After Xu Yu got the medicine from Qiao Bailin, he directly handed it over to the R&D institution and began to do an investigation and make an antidote.

It was not until half a month later that the antidote was initially successful, although it could not be directly controlled by the drug, but it could make the patient sober up, as long as he took the drug on time, he would not be controlled.

Xu promised to get the news, although he couldn't contact the medicine on Zhang Sibai's body for the time being, but it was already very good to be able to control it.

When this matter is dealt with, she will help Zhang Sibai to seek medical treatment again, and I believe that there will definitely be a better solution here.

After Xu Promise got the medicine, he returned home and saw Xu's father.

"Uncle, I've got the medicine, I want to go back to City C."

Seeing this, Dad Xu couldn't help but ask.

If he promised to go to City C alone, he was still a little uneasy.

So Dad Xu thought for a while and said.

"I don't think it's better to do this, I'll go to City C with you, otherwise I'm really a little at ease alone."

Xu Yu looked at Xu's father, then glanced at the children beside him, and fell into a tangle.

Although it is good to go back to C City together, at least there will be someone around to take care of it, but there is another problem, they go back together, four people, the goal is really a bit big, it is not a good thing for them, she thinks it is better to keep a low profile.

"Uncle, I've thought about this too, I still think it's okay for me to go back alone, it's better for you to take the child in country M."

Dad Xu is still a little worried, this matter has developed like this, although it is good for her to go alone, but there are also bad points, since those people dare to scare Zhang is medicine, then it shows that they will not treat Xu Promise in a frenzy.

So Dad Xu is still quite worried.

Now that things have developed like this, Xu Promise doesn't know what to say, things have developed like this, the best way is to deal with it, otherwise in the end, she is also worried that Chrissy's life will be difficult, after all, without backing, nothing can be done.

Xu Yu thought about it for a while, but still looked at Xu's father and said.

"Uncle, I've already thought about it, you better stay in City C and take care of the children for me, this time I will definitely be in danger of going to City C, I can't let the children have an accident?"

Father Xu didn't know what to do, and he really wanted to go with the promise, not only because of the promise, but also because of Chriss.

This time, he promised that if there was danger in the district, he could also protect Chrissy, although his own ability was insufficient, but it was better than doing nothing.

Xu Promise looked at the faint arc in front of her, and her heart was very entangled, what her uncle meant, she knew very well, in fact, things had come to this point, and she didn't want him to take risks, so ......

"Uncle, I know what you mean, you are also worried about me, worried about Chrissy, after all, we are the last relatives in the world, but I don't want that matter to develop to this point, the people I am most worried about are the children, so I entrust the children to you now, I hope you can take care of them."

Dad Xu didn't know what to say, he knew very well what he meant, and he didn't want such a thing to happen, and the reason why idle things were like this was a last resort.

But I still can't rest assured.
