky, showing his gratitude to these two seniors. After all, having received kindness from predecessors, one must be grateful.
After bowing, Lu Chenxing stood straight. Yin Power surged through his body. In an instant, his aura and magical power were completely hidden, not leaking a single bit!
Although he stood there, if someone were to scan with spiritual power or investigate with Wind Element, they would find no one there!
Of course, these were all based on situations where the strengths were not too different. According to the current situation, at least below the sixth tier, no one would be able to detect the rule power on Lu Chenxing. Even a sixth-tier expert would need to investigate carefully!
"In that case, my life-saving trump cards have increased!" Lu Chenxing said with a smile. Then, a wisp of flame ignited on his fingertip, imbued with the rule characteristic of "Original Fire," and he threw it onto a nearby stone.
Normally, this flame would extinguish upon touching the stone, but not now. It treated the stone as fuel and began to burn directly!
Watching the flame slowly devour the stone bit by bit, Lu Chenxing couldn't help but think, what would it be like if this "burn everything" characteristic was combined with "imperishable" and "spreading like wildfire" characteristics!
If this move were used on someone, it probably wouldn't stop until they were burned to charcoal! Unless there was a stronger rule power to erase the rule characteristics in the flame, or Lu Chenxing actively withdrew it, if one was hit by it, there truly was only death!
