The negotiated price of a level 10 arrow tower is 10,000 gold coins, and there are 200 arrow towers in the entire Bolivian city, totaling 2 million gold coins!

Bombs and mines were also ordered on a large scale, and Jia Zhengjin was desperately raising the price, negotiating a total of 500,000 gold coins for 1,000 bombs and 1,000 mines. The unit price of each bomb and mine is 250, which is a "compliment" that he secretly sent to all Bolivian officials.

This wave of transactions made a net profit of about 2 million. And on the side of Snow Wind City and North Ibaraki Castle, Grand Duke Farley's father has personally brought people over to contact him, and if he can negotiate it, he can earn at least 4 million more gold coins.

This made Jia Zhengjin more sure of the knowledge he had learned in his previous life. One of the most profitable businesses in the world is to win a big battle, as the so-called cannon goes off for 10,000 taels of gold, and the other is to sell arms, especially when you have monopoly power, you can sell them at a terrible price that exceeds the cost by 100 times, 10000 times or even 10,000 times, and make unexpected profits!

When the business was negotiated, the Bolivian officials and aristocrats immediately pooled together this large sum of money! Although it seemed like a lot, it was easy for each of them to contribute 100,000 yuan. This makes Jia Zhengjin regret that the asking price is too low, maybe he should consider mentioning it several times!

However, doing business is about integrity, so as to maintain future contacts. He has tasted the sweetness of the arms business, and in the future, he will definitely continue to sell these arms to the Duchy of Hells while developing the Holy Dragon City. The more money you make, the more resources you have to develop yourself. Maybe in the end, you can get rid of the drudgery of mining!

In broad daylight, the sun has just risen.

Near Bolivia's tall walls, curious crowds are everywhere. The officials and generals of the city led their troops to keep everyone at bay so that they could not get inside. But in fact, the onlookers were very conscious, and they kept a distance from the soldiers who were guarding them.

Thousands of people were watching, and of course Jia Zhengjin, who built an arrow tower near the city wall.

I saw that he didn't carry anything with him, and he walked to an open space to measure the distance and waved his hand directly, and an arrow tower immediately appeared in the originally empty place. Then he danced his hands around the tower, which grew taller and stronger, and the bolts on it became sharper.

"Wow~~" Whenever Jia Zhengjin built an arrow tower, there was an exclamation from the crowd, all the onlookers couldn't take their eyes off it, and more people gathered from all directions, and even climbed tall buildings, rooftops, and even big trees to find the best onlookers.

"Grandpa, do you see anything?" Lewis was also in the crowd of onlookers, the general in charge of leading the troops to stop the crowd. Seeing Jia Zhengjin's "space magic" with her own eyes, she was actually surprised to the point of numbness!

General Mark carefully watched Jia Zhengjin's every move, and only after a while did he speak faintly: "I can't see it! I really can't see it!" I wondered before, why the city lord of the dignified Holy Dragon City, a strong person who can cooperate with the dragon clan, can't even perceive any magic or sword energy! It turns out that he is a rare space system great mage in the world, and his strength has definitely reached the 9th order! Generally, people who don't feel the fluctuations of magic are either ordinary people who have not learned any magic, or they have strong magical control ability to be completely restrained. I'm afraid he's the latter! The dragon clan plus the space system archmage, it seems that our choice is correct! It's terrible to be the enemy of such a strong man!"

"But grandpa, if he is really a 9th-order space system grand mage, then he shouldn't be afraid of the powerhouses of the four empires! And since the relationship with the dragon clan is so good, and the other party is so provocative, why doesn't he just take the initiative with the dragon clan and go directly to the four empires to make a big fuss? In that case, the four empires can only obediently admit their mistakes and dare not talk about the alliance to slay the dragons, right?" Lewis asked suspiciously, And during the time I went to the Holy Dragon City and came back, I never saw him fight with spatial magic, but I found that sometimes he would fight the enemy in close quarters like a warrior, and sometimes he would become an archer......"

"The strong people who can reach this level, their thoughts are incomprehensible to us!" Mark said to his granddaughter seriously, "Many strong people have very strange personalities, it's not a big deal! It's just that I care a lot, how old is he now! I don't believe that a great mage of the space department can really be just sixteen or seventeen years old as it seems!"

"What if someone is a genius?" Lewis said softly.

"There is no one in the world who can become a ninth-order powerhouse at the age of sixteen or seventeen, and it is also the rarest space system great mage!" General Mark said solemnly, "You must know that in terms of combat power, the space system great mage is far superior to those other single-attribute great mages! Because no matter what forbidden spell you use on him, he can give it back to you by distorting the space! Or transfer the forbidden spell to your city or country, that is quite a terrible thing!" So not to mention the dragon clan, a single space system great mage can go sideways, even if many strong people join forces to deal with him, it may not be effective! Because even if he can't beat him, he can distort the space to let himself escape, who is the big in the world to chase the space system great mage?"

"Is he really that scary?" Lewis was shocked.

"Maybe!" General Mark couldn't be sure, after all, he had only seen information about the space archmage in the history books, and had not seen the real existence. If Lord Kean is really the Grand Magus of the Space Department, I am afraid that his strength will never be weaker than the one recorded in the history books. Because even that one couldn't sit on the dragon as his mount, and the one in front of him did!

If Jia Zhengjin heard the conversation between Mark and Lewis, the grandson, he would probably burst into laughter. He would never have imagined that he would become more and more mysterious in the eyes of others, and even become an invincible super space archmage!

He only has one problem now, and that is that there are too many onlookers!

Although Bolivian soldiers were in charge of maintaining order and keeping all the onlookers out of a dozen meters, the thousands of stares always made him uncomfortable. It's as if I've become a magician who is performing a show, and I'm so nervous that I can't do it for fear that the show will fail.

But this is good for him, at least it can be passed on by word of mouth, so that everyone thinks that Lord Kean of Holy Dragon City is a powerful space archmage! With this title, there may still be some benefits!
