"Words? What text? Liu Xuan never thought that there was a great mystery to the things left by Professor Ma, it seems that Professor Ma left something behind Liu Xuan when he died.

"I don't know what the text is, but I've seen it in ancient books, so I can scan it on the computer and let the computer parse it directly." Mu Guang proposed. He was also interested in this matter.

Without further ado, Liu Xuan took off the pendant, walked towards the scanning machine, put it away gently, took a deep look again, and returned to the office, where the computer's scanning had begun.

Mu Guang sat in front of the computer and began to operate, there were too many words before the formation of the Earth Federation, and now he can only wait patiently for the matching and comparison of the computer.

"This cylinder is not simple, you old-timer seems to be able to hide something." Mu Guang stared at the computer screen and said to Liu Xuan with a puzzled face.

"The results are in?" Liu Xuan thought that the analysis results of the text had come out.

"See for yourself." Mu Guang pointed to the computer screen and motioned to Liu Xuan to see it himself.

Liu Xuan leaned over and saw that this scanner not only scanned out the text, but also analyzed the internal structure of this cylinder by the way, which was more complicated, but fortunately, the computer was more intelligent, and marked the names of many parts in it one by one, many of which were real technologies that Liu Xuan had not heard of. It seems that the friend that Professor Ma found in order to make this cylinder is not simple.

One of the most conspicuous devices inside is the electronic signature chip, by approaching the matching lock, you can open the lock, some other parts Liu Xuan can't understand, but according to the introduction of the computer, most of the other hardware is to increase security and exist, and even Liu Xuan found a small detonator inside. It seems that if something goes wrong in one area, this small detonator will explode, causing irreversible damage.

Liu Xuan is now completely puzzled, in his memory, Professor Ma is indeed an extremely rigorous person, but Liu Xuan did not expect to load rigor into a small machine.

"It's an electronic key, to be exact." Mu Guang saw that Liu Xuan was pondering, thinking that he didn't see what this was, so he reminded him beside him.

"I have the key, where is the lock?" This is the problem that bothers Liu Xuan the most at the moment, and at the same time, Liu Xuan suddenly had a flash of inspiration, and his whole body was shocked, and he thought of a place, a place that seemed abnormal at the beginning.

"Drop!"

The computer made a sound, and it seemed that the text had been parsed out, and there were only two sentences on the entire computer screen.

"I'm waiting for you here."

"It's the key to the future."

Mu Guang didn't know the relationship between Professor Ma and Liu Xuan, and at this time, he became even more puzzled when he saw such two sentences. Liu Xuan next to him was very shocked in his heart. He already had a guess in his heart about what these two sentences meant.

Ignoring Mu Guang's gaze, he ran directly out of the office, took out the cylinder, or electronic key, from the scanner, and walked towards the elevator to the underground city.

Get out of the elevator, change the route, and head straight to the cemetery at the edge of the dungeon.

On the way, Liu Xuan was full of emotion.

The meaning of the first sentence is very clear, "I'm waiting for you here" explains the location of the lock, and then thinks of the peculiarity of Professor Ma's tombstone that Liu Xuan saw, and can directly determine that the location of the lock corresponding to this electronic key is in Professor Ma's resting place, that is, in the cemetery of the underground city.

The second sentence reminded Liu Xuan, before he fell into a long sleep, he seemed to have discussed the issue of material fission and fusion with Professor Ma, and Professor Ma at that time also put forward the theory that everything can be fission or fusion, and then because of some things Liu Xuan had forgotten, I didn't expect Professor Ma to remember.

This second sentence let Liu Xuan probably know what Professor Ma left behind, which can indeed be called the key to open the future, and people with this can finally travel in the universe for a long time.

Under Liu Xuan's brisk walk, he finally arrived at the brightly lit underground city cemetery, and arrived at the place where Professor Ma was buried, first respectfully paid tribute to Professor Ma, and then touched the strange place on Professor Ma's tombstone with his hands, the first place is the place where the solar panels are, and the second part is the name on the tombstone, Ma Xuan.

There is no hidden mechanism in the place of the solar panel, it seems that it is the place where the device in the tombstone is usually provided with electricity, which also shows what mechanism is in the tombstone in another aspect, no wonder Professor Ma built his own tombstone before his death, it seems that he wanted to make this tombstone into a tight safe, indeed, who would have thought that there are many secrets hidden in the tombstone.

Looking down is the most conspicuous two big characters on the tombstone, the last time I came, Liu Xuan just felt it, these two words look a little awkward, not that the font is not good, but I feel that these two words and the tombstone are a little flawed, because the inside of the two words looks like there are a lot of potholes, I don't know that this stone is not well selected.

Liu Xuan had already seen that something was wrong last time, so when he came out of the research room this time, he also brought the most ordinary magnifying glass, not that Liu Xuan didn't want to bring other equipment, but because it was very troublesome to borrow the equipment in the research room, and those equipment were very heavy, Liu Xuan had no choice but to choose a magnifying glass.

Liu Xuan also believes that the simplest things are often the most practical things.

Liu Xuan took a magnifying glass and looked for the two big characters little by little, now he is most fortunate that there is no one else in the entire cemetery, otherwise his behavior will be a bit disrespectful, after all, the people who can be buried here are some old professors who are very interested in exploring the universe.

It didn't take long for Liu Xuan to see that there was a different small hole in the point of the Xuanzi, and the other depressions were in = and the tombstone were one, and they were obviously all stony, but this small hole in the depression had very deep hidden traces around it, and the center of the place seemed to be metal products. If Liu Xuan hadn't taken a magnifying glass, Gu estimated that it would be difficult to see the magic of this small hole.

"What is this?" Liu Xuan put down the magnifying glass in his hand, stretched out his right index finger, and gently stroked the place.

"Squeak."

As soon as Liu Xuan's finger was put up, the tombstone made a gentle squeaking sound, and Liu Xuan suddenly realized that this metal product turned out to be a high-sensitivity fingerprint reader! This squeaky sound seems to be Liu Xuan's fingerprints that triggered the mechanism in the tombstone!
