Shen Muzhi hung up the phone, went into the bedroom to get a coat, and said to Xiang Zhilan, "Tell Ni Sitian not to worry, I will find Tingchuan."

"Okay." Xiang Zhilan followed behind him, intending to see him downstairs.

Shen Muzhi stopped at the top of the stairs and said to Xiang Zhilan, "You're not feeling well, so don't climb up and down the stairs. Go and rest. We'll contact you by phone if anything comes up."

Xiang Zhilan stopped in front of him, nodded, and watched him go down the stairs. She couldn't help but call out, "Mu Zhi."

This was the first time he had heard her call his name like that. If it weren't for the urgency of the situation, he would have definitely run back upstairs to hug her. Now, he could only turn around and look at her.

"Be careful yourself too," Xiang Zhilan said with some concern.

"Mm." Shen Muzhi nodded seriously, glanced at her with a gentle look, and then turned and strode out.

After getting into the car, Ah Feng called again, saying, "Su Yan's car is at Qinghua Mountain. Ah Yu and I have arrived. Mr. Xu's car is also parked at the foot of the mountain."

"You guys go up the mountain quickly and look for him." Shen Muzhi thought for a moment, the reason why Xu Tingchuan came here so late was probably because of Ni Sitian's antidote knot.

Qinghua Mountain, Qinghua Mountain...

He suddenly remembered something and quickly said, "Go to the top of the mountain, to Li Jing's grave in the third row of the cemetery!"

"Yes." After receiving the instructions, Ah Feng and the others immediately took out flashlights from the trunk of the car and ran towards the top of the mountain as instructed.

Shen Muzhi frowned, and the more he thought about it, the more he realized that this was the case. Xu Tingchuan and Su Yan went to Qinghua Mountain late at night, so they must have only one purpose.

"Ah Chao, drive faster!" Shen Muzhi urged.

Su Yan is capable of killing even Li Rui when she goes crazy. It's dark and dangerous on this mountain, so Xu Tingchuan is likely to be at a disadvantage. And now that we haven't been able to contact her for so long, it's really worrying.

By the time Shen Muzhi arrived at Qinghua Mountain, it was already one o'clock in the morning, the darkest and most intense time of night.

Looking up at the mountain, there was a gloomy and eerie atmosphere.

"You stay here and keep watch." Seeing that Su Yan's BMW hadn't been driven away yet, Shen Muzhi figured she must still be on the mountain, but she would come down sooner or later, so he told A-Chao to wait for her at the foot of the mountain while he went up the mountain himself.

Halfway up the mountain, I received a call from Ah Feng, who sounded very anxious: "Sir, we found Mr. Xu's flashlight and cell phone on the cliff behind the mountain."

The reason we were able to tell that the phone belonged to Xu Tingchuan was because his screen saver was a photo of Ni Sitian.

Shen Muzhi's heart skipped a beat, and he ran quickly towards the top of the mountain.

About fifteen minutes later, he arrived at the back of the mountain and immediately ran over to Ah Feng and the others.

“Sir, we’ve already checked. There are two smaller footprints that have retreated to the edge of the cliff, and there are also marks of sliding down. Mr. Xu’s footprints are here. This patch of grass has been trampled. It seems that Su Yan was about to fall, and Mr. Xu pulled her up.” A-Feng reported to Shen Muzhi, “I judge that Mr. Xu may have been pulled down.”

Shen Muzhi's expression changed slightly. He squatted down and shone his flashlight at the cliff face, but unfortunately, he couldn't see the bottom at all.

Few people come to the back of Qinghua Mountain, and they have no idea how deep the ravine is.

"Is there any other way down?" Shen Muzhi thought it best to go down to the bottom and find out what was going on.

"No, and the cliffs here are very slippery and covered in moss. We can't get down there at all," Ah Feng said in a deep voice.

Shen Muzhi took out his phone, made a call, and after hanging up, he walked around the neighborhood and searched for more information.
