"The color of my soul power is blue?" Lin Sheng took a peek at the ball.
As more soul power was being injected, the pressure needed was getting higher. The force-field ball could stand it, but he needed to use bigger pressure to inject the soul power into the ball.
Soon, he had finished injecting two force-field balls with soul power. Then he increased it to three, four, five, six…
As Lin Sheng increased the amount of soul power, the color of the force-field ball became dark in blue, like the color of the ocean and a cold crystal.
Finally, a soul power shot out of his hand like a laser beam, scraping past his face, leaving behind a very shallow cut on his skin.
"Twelve times the soul power!" Lin Sheng stared at the navy-blue force-field ball. Quickly, he sealed it.
"Next, it's time to do the compression."
