"Xue'er, are you in front?" Xu Mengling couldn't help but shout after walking into the small courtyard.

Zheng Xue'er, who was meditating in the room, suddenly heard Xu Mengling's voice and couldn't help but be stunned.

"Why are you here?" asked Zheng Xue'er hurriedly ran to the window.

"Didn't you ask someone to throw a note asking for help, how could you be locked up?" Xu Mengling said in a low voice.

"It's a long story, and I need you to do me a favor. Zheng Xue'er couldn't help but be stunned when she heard the two words of the note, she was smart and icing, and she immediately understood that it was Zhang Yu's idea, and she also heard the personal maid who delivered the meal say that Zhang Yu asked to see her at the door several times, but she didn't get her father's consent.

"What do you want me to do?" Xu Mengling nodded hurriedly.

"First of all, I don't have a special relationship with Zhang Yu!" she looked at Xu Mengling and said very solemnly, Xu Mengling heard Zheng Xue'er's words, looked at her cautious expression, and couldn't help but be overjoyed.

"The patriarch took a fancy to Zhang Yu's ability and wanted to keep him in the Heavenly Medicine Valley and let me marry him......" Zheng Xue'er continued, her father had hinted at it a few times, and she understood what was going on as soon as she heard it.

"What?" Hearing this, Xu Mengling and Lin Xueyue were taken aback at the same time, Lin Xueyue hurriedly told Zhang Yu what Zheng Xue'er said, Zhang Yu never dreamed that things would be like this.

"Can you help me?" Zheng Xue'er stared at Xu Mengling with big eyes.

"I ...... How can I help you?" Xu Mengling thought for a moment and said, he didn't want Zhang Yu to stay here, so he understood what Zheng Xue'er meant.

"Do you remember that adventure we had when we were children?" Zheng Xue'er did not answer, but said this.

"That adventure, you mean the valley of death......" Xu Mengling said in surprise. He still remembered that the two of them were only in their teens at the time, and they were in a rebellious period, and they heard many adults say that the valley of death was particularly terrifying, they just didn't believe it, Xu Mengling was pulled by Zheng Xue'er to explore.

They encountered a terrifying python, and at the moment of crisis, two strange people saved them, and finally found a passage to the outside world, and finally Xu Mengling was afraid of being beaten and scolded by adults, and the two returned to the Heavenly Medicine Valley after suffering.

When he came back, he was beaten and scolded, and he was confined for a few days.

But in the Valley of Death, there is a passage to leave the Valley of Heavenly Medicine, which is the secret of the two of them.

"Yes, can you take Zhang Yu away? Also, I promised him to help him test his grandfather's blood, and he is still in the testing workshop, and I also hope that you will hand him over to Zhang Yu." Zheng Xue'er's bright eyes looked at Xu Mengling.

"This ......" Xu Mengling hesitated for a moment, he raised his head and looked at Zheng Xue'er with an expectant face, and suddenly remembered the expectant look in her eyes when she asked him to accompany her to the valley of death when he was a child.

"Okay, I'll go!" Perhaps knowing what kind of punishment he would receive, he did not hesitate.

"Thank you!" Zheng Xue'er was silent, she could feel Xu Mengling's good impression of her, which moved her, maybe, maybe one day, she could accept him.

"Then I'll go get the report......" Xu Mengling said, then he heard Ah Fu calling him outside, and then he turned around and left.

"Brother Xu, if this incident passes, can you come to 703 to help me?" Suddenly, Zheng Xue'er shouted loudly.

"Okay!" Xu Mengling's eyes flashed with excitement, he exhaled deeply, nodded, and strode out.

In the small bamboo building, Zhang Yu got Lin Xueyue's feedback, and couldn't help sighing, he couldn't imagine that his talent would be used by others, and after thinking about it, the only way to do this is to listen to Zheng Xue'er's method and take a trip to the deep valley.

Zhang Yu asked in detail about the situation in the deep valley, she didn't encounter the giant python, but the two weirdos were particularly powerful.

There is no way now, unless he forcibly breaks into the Heavenly Medicine Valley, which is simply unrealistic.

After Xu Mengling left the Zheng family, he did not go back, but went to get the report.

"But Elder Chen told us that this report cannot be handed over to anyone. Zhang Qiang, the staff member inside, said with a frown.

"Can't even me?" Xu Mengling asked angrily.

"This ...... Of course. Zhang Qiang was very entangled, and in the end he handed over the report to Xu Mengling, after all, Xu Mengling was still very prestigious in the Heavenly Medicine Valley, and no one dared to offend him.

"What's wrong with this report?" Xu Mengling looked at the report and asked curiously.

"The sample blood was found to be very special toxicity, which has not appeared in China, and is more used in Western Europe, called burning heart, and there is no antidote formula in Tianyi Valley at present. Zhang Qiang said.

"What are the symptoms?" said Xu Mengling, looking at the report card.

"This poison also belongs to the type of blood sealing the throat, unless there is a very deep cultivation, the toxicity can be suppressed, but it cannot expel the toxin, and the toxicity will slowly manifest over time. ”

"And how long do you think this man will last?"

"For months, or days, it's uncertain. Zhang Qiang shook his head and said.

"Okay, thank you!" Xu Mengling nodded in thanks and turned to leave.

As soon as Xu Mengling left, about half an hour later, Elder Chen appeared in the inspection workshop for a routine inspection, and Zhang Qiang reported the matter of Xu Mengling taking the report to Elder Chen.

"Why did you give him the report, didn't I explain it to you?" Elder Chen asked with a frown.

"This ......," Zhang Qiang was speechless.

"Okay, I know about this matter, you go and get busy!" Elder Chen also knew that Zhang Qiang couldn't refuse, nodded and said, Zhang Qiang was released, and hurriedly left to get busy.

"Why did he take away the report?" Elder Chen was puzzled, could it be that Xu Mengling wanted to take revenge on Zhang Yu?

"A few of you go to see if Xu Mengling is going to find Zhang Yu. Elder Chen said to his subordinates, and his subordinates nodded and hurried away.

After a while, they came back here and reported, "Young Master Xu didn't go to find Zhang Yu, but went back. ”

"Oh, I see!" Elder Chen vaguely felt that something was wrong there, he thought about it, thought that he was too sensitive, and turned around and led his men to continue to inspect.

Xu Mengling didn't go directly to Zhang Yu with the report, but went back, because he knew that Zhang Qiang would definitely report to the top.

After he came back, he specially called someone to monitor the door, and sure enough, he saw the person who was following him, and after the person left the tracker, he waited until the evening before quietly leaving through the back door wearing a cloak.

After thinking about it for a long time at home, Zhang Yu still decided to talk to Zheng Xue'er, even if he had to go through the valley of death, the situation in it was not clear at all, and it was easy to suffer a big loss.

When it was dark, he quietly used the invisibility charm and left the small building.

After about half an hour, he came to the Zheng family, probably in the Heavenly Medicine Valley, plus two ninth-level Qi refining masters. The Zheng family came out of the open and dark sentinels, and did not set up a ban, so Zhang Yu's secret infiltration did not attract anyone's attention.

At this time, Zheng Xue'er had just fallen asleep, she suddenly heard someone calling her, and she opened her eyes to see a figure standing outside.

"Who are you?" asked Zheng Xue'er vigilantly.

"I'm Zhang Yu!" Zhang Yu looked around and whispered.

"Zhang Yu, are you here? You know the matter, right?" Zheng Xue'er hurriedly got up and walked to the door and asked.

"Well, guess a little, you are locked inside?" Zhang Yu stretched out his hand to open the door, but was stopped by Zheng Xue'er.

"There is a ban on the door, you can't open it, you have to leave immediately...... now" Zheng Xue'er lowered her voice and quickly said what she guessed, although Zhang Yu had heard Lin Xueyue talk about it, but when he heard Zheng Xue'er say it in such detail, he still felt incredible.
