Mu Tao and Mu Niu could very well see the anger in Lin Mu's eyes and knew that it was true. Emotions such as those could not be faked and they would know the best, since they had once felt the same.
"How will you help us, senior? We have nothing to compensate you with." Mu Tao said respectfully.
Now that it was established that Lin Mu was not here to harm them and only wanted to help them, he wondered at what cost help like that came. Even if Lin Mu had said that they had the same enemies, it did not mean help like thee could be free.
"Rather than just helping, I would say this would be an alliance. The person targeting you is far more powerful than you think. In fact, the one that previously attacked you was merely just a subordinate of that man.
Right now, I'll help you stabilize the Mu clan and exterminate the enemies that are close. Once that is done, we will be able to progress further." Lin Mu replied, before explaining the entire situation to them.
