Time is like an hourglass, going on, from August to October, the weather changes from hot to cool, and soon it will be a harsh winter, you must know that the ancient harsh winter was not a joke.

Of course, the harsh winters of ancient times had no effect on the rich, who had cotton clothes and were very warm.

And probably in the Qin Dynasty, there were already "fireplaces" and "fire walls" in the palace, and Qin Shi Huang had a special fireplace to keep out the cold, for the bathroom and ordinary heating. The smoke vents of the fireplace and the fire wall are placed outdoors. The method of fire wall is to make the cylinder tiles interlock to form a pipe, and then bury them in the wall, which is the prototype of heating.

Later, this practice spread to the people, and of course the rich would build these for heating, and in addition to these, there were also high-end equipment such as braziers, foot stoves, and smokers.

The poor will not be able to do anything, they will have nothing but to resist the winter, and many poor people will freeze to death in the cold winter because it is too cold.

Li Zhan was working on two things during this time... Honeycomb coal and coal furnaces... The brothers and sisters of the seventies and eighties must be no stranger to these two things, heating, boiling water, cooking... It is best to use a coal stove with honeycomb coal.

The most important thing is that it is cheap, and now Datang also burns coal, but the coal burned by Datang is the kind of lump coal, which is placed in a brazier, which can only be used for heating, and has no other use at all, and the price is also expensive.

There is also cheap coal, which is crushed coal, which cannot be burned, so the price is very cheap.

Li Zhan's honeycomb coal can perfectly solve these problems, plus the coal furnace, it is perfect, the most interesting thing is that the honeycomb coal and coal furnace will definitely hit Chang'an's lump coal business to the bottom of the left, and the lump coal business is also the Cui family.

In addition to Li Zhan's research on honeycomb coal and coal furnaces, one more thing is to study four-wheeled carriages, for more than a month, the road in Chang'an has been repaired, and this time the perfume is too profitable.

Li Zhan can now produce 40,000 bottles of perfume a day, that is, 400,000 guan a day, 12 million guan a month, Li Zhan sent half of the 6 million guan into the palace Li Shimin's inner son, Li Shimin danced happily that day.

followed two into two million 400,000 tubes, and entered the Changsun Mansion, one hundred and twenty guan belonged to Changsun Wuji, and one million 200,000 guan belonged to Li Liqian, and the same amount of money as a small mountain directly made Li Lizhi dumbfounded.

Yes, it is true that Li Lizhi is a princess, but she has never seen so much money as a princess, one million and two hundred thousand yuan, and Li Lizhi can't close her mouth when she looks at this money.

There are also one hundred and twenty times sent into the East Palace, to be honest, this money has really aroused the covetousness of many people, and some people have already stared at it, of course, these people are not staring at Li Chengqian, they are staring at Li Zhan.

Li Zhan also earns a lot of money in a month, one percent of perfume, 1.2 million guan, Qingfeng Lou and Qingfeng Casino together have one million guan, of which Qingfeng Lou is 300,000 guan, and Qingfeng casino is 700,000 guan.

There are also 1.2 million pieces of soap and soap, 50,000 pieces of cement... There are other miscellaneous things, fine salt, ice, alcohol, etc... That's 150,000 in total.

Li Zhan's total income in a month is 3.7 million guan, and Li Zhan's expenses are not small, in addition to Dunhuafang and Zhushan, the monthly expenses are about 700,000 guan.

So Li Zhan's monthly income is three million yuan.

These three million guan are too tempting, so slowly some people began to think about Li Zhan, Li Tai, Li Ke... There are also some bastards from the big families, all of whom are eyeing Li Zhan.

However, because Li Zhan recently took over a project with Li Shimin, these people are lurking.

What kind of project did Li Zhan take, that is, to ask Li Zhan to provide cement, Li Shimin wanted to pave Chang'an City into a cement road, and it has been going on for more than half a month, and a small half of Chang'an City has been paved, and the money is paid by Li Shimin's nephew and the household department.

The people are very happy with this measure to benefit the people, after all, the concrete road is paved, so there is no need to get dirty when it rains in the future.

The most eye-catching thing in the past month or so is that the Lotus Society has grown stronger and stronger, and the number of believers has expanded to 30,000, and there are already many officials, internal servants, and even military generals.

This sign, which no one has paid attention to now, is a big hidden secret.

Originally, Li Zhan would have noticed, but what caught Li Zhan off guard was that Li Zhan was going to be stabbed in the back by someone from the Li family in Longyou.

................................

Longyou Li Family... The head of the family, Li He, officially retired to the background, although he was still the nominal head of the family, but the big and small things in the family were basically in the hands of Li Cheng, and Li Cheng was also very powerful.

Li Cheng has his own business in the Western Regions, the business is very good, and later Li Zhan's soap and soap were also handed over to Li Cheng for sale, and he was successful in the Western Regions, Li Zhan made more than one million yuan in soap and soap a month, in fact, some of the money was earned by Li Cheng.

There are hundreds of thousands of guan a month, Li Cheng is also very atmospheric, at least eighty percent of the money of hundreds of thousands of guan is given to the family, but unfortunately Li Cheng has done this, but the people of the Li family in Longyou are still not satisfied.

Among the representatives are Li Jian and Li Zhuo's sons.

"The third... This month, I heard that you got 3,000 kan, which is really a lot...! "The one who spoke was Li Kong, the eldest grandson of the Li family in Longyou.

And the one who was called the third child was Li Jian's eldest son Li Muxiu...!

"Phew...!" Li Muxiu took a sip and said, "Three thousand runs... If my father is here, I will only get 3,000 a month. ”

"It's just...!" At this time, it was Li Zhuo's son Li Dayyang who spoke.

"Li Cheng, bastard... After coming back, he directly grabbed the rights of the uncle's head of the family, and then used small favors to envelop those guys in the family.

Give us the things between his teeth a month, and want us to be grateful to Dade, don't dream, last time I asked him to hand over the management of soap and soap in Jiangnan to me, he didn't do it, and all the business was handed over to Li Jing'an.

That's a woman, why is she in charge of our Longyou Li family's business, she will still marry in the future. After finishing speaking, Li Yangyang was angry.

"Hey...!" Li Kong also sighed at this time and said: "My father is actually helpless, Li Cheng is menacing, my father can't let it, but my father's biggest regret is that he didn't save the second and fourth uncles."

That's right... Did you know... My father heard that Li Cheng also got the right to operate the perfume, and now Li Cheng is going to make a lot of money again. ”

"Perfume...!" After Li Kong finished speaking, Li Muxiu and Li Yangyang's eyes lit up, because now there is no one in Chang'an who doesn't know perfume, everyone knows that perfume is in demand in Chang'an, and no one thought that Li Cheng would get the right to operate perfume in his hands again.

Looking at Li Muxiu and Li Dayyang's bright eyes, the corners of Li Kong's mouth inadvertently showed a faint smile, he knew that the fish was hooked, and he would follow his father's order in a while, step by step, let the fish bite the hook firmly and catch it directly.

This is Li Kong's first time cheating people, and he wants to do it simply and beautifully!
