Is poseci Tang San's grandmother?

No, poseci is Tang San's great-grandmother.

Because Tang San is Tang Chen's great-grandson and poseci is Tang San's great-grandmother. It is also a kind of fate that great-grandmother and great-grandson met in the way of "Nine Tests of Poseidon".

Poseidon has been waiting for 100 years in the animation, but this person has never appeared. Now, this man has appeared. He is Tang San. Poseci's heart is full of doubts about whether Tang San can really pass the exam and inherit the status of the house of God. After all, Tang San is a mainlander, and Poseidon's exam is much more difficult for mainlanders than Poseidon Island.

The power of poseci.

As Tang San's great-grandmother, poseci's position is naturally not weak. She is a powerful storm, with strength of 99, and Poseidon is the soul of martial arts, and Poseidon is also the title. As Poseidon, her strength is absolutely beyond doubt.

When she reached the ninety-ninth level of soul power, she passed the top eight exams and became the high priest of Poseidon Island. After becoming a high priest, poseci guarded Poseidon Island with the Seven Pillars Guardian. Poseci is invincible in the marine field.
