Wu Wei clenched his fists, silently looking at the corpse of his youngest son, split in half on the ground.
He had already understood the hidden meaning in Liu Yihe's words—wasn't he just trying to seize this opportunity to extort a huge benefit?
Moreover, he had long known what Liu Yihe needed, he just hadn't been willing to give it.
However, now that his youngest son had been killed, he was willing to pay any price to find the murderer.
Thinking of this, Wu Wei spoke.
"Brother Liu, I heard you have a grandson with a sixth-grade Fire Spiritual Root. You've always wanted to find a suitable Fire Cultivation Technique for him. This time, as long as you help me find the murderer who killed Tianyi, I can make the decision to give the Wu family family's Blazing Heart Incantation to your grandson to Cultivate."
"Is that true?"
Hearing this, Liu Yihe couldn't help but excitedly confirm.
The Blazing Heart Incantation is a Low Grade Profound Rank fire-attribute Cultivation Technique, and also the protective Cultivation Technique of the Wu family family in Feiyun City.
Not to mention an outsider, even ordinary Wu family family Disciples were not qualified to Cultivate it.
Although Liu Yihe served as a Protector in the Wu family family, he was not a solitary individual; he also had family and relatives.
Among them, a six-year-old grandson had earlier been found to possess a sixth-grade Fire Spiritual Root.
Since then, he had always wanted to find a suitable fire-attribute Cultivation Technique for his grandson.
The Wu family family's Blazing Heart Incantation, as a Profound Rank Cultivation Technique that directly leads to the Nascent Soul Dao, was clearly very suitable.
He had previously hinted to Wu Wei about this matter, but he had always been brushed off and evaded.
No matter how great a price he was willing to pay, Wu Wei had no intention of passing on the Blazing Heart Incantation to an outsider.
If it weren't for Wu Tianyi's sudden death this time, Wu Wei would definitely not have relented.
"Naturally, it's true, but your grandson will need to sign a contract with the Wu family family."
"No problem."
Signing a contract was normal, and Liu Yihe didn't mind it. As long as his grandson achieved success in Cultivation, how could a mere contract restrain him?
Moreover, he could still live for several decades, at least long enough to help his grandson achieve Foundation Establishment.
As long as his grandson successfully achieved Foundation Establishment, the rest of the path would be up to him.
So Liu Yihe readily agreed.
After the two continued to discuss some specific details, Wu Wei cupped his hands and said.
"Brother Liu, I'm counting on you. You must find the murderer."
"Family Head, please rest assured. In two hours at most, I can track the murderer's whereabouts."
With his wish fulfilled, Liu Yihe was very happy, and even in his words, he showed more respect to Wu Wei.
As for whether he could find the murderer, he was not worried.
To be honest, although the murderer's actions were clean and decisive, and not many traces were left at the scene.
However, this murderer was clearly a novice. After killing, he neither destroyed the body nor performed any subsequent handling.
Although Wu Tianyi was dead, and he died unwillingly, the resentment before his death still lingered nearby. The murderer did not dispel this resentment before leaving.
Following this resentment, and then employing some special methods, he was confident he could find the murderer's whereabouts.
Taking someone's money naturally meant working hard, especially since the benefits had not yet been received.
Liu Yihe took out small flags from his Storage Ring and set them up around the area.
Then he took out a completely black Formation Plate and carefully placed it where Wu Tianyi had fallen.
Wu Wei, standing beside him, roughly understood some of it, and he couldn't help but exclaim in admiration.
"Ten Thousand Miles Soul Chasing Spell? Brother Liu truly has excellent methods, to actually know such an obscure Spell."
"A small trick, not worth mentioning. Next, I ask the Family Head to be my Protector. When casting the Ten Thousand Miles Soul Chasing Spell, I absolutely cannot be disturbed."
After Liu Yihe finished speaking, he sat cross-legged and formed hand seals.
"Brother Liu, please cast your Spell with confidence. With me here, no one will disturb you."
Wu Wei flew into the air, his Divine Sense spreading in all directions, monitoring every movement around him.
At this time, Zhang Yuhe was happily flying towards Cloud Central City, completely unaware that the Wu family family would soon be able to track his movements.
This was also very normal; there were countless strange methods in the Immortal Realm.
Not to mention that he was only a semi-illiterate Cultivator, even an old monster who had Cultivated for a thousand years wouldn't know everything.
As Zhang Yuhe flew, he occasionally took out his Jade Slip map to compare and check.
Time slowly passed, and Cloud Central City was not far away...
Liu Yihe sat cross-legged on the ground, with a pile of Spirit Stones beside him. As his fingers continuously formed hand seals, the Spirit Stones rapidly depleted, and his face also became increasingly pale.
Although the Ten Thousand Miles Soul Chasing Spell had miraculous tracking effects, its consumption was also very great.
With his Middle Stage Foundation Establishment Cultivation, forcefully activating this Spell was indeed a bit strenuous.
Moreover, activating the Ten Thousand Miles Soul Chasing Spell would cause him great harm, and he would likely need a long period of recovery afterward.
If it weren't for the Blazing Heart Incantation, he wouldn't be working so hard...
Suddenly, Liu Yihe spat out a mouthful of vital blood and shouted loudly.
"Soul Chase, quick..."
As soon as his voice fell, points of light slowly appeared, then gradually converged to form an image of a Cultivator flying on a Flying Sword.
And the person in the image was none other than Zhang Yuhe.
Seeing the murderer's trace appear, Wu Wei descended from the sky and asked with a frown.
"That's the direction of Cloud Central City."
"Yes."
Liu Yihe replied helplessly.
As a prefectural city, Cloud Central City had Disciples of the Dao Saint Sect stationed there. Once the murderer entered Cloud Central City, they would be unable to act.
The most crucial thing was that the murderer was very close to Cloud Central City at this time. Even if they were faster, there was no way they could intercept him before he entered the city.
Liu Yihe somewhat wanted to retreat. He didn't have the guts to act under the nose of a Dao Saint Sect Disciple.
However, while he wanted to retreat, Wu Wei did not. He was now solely focused on avenging his son.
Wu Wei waved his hand and said to Liu Yihe.
"Let's go, we're going to Cloud Central City."
"Family Head, do you intend to act within Cloud Central City?"
Hearing that Wu Wei still wanted to pursue, Liu Yihe couldn't help but ask in great surprise.
"Of course, I wouldn't dare to act within Cloud Central City. We just need to go there and keep a close eye on the murderer. I don't believe he won't leave the city."
Wu Wei made up his mind; he would guard Cloud Central City and didn't believe the murderer could stay inside the city forever.
They couldn't act inside the city, but there were no restrictions outside the city. As long as the murderer left the city, he could avenge his son.
However, he had to bring Liu Yihe along, as he wasn't skilled in tracking people and needed Liu Yihe's help.
Their Wu family family's Blazing Heart Incantation wasn't that easy to obtain; how could Liu Yihe not work hard?
"Alright then, I'll accompany the Family Head on this trip."
Since Wu Wei insisted, Liu Yihe had no objections. As long as they didn't act within Cloud Central City, going to take a look was fine.
Moreover, Wu Wei was right; the murderer likely didn't know he was being tracked, so it was indeed unlikely he would stay in the city forever.
The two released their Flying Swords and quickly flew towards Cloud Central City...
At this time, Zhang Yuhe had already flown out of the forest, and a massive city appeared before his eyes.
The city walls of the giant city were over a hundred meters high, stretching as far as the eye could see, its perimeter unknown.
"It's truly magnificent. It's hard to imagine how such a large city was built."
Looking at the giant city before him, he couldn't help but exclaim that the Cultivation civilization was indeed grand and magnificent.
Thinking of this, he couldn't help but be filled with anticipation for the future.
"Let's enter the city first."
Zhang Yuhe quickly flew towards the giant city, with Cultivators flying on Flying Swords passing by him from time to time, then landing several hundred meters outside the city.
In the Yu Fan Heaven World, large cities at the prefecture and state levels all had anti-flight formations. Unless one's strength reached a certain level, flying was prohibited.
To enter the city, one could only walk.
