Otaku Engineer in Great Tang Dynasty

The reason why Zheng Yinhong was willing to assist Li Zexuan in the construction of a tea garden was that he felt Li Zexuan's sincerity in addition to being driven by interests.

He had contacted many officials in Jiangnan Road and Chang'an City, but Li Zexuan was the first official to talk to him on business as an equal. This moved Zheng Yinhong and at the same time he had a lot of affection for Li Zexuan!

Looking at the convincing attitude of Cao Wendong and others towards Li Zexuan, it is not difficult to understand that he finally made the pledge of allegiance and never betrayal!

If you treat me as a state scholar, I will repay it! Scholar-bureaucrats can die for their confidants, and Zheng Yinhong, who has always kept his promises, can also swear allegiance to Li Zexuan, who treats him as a scholar!

It's true that businessmen pay great attention to profits, but businessmen of this era are also very eager to agree! Li Zexuan's sincerity and Li Zexuan's equal treatment are the most critical factors that impress Zheng Yinhong!

For the allegiance to such a superior, Zheng Yinhong felt that as long as Li Zexuan did not fail in one day, the Zheng family could prosper forever!

At the same time, the news that Li Zexuan possessed a magical tea and a magical tea-making method spread out silently. After all, there is no impermeable wall in the world!

Some civil servants and military generals who were close to Li Zexuan rushed to the Yunshan Mountain to find Li Zexuan for tea!

Fang Xuanling, Changsun Wuji, Qin Qiong, Cheng Yaojin, Li Jing, Li Ji, Yuchi Jingde, etc. are basically three to five companions. They are called visiting Yanhuang Academy, but the real purpose is to drink tea. In the end, Mr. Li Gang saw that his tea was getting less and less, and finally couldn't help but reprimand this group of "not ashamed or ashamed" old guys. The wave of visits by civilian military commanders to Yunshan was only slightly curbed. .

However, Li Zexuan had "heavy bleeding". After tasting the delicacy of Taoist tea, the old guys asked him for tea, but he didn't have much stock, but these old officials treated him well on weekdays. No way, in the end he could only send a small box of tea from door to door!

Well, it’s a small box, a small wooden box specially customized by Li Zexuan. It looks like a box can be drunk ten or so times. Although it is a bit silly, this is the limit he can do. If you want to blame, you can only blame the taste of fairy tea. That's great!

Imagine the tea that even old drunks like Wang Ji and Cheng Yaojin like to drink, can it taste bad?

Poor Wei Zheng is far from Henan Province, otherwise this old sprayer will definitely come to ask for tea!

Li Zexuan, who has little stock, only hopes that Zheng Yinhong can quickly deliver a batch of fried fairy tea to Chang'an!

Yes, he also taught Zheng Yinhong how to make Shenxian tea. Jiangnan Road is nearly a thousand miles away from Chang'an. If fresh tea leaves are transported to Chang'an for processing, the transportation cost will be too great, so Li Zexuan asked Zheng Yinhong to do it. Picking on the spot, frying on the spot, processing, and then shipping the finished product to Chang'an City directly!

…………………………

In the early morning of this day, Li Zexuan had just finished his sword practice and was going to Yanhuang Academy before going out, but at the gate of the courtyard he met someone he couldn't think of!

"Sambo?"

Li Zexuan looked at the unkempt and ragged "beggar" in front of him. Seeing that his face was very familiar, he thought about it seriously, and he suddenly exclaimed!

"Master! The Three Treasures are back! The Three Treasures are finally back! Ooo~!"

Sambo stared at Li Zexuan in a daze. Seeing Li Zexuan recognized him, he immediately knelt on his knees, holding Li Zexuan's thighs, crying and crying.

The sergeants who followed him quickly knelt down, and they were all sent by Li Zexuan to follow the Three Treasures to hunt for mines.

"Get up! Get up quickly! What's the matter with you? Didn't you ask you to go to Shudi to search for mines? How could you be so embarrassed?"

The "miserable" cry of the Sambo shocked the people in the other courtyard. Han Yuxi and Lan'er walked out one after another. The guards Pang Feiji, Liu Feng, Liu Yun and others outside the courtyard also cast their eyes on them. Li Zexuan quickly pulled the Three Treasures from the ground and asked.

It's okay not to ask, he cried even more happily when asked about the Three Treasures. He burst into tears and said, "Master, the Three Treasures are back. The Three Treasures almost can't come back, but the Three Treasures found the vanadium mine for the young master!"

Li Zexuan could feel the sadness in the journey from the words of the Three Treasures, so he asked hurriedly: "Why can't you come back? Is there someone in Shu who embarrass you?"

At this point, Li Zexuan's tone became very unkind. The people he sent out even dared to bully. Isn't this slapped him in the face?

Sambo controlled his emotions a bit and replied: "Master, we found the vanadium mine you mentioned, Master, on a mountain in Changzhou, but was caught by a group of Qiang people. They said we offended their sacred mountain. , We wanted to kill us, and then we declared our identity and saw the leader of the Qiang tribe, who seemed to be Qiao Feng. He asked us why we were digging stones on the mountain, so I told the truth and said it was to help you find the young master. The vanadium mine, but he didn't believe it. He said he had never heard of vanadium mines on the mountain and wanted to let people kill us.

Later, the local county magistrate came in time to save our lives, but the Qiang people said that we were not allowed to take away the ore from the mountain. Then we took advantage of the darkness to go to the mountain and cast a few ore. Who knew that we were killed by the Qiang people. I found that they sent people to chase them all the way. We didn’t get rid of them until we left Yueshang County. But at that time, we lost all the entanglements and fish charms on our bodies, so we could only beg along the way, with a few leaning on the road. A kind-hearted person finally came back~! "

After hearing this, Li Zexuan was silent for a while. He had expected that there might be some twists and turns in this trip, because although the Bashu area was included in the political system of the Central Plains dynasty very early, it was geographically blocked and far away from the political center, plus the Bashu area and the surrounding basins. The area has always been distributed with a large number of ethnic groups such as Di, Qiang, Man, and Lao, making the land of Bashu actually become the "marginal" zone of the dynasty. There are many rich and tribes, and the forces of all parties are also complicated!

So he had explained the Three Treasures before and asked him to try not to conflict with the local forces, but he did not expect that the Three Treasures would still be so miserable, and he almost starved to death on the road!

After a moment of silence, Li Zexuan patted Sambo on the shoulder and said, "Sambo, you have suffered! Don't worry, I will help you get back the grievances you suffered from the Qiang people, Master!"

"Hmm!"

Sambo nodded fiercely, then he scratched his head again, and said, "Young...Master, do you have anything to eat? Sambo is hungry..."

The sergeants behind him also rubbed their stomachs and looked at Li Zexuan with embarrassment.

Li Zexuan quickly ordered: "Xiaohe, hurry! Go and get Sambo and the others some food and drink!"

"Yes! Master~!"

Xiaohe quickly ran into the house.

Li Zexuan said to the Three Treasures: "The Three Treasures, and you all come in, sit and eat slowly, and drink slowly! You have all worked **** this journey!"

"Yes! Master!"

"Yes! Lord Hou!"

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

After a while, Xiaohe and Xiao Xi brought a pot of freshly cooked noodles and a large pot of scallion egg soup, which is commonly known as smoky noodles!

One person served a bowl of noodles and poured a little bit of bashful on it, and a few people from Sambo "huhhuhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh!

"Yeah! Sambo, eat slowly, and no one will grab it with you? Don't choke!"

It was the first time that Lan'er saw people devouring food like this. She was shocked and quickly persuaded her from the sidelines.

"Hmm! Miss Xie cares, Sambo will not choke!"

Sambo eating while returning to Lan'er, he thought in his heart that choking is better than starvation. Such delicious noodles have not been eaten for a long time!

"Lan'er, don't disturb them eating!"

Li Zexuan touched Lan'er's head and said softly.

Although he had a lot of questions to ask the Sambo, he knew that it was not the time to ask questions, and it was serious to let Sambo and the others eat first.

"Oh!"

Lan'er nodded, then stood for a while before going out to play, the little girl is not the kind of idle temper!

After more than a quarter of an hour, the Sanbao finally put down the dishes and chopsticks, and they actually ate a pot of noodles and a pot of sham, just like a starving ghost reborn!

"Hiccup~!"

Sambo and the others got up from the stone bench with full hiccups and bowed towards Li Zexuan:

"Thank you, Master!"

"Thank you Lord Hou!"

Li Zexuan waved his hand and said, "Well, you all go back, wash yourself, rest and rest, and I will reward myself later! The three treasures stay!"

The sergeants hurriedly bowed and said, "Yes! Lord Hou!"

After all, they left.

Li Zexuan looked at the Three Treasures and asked, "Three Treasures, the local Qiang people said that the mine is a sacred mountain. Why is this?"

The Three Treasures thought for a while and replied: "Master, I seem to have heard this from a farmer. That mountain is called Lanjia Volcano. It is said that this mountain can attract soldiers from all over the world. As long as someone passes by with a sword, you will feel it. The sword body seems to have received some kind of traction, and people behind it feel that this mountain has the power of immortals, so people are not allowed to go up the mountain at will!"

"Lanjia Volcano?"

Li Zexuan frowned and suddenly felt that the name was a bit familiar. He quickly searched for relevant information in his mind. After a while, his eyes widened and he said in an incredible way: "You mean that mountain is called Lanjia Volcano? There is another mountain called Jianshan?"

Sambo suddenly stunned and looked at Li Zexuan as if looking at a god: "Master, how do you know that there is a sharp mountain next to it? You are so amazing! There is indeed a sharp mountain next to the Lanjia Volcano, but Sambo hasn't been there yet!"

Li Zexuan was immediately full of excitement, and said: "Great! Great!"

He can now basically conclude that the place where Sanbao went to is the modern Sichuan Panzhihua, and Lanjia Volcano and Jianshan are the largest natural vanadium-titanium magnetite mines in modern China! In the 21st century, except for the United States, which extracts vanadium from potash-vanadium uranium ore, other major vanadium-producing countries all extract vanadium from vanadium-titanium magnetite!

Sambo, they really found a treasure this time!

The local Qiang people mistakenly believed this mountain was a sacred mountain, which is ridiculous in Li Zexuan's view, because the magnetite in the vanadium-titanium magnetite is very magnetic, and the swords that can attract iron have nothing to do with the ethereal things such as divine power. relationship!

"Oh, master, this is the ore we stole from over there. A lot of it was lost while fleeing for our lives. Only two pieces are left!"

Sambo took out two fist-sized black-gray stones from his clothes, handed them to Li Zexuan, and said.

Li Zexuan took the stone, and it looked like iron ore from the outside, but if you carefully observe it, you can find that the color of the stone is slightly lighter than iron ore, and it is slightly lighter than iron ore.

After observing for a long while, Li Zexuan looked at the Three Treasures, and said, "If you are allowed to lead the way and take Young Master me again, do you still know the way?"

Sambo nodded and said: "Recognize! Recognize! Master, don't worry, Sambo definitely knows the way!"

Li Zexuan nodded and said, "Well! Then you go and rest first! This time things are done well, Master I will definitely reward you again!"

The Sambo exposed his "dog-licking nature" at this time, flatteringly said: "Hey! It is the honor of the Sambo to help the young master, and the Sambo dare not reward~!"

Li Zexuan smiled and said, "Oh? In that case, Benhou has fulfilled your wish and won't give you a reward!"

"Hey?"

The smile on Sambo's face stopped abruptly, and replaced with a crying face, he said pitifully: "Master... Sambo just..."

"Haha! It's all right! You kid go back and rest! The reward that should be given to you, Master, I will definitely not miss you a penny!"

Li Zexuan laughed loudly.

Han Yuxi and the others all smiled.

Sambo scratched his head, only then knew that Li Zexuan was teasing him. He was not angry, but bowed and said with a grin, "Sambo, thank you Master!"

Li Zexuan nodded, said to his wife, and went out with vanadium-titanium magnetite.

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

"Mr. Wang, come out with me~!"

When he came to the academy, Li Zexuan came to the office of the Department of Chemistry, found Wang Ji, and whispered.

"Oh! Lord Shan! This old man is here!"

Wang Ji was memorizing the "Regulations on Confidentiality of Yanhuang Academy". Hearing this, he quickly put down the pamphlet and followed Li Zexuan out of the office.

In other words, whether it is a student or a teacher in the academy, whenever they have time, they will take out the "Confidentiality Regulations" issued by the academy and start to memorize it wildly. Take it to heart.

"Shanchang, what is the matter with you looking for Wang?"

Wang Ji followed Li Zexuan to the meeting room and asked eagerly.

He is in a hurry!

Li Zexuan took out the vanadium-titanium magnetite ore and smiled slightly: "Mr. Wang, the person I sent out seems to have found a vanadium ore. The most urgent thing is ~www.ltnovel.com~ We must hurry to verify whether there is vanadium in it~! "

"What? I found a vanadium mine? What are we waiting for, then? Go straight to the workshop!"

When Wang Ji heard this, he was immediately full of surprises. Li Zexuan told him at the beginning that vanadium pentoxide is an important catalyst in the process of producing sulfuric acid. Now that vanadium ore is available, it means that the workshop finally has the conditions for large-scale production. Take the sulfuric acid!
