The speed of the 'Red Thunder Chariot' was no less than that of 'Nine Heavens Ten Earths Pimo Divine Shuttle', but the space inside it was much narrower, and it couldn't be used as a weapon against the enemy.
That's why the latter is considered an immortal treasure, while the Red Thunder Chariot is merely a 'pseudo-immortal treasure'.
However, it was enough for travelling. Inside the chariot, there was a slight awkward air between Princess Changle, Yu Hongchang and Luo Yan, as they sat face to face.
The two women had crossed swords several times and didn't wish to instigate conflict. However, the chariot was so small yet it had to accommodate a Fumo Vajra and a Jade Qilin, making them sit uncomfortably close to each other. Both women were less than three feet apart, their breaths intermingling, each one feeling uneasy as they watched the other.
