At the same time, he knew.
This was indeed a normal occurrence.
There was no need to worry about his Nascent Soul exploding, nor did he need to worry about failing the breakthrough.
He only needed to continue pouring his divine sense into his Nascent Soul without cease.
Once all of his divine sense had been poured into the Nascent Soul and the two had truly become one.
The middle three refinements would be complete.
However.
This process was quite lengthy.
When He Song had watched Zang Jianzi do this before, he had waited for several decades.
It took Zang Jianzi several decades to completely merge his Nascent Soul and divine sense into one.
It was not because Zang Jianzi had deliberately dragged things out.
Rather, although the Nascent Soul and divine sense now appeared to have become one.
In truth.
The divine sense had merely flowed into the Nascent Soul and carved out a space within it to settle down.
As for the next stage of fusion, that would come later.
Therefore, as the divine sense entered the Nascent Soul and continued to increase with the passage of time, it naturally needed to occupy more space.
Yet the Nascent Soul was only so large.
Once the space within the Nascent Soul reached its limit, the cultivator naturally needed to manipulate the Nascent Soul and divine sense to open up more space inside it to contain the divine sense.
And it was precisely this process.
That required an enormous amount of time.

Was mainly because of this.
Therefore, having watched and remembered all of this, He Song naturally knew what he needed to do now.
However, even He Song could not avoid the time this would consume.
