Li Feng absorbed spiritual energy produced by the Divine Source at a very fast pace. Those spiritual energy went to his spirit root and turned into spirit Qi of two types, Celestial Origin Qi and Sacred Divine Qi. As he was in the peak of Qi gathering relam, his Dantian did not have any space left. But still Li Feng forcefully incorporated the newly produced spirit Qi inside it.
After this, in a normal breakthrough process, the cultivator would use this new spirit Qi as a core to compress the spirit Qi that was already in the dantian. But Li Feng did not do that. Instead, he started to just normally introduce more spirit Qi in his dantian while running the Blood God Divine Scripture cultivation method.
This was actually a very dangerous thing to do. If the dantian wall was unable to withstand the pressure from inside then it would blust open. Any injuries to the dantian was extremely hard, almost impossible to heal. And with a broken dantian, the Spirit Qi would start leaking. Cultivating more was impossible in that situation and over time, the cultivation level of the person in question would also start to regress.
But with his supreme talent and powerful cultivation technique, the dantian wall of Li Feng was many times stronger than a regular dantian wall. So no matter how much extra pressure was put on it, the wall remained perfectly fine.
After the amount of spirit Qi inside had increased by about 20 percent, a sudden change happened in the dantian. Instead of the wall breaking, the size of the Dantian suddenly increased slightly. So now it was able to hold more spirit Qi and the pressure on the wall lessened.
This was an unbelievable phenomenon. No cultivator of this region were aware that the size of the dantian was not fixed. But even if they knew about this method, most of them would not be able to replicate it. That was because their dantian wall was not strong enough to withstand high pressure.
Li Feng continued to do that for almost half an hour. In that time, the size of his dantian had increased by more than 3 times compared to its initial size. Li Feng also felt that he had finally reached a hard limit and if he tried to increase the pressure anymore, his Dantian wall would not be able to withstand it. Only after reaching this limit, he finally started to compress his spirit Qi.
This process was much easier and happened very quickly. In less than 10 minutes, all his gaseous spirit Qi had turned into liquid. With his dantian's increased size, the liquid spirit Qi really looked like a sea. This was the sign of a successful breakthrough to the Foundation Establishment Realm. But the breakthrough process was not over yet.
Other than increased amount of and stronger spirit Qi, one another benefit that foundation establishment realm cultivator enjoyed was the availability of spiritual sense. With the spiritual sense, a person was able to feel everything in a large area with perfect clarity.
After the liquid spirit Qi formation was completed, a peculiar energy was created in the spirit sea. Li Feng guided that energy to his mind and immediately his senses opened up. This was how he activated his spiritual sense.
Normally this would be the end of the breakthrough process. But that was not the case of Li Feng. Normally this peculiar energy would only be produced a single time in the dantian and someone needed to cultivate a soul related secret technique to produce more. But as the Blood God Divine Scripture was a complete technique, it was capable of producing the special energy continuously.
As Li Feng introduced more and more of this energy to his mind, his spiritual sense started to become stronger and stronger. After about 5 minutes, the rapid production stopped and the growth of the spiritual sense came to a halt.
But even this was not the end. Next all the blood in his body started boiling and everything else present in his body, like his organs or bones started dissolving in his blood. This also included his mind and dantian. Soon he turned into a figure completely made of blood and only blood. Even during this process, he made sure that Yue was not disturbed in her breakthrough process.
After his whole body had turned into blood, something amazing happened. As if life getting born from the primordial sea, all the organs started to born anew from his blood. At that exact moment, Li Feng also fell into an enlightenment.
He had no idea how long this process had lasted but when he came back to his senses, the Divine Source Pill had stopped operating and he had successfully reached the foundation establishment realm. He felt the power in his body and for the first time truly realised how insanely strong his cultivation method was.
During the enlightenment, what he had comprehended was actually the Dao of life. Normally, only a Divine Transformation realm powerhouse could come in contact with Dao for the first time and only a Dao Integration realm powerhouse could comprehend it. But Li Feng was able to do that when he was just a Foundation Establishment Realm cultivator. This was something unprecedented.
Not only that but the Dao he had managed to slightly comprehend was a top tier dao like Life. Even Dao Integration realm powerhouses would have a hard time comprehending a powerful dao like this. But Li Feng did not found it to be too difficult. His cultivation method was definitely responsible for this but his own insane comprehension was also a reason why he was able to comprehend a Dao when he was only at the Foundation Establishment realm.
With this newfound power, Li Feng felt extremely powerful. So much so that he could not even judge how much stronger compared to his previous self he had become after the breakthrough. With his current strength, if the Thousand Nodes Small Sword Slaughter Formation was used against him, he would be completely unharmed.
With immense joy feeling his heart, Li Feng looked at Yue and found her to be asleep. From the aura he sensed from her body and her two tails, it was clear that she had also made a successful breakthrough. It was common for spirit beasts to sleep after their breakthrough to adjust the body with their new strength and to digest ancestral memories, so Li Feng did not worry about it too much and just waited for Yue to wake up.
That was how both of their breakthrough came to an end.
