The golden leopard's eyes lit up and said, "Yes, this is a good thing, so let's do it, a high-level creature corpse, I'll give you a thousand energy coins, a top-level creature corpse, I'll give you ten thousand energy coins!" ”

Yang Xiaole compared the market price he knew, and finally nodded and said, "Deal!" ”

As a result, Yang Xiaole obtained more than 20,000 energy coins from the money leopard.

Coupled with the energy coins he had harvested from killing the Werewolf King and many werewolves, his energy coin reserves had reached more than 50,000 points.

It's a pity that his attributes have reached the limit of mortal-level creatures, and even if he strengthens more bloodlines, he can't improve his attributes for the time being, and at most he can get the ability of that creature.

Yang Xiaole didn't know if he could compensate for improving his attributes after he advanced, so he decided to save the 50,000 energy coins for the time being to see if there were any necessary exercises or skills to buy, if not, he would wait until he broke through the realm in the future and then use it to strengthen his bloodline.

After completing this mission, Yang Xiaole was given another seven days of vacation.

After some thought, he spent Energy Coins to teleport back to Mother Earth.

Then, Yang Xiaole continued to lead the corpse demon king and the zombie army and embarked on the journey.

This time, Yang Xiaole let the zombie army kill those junior zombies, and at the same time let the World Tree Seed absorb soul energy.

After the World Tree Seed absorbed enough soul energy, Yang Xiaole used the World Stone to open the space channel, allowing the World Tree Seed to absorb the space energy to neutralize the soul energy.

While feeding the seeds of the World Tree, Yang Xiaole was not idle, and began to crack the spells on equipment such as the Hideous Mask, Golden Light Treasure Armor, Acceleration Shoes, Immortal Jade Pendant, Ninja Suit, Dark Robe, and Dark Staff.

With the help of the experience accumulated in cracking the Blood Shadow Escape, Yang Xiaole quickly made some progress.

On the first day, he successfully cracked the acceleration technique on the acceleration shoe, and he was able to perform the acceleration technique on his own.

Moreover, the acceleration technique he performed by himself can be superimposed with the acceleration technique on the acceleration shoes, which doubles the speed of thinking.

Using this acceleration technique, Yang Xiaole can use it for two days a day, and he can crack the spell even faster.

The next day, he cracked the three shield spells on the Golden Light Treasure Armor, the Immortal Jade Pendant, and the Dark Robe, and integrated their principles to form his own original full range of energy shields.

On the third day, he cracked the dark lightning of the Dark Staff, the fear spell of the Hideous Mask.

On the fourth day, he cracked the ninja suit's shadow escape technique and doppelganger technique.

At this point, he didn't have any spells to crack, so he began to practice them repeatedly.

Seven days later, Yang Xiaole finally mastered these spells, and at the same time, he also used the Corpse Demon King to bring most of the high-level and middle-level zombies in this world under his command, and the strength of the zombie army reached 10 million.

With the help of this huge army, Yang Xiaole exterminated tens of millions of primary zombies, and let the World Tree Seed absorb enough soul energy and space energy.

Finally, the World Tree Seed suddenly transformed, bursting the black box and turning into a small world.

This small world is spherical in shape, one meter in diameter, and appears to be translucent, and there is nothing inside.

Because there is Yang Xiaole's soul distraction in the Xiaoqian world, Yang Xiaole feels that he seems to be able to control this Xiaoqian world.

Seeing Yang Xiaole's heart move, this small world suddenly turned into a white light, burrowed into Yang Xiaole's eyebrows, and integrated into his body.

After the small world was integrated into his body, Yang Xiaole felt the situation of this small world more clearly.

It turns out that this small world really only has one cubic meter of space, but it seems that it can devour treasures and continue to evolve, especially space treasures, which will have the strongest effect on its evolution.

Yang Xiaole tried to take out a ten-cubic-meter space bracelet and let this small world devour it.

As a result, Xiao Qianjie swallowed the space bracelet in one fell swoop.

Soon, the space of Xiao Qian World was raised to ten cubic meters, and several mysterious substances appeared in it, which seemed to be the residue of Xiao Qian World after devouring the space bracelet.

Yang Xiaole's eyes lit up, and he muttered to himself: "It turns out that this small world can not only devour the storage space of the fused space treasures, but also decompose and extract its manufacturing raw materials, in this way, it is not a loss, and the decomposed materials can also be used to make equipment in the future!" ”

So, Yang Xiaole took out most of the space treasures he had on hand and threw them to Xiaoqian World to devour and fuse, leaving only the space bracelet containing the miniature nuclear bomb untouched.

Soon, Yang Xiaole's small world evolved to one hundred and fifty cubic meters, and the various materials decomposed in it were also the size of a fist.

Yang Xiaole was still not satisfied, so he tried to let Xiaoqian World devour various materials of the Earth Mother Star, including air, water, and soil to evolve.

As a result, that little world really came and devoured the material of the mother planet.

In this way, the space of that small world began to slowly increase again, but the speed of devouring ordinary matter was a little slow.

In the end, when Yang Xiaole was about to teleport away, there was already two hundred cubic meters of space in the small world, as well as a ground area of one hundred square meters, and a sky about two meters high, which could barely accommodate more than a hundred people.

Moreover, this small world can also absorb the light from the outside world through Yang Xiaole, so there are virtual suns and moons in the small world, which can be used for lighting and plant growth.

Yang Xiaole looked at this small world that had been slightly formed, and his heart moved, and he summoned ten high-level zombies and one hundred middle-level zombies to collect them inside.

If you encounter some situations that require cannon fodder, it would be a good choice to send these high-level and mid-level zombies.

Moreover, those high-level zombies each have abilities, and the middle-level zombies are proficient in the use of weapons such as bows, arrows, swords, etc., which together are also a strong tactical force.

At this time, it was almost time to carry out the next mission, and Yang Xiaole had no choice but to teleport back to Earth.

As soon as he teleported back to the public space, Yang Xiaole saw Liu Xuemei, Su Ying, and Li Jinyan standing there very seriously, as if they were waiting for his arrival.

"What's going on?" Yang Xiaole asked in amazement.

Liu Xuemei said solemnly: "We received the news that Chu Ao was unwilling to fail, and sent the Assassin Hall under the command of the World Tyrant Alliance to hunt us down, the people in this Assassin Hall are all masters, and they are good at assassination, and many powerful teams have been wiped out in the hands of the assassin team they sent!" ”

Yang Xiaole raised his eyebrows when he heard this, and said confidently: "Yes, then let them come, I will let them have no return!" ”
