The earliest sulfuric acid was made from Hao, and it was popular to open alum and fluorine in the old century, or to mix sulfur and saltpeter and burn gold to directly obtain sulfuric acid.

Today's Great Xia Gold manufacturing workers are not much improved, and the Star-Bombarding Warlocks only need a small amount of sulfuric acid. Since the astrosorcerer apprentices were not curious about the bear's ability to resist burning, Jin naturally did not have an urgent need for sulfuric acid.

But Cheng Jinzhou wanted mass production. Simple process production is no longer suitable, not to mention the great waste of raw materials, that is, the slowness of production is already unbearable.

Bai Jing and others are imperceptibly under Cheng Jinzhou. The first step of industrialization has long been set on sulfuric acid, although the gradual lead chamber method was said by Cheng Jinzhou. But they did it entirely on their own. Among the difficulties, Xiao Cheng couldn't help at all.

With his Ph.D. in physics, Kim's understanding of chemistry also ends with what he calls industrial production. In the scientific community of the century, it is also part of the practice.

Yi Su gradually got out of Cheng Jinzhou's back with a flowing tail, and Jin looked around and said:

"The agent is really comfortable. rumble

"Can it be more comfortable than customer service? Boom Cheng Jinzhou glanced at the ring.

"Customer service is like an official you know. They have a lot of power, but there is no way to compare with the businessmen when they are comfortable. rumble

"Chinese-style civil servants bombardment or American-style? Kim Cheng Jinju knows that Isu understands the world before the time travel.

Isu laughed and blasted, "Of course it's American." it

"Poor customer service. Zhicheng Jinzhou shrugged his shoulders and gradually sighed: "It's a pity that we are not big businessmen, otherwise we will abuse this little Buddha to death, so that he can enjoy the past and future lives of the Buddha in the next fight." rumble

"There's a whole planet for you to show off without any interference, and Kim wouldn't be able to help it. Boom Isu shook his head and said, "In the past few years, there have been very few Star Alliance agents who can have such luck as you, so you should cherish it." The current customer service boom is estimated not to let you have any idle days, maybe he has already done it. it

Cheng Jinzhou didn't like the terrifying atmosphere of the former customer service classmate, but he had to admit that the danger was realistic.

"You build your own industry, gradually develop your own industry, find the right product for you, maybe in a few thousand years, you will be part of the Star Alliance, you have a seat in the House of Representatives, you can enjoy the fruits of corruption," said Ni Isu, who didn't know what to think of. The tone became cynical.

Cheng Jinzhou raised his eyebrows, of course he wouldn't answer.

Bai Jing half-pulled Cheng Jinzhou to see his real room. The lead chamber method is simpler, and the boom is to pile sulfur and saltpeter in a container made of lead and burn it with fire around Ni. This is the coal mine, so there is no shortage of fuel, and the raw gold can be bought from other places. Tong guò water transport to get back. Cheng Jinzhou can also find a way to reduce costs.

So the only trouble is the degree of production. The price of lead is not cheap gold, and it is stored in order not to be dissolved by sulfuric acid. Theoretically, it is no problem to change to gold, but if it is turned into copper and iron, it cannot be used.

Cheng Jinzhou knew what was wrong with the lead room method, but Jin still listened carefully to Bai Jing's explanation, and several other star warlocks also looked at him with burning eyes.

At that moment, Cheng Jinzhou remembered the days of substitute teaching at school. Silly freshman. Always look at every person who ascends the podium with magical eyes, if there is a little girl, you will even think that a young doctoral student is a high-level being, maybe in the power of the year can make the faculty worship the kind of people

Xiao Cheng suddenly said with a sense of responsibility: "It's very good, Jin is good, and gradually meets the demand." Pretty good. it

Bai Jing, Liao Yan, Qian Lan and Zhu Jingsheng all jumped up, as if Cheng Jinzhou's admission had given them great encouragement. Until Cheng Jinzhou was sent back to the county, Bai Jing was in a state of elation.

June 5 is the hottest time in Jinchuan State.

The green big-leaved trees all drooped their heads, and Jin didn't dare to show his face to the sun father.

The grasses were a little bolder, hiding in the shadows of the bushes and stealing joy alone. A few rats scurried along the path that people had stepped on, like people climbing mountains, and only then did they stop and stand on the suspended rocks, and they craned their necks to look at the winding convoy on the provincial road, like a miniature version of the sunshine wolf.

The knights of the convoy wore standard armor. There are heart goggles and knee pads, and the chain mail on the shoulders of the gold shoulder is soothingly draped from the shoulder, and the gold is not a little upturned posture, and there is no special treatment of the shoulder, and the handmade suit and the standard suit are often twice the price, and the same is true for the armor.

If there were the sons of the nobles of the past few generations present, he would definitely be able to show that the armor of the knights of the horse team was ordinary and good-fashioned, and the outfits of the leaders were probably worth more than the fiefdoms of the minor nobles. It's a pity that no one cares about the poor Depingbang.

Although no one can look at Lou's own armor. No one can read their thoroughbred either. The knights were still stubbornly fully armed, and Kim only took off his helmet and hung it on the front of the saddle, and Kim held the whip and slammed his waist straight. "Kilometers away from Shaonan, Ni arrived at the city of Shaonan County, Jin announced the congratulatory order of the imperial court, and everyone had a three-day holiday, and Jin played casually. Now I have cheered up, and the leading knight is pure with his legs, controlling the horse with both legs, and slamming his sword with his left hand, and posing as a prince of the turbidity world. It's a pity that he is a little older, and the hurried road for days has made his voice hoarse. If you were younger, the hoarse voice of the knight might be called "Magnetic boom."

"Dun Hu Bang, either send someone to fight the front station first, or inform Cheng Jinzhou" The person who spoke was also sitting on a pure-blooded horse, Ni Dan was wearing a scholar's robe.

What are you doing in such a hurry, gradually, I want to see how he is fishing, how to record De'an's caustic tone, boom is also from the rear, but gradually he is a famous son in the capital, and he is a few gold Mu Yinxing

Scholar.

Ever since he saw Cheng Jinzhou's promotion in the Xia Jing Holy Hall, Mu Yin went home and began to practice hard, constantly trying the star map, and exhausting his time in mathematics and physics. His progress was much bigger than that of his peers, but before he could show off his gold to Cheng Jinzhou, he heard that Cheng Jinzhou was about to become a second-level star warlock.

Mu Yin must see Cheng Jinzhou with his own eyes to make sure that he did not make fake money or anything like that.

The Star Warlock Master wanted to follow the Star Warlock Association and the Imperial Court who sent Bang to congratulate him, and there was no way for Kaneda Shimin to have no choice but to follow Bang, but he became the leader of the celebration team. You can't send three Astral Warlocks to congratulate the second-level Astral Warlocks. Formal celebrations should have formal rules.

Tian Shimin knew that Mu Yin didn't like Cheng Jinzhou, so he sighed and said: "Just two of us, Jin, don't make trouble, Jin, what do you want to do." Then record it and go back and talk about it, don't make a fuss yourself, you know? Dunhu. Let's send someone to the front station. There is no reason to make sense that it seems to be sneaking into the place.

"The safflower boom, you go through it gradually, and Zhou Dunhu ordered it neatly. He is a standard battlefield nobleman, and Ni kills several people every year to maintain his spirit and youth. In the past, he used to go to war. In recent years, prisoners have often been slaughtered, and a few bombs have been made, but in any case, boom, he is one of the few knights in Great Xia who has seen a real battlefield.

Honghua is a young man with a three-flower coat of arms tattooed on his left chest, and he leans over to put on his helmet and urges his horses to run, as if he is going to battle.

The combat effectiveness of the noble knights is not to say boom, but the weapons and equipment and momentum are quite sufficient. In fact, boom in most cases. The combat effectiveness of the noble knights is indeed several times that of ordinary soldiers, boom, they have professional equipment that wastes manpower, Jin has practiced martial arts since he was a child, learned the art of war and basic battlefield knowledge, and Jin grew up listening to the battlefield stories of his parents. They are so bold that they have not only killed chickens and fights, but may also have the experience of whipping servants and even killing passers-by. Gui Mischief, who was cornered, had a stronger sense of warfare than the peasants. Because their lives are more precious, the nobles who have not been cornered have a stronger sense of war than the peasants, because they know how to fight.

Of course, the equipment and combat effectiveness of the nobles are often disproportionate, and a purebred horse can raise the army of the concave people to old age, and the habit of safflower sprinting at will is put in the civilian cavalry, and the bomb is either killed by the commander or tossed to death by the fierce horse under the crotch.

However, the safflower gold, who had just turned the corner, quickly kept rushing back.

Tian Shimin straightened up and gradually knew that something unusual was born.

Finally, there was a young man with a nobleman, and he did not shout Jin Honghua, but until Zhou Dunhu was in front of him, Jin Youbu said: "It seems that the front is the boundary of De'an County."

"Nonsense, at least there is a blade kilometer Zhou Dunhu said that Jin is also a little unsure that it is very common for Jin to lose his way in the march. But it seems to be nonsense to miscalculate the distance bombardment on the provincial roads in the country.

Tian Shimin gently urged the horses to come to Zhou Dunhu's side, Jin looked at his star array and said, "We didn't calculate the wrong distance, we are still thirty kilometers away from De'an."

"So how". Mu Yin said as he flew off the horse, and then he was speechless.

A crowd of knights rushed out of the corner. Then, looking at the scene in front of him, Kim stopped his horse.

The 100-meter-wide canal flows quietly, and two 100-zhang sea boats that can only be seen in the harbor are parked on the edge of the wooden wharf, and countless gold palanquin drivers carry large and small sacks up and down.

On the road, which is wide enough to accommodate four carriages in parallel, merchants come and go one after another. The sturdy mules and horses snorted, and the old ox with broad shoulders lowered his head and dragged the flatbed cart forward with gold.

Facing the knights' left side, there were baked mountains that were higher than the main hall of the palace, and they were bombarded one after another, until there was no end in sight to the corners of the canal. To the right of the knights were mountains of grain, higher than the masts of the ships, one after the other, until they were covered by the mountain.

After a long time, Zhou Dunhu held back a sentence: "It's not the harvest season yet." rumble
