Liu Shiming suddenly received a call from a female colleague of the archaeological team in the morning, saying that the coffin seemed to have undergone new changes. As for what the changes were, the colleague did not know, only that many experts had already hurried to Tianhai University.

Out of curiosity, Liu Shiming decided to go to Tianhai University to have a look, and Liu Xing and Wang Lanlan naturally didn't want to miss such a good thing.

The three of them rode a motorcycle, and after more than ten minutes, they successfully arrived at Tianhai University and went straight to the Institute of Archaeology together.

Although the coffin of Yufeng Mountain has been unearthed for more than half a year, there has been no breakthrough in related research work so far.

Every once in a while, there are media reports that the expert group has devised a new research protocol, but the final study always ends in failure.

At present, the archaeological institute is no longer guarded by the police, and only a few security guards are responsible for checking and registering the entry and exit of personnel.

After registration, Liu Xing, Wang Lanlan, and Liu Shiming walked into the Institute of Archaeology and came to the No. 1 Archaeological Research Room on the third floor.

When the three of them walked to the door, they saw more than a dozen experts gathered in the research room, including Professor Juan, Dr. Zhao Cong, Professor Sun Yi and others.

At this time, all the experts were standing around the coffin, their eyes focused on the light screen on the surface of the coffin, and they saw a new prompt message displayed on the screen:

"Password hint: Excuse me, who is the protagonist of "Heaven and Dragon Slayer"?"

Looking at the new password prompt on the coffin, all the experts frowned and secretly thought.

"Why does this password prompt appear in the coffin?" Professor Juan was full of doubts, "Wasn't the previous password hint all "The Legend of the Condor Heroes", why did it suddenly become "Heaven and Dragon Slayer" today?"

Dr. Zhao Cong recalled: "Yesterday I started to use the intelligent robotic arm to crack the code on the coffin, and it took a whole day and a night to crack it. When I came in the morning, I noticed that the password prompt for the coffin had changed. ”

Professor Sun Yi wondered: "The coffin has been unearthed for more than half a year, and the password has not changed, why did it suddenly change today?"

"It should have triggered the anti-theft mechanism of the coffin. Dr. Zhao Cong speculated, "I used my intelligent robotic arm to crack the code 24 hours a day yesterday, and the coffin may have activated the anti-theft mechanism to generate a new password protection." By the way, what kind of book is this "Heaven and Dragon Slayer"?"

Professor Juan sighed: "Just halfway through, I have already checked on the Internet, and there is no information about "Heaven and Dragon Slayer" in our country, this book should be the same as "The Legend of the Condor Heroes", it does not belong to our era. ”

Professor Sun Yi pondered for a moment and said, "I think the two books are inextricably linked, and "Heaven and Dragon Slayer" is likely to be an upgraded version of "The Legend of the Condor Heroes". ”

"I think the same thing as you. Professor Juan agreed, "According to my previous theory of prehistoric civilization, The Legend of the Condor Heroes was a war between ancient humans and eagle beasts, and humans at that time were supposed to bombard eagle beasts with cannons and other weapons on the ground. By the time of "Heaven and Dragon Slayer", the war may have escalated and turned into a high-altitude war. 'Yitian', as the name suggests, means to fly in the sky, which indicates that humans are fighting dragons and beasts in the air. ”

Dr. Zhao Cong wondered, "How did ancient humans fight in the air? Could it be that they invented a fighter plane-like flying machine? By the way, what are dragon beasts?"

"It's hard to say. The giant paleontological fossils discovered by the Huaxia Institute of Biology before were not carved beasts, but dragon beasts?"

……

Experts involuntarily started some discussions around "Heaven and Dragon Slayer", the active Professor Juan put forward many conjectures about prehistoric civilization, and history professor Sun Yi continued to adhere to his theory of future civilization.

As for the other more than a dozen experts, they all have their own opinions on the new "Heaven and Dragon Slayer" that appeared today.

Due to the sudden change of passwords, all the experts came temporarily, and the relevant materials and information were not fully prepared, and it was difficult to discuss some issues in depth.

After some discussion, the expert group decided to go back and sort out their thoughts first, and then hold a seminar in the evening.

Half an hour later, all the experts walked out of the research room, and only Dr. Zhao Cong stayed alone, and he continued to use his intelligent robotic arm to crack the code of the coffin.

As soon as the expert group left, Liu Xing and Wang Lanlan slipped into the research room together and gathered next to Dr. Zhao Cong to watch.

Soon, Liu Xing's attention was attracted by an intelligent robotic arm next to the coffin.

This intelligent robotic arm was developed by Dr. Zhao Cong and several computer experts and mechanics, and is mainly used to crack the code of the coffin. Not only is there an intelligent program embedded in the arm, but it also has an integrated text library, which is able to automatically enter text by clicking touch buttons on a book coffin like a human arm.

The advantage of the intelligent robotic arm is that it can crack the code 24 hours a day.

At this time, the robotic arm is running, and its mechanical fingers are tapping the screen of the coffin at a rapid speed, and it is constantly typing words.

"One soil. ”

"Wrong password, please re-enter it. Password hint: Excuse me, who is the protagonist of "Heaven and Dragon Slayer"?

"Ichikawa. ”

"Wrong password, please re-enter it. ”

"One bite"

"Wrong password, please re-enter. ”

……

The intelligent robotic arm entered one answer after another, although all the answers were wrong, but Liu Xing still felt that it was amazing, and the intelligence of this arm was still quite high.

"Dr. Zhao, can this arm crack the code of the coffin?" asked Wang Lanlan curiously.

"It depends on luck. Dr. Zhao Cong explained, "There are hundreds of thousands of characters in Chinese characters, and there are more than 1 billion ways to combine and arrange them. Even the commonly used text has more than 5,000 words, and there are more than 25 million ways to combine them in pairs. ”

Liu Xing basically understood, although this mechanical arm is quite intelligent, it is almost impossible to crack the code of the coffin, unless there is luck against the sky.

The intelligent robotic arm looks novel at first glance, but after a long time, it feels boring, just mechanically and constantly entering words.

Two hours later, Wang Lanlan got bored and left the research room alone to continue looking for her black shadow book thief.

As for Liu Xing, he stayed. Today, almost all the experts in the research room are gone, and there are not many such good opportunities.

Throughout the afternoon, Dr. Zhao Cong was working on cracking the code, and he worked extremely attentively, always staying by the coffin.

At about 3 o'clock in the afternoon, Dr. Zhao Cong made a bag of instant noodles and ate it as a snack. During the meal, he sweated a lot on his shiny head, so he took off his shirt and cooled down first.

"Dr. Zhao, are you so shirtless, aren't you afraid of being photographed by the surveillance camera in the research room?" Liu Xing asked casually.

"The monitoring system of the scientific research room suddenly collapsed a few days ago, and it has not been repaired yet. ”

Liu Xing felt strange: how could the monitoring system of the scientific research room suddenly be paralyzed?

After eating instant noodles, Dr. Zhao Cong stood up and said, "Little ghost, I'll go to the bathroom, don't move the things in the research room." ”

Hearing this, Liu Xing's heart moved, and he turned around and asked, "Dr. Zhao, what are you doing in the bathroom?"

"Nonsense, of course, convenience. ”

"Big or small?"

"Big. ”

After speaking, Dr. Zhao Cong hurried out of the research room alone and went to the bathroom on the floor.

"Dr. Zhao is a big solution this time, and he should have spent more than 3 minutes in the toilet, right?"

Liu Xing pondered alone in his heart, after the coffin was opened, it would take 3 minutes to close, and if Dr. Zhao Cong took more than 3 minutes to go to the toilet, Liu Xing could take advantage of this time to open the coffin once.

Ordinary people generally go to the toilet for more than 3 minutes, and Liu Xing decided to fight it.

As soon as Dr. Zhao Cong went out, Liu Xing immediately came to the coffin, moved the intelligent robotic arm to the side, and his eyes fell on the screen of the coffin, which still showed a line of words:

"Password Hint: Who is the protagonist of "Heaven and Dragon Slayer"?"

Without thinking too much, Liu Xing quickly clicked the buttons on the screen with both hands and typed in three words - Zhang Wuji!

"Congratulations, the password is correct! The system is open, please ...... later"

Airplanes!

Suddenly, the coffin trembled slightly, and a crack appeared on the surface of the coffin, like a door, slowly opening......
