"Oh, how do you say that?" Hearing Liu Xu's words, several old people who were originally a little disappointed couldn't help but be curious and asked again.

"This breakthrough is enough to make Printon return in vain," Professor Huang also said to Liu Xu at this time.

Hearing Professor Huang's words, the eyes of several old people instantly shifted to Professor Huang, expecting him to give a reasonable explanation.

"The most difficult part of the Locke formula is that it is like a stone ball, so that people can't find loopholes to crack it, and Xiao Xu's calculation this time is quite a hammer for everyone, as long as it takes a while, this stone is only afraid that the pump will collapse," Professor Huang said at this time.

"So principal, you will sit firmly in the Diaoyutai this time, and I am now looking forward to the day that is coming. At this time, Professor Huang said excitedly.

"President Liu, you can just watch the play safely this time, of course, in front of everyone, in the end, Beijing University will "help" Printon solve the problem that Printon has been helpless for a hundred years, what kind of scene do you say this will be?"

"It's a pity that this time it's just to make Plinton ugly, if it's really completely cracked, then this time Printon will definitely go back in disgrace. At this time, Professor Huang said with some dissatisfaction.

But when he said this, Professor Huang couldn't help but look at Liu Xu, and rolled his eyes at Liu Xu, 7.3 million fans can get it so easily, but if Liu Xu's idea is known to everyone, they all have to have the urge to kick him.

At this time, after being explained by Professor Huang and Liu Xu, the old men couldn't help but relax, but then they also looked at Liu Xu expectantly.

"It's almost not straightened out, maybe tomorrow, maybe it will never be cracked," At this time, Liu Xu of course knew what the old people meant, and couldn't help but say helplessly.

Everyone was a little disappointed when they heard Liu Xu's words, and then they couldn't help but feel relieved, this is the mystery of mathematics, even the mystery of every science, sometimes it takes a little bit of luck to succeed.

"But this is already very good, this time I want to take a good look at William's constipated face," at this time Old Man Liu said fiercely.

At this time, several old men couldn't help but smile bitterly when they heard it, they all knew that Plimpton's matter had put a lot of pressure on Old Man Liu, and now he really wanted to vent.

"Xiao Xu, you have done a good job in this matter, you have the appearance of an executive officer," At this time, Old Man Qiao also patted Liu Xu's shoulder with a smile and said, he really didn't expect Liu Xu to give them such a big surprise.

Liu Xu didn't say anything when he heard this, just smiled at the old man, the reason why he traded with the system was largely because of Liu Xu, who was also a hidden "angry youth".

"Old Qiao has come down to eat?" Just when many old people in the house were excited, Teacher Ning's voice suddenly came.

"Lao Liu, Lao Wen, let's go down to eat, and when the next thing is waiting for the remote video, we will decide with the group of old guys," at this time, Old Man Qiao said loudly.

"Okay, let's go down!" Hearing Old Man Qiao's words, Principal Wen said with a smile, at this time they have the initiative, so there is no need to worry too much.

Several old men also nodded in agreement, and turned around to go downstairs, "Wait," at this time, Old Man Liu suddenly shouted.

"Old Liu, what else do you have to do?" asked Old Man Qiao at this time.

"When you eat later, don't talk about cracking the Locke's formula," said Old Man Liu as he looked at everyone.

As soon as everyone heard this, they also understood that this matter should be as secret as possible, so as not to save Princeton from detecting anything.

"Don't worry, Lao Liu, we all understand the importance of this matter," said Old Man Wen at this time, and everyone else nodded.

After getting a satisfactory answer, Principal Liu didn't say anything and went downstairs first, and Old Man Qiao looked at the anxious Old Man Liu and shook his head helplessly and followed.

"Teacher!" At this time, only Liu Xu and Wu Lao were left parked by the stairs, and Liu Xu couldn't help shouting.

"You've done a good job, but don't push yourself too hard," said the old man with great relief, and then turned and walked downstairs.

Liu Xu looked at the old man's back and couldn't help smiling, although the old man rarely smiled at him, he had always played the role of a strict teacher, and rarely leaked a tender side in front of him.

"Come, come! Xiao Xu sits here," Before Liu Xu came down, Mrs. Huang hurriedly greeted Liu Xu and said, at this time, Huang Shanling couldn't help but have a headache when she saw her mother's movements.

However, the others smiled kindly, at this time, Mrs. Huang looked at Liu Xu, and it was the mother-in-law looking at her son-in-law, and the more she looked at it, the more satisfied she became.

However, at this time, Liu Xu was frightened by Mrs. Huang's enthusiasm, and was a little stiff and pulled to the dinner table by Mrs. Huang, and several old people couldn't help laughing when they saw this scene.

They didn't expect that Liu Xu, who was still scolding Fang Xuan just now, would also have such an embarrassing and stiff time.

"By the way, Xiao Xu, do I remember that your cooking is delicious? Don't miss two hands today?" At this time, Old Man Qiao said with a smile, he also saw that Liu Xu was a little restless, so he gave him an excuse so that he could hide.

"Yes, yes, I'm going to cook two dishes for everyone," At this time, Liu Xu heard Old Man Qiao's words, and ran to the kitchen like greasing on the soles of his feet, he had never been so fast.

"You, you, this table full of dishes is not enough to eat, don't you want Xiao Xu to be in trouble?" Seeing Liu Xu's back, Teacher Ning looked at Old Man Qiao and said complainingly.

"The child is willing to be filial, what is the block!" said Old Man Qiao at this time, but everyone couldn't help laughing when they heard this, they all knew how tired Liu Xu was.

At this time, Mrs. Huang also reacted, knowing that she was overly enthusiastic this time.

"Okay, don't ask that little guy, let's eat first!" At this time, Old Man Qiao said with a smile, although Mrs. Liu Xu was still a little worried about Liu Xu, but it was not good to stop the principal's face.

"Don't worry, that kid can cook and cook well, and he can still be hungry?" At this time, Wu Lao also saw his wife's worries, and said comfortingly.

If he hadn't seen Liu Xu's cooking skills, maybe he wouldn't be better than his own wife at this time.

Hearing Wu Lao's words, although Mrs. Liu Xu looked at the kitchen suspiciously, she finally chose to believe Wu Lao's words and did not go over to help.

……

At this time, Liu Xu, who walked to the kitchen, couldn't help but lean against the wall and breathe a sigh of relief, he really hadn't seen the scene just now, so he was at a loss for a while.

But now it doesn't seem to be anything, at this time Liu Xu began to look through the refrigerator, and just now he told the group of old people that he was going to leak his hands, so he couldn't go out empty-handed for a while.

Fortunately, Mr. Ning has prepared all the dishes today, and there are still leftover beef and mutton in the refrigerator, so Liu Xu plans to use them to make "sauce mutton" and "beef stewed potatoes", and now the weather is a little cold, and these two dishes are just right for several old people.
