Research on internal combustion engines is progressing faster than expected, using a temperature-controlled pressure array to control the release of methane from combustible ice, and then using a spark plug to ignite the gas to propel the cylinder. Now the overall structure has been designed, but there are two key points that have not been solved, one is the battery, and the other is the control conversion of the temperature control pressure array, which requires two different temperatures, one for refrigerating combustible ice, and one for rapid heating and release of methane gas.

When Jiang Xingchen was discussing with a group of researchers, the old man rushed in, and as soon as he entered the door, he shouted: "Boy, there is great news!"

Jiang Xingchen raised his head when he heard the voice, and when he saw the old man's expression, he knew that he couldn't continue his research today, so he said to several researchers: "That's it for today, you guys have to hurry up and study lead-acid batteries these days, and I will be responsible for the formation here!"

The researchers got up and left. Jiang Xingchen looked at the old man and said with a smile: "So happy, you have been promoted to the Great Perfection!"

"Damn, how do you know?" The old man's smile suddenly froze on his face, he still wanted to surprise Jiang Xingchen, but he didn't think that people would guess it as soon as he opened his mouth!"

"It's hard to guess, just by looking at your happy face, you know that you have been practicing hard these days, and you have benefited a lot from absorbing spiritual energy!" Jiang Xingchen said lightly.

The old man waved his hand: "If you guess, you can guess, but do you know my current strength?

"Bragging!" Tang Chuxue also entered the house at this time and interrupted the old man by interjecting.

"What am I bragging, Pink was punched out by me for hundreds of meters, isn't it defeated? The old man jumped as high as he could, and his tone was a little sharp.

Jiang Xingchen shook his head at Tang Chuxue, who was about to speak, arched his hand to the old man, and said lightly: "Then congratulations!"

The old man was really unhappy this time, and said loudly: "What kind of attitude do you have, I'm promoted to the Great Perfection, aren't you happy?"

Jiang Xingchen said puzzledly: "You were promoted to the Great Perfection and I was not promoted, what is there to be happy about?"

"Damn, little bastard, you did it on purpose, didn't you?" The old man shouted, Jiang Xingchen's light appearance made his heart burn.

Jiang Xingchen smiled and said, "It's just a promotion to the Great Perfection, there's nothing to show off! With that piece of spiritual flesh here, we will cultivate more Great Perfection in the future!"

After saying this, Jiang Xingchen turned his head and asked Tang Chuxue: "You said yes, daughter-in-law?"

"That's right, Xiaoxiang, Mei'er, Mo Hongxian, Zhao Danqing, they all have hope!" Tang Chuxue also smiled and fought the old man with Jiang Xingchen.

The old man was so aggrieved that he snorted heavily, turned around and was about to go out.

But at this moment, Tang Chuxue's expression suddenly changed, and her smile slowly converged, and she changed to a dignified expression.

"What's wrong?" Seeing the change in Tang Chuxue's expression, Jiang Xingchen chuckled in his heart, and an ominous feeling came to his heart, and he hurriedly asked.

"I don't know, I suddenly feel a fluster, I don't know what went wrong!" Tang Chuxue shook her head slowly.

The old man's footsteps also stopped, and he turned his head and asked, "First snow girl, is there something wrong?"

Jiang Xingchen didn't say a word, he raised his legs and ran out, what he thought at the moment was that something might have happened to Xingchen Ling, so Tang Chuxue could feel it. In addition, it is also most likely that something will happen to the star leader, because there is the largest mercury ball in the house, which is likely to attract the silver-robed man.

He hurried out, preparing to send a telegram to his home asking about the situation. Tang Chuxue and the old man followed him closely.

But just as they were about to rush to the telegraph office, a young man ran out in a panic and almost didn't hit Jiang Xingchen.

"Be careful!" The old man dragged the young man aside and reprimanded: "Why are you so frizzy, don't you look at it when you walk?"

The young man was startled, looked up and saw Jiang Xingchen, and immediately shouted: "Sir, I was about to send you a telegram." There was a big incident in Minggang City, saying that the laboratory exploded and Miss Xianning was seriously injured!"

"What?" Jiang Xingchen's mind exploded, as if he had been struck by lightning, all consciousness disappeared in an instant, and he didn't hear what the young man said afterwards.

The old man and Tang Chuxue were also stunned, like Jiang Xingchen, they all thought that something was wrong at home. Unexpectedly, it was Xianning, who set up an industrial base in Minggang City.

After a moment, Tang Chuxue came back to her senses, turned her head and saw Jiang Xingchen's appearance, she couldn't help but be a little worried, and pushed him hard: "Xingchen, Xingchen!"

Jiang Xingchen suddenly came back to his senses, looking extremely anxious and irritable, and said loudly: "Call Pink, let's hurry to Minggang City! By the way, hurry up and send a telegram to home, and let Xin'er bring someone to rush there!"

At this time, Jiang Xingchen was really a little flustered, he didn't judge that something happened at home before, because he had already made arrangements, and it was for the silver-robed people, although he was worried, he was not flustered. But Xian Ning's accident was different, and he felt that his heart was throbbing.

Tang Chuxue understood Jiang Xingchen's mood at the moment, and did not persuade him, a long howl rushed out of his mouth, like the roar of the Nine Heavens Phoenix, resounding throughout the Cursed Land.

After a while, a chirping sound rang out, and Pink's huge body fell from the sky and landed in front of them.

As soon as he saw the old man, the pink anger didn't hit one place, and he had to say a few sarcastic words when he opened his mouth. But before he could speak, a figure rushed over and jumped on its back.

Pink turned her head and just saw Jiang Xingchen's gloomy face, and swallowed all the screams that came to her mouth. It has never seen the boss like this, and it can see that its liver trembles when it is careful, and if it makes the boss unhappy at this time, the consequences will be very serious.

Tang Chuxue and the old man followed Jiang Xingchen and jumped on Pink's back one after another, and said loudly: "Pink, go to Minggang City, quickly!"

Pink didn't dare to say more, let out a long roar, flapped her wings and flew into the air, and disappeared into the sky in an instant.

At this time, Han Xiaowu also rushed over when he heard the movement here, and when he saw the young man who was still stunned in place, he frowned and asked, "What happened?"

The young man came back to his senses, hurriedly handed the telegram in his hand to Han Xiaowu, bowed down and said, "Something happened in Minggang City, the laboratory exploded, and Miss Xianning was seriously injured!"

"What?" Han Xiaowu was shocked by the news, lowered his head and looked at the telegram carefully, and his heart sank suddenly. The importance of Xian Ning to the Star Collar is self-evident, once something goes wrong, it will not only be a huge loss to the territory, but also a huge blow to Lord Jiang.

"Sir, Miss Tang and the old man have already gone to Minggang City on pink just now, and they told me to hurry up and send a report to Xingchenling, so that Miss Xin'er can also bring someone to rush there!" The youth continued.

Han Xiaowuyi shouted when he heard it: "Then don't hurry up, report a fart here!"

As he spoke, Han Xiaowu grabbed the young man and ran into the telegraph office in two steps (to be continued.) )
