Heartburn Seal
The Flying Heaven Gate and the Soul-Stealing Gate vied for the honor of being Kongtong's face. To achieve quick results, they did not shrink from drinking poison to quench their thirst, using Fire Scorpion Poison to boost Internal Force and force a breakthrough past their bottlenecks.
Wielding the Heartburn Seal briefly speeds up the heartbeat, drives the blood, and at the cost of burning away one's remaining lifespan, raises every physical ability across the board.
But that is not the whole price. The fire poison accumulates in the body, and whenever it reaches its peak it spills out into visible symptoms: at best a dry mouth, bleeding gums, insomnia and irritability; at worst the fire rushes to the brain, and one either turns feeble-minded or drops dead on the spot.
The Dragon Boat Festival each year, when Yang Qi is at its strongest, is especially dangerous. One must be careful.

Acquisition
- Year 2 studying at the Kongtong Sect – Flying Heaven Gate Kongtong Seasonal Trial three-win reward (Yu Xiaomei goodwill ≧20)
- Year 3 marriage proposal – study at the Flying Heaven Gate, defeat Venerable Golden Crow, gifted when Yan Jiang dies: the script has this scene, but the current version's condition is set wrong, so in practice you only get Immortal Crane's Elusive Fist.
Notes
- The secret art of the Flying Heaven Gate.
- The Heartburn Seal was originally an upright, open practice. If one can calm the mind and follow the steps, drawing in the summer heat and tempering the organs, success will come in time.
- Because the Flying Heaven and Soul-Stealing Gates fought so fiercely, the seniors of the Flying Heaven Gate devised a quick method: taking Fire Scorpion Poison to force the heat up and scorch the organs. If one can endure the great trial without dying, one succeeds.
- But disciples who train by this method, nine out of ten, die young.
- The Heartburn Seal only takes effect in battle when Yin and Yang ≧60 (Lesser Yang, Greater Yang). Training the Mysterious Candle Heart Sutra lowers Yin and Yang by 1 per Level (a total of −10 when fully trained); once Yin and Yang drops below balance (＜60), it stops working.
Yu Xiaomei Story Connections
- If Zhao Huo obtains the Heartburn Seal at the Flying Heaven Gate Seasonal Trial, Xiaomei advises against training it, and tells him of its risks and price, and of Fire Dragon Immortal Monarch's true purpose.
- Xiaomei was extraordinarily gifted and did not drop dead on the spot; with Fire Dragon Immortal Monarch circulating qi to guide the fire power, she finally achieved complete success.
- But her organs were already damaged, leaving endless trouble. Every time she circulates qi her heart burns with unbearable agony; in the long run it shortens her life, in the short run she risks sudden death. She cannot fight for real at all, which is why never circulates the Heartburn Seal when trading blows with anyone.
- In the incident of the assassination of Tang Buyi, when Xiaomei/the Lady Thief deals with Zhao Huo, she rarely does circulate the Heartburn Seal in real combat.
- Xiaomei trained the Heartburn Seal not only to raise her Power quickly, but also in the hope that it would destroy the poisonous worms of the Corpse Heart Pill. Unfortunately, the latter never came true.
- During her visit to Jinxiang Palace, Painting Immortal risked herself to privately give her the Mysterious Candle Heart Sutra, hoping Xiaomei could offset the Fire Scorpion Poison.
- During the struggle for the sect leadership, Xiaomei tried to circulate the Heartburn Seal in a tree high on the mountain opposite Banyu Terrace, and leap down with the Blazing Flying Heaven Kick to perish together with Venerable Golden Crow.
