Not long after the five Corpse World experts had left, Ye Yunfei and Situ Kong'er reappeared in the distance.
"There really are quite a few Corpse World experts stationed within the Land of Life and Death," Ye Yunfei said, frowning as he looked in the direction the five experts had departed.
Those five Corpse World experts were all at the late stage of the Tribulation Birth Realm!
That was exactly why Ye Yunfei had avoided them earlier.
Ye Yunfei knew that with his current strength, fighting five late Tribulation Birth Realm experts would be a bit of a stretch.
Although the strength of his Blood Clan Clone was roughly equivalent to the late Tribulation Birth Realm, or even stronger, facing five at once meant that if a fight broke out and he couldn't achieve a quick victory, it would inevitably attract even more Corpse World experts.
Of course, if a real fight did occur, Ye Yunfei was confident that even if his side couldn't win, they could still retreat calmly.
"Brother Situ, let's switch up our approach for the next phase," Ye Yunfei said after a moment of thought.
"What approach?" Situ Kong'er asked.
"We'll quietly infiltrate the ranks of the Corpse World forces. We'll subdue everyone below the Primordial Chaos Realm and capture all those at the Origin Creation Realm. Then we'll settle accounts with those at the Tribulation Birth Realm."
Ye Yunfei believed that with his current Soul Power level, he could now attempt to use the Puppet Soul Thread Secret Art to subdue Origin Creation Realm cultivators and turn them into slaves.
"Great! Brother Su, we'll do as you suggest!" Situ Kong'er said, his interest piqued.
"Brother Situ, you first infiltrate the Corpse World forces and investigate the exact locations of all the Corpse-Nurturing Lands they have within the Land of Life and Death. Then we'll wipe them out in one fell swoop. The Corpse World has operated here for so long and built so many Corpse-Nurturing Lands. It will surely pain them greatly if they are all destroyed," Ye Yunfei added after further consideration.
"Makes sense! Let's do it that way. I'll infiltrate their ranks, find out the specific locations of all their Corpse-Nurturing Lands, and then we'll act," Situ Kong'er replied, his spirits visibly lifting at Ye Yunfei's words.
"Good. I'll go into closed-door cultivation for a while first," Ye Yunfei said.
"Alright," Situ Kong'er nodded.
Next, Ye Yunfei entered the Phantom Tower. Situ Kong'er, meanwhile, continued forward to search for the Corpse World's strongholds in the peripheral regions of the Land of Life and Death.
Inside the tower, Ye Yunfei took out a large batch of soul-related cultivation resources and began refining and absorbing them to enhance his Soul Power.
Ye Yunfei had just killed six Tribulation Birth Realm experts and captured a large group of Corpse World personnel, including many at the Dao Yuan Realm, Primordial Chaos Realm, and Origin Creation Realm. Naturally, all their possessions had fallen into his hands.
The Corpse World was one of the strongest superpowers in the Central Divine Land, so its experts were naturally quite wealthy, possessing large quantities of cultivation resources. Now, all these things belonged to Ye Yunfei.
Whoosh...
The Soul-Nurturing Tree rushed out from Ye Yunfei's soul sea, spreading out a large number of roots and branches to begin refining and absorbing the soul energy contained within the resources piled up around him.
One month later inside the Phantom Tower, Ye Yunfei had fully refined and absorbed all the soul-related resources he possessed.
His Soul Power level had increased significantly!
"Kid, the seals inside some prisoners on the second level of the Heavenly Dao Tower have acted up again!" Suddenly, Ye Yunfei received a voice transmission from Hun Lao.
"Good, I'll go in and take a look," Ye Yunfei said, immediately entering the second level of the Heavenly Dao Tower.
Ye Yunfei was precisely in need of cultivation resources at this time. The mysterious experts imprisoned on the second level of the Heavenly Dao Tower each had abundant assets, making this a perfect opportunity to extort them.
Sure enough, the seals within three experts on the second level were acting up, causing them to howl in agony.
The prisoners held on the second level of the Heavenly Dao Tower were all terrifyingly powerful. However, imprisoned here by the Ancient Desolate Heavenly Emperor with seals planted within them, these seals would flare up periodically, subjecting them to inhuman torment.
After some extortion, Ye Yunfei managed to obtain a large batch of precious cultivation resources from those three experts.
This naturally included many soul-related treasures.
He even got a batch of Time Crystals.
One must understand that the ancient era of the Three Thousand Greater Worlds possessed far more cultivation resources than the present!
After extorting the resources, Ye Yunfei began closed-door cultivation again.
Gradually, Ye Yunfei's strength in all aspects continued to improve.
This included his Soul Power level, spiritual energy intensity, as well as his attainments in Time Energy and Space Energy.
Unbeknownst to him, a year passed within the Phantom Tower.
"I'm about to break through!" Ye Yunfei suddenly sensed the opportunity for a breakthrough.
Next, Ye Yunfei began to assault his spiritual energy realm.
After another half a year or so, Ye Yunfei broke through several times consecutively, reaching the mid stage of the Primordial Chaos Realm in one breath!
In fact, for Ye Yunfei, there were no bottlenecks in his cultivation breakthroughs regarding spiritual energy realms. Having been a Heavenly Emperor in his previous life, the level of enlightenment he had attained was profound.
To put it this way: if Ye Yunfei were supplied with sufficient energy, he could, at the very least, break through to the Semi-Heavenly Emperor Realm in one go!
Only when attempting to assault the Heavenly Heavenly Emperor Realm again would it be somewhat more difficult.
After all, the great Dao laws of the Three Thousand Greater Worlds imposed restrictions, dictating that the number of Heavenly Emperors in a single era was limited.
One could draw this analogy: the cultivation of ordinary martial artists in the world was akin to starting as an infant, constantly growing and maturing step by step into an adult, representing different stages of growth for a person.
Ye Yunfei, however, was originally a colossus who stood between heaven and earth. It was just that after experiencing a great calamity, only his skeleton remained. He merely needed to refill it with flesh and blood, and he could quickly restore himself to his former sky-propping, earth-supporting form!
This was precisely why Ye Yunfei, when breaking through in spiritual energy realms, could often advance several minor realms, or even a major realm, at once!
The reason Ye Yunfei had been suppressing his spiritual energy realm, not rushing to break through, was mainly to prepare for his future assault on the godhood tribulation.
When undergoing the godhood tribulation in his previous life, Ye Yunfei had realized that his spiritual energy foundation and physical body quality were not solid enough. Even if the other three Heavenly Emperors hadn't taken the opportunity to ambush him, he might not have been able to successfully pass the tribulation.
Therefore, in this life, Ye Yunfei had learned from experience. Not only had he spent a great deal of time and effort tempering his physical body, but he had also deliberately polished his spiritual energy foundation.
"Mid Primordial Chaos Realm. My current spiritual energy intensity is roughly equivalent to the late or even perfected stage of the Origin Creation Realm. Relying on spiritual energy alone, I can now put up a fight even against Tribulation Birth Realm experts." Ye Yunfei clenched his fist, sensing the intensity of the spiritual energy within his body, and muttered to himself.
"Alright. With my current Soul Power intensity, I should be able to use the Puppet Soul Thread Secret Art to subdue those at the Primordial Chaos Realm."
Inside the Phantom Tower, a batch of martial artists at the Primordial Chaos Realm were imprisoned, most from the Corpse World, with a small portion from the Tianyou Tomb.
In the following period, Ye Yunfei began attempting to use the Puppet Soul Thread Secret Art to subdue these Primordial Chaos Realm cultivators.
A little over half a month later, all the Primordial Chaos Realm cultivators had been subdued, becoming slaves.
There were roughly two hundred of them.
Added to the Dao Yuan Realm slaves he had subdued earlier, most of whom had already broken through to the Primordial Chaos Realm under Ye Yunfei's assistance, the number of Primordial Chaos Realm slaves under Ye Yunfei's command now reached over six or seven hundred!
This was a truly considerable force!
