This was an unexpected development that occurred as the Reincarnation Seal reached completion.
In the final step of forming the seal, the vast reserves of Ryūmyaku chakra were not only sealed into Izumi's body. A considerable amount also poured into Kushina and Naruto, who were within the seal as well.
Still, this was not entirely unexpected. Ryūmyaku chakra had always carried the potential for this problem, and Minato had taken it into account when setting up the seal.
Uchiha Izumi had mentioned before that the newborn Uchiha children had all developed some degree of compatibility from being born under the influence of Ryūmyaku chakra. Some children had not even been born here, but as their chakra grew, their bodies were also affected by the Ryūmyaku chakra.
Minato therefore deduced that, after running wild for nearly several years and being guided through more than ten days of work on the Reincarnation Seal, the Ryūmyaku chakra might well have caused Naruto's body to develop a similar compatibility, affecting him in turn.
But compared with Naruto's own enormous chakra reserves, that influence should have been negligible—
At least, that was how it should have been.
What no one had expected was that this compatibility would draw in such an enormous amount of Ryūmyaku chakra!
Even the contingency Minato had prepared failed to fully serve its purpose. Ryūmyaku chakra surged in wildly, like floodwater bursting through an open sluice.
Even Minato had been forced to try to shoulder some of the pressure for Kushina and Naruto, only to end up affected by the relentless influx of Ryūmyaku chakra himself.
While observing the sealing process, Minato kept feeling that the Ryūmyaku chakra practically washing through Naruto's body was not entering because of some external influence. Rather, it was as though Naruto's body had thrown its
