Inside the Spirit Forging Tower.

Qin Xin arrived at the entrance to the fourth floor, where a spiritual energy barrier prevented students from entering at will.

Qin Xin gently raised the iron token given to him by Ye Nian. The power of the light screen immediately enveloped the token, and Qin Xin was also inside, slowly disappearing into the light screen.

As he passed through the light barrier, the sudden surge of spiritual energy caused Qin Xin's entire body to tremble uncontrollably. The impact of this surge of spiritual energy was so tangible that it even caused a stinging sensation in his Niwan Palace. Fortunately, the spiritual consciousness swirling on the Spirit Devouring Stone repelled all the forces that wanted to rush into his Niwan Palace.

For a quarter of an hour, beads of sweat dripped from Qin Xin's forehead, and his lips turned white, but he still gritted his teeth and refused to give up.

Unbeknownst to anyone, Elder Ye Nian was already waiting on the fourth floor of the Spirit Forging Tower. He seemed to want to see how long this young man could withstand the spiritual energy tides on the fourth floor.

At this moment, Qin Xin had no time to care about the outside world. He focused all his attention on finding ways to neutralize the spiritual energy tide.

Above the Firewood Martial Pill, the spiritual energy tides, through continuous accumulation, seemed to transform into the phantom of a giant Kun. With each breath of this giant Kun, Qin Xin could feel his soul becoming somewhat dazed.

"not good!"

The giant Kun suddenly opened its mouth and entered the Firewood Martial Core directly, even attempting to swallow Qin Xin's Black Stick Martial Spirit. This scene startled him so much that he broke out in a cold sweat.

"Spirit Stone! Absorb it!"

An imperceptible force suddenly appeared in Qin Xin's martial core, and the giant Kun seemed to be terrified of this force. When it tried to dodge, it was torn to shreds.

After the giant Kun phantom shattered, it was directly swallowed by the Spirit Devouring Stone and slowly transformed into several streams of pure power, which were directly poured into the Black Stick Martial Spirit. However, the violent spiritual energy tide did not dissipate.

"In that case, help me open up the seventh main meridian!"

Qin Xin made a bold decision and actually wanted to use the violent spiritual energy tide to break through. This daring move made Elder Ye Nian, who was observing, admire him.

"Impressive! Such strong soul power, but to think you can break through by relying on the spiritual energy tide is a bit arrogant."

Elder Ye Nian did not sense the presence of the Spirit Devouring Stone within Qin Xin's body. Instead, he attributed Qin Xin's ability to withstand the soul impact of the fourth level to his powerful soul force. However, the power of the spiritual tide was extremely violent, and he did not believe that Qin Xin could use this power to complete the breakthrough.

Qin Xin was well aware of this. With his keen spiritual perception, he carefully guided the power of the spiritual tide into his seventh main meridian. The main meridian was the place where true energy was contained, so its ability to withstand the impact of power even exceeded that of the dantian. In addition, Qin Xin's physique was stronger than that of martial artists of the same level due to the use of Danqing's exclusive secret medicine, the Meridian Tempering and Bone Strengthening Pill. Therefore, this attempt had a considerable probability of success.

For Qin Xin, he now craves even greater power, and he will try even if there is only a sliver of hope.

"hiss!"

Feeling the intense pain emanating from the seventh main meridian, Qin Xin's lips twitched involuntarily. This seventh main meridian was connected to the spine, linking all the bones in the body together through countless tiny meridians. As a result, this main meridian was thicker than the others, and breaking through it required a much greater amount of power.

For martial artists, the seventh level of the Innate Realm is like a watershed moment, and also a bottleneck period for countless martial artists. Once they can break through, entering the Aperture Opening Realm is only a matter of time. However, many martial artists get stuck here and spend several years or even decades to break through.

That is why Qin Xin guided the even more violent spiritual energy tide into his martial core to the seventh main meridian, in order to use this violent energy to solve this problem in one fell swoop.

"Click...click..."

With each surge of spiritual energy, a sound would be heard within Qin Xin's body, as if a barrier was being constantly breached.

"Is it really possible?"

Elder Ye Nian sensed the changes in Qin Xin at this moment. He continuously restrained his true energy to protect the martial core and the surrounding meridians, allowing the spiritual energy tide to continuously impact the seventh main meridian. Moreover, the barrier above this main meridian was constantly decreasing, as if it was only one last bit of power needed to break through it.

However, the power of this spiritual energy tide is limited, and it is slowly weakening under the constant impact.

"Is it going to fail?"

Elder Ye Nian also felt a little regretful, but he also greatly admired Qin Xin's courage. However, he was afraid that few martial artists at the Innate Realm would dare to try letting the violent spiritual energy surge through their bodies.

Moreover, although he failed to break through, the bottleneck of Qin Xin's seventh main meridian has been broken, and he will be able to enter the seventh level of the Innate Realm in less than a month.

"Break through!"

Feeling the weakening of the spiritual energy tide, Qin Xin was naturally unwilling. The true energy he originally used to protect his meridians and martial core was all transferred to the seventh main meridian.

"Thump!"

After a violent impact, countless bursts of true energy shot out from Qin Xin's body.

"This kid's a madman! He actually withdrew his inner energy protection!"

Elder Ye Nian, witnessing this scene, initially intended to step forward and summon Qin Xin from the surge of spiritual energy. However, upon sensing the surging true energy emanating from Qin Xin's body, he immediately stopped in his tracks.

The main reason why this true energy shot out from the main meridians is that the main meridians that the martial artist has opened are all connected. Therefore, when it violently struck the barrier of the seventh main meridian, the other main meridians were also affected.

"Click..."

A crisp sound suddenly rang out.

Several cracks appeared on the barrier of the seventh main vein, and it collapsed in an instant.

Sensing the current state of his body, Qin Xin dared not be careless. When he adjusted his true energy again, his martial spirit inhaled, instantly drawing back the true energy that had shot out from his body, and directly forcing the spiritual energy tide out of his body.

The newly opened main meridian is somewhat fragile and needs to be constantly cleansed and tempered by true qi to become resilient. If it is impacted by violent power, it is likely that the main meridian will be left with hidden ailments, which will also leave some hidden dangers for the martial artist to advance to a higher realm in the future.

When the seventh main meridian was opened, Qin Xin could feel his true energy circulating through some tiny meridians, attaching itself to the bones of his entire body. He could feel explosive power with just a light clench of his fist.

After reaching the seventh level of the Innate Realm, Qin Xin was confident that if he encountered Heng Hua again, he would be able to defeat him and escape unscathed.

After circulating true qi, not only was the impurity in the seventh main meridian expelled through the skin, but some bones were also cleansed of impurities by the true qi, making them stronger.

"call……"

Qin Xin exhaled a long breath and slowly opened his dark eyes. Suddenly, he sensed a presence not far away and immediately became wary.

"Not bad, he has guts and his soul power is also very strong."

After Elder Ye Nian nodded, he left the Spirit Forging Tower.

"Could he have discovered the Soul Devouring Stone inside me?!"

Qin Xin was somewhat worried that if this secret were discovered, it would be a big problem for him, so he asked Dan Qing in his heart.

"Don't worry, I concealed all my aura when that stone was in motion. At most, that person would think your soul is stronger. But even if he discovers it, so what? I have traveled through the Three Thousand Realms and traversed the Immortal Realm for tens of thousands of years, and I have never seen this stone before."

Danqing began to boast about his past glories, but Qin Xin felt that his words were embellished.

Relieved, Qin Xin then began to examine the structure of the fourth level of the Spirit Forging Tower.
