To be honest, if Yu Xiu's lifespan hadn't exceeded ten thousand years and his life level hadn't undergone a transformation, he might not have been able to complete the Taiyi Nirvana Technique.
No matter how high his comprehension, it would still have been troublesome.
He had never encountered this kind of secret technique before, and the Taiyi Nirvana Technique was so badly damaged that completing it would be no different from creating it from scratch.
To rely on comprehension that had surpassed ten thousand and forcibly complete the technique, he could only keep trying and making mistakes.
If he was lucky, perhaps he could complete it in just a few days.
If he was unlucky, it might take several months, or even a year.
In short, completing it was possible, but it would take time.
But now, he didn't need to.
His lifespan had exceeded ten thousand years, and his life level had transformed. Even without learning a secret technique like the Taiyi Nirvana Technique, he should be able to regenerate severed limbs and internal organs.
After all, his transformed life force was vast enough.
It was no exaggeration to say that even without this damaged Taiyi Nirvana Technique, Yu Xiu could now create a similar secret technique from scratch.
It was simply easier to complete the Taiyi Nirvana Technique.
Ignoring Elder Liao's trembling from sheer excitement, Yu Xiu focused all his attention on the Taiyi Nirvana Technique.
As expected, this secret technique is also connected to the Life Spring. At its root, it still depends on the transformation of life force!
But his life force and Life Spring had transformed because his lifespan had exceeded ten thousand years, a quantitative change that had brought about a qualitative one.
Clearly, Liao Jianshu's lifespan could never exceed ten thousand years. Even
