Take a deep breath and feel instantly refreshed. Pen & Fun & Pavilion www.biquge.info

"Oxygen, it's good oxygen, and the purity is quite high!" The hot spring muttered to himself, and said to the queen: "Queen Mother, this oxygen has some lime astringency, which may be slightly pungent, but it is not harmful to inhale the body. ”

Suddenly, a drop of water dripped down the parchment bladder and onto the mouth of the hot spring.

The hot spring felt that the water droplets were a little hot, so he wiped the water droplets, and said to himself: "This chemical reaction, heat production is also first-class!" It's definitely wonderful to warm your baby in winter! ”

Although it is said casually, the hot spring thinks this idea is wonderful, and the disposable baby warmer patches used by people now are derived from the concept of chemical heat production!

However, the ancients were accustomed to using soup pots, and soup pots are still relatively safe, relatively speaking, this kind of chemical reaction heat production method, the ancients may not be able to accept it.

"Girl, how are you feeling......

The queen mother saw the reaction of the hot spring, and the panic in her heart had disappeared, and she wanted to try the oxygen produced by the hot spring as soon as possible, what it tasted like.

"The folk girl feels refreshed now, as if she had never breathed well before." Hot Spring smiled slightly, she deliberately exaggerated, so that the queen could fight early.

When the queen heard this, her eyes did become more longing.

"Tell the girl, this sheepskin bladder is also full!" A little eunuch excitedly pinched the opening of the sheepskin bladder and came to the hot spring to report.

The density of pure oxygen is greater than the density of air, if you want to use oxygen slowly, as long as you put the sheepskin bladder on the front, you can slowly squeeze it out when you want to use it.

"Let's give Hongu a try!" The queen mother called to the little eunuch, a little anxious, "Cai'er, help the palace bring the sheepskin water bladder." ”

The little eunuch respectfully handed the sheepskin bladder to the scarlet-clad maid, and then retreated to the crowd to continue to help.

"Girl, it doesn't seem to be bubbling in the water!" The maid who had been listening to the movement of quicklime in the water said.

"Add quicklime!" The hot spring instructed: "If the water is no longer bubbling, or if the bubbling speed is slowing down, open the lid of the porcelain and add new quicklime to it!" ”

"Do you want to take out the original lime?" A maid asked.

Hot Spring shook his head and said: "No, the original quicklime has become mature lime, which will not affect the chemical reaction of quicklime, and the heat energy produced by them will definitely hurt your hands, and it is inconvenient to take it out, so you can continue to add quicklime to prepare oxygen, and the original things do not need to be changed." ”

Obviously, there is more water prepared in the basin, and when the quicklime is consumed, the oxygen generation will gradually decrease, as long as the quicklime is added, so that the quicklime and the water continue to react chemically, the oxygen can be prepared continuously.

The scarlet-clad maid hung a sheepskin bladder on the queen's nose, and a fresh gas with a slight lime smell came to her nose, and the queen did not feel the pungent smell of lime, but felt that her brain was immediately much clearer.

The effect of this thing is obviously a hundred times better than that of green plants!

The queen couldn't wait to take a few more sips and really felt the refreshment described in the hot springs.

When the hot spring turned around, he found that the scarlet-clothed maid was learning the posture she had just done, holding a sheepskin water bladder to give the queen oxygen.

"If you use it for the queen's mother, the sheepskin bladder is coming to get it, the oxygen will slowly overflow, if you feel that it is not enough, you can also squeeze the sheepskin bladder with your hands, and squeeze out a lot of performance at a time!" The hot spring hurriedly corrected the posture of the scarlet-clad maid.

The scarlet-clad maid nodded and complied, and the queen suddenly felt that the oxygen was not so strong, but her body was still relaxed and very comfortable.

"Pure oxygen inhalation time should not be too long, too long time will cause oxygen poisoning." The hot spring kindly reminded: "Don't use it at night, lest you light the lamp and candle, and the fire source may be uncontrollable and may produce an oxygen explosion." ”

"Poisoned? ...... explosion," the scarlet maid gasped, "what is this thing good or bad?" ”

"Oxygen is so useful, it depends on how it is used." Onsen further explained: "But don't worry, although oxygen is heavier than air, it will still dissipate when exposed to air for a long time, and we use this clumsy method to produce oxygen, which is extremely slow, even if we light the lamp and candle, the oxygen concentration does not reach, and it will not explode the house." ”

"This palace understands, the girl is an unpredictable prophet, take precautions, and tell all the advantages and disadvantages of this fairy qi, lest we do the wrong thing."

The queen's spirit is much better, she was disgusted with Wenpo Hot Springs before, and even wanted to kill her, but now she admires her very much and trusts her.

Luo Yinu's method is not as effective as the method of the hot spring, and the queen is a little glad that she didn't do anything to the hot spring, otherwise the head disease can entangle her to death now.

The queen also suddenly realized, no wonder Concubine Jing can be cured by the hot springs, her weird recipes really work, I don't know where she learned it!

"Tell Niangniang, Imperial Doctor Jiang has arrived!" A maid came in from outside to make an announcement.

The scarlet-clothed maid was a little angry, and said sarcastically: "Our mother is almost ready, the Imperial Doctor is really timely!" ”

"Let him in." The queen's complexion was not very good, and the prescriptions prescribed by Imperial Doctor Jiang became less and less useful.

Imperial Physician Jiang slowly walked into the inner room, bowed down in front of the queen, and said, "The queen forgives her sins!" The prince of Anguo's family just fell ill and had severe delirium, and the prince ordered Weichen to quickly diagnose and treat, which delayed the work! ”

The scarlet-clothed maid looked at the maid who had made the report, and the maid confirmed: "When the slave maid went to find Imperial Doctor Jiang, the prince was about to go out, so he ordered the slave and maid to wait in front of the house and not disturb Imperial Doctor Jiang to treat the prince. ”

After listening to the maid's explanation, the queen dissipated some of her anger, "Imperial Doctor Jiang, please get up, this illness in this palace really bothers you." ”

"Wechen is terrified!" Imperial Physician Jiang didn't want to contact the queen in his heart, and he could also sense the queen's displeasure at this time.

"Hurry up, listen to how the girl uses medicine, and study hard!" After speaking, the queen closed her eyes and quietly inhaled oxygen to relieve the pain of her head disease.

Hot Springs said in her heart, the queen really thinks highly of herself, if she lowers the status of Imperial Doctor Jiang in the queen's heart because of this incident, she will naturally not be able to!

"Niangniang, the prescription of the Imperial Doctor is right, and the people don't know how to use medicine!" Seeing that the queen was too lazy to speak, Hot Spring said: "Without the Imperial Doctor, these little tricks of the people are in vain." ”

The queen opened her eyes slightly, and said softly: "Imperial Doctor Jiang's medicine is really useless to this palace. ”

When Imperial Physician Jiang heard this, he trembled, and the queen's tone was cold, as if she was saying that Imperial Physician Jiang was useless, and the queen could kill him at any time. (To be continued.) )
