The clash of two formidable powers instantly made this ability terrifying beyond anything seen before.
Tang San's own explanation of this skill later on was simple: to see through all things in the world and obliterate every form of injustice. The skill was called Purple Divine Light.
A beam of Purple Divine Light shot out. The first thing Tang San felt wasn't excitement — it was an immediate, rapid calculation of exactly how much destructive force that beam had produced. This was something he would never have paid attention to before, but now his brain performed the computations automatically, everything flowing naturally and effortlessly.
The moment the thought of calculation crossed his mind, Tang San began estimating based on the shattered remains of the boulder before him and the marks left on the ground. He determined that the Purple Divine Light he fired from his eyes was a concentrated, pinpoint attack. Because the offensive power was focused to a single point, its individual destructive force was absolutely devastating. Moreover, he discovered that the intensity of the Purple Divine Light was directly tied to his spiritual energy output.
When he had been gazing at the pool moments ago without triggering any attack effect, his spiritual energy had been consumed at an extremely slow rate. But the instant he shifted his gaze to the boulder and launched the attack, his spiritual energy surged out like a gushing spring. His soul power consumption, on the other hand, was minimal. In other words, this skill primarily drew on spiritual energy — the more spiritual energy he channeled into it, the stronger its offensive power became.
Once he understood this, Tang San also noticed that his spiritual energy had increased by at least a hundredfold compared to before. What had once been invisible and formless now converged into a flowing river within his mind, shimmering with a faint silver glow as it drifted along. Wherever it passed, it illuminated everything within his mental landscape, allowing Tang San to perceive far more than he ever had.
Since the power of Purple Divine Light was connected to spiritual energy, then it seemed he really ought to begin cultivating his spiritual energy seriously.
The Great Master had once taught Tang San methods for spiritual energy cultivation, but at the time Tang San had devoted most of his effort to practicing the Mysterious Heaven Skill. He had considered spiritual energy to be nothing more than an ethereal, intangible thing — hardly something of real use. But now, it suddenly clicked. The role of spiritual energy was enormous. In a certain sense, it was by no means less important than his soul power.
The more powerful a soul master was, the greater the pressure they exerted on others. Where did that pressure come from? Partly from the release of soul power, certainly, but equally from spiritual intimidation. That was the function of spiritual energy. And beyond that, his new Purple Divine Light also depended on spiritual energy to fuel it. Having a skill that barely consumed soul power yet packed such devastating offensive punch was, for Tang San, like a tiger that had sprouted wings.
Suddenly, Tang San was startled. He realized that after firing just a single beam of Purple Divine Light, he had somehow produced all of this analysis. And every thread of reasoning fit together seamlessly, as though his conclusions were simply self-evident facts. The Wisdom Skull — was this the wisdom it had granted him?
No wonder every soul master covets soul bones with such desperation, Tang San marveled inwardly. He had obtained the External Spirit Bone Eight Spiders' Lure while absorbing a soul ring. Afterward, the Eight Spiders' Lure had given him tremendous benefits as well. But even so, acquiring the Eight Spiders' Lure had not come close to the impact of obtaining this Wisdom Skull.
This Wisdom Skull had essentially opened an entirely new door in soul master cultivation for Tang San. The benefits it bestowed went far beyond just the Purple Divine Light.
Tang Hao had been standing to the side the whole time without saying a word. One could tell from Tang San's contemplative expression that his son was now absorbing everything he had just gained. This moment was critically important. Tang Hao could roughly guess what the Wisdom Skull had given Tang San, which was precisely why this period of reflection was so invaluable.
After a long while, Tang San gradually emerged from his thoughts and looked toward his father. He noticed that even without consciously using his eyes, the invisible spiritual energy emanating from his mind had already locked onto his father's position. What surprised him even more was that the spiritual energy in his mind required no deliberate control — it was slowly recovering on its own.
This spiritual force had nothing to do with the outside world; it regenerated entirely from within himself. The Great Master had once said that a person's spiritual world was the most mysterious place of all. No one truly understood where spiritual energy came from. On the surface it appeared ethereal and intangible, yet it undeniably existed. The more powerful a soul master was, the stronger their spiritual energy.
What Tang San didn't know was that Tang Hao was quietly astonished as well — astonished by the intensity of his son's spiritual energy. Tang Hao discovered that the spiritual energy Tang San currently possessed had already approached the level of an ordinary Soul Douluo. He understood that this was absolutely not something a single Spirit Condensation Wisdom Skull alone could have achieved.
That soul bone could certainly enhance Tang San's spiritual energy and allow him to glimpse the mysteries of the spiritual world. But its effect should never have been this powerful.
In truth, for Tang San, the Wisdom Skull was more like a key. And it was precisely this key that had opened the door to his spiritual world.
Ever since he was a child, Tang San had faced the rising sun every morning to cultivate the Purple Extreme Demon Eye. What he hadn't known was that this practice was not merely training his eyes — it had been tempering his spiritual energy all along. The only reason was that this cultivation had remained hidden deep within his mind, never surfacing. Now, under the influence of the Wisdom Skull, years of accumulated training suddenly connected and unlocked. The door to his spiritual world flung wide open, producing this explosive leap in growth.
Of course, what had reached the Soul Douluo level was only Tang San's spiritual tier. That did not mean his Purple Divine Light could now wield Soul Douluo-level power. Everything would depend on how his spiritual energy continued to grow in the future and how much of it he channeled when activating Purple Divine Light.
Tang San gradually came back to himself and looked at his father.
Tang Hao walked up to him. "You absorbed it for three days. Based on your condition and the time it took, this soul bone most likely belonged to a soul beast of over sixty thousand years. Your luck is quite good. I suspect that if I hadn't appeared, Spirit Hall might have made a covert move against you. This soul bone would rank among the upper tiers even within Spirit Hall."
"Three days?" Tang San was startled. "Dad, that means you haven't rested for three days."
Tang Hao waved his hand dismissively. "That's not important. Your intensive training begins now."
The moment he finished speaking, Tang Hao raised his hand and tapped Tang San once on each shoulder and once on his chest. Three streams of scorching heat plunged downward simultaneously. Tang San felt his entire body go numb with a single shudder. Almost instantly, his dantian was engulfed by a searing wave of heat. With his current level of spiritual energy, he could no longer sense even a trace of his soul power.
"Dad, what are you…"
