Natasha Romanoff, who came out of the Hilton Hotel, was full of anger in her heart, even though she looked extremely beautiful and moving, but the cold breath had already frightened several men who wanted to come forward to say hello.

Sitting back in the car, Natasha couldn't help but slam the steering wheel twice, if it weren't for the car's steering wheel being custom-made, I'm afraid it would have been smashed by Natasha a long time ago.

In fact, when she saw the specialized nurse prepared in the next room, Natasha couldn't help frowning. Tonight's skin care, Ling Xiao did not do it in the room where he lived like last time, but chose to open another room, and also carried out special treatment. Even Ling Xiao called Zhou Qian over to help her change her clothes and do some things that were inconvenient for Ling Xiao.

In this way, not only did the monitoring system prepared by Natasha completely fail, but even if she wanted to do something, she couldn't do it because of Zhou Qian's stumbling block, after all, there was Ling Xiao staring at it from the side.

Leaving Ling Xiao's room, the more Natasha thought about it, the more aggrieved she became, she Natasha Romanoff was a mysterious person, a famous black widow, if it weren't for her identity not to be exposed, I'm afraid she would have led someone to arrest Ling Xiao a long time ago.

Sitting in the car, the anger in Natasha's heart gradually subsided, frowning, thinking back to what happened tonight, Natasha was a little unsure, whether it was her identity that was exposed, or whether the hands and feet of those people in the General Bureau during the day in Ling Xiao's room were discovered by him.

Natasha was more inclined to the latter point, Ling Xiao might be a little suspicious of her, but the two didn't have much contact, it seemed that the hands and feet of those people in the General Bureau were discovered.

Ling Xiao is not an ordinary person after all, judging from his treatment of him twice, the other party obviously has some special means, according to Natasha's experience, Ling Xiao has mastered more like ancient martial arts from the East, this time when Natasha did data sorting out Ling Xiao, he had already found out.

But now it seems that it should be more than that, Natasha began to really take an interest in Ling Xiao at this time.

"Ling Xiao, what you were doing in the room just now is your business in New York?" Zhou Qian looked at Ling Xiao with some curiosity, when Ling Xiao gave Natasha skin care before, except for the beginning and the end when she helped to change clothes, Zhou Qian did not participate in it, but waited alone in the living room.

"Well, you also know my identity as a TCM physician, who has some special medical methods, and has some reputation in skin care, Miss Pepper of the Stark Group, and Miss Natalie just now, are my clients." Ling Xiao explained a little to Zhou Qian, the reason why he brought her here for the first time was because he felt that his relationship with Zhou Qian would definitely not be able to hide Natasha, and with the means of S.H.I.E.L.D., I am afraid that many things would have been investigated a long time ago.

Natasha's purpose is naturally impossible to hide from Ling Xiao, which is not difficult to guess. Her purpose is to get close to and win over Stark, which can be seen from Coulson's initiative to send the super-soldier serum; Second, it is natural to grasp and infiltrate the progress of the Stark Group, even if there is no malice, it has become a habitual action of S.H.I.E.L.D. agents, and Tony Stark's condition must naturally be taken into account.

Ling Xiao used the excuse of giving Pepper skin care at the same time, and secretly treating Stark, which is also not difficult for S.H.I.E.L.D. methods to detect.

Ling Xiao still remembered that when he first met Natasha, the other party had already tried to knock on the side. Natasha's identity as Pepper's assistant is very confusing, if it weren't for Ling Xiao hearing some familiar names, a face similar to Eastern Europe, and an outstanding figure, I'm afraid that Natasha would really have to probe a lot of things from him.

If it was said that it was to probe Stark's condition before, but today when he came to find himself, Ling Xiao could feel that Natasha was eyeing him.

But now it's different from half a year ago, Ling Xiao's cultivation strength has soared, not to mention, there are all kinds of troubles within S.H.I.E.L.D., Iron Man, mutants, transformers, since Tony Stark revealed his identity, the whole world seems to have suddenly become chaotic, all kinds of accidents have emerged one after another, S.H.I.E.L.D. can't take care of it at all, even if he is targeted by them now, Ling Xiao won't care too much.

"Can I do this kind of skin care?" Zhou Qian's eyes flashed with curiosity.

"Of course." Ling Xiao looked at the curious Zhou Qian in front of him, and a strange smile appeared on his face.

The next morning, when Zhou Qian woke up, it was already nine o'clock in the morning, and she couldn't help blushing again when she remembered the tricks she had done in the nursing room last night.

Fortunately, at this time, Ling Xiao was not in the room, Zhou Qian covered her face and sat on the bed for a while, then got up and walked to the bathroom.

That afternoon, Ling Xiao took Zhou Qian to reorganize her clothes from top to bottom on Fifth Avenue, and she was going to attend the opening ceremony of the Stark Expo tomorrow night, but she couldn't wear too shabby.

Ling Xiao would go to the Super Soldier Serum Research Center every day to sit for an hour or two, paying attention to the progress of the research, and occasionally he would do some research. For the super soldier serum, Ling Xiao is also curious about what is the source of this serum?

Is it true that Dr. Erkins artificially concocted it through a recipe, as recorded in history?

When Dr. Erkins died, the recipe was lost due to absolute secrecy, and only he knew about it. In the decades that followed, no one could replicate his equations, and even if many people followed his ideas to study serums, no one could perfectly replicate a super soldier like Team America.

Ling Xiao always felt that things were not so simple, whether Dr. Erkins's serum was really made by himself, or was it made by getting the blood of a certain strong man and removing the cellular components and fibrin.

It's a pity that the gods and demons list didn't have the slightest reaction to the super soldier serum, otherwise Ling Xiao would have been able to take this opportunity to get a glimpse of its roots.

In order to concoct the existing super soldier serum to the desired goal that everyone needs to achieve, a lot of experiments need to be done. However, it is far from the time to conduct in vivo experiments, and Professor Derek Ross is still studying the ratio of the various components, making the most suitable equations, and then adjusting them through experiments, which may take some time, and this time is not short.

In the past two days, Ling Xiao has not seen Natasha, not even Stark and Pepper, and the closer to the opening of the conference, the busier the two become.

With Stark Expo reheld after a gap of decades, Tony and Pepper exhausted their respective relationships, and the world's top 500 companies basically set up their own counters at the expo venue.

In addition to Stark Industries, two of the world's three largest industrial giants, Osborne Industries and Cruise Industries, are also involved.

In addition, Hammer Industries, Roxon Corporation, Oracle, Speight, Pym Technology, Worthington Industries, Wayne Group, and other famous companies in the United States and even the world have set up special counters here to display their top technology products.

When Ling Xiao took Zhou Qian to the fair's site in Flushing, it was already dark, so they went straight to the main hall of the expo, but it was already crowded here, and on the booth, there were 20 hot beauties dancing, and the noisy music resounded throughout the hall, and the atmosphere was very warm.

Ling Xiao wore Stark Industries' identity badge, so it was easy to enter the backstage of the arena and meet Pepper, Natasha, and Hogan.

"Congratulations, Miss Potts, the fair was a success." Ling Xiao greeted with a smile and asked, "What about Mr. Stark?" ”

"Tony? Isn't this coming? As she spoke, Pepper subconsciously looked up at the night sky, and at this time, a flash of fire pierced the sky.
