Li Hao didn't go home for three days, and went to work in the scientific research temple early in the morning every day, which was the first time since he took office, and the reason why he came to the scientific research temple so early in the morning on the third day was to wait for He Jie's report.

It's a pity that he waited until noon, He Jie's report has not been delivered, Li Hao guessed that he was probably encountering some difficulties, so he personally went to the scientific research office to find He Jie, and saw Li Hao looking for him in person, He Jie was a little flattered, and hurriedly saluted, but was stopped by Li Hao's hand.

Although Li Hao was anxious, he still had to pretend to be very casual and asked, "He Jie, can the salt drying report I asked you prepare yesterday be written?" ”

He Jie bowed his head and said: "I am ashamed of my humble position, although I have thought of a general method, but there is still a major problem that has not yet been solved, and it seems that I cannot make a complete plan for the time being." ”

"Oh? Really? Li Hao raised his eyebrows and said indifferently, "Show it to me." ”

He Jie hurriedly returned to his bookcase and showed the plan he wrote to Li Hao, Li Hao nodded and praised while reading: "Yes, your idea is very good, very good......

He is sincerely admired, because He Jie's plan has captured the essence of the salt drying method, and the method used is basically close to the salt drying method of later generations, and the problem he said is the establishment of the salt drying field, the salt drying field can basically only be established on the seaside or the edge of the saltwater lake, and it must be very large, covering an area of hundreds or even thousands of acres of land, so the salt production rate is high, but the problem also arises, such a large salt field, how to store seawater, it is definitely impossible to use manpower, and it is still not possible to use water trucks, too slow, This is also the major problem that He Jie said.

After reading it, Li Hao closed his report, nodded and smiled: "I have a solution to the problem you said." ”

He Jie's eyes lit up when he heard this, and he was overjoyed and asked, "What is the magic method of my lord?" ”

Li Hao smiled mysteriously and said: "Yantian impounds water, why do you need manpower, doesn't the sea water rise and fall by itself every day?" ”

He Jie was stunned when he heard this, and then suddenly patted his head: "Ouch, how did I forget this, I didn't think of such a simple thing." ”

"Don't get too happy." Li Hao said with a smile on his face, "Sun salt can indeed quickly get a large amount of salt, but the salt that comes out should be salt crystals and cannot be eaten directly." ”

"Yes, my lord said very much, the boiled salt crystals must also be filtered out of debris to get refined salt." He Jie nodded in agreement with Li Hao's words.

Hearing this, Li Hao patted his plan in his hand and said, "You haven't had time to write a method for purifying filter residue in this plan, well, I think our method of purification and filtration must also be improved." ”

"Improving purification methods?" He Jie frowned when he heard this and asked, "What magic does your adult have?" ”

Li Hao smiled and said, "There is no magic method, but there is a stupid method, do you want to listen to it?" ”

He Jie hurriedly bowed his head: "Listen to your ears." ”

Li Hao said: "Since we plan to open a salt field, we will set up more salt ponds, one pool after another, one level after another, layer by layer filtration, and the more it is improved, the purer it becomes." ”

He Jie nodded and groaned when he heard this: "Although this method is a bit unflattering, it requires a lot of manpower and material resources to build many salt ponds, but it is a one-and-done method. ”

"That's why I said it was stupid." Li Hao smiled and said, "Let me remind you, whether it is seawater or saltwater lake water, there are toxins, if you want to filter it, you must have a very good filter material, I know a material, the filtration effect is wonderful, and most importantly, the price is low, very low." ”

He Jie asked with a puzzled face when he heard this: "What is the material?" ”

Li Hao smiled proudly: "Charcoal." ”

"Huh?" He Jie was a little confused when he heard this, that black thing can filter seawater? It feels kind of like a joke.

Li Hao saw that he didn't believe it, so he said: "If you don't believe it, okay, I'll do an experiment for you to see, you go to the kitchen to find some charcoal and salt water." ”

"Yes." When He Jie heard this, he hurriedly took the order and left.

It didn't take long for He Jie to bring a basin of salt water and a section of charcoal that was almost complete.

Li Hao smashed the charcoal, then took out two medical gauze masks that he carried with him, wrapped the charcoal in it, found a vase over, washed it inside, and then said to He Jie: "You grab a handful of mud and sand, and put it in salt water." ”

He Jie ran outside the house and grabbed a handful of mud and sand, and in the salt water, the salt water suddenly became turbid, Li Hao put the gauze mask on the mouth of the vase, and then poured salt water on the gauze, the turbid salt water entered the vase through the gauze, although a lot of salt water spilled out, but it didn't matter.

Soon, a basin of water was poured, the vase was almost full, and there was still a little mud and sand left in the basin, Li Hao poured a little water to wash the basin, and then poured the salt water in the vase back into the basin, He Jie suddenly exclaimed "wow", only to see that the salt water in the basin was clear, and there was no slightest sense of turbidity, it was simply amazing.

"Well, believe it now." Li Hao looked at He Jie with a smile.

"Believe, believe." He Jie nodded excitedly, as if he had seen the beautiful situation of Qingyan popularizing the Tang Dynasty.

Li Hao threw away the gauze, patted He Jie's shoulder gently, and said, "You write a complete salt drying plan, give it to me in three days, and I will help you revise and improve it and submit it to the emperor." ”

"The Emperor...... Emperor...... Emperor? He Jie was pleasantly surprised when he heard this, and he was so excited that his tongue didn't listen to him, and he said in disbelief, "Big ...... My lord, do you mean...... Will the emperor see the recital written by the humble position? ”

"Of course." Li Hao nodded solemnly, "I will personally ask for credit for you, as for how the emperor rewards you, it depends on your luck." ”

"Thank you, sir!" He Jie was so excited that he knelt on the ground, kowtowed deeply, and said, "Thank you for your cultivation!" ”

Li Hao bent down to help him up, patted him on the shoulder again, and said: "You don't have to be like this, we are in the scientific research temple, we have to work for the benefit of the people of the Tang Dynasty, maybe you will sit in my position one day, but you must not forget your heart, our scientific research temple exists for the Tang Sheji and the people of the Tang Dynasty." ”

He Jie was moved for a while when he heard this, and said: "The adult is righteous, and the lowly duty is ashamed of himself, and the lowly duty in this life must be based on the adult's admonition, and do not forget the original heart." ”

"Hmm." Li Hao smiled with satisfaction and said, "You prepare the plan, I'll go home first, three days later." ”

Li Hao took Lu Yun and Jin Li back home, he didn't go home for three days, and he had a lot of troubles as soon as he went home, the Hu brothers asked him to report the business status of the newspaper and the bank, Xue Rengui reported to him the progress of Zuo Wuwei's training, Du Hong asked him to report the family's financial income and expenditure, and Feiying came to report on Wu Meiniang's recent situation......

After dealing with them, Li Hao finally breathed a sigh of relief, first went to the bathhouse to take a bath, and then went to his own private room to rest, Gulina and Elena came to help him massage, one pressed his back, the other pressed his feet, that was called a comfortable one, alas, first put aside his ambitions and enjoy life.

Just when Li Hao was happily enjoying life, the eldest grandson Wuji was already facing the saint in the Ganlu Temple, making a statement to Li Shimin and interceding on behalf of the prince, after all, Li Chengqian had been grounded for several months. The reason why the eldest grandson Wuji interceded for Li Chengqian was actually instructed by Li Shimin, why didn't he take the initiative to bring it up himself? It can only be said that the emperor is a creature...... is more peculiar, too face-loving, Li Shimin is one of the best, since he ordered Li Chengqian to be grounded, then the proposal to lift the ban naturally cannot be put forward by himself, otherwise he will be suspected of being slapped in the face.

The eldest grandson Wuji said a lot of reasons, in a word, the prince has performed well recently, he has realized his mistakes, and the punishment of the grounding can be over, Li Shimin naturally will not object, after all, he instructed the eldest grandson Wuji, so he agreed with the boat.

Li Chengqian, who was finally lifted, was not much moved, on the contrary, he was resentful, during this time he did not reflect as well as the eldest grandson Wuji said, but indulged in singing and dancing every day, bought drunk every day, and after getting drunk, he went to spoil the male pet he raised, I don't know why, his sexual interest in men is higher than that of women, to say that he has the good of Longyang, it is not counted, he occasionally pampers the princess or some other women, anyway...... Men and women can eat it.

Li Chengqian's most resentful thing is Li Hao, the reason goes without saying, and the second is to resent Wei Zheng, because this old thing actually dares to impeach himself, and he also resents Li Tai, the dead fat pig-like brother actually covets his position as the prince, and he doesn't take a good look at himself in the mirror, can the supreme throne accommodate his fat ass, and finally, he still resents Li Shimin, why do he still favor Li Tai so much after making himself the prince, making him very insecure, making himself irritable, and irritable to the point of being almost manic.

Wei Zheng, Li Tai, and Li Shimin are either high or powerful, and he can't move, except for Li Hao, Li Hao's position is not high, and his power is not heavy, and at the same time he is Li Chengqian's most resentful person, once a person has a grudge against another person, he will forget the reason why he resents him, and then he will become more and more resentful.

This is the case with Li Chengqian at this moment, his resentment towards Li Hao has reached a peak, and he even forcibly put the reason for his grounding this time on Li Hao's head: If it weren't for dealing with Li Hao, how could he be grounded.

Although he was just lifted, Li Chengqian didn't care at all, he wanted to deal with Li Hao, it was a big deal to be grounded again, how big it was, as long as he could kill Li Hao, he felt that all this was nothing.

Li Chengqian thought about it at home for a whole day, and finally came up with a clever plan, this clever plan may not be able to kill Li Hao, but it will definitely allow Li Hao to enjoy the disaster of prison again.

The next morning, an official of the East Palace quietly walked out of the East Palace and entered Fengle Fang, which is a very famous entertainment district in Chang'an City, where most of the shops are gambling houses, restaurants, green buildings, theaters and other leisure and entertainment places.

In this small Fengle Fang, there is such a head snake, called Yu Santai, known as the third master, when he was young, he walked the rivers and lakes, and his martial arts were good, and later gathered a group of little brothers, dominated Fengle Fang, opened a few gambling houses in Fengle Fang, and collected Feng Le Fang protection fees by the way, and in recent years in Chang'an.

After entering Fengle Fang, the official of the East Palace came to the Santai Gambling House, found the person in the gambling house, and handed over a huge gold cake to see Santai.
