* In the computer system of the international leader, there is a problem that many databases are only lost for a short time by a virus which does not have a clear identity, although many IT professionals also cannot solve the problem. The Ministry of Defense also contacted Dr. Adam because not only international officials, whose data system was destroyed, and even the system of the Ministry of Defense was destroyed. Dr Adam looked at program data which revealed a virus that consumes a lot of memory in computer systems and spreads quickly to destroy all kinds of technological systems. Even though his unit and the twins were good at handling IT, they couldn't stop the virus from making sarcasm. While they had a headache, he noticed that the booklets that appeared after the virus had swallowed the data reminded him of a library of prehistoric books that had been sealed in the mission map.
* He thinks that perhaps a lot of documents still registered in the computer system, causes the documents compiled by the registration kept in the books to be gradually reduced. He told Kai's partner to complete this mission while the other members explain and renegotiate the balance between the tech system and the original folder through books that need to be improved to once again protect the future of such data loss. if they expect only technological system , it will be dragged into the other part, which is not enough. He handed the key to Kai as the holder and to the twins as the creator of the absorbent chip to retrieve the data when they access the Prehistoric Book Library site.
* Kai and Zoey came to stand in front of the prehistoric book library, which was lined with pyramid-shaped stairs, especially the statues of god cats standing guard outside the entrance. They stiffen to reach the entrance to the upper library, the stairs twisting dangerously up and down. Arrived in the library hall, they saw thousands of golden bookcases floating in the air, with many numbers of programmers flying through the books. They also made their way to the center of the library, seeing many statues of gods from Egyptian mythology, with sundials and shadow clocks carved underneath, and a gold watch that the god Re held as his hand minutes almost points to the image of Earth is melted by firing into the interval domain when all data is destroyed.
* Kai asked the twins to send him a rope to hang up, and when they approached the watch, water suddenly seeped into the library, coming out of many walls, and such a fast speed increased near their neck. It's so hard for those who hit by the force of the water, and with one hand grab the rope and the other hand, touch in search of the keyhole key. Zoey remembered sundials and ghost clocks, that more precise gnomon that divided the night into 50 parts, with two additional "twilight hours" in the morning and evening. The shadow clock gnomon consisted of a long rod divided into six parts, as well as a raised crossbar that cast a shadow over the marks. This early clock was positioned east in the morning, while at noon it was turned west to measure the shadows cast by the setting sun. According to the shadow of the sun shining on the shadow clock, it equals 12 p.m., so we take both numbers and add them up to get number 3.
* Then Zoey pushed the bullet to the side of the clock, spun three times, and the keyhole box came loose, while Dr Adam told them to be careful and lock quickly to stop the time because the data in its place was also destroyed. And there was a severe earthquake near their area. They both managed to move the key to the lock out time successfully, and the Keyhole box was destroyed by a sudden down start with a whirlwind, and the cracked box appeared like a blue diamond ratchet. Zoey hurried to take it by her hand slipped off the rope and fell into the whirlpool, kai saw him, he released his hand from the rope and swam to help Zoey, he kissed her as their bodies pulled down into the whirlpool area, suddenly the light brought their soul back into the body. Kai and Zoey were rushed to the emergency treatment room. And the twins installed the program chip, fetched the data on time, then clicked the pop-up, sent the data to the original source, and the other members also successfully negotiated the requested terms.
