The diary from the Ice and Snow Kingdom, this is perhaps Jack's biggest gain in the past three years. All his persistence is to reopen the door of time and space, and vows never to set foot in this fantasy world after returning to Earth. Although the magic teleportation tower has been breached, its energy is too small, and such a huge magic device can only teleport thousands of miles. And this small piece of jade in his hand can open the door of space, comparing the two, it is very scary to think about it!

The treasure that has been handed down in human history and was taken away by the betrayers may be the necklace around the neck of the Ice Queen. Whether it is or not, it is obviously a very important clue, even if it is a 1 in 10 million chance, it must be 100% effort. To return to Earth, to return to family. "Looks like we're going to the Far North!" Jack silently decided.

After reading the thick diary, it was already past 1 o'clock in the morning. Jack, who had been thrown into it, had not even eaten dinner, and the butler wanted to warn him, but Jack had ordered a long time ago that no one should disturb him while he was reading.

Re-tie the journal with rope and place it on the top level of one of the shelves. Looking at the dozen or so bookshelves in the entire room, like a small library, Jack couldn't help but sigh: "If you don't return to Earth, it seems that you can only be a historian in this world!"

After looking at the room full of books for a moment, Jack walked back to the row of bookshelves against the wall. Reach for an ordinary and inconspicuous ancient book on the shelf. When Jack pulled the book to 45 degrees, the bookshelf against the wall suddenly opened like a door. Behind the bookshelves is a dark corner staircase that leads underground, apparently a secret entrance to a basement.

When Jack saw the doorway open, he lifted a wooden lacquerware box from the bookshelf next to it. The moment the box was opened, the room suddenly felt much brighter, and there was actually a bead in the box that radiated a dazzling light.

At this point, Dom would have been amazed if he saw the bead. Because this glowing bead has a price of thousands of gold coins in the market, and there is no market for it. For ordinary people, this is already a priceless treasure. But those who know know that many noble mansions and kings' palaces are lit with this kind of beads on important occasions.

Jack took the beads as a flashlight and walked into the dark staircase.

After going down 4,5 meters, another corner to the right appears. After walking for a few more meters, a wooden door appeared in front of Jack, with a lock on it.

After taking the key and opening the door, a spacious secret room appeared inside.

After closing the door again and entering the chamber, Jack placed the glowing orb in his hand on a tray on a table. With the light ball in place, Jack sat down on the chair next to the table in the back room.

At this time, the secret room was snow-white under the light of the glowing ball, and the gold coins, jewels, and various magic crystals piled up in the secret room all emitted a seductive criminal light.

However, Jack's gaze did not linger on the gold and silver jewels for even a second. Jack opened the drawer on the table in front of him and rummaged through some letters.

Just a few seconds after Jack looked through the letters in the drawer, the depths of the drawer suddenly flashed a few green lights, this light was so small that it could not be seen without paying attention, and even if someone stood next to Jack, they would not be able to detect these green lights. Because only the perspective from which he was sitting could observe the green signal light.

After seeing the green light, Jack ignored the letters in the desk drawer. Instead, on the edge of the drawer, he pressed the thumb of his right hand up. A second later, two flashes of light flashed again in the depths of the drawer, only this time they were red.

After the red flashed, a large hollow aluminum alloy box suddenly rose from the ground in the corner of the chamber.

Pushing the drawer back into place, Jack walked into the box and pressed it inside. The box slowly sank to the ground, and the chamber returned to its original state, and the ground was leveled again, as if nothing had happened.

It turns out that it's all about security by design.

This secret room is only used to hide people's eyes, and the gold and silver are just to tempt ordinary thieves. And his design in the drawer is to protect against the most dangerous group of people in the world - the Shadow Assassins!

Shadow Assassins can hide their bodies in the air, although they may be standing in front of you, and you can even touch them with your hands. But your eyes can't see, they can only see the air.

Just because you can't see them with the naked eye doesn't mean you can't see them any other way. In this secret room, radar scanning and infrared probes are installed.

The Shadow Assassin, after all, is still a real lifeform. Their bodies can reflect radar waves, and infrared probes can sense their heated bodies. As long as there are other moving objects in the room, and another source of heat. A faint light warning will be given in the drawer.

After finally confirming that it was safe, Jack entered the fingerprint of his right thumb and opened the 'door' to the real secret room.

Jack took the elevator and descended dozens of meters to a basement the size of a football field. The basement here took Jack a whole year to build. In order to build this secret room, he even pretended to be a 'national security project' to lure a construction team from a small county town into stationing. After being stunned, the engineering team was brought to this time and space by Jack, and for most of the year, the engineering team did not see what the sun looked like.

With such a large space being excavated, Jack did not alarm anyone. Fortunately, he can connect the two planes, and the earth and rock excavated here can be transferred to the earth and dumped. You don't have to think of another way in this world. After the completion of the project, Jack paid everyone 5 million yuan, and under the threat of 'revealing the national security project is a crime', everyone was once again stunned and sent back to Earth.

A super basement with three floors, filled with supplies that Jack brought from Earth. This is the greed of the human heart, which can do anything for money. Jack looked at these materials and regretted very much, how much money does a person earn in his life is enough?

Stepping out of the elevator, Jack went up the stairs to the last floor of the basement. Here there is a security control center for the entire basement.

Sitting in front of his computer again, looking at this technological product that does not belong to this world. Jack's mind is still very complicated, originally these computers were only used to edit videos. I didn't expect that they would be able to help them crack the magic teleportation tower in the future, but fortunately, they are relatively solid in mathematics and are also programmers themselves. There is a natural advantage for cracking codes!

When Columbus discovered the New World and caused a sensation in the world, Jack certainly had this careful thought. He shot the video to prove that the Earth is not alone in the universe. As long as the time is ripe in the future, he can release the video, and when the time comes, he will also engrave his name in human history. Jack understood that if it weren't for the loss of Zheng He's charts and archives on his voyage to the West, there would still be Columbus there. In the end, Western countries did not recognize Zheng He's feat! Therefore, he shot a large number of videos from the first time he stepped into this world.

In order to ensure the normal operation of the computer, in addition to the generator in the basement, the roof is equipped with solar panels. As long as Jack doesn't turn on all the lights in the basement, the solar panels on the roof are enough to power the computers and a dozen surveillance cameras.

Having decided to venture to the far north, Jack opens his safe and takes out something big enough to make the world stir - the tears of the goddess.

'Tears of the Goddess', these are the tears that humans and orcs received from the statue of the Moon Goddess when they invaded the Elven Sacred Mountain. Despite the fact that it is only the size of a 2-carat diamond, the magical energy contained in it is staggering.

A magician's normal complete cast is divided into three parts. The first extracts the magical energy from the magician's body, the second obtains a portion of the magic crystal from the wand in his hand, and the third obtains a small part from nature during the casting process.

Among these three steps, the acquisition from nature is the smallest, and it can even be ignored for ordinary young magicians, because they are limited by their abilities, they cannot obtain energy from nature in a short period of time. Therefore, in addition to the cultivation of the magician himself, people place the acquisition of energy in the magic crystal.

However, magic crystals are good and bad, and humans naturally rank them. And the 'Tears of the Goddess' is the one with the greatest energy in any civilization known to mankind. The energy it transmits to the mage per second can even directly release a medium-level spell, without the slightest loss of the mage itself.

If providing an instantaneous burst of mid-level magic per second is not enough to convince the world, its greatest power is that it can form arrays. In the list of magic arrays mastered by humans, the 'Tears of the Goddess' is the only perverted being that can form a 'series circuit'.

You know, magic crystals are like human fingerprints. Their magic fluctuations are not the same as each other. Even if the magic crystals obtained from the same species of demonic beasts are not the same. If it's just low-level magic, then the magic fluctuations caused by the crystal are negligible. However, in the case of high-level magic, with the increase of magic energy, two different frequencies of magic fluctuations can cause the spell to fail, and even the caster may be consumed by the magic, causing irreparable damage to the magician's own mental power.

However, the magic technology that humans cannot master, the elves have perfectly solved this unsolvable problem for humans thousands of years ago. The Magic Teleportation Tower is a perfect example of this, as it can connect hundreds of thousands of magic crystals of all kinds to instantly release extraordinary magical energy to open portals!

Even though humans have robbed hundreds of thousands of magic books in the Elven Queen's library, humans still can't do this, and they can't even copy the eighth magic teleportation tower in human history.

The Tears of the Goddess have been a symbol of royal power ever since they were plundered back to the human world. The 'Tears of the Goddess' in Jack's hand originally belonged to a monarch of the Northern Kingdom, but the tyrannical monarch died in a coup d'état decades ago. And many of his treasures were lost to the people in that coup.

It was then that the Tears of the Goddess could be touched by anyone other than the royal power for the first time. At that time, the price of it was even as high as millions of gold coins on the black market!

The outflow of the tears of the goddess has even caused many countries to send their armies. Because it is impossible for humans to attack the Elven Sacred Mountain again, such a scarce resource as the Tears of the Goddess is something that every ambitious person wants. But for decades, all the kings didn't get their hands on it, but Jack took advantage of it decades later. Looking back now, Jack could feel the corners of his mouth rising!
