Lu Zhe thought that it would take a while for someone to come to him.

The reason is simple: the inefficiency of the bureaucratic system and the lengthy process of approval, escalation and evaluation are the same in ancient and modern times.

So, on the second day after arriving in Chang'an, Lu Zhe rode a little green donkey, took Ah Fei and Yun Needle, and let the coachman of the princess's mansion, a big man named Li Zhong, as a guide, and took a good look at this miracle city.

After all, having money can be fun anywhere. This is also the same in ancient and modern times.

The morning bell of the wild goose pagoda, the smoke of the grass hall, the new green of the Qujiang River, the Jiajia soup cake in the east market, the roasted mutton of the Hu people in the west market, and even the fragrant Hu Xuan dance of the Persian Ji and the juggling tricks of the poisonous people, Lu Zhe has felt the elegance of Chang'an in the past few days.

Of course, he is not just touring, he is also very busy. This is Chang'an, where the top group of people in the world live, and some of his previous plans and ideas can be tried to be realized.

He made a pot.

The iron pot is a thing, as a glutton, Lu Zhe has wanted to have a bite for a long time. However, limited by the level of blacksmiths in Rock Town, what they created was a thick cast iron pot, the thickness was a little uneven, so that the stone pot still used in the natural home is still used, although the heat preservation is good, but the heat conduction is still very slow.

Now it's okay, on the first day of Lu Zhe's arrival in Chang'an, with the power of Rencheng Wangfu and his golden cakes, Lu Zhe found a good blacksmith and created a very good iron pot.

Although Pei Qingnu still has a little complaint about the master and servant eating at the same table, but after tasting the stir-fried dishes made by Lu Zhe, Pei Qingnu also has to admit that this immortal disciple really has a hand, and such a delicacy is a person in the Taiji Palace, and he has never eaten it.

Feifei and Yun Needle were also eye-opening, and the mysterious little master opposite them became more and more unable to see clearly.

Stir-fry is so endearing, that every night, Feifei and Yun Zhen will look forward to their little Langjun returning happily and returning to the palace for dinner, Pei Qingnu said that this is not in accordance with the etiquette, but every time Yun Zhen came to please, she happily went. And every time it violates the rule that ladies should eat less, every time several people eat cleanly.

Of course, Lu Zhe didn't make an iron pot entirely for eating, after testing the effect of the iron pot, Lu Zhe ordered several cauldrons, and let the blacksmith finish beating it and send it to Panshi Town.

Since the material civilization has been built, the spiritual civilization cannot be left behind. Lu Zhe went to a famous bookstore in Chang'an in the past few days - Tianyifang (Tianyifang, the ancient bookstore was afraid of fire, many of them were called this name) A whole car of books was moved to the palace, except for his own reading, the rest were sent to Chenzhou.

Although Datang's books are very expensive, no matter how poor you are, you can't be poor in education, right? Lu Zhe has been in the city for the past few days

The third thing Lu Zhe did was to put a farrier on his little green donkey.

Don't think that the Ann Horseshoe is very simple, although this thing seems to be not difficult and can be seen through at a glance, but in ancient times, it also took some effort.

It's easy to build iron bars and drill holes the size of a donkey's hooves, but here's the problem.

There were no iron nails in ancient times!

Don't look at the iron nail is very simple, China only has this thing in modern times, when the Hanyang Iron Works produced it, the common people called foreign nails.

So, with the intervention of Lu Zhe, an "immortal disciple", what would have appeared after a thousand years appeared in Datang at this moment.

The blacksmith's skills were very good, Lu Zhe described it a little, and made what Lu Zhe needed, and then with the help of Ah Fei, he successfully helped the little green donkey to load the farrier.

At the beginning, the little green donkey was still a little uncomfortable with his new shoes, and he was always stumbling, and after a long time, the sound of donkey hooves began to sound in Rencheng Wangfu.

Regarding the matter of the donkey's hoof, Lu Zhe, who knew that this might change the pattern of this world, strictly forbade Ah Fei to say it, and prepared to give it up when he met the magnates of Chang'an, or even asked to see Li Shimin.

Pei Qingnu, who originally regarded herself as Lu Zhe's maid, could have discovered the abnormality of Lu Zhe's little green donkey, but she did not find this invention that might change the situation of the war.

Because Pei Qingnu is too busy.

Because although the Rencheng Wangfu is in Chang'an, the Rencheng King has not been in the capital for a long time, and only some guards and an old housekeeper are left here. Therefore, the affairs of the house, the old housekeeper must discuss everything with Pei Qingnu.

And why did Princess Rencheng Li Xuejiao send the female officials around her to Lu Zhe's side, mainly because she was worried that the little collaborator she was optimistic about did not understand the Chang'an ecosystem, and needed a person who knew this well to help take care of it, Pei Qingnu, who was born in a family, was naturally an excellent candidate, and Princess Rencheng also needed a trustworthy person to watch Lu Zhe, plus Pei Qingnu's swordsmanship was amazing, and he could also protect Lu Zhe, who was not young and powerless, so Pei Qingnu was the confidant of Princess Rencheng and temporarily acted as Lu Zhe's maid.

Of course, the reason why Princess Rencheng was able to send her henchmen and female officials shows that she attaches great importance to Lu Zhe, which can be regarded as an extremely heavy investment.

During this time, Pei Qingnu's main job was to package Lu Zhe and let him successfully integrate into the circle of the scholars. On the second day after arriving in Chang'an, Pei Qingnu called a tailor and carefully measured Lu Zhe's height and size, and made dozens of sets of clothes from winter to summer, including regular clothes, hunting clothes, dresses and so on. and personally taught Lu Zhe the etiquette of some scholars, which is completely the style of an etiquette teacher.

In fact, the scholars of Chang'an, both in terms of etiquette and clothing, are also quite complicated. Not to mention the things involved in the six arts of the gentleman, such as eating, saluting, drinking tea, hunting, music, archery, etc., it is also very troublesome to travel daily, for example, Lu Zhe needs a variety of jewel-inlaid heads to match various colors of round-necked robes, and with them, there are boots, jade pendants, sachets, fans, waist knives, saddles, bronzing nouns, famous thorn boxes made of good sandalwood, etc., in addition to the clothes and accessories of servants and guards, which are also very important, a large set of everything.

It's just that this Xiao Langjun is very playful on weekdays, he goes out to play every day, and Pei Qingnu, who has experienced this way and knows this Xiao Langjun's methods and personality, naturally does not dare to stop it, so he can only teach Lu Zhe carefully after dinner every day.

After seeing Lu Zhe's methods of destroying people at every turn, as well as all kinds of miracles along the way, Pei Qingnu had long been convinced of his identity as an immortal disciple, but he just sighed that when the immortals taught him skills, he didn't teach his mind well, and taught such a little gentleman who played the world and didn't like the rules of the world.

Therefore, Pei Qingnu had to deal with the arrival of the Rencheng Palace's mansion during the day and Lu Zhe and Feifeiyun Needle, and at night he had to teach Lu Zhe etiquette, so he was naturally very busy.

Lu Zhe and Pei Qingnu are so busy, Feifei, who is the security captain of the Hundred Flowers Sect (Lu Zhefeng), and Yun Needle, the deacon of the outer gate of the Hundred Flowers Sect, naturally can't be idle. In addition to going out with Lu Zhe every day and helping Lu Zhe deal with chores (helping to buy iron pots, books and other materials), they were also called by the old housekeeper to teach etiquette about the etiquette of servants.

Of course, the maids and guards around the scholars also have etiquette requirements, and there are more things that need to be paid attention to, after all, if the master is rude, the other party may not mind, if the entourage is rude, it is extremely humiliating and rarely forgiven.

Feifei sold his life to Lu Zhe, so naturally he had nothing to do, but Yun Needle didn't have any objections at all, which made Lu Zhe secretly vigilant in his heart, and decided to take a good look at it, after all, his Datang version of the "Three Corpse Brain Divine Pill" was actually a pill for pregnant women to replenish qi, and if it was found that it was not poison, maybe he would be in danger.

At the same time, Lu Zhe also gave Yun Zhen a task, that is, to take the cotton peaches that Lu Zhe bought at a great price and let her find a way to weave them into cloth.

Cotton cloth and cotton, naturally Lu Zhe lit up the Datang science and technology tree, an important plan to improve people's livelihood, he even bought a lot of cotton peach seeds, let people send them to Chenzhou for planting, and told the people of the Mu family to look for old farmers, must plant them in a large area.

So, in the busyness of everyone, time passed in a hurry, and in a blink of an eye, Lu Zhe and the others arrived in Chang'an, and it was already the fifth day.

"Lang Jun, Daochang Sun is visiting." It was Yun Zhen who spoke, and at this time she was wearing a maid's dress made of white silk, and she saluted Lu Zhe respectfully, which was already very decent.

"In that case, please hurry." Lu Zhe waved his hand slightly, Yun Needle said a promise, saluted, and stepped back in small steps.

Migrate qi and nourish the body. The crazy etiquette training during this period of time not only made Lu Zhe finally look like an ordinary scholar, but the cloud needle was perfectly integrated into the identity of the maid. This made Lu Zhe not only a little unbearable, but he was a good female technician, but he was transformed into a maid, and the idea of feudalism was really deadly.

He didn't want to treat her as a maid, but thinking of what she did to that baby, Lu Zhe had no choice but to harden his heart and become a scholar who enslaved others.

However, this cloud is true love for textile embroidery, through this period of observation, Lu Zhe found that the cloud is extremely serious about the task he gave her, not out of the consciousness of the maid, but the task of true love, as if the technicians of later generations have encountered a new problem, not only the excellent completion of the maid's character during the day, but also does not rest when it is dark, and lights the lamp to study how to spin cotton peach into cloth.

Perhaps, she also had no intention of doing evil, but she had received that kind of education since she was a child, thinking of the vice of Tiansunmen, Lu Zhe was determined and remembered the matter of the cloud needle.

Through Pei Qingnu's side knocks, Ah Fei's secret monitoring returns, and Sun Simiao's views on Yun Needle along the way, Lu Zhe found that in fact, Yun Needle's nature is not bad, and her heart is also very painful and entangled, not so much that she was forced to be poisoned by Lu Zhe, but that because of the guilt and pain in her heart for killing her own child, she agreed to become Lu Zhe's maid to punish herself.

Therefore, she chose to leave the Yu family and join the Hundred Flowers Sect to become a deacon of the outer sect, although there is an element of force, but it can be regarded as a denial of her own sect in her heart.

Whether it is to switch to the Hundred Flowers Sect, become Lu Zhe's maid, or devote herself to the study of cotton cloth, it may be a way for her to transfer her pain.

There was also an anecdote during the period, that is, when Lu Zhe accepted her, he asked her name, and the needle girl admitted that her surname was Yun, so Lu Zhe's spoof came up again, and she was about to give her a new name.

His surname remains the same, and his name is 纨嘉. The silk, the fine silk, the Jia, the beautiful, at that time, everyone thought it was a very beautiful name.

But I don't know why, the needle girl, who has always been in a deferential attitude towards Lu Zhe, expressed a considerable degree of resistance to the name Yun Yunjia, and immediately knelt on the ground, saying that she was willing to take the name of the needle and was unwilling to change her name.

Lu Zhe originally wanted to spoof himself, wanting to commemorate his identity as a barrage god and cloud player in later generations. As a result, seeing that her intuition was terrifying, she stopped insisting.

So, the needle girl changed her name to Yun Needle, became the outer deacon of the Hundred Flowers Sect, and now temporarily takes the position of Lu Zhe's maid.

I didn't expect that unconsciously, the people around me in the mountain gate were all perfectly integrated into the world, and I thought that these people in the mountain gate had lived in the mountains for a long time, and they would be very uncomfortable in Chang'an, but I didn't expect that the most uncomfortable thing was themselves.

And what made Lu Zhe a little relieved was that his Hundred Flowers Sect was no longer only the empty sect master and Yun Niang, the empty deputy sect master, but also a security captain and an outer deacon.

The team began to be built, and it got better, Lu Zhe sighed secretly, while looking at Ah Fei, who was dressed in a brand-new blue dress next to him, standing like a javelin, and looking good at eyebrows, and the needle girl who was gorgeously dressed and not at all as weak and sad as that day, and then looked down at his brocade clothes and jade sachets, and the small building he wore on his waist listened to the spring rain overnight, Lu Zhe couldn't remember what he looked like when he was wearing a lot of hay to keep out the cold and wear a rotten fur when the sun rose on the mountain.

Luckily, you haven't changed. Looking at Sun Yaowang, who was still dressed in shabby Taoist clothes and a little boy carrying a medicine box on his back, walked far away, his kind and gentle smiling face, and the temperament of the fairy wind and bones, just like the first time they met at the gate of Wuzhuang Guan that day, I don't know why, Lu Zhe suddenly sighed.

"I've seen the Taoist." Before Sun Simiao approached, Lu Zhe immediately bowed from a distance.

"I haven't seen you for many days, Xiaoyou is becoming more and more handsome, and the predecessor Yunzhi Lanbaoshu is honest and honest." Still with a gentle smile, Sun Simiao helped Lu Zhe up like a generous elder.

"The Taoist is overrated, and the kid is terrified." Lu Zhe didn't call himself a philosopher, but returned the gift according to the general style of a scholar boy.

Hehe, the two looked at each other and smiled, everything was silent.

After the salute is over, enter the room to speak.

As Lu Zhe expected, Sun Simiao came to look for him this time, because someone wanted to see him. During this time, he was also mentally prepared for this, and made a rough guess about the person who wanted to see him.

He has been waiting for this day for a long time, and has made a lot of preparations for this, in order to be able to meet the core figures of Datang, so as to realize his plan to light up the Datang technology tree as soon as possible.

To Lu Zhe's surprise, the people who wanted to see him this time were not in Lu Zhe's speculation. Neither the Pei family, the Cui family, the Yang family, nor the eldest grandson's family, nor the imperial doctor in the palace. It's a name he didn't even think about.

It turned out to be Wu Guogong who wanted to see him - Wei Chi Jingde!
