Immediately, Chen Feiyu gritted his teeth and directed the boundless sword intent to pour into himself crazily from top to bottom, assisting the medicinal power in his body to help him make a breakthrough.

However, Chen Feiyu upgraded to two levels in a row, and the efficacy of the "Huitian Pill" was almost exhausted. Even if he frantically guided the sword intention into his body, it would be difficult to truly break through.

Soon, Chen Feiyu was shocked to find that his momentum to attack the "late stage Xiantian" realm was getting smaller and smaller, and he was afraid that it wouldn't be long before his breakthrough would completely stop.

Just when Chen Feiyu was getting more and more anxious, suddenly an idea flashed in his mind and he had a bold idea.

I saw that after he guided the sword intent to infuse himself, he no longer assisted the medicinal power to achieve martial arts breakthroughs. Instead, he took advantage of the resonance between the sword intent in the Dantian and the "pictured world" sword intent, controlled the sword intent and medicinal power, and began to attack.

The second aperture of the "Hunyuan Sword Sutra" - the spiritual root aperture!

According to the "Hunyuan Sword Classic", after opening the "spiritual root aperture", one can reach the state of "at this time, heaven and man are integrated into one body, and the heaven and earth are ventilated".

In other words, if you can use your own energy to communicate with the energy of heaven and earth, and use the spiritual energy of heaven and earth to supplement your own spiritual energy, and achieve the state of unity between heaven and man, your own swordsmanship can be improved to a higher level, and you can easily reach the "innate" level.

"later stage" realm.

Of course, this is also Chen Feiyu's dangerous move. If he fails to open up the "spiritual root aperture", then his opportunity to break through will be wasted.

However, according to the current situation, even if Chen Feiyu continues to try to break through martial arts, he will inevitably fail. It is better to try to open up the "spiritual root aperture" and use a dead horse as a living horse doctor, and maybe a miracle will happen.

At this moment, under the constant impact of the sword intent and the power of the medicine, a small crack was quickly opened in the "Spiritual Root Aperture".

Chen Feiyu was overjoyed and immediately pursued the victory and continued to attack the "spiritual root aperture".

As time went by, the gap in the "Spiritual Root Aperture" became larger and larger, and soon half of it was opened, and under Chen Feiyu's impact, the gap continued to expand.

Just as he was about to open the "Spiritual Root Aperture", the power of the "Huitian Pill" in Chen Feiyu's body was almost gone.

Chen Feiyu felt anxious, was he going to fall short?

He gritted his teeth and thought, mobilizing the Long Yuan Sword not far away. Using the Long Yuan Sword as a medium, he mobilized the sword intention of the "pictured world" even more crazily.

At the same time, the Dantian Sword Intention, which had been nourished all the time due to the opening of the "Xuan Tong Aperture", was also pulled by the Long Yuan Sword and broke out at this moment.

Immediately, the sword intent inside and outside the body resonated more strongly, and merged in Chen Feiyu's body, forming a big river, impacting the "spiritual root aperture" with an unstoppable force.

All of a sudden, Chen Feiyu seemed to hear a sound of thunder in his ears, and his own energy circulated violently in his body.

The "spiritual root orifice" is completely opened!

Before Chen Feiyu could be surprised, a powerful aura erupted from his body again, instantly breaking through the bottleneck and reaching the "late stage innate" realm!

I saw that the huge sword intent gathered above Chen Feiyu's head gradually dissipated, and the aura around Chen Feiyu also returned to calm.

The song ends and the clouds disperse.

"I have really broken through to the 'late stage innate' state. It feels so good to be promoted to three levels in a row!"

Chen Feiyu looked overjoyed and quickly looked inside to check the situation inside his body.

I found that not only did I break through to the "late stage of innate" realm, but the "Hunyuan Sword Scripture" also opened up the "spiritual root aperture", and even the "Xianwu Hezong Jue" broke through to the high level of the third level of Xianwu in one fell swoop, and both physical and mental strength were improved.

Great strengthening!

"With such a strong mental power, even if I face a strong person in the 'Concentration Stage' now, I should be able to defeat him." Chen Feiyu clenched his fists, with a look of excitement on his face.
Chapter completed!
