The twenty-first day.
Lin Feng's power of qi and blood had strengthened by several degrees.
He began trying to apply the power of qi and blood to his fist techniques.
With one punch, qi and blood surged forth, its power several times greater than before!
The twenty-fifth day.
Lin Feng's power of qi and blood was now able to cover his entire body.
His physical body had been tempered by the power of qi and blood, becoming even tougher.
Ordinary blades and swords could no longer harm him in the slightest!
The thirtieth day.
Lin Feng encountered a bottleneck.
No matter how he cultivated, his power of qi and blood could no longer grow stronger.
He knew he had reached his limit.
He needed a breakthrough.
But how was he supposed to break through?
He did not know.
He could only keep trying again and again.
Striking at it again and again.
The thirty-fifth day.
The bottleneck remained.
Lin Feng was becoming somewhat restless.
But he did not give up.
He recalled Elder of Scripture Transmission's words—
The foundation was the most important part of cultivating the Titan Bloodline.
Without a solid foundation, nothing else could be discussed.
"Is my foundation... still not solid enough?"
He muttered to himself.
Then, he gave up trying to break through the bottleneck.
Instead, he began polishing his foundation anew.
Again and again.
Again and again.
The fortieth day.
Lin Feng's foundation had been tempered into something incomparably solid.
Although his power of qi and blood had not grown stronger, it flowed more smoothly.
More perfectly.
And amid this repeated tempering, his cultivation steadily advanced from the early Dou Ling stage into the middle Dou Ling stage.
The forty-fifth day.
An uninvited guest came to Lin Feng's cultivation chamber.
Zhou Yuan.
The core disciple
