["Hiss, it can't be..."]
[The sound of Yu Xiaogang sucking in a cold breath naturally caught the attention of Yu Yuanzhen and the Grand Elder.]
[They immediately understood that Yu Xiaogang had thought of something.]
["Xiaogang, quickly, tell us, what did you think of?"]
[Yu Yuanzhen asked impatiently.]
[He noticed that ever since his son began to Cultivate, he often took on this curious, baby-like posture.]
[But he couldn't blame him for being curious; his son's Martial Soul had so many quirks. Yu Yuanzhen, who considered himself very knowledgeable about the Martial Soul system, had become a mere witness to new tricks in front of his son.]
[If he didn't figure these things out properly, wouldn't it be too embarrassing if he couldn't say anything the next time a similar situation occurred?]
["Whew, wait a moment, I need to think it through in my head first."]
[Yu Xiaogang did not answer immediately, but instead fell into a state of deep thought.]
[Because just now, Yu Xiaogang suddenly discovered that the Martial Soul Possession state he completed with Little Dragon actually fit perfectly with another system of the Douluo Continent:]
[Martial Soul Fusion Skill!]
[Martial Soul Fusion Skill, a special combat skill that countless Spirit Masters dream of possessing.]
[To activate a Martial Soul Fusion Skill, two or more Spirit Masters need to launch it together through Martial Soul resonance.]
[Once a Martial Soul Fusion Skill is activated, its power far exceeds the sum of the individual abilities of the Spirit Masters before the Fusion.]
[It is an effect where one plus one is far greater than two.]
[To activate a Martial Soul Fusion Skill, there are almost harsh requirements for both Spirit Masters' Martial Soul compatibility, spirit power resonance, mental synchronization, and many other aspects.]
[For instance, the two Spirit Masters must share the same mind, have deeply compatible Souls, and possess absolute trust in each other.]
[The Martial Souls must also possess the conditions for Fusion, being able to complement each other in attributes, forms, abilities, and more.]
[In short, possessing a Martial Soul Fusion Skill is even more difficult than obtaining a Spirit Bone.]
[In the current Douluo Continent, the Dai and Zhu families of the Star Luo Empire's imperial family can consistently produce Spirit Masters who can use the Martial Soul Fusion Skill—Hell White Tiger.]
[This is also the foundation of the Star Luo Empire's Dai and Zhu imperial families.]
[As long as these two families can still produce Spirit Masters capable of using the Hell White Tiger, their Alliance is unbreakable.]
[Besides them, the two Spirit Douluo, Yue Guan and Gui Mei, can also perform a Martial Soul Fusion Skill.]
[Then there is a famous Spirit Master couple, Meng Shu and Chao Tianxiang. Because they are husband and wife, possess significant strength, and have a Martial Soul Fusion Skill, people call them the 'Unrivaled Dragon and Serpent'.]
[These are all the Martial Soul Fusion Skills in the current Douluo Continent.]
[Only three types. From this, one can see the rarity of Martial Soul Fusion Skills.]
[However, the Martial Soul Fusion Skill lives up to its rarity.]
[As long as two Spirit Masters can perform a Martial Soul Fusion Skill, they will be teammates who share life and death.]
[Absolute trust is one of the conditions for performing a Martial Soul Fusion Skill.]
[No Spirit Master would choose to betray the person they can perform a Martial Soul Fusion Skill with.]
[By comparing his own Martial Soul Possession with the Martial Soul Fusion Skill, Yu Xiaogang was shocked to find that his Martial Soul Possession was practically no different from a Martial Soul Fusion Skill.]
[A Martial Soul Fusion Skill requires two or more Spirit Masters to activate.]
[And he and Little Dragon happened to be two separate entities.]
[A Martial Soul Fusion Skill requires both Spirit Masters to share the same mind, have deeply compatible Souls, and possess absolute trust.]
[And he and Little Dragon indeed shared the same mind, had deeply compatible Souls, and possessed absolute trust.]
[These conditions were easy for him and Little Dragon to fulfill; after all, Little Dragon was his Martial Soul and was already a part of him.]
[In this World, who could not trust themselves? Or whose Soul could not be deeply compatible with their own?]
[No one!]
[So he could perfectly fulfill this condition.]
[Then there is the requirement for both parties to complement each other in attributes, forms, abilities, and more.]
[Although this part was a bit forced, it still made sense.]
[As a Spirit Master, without Little Dragon, he had no Martial Soul, no attributes, and no abilities.]
[As a Martial Soul, without him, Little Dragon had no body to carry it, no spirit power supply, and no consciousness of its own.]
[Little Dragon's arrival supplemented his deficiencies in all areas, and he also made up for Little Dragon's deficiencies. How could that not be considered a form of complementarity?]
[Before Little Dragon could undergo its second Awakening and gain the ability for Martial Soul Possession, he and Little Dragon could only fight side by side, just like two Spirit Masters.]
[Now that Little Dragon had completed its second Awakening and gained the ability for Martial Soul Possession, and he and Little Dragon had successfully merged into one, by analogy to Spirit Masters, wasn't this equivalent to performing a Martial Soul Fusion Skill?]
["If that's the case, it would explain why my Martial Soul Possession is so unique."]
[Yu Xiaogang muttered to himself.]
[After a Martial Soul Fusion Skill is performed, it creates an effect where one plus one is far greater than two.]
[And when he completes Martial Soul Possession, that massive boost from an unknown source fits perfectly with that 'one plus one is far greater than two' effect.]
[As for why the spirit power increase was greater than the physical enhancement?]
["In that case..."]
[Yu Xiaogang looked at Little Dragon, who was resting in his arms.]
["Little Dragon, let's try it again!"]
[Hearing Yu Xiaogang's words, Little Dragon nodded without hesitation.]
[To the side, Yu Yuanzhen and the Grand Elder exchanged a look. Although neither knew what Yu Xiaogang had thought of, they both tacitly refrained from interrupting.]
[Under their watchful eyes, with a flash of light, Little Dragon once again transformed into its complete form.]
[Looking at Little Dragon's body, Yu Xiaogang took a deep breath, walked to Little Dragon's side, and reached out to touch its body.]
[In the next second, just like Little Dragon had done during the first Martial Soul Possession, Yu Xiaogang turned into light and injected himself into Little Dragon's body.]
[Instantly, Little Dragon's massive body began to emit light.]
[When the light dissipated, Yu Xiaogang opened his eyes and found that his field of vision had become much higher.]
[He looked down and, as expected, saw the figures of his father and the Grand Elder.]
[Controlling the body to lift an arm, Little Dragon's dragon claw came into view.]
[Then, feeling his current body, an unprecedented sense of power flooded through him.]
[Yu Xiaogang even felt that with his current physical strength, he might be able to fight a Ten-Thousand-Year Soul Beast in the Star Dou Great Forest relying solely on melee combat.]
["It really is like this!"]
[Yu Xiaogang—or rather, Yu Xiaogang, who had completed Martial Soul Possession and become an Incarnation of a giant dragon—had a sharp glint in his eyes.]
[He had completely understood exactly what was going on with his Martial Soul Possession.]
