Xiao Yan was at the Da Dou Shi class during the three year agreement to fight through the heavens. What kind of strength did Nalan Yan Lan have? I can see that Xiao Yan did not use his full strength. He did not even use the underground Dou Technique.

The Dou Techniques that Xiao Yan had learned were as follows: [1. Heavenly Silkworm Potato Skill: Xiao Yan's father, Xiao Yuan Shan, had once imparted this mysterious martial art to him when he was young. It could increase his strength and speed.] 2. Fire Cloud Cave Flame: A special Dou Technique that Xiao Yan had trained in the Fire Cloud Cave. It was able to unleash a fireball-like attack with astonishing might. 3. Mysterious Yang Skill: A martial art that Xiao Yan practiced in the Mysterious Yang Cave that could strengthen his physique and endurance. It was the key to Xiao Yan's survival on the Dou Qi continent. [4. Flame Tide: A Dou Technique that Xiao Yan had trained in the Flame Valley. It is able to emit a flame-like attack that can cause great damage to the enemy.] All the Dou Techniques on the Dou Qi continent: All the Dou Techniques that Xiao Yan had trained on the Dou Qi continent included the basic Dou Qi training methods, the training methods of various weapons and equipment, etc.

Nalan Yanran's strength was at the third level of the Dou Shi class in the three year agreement for the Battle Break the Heavens. Nalan Yanran was the Young Sect Leader of the Misty Cloud Sect. She was the eighth generation Sect Leader of the Misty Cloud Sect and the youngest Sect Leader in the history of the Misty Cloud Sect. She was talented and intelligent.

According to my understanding, when Xiao Yan broke the three year agreement, his strength was at the third stage of Dou Zhi Qi. Nalan Yan Lan did not reveal her strength during the battle. Later on, she displayed the strength of a Dou Huang during the battle with Xiao Yan, causing Xiao Yan to feel extremely surprised and shocked. Hence, one could deduce that Nalan Yan Lan's strength should be at least at the Dou Zhe level. As for why Xiao Yan did not use his full strength and why he did not use the underground Dou Technique, these questions could only be answered by reading novels. I recommend you to read "Battle Through the Heavens". There will definitely be more surprises and wonderful things waiting for you! I hope you like my recommendation, Mwah ~
