As expected, the universe gourd could hold the lightning water.
In the blink of an eye, all the lightning water was emptied and a thunder essence crystal was exposed at the bottom of the pool.
The crystal was translucent and was covered with purplish lightning which flickered continuously.
Looking at the crystal, Yu Nianzhen felt a pain in his eyes and a terrible pain flashed in his head.
Without meaning to, Yu Nianzhen groaned and subconsciously closed his eyes to block out the sight of the crystal.
"What's wrong?" Jiang Yue asked when he heard his husband's groan.
"It's okay." Yu Nianzhen answered and opened his eyes.
"I didn't expect the thunder essence crystal to be so domineering." He continued and sighed.
Fortunately, he didn't look at the crystal for too long or he would have endured worse pain.
After putting away the universe gourd, Yu Nianzhen took a deep breath and thought about the current problem.
