Heroic Spirit Awakening: Is It Reasonable for Me to Summon the Dragon?

[Revival of spiritual energy + stocking up + decisive killing + no heroine + kill the Virgin first + awakening of heroic spirits] The void explodes, rain of blood falls, heaven and earth undergo sudden changes, all things revive, and spiritual wisdom opens. In just one day, the entire earth changed dramatically. But soon everyone discovered that they could awaken heroic spirits. There is someone named Qin who has the blood of the Qin family and awakened Qin Shihuang, Qin Qiong, etc. There is someone named Zhao who has the blood of the Zhao family and has awakened Zhao Kuangyin, Zhao Guangyi and so on. Someone named Xiang, with the blood of the Xiang family, awakened Xiang Yu, Xiang Yan, etc. Every heroic spirit is divided into levels. The strongest heroic spirit is SSS level, and the weakest heroic spirit is only F level. In the previous life, Jiang Yanbing summoned Jiang Wei, but in this apocalyptic world where all the heroes are together, he can only be regarded as average, only B-level. Because of his own weakness, he was betrayed by his girlfriend, stabbed and abandoned by the organization, and died in a long-planned plan. After returning from time travel, Jiang Yanbing decided not to trust anyone but the strong. There are also some mythical characters that can be summoned, such as Pangu, Taoist Hongjun, Demonic Ancestor Luohu, Nuwa, etc. In the previous life, a lucky person stained the Pangu statue with blood and obtained the Pangu Heroic Spirit. If you want to summon various gods, you only need to shed your own blood on the statue of the god, and there is a chance of summoning the heroic spirit of the god. When Jiang Yanbing knew this secret, almost all the gods were overtaken. His return from time travel means he has the opportunity to be one step ahead. Jiang Yanbing chose a temple in a barren mountain near his home. The temple enshrined one of the most powerful gods... And then he could summon the dragon.
