When you put the Earth Core Stone Milk into your mouth, it feels a little cool, but it is also very smooth and warm.

The vast spiritual energy of heaven and earth suddenly melted in his mouth and rushed directly towards the martial core below.

"hiss!"

A sudden, intense heat surged through his meridians, causing Qin Xin to cry out in pain.

Without any hesitation, Qin Xin activated the Desolate God Battle Body, and the blood energy around his body suddenly burst forth.

The spiritual energy of heaven and earth within the Earth's core stalactite was redirected through the operating circuit of the Desolate God Battle Body, and streams of desolate energy continuously entered Qin Xin's body from the void.

With his arms already tempered by the desolate energy, Qin Xin now set his sights on his torso. Although tempering his torso would require even more desolate energy, once completed, it would greatly enhance his physical body.

With his eyes tightly closed, Qin Xin endured the stinging pain from the constant impact of the spiritual energy of heaven and earth, as well as the tearing sensation as the desolate energy strengthened his body. For a moment, Qin Xin couldn't even feel the existence of his own body.

My whole body felt numb.

"puff!"

As Qin Xin's blood energy suddenly erupted, his body seemed to break through some kind of shackle, and his blood energy surged rapidly.

"call!"

Qin Xin exhaled a long, gray breath, and his face instantly regained its color.

After being circulated by the Earth's core stone milk, Qin Xin's meridians have been strengthened and become more resilient. Now, there is a faint white aura flowing through the bones of his torso, seemingly due to the strengthening effect of the desolate energy.

After standing up, Qin Xin threw a punch, and a massive surge of blood energy instantly erupted from his fist.

"Tsk tsk! With such physical strength, he might be able to contend with a level four demonic beast."

Feeling the immense power emanating from his body, Qin Xin's face was full of smiles.

Just as he was about to take out a drop of Earth Core Stone Milk to enhance it again, Qin Xin suddenly discovered that the jade bottle in front of him was empty.

"What's going on? Did I use all these stalactites from the Earth's core?" Qin Xin wondered.

There was no one else in this futon space, but if Qin Xin were to use up all of this bottle of Earth Core Stone Milk, he would probably explode and die.

Still harboring a skeptical attitude, Qin Xin took out another bottle of Earth Core Milk.

However, this time, Qin Xin had a backup plan, leaving a trace of his spiritual consciousness on the bottle of Earth Core Stone Milk.

After taking out a drop of Earth Core Stone Milk and swallowing it, Qin Xin continued to strengthen his body. However, this time the effect was much weaker than the first time. His meridians did not receive the expected strengthening, and the improvement of the Desolate God Battle Body was negligible.

"Hmm? I caught you!"

Sensing the fluctuations emanating from the jade bottle, Qin Xin immediately opened his dark eyes.

The scene that appeared before his eyes left Qin Xin speechless with astonishment.

The round, ancient phoenix egg suddenly floated up, surrounded by a powerful, multicolored aura.

The Earth Core Stone Milk in the jade bottle was absorbed directly by the ancient Heavenly Phoenix Egg like a stream of water, under its slight ripples.

Qin Xin wanted to stop it, but it was too late. After consuming the entire bottle of Earth Core Milk, the Ancient Heavenly Phoenix Egg emitted a slight fluctuation, as if it were burping.

"Ah! My Earth Core Milk!" Qin Xin's face darkened instantly when he saw that his Earth Core Milk had been snatched away by this ancient Heavenly Phoenix Egg.

However, Qin Xin quickly calmed down. Looking at the even more powerful five-colored misty aura above the ancient phoenix egg, he realized that the Earth Core Stone Milk would be of some help in the hatching of the ancient phoenix egg.

However, he didn't have much Earth Core Stone Milk left, and two bottles had been secretly absorbed by this Ancient Heavenly Phoenix Egg, so Qin Xin didn't take any more out.

Watching the ancient phoenix egg slowly dissipate the colorful mist surrounding its shell after it had eaten its fill, Qin Xin sighed helplessly, "Sigh, I guess I'll just have to accept my bad luck. It seems I should stay away from this egg in the future when I have something good."

After Qin Xin uttered his soft murmur, the ancient phoenix egg seemed to understand, and trembled slightly, expressing its opposition.

With a thought, Qin Xin flashed away from the space of the Heavenly Phoenix Futon.

Qin Xin, sitting cross-legged on the bed, was still saddened by the loss of two bottles of Earth Core Stone Milk, but the thought of the Fire Spirit Spikes he would soon harvest eased his sorrow considerably.

After taking out the remaining fruit of the Fire Spirit Spike, Qin Xin did not consume it directly, but instead chose to put it into the Blazing Black Iron Furnace.

In an instant, orange light shone throughout the room. Qin Xin also added the roots of the Fire Spirit Spike, and the fragrance filled the entire room.

Even Qin Xin couldn't help but swallow.

Once the alchemy furnace was opened, the fruits of the Fire Spirit Spike had become much softer and more glutinous after being roasted by the flames.

Although Qin Xin only took out one fruit from the Fire Spirit Spike, after being roasted by the flames, it shed its outer shell, and the white flesh was about the size of a fist.

Unable to resist any longer, Qin Xin disregarded the heat and began to devour the fruit of the Fire Spirit Spike.

The soft, glutinous texture lingered in his mouth, and the fragrant aroma seemed to elevate Qin Xin's spirit, leaving him feeling warm and incredibly comfortable.

Soon, the entire fruit of the Fire Spirit Spike entered Qin Xin's stomach and was completely transformed into spiritual energy. After being refined by the Martial Spirit, it was transformed into pure true energy and gathered within the Martial Core.

"Huh?"

Just as Qin Xin was conducting an internal examination, he seemed to discover something.

The spiritual senses surrounding the Devouring Spirit Stone had grown considerably stronger, and Qin Xin was filled with doubt, "Could it be Earth Core Stone Milk?"

Qin Xin quickly dismissed the idea, because his spiritual consciousness hadn't changed when he left the Heavenly Phoenix Futon space. The only explanation was the fruit of the Fire Spirit Spike.

"Could it be that the fruit of this Fire Spirit Spike can help spiritual cultivators?" Qin Xin wondered to himself.

Previously, Qin Xin had read some simple records about spiritual cultivation in some ancient books of the Tianyuan Qin Clan. Among them, it was said that spiritual cultivators do not eat mortal things, but eat spiritual medicines and fruits, so as to ensure the purity of the body and prevent it from being contaminated by mortal things.

Qin Xin originally wanted to take another pill to confirm his suspicions, but he already felt very full, and if he took another one, he was afraid he would cause problems.

After abandoning the idea, Qin Xin glanced out the window and realized that it would still be quite some time before dawn.

After calming his mind again, the martial spirit within his body quietly began to circulate, and he slowly entered a state of cultivation.

Qin Xin, who is now at the ninth level of the Aperture Opening Realm, can be said to have entered a bottleneck period. The true energy in his body has been accumulated to the point that he can merge the true apertures at any time to achieve the unity of the nine apertures. However, Qin Xin is not in a hurry, but continues to accumulate power.

Although a martial artist's strength will be greatly enhanced after entering the Qi Sea Realm, and they can also condense a true qi armor, there is still a big difference in strength between martial artists in different Qi Sea Realms. This is related to the size of the qi eye that is condensed when the martial artist's meridians are fused.

Only when the Qi Eye is condensed, supported by powerful spiritual energy of heaven and earth, will the condensed Qi Eye be larger, enabling the martial artist to possess formidable strength immediately after entering the Qi Sea Realm.
