If the Sun Moon Empire, the Holy Spirit Cult, and the Civilization Research Institute also allied with the two great Soul Beast Lands, the Far North and the Evil Demon Forest, their top experts would be no weaker than those on Shrek's side.
The Sun Moon Empire had two top Soul Engineers, Ye Yulin and Kong Deming. Kong Deming had long since become a Level 10 Soul Engineer, and his current strength was even more unfathomable. Like Jing Hongchen, Ye Yulin now had the strength to fight a Limit Douluo and could be called a Quasi-Level 10 Soul Engineer. In war, a Level 10 Soul Engineer would only pose a greater threat than a Limit Douluo.
The Holy Spirit Cult had lain dormant for over a thousand years, and its reserves ran even deeper than the Body Sect's. Its three Limit Douluos-Long Xiaoyao, Ye Xishui, and Zhongli Wu-were all top experts. Aside from Zhongli Wu, whose foundation was comparatively shallow, Ye Xishui was both a Limit Douluo and a Level 10 Soul Engineer, while Long Xiaoyao had previously been the strongest human expert on the Douluo Continent.
Furthermore, they had powerful Soul Beast allies such as the Demon Empress and the Evil Emperor.
The Civilization Research Institute also had three fighters with Limit Douluo-level strength-Jiang Hai, Li Qingfeng, and Jing Hongchen-as well as over a dozen fighters at the level of Titled Douluos and Level 9 Soul Engineers.
With those three sides combined, even without counting the Far North and the Ice Sea, their top experts were no weaker than Shrek's alliance with the Three Great Empires, the Star Dou Great Forest, and the various Secluded Sects. They might simply have far fewer Titled Douluos.
But a Level 9 Soul Engineer would unquestionably outperform a Titled Douluo on the battlefield.
