    But she was still ignorant of such a magical thing as ice-making in summer, and was very curious.

    "Come on, listen carefully."

    "Today I will give you a good lesson."

    "Teach you the methods and principles of how to make ice."

    Lin Xuan said calmly after hearing the words, preparing to give them a chemistry class.

    Changsun Wuji, Empress Changsun, and Li Lizhi immediately pricked up their ears when they heard the words, listening carefully. Even Li Shimin looked at Lin Xuan seriously.

    All four of them were very curious about this.

    What kind of magical method can produce ice cubes in this hot summer day against common sense?

    Seeing this, Lin Xuan gave a dry cough and cleared his throat.

    "Ahem"

    "Actually, the method of making ice is very simple."

    "Only two materials are needed."

    "One is water, and the other is calcium nitrate, commonly known as saltpeter."

    "As far as I know, water will freeze when it is cold, and saltpeter will absorb a lot of heat when it dissolves in water."

    "So, you only need to dissolve a large amount of saltpeter in the water, let the saltpeter absorb the heat in the water, and the water will become very cold, and it will freeze!"

    Lin Xuan slowly talked about the method of making ice in summer, and told them the chemistry knowledge he had learned in high school.

    "I see!"

    "Brother Xuan, your knowledge is really profound!"

    "You even know such a miraculous thing!"

    "I heard that saltpeter is used by Taoist priests to refine elixirs, but I didn't expect it could be made into ice!"

    Changle suddenly realized after listening to Lin Xuan's detailed explanation.

    Being smart, she immediately understood the principle of ice making. Her big beautiful eyes looked at Lin Xuan, full of admiration and admiration!

    As soon as this remark came out.

    Lin Xuan's expression turned cold when he heard the words, and he said a little indignantly: "Using saltpeter to make elixirs is purely harmful!"

    "Saltpeter is a heavy metal, and it must not be eaten by the human body!"

    "Once ingested too much, it will seriously damage people's health and even endanger their lives!"

    "You must never take this poisonous elixir in the future."

    Speaking of this elixir, Lin Xuan hurriedly told them.

    As a modern person who believes in science, Lin Xuan still dismisses the pills refined by ancient Taoist priests.

    He knew that alchemists in ancient times liked to add some heavy metals to their medicines.

    People may be fine after taking it for a while.

    But after a long time, it will definitely cause serious damage to the body after long-term use, and even endanger life.

    It is estimated that the reason why Qin Shihuang died so early may be because he was too superstitious about the elixir of life, and he took too much of these elixirs with excessive heavy metals.

    How could there be an immortality elixir in this world?  !

    Birth, old age, sickness and death, human nature, everything is the law of natural development.

    Some drugs can delay aging and death.

    "Yeah, Lizhi knows it!"

    "I won't take pills. What's more, there is such a powerful invincible doctor as Brother Xuan by my side, so I don't need to take any pills!"

    Feeling Lin Xuan's care and entrustment, Li Lizhi was deeply moved immediately, and nodded happily in response.

    Li Shimin, Empress Changsun and Changsun Wuji also nodded one after another, taking Lin Xuan's advice to heart.

    Afterwards, Li Shimin couldn't hold back the excitement in his heart, and commanded Wei Ran to the internal servant Chang Boss who was waiting at the door: "Chang Boss!"

    "Immediately order someone to fetch some water and bring some saltpeter."

    "I want to see with my own eyes the spectacle of freezing ice in summer!"

    Regarding Lin Xuan's words, he no longer doubted them.

    But I still want to see this magical ice-making spectacle with my own eyes!

    "Obey, Your Majesty!"

    Just when Manager Chang was about to take orders to leave.

    "Wait a minute!" Lin Xuan stopped loudly.

    "Your Majesty, my people have already gone to get it!"

    "You don't need to trouble Manager Chang!"

    "They will be??Something was taken.  "

    Lin Xuan said lightly to Li Shimin.

    Li Shimin waved his hands when he heard the words, and said majesticly: "Director Chang, you don't have to go."

    "No!" The chief servant Chang replied reverently outside the door.

    Woohoo!

    Almost revealed it!

    If Li Shimin finds out that he has bought all the saltpeter in Chang'an City, I don't know how he will feel?

    Will you lose your temper?

    Lin Xuan thought about it, one thing more is worse than one thing less, and it is better to make a lot of money by yourself first.

    soon.

    A group of Lin's servants came in carrying a large basin of water and a large basket of saltpeter.

    Seeing that the water and saltpeter were all in place, Li Shimin immediately said to Lin Xuan impatiently: "Qinglong King, all the materials you need are here."

    "Hurry up and let us open our eyes and see the wonder of this summer ice!"

    As soon as this remark came out.

    Empress Changsun, Changsun Wuji and Li Lizhi all looked at Lin Xuan eagerly, their faces full of expectation.  (Remember the site URL: www.hlnovel.com
