Qin Xuan directly took out the contract talisman from his arms and showed it to Mu Xin: "See, I think you must also have an impact on this kind of thing, we have agreed on a period of 100 years, and after this time expires, the contract will naturally become invalid, and you will be free at that time!"

Mu Xin can only be regarded as a low-level little mother queen, where does she know anything like a contract symbol.

However, although there are similarities between the Zerg and the Cymbal, there are also some differences, the IQ of the Mother Emperor of the Swarm is generally more than twice as high as that of the Mother Mother Emperor of the same level, and the IQ coefficient of the Mother Emperor of the Swarm above level 90 is even higher than that of humans.

Mu Xin has a very high IQ, otherwise she would not be able to become a little mother.

But all beings with IQ are eager to "survive", and Mu Xin is not afraid of death, but as Qin Xuan said, I obviously have hope of living, why do I have to choose death?

100 years is an extremely long time for humans, but for the Mother of the Swarm, it is just a snap of a finger.

The genes of the swarm have been improved and optimized for thousands of years, and they have long been in a perfect state, and they have an endless lifespan, and there is no word aging in the dictionary.

After a short silence, Mu Xin spoke again: "It's not impossible to want this girl to be loyal to you, but 100 years is too long, I can only be loyal to you for 50 years at most, and you have to pay me a high-purity dragon crystal mine as a reward!"

The price offered by Mu Xin is 1 billion units of Longjing Mine per year, and he can take her group of younger brothers to work for Qin Xuan for fifty years.

After the two parties negotiated the terms, they directly entered into a contract.

When Mu Xin swallowed the contract character, there was another set of data in the system database in Qin Xuan's mind: contract value.

There is no upper limit to the contract value, but statistics show that if the contract value is less than 100 points, the probability of betrayal of the contract target will gradually increase.

And Qin Xuan's contract with Mu Xin now has a value of 50 points, which is just above the warning red line.

Qin Xuan thought to himself: I can't bear the child to trap the wolf, anyway, the salary will have to be given sooner or later, it is better to send it to her earlier, and pull up the contract value first, now this contract value is false and has a 50% probability of rebellion at any time, which really makes people feel anxious.

Thinking of this, Qin Xuan directly withdrew 100,000 units of dragon crystal from his Wanjie Taobao account and handed it over to Mu Xin on the spot.

"This is your salary for a year this year, if you need anything in the future, just come to me!" After handing over Long Jing, Qin Xuan didn't forget to say something full of aura.

This made Mu Xin happy: "Great, really good!"

After getting the Longjing ore, Mu Xin danced with amazing joy: "Master, you are really generous, I have no need for anything else, I only need Longjing ore, if you have ore in the future, you will give me all the records!"

"Uh......" Qin Xuan frowned, not that he was frowning at the new high-quality remarks, but that Qin Xuan saw an amazing and familiar scene.

After Mu Xin got the dragon crystal ore, he threw it into his mouth and chewed the ore like a sugar pill.

You must know that this kind of high-purity dragon crystal ore is 47 times harder than steel, and if she throws it directly into her mouth, she is not afraid of breaking her teeth.

When he was in the wild world before, Qin Xuan had also seen the little dragon girl knock the dragon crystal, and later found that the dragon tooth contained a special acid that could corrode and soften the dragon crystal ore, making the texture of the dragon crystal ore extremely crispy and could be chewed by the teeth.

If it's expected, this guy is new......

"Isn't that right?" After scanning the information, Qin Xuan found that the teeth of the Zerg were pure biological metals, and they did not contain corrosive substances.

"Her teeth are hundreds of times tougher than steel!" Seeing the appearance of the new food, Qin Xuan also felt a sense of awe for her, in the end, it was a race that could stand at the top of the universe, and there were treasures all over her body.

After Mu Xin knocked dozens of pounds of dragon crystal in a row, he patted his bulging stomach and muttered, "I finally ate a full meal!"

Qin Xuan asked curiously, "Why do you only eat this?"

Mu Xin glanced at Qin Xuan and retorted: "Can't you see that my stomach is already full, you are really a ...... Not too intelligent humans!"

Originally, it was meant to talk about stupid human beings, but because of the relationship, stupidity became not very smart.

Qin Xuan checked the contract value in the system list and found that the contract value had jumped from the initial 50 points to the current 15,000 points!

Really...... Give her a few sweet dates, and you won't have to worry about her betrayal.

"I think your body is a behemoth, to say the least, it has to weigh tens of thousands of tons, isn't it more efficient for you to directly transform into your body and devour dragon crystals?"

Mu Xin's head shook and the rattle glanced at Qin Xuan's kindness: "Although the dragon crystal ore you gave me is a lot, it is not infinite, if you blindly devour it, sooner or later it will be eaten up!"

"I'd better devour it once an hour, so as to ensure that the resource conversion rate reaches the most perfect state and does not waste resources. ”

This is only one reason, there is another reason: the dragon crystal ore provided by Qin Xuan to Mu Xin belongs to the high-purity dragon crystal ore!

For those races that directly devour the dragon crystal ore to draw energy, they are also very concerned about the "taste".

If there are too many impurities in the ore, it will seriously affect their desire to devour, just like humans have no appetite for food they don't like to eat.

There are very few impurities in the high-purity dragon crystal ore, and they will feel very happy when they devour it.

Of course, Mu Xin is reluctant to eat it all at once, this is her salary for a year, will she eat soil every day after eating it all at once?

There are a lot of dragon crystal veins on Wanghaizhou, but the high-purity veins have basically been swallowed up, and most of the rest are some garbage veins with low content, and the taste is very poor.

"That's right!" After a simple "friendly" exchange, Qin Xuan asked a topic that he was most concerned about: "Little beauty, I'm curious if you can rely on your Protoss bloodline ability to create a group of brave and powerful legions?"

"Of course you can!" replied happily, "I am a great master of the Heshen Clan, I can breed a large number of offspring through birth, these warriors are all my children, they can fight for me!"

Qin Xuan asked curiously, "The 50,000 army you brought before is the offspring you bred, right?"

"No, only 500 of the best warriors are my descendants, and the rest of the five scumbags are the lower creatures we have surrendered!"
