On the Seven Towers

"I knew that the super holy weapon was not that easy to use." Xiao Chen said. "If the situation of the Seven Towers is similar to that of the Spirit Tower, how many crystals will it cost?"

"Although I don't know the current situation of the other six towers, the essence of our seven towers is the same. If you can find them, they should all be in this state. Back then, we calculated the cost of a real battle of the Seven Saint Towers. It takes about one hundred tons of crystal.”

"One hundred tons?" Xiao Chen gasped, "This kind of consumption is equivalent to the annual output of several large crystal mines under the name of China Tower. I don't know how many machines can be operated and how many guns can be equipped."

"After all, you are going to exile a god to a different space. Of course, the cost is huge. You need to accumulate a lot of magic crystals in the past two years." Ta Ling said.

"Now I regret that the territory I won is not big enough." Xiao Chen said, covering his forehead.

Then, they came to the ordinary library higher up. The library has two floors, one for ordinary books and one for professional magic books. Volumes of books were placed in categories in magically protected bookshelves. Xiao Chen and the others took a brief browse and found that many of the magic books here could supplement the magic collection of the Hewan New City Library.

Xiao Chen found a small independent bookshelf with a sign reading Earth Books. There are many books on the bookshelf, more than two hundred.

"This is something I summarized and compiled based on my memories before time travel, and it played a very important role in the development of the Tower of Spirits," Ta Ling said.

"You can actually remember so many books you have read in the past?" Xiao Chen asked.

"You should know that there are a lot of memories stored in the brain, but because of forgetfulness, we have lost the means to obtain them. There is a holy-level spell in the Tower of Spirits called Soul Exploration, which can find out all the memories of your life. , and then fixed them. I only remembered so many books after using this magic on myself. Of course, the price I paid was not small."

"This spell doesn't seem as beautiful as it appears." Xiao Chen said.

"Yes. In fact, this spell is also considered a forbidden spell in the Tower of Spirits. Only those who have been jointly evaluated by two saints are qualified to use this spell on themselves or others. As long as one saint thinks it is inappropriate, This magic cannot be performed, but even so, this spell is still very dangerous, because remembering and remembering the memories of the past life in a short period of time will put a lot of pressure on the soul. There are unbearable memories deep in the soul of the magician, which will cause more serious harm to him. Some people have drastically changed their personalities and even suffered from mental illness because of this magic. I missed the past world and it took me more than a month to calm down.”

Xiao Chen could understand what He Jin said. When time travelers like them arrived in this world, no one would not miss every bit of the past world. It would be very sad if the memories of the voices, smiles, and interactions of relatives and loved ones from the past suddenly emerged. If this person has also suffered major misfortune, it must be very painful to experience it all again.

Soul exploration seems to be a very dangerous magic, but Xiao Chen is very interested in it, "Ta Ling, do you still remember this magic?"

"This holy level magic is recorded in the inheritance room. If you have the right qualifications, you can naturally learn it. However, I still want to remind you how dangerous it is."

Xiao Chen nodded and stretched his hand towards the bookshelf. The magic protective light curtain on the bookshelf naturally receded to both sides. He picked up a book at random and found that it was a compendium of psychology. He glanced at the catalog and it was similar to psychology books seen on Earth. Just added a chapter at the end: the guiding significance of psychology to soul-like magic.

"Lots of psychology books."

Ta Ling said: "Before traveling, I was a teaching assistant majoring in psychology."

"Hua Xia University?" Xiao Chen asked.

"How do you know?"

Xiao Chen said: "I also know a lot of things. According to the time you traveled through, you should be active in the eastern part of the campus, right?"

"Yes. What the hell is going on?"

Xiao Chen said: "Don't worry, I will tell you slowly later."

When Xiao Chen and his party came out of the library, Mao Kai had already put the two books in his hands. "It's interesting. Let's take it back and read it first. It seems to be helpful to a magic model problem I was thinking about before."

After that, they visited several laboratories. The laboratory in the Tower of Spirits had a special feature. There were two common devices in most laboratories. One was a transparent glass room. The tower spirit told them that this was a device specially used to restrain souls, called the Soul Chamber. After any soul is put here, it can show its own form, and various mental fluctuation data will be measured and displayed on the light screen on the side. The wizards of the Tower of Spirits will use this device to test the soul. magic.

Another device is like an upright transparent coffin, with various brackets and shackles to fix the limbs and head. Obviously, this set of things is used to deal with living people. According to Ta Ling, some magic experiments must be performed on living people, and this is their experimental platform.

Seeing these Xiao Chen and others felt a little chilled in their hearts. They wondered whether the Tower of Spirits' current achievements were the result of how many people were shouting and howling here. The mages of the Seven Towers era were definitely not messengers of justice. They often resorted to unscrupulous means when fighting against the God of Nature.

Each laboratory has a special bookshelf with many experimental reports arranged in date order. The experiments conducted by the Spirit Tower to study the soul are very detailed, and many of them are specific to the effect of a certain magic on a specific group of people, or the effect of different auxiliary materials on the same magic.

When Mao Kai came out of the laboratory, he had two more experimental reports in his hand. "It must be said that the Seven Towers era with the participation of time travelers and the current era dominated by empires and kingdoms are completely different things. That was a civilization era that was much more developed than the present. Look at these reports, whether it is logic or format, or even writing standards, they are all the standards of our time. Putting them in the current laboratory in Hewan New City, it is not abrupt at all. In my opinion, the things we found in the library and laboratory are even more valuable than the Spirit Tower itself. They can greatly reduce our development time in many fields. I suggest that all these materials be transported out, and immediately connected to the school through the teleportation array, and all these materials be transported back and put into use immediately. I believe that we will soon be able to achieve breakthrough progress in many aspects."
