After checking that no one was disturbing around, Li Feng took out the light gate terminal. The terminal of the pen ~ fun ~ pavilion www.biquge.info is actually the terminal that records the plane coordinates of the world of the light of hope, and for a period of time, the coordinates of the world have been changing, but the box can keep in touch with the academy for a period of time.

After the predetermined time, the crate runs out of energy and becomes scrap metal. As for charging? The energy used in the box is not electricity, but a higher level of energy than electricity. Only the academy can be charged.

In a sense, this is also to prevent the chest from being obtained by enemies in other worlds, and use the coordinates recorded by the box to launch an attack on the academy.

With Li Feng's operation, it was confirmed that he had the permission to open, and the light door was finally opened.

It's not that this box opens the light door, but the real light door system in classroom 404 in the college, from standby to opening the light door.

In the very short time it takes to open the light gate, the energy consumed is almost as much as the annual power generation of the Three Gorges Hydropower Plant on the Yangtze River.

From the perspective of energy consumption, opening the light door is indeed a very money-burning business.

One after another, the crowd carried the box containing the gold and passed through the light gate. With the light door closed, everyone had returned to the classroom of Class 404.

For the 140 kilograms of gold brought back by Li Feng and others, 25 students held a class meeting to discuss that the gold would belong to the collective property of the class, rather than taking the private division of the wealth.

After all, if it is divided, each person may be able to share a windfall, but this wealth is more than enough to be more than the upper and lower than the lower, and it will not really improve the strength of the entire class and the survival rate in the more dangerous world in the future.

"The funds are pooled first, and then, in the name of the collective funds of the class, a folding dimensional backpack is purchased." Long Xiaoguang said.

Folding dimension backpack for $1 million. However, a backpack is equivalent to carrying a huge warehouse of 1,500 square meters. If it is used to hold gold in other worlds, it is not more than 100 kilograms of gold, even if the 10,000 tons of gold stored by the Federal Reserve are emptied, there is no problem.

As a group of people traveling and adventuring across planes, it is very necessary to buy such an item. Individuals can't afford this kind of props for the time being, but they can still buy them with collective funds if they save up.

With,Li Feng and Long Xiaoguang compared the time recorded by the electronic watch-this time everyone stayed in the world of "School Apocalypse" for about 2 days. On the side of the Ray of Hope Academy, just over an hour had passed.

"Basically, an hour has passed on our side, and about a day has passed over there, I don't know if it's the same pattern every time." Long Xiaoguang recorded the results on the computer and said to Li Feng, "As for literary and artistic works, they can be sold to the academy." If it's content that isn't in the Ray of Hope's Literary Server for the preservation of the pluralistic world, it can be sold, and different prices are given depending on the quality of the work. The minimum is only $1,000, but if the value of the work is so high, even a single work can sell for hundreds of millions of dollars! ”

"So tall?" Li Feng was surprised.

"Of course, the Light of Hope is a cross-dimensional consortium, and I don't know how many different worlds literary and artistic works are sold." Shen Xuefei stuck out her tongue and said, "Even if you pay a sky-high price to buy the content of the work, you can easily earn it back." ”

Li Feng thought about it, literary and artistic works are small in size and high in value, and with a large number of literary and artistic works in parallel worlds, they sweep the market in other worlds, and the profits earned will not be inferior to any products. After all, no matter how strong the production ability of literary and artistic people in any world is, they can't compare to countless high-quality works from countless parallel worlds.

……

After returning to the Ray of Hope Academy, everyone was the same as ever, except for a very small number of classes per week, and they were idle every day.

However, in order to increase the probability that everyone will survive graduation, Ms. Mary recommends that you take some necessary courses.

"Superpower development, $8 million a semester, if you have the potential for superpower development, it is possible to obtain superpowers ranging from lv1~lv5." "In terms of practicality, I personally think this elective is the most cost-effective. If there are several LV3~LV5 superpowers in a class, and everyone can unite and cooperate to support them until graduation, it is not very difficult. ”

"It's too expensive!" As soon as Zhao Kun heard the price of the course, he felt pitted.

Of course, more students are very interested in superpowers.

"Do you really have superpowers?" Li Feng asked, "This seems a bit out of the ordinary!" ”

"Existence is reasonable." Teacher Mary smiled, "What's more, superpowers have also been developed through scientific means, but this technology is only a few decades more advanced than the technology of the origin world. ”

"By the way, why is our world called the Origin World, and the level of science and technology doesn't seem to be too against the sky!" Li Feng asked.

"Because...... The special **** of this world! Mary said, "Every universe is made up of energy and mass. Energy and mass determine the stability of a universe. When the energy and mass exceed a certain critical point, it may split, and the mass, energy and information of the universe below a certain critical point may all evaporate in an instant, which is also the end of the world. A large number of parallel universes have been discovered, and the total mass is relatively low. In some universes, the total amount of mass and energy is less than one millionth of our origin world. Generally, the smaller the mass of the world, the slower the passage of time, however, we do not have to worry about being surpassed by them, because their entire universe may die out at any time, and the origin world has a longer lifespan due to the total amount of mass and energy that is extremely large, even if it is continuously consumed, it is equivalent to most universes. The universe we live in is the best and most promising universe known, so it is developed by the Hope Light Group as the origin world. As for the so-called level of science and technology is not advanced...... Hehe, that's because you only see the surface! Ray of Hope cooperates with governments around the world, a bunch of black technology projects, but it's not transparent to the public. ”

Long Xiaoguang nodded and said, "Indeed, the water in the Origin World is very deep, for example, our academy, we have never known about it before. ”

Next, Ms. Mary recommended practical courses to everyone, of course, most of them are very expensive to use.

In the end, under the recommendation of Teacher Mary, everyone decided to take a course that would probably be used next-mecha class.

This course focuses on driving, maintenance, and combat of general-purpose mechas, as well as the principles and genres of mecha in different worlds.

"The reason why this class is useful is because ......," Teacher Mary said quietly, "do you remember not long after entering the school, attacking the otherworldly alien species beta in the academy?" ”
