Ajax didn't think that his father was lying about bringing only one person with him into the Secret World.
Instead, Ajax believed that he had already become much more powerful than his father at his peak and the more powerful he became, the more powerful and useful the system would become.
Therefore, Ajax could tell that he could bring more people with him compared to his father back then.
"Yes, Father."
Even though he learned that he could bring 100 cultivators with him, Ajax didn't explain it to his father and nodded his head at Aron's words.
"Let's go then."
Soon, Ajax flew towards the cave Ren had settled in and after explaining something, Ajax was all set to enter the Secret World.
As for Ren, he learned from Aron that Ajax had a way to enter the secret world already. So, he was not surprised much; however, he was excited about returning to the Secret World and meeting his old acquaintance.
