Xiao Ming's Blacksmith Shop.
Su Ming looked at the batch of Mysterious Iron the man had left behind, slightly surprised.
"If all this Mysterious Iron has to be fused in as well, it'll take quite a bit more effort."
After giving it some thought, he began proportioning the metals.
A qualified blacksmith had to be able to properly balance the ratios of different metals in order to forge the most suitable alloy.
He turned the furnace up to maximum output. Blazing flames roared, and the terrifying heat scorched his skin, casting his body in a red glow.
He tossed the Mysterious Iron onto the forge. In only a short while, it turned red-hot, and the black impurities within became clearly visible.
Su Ming possessed his Main Body Martial Soul. His First Soul Ring shone as his body began to enlarge, transforming into a vajra body.
He swung his hammer, striking the Mysterious Iron again and again.
Then, he took out a piece of Iron Essence and fusion-forged it together with the Mysterious Iron.
Throughout the process, even his Vajra Body was dyed red, as though it too were being seared by raging flames and repeatedly cleansed by the Soul Power within.
The pain from his body fed back into his Martial Soul. Likewise, the recovery effect produced when the Martial Soul was tempered by Soul Power was transferred back to his main body.
The strengthened main body would then increase the Martial Soul's strength, beginning another new cycle.
Through this repeated process, the Body Martial Soul possessed the possibility of limitless growth, so long as one did not consider the limits of the main body.
"Vajra Body!"
Under normal circumstances, the main body had limits, especially since Su Ming's body had not yet fully developed.
He did not dare excessively transfer the Vajra Body's state back onto his true main body, fearing it would affect his development.
Only during lower-intensity forging would he cancel the Vajra Body and temper himself in the Martial Soul's most normal state. During high-intensity forging, he would only take the first half of the cycle, tempering the Vajra Body alone as a way of developing this Soul Skill.
He would first raise the strength of his Vajra Body.
Once his main body had fully matured, he would absorb the Vajra Body and gradually merge it into his main body, turning it into his body's normal strength.
During the Dou San era.
"That's it!"
Su Ming borrowed power from the past, drawing upon the strength of his Body Martial Soul from twenty thousand years ago.
He did not transform into his Vajra Body. Instead, in his current state, he practiced the latter half of the process that Su Ming of the past had not carried out.
As he felt his main body being continuously tempered, every cell in his body greedily absorbed the energy accumulated within him. Even his soul seemed to be purified, as though it were immersed in a cradle and enjoying the nourishment provided by his body.
The soul was the essential characteristic of a living being.
It did not matter if the body was gone. As long as the soul remained, one could still possess another body.
But the soul was ultimately rooted in the body and relied on it to nurture the mind.
Now, every cell in Su Ming's body had entered an extremely comfortable state, nourishing his soul and allowing it to grow vigorously. Converted into Spiritual Power, that meant he had gained a full five points of Spiritual Power today!
"Five points a day—wouldn't that be fifteen hundred in a year?" Su Ming remarked.
Of course, he was joking.
First, the body had its limits and could not be trained excessively too early. He did not want to become a hulking giant like A'Ruheng. Second was the cost. His body tempering and Spiritual Power growth were both bought with Contribution Points. Every day, he consumed high-grade ingredients and accumulated a great deal of energy within his body, while today he had also undergone a Heavenly Materials and Earthly Treasures-grade dietary supplement.
This kind of improvement was destined not to happen every day.
Once a month was already the limit.
Even so, that would amount to sixty points of Spiritual Power in a year. Combined with the Spiritual Power gained through daily tempering, his annual improvement would still reach triple digits—simply terrifying.
The rate at which Spiritual Power increased accelerated alongside one's realm. At his current stage, having just awakened his Martial Soul, gaining triple-digit Spiritual Power in a year was downright monstrous.
Moreover, it was not just his Spiritual Power that was improving. His physical fitness far surpassed that of his peers, and his Soul Power growth had not fallen behind either. He crushed others across the board.
"Still not outrageous enough. After all, I've only benefited from the Body Martial Soul. Even A'Ruheng, who cultivated the Body Martial Soul to its peak, couldn't compare to Tang Wulin's Golden Dragon King Bloodline."
If you're bad, train more.
So—
"I need to train more."
If this had been right after awakening his Martial Soul, Su Ming would not have possessed such motivation or conviction. But after his First Soul Skill could draw upon the power of his two past selves, he finally had confidence.
The boost brought by the Trinity Martial Soul Fusion Skill was simply too great.
The Body Martial Soul could feed the Martial Soul's power back into the main body, so why could the Martial Soul Fusion Skill not do the same?
"What I'm borrowing isn't the power of some random person from the Time River. It's my own power, perfectly compatible with me. In other words, my Trinity Martial Soul Fusion Skill is a Self Martial Soul Fusion Skill."
"By fusing the Body Martial Soul and Soul Power Martial Soul, I can absorb all the improvements gained while in the Trinity Martial Soul Fusion Skill state into my own body. That will then drive the Trinity Martial Soul Fusion Skill to improve further, and I can turn that into my own strength as well, repeating the cycle."
This path of continuously growing stronger through positive feedback absorbed Su Ming completely.
He turned off the device used to test Spiritual Power.
The number 200 on the screen displaying his Spiritual Power gradually disappeared.
As the era advanced, cultivation in the Soul Master World became increasingly comprehensive. From the primitive era of Dou Yi, when everything depended on Martial Soul aptitude and Soul Masters blindly explored in the dark, they later began researching how to absorb Soul Rings beyond their level and gradually started exploring the physical realm. Among them, naturally gifted Martial Souls like the Body Martial Soul stood out, and the Body Sect, formed from Body Martial Souls, enjoyed immense prestige for a time.
Later, after the Ice Spirit Douluo created the Spirit System and built the Spirit Pagoda, Soul Masters entered the era of Soul Spirits. In order to fuse with more Soul Spirits of higher age, they began exploring the realm of Spiritual Power.
Everything went exceptionally smoothly.
Because Soul Spirits were simply too perfect.
A Soul Spirit gave every Soul Master aptitude in the Mental Attribute!
Even for Martial Souls without a Mental Attribute, the process of fusing with a Soul Spirit stimulated a Soul Master's Spiritual Domain. Soul Spirits that could reside within the Sea of Consciousness were naturally the best tools for Soul Masters to develop their Spiritual Domains.
This was Su Ming's summary of Douluo Continent's development over the past twenty thousand years.
Soul Spirits were the key to exploring the Spiritual Domain!
"Over the past year or so, my Soul Power and physical fitness have improved significantly, but my Spiritual Power growth has lagged behind."
A seven-year-old Soul Master with two hundred points of Spiritual Power would have been hailed as a monster even at Shrek, yet Su Ming called it lagging behind.
"Spiritual Power at the Spirit Connection Realm can support a purple Soul Spirit. I should have entered the Spirit Ascension Platform long ago, but exchanging for it with Contribution Points was too expensive, so I waited until now."
Su Ming sighed helplessly.
He remembered his teacher, Zhang Tianyang, saying it would take half a year at the shortest and a year at the longest, yet his closed-door cultivation had exceeded that by two full months.
Fortunately, his cultivation schedule had always been packed, so this period had not been wasted.
"Teacher, your disciple has come to see you with a surprise."
