Just as Bai Luochu felt that her spiritual energy couldn't resist the pressure coming from Pei Qingfeng and was about to collapse, she finally found the source of the sickness deep inside his meridians.

Inside his body! How could there be something so sinister hidden deep in his body?!

Bai Luochu might be an evil dao witch in her previous life. However, as for those extremely vicious and sinister things in the world, she only read about them in the temple's library. Those orthodox sects who flaunted themselves as righteous would never use such methods to harm people. Even the disciples of the temple who were known as evil dao practitioners wouldn't commit such outrageous acts.

Seeing the change in Bai Luochu's expression, Pei Qingfeng was startled and felt extreme astonishment in his heart. Did she see something?! In the entire Cloud Water Nation, the number of individuals who could see the root of the problem could probably be counted on one hand.

Right at this moment, Bai Luochu said something and confirmed Pei Qingfeng's suspicion.

"Can you tell me, how did this thing..."

"You saw it?" Pei Qingfeng spoke indifferently. It was as though he wasn't the one who was sick.

"I didn't think you could actually see it. You are truly extraordinary. This thing has been inside my body for a very long time... so long that I have already forgotten about it." Pei Qingfeng still had that indifferent look plastered on his face. After staying silent for a moment, he chuckled, "Can you cure me?"

Even though Pei Qingfeng was inquiring about treatment, it was clear from his tone and expression that he wasn't optimistic about her reply.

Bai Luochu knitted her brows and didn't reply. If the thing inside Pei Qingfeng's body was some sort of illness, it would be much easier for her to cure him. Too bad it was far from an illness. It was an extremely vicious and sinister poison array.

A moment ago, just as Bai Luochu was about to give up, she noticed some extremely strange runes in his body.

In the beginning, Bai Luochu didn't understand the meaning of the runes. As she continued to observe the runes, purple thunder burst out from them. When the purple thunder emerged, it made a complete cycle around the meridians before returning. An astounding amount of spirit qi was absorbed from Pei Qingfeng's body.

When the purple thunder appeared, Bai Luochu felt that it was a familiar scene. However, she wasn't able to make the connection and only after the purple thunder returned to the runes did the memory deep in Bai Luochu's mind resurface.

Poison Fire Heaven Thunder Array!

Bai Luochu had seen such an array in her previous life and it was when she was browsing the library in the temple. Due to the viciousness of the array, it was labelled as a forbidden array by the Patriarch. Once, there was someone who tried to secretly learn the poison array but his actions were discovered. His cultivation was crippled and he was driven out of the temple.

The only ones who could access this array were the Patriarch and the inner temple disciples. Furthermore, they weren't given access to the poison array itself but the neutralization method instead. It was their contingency plan in case any disciple secretly learned the array to bring harm to people. If such a thing really happened and no one in the temple could neutralize it, they would be sinners.

The array was vicious as it wasn't a simply poison array. Normal poison arrays would be created by various poison herbs and plants. The worst of the regular poison arrays would only cause the victim to be inflicted with a poison curable by any good physicians.

As for this array, it was a different case altogether. The Heavenly Thunder was imbued into the runes and were sealed and concealed inside the meridians. When the victim's cultivation was below a certain level, the thunder running through the meridians would be mild and the pain the individual suffered wouldn't be excruciating. The spirit qi the Heavenly Thunder absorbed wouldn't be too exaggerated. It would cause the victim to think that it was the side effects of their rapidly increasing cultivation.

When the victim of this poison array reached a certain cultivation realm, the thunder would become extremely strong and it would absorb more spirit qi from the victim's body. By the time the cultivator noticed that something was wrong, it would already be too late. The poison array would already have taken root in their body.

There was something even more shocking in the book about the effects of the array.

Apart from releasing thunder to absorb the host's spirit qi, the runes were also a kind of spatial access allowing the thunder to bring the spirit qi to the caster.

Bai Luochu didn't know what to say for a moment. What should she say? Should she say that his body had an extremely vicious poison array and if he wanted to neutralize it, it would take a very long time? Or should she say that the poison array inside his body was probably inflicted by someone close to him, bringing the sickly prince even more frustration and sorrow?

The true question was Pei Qingfeng's understanding of the array.

Without thinking too much about it, Bai Luochu blatantly asked, "What do you understand about the poison array in your body?"

"I know enough. Can you treat it?" Pei Qingfeng smiled and didn't seem to be in a hurry at all.

Looking at Pei Qingfeng's appearance, Bai Luochu's respect for the man grew to the next level. His wisdom was truly extraordinary.
