Reading guide: In "Immortal Rebellion", strength is respected, and every choice of the strong may affect the direction of the battle and even change their own fate. Sun Tai, as the Great Elder of the Corpse Yin Sect, has a powerful cultivation in the middle stage of the Infant Transformation, and in the battle with the Troll Ancestor and Li Yuanfeng, he did not summon the Demon Boy at the first time, which is puzzling and has also caused a lot of speculation.

From Sun Tai's standpoint, he did not voluntarily become Wang Lin's slave, but was defeated by Zhou Yi after breaking through to the peak period at the cost of burning his soul, and used his mental imprint to control him, and was forced to be driven by Wang Lin for a thousand years. When Wang Lin was chased and killed by Li Yuanfeng and the Troll Ancestor, when he was summoned to come to the rescue, his heart was actually full of resistance. He didn't want to get involved in this fight, but because he was bound to Wang Lin's life, if Wang Lin died, his life would not be guaranteed, so he had to take action. Therefore, he subconsciously didn't want to expose all his hole cards too early, and the magic boy, as his strongest combat power, was naturally kept by him as a backhand.

From the analysis of the battle situation, Sun Tai faced the opponents at the beginning of the Infant Transformation Stage, the Troll Ancestor, and Li Yuanfeng, who was forcibly promoted to the Infant Transformation Stage by relying on the secret method of the Vermilion Bird Kingdom. With his mid-infant strength, he had a certain advantage from the beginning, and he was confident that he could deal with it, thinking that there was no need to summon the demon boy immediately. He may want to suppress the opponent with his own strength first, and quickly lead Wang Lin out of danger, there is no need to use the strongest means. After all, although the demon boy is strong, summoning and manipulating it will inevitably consume a lot of spiritual power and energy, and he still needs to be distracted to protect Wang Lin during the battle, summoning the demon boy too early, once the battle falls into a protracted battle, the follow-up may fall into trouble due to lack of spiritual power.

There are also some factors in the Demon Boy itself that affect Sun Tai's decision-making. The Demon Boy was made by Sun Tai who spent three hundred years of time refining the corpses of eight hundred Avatar Cultivators, fusing the unique techniques of the Corpse Yin Sect and the unique meteorite iron of the Luo Tian Star Domain, and possessed the powerful strength of the middle stage of the infant transformation. But it is too powerful, and once summoned, the nature of the battle will change, and it is very likely that the opponent will be killed. Sun Tai may not want to make the situation out of control, after all, he has no deep hatred with the Troll Ancestor and Li Yuanfeng, there is no need to kill them all, his purpose is just to take Wang Lin away. And once the magic boy is exposed, it may trigger the opponent's targeted counter strategy, and Sun Tai chooses to act cautiously when he is not clear about the opponent's hole cards.

However, Sun Tai underestimated the Troll Ancestor's obsession with the Heavenly Reverse Pearl. In order to get the Heavenly Reverse Pearls on Wang Lin's body, the Troll Ancestor did whatever it takes, even in the face of Sun Tai, whose strength is higher than his own, he resolutely refuses to stop. During the battle, the Troll Ancestor showed a special physique and natural powers, which made Sun Tai fearful. In particular, his natural supernatural powers, although they are not directly lethal, they can teleport opponents to distant unknown star fields, and this unpredictable spatial law secret technique makes Sun Tai full of defense. But even so, Sun Tai did not summon the Demon Boy at first, and it was not until he was teleported by the Troll Ancestor's talent that he summoned the Demon Child at the last moment and ordered him to kill the Troll Ancestor.

So, if Sun Tai summons the Demon Boy for the first time, what will be the result? Judging from the comparison of strength, the Demon Boy and Sun Tai are both in the middle stage of the infant transformation, and the two will join forces to quickly suppress the Troll Ancestor and Li Yuanfeng. Li Yuanfeng was already powerless in front of Sun Tai, and with the demon boy, he had no room to resist; Although the Troll Ancestor has natural supernatural powers, in the face of the attacks of the two mid-stage infantile powerhouses, it is likely that he will not even have a chance to use his supernatural powers, and he will be defeated. In this way, Sun Tai will not only be able to easily save Wang Lin, but he will not be teleported to the distant Donglin Star and become a subordinate for a hundred years of enslavement, causing the Dao Heart to be shattered and his cultivation to decline.

But thinking about it from another angle, even if Sun Tai summons the magic boy to win at the first time, it may cause other problems. For example, an excessively powerful display of power may attract more forces that covet the Heavenly Reverse Pearl, bringing follow-up trouble to Wang Lin and himself; It may also cause the fear of other powerhouses in the cultivation realm, and make a big move, laying hidden dangers for the future cultivation path.
