The reason why Zheng Yinhong is willing to fully assist Li Zexuan in building a tea garden is that in addition to being driven by interests, he feels Li Zexuan's sincerity.

He has been in contact with a lot of officials in Jiangnan Province and Chang'an City, but Li Zexuan is the first official to talk to him about business on an equal footing, which makes Zheng Yinhong feel moved at the same time, and also has a lot of good feelings for Li Zexuan!

Looking at Cao Wendong and the others' happy and sincere attitude towards Li Zexuan, it is not difficult to understand that he finally issued the oath of allegiance and never betrayal!

If you treat me as a countryman, I will repay me as a countryman! Scholars 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 national soldier!

It is true that businessmen are profitable, but businessmen in 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!

Loyal to such a superior, Zheng Yinhong felt that as long as Li Zexuan did not fall for a day, the Zheng family would be prosperous forever!

At the same time, the news that Li Zexuan has a magical tea and a set of magical tea brewing methods spread out silently, after all, there is no impermeable wall in the world!

Some Wenchen generals who were close to Li Zexuan were busy and went to Yunshan to find Li Zexuan to taste tea!

Fang Xuanling, eldest grandson Wuji, Qin Qiong, Cheng Yanjin, Li Jing, Li Ji, Wei Chi Jingde, etc., are basically three or five together, and they are called visiting Yanhuang Academy, but the real purpose is to rub tea and drink, and 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 "shameless" old guys, and the wave of Wenchen military generals visiting Yunshan was slightly curbed.

However, Li Zexuan was "bleeding", after tasting the delicious taste of Dao Immortal Tea, the group of old guys came to him to ask for tea, but he didn't have much inventory, but these old ministers treated him well on weekdays, and he couldn't give it to him, so in the end he could only send a small box of tea door to door!

Well, it's a small box, a small wooden box specially customized by Li Zexuan, a box can be drunk about ten times, although it is a little childish, but this is the limit of what he can do, if you want to blame, you can only blame the taste of fairy tea is too good!

Just imagine, even old drunkards like Wang Ji and Cheng Yanjin like to drink tea, can the taste be bad?

Poor Wei Zheng is far away in Henan Province, otherwise this old troll will definitely come to the door to ask for tea!

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

That's right, he also taught Zheng Yinhong the frying method of fairy tea, Jiangnan Province is nearly thousands of miles away from Chang'an, if the fresh tea is transported to Chang'an for processing, the transportation cost is too great, so Li Zexuan let Zheng Yinhong pick on the spot, fry and process it on the spot, and then directly transport the finished product to Chang'an City!

…………………………

In the early morning of this day, Li Zexuan had just finished practicing his sword and was about to go out to Yanhuang Academy, but he met a person at the gate of the courtyard that he couldn't have imagined!

"Three Treasures?"

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

"Young Master! The Three Treasures are back! Sambo is finally back! Whining~! ”

Sanbao looked at Li Zexuan in a daze, and when he saw that Li Zexuan recognized him, he immediately knelt on his knees, hugged Li Zexuan's thighs, and cried and shouted.

Several sergeants who followed behind him also hurriedly knelt down, these people were all sent by Li Zexuan to follow Sanbao to search for mines.

"Get up! Hurry up! What's going on with you guys? Didn't I ask you to go to Shu to look for minerals? How did you get so embarrassed? ”

Sanbao's "miserable" cry alarmed the people in the courtyard, Han Yuxi and Lan'er walked out one after another, and the guards outside the courtyard, Pang Feiji, Liu Feng, Liu Yun and others, also turned their eyes over. Li Zexuan hurriedly dragged Sanbao up from the ground and asked.

It's okay not to ask, but when he asked, Sanbao cried even more happily, he snorted and said with tears: "Young master, Sanbao is back, Sanbao almost can't come back, but Sanbao has found vanadium ore for the young master!" ”

Li Zexuan could feel the sadness of this journey from Sanbao's words, so he hurriedly asked, "Why can't you almost come back?" Could it be that there are people in Shu who make it difficult for you? ”

Speaking of this, Li Zexuan's tone became very unkind, and the people he sent out dared to bully, didn't this slap him in the face?

Sanbao controlled his emotions a little and replied: "Young master, we found the vanadium mine you said on a mountain in Wangzhou, but we were caught by a group of Qiang people, they said that we offended their sacred mountain and wanted to kill us, and then we identified ourselves and met the leader of the Qiang people, it seems that his name is Qian Feng, he asked us why we were digging stones on the sacred mountain, and I told the truth, saying that I helped the young master find vanadium mines, but he didn't believe it, he said that he had never heard of vanadium mines on that mountain, They want people to kill us.

Later, the local county officials came in time, which saved our lives, but the Qiang people said that we were not allowed to take away the ore on the mountain, we then took advantage of the dark to go to the mountain to throw a few pieces of ore, who knew that the Qiang people found, they sent people to chase all the way, until we got rid of them completely out of Yuewang County, but at that time we were all lost, we could only beg along the way, and on the way to rely on the help of a few well-wishers, we finally came back~! ”

Li Zexuan was silent for a while after hearing this, he had expected that this trip might have some twists and turns, because although the Bashu region was included in the political system of the Central Plains Dynasty very early, due to geographical isolation and distance from the political center, and the fact that there have always been a large number of Di, Qiang, barbarian, bureaucratic and other ethnic groups in Bashu and the surrounding areas of the basin, the land of Bashu has actually become the "edge" of the dynasty, with many wealthy clans and tribes, and the forces of all parties are also intricate!

So he had confessed to Sanbao before, asking him not to conflict with the local forces as much as possible, but he didn't expect Sanbao to be so miserable that he almost starved to death on the road!

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

"Uh-huh!"

Sambo nodded violently, then he scratched his head again and said, "Less... Master, do you have anything to eat? Three Treasures Hungry ......."

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

Li Zexuan hurriedly ordered: "Xiaohe, hurry!" Go and get them some food and drink! ”

"Yes! Master~! ”

Xiaohe hurriedly ran into the house with a smoke.

Li Zexuan said to Sanbao: "Sanbao, and you all come in, sit and eat slowly, drink slowly!" You've all worked hard all the way! ”

"Yes! Master! ”

"Yes! Master Hou! ”

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

After a while, Xiaohe and Xiaoxi brought a pot of freshly ordered noodles and a large pot of scallion egg soup, which is commonly known as Zhenzi noodles!

One person served a bowl of noodles and poured a little more noodles on it, and Sanbao and a few people gobbled it up on the stone table in the courtyard!

"Yikes! Sanbao, you eat slowly, and no one will rob you? Don't choke! ”

It was the first time for Lan'er to see someone eating so devouring, she was startled, and hurriedly persuaded her on the side.

"Hmm! Miss Xie cares, Sanbao won't choke! ”

While eating, Sanbao replied to Lan'er's words, and he thought in his heart that choking to death is better than starving to death, such delicious noodles, I haven't eaten them for a long time!

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

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

Although he had a lot of questions to ask the Three Jewels, he knew that now was not the time to ask, and it was only right to let the Three Jewels eat first.

"Oh!"

Lan'er nodded, then stood for a while, and then went out to play, the little girl is not the kind of person who can stay idle!

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

"Hiccup~!"

Sanbao and the others burped, stood up from the stone bench, bowed to Li Zexuan and said:

"Thank you, young master!"

"Thank you, Master Hou!"

Li Zexuan waved his hand and said, "Well, you all go back, wash up, rest and rest, and Benhou will have his own reward later!" Three treasures to stay! ”

The sergeants hurriedly bowed down and said, "Yes!" Master Hou! ”

With that, they departed.

Li Zexuan looked at Sanbao and asked, "Sanbao, the local Qiang people say that the mine is a sacred mountain, why is that?" ”

Sanbao thought for a while and replied: "Young master, I seem to have heard a farmer say this, that mountain is called Lanjia Volcano, it is said that this mountain can attract soldiers from all over the world, as long as someone carries a sword to pass by, they will feel that the sword body seems to be subjected to some kind of traction, and people in the back feel that there is the power of immortals on this mountain, and people are not allowed to go up the mountain at will!" ”

"Lanjia Volcano?"

Li Zexuan frowned, and suddenly felt that the name was somewhat familiar, he quickly searched for relevant information in his mind, and after a while, his eyes widened, and he said incredulously: "You mean that mountain is called Lanjia Volcano?" Is there a mountain next to it called Jianshan? ”

Sanbao was stunned for a moment, looked at Li Zexuan like a god and said, "Young Master, how do you know that there is a sharp mountain next to it?" You're amazing! There is indeed a sharp mountain next to the Nalanjia volcano, but the Three Treasures have not been up yet! ”

Li Zexuan's face was suddenly full of excitement and said, "Great! That's great! ”

He can now basically conclude that the place where Sanbao and they went is the modern Sichuan Panzhihua, and the 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 potassium vanadium uranium ore, other major vanadium-producing countries extract vanadium from vanadium titanomagnetite!

Sanbao: They really found a treasure this time!

And the local Qiang people mistakenly believe that this mountain is a sacred mountain, which is really ridiculous in Li Zexuan's opinion, because the magnetite in vanadium titanium magnetite is strongly magnetic, and the sword that can attract iron has nothing to do with the ethereal things such as divine power!

"Oh, young master, this is the ore we stole from over there, and a lot of it was lost when we were running for our lives, and only these two pieces are left!"

At this time, San Bao took out two fist-sized black and gray stones from his clothes, handed them to Li Zexuan, and said.

Li Zexuan took the stone, judging from the appearance alone, it was similar to iron ore, but if you look carefully, you can find that the color of this stone is slightly lighter than iron ore, and it will be slightly lighter than iron ore.

After observing for a long time, Li Zexuan looked at Sanbao and said, "If you lead the way, take the young master and I will go again, do you still know the road?" ”

Sambo nodded and said, "Recognize!" Recognize! Young master, don't worry, Sanbao definitely knows the way! ”

Li Zexuan nodded and said, "Hmm! Then go down and rest first! This time things are done well, young master, I will definitely reward you heavily! ”

Sambo exposed his "licking dog nature" at this time, and flattered: "Hehe! It is the honor of Sanbao to be able to help the young master, and Sanbao dare not ask for a reward~! ”

Li Zexuan smiled and said, "Oh? In that case, then Benhou will fulfill your wish and will not reward you! ”

"Gah?"

The smile on Sanbao's face suddenly stopped, and he changed to a sad face, and he said pitifully: "Young master... Sambo just ...."

"Haha! Alright, alright! Go back and rest, boy! The reward that should be given to you, young master, I will definitely not give you a penny! ”

Li Zexuan laughed.

Han Yuxi and the others also smiled.

Sanbao scratched his head, only then did he know that Li Zexuan was teasing him, he was not angry, but bowed down with a smile and said, "Sanbao, thank you, young master!" ”

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

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

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

Coming to the academy, Li Zexuan came to the office of the Department of Chemistry, found Wang Ji, and then said in a low voice.

"Oh! Mountain Chief! The old man is coming! ”

Wang Ji was reciting the "Yanhuang Academy Confidentiality Regulations" at this time, and when he heard this, he hurriedly put down the pamphlet and followed Li Zexuan out of the office.

It is said that now 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 them frantically, after all, this week's confidentiality exam is very important to everyone, and no one will not take it to heart.

"Mountain chief, what are you looking for Wang~?"

Wang Ji followed Li Zexuan to the conference room, and hurriedly asked impatiently.

He's in a hurry!

Li Zexuan took out vanadium titanium magnetite ore and said with a slight smile: "Mr. Wang, the people I sent out seem to have found vanadium ore, and it is imperative that we hurry up and verify whether there is vanadium in it~!" ”

"What? Found vanadium ore? So what are we waiting for? Go straight to the workshop! ”

When Wang Ji heard this, his face was full of surprise, Li Zexuan had told him that vanadium pentoxide is an important catalyst necessary for the process of making sulfuric acid, and now there is vanadium ore, which means that the workshop finally has the conditions to produce sulfuric acid on a large scale!
