"Sister, where are you now, this number looks very raw?" Xiao Yuan suddenly received a call from Tang Sa, he was very surprised, but the caller number was very unfamiliar, he wanted to know where Tang Sa was at this time, so he asked.

"I'm in Brazil, and I want you to do my sister a favor." Tang Sa said.

"Sister's business is my business, what do you say to help?" Xiao Yuan said.

"Well, my sister loves to hear what you say, come, kiss one, mua~" Tang Sa smiled on the other end of the phone and kissed Xiao Yuan in the air.

"What the hell is going on?" Xiao Yuan asked.

"Help my sister find an expert in image recognition at Berkeley, and my sister needs his help with something." Tang Sa said.

"Image recognition expert?" Xiao Yuan was a little surprised.

"Yes, image recognition expert, sister needs an expert in this area now." Tang Sa said.

"Sister, I don't think you need to go to anyone else." Xiao Yuan said with a smile.

"Why don't you go to someone else, don't you still understand image recognition technology?" Tang Sa heard the meaning of Xiao Yuan's words and asked in surprise.

"Bingo, you're right, I know a little bit about image recognition technology, and if you're willing to believe me, I'm willing to help you." Xiao Yuan said.

"Image recognition is not network technology, what my sister has to do is very important, do you really understand image recognition technology?" Tang Sa half-believed, no wonder she, although image recognition and network technology belong to the same category of computer technology, but these two technologies are very different, theoretically speaking, image recognition technology involves computer graphics, mathematics, and artificial intelligence and many other disciplines, computer students are generally only involved in graduate school, if you want to study in depth, you generally have to get a doctorate, so, Tang Sa heard Xiao Yuan say that he understands image recognition technology, although she knows that Xiao Yuan will not lie to her, But I still subconsciously had doubts.

"You know, by the way, sister, what are you going to do with image recognition technology, do you want to find someone?" Xiao Yuan asked.

"I'll leave for the United States right away, and I'll talk about it when we meet, it's inconvenient on the phone." Tang Sa said.

"Okay, it's great that you're back, I've been worried about you since you're gone." Xiao Yuan was overjoyed when he heard this.

"That's it, you go get busy, I'll contact you when I get back, hang up first." Tang Sa said, and after speaking, he was reluctant to give up and hung up the phone.

After hanging up the phone, Tang Sa waited in the room for almost an hour, Jiang Hua walked in from outside with a piece of sketch paper, and handed the sketch paper to her, Tang Sa looked at it, and a white man was drawn on the sketch paper, with a long face and a big beard, looking a bit like a Middle Easterner.

"This is a sketch of Carl drawn according to Gao Huaiyingde's narration, and according to his confession, the similarity is not less than eighty." Jiang Hua said.

"Okay, I see, you can arrange for someone to go to the airport to buy me a ticket to Berkeley now, the sooner the better." Tang Sa put away the sketch paper, gave his ID to the speech, and commanded.

"You're going to Berkeley?" Jiang Hua asked with some surprise.

"Yes, I'll go to Berkeley to find Xiao Yuan and ask him to help me do something." Tang Sa smiled and said.

"Okay, I'll arrange it now." Jiang Hua withdrew from the room again, but this time he came back quickly, and when he came, he also handed a bag to Tang Sa in his hand.

"What is this?" Tang Sa asked.

"I'll prepare some gifts for Xiao Yuan." Jiang Hua said.

Tang Sa opened the bag, picked out a box from it, and there were two green fruits in it, exuding an attractive fragrance, and asked curiously, "What is this?" ”

"The fruit of the Kara tribe's specialty, let Xiao Yuan eat it, it is very good for him." Jiang Hua said with a smile.

"What's in it for you?" Tang Sa continued to ask.

"Hehe, in short, it's good, are you still afraid that I will hurt him?" Jiang Hua laughed twice, but he was unwilling to say what the effect was.

"Forget it, if you don't want to say it, don't say it, I'll hand it over to him when the time comes." Tang Sa saw that Jiang Hua was reluctant to say more, so he didn't continue to ask, but closed the box, put them in the bag, and put the bag into his suitcase.

"By the way, after I'm gone, you must be careful of Old York." Tang Sa said again.

"Don't worry, he can't do anything to us, you must know that our forces are not weaker than him, even if he finally guesses that we stole Gao Huaiying, he will never dare to act rashly, in this area, there are at least three forces eyeing him, and it will not do him any good if he gets into trouble with us." Jiang Hua waved his hand and said.

Tang Sa knows Jiang Hua's adaptability very well, plus he is protected by a hundred experienced female warriors around him, there should be no problem with safety, even if Old York is a local snake, Jiang Hua can't fight as an outsider, no one can stop him from escaping, the most important point is that Jiang Hua is the king of the Kara tribe, and the warriors of the Kara tribe are famous in the mercenary world, this alone is enough to make the old York jealous and dare not act rashly.

"If it's possible, find a way to have a good relationship with Old York, maybe in the future, when dealing with target A, he will be very helpful to us, Gao Huaiying's value is gone, and we can use it when necessary." Tang Sa commanded again.

"Won't Gao Huaiying be sent back to China for trial?" Jiang Hua listened to Tang Sa's words and asked with some surprise.

"The general is outside, the king's order is not affected, Gao Huaiying's defection has been completely investigated, and escorting him back to China is more symbolic than practical, do you understand what I mean?" Tang Sa said with a slight smile.

"I see." Jiang Hua nodded.

"Okay, I'm sure you can handle it, in addition, don't forget the fundamental purpose of your coming here, Gao Huaiying is just a small thing to do, the real big thing is to investigate Target A, and another point, Target A is likely to know about your existence, so, you have to be careful about doing things in the near future, there is another thing I have always thought is strange, why did Target A send Gao Huaiying to South America, and it was so coincidental that he was sent under your nose." Tang Sa said again.

"Do you suspect that the reason why Gao Huaiying was sent here was completely deliberate by Target A?" Jiang Hua frowned and asked.

"Yes, I've always had that suspicion." Tang Sa said.

"What is he doing this for?" Jiang Hua asked.

"I don't know, so, you have to be more careful, what you have to do at this stage is to keep your eyes on the dark and slowly accumulate strength, as for the investigation, you don't have to deliberately, the organization didn't give us a time limit, so why should we rush for a while?" Tang Sa said.

"I see." Jiang Hua was thoughtful.

"Okay, I've always believed that you can handle these things, you go, I'll rest for a while, and when the ticket is bought, come and call me again." Tang Sa waved his hand and let Jiang Hua leave the room, and he leaned back on the rocking chair again, closed his eyes and recuperated, and after a while, the corners of his mouth tapped upwards and muttered, "Little enemy, how many secrets do you still have that my sister doesn't know, you will also know image recognition technology, my sister is very curious, where did you learn these things?" ”
