"Poof...... Cough...... cough ......" Professor Qian was directly choked by his own saliva.

Liu Lao next to him was no better, his eyes were wide open, and he looked at Jiang Yanhai with a shocked expression, and at this time, Li Ruobai, who was secretly hiding in the distance, walked out of his hiding place with a smile and walked over quickly.

Walking to "Jiang Ling", Li Ruobai stretched out his hand and grabbed her arm, and said with a smile: "Grandpa Liu, Grandpa Qian is good." ”

"Xiao Li, how are you, are you here? To put it this way...... Is this really Xiao Jiang? When Professor Qian and Professor Liu saw Li Ruobai, a kind smile appeared on their faces, but this still couldn't stop their shock.

Jiang Yanhai looked left and right to confirm that there was no one around, so he lowered his voice and said in his original voice: "Two old professors, this is me." ”

Hearing Jiang Yanhai's original voice, the shocked expressions on the faces of the two professors were a little numb, and they looked Jiang Yanhai up and down again, really, it can be said to be flawless.

Of course, it can't be said to be perfect, and if you go through the kind of security inspection machine that can completely display the internal structure of the human skeleton, there is still no way to hide it.

However, even then, it's not impossible, what's the matter, haven't seen Thailand come back?

"You...... Awesome, really, you kid is really an elite in all industries, if you are in the fashion circle, you should also be considered a powerful person. Liu Lao gave Jiang Yanhai a thumbs up with emotion.

"Ahem...... That's it. Jiang Yanhai coughed dryly twice and resumed Jiang Ling's voice.

"Your voice ......"

"It's a ventriloquist technique." Jiang Yanhai explained in a low voice.

"I've never believed that there are perfect people in the world, but you kid...... It's really about to break that perception. "Professor Qian couldn't laugh or cry, they are old, they can't stand this stimulation, you are a little too scary.

A man can perfectly disguise himself as a woman, how difficult it is, although they are not professional in this aspect, but they also know how much it is.

Especially in terms of voice and Adam's apple, these are two relatively big difficulties, but Jiang Yanhai can be said to have solved them perfectly.

"Come on, come on, let's go, go in and introduce you to the professors, these professors who arrived today are all you have seen, and it is absolutely safe here, don't worry about your identity being exposed, but tomorrow there will be professors from other research institutes coming over, they don't know your identity, and you will be Jiang Ling at that time!" Liu Lao beckoned and said.

"Yes!" Jiang Yanhai spoke in a serious tone.

After following Professor Liu into the room, Jiang Yanhai found that there was a table of old professors sitting in this private room, a large table of 18 people, which was basically full, and Jiang Yanhai had seen them before.

Professor Li, who is in his 80s for several years, also came.

When they watched Professor Liu and Professor Qian come in with Li Ruobai and a strange woman, these old professors immediately thought of something, and the expressions on their faces instantly became weird.

The people who can sit here can be said to have no low IQ, Professor Liu and Professor Qian went out to pick up Jiang Yanhai's disguised person, and they all knew this, at this time, the two old guys came in with a strange girl.

You don't have to think about it to know that this girl is Jiang Yanhai's disguise, not to mention that there is Xiao Li next to her to testify.

When they arrived at the table, everyone's expressions were a little weird, and Liu Lao immediately smiled when he saw everyone's expressions and said, "Come on, come on, you kid introduce yourself." ”

"Hello professors, my name is Jiang Ling." Jiang Yanhai spoke directly, of course, in his changed voice, "Of course, I am also Jiang Yanhai." ”

The last half of the sentence was spoken in his original voice.

The inside of this private room is absolutely safe, and Jiang Yanhai has already scanned it with an advanced scanning system.

All these old professors here have seen him, and they all know what his situation is, so it's okay to say it.

Hearing Jiang Yanhai speak in two different voices, although all the old professors guessed it, they were still stunned.

"Come on, come on, let me see." Professor Li, who was beside Jiang Yanhai, immediately smiled and beckoned.

Jiang Yanhai also simply walked over and sat down beside Professor Li, who reached out and grabbed Jiang Yanhai's hands with some curiosity.

Although Jiang Yanhai treated his hands with some cosmetics, he could still feel some calluses in his palms.

This is also Jiang Yanhai's physical fitness, so that his skin is much better than others, if it were other people, the disguise of his hands would not be so perfect, such as Chen Shanming's hands are very rough, and when disguising, they can only be considered from the identity of the disguise.

"You kid...... A little bit of a skill to ...... It's almost impossible to see. Professor Li's old voice said with some amazement.

"We must learn this from camouflage-infiltrating reconnaissance behind enemy lines." Jiang Yanhai said with a smile in Jiang Ling's voice.

"Hahaha, good, good, good, you kid is the top in all fields, genius is genius, okay, we're relieved to see you like this, we old guys are still thinking about how to cover for you." Professor Li immediately said with a smile.

"Thank you." Jiang Yanhai stood up again and bowed to all the professors.

"No thanks, thank you, you kid do more results, what's the point of covering for you, by the way, do you have time to deal with the follow-up matters of your engine?" Professor Qian looked at Jiang Yanhai and asked.

"I'm afraid I don't have time in the future, Professor Qian, if you don't have a research plan in the next step, I think the design of my new engine should be designed into a series, and some of its internal structures actually sacrifice some performance, enlarge its volume, and its thrust will also increase."

"If it is chosen on some large, such as stealth bombers, the volume requirements for stealth are not so high, then the volume of the stealth bomber it can push will be larger." Jiang Yanhai immediately spoke.

When Jiang Yanhai finished studying the design drawings of the entire engine, he had already discovered this, and the Phantom series engine was definitely not just this one model.

Any engine design can be developed into a series.

"You've thought about that?" Professor Qian's eyes lit up immediately.

"I have considered it, my design drawings about the engine, every detail of why I designed it this way, the principle of the design, I have marked it, and I will send it to you when the time comes." Jiang Yanhai replied very simply.
