The lakebed.
"About four years of strength growth!"
Jiang Ning had digested the twenty-year-old Thunder Fruit and slowly opened his eyes, which immediately revealed a look of surprise and joy.
For an ordinary Fifth Grade Internal Strength Realm martial artist, a twenty-year-old Thunder Fruit could only increase about two years of strength.
But in his case, it had doubled to four years.
The effect was doubled.
That meant, on him, one Thunder Fruit could be used as two.
How could he not be delighted!
The next moment.
The fifty-year-old Thunder Fruit suddenly appeared in his hand.
"Based on just now's experience, this Thunder Fruit could increase my strength by ten years!"
Thinking of this, Jiang Ning felt immensely satisfied.
Ten years of strength.
How many decades does one have in a lifetime?
Even for a Grandmaster, it's but two sexagenary cycles of lifespan.
Such a fruit equalled the ten years of strength accumulation of an ordinary Fifth Grade martial artist.
