The next morning, Xiao Lin and Tang San met at the entrance of Shenghun Village, chatting about the contents of the Soul Saint's book.
"Lin Ge (Brother Lin), I've thought it over. That spirit grass might be right beneath that mutated Evil Eye Demon Tree, underground," Tang San said unclearly as he munched on the steamed bun Old Jack had prepared for him.
"I had guessed that already. That mutated Evil Eye Demon Tree should be the manifestation of the Soul Saint's martial soul," Xiao Lin replied.
"But can a human's martial soul really turn into a plant, or a spirit beast?" Tang San asked, confused.
Xiao Lin also wasn't quite sure.
Generally speaking, martial souls have three forms:
Completely intangible spirit images.
Summoned forms made of soul power.
Physical martial souls.
The completely intangible kind is represented by auxiliary martial souls like the Seven Treasure Glazed Pagoda. This kind of martial soul has no attack capability because it has no physical form—it's just a phantom.
Xiao Lin wondered if it was because the Seven Treasure Glazed Pagoda's auxiliary powers consumed too much soul power, or because it was too fragile and could be damaged by enemies, resulting in backlash. So it only summons a spirit image to assist directly.
Otherwise, no matter what, the Seven Treasure Glazed Pagoda could be used to strike enemies physically.
Second is the summoned form made of soul power, which makes up the majority of martial souls.
Xiao Lin's Qiu Dragon Staff, Tang San's Blue Silver Grass, Tao Ge's Lone Wolf, and Yu Xiaogang's Luo San Cannon are all soul power-constructed martial souls.
These martial souls do not physically exist as material objects.
If these martial souls are damaged, the soul master also takes damage, and serious injuries can incapacitate or even kill the soul master.
The last type is a kind of fusion martial soul.
For example, when one's martial soul fuses with a physical soul instrument in reality to form a new martial soul.
This kind of martial soul only exists in Xiao Lin's theory because he knew of someone during the Absolute Lord Tang Sect period whose martial soul was damaged and fused with a physical material, becoming stronger.
Xiao Lin still didn't know if that martial soul counted as soul power-based, physical, or somewhere in between.
But the mutated Evil Eye Demon Tree in the cave matched all the Soul Saint's martial soul abilities, and Xiao Lin couldn't find any other explanation.
Eliminating all impossibilities, whatever remains, no matter how improbable, must be the truth.
Xiao Lin's mind flashed with this thought: either the mutated Evil Eye Demon Tree is the manifestation of the Soul Saint's martial soul,
or the Soul Saint found the seed of the Evil Eye Demon Tree and cultivated it by similar methods.
The spiritual simulation head soul bone, that seed turned into spirit grass, absorbed by the Evil Eye Demon Tree.
Hearing Xiao Lin's question, Tang San scratched his head and said uncertainly, "Lin Ge, I read that Soul Saint's book, and I seem to have some impression of that yellow spirit grass."
"You?" Xiao Lin asked in surprise.
Tang San nodded slightly with certainty. "Aren't I researching the flowers and herbs that look the same in both worlds?"
Xiao Lin knew about Tang San's research into whether herbs that look identical in two worlds have different medicinal effects, so he nodded and asked, "And then?"
"Then, that yellow spirit grass seemed familiar."
Thinking for a moment, Tang San described what the book said and some legends he had heard in his previous life.
"The book says it's a very beautiful yellow spirit grass. Each leaf looks like it's made of transparent crystal. The stems and leaves contain mysterious energy and emit a faint yellow glow."
"And there's more. Legend says this spirit grass can regenerate under special circumstances, performing soul transfer, and only grows in places with sufficient vitality."
As he spoke, Tang San even exaggerated a bit, telling stories from past legends.
"It's said to be very rare, symbolizing purity, eternity, and rebirth, and it can record the voice of the soul."
"Also, this spirit grass is extremely rare, and no one can cultivate it."
Tang San got excited and waved his hands as if urging Xiao Lin to imagine the grass out of thin air.
"That's impossible, Xiao San. How could it really regenerate?" Xiao Lin was about to refute, but the special ability linked with the mutated Evil Eye Demon Tree made him shut his mouth.
"So, what is this grass?"
"Dusk Grass, also called Yellow Soul Grass."
Tang San spoke the name from his past life weakly, relying only on the description. He didn't even know if this world actually had such spirit grass.
"Strange name," Xiao Lin said sarcastically, pondering the possibilities.
First, the mutated Evil Eye Demon Tree fits the description, and Yellow Soul Grass grows in places with vigorous vitality.
Isn't the Star Dou Great Forest core area near the Life Lake?
Plus, among the Evil Eye Demon Tree clan, there's a fierce beast called the Ten Thousand Demon King, so the chance of getting Yellow Soul Grass is not small.
Soul voice—that's the sonic control, right?
But there's one more doubt.
What level of grass is this Yellow Soul Grass?
Spirit grass or fairy grass?
Tang San said spirit grass, so it probably couldn't have regeneration ability.
Because even fairy grass can't do that.
Rather than saying the mutated Evil Eye Demon Tree is the Soul Saint's rebirth, it's more likely the martial soul mutated and gained life.
More like the seed left by the Blue Silver Emperor A Yin after her sacrifice.
Soul and vitality transformed into soul rings and soul bones, left with Tang Hao; that seed was the newborn Blue Silver Emperor seed.
Later, when Tang San resurrected his mother, he triggered that seed, forcing A Yin's revival by a kind of soul takeover.
Regardless, Xiao Lin had no doubts about Tang San's words.
If a fairy grass unknown even to the natives of Douluo Continent appeared, Tang San knowing about it was very likely.
"Then it's settled. Next holiday, let's go look for that Yellow Soul Grass seed."
"This thing might even bring your mother back, Xiao San."
Xiao Lin smiled faintly and extended his fist.
Tang San was stunned for a moment but then broke into a bright smile and bumped fists with Xiao Lin.
The two made a silent pact.
Xiao Lin smiled and suddenly remembered that the Tang San from the original timeline had consumed a lot of the Sea God's light and power to revive A Yin and Xiao Wu.
But the Tang San in this world specializes in vitality, so maybe he won't need the Sea God's light.
If so, he'd be able to milk the Sea God's power hard and get an ultra-strong ultimate soul ring.
"Qiu Dragon Staff, you've got to absorb a lot more."
Speaking of Tang San specializing in vitality, maybe he could inherit the Life God's position.
Then the Sea God's power could be absorbed by Tang San and Xiao Wu too.
Also, maybe the Sea God's power could help him form a second martial soul.
Xiao Lin, already thinking of the Sea God as a huge source of resources, chuckled out loud in front of Tang San.
"Lin Ge, why are you laughing?" Tang San was a bit puzzled.
"Nothing, just thinking about something happy."
"I'll tell you, after I broke through to level 20, my Great Strength Bull Demon Horn evolved."
Saying this, Xiao Lin demonstrated it in front of Tang San.
Two large horns slowly grew on both sides of Xiao Lin's forehead, with several golden spirals, each about the length of an index finger.
"Strength doubled and a half, and when I reach level 30, it'll strengthen to triple."
"Also, soul power storage increased by 20%. Every 10 levels after that, another 20% increase. Maybe soon, I'll be able to release soul power lasers."
Seeing a hint of envy in Tang San's eyes, Xiao Lin proudly continued: "This is the growth potential of an external soul bone."
"In the future, I'll make sure to find you an external soul bone, Lin Ge."
He patted Tang San's shoulder and laughed heartily.
"Thanks, Lin Ge," Tang San said gratefully, his face touched.
He trusted Xiao Lin's research on external soul bones and soul bones.
