"Crack crack crack!"

Ye Zichen's physical body, which had reached the middle rank Saint Treasure level, was difficult to destroy. However, when he was attacked by the giant millstone, a crack immediately appeared in his flesh, causing a large amount of blood to spurt out uncontrollably, turning him into a bloody figure.

His flesh continued to crack as a huge pain spread throughout his body. However, Ye Chenfeng, who was sitting on the floor, did not let out a single cry, as if it was not his body that was being crushed.

If Ye Chenfeng could endure for three days, then with his cultivation of a 2-star Dao Lord, he would definitely be able to obtain unimaginable benefits and would also be able to greatly increase his strength.

"Persevere, persevere!"

His physical body was continuously being grinded to bits, the inhuman pain caused him to be tortured to death, but Ye Chenfeng did not retreat. He clenched his teeth and endured bitterly, using all of his strength to refine the pure energy flowing into his body.

"Just what kind of treasure is this millstone? It contains the purest of pure energy, far surpassing even that of a top grade saint pill!"

Feeling the rapid increase in his strength, Ye Chenfeng experienced the benefits of tempering with the millstones. He had a feeling that if he could endure for a few more days, then his strength would rise to a whole new level.

"Spiritual Pearl of Life, fuse!"

In order to lessen the physical pain, Ye Chenfeng had to endure it as he continuously fused with the power of the drop of the Spiritual Pearl of Life to restore his broken body.

Very quickly, two days passed.

After two days of excruciating pain, Ye Chenfeng's bottleneck began to loosen up. He bit his pale lips and continuously attacked the 3-star Dao Lord realm.

After hundreds of continuous assaults, he finally broke through his bottleneck and reached the 3-star Dao Sovereign Realm.

"Not bad, not bad! He broke through to the 3-star Dao Sovereign Realm!"

The moment Ye Chenfeng made a breakthrough, Taiyi opened his pale eyes and revealed a faint smile.

"The pain is getting stronger!"

After breaking through to the next realm, Ye Chenfeng did not even have the time to be happy when he suddenly felt the grinding power gradually increase. The huge grinding power continued to tear his body apart, tempering him in the deepest parts, causing him to tremble in pain.

"Hu hu!"

He took a deep breath and relied on his unyielding conviction to persevere until the end.

"Three days, four days, five days …"

When Ye Chenfeng was on the verge of collapsing for five days or so, his strength had increased to the peak of a 3-star Dao Lord, which gave him the opportunity to break through.

However, for a Dao Sovereign, every breakthrough was incredibly difficult. Even with the tempering of the millstone, it would be difficult for him to break through to the 4-star Dao Sovereign Realm in a short period of time.

"Nine Transformation Divine Transformation!"

Ye Zichen thought about it for a moment, then quickly used the Nine Transformation Divine Transformation to refine the huge and pure energy in his body into the Yongquan Death Acupuncture Point. Then, he changed the Astral Bead in the Yongquan Acupuncture Point and charged towards the second level of the Spirit Body.

Soon, six days had passed.

"This kid is really a monster. With his Dao Sovereign cultivation level, he was actually able to persevere for such a long time. He's really scary!"

The Lord of Darknorth still felt a lingering fear when he thought of the pain he had endured on the sixth day. If he was to experience it again, he might not be able to muster the courage to endure the tempering.

Time passed on the sixth day and it was now the seventh day.

The Supreme Bead in Ye Chenfeng's Yongquan transformed into a stronger Profound bead. At that moment, Ye Chenfeng's physical body also underwent a qualitative change. Not only did his physical strength increase bit by bit, his physical strength also reached the limit of a medium-grade saint treasure.

"Not bad, he's even more outstanding than I imagined!" Looking at Ye Chenfeng, who had endured to the seventh day, Taiyi revealed a rare smile and said, "Alright, I'll give you another opportunity. Whether you can grab it or not will depend on whether you can persevere."

As he spoke, a drop of white spirit liquid appeared on the tip of his fingers.

Although this drop of spirit liquid was only the size of a fingernail, it weighed hundreds of millions of jins.

"Go!"

With just a thought, the drop of white spirit liquid flew into the millstone that was constantly increasing its grinding speed. It was slowly ground up by the millstone, releasing pure energy and entering Ye Chen's body.

"AHH!"

The moment the white spirit liquid entered his body, Ye Chenfeng was unable to endure it any longer. He let out a painful howl, and his tense mind was about to collapse.

"No, I can't give up. I can still hold on!"

Ye Zichen bit his lips and maintained his heart, while trying his best to not let himself faint, while allowing the mountainous white energy to enter his body.

He endured bitterly for more than two hours. Cracks appeared on the bottleneck of his tough cultivation. When he was on the verge of collapsing, Ye Zichen broke through and reached the 4-star Dao Lord realm in one go.

"It's already two realms, I want to see where your limit is!" The smile on Taiyi's face became even wider.

After witnessing Ye Chenfeng's beyond ordinary endurance, unyielding conviction, and potential of the primordial blood, he had no doubt that Ye Chenfeng's future accomplishments would not be any worse than his own.

However, the spirit liquid that surged into his body was too heavy, causing his physical body to be unable to endure it any longer. He could only continue to circulate his Nine Transformation Divine Shift, refine it into his Shanzhong acupoint in his chest, and transform it into his third Supreme Bead.

"Senior, do you think he can still break through?" The Lord of Darknorth was also disappointed by Ye Chen's tenacious willpower. He turned his head and asked.

The lucky chance I gave him just now was a drop of 100 million Jun Water that I obtained in the Heavenly Realm. If he could last another day, then with the power of 100 million Jun Water, he should be able to make another breakthrough. But I know the pain of refining 100 million Jun Water. Taiyi said.

"What, what kind of energy is this!"

After fusing with a large amount of water of fifty million kilograms, Ye Zichen found it difficult to breathe. At that moment, he felt like he was being pressed down by a towering mountain, as if his bones would shatter at any moment.

However, he knew that this kind of opportunity was hard to come by. Although he could do whatever he wanted in the Soul Dueling Continent, but in the vast Heavenly Domain, he was nothing. So, he had to seize the opportunity that was bestowed to him and continuously increase his strength.

"Buzz!"

The astral bead in his Shanzhong acupoint trembled. After absorbing the energy of millions of jins of water, the third astral bead had evolved into a profound bead, while Ye Zichen's physical body had also surpassed that of a medium-grade saint treasure and reached the level of a high-grade saint treasure. As for his physical body, it had also reached an astonishing strength of 800 million jin.

Not long after Ye Zichen cultivated to the third level of the Astral Body, he managed to refine enough millions of jins of water to make another breakthrough. The moment he fainted, he successfully broke through to the 5-star Dao Lord realm, causing a qualitative change in his strength and physical body.
