The simple phrase "they have been irreconcilable since ancient times" is enough to explain this.

Therefore, when Lin Xiuyuan discovered its true form, he guessed that it might be a spy sent by the demon race to infiltrate the human race. In the past, demon race spies had repeatedly stirred up trouble and caused great casualties to the human race, so he immediately had the intention to kill it.

However, the fire talisman master was willing to acknowledge a master on the spot, but it was still a master-servant brand. Seeing this, Lin Xiuyuan thought about it and, considering a trace of affection, decided to wait until things settled down before making any further plans.

The fire python coiled and writhed, gradually transforming into a snow-white, graceful, and flawless jade body, completely naked.

Lin Xiuyuan watched her calmly as she took out her clothes and put them on. After she finished, he spoke:

"What is your purpose in infiltrating the human race this time? And in Nanzhou, is there anyone to help you? Back in Beihe Market, someone must have helped you escape, right?"

The Fire Talisman Master looked at Lin Xiuyuan with a complex expression in his eyes. After a moment, he regained his composure and slowly shook his head, saying, "I am not a spy."

Upon hearing this, Lin Xiuyuan was slightly taken aback, his eyes filled with disbelief, yet he had no choice but to believe it.

Because of the mark of recognition, although it cannot fully understand the thoughts of the fire talisman master, it can still clearly perceive the truth or falsehood of their words.

Is it true? Or is there another way to cover it up?

Lin Xiuyuan felt that the latter was more likely. If the other party was a spy from the demon race, how could they not have some means of concealment to avoid the immortal sect's methods, such as the Heart-Questioning Array?

Immediately, a cold glint flashed in Lin Xiuyuan's eyes, and he activated the branding restriction without hesitation.

Immediately, a sound of extreme pain came from the Fire Talisman Master's mouth.

"Ah ah..."

The Fire Talisman Master opened his mouth, wanting to say something, but immense pain engulfed him, as if spreading from the depths of his heart and soul, swallowing him up like a tidal wave. He was unable to form any thoughts, let alone utter a single complete word, and could only wail incessantly.

In an instant, her face was filled with pain, a pain that came from the depths of her soul, causing her to endure unimaginable agony. She curled up on the ground, convulsing and rolling around.

It could barely maintain its human form and directly revealed its fiery python body. Rapid hissing sounds rang out as its entire body twisted and writhed, its tail lashing the ground in an attempt to relieve the pain, causing the stone bricks on the ground to crack and create small pits and fissures.
