Time flies, and it has been more than a year since Lei Shan returned to Leijiabao in a blink of an eye.

During this time, he ran around, first with Tiangongtang and Momen jointly opened a number of factories in some big cities, on the bright side there are mechanical smelting and casting factories, mechanized textile factories, mechanized food factories and other industries closely related to people's livelihood, in the dark, Lei Shan is in the depths of the mountains to build several arsenals, in addition to the guns of the Lei family's old business, under Lei Shan's slightly spoiler explanation, the mass production of aircraft and tanks is also on the agenda under the efforts of Ma Benzai, Zhang Xuan and other patriots and people with lofty ideals in Tiangongtang and Momen.

In addition, a pharmaceutical factory in cooperation with Mr. Jishitang and Mr. Niu is also under construction.

In fact, in Lei Shan's plan, it should have been built early, but unfortunately, because after the Lu family's birthday banquet, Duanmu Ying left a note and ran away from home to a foreign country.

The master of Jishitang, as well as the head of the Duanmu family, Duanmu Ying's father was angry, and he couldn't find anyone to be angry, so he attributed all this to Lei Shan, accusing Lei Shan of not putting forward all kinds of ideas in front of Duanmu Ying to worship foreign countries and encourage her to go abroad.

Because of this incident, Lei Shan lay down for no reason, and the negotiation at the beginning was not smooth, but it was later that Lei Shan said something badly, and Mr. Niu persuaded him from the side, and this matter was negotiated.

In addition, it is worth mentioning that during this period of time, the international medical community ushered in a big shock, it turned out that with the help of Lei Shan, the head of the Duanmu family, the master of Liu Tang and Mr. Niu, the three of them, published a paper on penicillin internationally.

Medical newspapers and journals from various countries have rushed to publish this paper, reversing the international understanding of the backwardness of the medical level of the Celestial Empire and that Chinese medicine is an Oriental evil art, and there are even calls that they will be the next Nobel Prize winner in medicine.

For a time, many medical researchers from all over the world came to the Celestial Empire to visit Jishitang and Mr. Niu, just to witness the miraculous effect of penicillin.

Of course, there are more dignitaries and tycoons from all over the world who come to seek medical treatment at great expense, as well as waves of thieves who want to steal penicillin formulas.

There is no shortage of people with a keen sense of smell in all countries in the world, and the value of penicillin is there, and it is understandable that the great powers want it, but in fact, it is also to deal with these open and secret bad things, and the progress of the pharmaceutical factory will be delayed again and again.

And just when Lei Shangou was farming and climbing technology, the famous Northern Expedition in history began.

As a result of the realization of the first Kuomintang-Communist cooperation, the revolutionary power in Guangdong was unified and consolidated, and the workers' and peasants' revolutionary movement in the whole country was unprecedentedly high, which laid the political, economic, military, and mass foundation for the Northern Expedition.

At the beginning, the Northern Expedition was very smooth, and successively knocked out the Sun and Wu families among the three major warlords of Beiyang Zhengaxe, and severely damaged the Zhang family of the Feng family in the northeast.

However, in 1927, due to the blatant betrayal of Mr. Sun's Kuomintang-Communist cooperation policy by a certain bald head and a certain Wang Wang, the Northern Expedition died in the middle of the war.

As these two men colluded with the powerful and inferior gentry, bandits and bullies in various places to massacre the revolutionary masses, the situation in the entire south became a mess, and people came to Leijiabao's sphere of influence every day to seek refuge.

Fortunately, Perak Hall has been operating in Jiangnan for many years, and it has long been deep-rooted, and before that, under Lei Shan's instructions, each force and department has already had its own people, so it will not have much impact on the Lei family, after all, if it is really calculated, the Lei family is the strongest hero, and no one will move unless it is absolutely necessary.

In this troubled world, the four major families of the Inhuman World have died down and acted in a low-key manner, most of the various sects and factions are closed to customers, and they can't come out of the mountain, or they can't withstand the temptation of money and power, and they take the opportunity to expand their power in the fish and meat township.

On this day, Lei Shan watched Ma Ben in the study using the R&D progress report sent by Wang Jiaweixin's yin and yang paper, and the door was knocked open.

Lei Shan looked up and saw a crisp face jumping in from the outside, and jumped onto Lei Shan's desk.

"Boss, someone asked us to do a business with us."

Because of the inheritance of the [Tuanzaburo Raccoon] on the body of the crisp face, there is a talent for doing business, as well as passive skills that can get extra money and the more money you get, the stronger the physical attack power, so after returning from Xiangxi, Lei Shan asked her to help him manage the family's business.

She didn't disappoint Lei Shan, because of the influence of her skills, since she helped manage the business, the Lei family's income has been increasing day by day.

Usually she uses the pseudonym Gan Cuimian, and she shows herself as a fantasy girl outside, and now the entire Perak Hall knows that Lei Shan has two most trusted maids, Lei Chun is like a secretary in the house, responsible for Lei Shan's daily life and going out arrangements, Gan Cuimian is outside, and what she holds in her hand is a money bag.

As for Serkite and Arakni, because of their lack of cultivation, they can't transform into human form, but with Lei Shan's séance, the road ahead has been opened for them, as long as they work hard to cultivate, it will be a matter of time before they become immortals.

Lei Shan picked up the crisp noodles and put them on his thighs, stroking her soft fur while stroking it, and said with a smile: "If you want business, you can do it, whether you want guns or food, as long as you can afford it, then sell it, do you still need to come to me?" ”

simply tilted his head as if he was cute: "This time is different from the small business of those bad guys with 100 guns in the past, this time the people want too many things, I calculate that I can equip a regiment." ”

Lei Shan raised his eyebrows, and suddenly became interested: "Oh? Even in such years, there are not many such businesses, tell me, who is that person's surname, and what is he doing? ”

He simply shook his head and said: "The master asked, but the man didn't say everything, only said that his surname was Wang, boss, you also know that there are many people who do business with us who are unwilling to reveal their identities, but this time the person asked for a lot of things, and the lord and Mrs. are worried that there is fraud in it, so let me ask your opinion." ”

"Which side will it be?"

Lei Shan used his ability to calculate a hexagram, but as a result, a red flash flashed in his consciousness, Lei Shan suddenly understood, nodded and said: "This business is big, it has to be secret, so let's pull one over on the boat on Poyang Lake, make an appointment with that person, and then invite that person to go boating on the lake, I will go and see it myself, if there is really any accident, in Naze country, he can't run." ”

"Okay, I'll arrange it."

After speaking, he jumped off Lei Shan's thigh, and when he landed, he had transformed into a girl again, walked out of the study, and helped Lei Shan take the door.
