Luo Feng was quite surprised, being so close and yet he hadn’t noticed at all.

In terms of realm and probing secret techniques, Luo Feng believed he was already quite proficient!

“I purchased a secret treasure in the Dark Sacred Realm to conceal and hide myself, which allowed me to evade the sensory perception of the Transcendent-level Mind-Bewildering Worm!”

Lord Yuanxiang solemnly said, “Luo Feng, the situation is grim. That Transcendent-level Mind-Bewildering Worm and a group of leaders are constantly attacking and killing the Elders. You must quickly refine this ‘City Building Seal’!” A black seal appeared in Lord Yuanxiang’s hand!

Luo Feng’s heart jolted. Killing low-level Chaotic Source Lifeforms could accumulate Battle Merits! Sufficient Battle Merits could be exchanged for world-level Chaotic Source Lifeform materials, corpses of high-level Chaotic Source Lifeforms!

“Secret Treasures,” “Rare Treasures,” etc.!

Even treasures comparable to the Star Tower and the Eye of Creation and Destruction could be exchanged. Among them, the City Building Seal, as far as Luo Feng knew, required a full 2 million Battle Merits to exchange for, which could be used to build a stable city!

At the same time, the city builder also needed to rally enough Elders to build the city together!

Even at the most common acquisition price of 10,000 Chaotic Source Crystals per Battle Merit, 2 million Battle Merits would require 20 billion Chaotic Source Crystals!

What’s more… it was very difficult to acquire such a massive amount of Battle Merits!

Luo Feng felt that this City Building Seal was too hot to handle! City builders would not give the City Building Seal to other cultivators!

“Don’t hesitate! While you hesitate, more Elders will be killed!” Lord Yuanxiang urged Luo Feng. “If the city is breached and Rain Ripple City is destroyed, then everything will be in vain!” Hearing this, Luo Feng immediately reached out and took the black seal!

“Refine it quickly!” Lord Yuanxiang urged.

Holding the black seal, Luo Feng began to refine it!

Seeing this, Lord Yuanxiang felt a lot more relaxed, as if a heavy burden had been lifted!

Watching Luo Feng refine the City Building Seal, Lord Yuanxiang also said,

“Luo Feng, I have cultivated all the way to the pinnacle, even in the Dark Sacred Realm. I have accumulated massive Battle Merits and numerous treasures over countless years. After my soul was corrupted… I only have one goal left: for my mind and will to break free from the cage!”

Only by breaking free from the cage could one ignore these corruptions!

“Buying this City Building Seal was also to try a different kind of cultivation life, hoping it would help my mind and will!”

“Since the establishment of Rain Ripple City, my mental corruption has become increasingly severe. I find it difficult to even bear the burden of the formations!”

Lord Yuanxiang looked at Luo Feng. “But I also have feelings for Rain Ripple City. Only today have I found a successor! I believe you are more suitable than me to protect this Rain Ripple City!” Lord Yuanxiang said.

“I will continue to control the formations until this battle of Rain Ripple City is completely over! Then I will completely let go, and all my energy will be used to resist corruption!”

“As long as you’re alive on the path of cultivation, there is hope!”

Luo Feng said, “You have succeeded in refining it?”

Lord Yuanxiang noticed and revealed a look of joy!

Luo Feng nodded slightly. “After refining the City Building Seal, I feel that I can mobilize a very large amount of energy from the entire Rain Ripple City to strengthen myself!”

“The City Lord, the Palace Lord, and the Elders can all mobilize the city’s energy, but the proportion they can mobilize is different!” Lord Yuanxiang said, “More than 90% of my mind is focused on fighting corruption, and I can barely maintain the formations, so mobilizing the city’s energy is naturally even more difficult!”

Having refined the City Building Seal, Luo Feng naturally understood many secrets!

“Familiarize yourself with the City Building Seal and quickly set up your own formations!” Lord Yuanxiang urged!

“I’m already setting them up!”

Luo Feng was currently in the state of consuming the Hundred Tribulations Heart Marrow, and his mind was in excellent condition even with a slight distraction. After Luo Feng refined the City Building Seal, one thought of his merged perfectly with the entire Rain Ripple City! Rain Ripple City was like a fortress-like secret treasure. Within this secret treasure were various complex secret patterns, and it carried a variety of powerful formation diagrams. However, these formation diagrams were too complex, and it was extremely difficult to comprehend and control them!

For example, the Star Cluster Formation Diagram was one of the few formation diagrams that the Elders of Rain Ripple City could control!

“Buzz!”

Rain Ripple City naturally absorbed the endless power of heaven and earth, and the energy of Rain Ripple City was vast and boundless, also supplying countless cultivators within the city to absorb!

As the City Lord, Luo Feng could mobilize one-tenth of the city’s energy for his own use, but this required a high level of realm and placed a great burden on the mind!

If it was the Palace Lord, they could only mobilize two-thousandths of the city’s energy at most!

If it was an Elder, they could mobilize one ten-thousandth of the city’s energy at most!

No wonder each Elder in Rain Ripple City managed a defensive system. The hundreds of defensive systems were perfectly coordinated. Luo Feng discovered this when setting up the formations!

The core formation diagram of Rain Ripple City had a thousand blank layers, and each blank layer did not interfere with each other!

The City Lord, Palace Lord, and Elders each chose only one “blank layer” to set up formations as they pleased, without needing any materials. As long as the formation was engraved, Rain Ripple City could perfectly exert the formation’s power!

“Because it is set up by themselves, each Elder can perfectly and easily drive the formation.” Luo Feng was also setting up quickly!

His accumulation in the Dao of Creation and Destruction, Life, and Destruction was already extremely deep. The Dao of Creation and Destruction was even close to the late stage of God Emperor. With such a profound accumulation, the formation that Luo Feng set up was naturally extremely vast and powerful!

The Palace Lord and Elders of the entire Rain Ripple City had set up hundreds of formations, among which Lord Yuanxiang’s formations were the absolute best!

“Now the formations are even stronger!” Luo Feng refined the City Building Seal, and as the City Lord, he could naturally see every layer of the formations!

Lord Yuanxiang was, after all, an Enlightened One who had mastered two and a half Chaotic Source-level Daos.

The formations he set up far surpassed those of Palace Lord Weiyang and Palace Lord Gai!

However, Lord Yuanxiang could no longer exert the full power of the formations!

Such a large formation would require Lord Yuanxiang to expend at least 10-20% of his mind to drive it!

But the current Lord Yuanxiang could only exert a small amount of his own formations’ power, and he had no advantage compared to Palace Lord Weiyang and Palace Lord Gai! Even among the God Emperors in the city, Palace Lord Weiyang was ranked first!

“My corruption has reached its limit. Those leader-level mind-related low-level Chaotic Source Lifeforms would probably be able to sense the terrifying corruption I am suffering just by looking at me!” Lord Yuanxiang sighed!

Now, every moment was as if he were a drowning man, seemingly about to drown at any time. He was struggling to support himself, and Palace Lord Weiyang was ready to obtain the City Builder’s authority!

His weakness also attracted the attention of the newly born Transcendent-level Mind-Bewildering Worm, which felt that Rain Ripple City was the easiest city to break through!

“The hundreds of millions of cultivators in Rain Ripple City, I have chosen Luo Feng as your City Lord. He is rising rapidly, and he is much more suitable than me!” Lord Yuanxiang vaguely saw the image of a golden-scaled woman. That high-level Chaotic Source Lifeform had broken through in front of him, and her corruption was deepening into every part of his mind!

“The gap with high-level Chaotic Source Lifeforms is too great!” Lord Yuanxiang sighed silently!

God Emperors and high-level Chaotic Source Lifeforms were two different levels of life!

No matter how many God Emperors there were, be it a hundred million, a billion, or a trillion… they would all be crushed with one foot in front of a high-level Chaotic Source Lifeform!

Of course, there were also some imprisoned high-level Chaotic Source Lifeforms in the Dark Sacred Realm that could not exert their strength or transmit any corruption, but were allowed to be observed, studied, and even dissected by cultivators!

But if they were not imprisoned or restrained and could normally exert their strength, then those high-level Chaotic Source Lifeforms were the nightmare of every God Emperor! “Hmm?”

Lord Yuanxiang suddenly changed his expression. Now that he had given the City Building Seal to Luo Feng, his own authority had been reduced, but he had left a contingency plan. His clone still had the “Palace Lord” authority. He would wait until the end of this war before completely leaving!

With the Palace Lord’s authority and the formations he controlled, Lord Yuanxiang still understood everything inside and outside the city!

“Another legion of low-level Chaotic Source Lifeforms is coming!” Lord Yuanxiang could see! A vast legion arrived outside the south gate!

Rumble! The arrival of the new legion and various joint attacks significantly increased the pressure on the entire Rain Ripple City!

“Yuanyan, you’ve come!”

Among the legions of low-level Chaotic Source Lifeforms that surrounded Rain Ripple City on all sides, there were also three terrifying auras!

These terrifying auras were all watching the newly arrived existence from afar!

“Knowing that the operation was launched ahead of schedule, I led my subordinates to travel with all our might, and finally arrived!”

A black mantis-like figure resembled a mountain range. This figure contained endless heat, and flames were rising on its surface. However, it would probably take a while for the other Kings to arrive!

“This launch was very hasty, but Ying led his Mind-Bewildering Worms and Soul-Eating Clan to fully attack and kill the Elders in the city. Rain Ripple City’s resistance is slowly decreasing. If this continues, I believe we will be able to break through the city soon!” “It’s been a long time since we broke through a city!” The mantis mountain range figure looked at Rain Ripple City with scorching eyes!

The four Kings and a large number of low-level Chaotic Source Lifeforms outside the city were all filled with murderous intent. They all longed for the moment when they broke through the city! At that time, they could slaughter the cultivators to their heart’s content in order to evolve and gain freedom!

“There’s one more legion, one more King!” Lord Yuanxiang frowned. “The pressure is too great! And the Elders in the city are being killed one by one. So far, we have lost 35 Elders!”

“The Elders are constantly decreasing, and the attacks from outside the city are getting stronger and stronger!” Lord Yuanxiang looked at Luo Feng beside him!

“Even with Luo Feng joining in, we won’t be able to hold on for too long!”

The new legion required dozens of Elders’ formations to resist, completely offsetting the help that Luo Feng had brought!

“Although the Elders in the city and some other Elder-level powerhouses have formed teams to intercept and kill the lurkers, they are only slowing down the deterioration of the situation!”

“I estimate we won’t last for half a day!”

Lord Yuanxiang was very anxious!

He had tried everything he could, but according to his judgment, Rain Ripple City would probably be breached.

At this moment, while setting up the formations, Luo Feng also sensed the situation inside and outside the city. The situation was getting worse and worse, and he was also anxious!

“It’s done!”

Finally, Luo Feng completely engraved a complex Great Formation of Creation and Destruction into the core formation layer of Rain Ripple City!
