Su Buqing, the leader of the Divine Dragon Sect, was very busy, and after inviting all the teachers to a banquet and expressing encouragement, he handed over the matter of the Asking Heart Academy to the Foreign Affairs Hall.

The Foreign Affairs Hall allocated an old mansion to Wenxinyuan in the north of the city as a school site, but the mansion was too small, with less than 100 acres. Meng Fei was a little dissatisfied, so Chen Hao proposed that the academy be located next to the Nine Abyss Avenue, that is, the spiral avenue in the Nine Abyss Crypt.

This is not just to hold the thigh that is not enough, but the Nine Abyss City is surrounded by high mountains, and most of the middle area is occupied by the Nine Abysses. As a result, the actual area of Jiuyuan City is limited, and the population is large, except for the deserted Jiuyuan below the second layer, it is really difficult to find a large enough territory.

After the inspection, Meng Fei felt that he was barely satisfied. The caves used for living on the Nine Abyss Avenue are also ready-made, and as long as they are slightly repaired, they are not impossible to serve as academies.

Although the terrain is a bit narrow, it is better because there is almost no area limit. Therefore, after negotiation with the Foreign Affairs Hall, Wenxin Academy obtained a ten-mile site at the junction of the second and third floors of Jiuyuan Avenue.

The only drawback is that this long college has very little lighting. Only in the afternoon can you get two hours of light every day.

"Brother Meng...... No, I should call you Meng Sacrificial Wine now, I have a way to solve the lighting problem. However, this requires the permission of the Dragon Cult. Chen Hao had already made up his mind when he proposed the location.

Meng Fei was a little worried, and said: "Lighting can be solved no matter what." I just need to cast a few hundred lighting techniques a day, but it's still not as good as natural sunlight. ”

"You don't have to worry, my solution is to use natural sunlight. Chen Hao said confidently.

Meng Fei was a little unconvinced, he thought that Chen Hao was nothing more than a formation for building lighting, or casting a huge lantern. He could also think of these methods, and all kinds of talents with formations and refining weapons could also be realized. It's just that firstly, these things are not as good as natural sunlight, and secondly, the consumption of long-term operation is also a problem.

But after Chen Hao revealed his plan to him, he felt that this plan was really feasible!

"But how can these large mirrors accurately refract sunlight in?" he still had some doubts.

Chen Hao said: "You don't have to worry about this, I will calculate its position and angle to ensure that it can cast the sunshine all day long." ”

After obtaining Meng Fei's approval, Chen Hao let the Great Yan Array work nervously for an hour before obtaining a detailed drawing.

This drawing, is a set of huge mirrors, combined in a specific way, to form a set of prisms. The prism hangs in the center of the Nine Abyss Crypt and is specifically designed to refract sunlight and illuminate the Nine Abyss Inquiry Branch.

Because this set of prisms actually only needs a floating formation, at most with some reinforcement measures, so that birds and other creatures will not be knocked into it all at once. Therefore, its cost is only 20,000 spirit stones, and the maintenance cost is also very low, which is still within the affordability of the Conscience Branch.

After obtaining the consent of the Foreign Affairs Center, the temple was officially opened.

When it opened, the powerful and celebrities of Jiuyuan City, under the leadership of Su Buqing, the leader of the Divine Dragon Sect, all came to celebrate. But after seeing the humble campus illuminated by lighting, many powerful celebrities were filled with disdain.

In addition, the strength of the teachers of the Question Heart Academy is not very strong, so after the opening of the college, it fell into the embarrassing situation of no students.

However, the matter of enrollment is a headache for Meng Fei and other teachers. Chen Hao took five or six teachers who were good at formation and refining, and began to build the lighting project of Wenxin Courtyard nervously and busily.

Just seven days later, a set of crystal clear, glittering gorgeous prisms hung in the sky above the Nine Abysses!

This set of prisms, after the discussion of Chen Hao and the teachers, was named "the light of the college".

With a radius of 500 zhang, the Academy Light looks spectacular and beautiful, but in reality, it doesn't cost much.

The mirror was originally a luxury, but it was only for ordinary people. For cultivators, long before Chen Hao arrived, they knew how to make mirrors with mercury plating on crystals.

Chen Hao did not use a crystal mirror, although a small piece of crystal mirror was very cheap for a cultivator, but the demand for the light of the academy was too large, and the strength of the cheap crystal was also a big problem, so he still used the bronze mirror.

However, these bronze mirrors, which are added with light-colored alloys, are polished to the extreme, and their brightness is not much better than that of crystal mirrors.

Then Chen Hao added three formations to the inside of the prism, which were floating, stable, and able to protect the prism and the mirror, which was enough to make this cheap and beautiful academy light play a huge role.

The angle of the prism refracting sunlight, after Chen Hao's careful calculation, just meets the normal light of every day.

After the light of the academy rose into the sky, it unexpectedly became a new scenery in Nine Abyss City. At the same time, there is an endless stream of people who come to watch it every day.

There was also an unexpected gain, that is, it brought the first prestige to the Jiuyuan Wenxin Branch, and students began to sign up for the academy.

Although these students are all children of ordinary people, they still make Meng Fei smile from ear to ear. You know, he's almost going to go to the slums to recruit free students!

For so many years, the Asksin Institute has never been free. This is because Xu Ruyan has always adhered to the concept that learning without paying a price will never be cherished.

Moreover, the afterglow of those prisms also benefited the Jiuyuan Avenue near the Wenxin Academy. The caves, which had long been uninhabited, began to become sought-after again.

At the same time, according to rumors, the Divine Dragon Sect has planned to invite the Academy of Inquiry to help them build more Courtyard Lights so that they can make use of these abandoned lots.

"Chen Hao, you are such a genius!" Meng Fei couldn't help but praise Chen Hao, and the teachers also looked at him with admiration.

The idea of this prism is not so bizarre, but it is rare that Chen Hao can perfectly combine spells and exquisite design, which most qi practitioners can't do.

And the combination and angle of the prism, the relationship between the relative sunlight, such a huge and complicated calculation, also makes many qi practitioners not choose this way. Comparatively, they prefer to throw a few illuminations a day.

Yin Xu also exclaimed: "Teacher Chen, with this kind of talent of yours, it is entirely possible to become a top refining master!"

Chen Hao was humble for a while, and then put forward a second suggestion: "Meng Saijiu, I think we should continue the plan to recruit free students, after all, there are still too few students now." ”

"But it was just a last resort. Now that there are nearly 100 students, we can develop slowly, and I think it's better not to change the tradition casually. Meng Fei was a little embarrassed.

Chen Hao shook his head and said, "We won't change the tradition, and we won't really be free." I call this a work-study program. ”
