Li Mochou's inner energy is deeper than HIS YG?

　这幺一来，变成李莫愁和杨过合力，协助小龙女通关冲穴。李莫愁所习招数虽不如杨龙二人奥妙， 但说到功力 修为，自比他二人深厚得多。小龙女蓦地里得了一个强助，只觉一股大力冲过来，「膻中穴」豁然而 通，胸口热气 直至丹田，精神大振，欢然叫道：「好啦，多谢师姊！」松手放脱杨过右脚，跃下寒玉床来。






"but when it comes to energy cultivation, Li Mochou is much deeper than theirs (Xiao Long nu and Yang Guo)."

i dont have problem if Li Mochou inner energy > Xiao Long Nu, but it is also said deeper vs HIS Yang Guo?
