Mo Fan decided to apply for the Fire School when he was asked to join the exchange team by the Dean which he agreed to after getting the Focus Necklace.
As for Lin Feng he joined the Earth School instead, he decided to have Earth as his primary since he talent empowered that element.
As for the student exchange event he refused, why should he put his life on line in Jinling, he wasn't being paid a Focus Necklace and neither was the rest of the students but they didn't know Mo Fan was 'given' something.
As for the whole experience thing came up for discussion he simply showed the Dean his Hunter file.
In fact was more likely to be safe in Jinling, he was stronger than before. Firstly the exchange competition wasn't until a few weeks later just before their next semester began.
Mo Fan cultivated until then and even used up his opportunity in the three step tower. His Fire and Lightning Nebula hit the third level already while his Shadow and Summoning was at the second tier. He strengthened his basic Fire spell to the fourth tier while his Swift Star Wolf was also bit stronger than what he would be at Jinling.
Mo Fan had been cultivating his wolf properly this time around but he didn't expect it to grow stronger than the canon. But he appreciated it's courage enough during the various missions they did to enlighten it's master.
Since he wasn't going the rest of the team was the same.
....
A week or so later he heard the news from Zhao Manyan but he wasn't sad, he knew his friend was alive but in trouble. He was also pissed at Dean Xiao for not telling him.
While he was preparing to help the guy he decided to use half of his cultivation time in the three step tower, this time he would improve his Earth Element and bring his Light element to the limit of the second tier.
