The list is like this: a set of independent manors, 100 Beihai tribute pearls, silver horse sculptures, 50 million silver coins, a fairy crystal, a purple diamond, a set of glazed tea sets, 100 sets of iron-blooded killing armor, a pound of nine jade fairy tea, and 100 iron sand in Wanghaizhou.

The things in this list, except for the iron sand in Wanghaizhou, other things Qin Xuan has in his hands.

Qin Xuan searched for information about Wanghaizhou iron sand in the Wanjie Taobao network, and found a lot of messy things.

System: According to the data of the Killing World Encyclopedia, the iron sand of Wanghaizhou needed by the Seven Princesses belongs to the feces of the insect swarm!

"Swarm dung?" Qin Xuan suddenly frowned, "What the hell is swarm dung, what does the princess want to do with these filthy things?"

The so-called feces of insect swarms are just some excrement left behind when the cosmic sea insects invaded the primordial universe.

The swarm belongs to the most powerful beast race in the universe, and basically all the beasts will be suppressed by the bloodline when they smell the feces of the swarm, and then flee from the wind.

This characteristic was discovered by the magnates of the imperial royal family, and they would put some Wanghaizhou iron sand in their rooms, so that it could have an excellent insect repellent effect, such as mosquitoes, rats and ants, and other small things, smelling the smell of Wanghaizhou iron sand, they would flee from the wind.

However, Wanghaizhou is still controlled by the beast clan, and it is a place that cannot be affected by the imperial power.

Wanghaizhou iron sand is only something that only a few royal dignitaries have, even the seventh princess does not have.

The invasion of the swarm was originally a universe, and it was already N years ago.

The things left in the primordial universe have long been eroded by time and have lost the essential properties of objects, even in the Wanjie Taobao network, things like insect swarm feces are particularly rare and valuable materials.

The Zerg is a social animal, the little insects follow the activities of the mother, the little mother follows the activities of the big mother, and the big mother also follows the activities of the primeval mother.

Once the ordinary little bugs leave the group, they will soon die and die, unless their mother emperor is captured directly.

The Zerg iron sand in the universe Taobao is calculated according to the "grain", and one iron sand costs 450,000 units to refine crystals.

"Isn't it!" Seeing this exaggerated price, Qin Xuan couldn't help but be speechless, "The price of a swarm of iron sand is so terrifying, isn't there an endless sea of insects in the universe, those top powerhouses in the universe, why don't you just bring back some more iron sand from the outside?"

System: The digestive tract of the swarm has evolved over tens of billions of years to a level of perfection, where they can draw 100% of their energy from their food and excrete very little feces!

"Ordinary small insects may only excrete dozens of iron sand a year, and most of the iron sand is excreted in the insect nest, unless you break the insect nest and can seize a large amount of iron sand, hunting ordinary small insects, you can hardly get these things!"

Qin Xuan secretly said: Then if I can take down a worm nest, won't I soon become a rich man in the universe?

System: Of course, the most valuable thing in the hive is not the iron sand, but the most valuable thing is the cosmic relic!

"All the worm hives are built around the cosmic holy relics, and if you take down a worm nest, you can capture a cosmic holy relic, even the lowest cosmic holy relic, it can also increase the power of the skill by more than 12 times, which is enough to make the entire primordial universe fall into madness!

"Wait?" Qin Xuan asked curiously, "There is a cosmic holy relic in each worm hive, so I want to know how many worm nests there are in the cosmic sea?"

System: 370 years ago, the Supreme Mother of the Mechanical Race once sent a mechanical sentinel to collect intelligence in the Cosmic Sea, and the super electro telescope scanned the cosmic void within a range of 700 billion light-years around the primordial universe, observing about 264 trillion insect nests!

Qin Xuan: Sleep...... Doesn't that mean that the Zerg has 264 trillion cosmic holy relics, and there are only three in the primordial universe, and the insect swarm has come to invade again, what do we do to stop these flood beasts?

System: This question should be asked to the Ancestor Saint Emperor of your human race, if the extraterritorial insect swarm invades, only the Ancestor Saint Emperor, the Night Demon Emperor, and the Supreme Mother Emperor join forces, and the primordial universe can have a glimmer of life, and we, the low-level little ants, can only resign ourselves to fate!

The database shows that there is a large-scale space fleet under the command of the Ancestor Holy Emperor, and this space fleet once broke through the nest of the insect swarm and captured the cosmic holy relic of the insect swarm Annihilation Fate Lock.

The mechanical fleet under the command of the Supreme Mother Emperor has also broken through the nest of the insect swarm and captured the Nine Heavens Supreme Tower, the holy relic of the insect swarm.

The army of ten thousand beasts under the command of the Night Demon Emperor has also broken through the nest of the insect swarm and captured the creature demon night umbrella of the insect swarm.

More than 100 strong people are eligible to teleport directly to the extraterritorial battlefield through the space-time channel to fight against those enemies from outside the territorial.

But in fact, this is just a formality, and even the lowest-level little mother emperor of the extraterritorial zerg is an existence above level 200.

The level of the insect soldier is exactly the same as the level of the mother emperor, why are you level 100 guy running out?

The most fearless mechanical people in the universe will not enter the extraterritorial battlefield until level 500.

With Qin Xuan's current strength, he didn't want to go to the extraterritorial battlefield to collect the swarm iron sand at all, he didn't even have enough entry level, what was the excitement in the past?

Wanghaizhou doesn't need to think about it for the time being, there is a group of bloodthirsty and violent beast clan remnants entrenched in that place, even the reckless tigers are unwilling to provoke them, Qin Xuan is full and has nothing to do, what to provoke them?

System: The Swarm Iron Sand is successfully purchased, consumes 45 million units of crystals, and obtains 100 Swarm Iron Sand.

Qin Xuan's iron sand was purchased from a stall called "Famous Shop", and after the things were bought, the shopkeeper Mingyang applied to add Qin Xuan as a friend as soon as possible.

After accepting his friend, Mingyang immediately sent a message: Brother, the swarm iron sand is still or, I have a lot of goods here!

Qin Xuan replied: 100 is enough, thank you for your kindness.

Mingyang immediately responded: "Then brother, can you borrow your mall to give me a stall to sell goods?"

"Borrow?" Qin Xuan replied rather embarrassedly, "You have learned this word, my mall management fee is paid to the Time and Space Administration Bureau on a daily basis, and you can borrow the things you spend money to buy, it's not appropriate!"

Fame: Well, your store is much more popular than mine, I put the goods on your store to sell, and if you sell something, I'll give you a part of the money as a margin, how about it?

Speaking of Qin Xuan's Wanjie Shopping Plaza, the popularity has skyrocketed during this period of time.

The main reason is that Qin Xuan put a large amount of purple black gold ore up for sale, earning a large amount of cosmic coins, and even gaining a lot of store popularity.
