After waiting for a while, the phone was no longer stuck, Li Hao opened WeChat, and saw Li Cheng send dozens of WeChat messages, he flipped to the top and looked down one by one.

Li Cheng said in the message that he found a manuscript of inferences about traveling through time and space in the relics of that expert friend, and made some bold assumptions and inferences about Li Hao's crossing events in the manuscript, and there are many inferences, but summarized in one sentence, that is, there is a node between the Datang world where Li Hao is located and the modern world are connected, and the bridge connecting these two nodes can be called a space-time tunnel, space-time tunnel is not a novel term, it often appears in movies and China, and there are various versions. However, no one has ever seen it, and the deceased scientist speculates that the space-time tunnel is likely to appear in the form of a magnetic field, invisible to the naked eye.

His inference is theoretically based, because Li Hao can actually communicate with Li Cheng on WeChat in the other world, so it shows that there can be radio waves between the two worlds, but Li Hao and Li Cheng can't talk on the phone, and Li Hao can't send text messages, only the simplest numbers, which also shows that the magnetic field of this space-time tunnel has a fixed direction, and it is one-way.

The expert also made a deference that if the entrance of the space-time tunnel was fixed, then it was very likely to be at the place where Li Hao fell off the cliff, and the exit was naturally at the place where Li Hao fell.

After Li Cheng read the inference information, he was very excited, borrowed a helicopter from a friend, went to the location of Li Hao's accident, and used special instruments to survey the surrounding magnetic field, and finally found that under the cliff where Li Hao had an accident, there was a strong and chaotic magnetic field, so he guessed that the entrance to the space-time tunnel was very likely to be there.

"Even helicopters were used." After Li Hao flipped through this information, he couldn't help but be speechless, secretly glad that he had met such a good brother, although he and Li Cheng were brothers, but their personalities were completely different, Li Hao was too casual and playful, and Li Cheng was a full five good boy since he was a child, he was exceptionally good at everything, he was a soldier for five years and sat in the position of deputy regiment commander, and was also awarded the rank of major, and later because of the injury in military exercises, retired from the army and business, opened a battery factory, first did OEM, and later developed his own brand of battery, just five years, The scale of the factory has expanded dozens of times, the assets are nearly 100 million, and Li Cheng has a wide range of contacts, either rich or expensive, or he is a cadre in the army, so it is really not difficult for him to borrow a helicopter.

Li Hao sighed, continued to scroll down WeChat, and was shocked when he saw the content below.

Because Li Cheng said in the message that he wanted to try to fly above the space-time tunnel with a helicopter and throw a special metal warehouse into the tunnel, which was connected to a steel rope, to see if he could save Li Hao, but before that, he had to use living creatures to do an experiment, because in that expert's inference, it was very likely that there was turbulence in the space-time tunnel, which had strong radiation and power, and was very likely to cause great damage to living beings.

This is a very bold idea, to save people from another world, how can this not shock Li Hao, Li Hao was silent for a long time, and replied with a message, of course, it was Morse code: "Brother, are you there?" ”

After a while, Li Chengcheng replied, it was a voice message: "Yes, Li Hao, are you okay, I haven't heard from you for a long time, but I'm worried about death!" Li Cheng's voice was a little excited.

Li Hao replied: "I'm fine, the message has been received, there is no rush in advance for rescue, my master may have appendicitis and needs surgery." ”

After another minute, Li Cheng replied to the voice message: "Then it's important to save your master first, you wait, I'll go to a doctor friend of mine, ask him to make a set of surgical plans for me, and then take pictures of the surgical plan and send it to you." ”

Li Hao replied: "Without equipment, you can't do surgery." ”

Li Cheng: "Don't panic, I will prepare the surgical equipment immediately, and then throw it into the tunnel, you wait at the exit to see if it can be delivered, if it can be delivered, then you are likely to be able to come back!" ”

Li Hao: "Well, let's try it." ”

After replying to this message, Li Chengcheng didn't reply, probably preparing the surgical plan and equipment for Li Hao.

Li Hao waited for more than three hours, and finally received the pictures sent by Li Cheng, there are so many pictures, dazzling, there are text versions, and there are also picture analysis, Li Hao immediately watched carefully.

Facts have proved that doctors are really difficult to be, no wonder doctors only have master's and doctorate, because it is too difficult to learn medical skills in just four years of college, even if those doctors who graduated with a master's degree have no clinical experience, they are still unreliable, how many times to do an assistant to be the main surgeon, it is a major matter of human life, and there is no room for sloppiness.

Li Hao saw it big, but he had to insist on watching, because this was the only hope to save Zhiyuan Zhenren, Zhiyuan Zhenren was old, and if appendicitis dragged on, it would kill him.

Fortunately, Li Hao has a super memory brain, all the contents are carefully read, you can clearly remember the clock in your mind, when he quickly read all the information, it was the next morning, he sat in the carriage, his brain simulated the operation over and over again, and at the same time took into account all the accidents and solutions mentioned in the surgical plan.

Li Hao didn't know how many times he simulated the operation in his mind, and before he knew it, it was already more than four o'clock in the afternoon, he felt that he could master it, but he didn't know the bottom in his heart, after all, it was just a paper talk now, and medical skills were by no means so easy to learn, and they had to be practiced, not to mention the surgery that required an open abdomen, but unfortunately there was no condition for him to practice it now.

Now he is tired and hungry, thinking that Lu Yun has been guarding outside the mountain pass, he asked Lu Yun to go back to Jingyun Temple to get food, at six o'clock in the evening, Lu Yun brought food, Li Hao decided to believe Lu Yun and took him to the RV.

When Lu Yun saw the RV, he was first shocked, it was the first time he had seen such a huge strange thing when he lived so big, and after entering the RV, he was even more shocked, this was actually a house, and the things in it were so strange, especially the electric lights, he was particularly interested in those electric lights, and had been secretly thinking, this lamp is so big, doesn't it need lamp oil?

Li Hao warned Lu Yun: "Lu Yun, everything you see now is from the fairy world, you must not leak it out, remember, don't tell anyone, otherwise you and I will get into big trouble." ”

"Don't worry, I know what is important." As soon as Lu Yun heard that it was something from the immortal realm, he immediately believed it, after all, the things here were too amazing, and they were not something he could understand at all.

Then the two began to eat, and when they had dinner, it was already dark, and Li Hao had not rested for a day and a night, and he was a little tired, so he asked Lu Yun to rest on the bed on the first floor, and he himself went to sleep in the small bunk on the second floor.

Early the next morning, the first thing Li Hao did after getting up was to charge his mobile phone, and then turned on the phone and waited for Li Cheng's message. ”

Li Hao hurriedly replied with Morse code: "Don't lose the medical equipment first, try to lose something else." ”

Li Cheng: "Okay, I'll send you a message when I arrive." ”

Li Hao: "Hmm. ”

After more than an hour, Li Cheng sent another WeChat message: "Haozi, I'm above the entrance of the tunnel now, I'll drop a shoe and go down, you can see if you can receive it." ”

Li Hao: "Okay, throw it away." ”

Li Hao unplugged the power cord of his mobile phone after replying to the message, rushed out of the RV, and looked up at the sky, if he guessed correctly, the exit of this tunnel should be in the sky, and the height should not be very high, otherwise his RV would have been broken when he crossed over.

Lu Yun saw Li Hao suddenly rushing out of the RV, and he also came out, seeing that Li Hao kept looking up at the sky, as if he was looking for something, he also looked up at the sky.

Suddenly, Lu Yun shouted: "There is something in the sky!" ”

Li Hao was startled when he heard this, looked in the direction he was pointing, and sure enough, he found that there was a black thing floating in the wind at a height of hundreds of meters in the sky, slowly falling, like a slowly falling autumn leaf.

"So tall?" Li Hao was slightly shocked when he saw this, he didn't expect the exit of the space-time tunnel to be so high.

Soon, the black thing was only 100 meters high, and Li Hao also saw it clearly, it was indeed a shoe, but if a shoe fell from the sky, it should be very fast, and it should not be like a fallen leaf slowly drifting, which is very weird.

He thought about it, when he crossed over, the RV should have drifted down like this, so it fell from such a high sky and didn't break, so thinking about it, it naturally made sense, as for what the reason was, he didn't know, maybe it was because of a strong magnetic field, anyway, he was not a scientist, which was not within the scope of his research.

After waiting for a long time, the shoes fell to the ground, due to the effect of the wind, the landing point of the shoes was sixty or seventy meters away from the RV, Li Hao went over to pick up the shoes, and immediately smelled a familiar smell of foot sweat, yes, it was Li Cheng's shoes.

At this time, the mobile phone rang again, and Li Cheng sent a WeChat message: "How about it, the shoes have not passed through the time and space tunnel, anyway, I saw the shoes fall more than a thousand meters here and then disappeared, it's amazing." ”

Li Hao replied with Morse code: "Your feet still stink." ”

Li Cheng: "Haha, that's great, I'll throw the medical equipment down to you." ”

After reading the message, Li Hao looked at the shoes in his hand, and said to himself excitedly: "Great, you can send something over, the master is saved, not only that, but there are many good things in the future world that can be sent over, or ......"

The smile on his face suddenly dissipated, and he whispered, "Or maybe I have a chance to go back...... Back to the restless 21st century......"

If six years ago, Li Hao would have danced with excitement when he thought of going back, but I don't know why, now he can't be happy after thinking of this possibility.

Just when Li Hao was stunned, Lu Yun suddenly pointed to the sky and shouted again: "Look! Something has fallen from heaven again! ”
