But soon after reaching 5th circle mage rank he just blurts it out because he found that he had read all the books that had been made available to him until then. And he was frustrated about it so in a smoothbrain moment he blurted out his main strength.

Later, a friend of his gets sent out on an assassination mission, his friend manages to obtain the device that controls his s*ave mark (The device, called a s*ave rod can be used to explode the s*ave mark embedded in a s*ave's head by breaking the rod). The assasination mission is one in which there is no chance of returning from. But after his friend retrieves his own s*ave rod, MC still tells him to carry out the assasination mission on the f*cking Chancellor of the kingdom they are in because otherwise the committe will chase his friend. Seriously? You are worried about the committee chasing your friend and not the f*cking kingdom for mu*dering the Chancellor? A Marquis level noble?

Plainly ridiculous.

It's like agreeing to mu*der the president of a country to avoid being chased by a gang that raised you. Bro, why the hell do you think the country's forces wouldn't chase you for killing the president? Why the hell would you think the country's forces would be less scary or capable than some gang's. A country has FAR more capability to chase you to the ends of the earth. And the crime is far more serious. For the gang, the crime they might chase you for would be desertion. The country meanwhile would be chasing you for mu*dering it's most significant figure. The severity is on a completely different level.
