Chapter 421: The Late Sunagakure
After temporarily resolving the issue with Madara from Parallel World 2, Lux left, taking Tobirama from Parallel World 1 with him.
He left the situation there for Tobirama from Parallel World 2 to handle.
Since Madara had agreed, it was highly unlikely that he would break his promise; Madara, who hadn't yet reached old age, was still fundamentally a man of his word.
On the other hand, the two Tobiramas.
If Lux stayed here, there was no guarantee that the two Tobiramas wouldn't "act arrogantly" and inadvertently provoke Madara again.
This isn't to criticize them—it's human nature.
How many people wish to have a strong older brother who protects them forever, but can't have one! In the end, it's because Hashirama, as the indulgent older brother, spoiled Tobirama's nature.
After Lux and the other Tobirama left, Tobirama from Parallel World 2, who was still blind, also became more cautious.
He no longer dared to launch verbal attacks against Madara.
Of course, his stubborn lips still reflected the unyielding spirit of Tobirama.
'Hmph! After getting through this difficult time, I must develop more forbidden jutsu.'
