"Professor Ge Lin also had several students before, but they all died in the practice of the 100,000 mountains, and the professor thought that he did not take the students well, and he blamed himself very much, and then he no longer accepted students and did not live with students." Pope said.

"Pop and I are the last two students accepted by the professor, and it was Dean Augustine who forcibly stuffed the professor back then, and the dean was worried that the professor would be lonely, the professor has always lived in a very remote place, and he didn't interact with other professors, only Teacher Mary occasionally came to deliver some food and clean up." Helsinki went on to say:

"In fact, more than ten years ago, the inner courtyard just moved into the 100,000 mountains, and many of the facilities and rules are not perfect, and the mortality rate of the college in the 100,000 mountains is already very high."

"Ah, it's really Miss Mary." Suddenly, the division excitedly walked towards a woman who was using magic to carry food, and the two of them, who hadn't seen each other for a long time, quickly chatted.

"Teacher Mary is the teacher who recruited Si Si into the outer courtyard of the Holy Academy, speaking of which, she introduced me to Si Si and I met, I haven't seen her for a long time, but I didn't expect her to be in the inner courtyard." Arlo explained to the two Helsinki for the priest.

"Well, Teacher Mary is in charge of the internal staff of the inner courtyard, and she will also help when the enrollment of the outer courtyard is crowded."

As they spoke, they had already arrived outside Professor Green's residence.

Professor Green's residence is very special, it is actually a treehouse built on two huge trees.

It should have been built for a long time, and the house was already tightly intertwined with the trees.

"What a cute treehouse, Arlo will build one when he goes back." Siji has broken up with Mary and is surprised to go under the treehouse.

"That's not easy, these two Gegegidi trees were found and planted by the professor with great difficulty." Helsinki Road.

"What is a Gegejidi tree, can't you use other big trees to make a treehouse?" It's rare to have a plant that you don't know and don't understand.

"It is best to use Gege Gidi trees for tree houses, it is warm in winter and cool in summer, and it will not grow insects. If it is more than 1,000 years old, the Gegejidi tree can also nourish the muscles and veins and prolong life. ”

It was a silver-haired old man who had come down from the treehouse, his wind magic that could fly into the air, much more powerful than Grigory and Arlo's.

By this time, Helsinki and Pope had already saluted and shouted, "Professor." ”

Alos naturally understood the identity of the comer, and hurriedly saluted: "Hello Professor Green. ”

Greene was a kind old man, smiling and using wind magic to send them to the treehouse to sit down.

Si Si's attention has been on the Gegejidi tree, here and there: "Nourish the muscles and veins and prolong life, is the Gegejidi tree so magical?" ”

"Of course, but this is at least a thousand years old Gegejidi trees, these two trees are only more than ten years old, alas, alas, it's a pity, I'm afraid that the thousand-year catastrophe is coming, and they won't live until then." Greene sighed.

"Why can't you live, will the thousand-year catastrophe still affect the growth of the tree?" Si Si asked.

"I've heard Hull relay your understanding of the Millennium Catastrophe, and think that the Millennium Catastrophe should not only refer to the battles between various races, but also include a series of natural disasters.

"However, since Professor Greene knows that a Gegegidi tree that is more than a thousand years old can prolong life, it means that there are Gegegidi trees that live for a thousand years." Arlo immediately thought.
