Qin Wentian stared at Pei Qing as he spoke in a domineering manner. He wasn't willing to create multiple powerful enemies but it's tough to avoid conflict with some characters. Back then, the first time was when he was in the forbidden ground, and the second time was now. If he continued to endure it, there was only a single path remaining for him. When Pei Qing told him to scram earlier, he would have already done so, slipping away with his tail between his legs.
But clearly, this didn't fit his personality. Hence, he could only offend Pei Qing. Since it was already fated that he would offend Pei Qing, there was no need for him to worry too much. This was the same with Beiming Youhuang. When Beiming Youhuang wanted to seize his memories then, he used all methods at his disposal to prevent it. Unless he was willing to hand over his memories obediently, if not, he could only struggle with everything he had to resist.
