From A Stronghold NPC To The Final BOSS - Chapter 869 - 868-bewildered

Yo, Hi! I’m Frank, I made a deal with a demon to pay me some money for receiving a guest for a few days every week.
I had no idea about what I have done.
On May 1st, Conan ‘the God of Death’ came to my house. I was forced to let him in and we get involved in a criminal case.
On May 8th, Bruce Wayne ‘Batman’ came to me. I was forced to follow him to fight crime.
On May 16th, Hannibal Lecter, The Silence of the Lambs, came to my home. I can only say that I really can’t stand my guests.

Jiang Chengxuan accidentally traveled to the world of cultivating immortals, and accidentally obtained the inheritance of cultivating immortals.

However, the aptitude is really low, and he has been practicing hard for a hundred years, but he still cannot be promoted to the foundation building state.

Just when he was disheartened and silently came to a mortal city, ready to end his life here, Goldfinger finally arrived belatedly.

It is detected that the host has achieved the achievement of cultivating immortals for a hundred years, and I hereby reward one longevity fruit, which can increase one’s lifespan by serving it.

The next achievement task is now posted.

Ask the host to clear the level a hundred times. After completing it, you can achieve the achievement of breaking through the level one hundred times, and you can get one chance to successfully clear the level.

Ding!

Ask the host to complete a hundred times of spell practice, and if you achieve it, you can get a jade talisman for the inheritance of the perfect spell.

Ask the host to complete a hundred times of exercise achievements, which can improve the root bone.

Ask the host to complete the achievement of making talismans a hundred times…

Ask the host to complete a hundred enlightenment achievements…

Ask the host to complete a hundred alchemy achievements…

Ask the host to complete a hundred poisoning achievements…

Please host…

Unknowingly, when Jiang Chengxuan heard the prompt from the system again, he was told that there is no achievement worthy of you to complete, because your existence itself is already an achievement that can never be surpassed.
