If you say that you have paid, then there will definitely be a gain, but it is just a matter of whether you will gain more or less.

Li Yuanba didn't have time to wait for photosynthesis to collect oxygen, so he had to retreat to the next best thing to collect oxygen by boiling aquatic plants.

Not to mention, he really collected some of it, but this oxygen is not very pure, but something is better than nothing, right?

With a carriage of almost twenty robes and air bags that were already filled with impure oxygen, Li Yuanba pulled the utensils for making oxygen, as well as the little eunuchs in the house, and walked into the palace.

Taiji Palace, in the Lizheng Palace.

Seeing that the Chinese New Year is coming, Li Shimin has a lot of things to deal with, but in order to be able to accompany Empress Changsun more, he simply moved the location of government affairs from the Liangyi Hall to the Lizheng Palace.

"Guanyin, what do you say Yuan Ba asked the supervisor to do? Why do you have to use transparent water jade? After Li Shimin finished handling the government affairs at hand, he sat on the edge of Empress Changsun's bed, took her hand and said.

At this moment, the eldest grandson empress's face was much more ruddy compared to the morning, she shook her head lightly, and said, "Your Majesty, in fact, after seeing Yuan Ba yesterday, the concubine felt like a different person. If it weren't for His Majesty's concubine, Yuanba had been sealed in Xuanbing for many years, I'm afraid the concubine would still think that he was another Yuanba! ”

Not to mention that women's intuition is very accurate! If Li Yuanba heard these two words of Empress Changsun, I don't know if he would be frightened. Urine past.

"Hahaha, I feel that way too!" Li Shimin laughed, and then his voice became a little low, "But this change is obviously developing for the better, and now, I don't want him to be able to retrieve those memories from the past." ”

Empress Changsun understood what Li Shimin was thinking at the moment, and she must have thought of her late eldest brother and third brother again.

She grabbed Li Shimin's big hand tightly and did not speak.

At this moment, Liu Sanshui ran into the inner hall with small steps, respectfully saluted Li Shimin, and said, "Your Majesty, His Royal Highness King Wu wants to ask to see the queen!" ”

"Oh? This kid will be in a hurry, and I and the queen have just talked about him, and he is here! Li Shimin was happy when he heard it, and said, "Go and pass him in!" ”

"No!"

Liu Sanshui responded and hurriedly threw out the Lizheng Palace.

Within a minute, I heard a brisk footstep coming in, and just after entering the inner hall, Li Shimin, who was sharp-eyed, saw two bulging things in Li Yuanba's arms at a glance.

Li Shimin raised his eyebrows, and without waiting for Li Yuanba to speak, he took the lead in asking: "Yuanba, what is the thing you are holding in your arms?" I look familiar, huh? ”

Li Yuanba handed one of the air bags to Li Shimin, patted the other air bag and said: "Brother Huang, this thing is called an air bag, which is specially made by the craftsmen who will be the prisoners, and it is specially used to carry gas. ”

"Gas?" Li Shimin said with some doubts: "What is the use of this thing with gas?" ”

"Brother Huang, do you remember that your brother once mentioned oxygen?" Li Yuanba said with a smile: "The thing in this air bag is the oxygen that my brother ordered people to step up the production of. And this oxygen can make the second sister-in-law breathe quickly when she is not breathing well! ”

"Oh, really?" Li Shimin's eyes lit up, he looked at the air bag in his hand, and said, "How to use this thing?" ”

Li Yuanba pointed to a cow tendon tube sewn together with the airbag on the edge of the airbag, and said: "Brother Huang, as long as you untie this cow tendon tube and put it in your mouth, you can suck out the gas inside, but you can't rely too much on this thing, this thing can only be used for emergency purposes!" ”

Li Shimin nodded clearly, then untied the cow and handed it to Empress Eldest Sun, and said, "Guanyin, you give it a try!" See how it feels? ”

Empress Eldest Sun bowed slightly, took the air bag handed over by Li Shimin and took a sip gently, and after a moment, Empress Eldest Sun's beautiful eyes flashed with a hint of surprise, and said: "Your Majesty, this, this is really incredible!" After so many years, it is the first time that the concubine feels so breathing! ”

"Really? That's good, that's good! Li Shimin also looked happy.

"Brother Huang, I made a total of twenty air bags this time, and I also brought into the palace a few little eunuchs in the palace who knew how to make oxygen, as well as that set of utensils! If these air bags are all sucked up, the royal brother tells them to continue to do it! ”

Li Yuanba looked at Li Shimin and his wife happy, and he was also very happy in his heart, at least the first step was to ensure that the life of Empress Changsun was done, and the next step was to find the medicine king Sun Simiao.

As long as Sun Simiao can be found, then the illness of the eldest grandson queen will definitely be cured, and the eldest grandson queen will not die, which means that history has really changed, and then his own butterfly will be able to completely flutter in the Tang Dynasty!

"Yuanba, this time it's really thanks to you! If it weren't for you, I might be separated from your second sister-in-law forever! Li Shimin is in a good mood now, unprecedentedly good, he looked at Li Yuanba and said, "Yuanba, tell me what you want?" As long as you want, I can give it to you! ”

"Sister, I'm asking you for the country, are you willing to give it to me?" Li Yuanba secretly scolded himself in his heart, but his face pretended to be seriously considerate, and only after a while did he say: "Brother Huang, speaking of which, the younger brother really has something to ask you!" ”

"You and my brother, why do you use the word begging?" Li Shimin waved his hand and said, "I just said, you saved your second sister-in-law, just mention whatever you want!" ”

"Then I'll say it!" Li Yuanba glanced at Li Shimin, and said solemnly: "Brother Huang, I want the daughter of my Tang royal clan to never marry Fanbang Waiyi!" ”

The smile on Li Shimin's face froze, as if he had been struck by lightning, and a pair of originally handsome faces began to distort and change, cloudy and uncertain. After a while, Li Shimin sighed and said, "Fourth brother, do you know that my Datang is going to make peace with Xue Yantuo?" ”

Fourth brother!

This time, Li Shimin was not called Yuanba, but the fourth brother, so whether it was from the change in title or the change in tone, Li Yuanba could hear the resentment, anger, helplessness and bitterness in Li Shimin's words.

"I know, it's Cheng Qian who sued me!" Li Yuanba's voice was a little flat, and he directly lifted Li Chengqian out.

Li Shimin paused for a moment, then shook his head, and said, "Chengqian, this kid, this is a grudge against me!" ”

"I'll go, don't pit my eldest nephew!"

When Li Yuanba heard Li Shimin's words, he thought that this cheap brother was going to clean up Li Chengqian, and was thinking about how to exonerate Li Chengqian, but he heard Li Shimin continue:

"Cheng Qian doesn't approve of harmony, I know! Not to mention him, even I can't convince myself! ”
