Next week is the university's midterm exams, and the last two changes have not changed in one day, but the update time may be late, forgive me.

Chapter 177 Treasure Digging in District 13 (3) "Brother, those stones you bought... What the hell is the purpose of metal, can it really be sold for money?" Rex asked impatiently after the old woman's vendor left.

Hearing this, Heidi, Melissa and others on the side were also curious, they were all standard magicians, and although they were not ignorant of alchemy, they were not profound.

Liu Zhe smiled and affirmed, and said without concealment: "Of course, according to my estimate, the total value of these five metals is 450,000 gold coins. Liu Zhe naturally wouldn't say that these metals were worth 450,000 system points, so he changed it to gold coins, but in Liu Zhe's heart, 450,000 system points were much more useful than 450,000 gold coins.

"Four, four hundred and fifty thousand!" everyone's eyes widened, they didn't expect to make so much money, you must know that Liu Zhe only spent 135,000 yuan to buy these metals, wouldn't it mean that he made more than 300,000 yuan by buying and selling them!?

Everyone quickly reacted, the old woman of the street vendor is definitely not stupid, since Liu Zhe can make so much money, the key is definitely in the fifth metal that even the old woman doesn't know!

"Brother, what do you think is the use of that big lump of gray metal?" Melissa asked curiously, knowing that Liu Zhe must know the gray metal.

Rex was also curious: "Yes, what does it do, can make you earn so much?" Liu Zhe did not hide it, according to the explanation of the exchange system, and said slowly: "The name of that gray metal is called Mercury, it is a rare metal that can only appear at the bottom of the extremely deep sea, its function is simple, it can increase the speed of magic power, for example, if it is used to make a staff, it can increase the casting speed by 10%, and such a large piece of mercury is enough to make five staffs. "Increase, increase the cast speed by 10%, is that much?" Rex said in amazement, don't underestimate this 10% cast speed, in a battle, this 10% is enough to determine the difference between victory and defeat!

Melissa was puzzled: "I have a question, that mother-in-law said that she once showed the pearl stone to the alchemy master, I think this is not false, if the pearl silver stone really has the effect of increasing the spell casting speed, will an alchemy master not be able to try it?" Hearing this, Liu Zhe was stunned, he hadn't thought about this question, Melissa made sense, if you add the mercury stone, you can increase the spell casting speed, such a simple thing, will an alchemy master not be able to try it?

At the moment when this doubt appeared in Liu Zhe's heart, a system voice suddenly came from Liu Zhe's mind: "Item: Mercury Stone, if you want to explain the item in detail, you need to spend 10 system points. After hearing the system information for a long time, Liu Zhe was stunned at first, and when he reacted, he quietly took out 10 system gold coins from the space ring, and held these 10 system gold coins in his hand and hid them in his pocket, and when Rex and others couldn't see it, Liu Zhe exchanged the 10 system gold coins back for 10 system points.

After having these 10 points, Liu Zhe did not hesitate, and immediately chose to listen to the detailed explanation of the silver stone, only to see that after a system message that deducted 10 points, a string of unfamiliar messages slowly appeared in his mind.

In an instant, Liu Zhe had a deep understanding of the mercury, and immediately answered Melissa's question, "This question is very simple, because the melting point of the mercury is extremely high, ordinary flames cannot forge it at all, and in order to fully exert the effect of the mercury, it must be melted into a liquid form first, didn't the mother-in-law say? Even the green fire can't melt the mercury, and the alchemist estimates that he can't even melt the mercury into a liquid state, so naturally it goes without saying that he will find out its effect." Hearing this, the crowd looked understanding, and they seemed to be able to accept this explanation.

But soon, Melissa raised doubts again, and said, "If even the green fire can't melt the mercury, then what kind of flame can melt it?" At this time, the green fire in the mouths of Liu Zhe and the others, as the name suggests, is a cyan flame, and the flame changes with the temperature, and the color will also change with it, such as the Qingyan Dragon of the ninth-level fire magic, which belongs to the level of the green fire.

Liu Zhe did not hesitate to say, "At least it must be blue fire, but if you use blue fire, it will take a lot of time to melt it. "Blue fire, this is just the minimum condition!?" Rex was stunned, what is blue fire? It is a flame that only an eleventh-level fire magician can release, even if it is Rex, he can only barely release a trace of blue fire now, with his tenth-level strength, its flame is still at the level of green fire.

Alchemists are also magicians, and those who can be called alchemists are all tenth-level existences, and it is likely that this alchemy master happens to be a tenth-level fire magician, so he can't melt mercury.

Hearing Liu Zhe's explanation at this time, Melissa and the others couldn't help but look at him, they never knew that Liu Zhe had such a deep understanding of alchemy.

"Brother Liu is amazing!" Heidi let out a low cry and pulled Ryuzhe's arm, her beautiful eyes as jewel-like as adoration.

Seeing this, Liu Zhewan smiled and gently rubbed Heidi's head.

Melissa said, "Sister really praised you this time, why don't you stop cooperating with Rex and cooperate with your sister?" Hearing this, Rex immediately jumped out and said angrily: "What do you stinky women say, do you understand the rules of first come and then go?" Melissa didn't back down, and then she snickered, and immediately stuck to Liu Zhe's arm, and in an instant, Liu Zhe only felt a softness on his arm, and his arm fell between Melissa's pair of huge shuangfeng.

Melissa exhaled softly in Liu Zhe's ear, and said coquettishly, "Brother, don't worry about Rex, if you cooperate with your sister, your sister will do everything for you?" "What, anything?" Seeing Melissa's coquettish appearance, Rex swallowed a touch of saliva, and then he immediately changed his words: "What a chance, brother, you don't care about me, you can make more money if you don't have money, and if you miss this great opportunity today, you won't have it!" As he spoke, Rex's expression froze, and at this time he only felt that his left hand was cold, and at this time he realized that he was still holding hands with Charlotte, and at this time, the palm he was holding with Charlotte had completely frozen into ice, and Charlotte was looking at him with a cold face.

Seeing Melissa's actions, Heidi's small face bulged wide, and under the urging of an unfamiliar emotion, she suddenly hugged Liu Zhe's other arm, and said with a red face: "Hai, Heidi can also do anything for Brother Liu!" Another soft touch came, compared with Melissa, although Heidi has not yet matured, but it also has a lot of weight, and it is definitely not a degree that can be ignored.

At this moment, Liu Zhe suddenly became a left and right hug, don't forget that they are now on the street, all of a sudden, the surrounding passers-by came with a jealous look, they really don't understand that with Liu Zhe's goods, what can make two beauties embrace?

"Ahem... Melissa, don't make a fuss, it's still on the street here, and I've already talked to Rex about the cooperation, and I have to abide by what I say. Liu Zhe coughed in embarrassment, and as he spoke, he slowly pulled his arm out of Melissa's arms.

But at this moment, Liu Zhe's other arm did not break free from Heidi's arms, but let Heidi hold him.

Melissa was not angry when she was rejected, and said with a smile: "Hehe, my sister is just joking, but brother, you are really partial!" Saying that, Melissa glanced at Heidi enviously.

Liu Zhe said seriously: "Men and women don't kiss, it doesn't matter if Heidi is my sister, Melissa you can't, it will ruin your reputation." "What kind of reputation, my sister is not going to marry you?" Melissa said badly.

Hearing this, the corners of Liu Zhe's mouth twitched, and he politely refused, "This ...... Let's talk about it later. Seeing Liu Zhe's funny reaction, Melissa accepted it when she saw it, and smiled triumphantly, but did not continue to tease Liu Zhe, but at this time Melissa looked at the "two pairs" around her with some envy, Heidi hugged Liu Zhe, Charlotte and Rex also held hands, as if she was the only one who had no companion......

"Don't overthink it. Melissa quickly shook the thought away, no longer thinking.

※※※※※※※※※ was laughing and walking, and unconsciously, Liu Zhe and the others had been walking around the thirteenth district for a long time, and it was already dusk and approaching night.

It's a pity that since the mercury stone, Liu Zhe has not bought anything again, it seems that the treasure is not so easy to find, and it can be said that it is extremely lucky to be able to find such a treasure as the silver stone at the beginning.

"It's getting late, aren't we almost going back? Melissa reminded that it was already dusk, and if they had walked a long way back to the Golden Diamond Hotel, it would probably be night.

As it got late, many stalls in the 13th district began to put away their goods, seeing this, Liu Zhe also said, "That's it for today, there will be a game tomorrow, let's go back and rest quickly." "Okay. Rex's tone was a little reluctant, but considering that Mercury had already made a lot of money, he didn't think much about it at this time.

With that, everyone turned around and was ready to return to the Golden Diamond Hotel.

However, at this time, Liu Zhe suddenly shouted to everyone, saying, "Wait first!" Hearing Liu Zhe's sudden voice, everyone was stunned at first, and then they looked at Liu Zhe in confusion, and at this time they turned their heads to see where there was still Liu Zhe's shadow at this time, only to see that Liu Zhe and Heidi had run to a stall a few meters away.

Seeing this, Rex showed a happy expression, and immediately followed briskly.
