PS: Update later

In the past six months, he has sold medicine once a month, and his net worth has doubled, and the accumulated spirit crystals at this moment have exceeded 10 million, which is comparable to the net worth of a king.

But he also sold too many medicines, which has affected the price of medicines in the temporary bazaar of the Qingjiao tribe, causing the purchase price to drop as well.

In the past, there were no alchemists to provide medicines in this temporary market, and the major trading houses were all transferred from the headquarters, so the cost was higher.

As soon as Xiao Mu came, the cost decreased, the supply increased a lot, and the major merchants began to reduce the price appropriately in order to attract customers, which made him helpless.

After all, this is a market behavior, he is a supplier, and as the level increases, there are too many drugs sold, and thousands of drugs can be sold every month, and this market cannot digest it in a short time.

Just when Xiao Mu was thinking about whether to find a new market to develop sales channels, there was a big change in the information brought back by one of the chess pieces.

A city on Earth has been destroyed by aliens, with heavy casualties!

He was very surprised when he received the news, why the alien race would destroy a city, it was obviously a great contradiction to do so.

"Gotta see what's going on."

He hurriedly opened the detailed information, only to know that the destruction of the city originated from a inheritance exercise.

This technique was obtained privately and was not shared, but the cultivator's strength was quite strong, so he was targeted by the alien race and wanted to seize it.

Originally, the owner of this exercise did not want to hide it, but was just ready to exchange the exercise for some more benefits.

However, there was a problem in the exchange, and it turned into a fight, and the man killed the clansmen of the Blood-Eyed White Ape Clan, which annoyed the great commander of his clan, and in a fit of rage, he directly destroyed a city.

Of course, this battle human beings are not soft persimmons kneaded at will, all kinds of technological weapons broke out, killing some fourth-order alien races, and finally seeing the city ruined, they used forbidden weapons to kill many fifth-order alien races.

The whole incident was a lose-lose situation for both sides, with the most human casualties.

He looked at the data, originally there were more than 500,000 people in this city, but under the First World War, more than 200,000 died, and the rest would have died even more if they hadn't hid in the dungeon in time.

"This is a problem."

Xiao Mu had a headache, this war was not a good sign.

Of course, it can let the alien race know that humans are not random to slaughter, but it also allows the alien race to perceive the true ability of human beings.

That's a technological weapon!

Nuclear weapons, in particular, are completely enough to threaten alien races, but they also kill 1,000 enemies and lose 800 themselves, and once nuclear weapons are used, the soil will be polluted, and cities will be flattened, and there will be no chance to rebuild.

For example, the city that used nuclear weapons this time can only hide in the dungeon.

Outside, the residual radiation can easily kill ordinary people, even ordinary warriors can't bear it.

Other people want to rescue, it is also very difficult, after all, a radius of dozens of kilometers is a radiation area, the safest must be to dig tunnels, but for a city with a population of hundreds of thousands, a tunnel is completely insufficient.

Unable to quickly obtain resources from the outside world, it is very difficult for the city to recover, let alone continue to develop, and it has basically been abandoned by the times.

Xiao Mu sighed secretly, this city belongs to one of the great cities of the human race, second only to the main city, and being destroyed at this moment will have a great impact on the entire human race.

"I have to go back, if there are similar accidents, we must come forward to stop them, we can't consume them like this with other races, they just die a few fifth-order and some fourth-order, but we have to die hundreds of thousands of people, the city is ruined, the cost is too great, and we can't afford to fight at all."

A solemn look appeared in Xiao Mu's eyes, and after browsing the other news, he found that the alien race as a whole was a lot more aggressive towards humans.

"If there is no fighting, do you put your mind on the human race, you have to find something for them to do."

Muttering, Xiao Mu thought about how to deal with the new situation.

It is impossible to confront the aliens, and this destroyed city is a proof that the hard city is just more or less destroyed cities and the number of humans killed.

With a decision, he didn't go back immediately, but took the spirit crystal and purchased it again, buying a large number of resources that he might use.

For him, the spirit crystal doesn't need much, just a little enough, and the resources of the Wild Land are very important, once he goes back, it is very difficult to obtain.

"When the next time the pieces return, take the opportunity to go back."

Xiao Mu prepared everything and told several trading houses that he was going to retreat to improve his strength, and he would not sell medicine for a short time.

This made the major commercial houses think that Xiao Mu was not satisfied with the recent reduction in the purchase price, and patiently wanted to explain, Xiao Mu was speechless, and said a few more words before reassuring the other party, knowing that he really wanted to retreat to improve his strength.

After dealing with this matter, Xiao Mu waited, in order to avoid the clones being destroyed, he was ready to bring both clones, and also take pills to improve, in order to deal with what he said to the business bank.

The Snow Cicada clone is still in the early stage of the fourth order, and it can't reach the fifth order in a short period of time, while the third clone Burning Sky has the early stage of the fifth order, and if you take some pills, you can quickly reach the middle stage.

With the resources he has now, it is not difficult to promote the two clones, and it just so happens that when he goes back, he does not need these two clones to act, which is just equivalent to being in retreat.

After waiting like this for a few days, when a chess piece was about to return, Xiao Mu took the opportunity to shrink the Seven Treasures Exquisite Pagoda for it to swallow, and returned to Earth through the space channel.

At this point, a full year has passed since he arrived in the Wild Land, and the earth has entered the new era for 22 years.

He returned to the Celestial City without a word, ending his retreat.

"Brother, you are so amazing, you have only been in retreat for a year and have broken through a small realm."

Xiao Li'er didn't know that Xiao Mu secretly went to the wilderness, and felt Xiao Mu's cultivation after leaving the customs, and she was quite admired.

"You're not bad, you're about to break through."

Xiao Mu smiled faintly, he relied on all kinds of foreign objects, and Xiao Li'er really relied on talent to cultivate so fast.

"It's a pity that it's not enough, I can't deter those alien races, if I break through to the sixth order, they will dare to destroy one of our cities."

Hearing Xiao Mu's words, Xiao Li'er was not a little happy, but felt that it was far from enough.

"Take your time, the matter of breaking through to the sixth order, where can it be done in a few years."

Xiao Mu touched Xiao Li'er's head, came outside, and had a meal with his parents.

"Oh, brother, let me tell you something, Sister Cao Mei is about to break through to the fifth order, and you will be able to have a child then."

Xiao Li'er thought of something and looked at Xiao Mu with a strange smile.

"So fast?"

It's a little surprising that it's not been a few years since I last said this.

"Sister Cao Mei's talent is very good, isn't it normal to spend so many years breaking through than us?"

Xiao Li'er took it for granted, "Could it be that you're scared, brother?" ”

"What am I afraid of?" Xiao Mu pouted.
