" Battle Through the Heavens " was a web novel. There was no definite answer to the strongest fighting technique in it because every character had their own unique skills and fighting style. Moreover, the strongest fighting technique could also change according to different battle situations and backgrounds. However, in the novel, there were some skills that were generally considered very powerful, such as: [1. Heavenly Silkworm Potato: This is the signature skill of the main character Xiao Yan. He can increase his fighting strength by devouring the power of the heavens and can release its strength at any time during battle. It is very powerful.] 2. Blazing Flames: This is the skill of the other main character, Yun Yun. It can release a ball of hot flames to cause great damage to the enemy. 3. Ice Spirit Silver Needle: This is the skill of Xiao Yan's father, Xiao Ding. It can create a precise silver needle to cause damage to the enemy by condensing the power of ice. 4. Heavenly Tribulation Sea of Fire. This was a skill that Xiao Yan and Yun Yun used together. It could release a sea of burning flames that trapped the enemy within it, causing continuous damage. It is important to note that these skills are only a part of the novel and not all characters have the ability to use all skills. The strongest fighting technique would still need to be determined based on the specific battle situation and character settings.
