Background
The Blue Lightning Tyrant Dragon is a true dragon, not an earth dragon or a variant of the Tyrant Dragon. Its lineage belongs to the Silver Dragon King’s elemental-dragon line; the Tyrant Dragon belongs to the Golden Dragon King’s power-dragon line 115. The Blue Lightning Tyrant Sect regards it as its signature martial soul and has researched suitable soul-ring sources and skills across generations 4 5.
Unlike an ordinary Beast Martial Soul, possession of the Blue Lightning Tyrant Dragon gives little physical enhancement before level 30. Its distinctive strength is Dragon Transformation: power concentrates in one body part at a time rather than strengthening the whole body evenly. The sect calls it the strongest attack-oriented Beast Martial Soul 5.
Appearance
In its initial possession state, a lightning-shaped mark appears on the user’s forehead and blue-purple electricity moves across the body. Dragon Transformation replaces human features with scaled dragon parts; the Martial Soul Avatar takes the form of a blue-purple dragon 21 30 197.
- Transformed arms — enlarge and develop blue-purple scales and claws 30 250.
- Full-body form — covers the body in dragon scales and includes wings 5 213.
- Avatar — Yu Yuanzhen’s form is described as a lightning-wreathed giant dragon over a hundred meters long 197.
Abilities & Skills
Dragon Transformation
Dragon Transformation concentrates physical enhancement in transformed parts. Yu Tianlin estimates that his first transformed arm doubles its attack power, defense and strength 30.
- Usual sequence — one arm at level 30, both arms at 40, both legs at 50, torso at 60, and full body with wings and Martial Soul Avatar at 70 5.
- Further completion — the left horn transforms at Soul Douluo level and the right horn at Titled Douluo level 291.
- Soul-ring requirement — dragon-species rings supply Dragon Power. Rings lacking a dragon bloodline delay transformation; more than three such rings can prevent the user from reaching level 70 5.
- Flight — transformed wings consume less Soul Power than Yu Tianlin’s spirit-bone wings, making them better suited to prolonged flight 204.
Thunderbolt Dragon Claw
The sect identifies Thunderbolt Dragon Claw as a particularly suitable early skill. It forms a lightning claw around the hand for close combat or launches one as an explosive ranged attack, and it can be stacked with a transformed dragon arm 5.
- Yu Jian’s hundred-year version increases close-combat attack power by 50%; its projected claw can reach twenty meters 5 19.
- Yu Tianlin’s thousand-year version forms a two-foot claw and increases attack power by 100% 30.
- The scattered lightning outside the center of its explosion has only a slight numbing effect 19.
Other Sect-Favored Skills
- Thunderbolt of Ten Thousand Jun — the sect’s favored second skill, used for ranged lightning attacks 5 47 250.
- Wrath of Thunderbolt — a self-amplification skill derived from the Thunderbolt Savage Dragon. It increases Soul Power and the Power of Thunder and Lightning; its amplification varies with ring quality 71 98 172 250.
- Choice beyond the third ring — disciples can choose later skills for themselves. Yu Tianlin departs from the usual early sequence by taking Thunder Dragon Roar as his third skill and Wrath of Thunderbolt as his fourth 74 179 215.
Lightning Affinity and Domain
- Martial Soul Possession strengthens the user’s Power of Thunder and resistance to lightning 5 21.
- Yu Tianlin eventually gains a domain attached to the martial soul. His explanation for why other users had not awakened one—that low-grade Dragon Power from sub-dragon rings reduced their martial souls’ purity—is presented as his own hypothesis 198 204.
Notable Development
In Dragon Valley, Yu Tianlin absorbs blue-purple Thunder Attribute Dragon Clouds. They expel impurities associated with low-grade Dragon Power and strengthen his body and Dragon Transformation, allowing him to stop relying on sub-dragon rings for that power 114 116. Later, while fighting Qian Renxue, he experiences quality-based suppression from her Six-Winged Angel martial soul before his own evolves into the Thunder Holy Dragon 379 380 381.
