The undercurrent between the two lasted only a few breaths. When the camera panned to them, they both "tacitly" concealed the sharpness in their eyes.

Nan Xian lightly withdrew her gaze, while Wei Zeling lowered her eyes and suppressed her sly smile. Her slender fingers gently swept across the pipa, and several melodious notes flowed out, drawing cheers from all sides.

Because of what Nan Xian had said earlier, Yu Lin was on edge. He kept a close eye on her movements, ready to protect her at any moment. As luck would have it, he witnessed the entire intense eye-to-eye battle between her and Wei Zeling.

Clever as he was, he immediately guessed what was going on.

Seeing that everyone's attention was focused on the three guest stars, he took the opportunity to slip over to Nan Xian's side and tentatively asked in a low voice, "Wasn't Wei Zeling always abroad? When did she return to China and even learn to play the pipa?"

Nan Xian's eyes flickered slightly. "Who knows?"

At this moment, she was also speculating about Wei Zeling's purpose. Before today, she only regarded Wei Zeling as an immature child, but now she had to overturn her guess and re-examine her—whether she had really misjudged her, or whether her acting skills were too superb and she had fooled everyone.

“I feel like she’s acting a bit strange. Should we be on guard?” Yu Lin asked.

“Of course.” Nan Xian glanced around at everyone present without making a sound. “Not just her, you need to pay attention to everyone we interact with.”

Yu Lin responded with a "yes" and then quietly slipped back to his seat.

After the six guests gathered and the greetings and introductions were completed, Village Chief Gu took the stage and led the villagers in welcoming everyone.

After the joyful singing and dancing ended, Village Chief Gu said, "In our Buxianxian Village, we have a tradition that whenever distinguished guests arrive, we serve them with rice wine that we brew ourselves, and we also have the oldest person in the village give them blessings, hoping to bring everyone the spirit of longevity and peace!"

As soon as he finished speaking, an elderly man with gray hair and a wrinkled face appeared in a wheelchair. Behind him, several young men carried a huge vat, all full of energy, shouting slogans.

Nan Xian stood in the crowd, discreetly observing the elderly man in the wheelchair, her first glance falling to his feet.

However, whether intentionally or not, the old man was very thin, while the villager pushing the wheelchair was tall and robust, and his position blocked the sunlight.

His body completely enveloped the old man, and only his shadow could be seen on the ground.

Nan Xian frowned and took a few steps forward.

She learned some methods for distinguishing between humans and non-humans from [.h], with observing shadows in sunlight being the most common.

Some non-human beings can transform into human forms, but their shadows cannot completely imitate them and will always reveal some flaws. For example, if a demon is cultivated by an animal, its shadow will suddenly reveal the shape of an ear or a tail. If a dark and negative being is reincarnated as a human, their shadow will be hazy and blurry, unable to maintain the outline of a human for a long time.

If conditions are limited and it is impossible to observe the shadow, then it is necessary to observe it up close. When a person with spiritual energy and who has awakened can concentrate, they can see the true appearance of non-human beings.

The old man had dark skin, sunken cheeks, and his eyes had lost most of their luster, becoming cloudy. He wore a simple, honest smile and greeted everyone with slight unease.

Nan Xian calmed her mind and breath, and a golden light rose from her dantian, transforming into two streams of light that flowed into her eyes.

She gradually saw extremely fine threads appearing on the top of the old man's head and around his limbs.
