It was the logistics staff of the Norn Guild who contacted Lu Chen, and according to Lu Chen's guess, Norn should have handed over the harvested recipes directly to the logistics department after he returned. They may have made some Mechanical Lube, but it didn't work until the level 80 quest and the Mechanical Age version arrived.

The logistics staff knocked on the side several times, wanting to learn the role of [mechanical lubricating oil] from Lu Chen's mouth. Lu Chen only said that it was a task to use, and it needed a lot of money.

That person wanted to sell [Mechanical Lubricant] directly, but of course Lu Chen refused, his idea was to get all the formulas in the hands of the Norn Guild. In the end, the man couldn't grind Lu Chen, so he sold 10 formulas to Lu Chen with 50 copper.

Lu Chen returned to the Moonlight Kingdom satisfied, and threw the seven or eight hundred formulas and tens of thousands of units of the three materials in his hand to the person in charge of the Glory Fortress Comprehensive Workshop, and asked him to arrange a group of more reliable people to produce this [mechanical lubricating oil].

After two days, he will get all the recipes of the Norn Guild and expand the production.

The next day, Lu Chen spent a lot of money to buy two [Third-Order Frozen Magic Scrolls], and then arranged for hundreds of guards of immortal love, hundreds of thieves from Lin Xiaowu's demon thief group, and absolute henchmen from other places, and sent them all into the underground world.

But after all, the paper can't contain the fire, and the news of the underworld leaks out that afternoon, and the guards of the Immortal Love come back to report that there are signs of others coming to explore near the entrance.

"Transfer all the God Generals over and clear the field to brush [Desulfurization Gypsum]!" Lu Chen was silent for a while, but he didn't expect that he couldn't prevent it despite all the precautions, which made him very discouraged. The Norn Guild casually has more than 1,000 reliable henchmen, and when he dreams of returning to the Tang Dynasty, there are 80,000 absolutely reliable troops, but he leaked the news when he mobilized 600 people.

Since the news was leaked, Lu Chen no longer hid it, he informed [Norn] out of politeness, and then used the remaining [Third-Order Frozen Magic Scroll], transferred two thousand elites into the underground world and began to brush them up.

Then Lu Chen contacted the logistics staff of the Norn Guild again, and told him that what he was doing was a mission, and there was a follow-up, and this time he needed to buy 50 formulas, and asked him if he could get a discount.

The horizontal and vertical underground world is still producing this kind of formula, and it has not yet been found to have any effect on this thing, so the logistics staff felt that this formula should not be very valuable, so they sold the formula to Lu Chen at a nine-percent discount.

The next day, Lu Chen bought 100 formulas again under the same pretext, and on the third day, he wanted to buy 500 formulas, but the man was already suspicious and asked for the price to be doubled. Lu Chen felt that this was a temptation, if Lu Chen agreed, that person would definitely feel that this formula was still useful, so Lu Chen refused to die, and finally succeeded in buying it.

At this time, Lu Chen no longer hid it, and let the Glory Fortress Comprehensive Workshop start to produce [mechanical lubricants] at full capacity. In two days, the true face of the level 80 dungeon will appear in front of everyone, and in the face of a large number of mechanical monsters, Norn will definitely think of such a thing as [mechanical lubricant]!

Therefore, Lu Chen made the first move, and while producing with all his might, he also used ten golden warships as collateral to borrow 50,000 gold coins from Menghui Tang Dynasty, promising to return them within a month. Then Lü Chen used the money to buy three materials in the Assyrian Empire.

The three materials of the Ram Kingdom and the Thunder Empire's [Mechanical Lubricants] have long been acquired by Noya and them. Several other countries have also been bought by almost half of the game merchants they work with. Only the Assyrian Empire, because the Norn Guild completely controlled the empire, in order not to attract the attention of the outside world, the market here has not been moved.

And recently, Noya, Duan Wufeng, and the Xiangnan Chamber of Commerce Alliance have gradually become a little less confident, because this investment has not returned for more than two months, and Lu Chen has guarded the reason why these materials will appreciate to the death, and they are slowly a little weak-hearted, so no one in the market of the Assyrian Empire moves.

After the news of the underworld leaked, Noya and Xuan Wufeng obviously received the news, but in order to cover up the matter of their placement in the wolf clan, they simply endured it. It wasn't until Lu Chen ordered the large-scale production of [mechanical lubricants] that they couldn't help but find the door.

"President Poison Wolf, it's so big." Noya sneered and looked at Lu Chen, despising Lu Chen's practice of eating alone. However, she didn't stand to blame anything, after all, the Snow God Guild and the wolf clan did not sign any alliance agreement.

"Hehe... You're all in the right place. Lu Chen also stared at Nuoya and Xuan Wufeng with an unkind face, grandma's, they planted a traitor under him, and they even had the face to ask the teacher for the crime?

"Let's get it straight. You haven't revealed the exact news to us before, and now you have smashed tens of thousands of gold coins at once, and eaten the three materials of the [Paraffin] of the Assyrian Empire, are these materials about to appreciate? ”

After all, Noya is familiar with Lu Chen, and there is no need to hide it.

"That's right! And it's skyrocketing! According to my estimates, within a month, the value of the two samples of [paraffin] and [desulfurization gypsum] will appreciate by about ten times, and the value of [tung oil] will also increase by five or six times.

What do you think? Isn't it worth waiting for two or three months to make you more than seven times your profit at once? Lu Chen's face also eased, thinking of the gold and silver mountains that were about to arrive, he also felt comfortable physically and mentally.

When the time comes, how about buying Qingyun Pavilion with money? Well... On the side of the Liangshan Brotherhood, they will also invest a sum of money to completely dig out their middle and high-level leaders, so that they can also taste the power of the money offensive!

Lu Chen imagined the future, but Noah and Xuan Wufeng were stunned. Originally, they thought that it would be good to have two or three times the return on this investment, and they didn't dare to think of higher profits at all.

But now Lu Chen actually said that there was seven times the profit! What is this concept? Noya and Xuan Wufeng each invested sixty or seventy thousand gold coins in it, and this time it was three or four hundred thousand?

The heartbeat of the two of them suddenly increased irrepressibly, but they couldn't believe it, "Really? ”

"Of course. If you don't believe me, you can sell me your materials now for three times the purchase price, but the payment will be settled in a month. Lu Chen looked at them with a smile, and his expression was as tempting as he could.

In fact, he is quite righteous, otherwise as long as he pretends to scare them, they will definitely transfer all the materials in his hand to him at this price.

Noah and Broken Breeze were also relieved when they heard this, and then they remembered the other purpose of this place - the underworld!

"That recipe was farmed from the underworld, right? It's not a good habit to eat alone, at the beginning, we..."Noya was trying to blackmail Entu to repay Lu Chen, and used the fact that they helped Lu Chen deal with the crusade alliance to make Lu Chen relieved, but Lu Chen waved his hand.

"There's the Norn Guild down there. As I agreed with Norn, neither of us could let anyone into the Underworld for at least one week. ”

Lu Chen said and showed a contract, and obtained the understanding of Noah and Xuan Wufeng. Anyway, the skyrocketing price of materials is enough for them to make a lot of money, and the profit of the formula is embarrassing to grab it from Lu Chen again.
