Answer 2

It seems like you are describing someone's experiences in the past. The correct verb forms to complete the sentences would be:

"He looked for traces of ancient civilization and found a lot. Oh, how happy he was, I really envied him. Now, I am thinking about joining their expedition."

These sentences are in the past tense and indicate actions that have already taken place. If you are considering joining their expedition at the current moment, you can say:

"Now, I am thinking about joining their expedition."

Remember to use the appropriate tense to match the context of your sentences.
