The first level!
With the help of a large number of breakthrough stones, or rather, he only spent a trace of breakthrough stones, not even one-ten-thousandth of a single one, and Zhu Wuwan cultivated the modified Eternal Spring Arts to the first level.
Strands of Eternal Spring Internal Strength suddenly appeared in his body. Not only was this internal strength strong and powerful, but its offensive and defensive power was also shocking. It could also effectively temper Zhu Wuyang's body, making it extremely strong.
The most important thing was that its nourishing effect was amazing. It could nourish every corner of Zhu Wuyang's body in an all-round way, causing Zhu Wuyang's body to undergo a fundamental transformation and extend Zhu Wuyang's lifespan.
Sensing the green Eternal Spring Inner Qi in his body, Zhu Wuwan smiled and continued to improve the Eternal Spring Technique.
