"Even if it cannot be used on a large scale, this hot air balloon will definitely become a powerful weapon to defeat the enemy——"

Although it was not as good as he had expected, Li Shimin quickly adjusted his mentality.

After all, even if it is used as an auxiliary means, this hot air balloon will definitely become a surprise weapon and even a killer weapon.

From now on, the fortified city cannot be defended, and the ambush cannot be sustained.

From a high position, the enemy will be visible at a glance.

Even if two armies confront each other, with the support of air power, they will have the advantage.

As soon as Li Shimin said this, everyone couldn't help but nodded, and then looked at Wang Zi'an.

"Zian, how long can your hot air balloon fly in the sky?"

Li Jing looked at Wang Zi'an with burning eyes. As the commander-in-chief of the army, he was more aware of the role of the hot air balloon in the army.

"This depends on the amount of fuel. Although I am using special coking coal, which has better performance than ordinary coal, the endurance is not very good. Did you see that it can only continue to fly with such a big pile on it?

More than half an hour - it's a pity that we can't find oil and natural gas. Otherwise, I guess I can fly all morning without any problem..."

Thinking of this question, Wang Zi'an couldn't help but shook his head regretfully.

Without gas tanks and oil, it is almost impossible to achieve the battery life of the previous life.

Without oil, coal would still not work.

He was sorry, but others didn't think so. They all looked at the hot air balloon on the ground in shock and gasped.

This thing can carry people flying in the air for more than half an hour!

If we find what he calls oil and natural gas, we can fly all morning!

This is simply unimaginable!

"That's enough, that's enough -"

Several people couldn't help but nodded excitedly, as if they saw the spectacular scene of a large number of hot air balloons flying above their own army.

Wang Zi'an knew what these people were thinking and glanced at them speechlessly.

"Don't think too much. This thing is easily affected by the weather, and it is a consumable item. The cost is not low, especially the fabric used to make the hot air balloon. It is specially processed and is hard-earned. Didn't you see it?

It took several days to sort out two——"

Having said this, Wang Zi'an clapped his hands.

"So, it's okay to get one for fun, but I'm afraid it won't be easy to deploy it on a large scale - ok, ok, there's nothing good to see, let's go, let's go -"

Wang Zi'an stood up very simply and waved to Xue Rengui to put the hot air balloon away.

Because, he found that if he didn't put it away, it might be taken away later. Others could say that he had little confidence in the integrity of his two father-in-laws.

He watched helplessly as Xue Rengui took the hot air balloon away.

Li Shimin and Cheng Yaojin couldn't help but look away regretfully, and cursed secretly in their hearts for being stingy.

This bitch is getting stingy.

Shouldn't we donate such a good thing first so that my father-in-law can experience it first?

Based on everyone's wishes, the lunch banquet was held in the back garden.

Li Yuan and Zhang Jieyu, Li Shimin and Empress Changsun, Li Jing and Hong Funu, plus Li Xiaogong, Du Ruhui, Qin Shubao, Cheng Yaojin, Niu Jinda, Kong Yingda, Yu Zhining, Zhang Ruosu, Lu Deming, Yan Shigu, Ouyang Xun, Yu Shinan, etc.

The boss's banquet was set up in a glass greenhouse.

As for the rest, including Changsun Wuji, Fang Xuanling, Wei Zheng, Tang Jian, Li Junxian and other young people, they were all arranged outside. There was no way, who made them the accountants of His Majesty's family?

In fact, according to their official status, Li Shimin and Empress Changsun were not qualified to sit inside, but they were the father-in-law and mother-in-law of the host family, so this couldn't be justified.

Although the back garden of Chang'an Marquis Mansion is picturesque, with lights and colorful lights everywhere, and floor heating, I don't feel cold when I sit there.

But sitting with a group of young people still made Changsun Wuji feel a little uncomfortable.

Fortunately, he was not the only one who felt uncomfortable. Young people like Cheng Chumo, Li Siwen and Fang Yiai were also uncomfortable. They consciously avoided his table with Fang Xuanling, Wei Zheng, Tang Jian and Li Junxian.

.

Otherwise, he might be even more upset if he is really crowded onto the same table.

"Oh - you think, when will this end?"

Changsun Wuji smiled bitterly and picked up the tea cup on the table and took a sip gently.

Fang Xuanling, Wei Zheng, Tang Jian and others couldn't help laughing or crying when they heard this.

At first I thought it was just a small episode in the human world, but I didn't expect to be played by the human world. I followed His Majesty and fell into this pit, and I can't climb out.

That's not right. His Majesty has a daughter who successfully landed ashore, while people like me are still in the pit...

Thinking about it, it’s really heartbreaking.

…

Glass greenhouse.

The atmosphere is much better.

After this period of growth, courgettes and beans have climbed all over the shelves, green cold melons have become fist-sized, and leeks, spinach, lettuce, eggplant, shepherd's purse, and okra are all lush and green.

What attracted everyone's attention even more was the patch of "red fruits", which at this time were quietly covered with branches.

In particular, a particularly tall plant has a red fruit on top, which looks particularly attractive.

"Is this the legendary Zhu Guo?"

Li Yuan looked at the tomato that was almost red and couldn't open his eyes.

Wang Zi'an couldn't help laughing when he saw that his saliva was about to flow out. He walked over, reached out and took it off, walked to the sink next to him, gently unscrewed the water pipe, and the clear cold water flowed down.

In order to make it easier to water the fruits and vegetables in the greenhouse, he specially had a water tower built. Now, it is convenient for washing things.

"Brother, you are so lucky. When I came over to check it out two days ago, it was not yet ripe - come on, try it and see how it tastes -"

Although he has not been able to eat tomatoes for a long time, he is not ready to compete with an old man.

Li Yuan couldn't help but be overjoyed when he heard this. Under the envious gazes of Li Shimin and all the big guys, he took it over with joy and took a bite. Then, the expression on his face instantly turned a bit astonished.

Seeing everyone looking at him expectantly, he quickly chewed two mouthfuls and swallowed, and then looked at Wang Zi'an in confusion.

"Didn't you mean that the red fruit melts in your mouth and leaves a fragrant aroma on your lips and teeth? Why does it look a bit weird when I eat it..."

The prince was happy when he settled down.

Where is this fruit that melts in your mouth?

Bring me a basket!

"No, I mean, brother, who did you listen to -"

"Yun Xuzi! Taoist Master Yun Xuzi once told me that this Immortal Zhu Guo can not only revive the dead but turn flesh into white bones, it also melts in the mouth and leaves a fragrance on the lips and teeth. It is a rare Taoist holy product and can prolong life.

The effect of strengthening the body..."

Wang Zi’an:……

Yun Xuzi is simply poisonous.

This is all what I communicated with Li Yuan!

I've told you so many times not to associate with that great bastard Yun Xuzi, but you don't listen. Is it over now?

"How many times have I said this, this is a tomato, not a red fruit in Taoist legend. You must not believe it, but now you believe it -"

Although everyone did not want to believe it, the fact was before their eyes, and the Emperor's expression was enough to explain everything. Everyone could not help but show a hint of disappointment in their eyes, especially the elderly men such as Li Gang, Ouyang Xun, Yu Shinan and Yan Shigu.

To say that I'm not disappointed would be an absolute lie.

At this age, who doesn’t want to live longer and stay fit?

Seeing that something was wrong with the atmosphere in the greenhouse, Wang Zi'an sighed helplessly.

Yun Xuzi, this great stickman, should be beaten to death.

"But don't be disappointed. Although these tomatoes can't prolong life or strengthen the body, they taste pretty good. They are a good choice whether they are stir-fried or eaten directly. When they are ripe, I will give some to everyone to try -"

Wang Zi'an said, laughing.

"If you really want to keep fit and prolong your life, that's not impossible. I also have some special black donkey skin donkey hide gelatin here. I'll give some to you later. Go back and try the effect -"

As soon as Wang Zi'an mentioned this, several old men became interested on the spot.

Ordinary people may not know it now, but among the top elite circles in Chang'an, who doesn't know that the products produced by Wang Zi'an must be high-quality products. As a miracle doctor in Chang'an who is reluctant to take action easily, if he says that he can prolong life and strengthen his body, then he must

It can prolong life and keep fit.

"Zian, don't be alone. We old guys don't take your money for nothing. Just tell us the number and we will buy it directly from you -"

Li Yuan patted Wang Zi'an on the shoulder very proudly.

Seeing the Supreme Emperor speak, several other old men also nodded.

It is definitely not a long-term solution to expect such good things from others, but buying them is more reliable.
