Li Er looked at Yiqiē in front of him, his mind was blank, and he didn't even react to the three of Li Chengqian's eavesdropping in the dark just now.

Seeing this scene, Li Kuan put down the big stone in his heart slightly, but he didn't expect that there were three more insiders, which was really difficult to do.

Li Er didn't have to be in a trance for long, he reacted, after all, he was a person who had experienced a lot of things, he just couldn't accept it all at once before, but now he can calm down when he slows down. Seeing the four little ghosts in front of him, Li Er's first reaction was that this matter must not be said: not to mention this magical scientist, this is understandable, it is just a magical means, Taoism and Buddhism have similar means, Li Er was shocked that he knew the secrets behind these methods, and knew that it was not something that a child could do, and it was even more impossible for his son who had always been weak and sick to do it. In addition to this, the most fatal thing is the previous explanation of the dragon, which must not be passed on, otherwise it is likely that the entire Qin Wangfu will suffer.

"You three, why are you here?" Li Er's face was flat, and his gloomy face showed that the master was very angry at the moment.

"Father!" The three Xiaozheng were too low to look at Li Er, they were arguing about right and wrong before. Li Er and the others came over suddenly, giving them a feeling of being broken and doing bad things, so they could only hide, who knew that these things would happen later.

"You can't say a word about what happened today, you know? If someone knows only a few words, the entire Qin Wangfu will not exist if it is impossible to say it! Father, your mother, your aunts, your brothers and sisters! You know? Li Er said in the strictest tone to the three little Zhengtai. He didn't know how to prevent the news from leaking out, and he couldn't attack his son, so he could only let them know the threat and hope it worked.

"Father, how's it going? Doesn't this qiē prove that scientists do have the means to penetrate the heavens? Li Kuan knew that most of the things had happened, but he didn't get a reply from Li Er, and he wasn't sure.

"As a father, but I have seen it, but you can be sure that this 'scientist' can really be used by my Datang? How could he choose you as his successor? And can Datang really control this force? "Li Er is very suspicious of the purpose of this 'scientist' approaching Li Kuan, you must know that in the entire empire, there are few things that he Li Er wants to know can be hidden. But this 'scientist; But I didn't have any impressions, and I couldn't even find any clues. It was simply impossible, and it was in this place where he cared the most, after touching his son.

"Father, this boy knows a lot! Although the child is a mysterious teacher, he has never shown his superiority to the world, but because he has been living alone in the world, he looks down on secular power and the like, and it can be said that he has no desire for power at all, which is certain, otherwise with their strength, they can make earth-shattering waves in any dynasty. Li Kuan explained.

"Why, Kuan'er is so sure? Maybe there are some things in history that you 'scientists' sat down under some other skin? Li Er still couldn't let go.

Li Kuan was speechless, could it be that he didn't have any 'scientists' who had a garbage system in his buddy's body? If you really say that, Li Kuan is destined to become a guinea pig, waiting to be sliced and studied, and still thinking about recuperating his body and doing something in Datang!

"This, the child can't guarantee it, the child can only guarantee that the child will never do something dangerous to the Tang Dynasty, and even when some seniors in the division do things that are dangerous to the Tang Dynasty, the child will stop it!" What else can Li Kuan say, he can only follow Li Er's train of thought.

"Oh well! You should be able to contact your master, just say that your father wants to talk to him and see if they can cure your Aunt Pingyang. Li Er also knew that his son had done the maximum he could, and for such a mysterious organization, it would not be bad to have such a result, as for other Li Er, it was impossible for him to sue Li Kuan, he would secretly arrange it. For this organization called 'Scientists', Li Er didn't have much confidence in believing that they would be well-intentioned, and he never minded using the worst of his mind to figure out others.

"Alright! Kid, contact the teacher! Li Kuan said, but he didn't move, just stared at the three Zhengtai around him.

At this time, the three little Zhengtai had already finished feeling guilty, they heard Li Er say it so strictly, and they were really shocked in their hearts, but when they thought about it, they didn't say it, it wasn't nothing. So they don't have to worry anymore, and in such a family, they naturally know what they can and can't say, and what to say to whom. So even the youngest Li Tai made up his mind that this matter would rot in his stomach and not reveal the slightest. It's just that in their hearts, they are a little in awe of Li Kuan, which they haven't found out themselves, and they just feel that Li Kuan is included in the door wall by the mysterious academic school, which is a very enviable thing. Li Tai, the little chubby dun, even stretched out his fat little hand and grabbed Li Kuan's hand to see how his hand hid such a big bag. It's just that he didn't see a name for himself when he looked left and right, and he was very disappointed, because he also wanted to learn, so that he could take his favorite sauce beef to the school.

Seeing Li Kuan's hesitation, Li Er knew that he didn't want his three brothers to know more secrets, so he asked the three little Zhengtai to go back by themselves, and he personally sent them out of the small garden.

Li Kuan saw that the three little Zhengtai were too far away, so he pretended to close his eyes and sat cross-legged on a stone on the side of the road.

When Li Er came back and saw Li Kuan like this, he knew that he was contacting the mysterious 'scientist'. So I didn't bother, just waited quietly.

"You're Kuan'er's father?" An old voice came out of Li Kuan's mouth.

"Huh? Who are you? Li Er saw that Li Kuan actually said such a thing, and his voice was as old as the voice of an old man in his seventies and eighties, and asked in surprise.

"Don't you want to talk to the old man? Now the old man will talk to you through Kuan'er's body! Li Kuan continued.

"You're Kuan'er's teacher? The mysterious scientist? Li Er would not suspect that Li Kuan would talk to him like this, so this voice must be Li Kuan's teacher, but how did he make his own voice through Li Kuan's body?

"Yes, the old man is the twelfth generation of scientists! And Kuan'er is the thirteenth generation! An old voice came out of Li Kuan's mouth and continued to flicker Li Er.

"Then dare to ask the old gentleman's name!" Li Er's attitude was a little more respectful, and this method was somewhat similar to the legendary immortals, which made him unconsciously become respectful.

"The old man's name must have been forgotten by the world over the years, the old man's famous Chen Jun!" Li Kuan didn't know what kind of name to give his teacher, so he borrowed the name of Chen Kuan's ancestor who gambled on Huashan with Zhao Kuangyin in later generations.

"Chen?" Li Er was puzzled again, he had never heard of this unfamiliar name.

"It seems that most people in the world are forgetful, hehe...... Maybe the old man's name was deliberately erased! Thinking that the old man was also a powerful figure, Emperor Wu of Liang gambled with the old man and lost a mountain land. I wanted to admit his love, but I didn't expect him to turn around and believe in Buddhism, trying to use those bald men to deal with the old man, which is really ridiculous. Just those guys who only know how to hide copper coins in the temple, can they deal with the old man? Li Kuan said nonsense, when he was studying history in junior high school, he knew that Emperor Wu of Liang worshiped Buddha, so he told a story.

"This ......" Li Er had to think more, Emperor Wu of Liang admired Buddhism is known to the world, but there are many emperors who worship Buddhism, but none of them are as crazy as him, and even became a monk in the Buddhist temple three times and was bought back by the imperial court with money. has achieved a ridiculous allusion of 'monk selling the emperor'.

Li Er didn't want to believe it, but he felt that there seemed to be some truth, Emperor Wu of Liang was deceived by this incognito 'scientist', and instead hoped that the Buddha with boundless power could help him get rid of this great enemy in his heart, which was not impossible. It's just that why didn't this history write about this 'Chen Tuo'?

"The old man knows that you will be suspicious, but if you look at the contents of that bag, you should be able to make a decision!" Li Kuan stretched out his hand and pointed to the bag on the ground, which was the remaining twenty points after the fifty energy points were exchanged for the huàn voice changing skill last time.

Li Er squatted down and picked up the bag on the ground, opened the mouth of the bag, and looked at the golden grain inside: "What is this?" ”

"This is Zhancheng rice, which is produced in a place called Linyi, which is now south of Jiaozhou in the Tang Dynasty. This thing can be ripened twice a year, and even three in Yuezhou or further south in Guangzhou, Yongzhou. Presumably it is of some help to the current Datang! "Li Kuan had twenty energy points left last time to exchange this Zhancheng rice, and he originally wanted to exchange it with huàn hybrid rice, but it didn't work, and Datang's productivity could not meet the technological needs of hybrid rice. It can only be exchanged for the Zhancheng rice that is stored in this era, and it is not cheap, and a little energy point is only given a catty.

"This ......" Li Er didn't know how many times he was speechless today, he looked at the rice seeds in his hand, and felt a little indescribable. Datang now lacks everything, lack of people, lack of money, lack of food, lack of war horses. It's just that what is this Champa rice is really that good? And two crops a year, or even three crops a year, is it too exaggerated. The millet planted in the Guanzhong Plain, wheat can only be planted once a year, if it is replaced by this Zhancheng rice, the grain output of the Tang Dynasty will not be greatly increased! It's just that the seeds are a little less! And what about the yield?

"Dare to ask the old gentleman, what is the yield of rice in this Zhancheng?" Li Er asked when he thought of it.

"Yield? One season should be no lower than wheat. It's just that it requires more water than wheat, and only a small part of Guanzhong can be planted. Li Kuan also doesn't know whether the Guanzhong area can grow rice, but the Han people are the best people in the world to farm, no matter where they are, they have to plant something on the land, and they can grow it well, so these are handed over to the old farmers who have planted in Guanzhong all their lives.
