The task Si Er took on was actually similar to Yu Beixuan's, which was to kill evil cultivators.

Yu Beixuan went to kill those who cultivated demonic arts, and he went to kill those who cultivated spiritual arts.

The only pity is that he can't, like Yu Beixuan, reclaim some of the power from evil cultivators while killing them.

But it doesn't matter, as long as the payment is right, and he can still loot the corpses.

Those evil cultivators are known for killing and robbing, and they possess many valuable items. Once the evil energy on them is purified, even if Si Er doesn't need those items, he can still list them on a trading platform to exchange for what he does need.

Even if you can't get anything good in return, you can still sell it for some spirit stones.

As Si Er posted more items for trading, some people noticed something amiss and started asking him to purify things that were imbued with yin energy, evil energy, or malevolent energy. Si Er followed Feng Yingzhi's example and had them all post tasks at Yun Cang Tower first. This way, he could obtain both spirit stones and materials, as well as corresponding points.

Those points can be used to buy many good things in Yuncang Tower.

After Si Er's reputation grew, he became a walking treasure. Many people wanted to capture him and have him purify things for their forces for free.

However, the Upper Realm does not allow cultivators to seize things by force, so they can only try to lure Si'er into joining their forces.

Si Er always politely declined, but in doing so, he also managed to promote himself, suggesting that anyone with relevant tasks could post them at Yun Cang Lou, and he would accept any task he saw that offered a reward he liked.

Over time, various factions learned that the four of them liked materials that could be used to build ascension passages. When they wanted to ask for their help, they would prepare the necessary materials in advance.

During this time, Si Er and Yu Beixuan also frequently faced assassination attempts by evil cultivators. However, none of the evil cultivators succeeded in their assassinations; they all ultimately became tools for the two to exchange for rewards.

More than a hundred years later, the four finally gathered the materials for the two ascension passages. At this time, their cultivation levels were also close to the critical point of ascending to the Immortal Realm, so they took advantage of their family visit leave to go back home.

That's right, Si Er thinks that the rule in the Upper Realm that allows one to return to the original continent for three days before ascension is similar to a family visit leave.

While others can take their family visit leave regularly, Shang Yu can only take it once in his lifetime.

Moreover, after this family visit, I don't know when I'll see my relatives again.

The four of them were in an even worse situation. They had to work overtime for three days to complete the ascension passage, and they didn't even know if they would have time to say goodbye to their loved ones.

The four returned to their respective continents. Si Er and Yu Beixuan returned to the Myriad Beasts Continent and began searching for the most suitable place to establish an ascension passage.

Qianqiu suggested, "Let's use the original location of Shashen Mountain. It's in the very center of the Beast Continent, and I think it's quite suitable."

"Moreover, that place is equivalent to the original graveyard of the evil god, which is very unlucky for most cultivators."

"If it were changed into an ascension passage..."

Yu Beixuan frowned: "Won't others find it even more unlucky?"

Si Er laughed and said, "I think it's pretty good over there. Although the evil god is already dead, it won't affect anyone's ascension."

"But if anyone fails to ascend in the future, they can say it was caused by bad luck or evil spirits."

"In that case, the people of the Beast Continent should never forget the God of Slaughter, right?"
