"Zhou Tingshi, Wang Xianling, and father-in-law, you don't have to send it anymore! Let's go back! ”

Lanzhou.

In less than three days, the locust plague here was completely wiped out by the Tianji Brigade, and after breakfast, Li Zexuan took the children to set off again, planning to go directly to join Li Ke and Cheng Chumo in the east!

Zhou Wenfang, Wang Chengxing and other officials who rushed to hear the news personally sent them to a long pavilion ten miles away in Yifang County.

To tell the truth, he doesn't like others to send him, because it affects their itinerary too much, if no one sends it, he and the children at least ride horses, ride bicycles, and it is estimated that they have already left Yifang County at this time!

"That being the case, please take care of Master Hou! Xiaguan for the 360,000 people of Lanzhou, thank Hou Ye for his life! When he comes to Lanzhou again, the people of the state will be welcomed! ”

Lanzhou Assassin Zhou Wenfang bowed deeply to Li Zexuan.

"Thank you for the grace of your life! Welcome to Lanzhou again! ”

The people on the side of the road shouted somebody, and the rest of the people also shouted:

"Thank you for the grace of your life! Welcome to Lanzhou again! ”

Today, it is not only the officials of the state capital who came to bid farewell to Li Zexuan, but also the people of Lanzhou, these children brought by Li Zexuan in the past few days, leading the Tianji Brigade to sweat like rain in the fields and eliminate locusts, the people are all in their eyes and in their hearts. Now that Li Zexuan and the children are leaving, how can they not come to send them off?

As a result, both sides of the pipeline from Yifang County to Jingle County in the east are densely packed with people who came to see them off, mighty and endless, not to mention more than 100,000 people!

More than 100,000 people shouted a word together, how majestic was that? It is not an exaggeration to describe it as shaking the earth.

Li Zexuan originally wanted to say a few words of parting to his father-in-law, but it was so noisy that it was definitely impossible to say goodbye, so he could only wave his hand and not take away a cloud, and then he turned over and rode towards the east with the children.

"Dididi!"

It took nearly half an hour for the "big army" led by Li Zexuan to finally walk out of Lanzhou, and at this moment, there was a sudden sound of "Dididi" in the wooden box carried by a child not far from him.

"Young Master! The telegram is coming! ”

When the child heard this sudden "Didi" sound, he couldn't help but feel excited, and hurriedly jumped off the bicycle and ran towards Li Zexuan with the box on his back.

At the beginning, the telegraph was under the management of Li Ke, but since they were divided into two ways in the Xianyang army, Li Zexuan handed over the telegraph to the management of his team of children, he selected sixteen strong children, each of whom took turns to manage the telegraph for half a day, and the children only needed to notify him when the telegraph rang!

"Go and talk to Uncle Hu, everyone find a shady place to rest, and we'll set off again in two quarters of an hour!"

Li Zexuan turned over and dismounted, took the telegraph from the child's hand, and gave a casual order, and then he saw that there was a boulder next to him, so he put the wooden box on the boulder, and took out the telegraph and put it on the box.

"Yes! Master! ”

The bear child answered, and then ran away.

Li Zexuan "listened" to the telegram intently.

As the academy's telegraph technology becomes more and more mature, when telegraph communication, a set of specifications has gradually formed, the code is a test response code at the beginning, there is not much substantive content, just to wait for the other party's answer, and confirm the identity of the other party, and then the other side of the transmitter will send a formal message!

In this way, firstly, the receiver can avoid missing the first message, and secondly, the security of telegram transmission can be increased more or less!

"Roger, Yanhuang 001!"

After putting the telegraph away, Li Zexuan quickly sent a message.

Yanhuang 001 was a temporary code name for him, and besides, he didn't have to refer to the codebook to send telegrams now, because those things were already in his head.

After about half a cup of tea, the telegraph finally rang again.

Li Zexuan closed his eyes, and those "tick-tock" messages of different lengths quickly converted into Chinese character information in his mind after passing through his ears:

"Mountain chief, Jin Wanfu made false accounts, causing 30,000 yuan in Yanhuang Qianzhuang in Xinfeng County to disappear! During the arraignment in Dali Temple, Jin Wanfu died violently in prison the night before yesterday, with no injuries in his body, no poison in his body, and a bizarre death! Now Tai has some clues, suspecting that Jin Wanfu was stabbed in the back of the head with an ice needle in his mouth, but he doesn't know where the murderer got the ice needle, and the case cannot be conclusive. Very urgent! ”

In the message, Li Tai told Li Zexuan about the Jin Wanfu case in a few words, and told Li Zexuan about some "very urgent, online and waiting" stalks.

After recovering from his contemplation, Li Zexuan began to send a telegram: "Saltpeter is soaked in water, it absorbs heat and cools down, and the water can become ice!" ”

Subsequently, Li Zexuan added, "Have you found the real murderer who killed Jin Wanfu?" ”

Regarding the method of saltpeter ice, he doesn't plan to hide it all the time, this thing can't be hidden for a lifetime, anyway, he entrusted his own family last year, and his father bought a few saltpeter mines, even if the rest of the people know that saltpeter can make ice, then he holds saltpeter mines, and it is not a loss!

Chang'an City, Dali Temple, after translating the code sent by Li Zexuan into words, Li Tai was ecstatic and said: "Someone! Go to the nearest pharmacy and buy some saltpeter for the king! ”

"Yes! Your Highness! ”

A servant looked at Liu Dewei, and after seeing him nodding slightly, he hurriedly clenched his fists and said.

"What did King Wei do when he bought saltpeter?"

Dai Xuan frowned and couldn't help but ask.

"Dai Shaoqing, wait a moment!"

Li Tai didn't have time to answer Dai Xuan's question at this time, because he wanted to reply to Li Zexuan's telegram.

"Regarding the identity of the murderer, Zhixun and I have already mastered some evidence, this person's identity is special, it's a long story, after the people of Tai Gang Dali Temple solve the case, we will talk to the mountain chief in detail! At that time, there are still some things to ask the mountain chief for! ”

"Dididi~Didi!"

Seeing that Li Tai skillfully operated the telegraph machine, but did not answer his own question, Dai Xuan was rarely not angry, but became interested in the telegraph in front of Li Tai in his heart. Li Zexuan is now in the northwest of the empire to provide disaster relief, everyone knows about this matter, but with such a long distance in between, it is amazing how amazing it is to be able to transmit information in "real time"!

Dai Zhou had also heard of the telegraph before, but as the saying goes, it is better to be famous than to see it, and only when you see it with your own eyes can you feel the shock!

"Dicterson? Could it be that Di Zhixon is helping Li Tai solve the case? ”

On the other end of the telegram, Li Zexuan couldn't help but mumble to himself in a low voice after receiving the news.

Di Renjie Everyone knows that Li Zexuan didn't know how many movies and TV shows of "Detective Di Renjie" in his previous life, but he didn't think that Di Renjie's father Di Zhixun actually had the talent to investigate cases!

Lao Di's family is full of the talent of investigating cases!

Dali Temple.

After sending the telegram, Li Tai had a moment, he stood up, looked at Dai Xuan and said: "Dai Shaoqing don't be impatient, when the official returns, this king will show you how to make ice in the summer!" ”

"Xiaguan will wait and see!"

Dai Xuan withdrew his gaze from the telegraph, then arched his hand and said.

Time passed slowly, and after a while, the official bought back a small bag of saltpeter and handed it to Li Taidao: "Your Highness, the saltpeter you want!" ”

"Hmmm! Stand down, all of you! No one is allowed to enter this courtyard without the king's command! ”

Li Tai stretched out his hand to take the saltpeter, and then said in a deep voice to the officials around him.

Andy Lau is an old man, and he knows that Li Tai doesn't want to leak out the ice-making method, so he waved his hand and said, "Listen to Your Highness, you all retreat!" ”

"Whoa!"

More than ten officials in the courtyard hurriedly withdrew from the courtyard gate when they heard this.

Dai Guan, Liu Dewei, Sun Fujia, as well as Sun Zifan, Di Zhixun, and Wei Chi Baolin, all set their eyes on Li Tai, wanting to see how he made ice in the summer!

I saw Li Tai get a basin of water, and got a wooden bowl, the wooden bowl was filled with a small half bowl of water, the wooden bowl was placed in the basin, because the density of the wooden bowl was small, and it was not filled with water, it floated on the water, Li Tai took out the saltpeter at this time, and gently put it into the basin, and saw that the saltpeter quickly released bubbles, and gradually, a shocking scene appeared, the water surface of the basin began to condense into ice, and with the passage of time, the ice became thicker and thicker, and finally the water in the wooden bowl also condensed into ice!

Dai Xuan and the others looked stupid next to them, they couldn't say a word, Li Tai's heart was of course also shocked, after all, this was the first time he used saltpeter to make ice, and he didn't have much bottom in his heart, but now that the ice was successful, he breathed a sigh of relief at the same time, and his admiration for Li Zexuan was a little more!

"Huh! Dai Shaoqing, how's that? Is this a summer ice-making? ”

Li Tai took out the water basin from the wooden bowl, and then he handed it to Dai Xuan with half a bowl of ice, and said with a smile.

"Goo-dong!"

Feeling the slightest coolness coming from the top of the wooden bowl, Dai Zhou couldn't help but swallow his saliva, and then arched his hand and said, "Count!" Absolutely! His Royal Highness's talent is beyond the reach of others, and his subordinates admire him! ”

Li Tai smiled with satisfaction, and then said, "I didn't come up with this ice-making method, it was told to me by the mountain chief!" To be honest, this method is the unique secret method of the mountain chief, and now because of the murder case, the mountain chief has dedicated it, Liu Siqing and the two Shaoqing are both people of noble character, presumably they will not pass on the secret method, right? ”

This can be regarded as a reminder, and it can be regarded as a beating, Li Taike is not only a student of Yanhuang Academy, but also the current King of Wei!

Liu Dewei solemnly arched his hand and said: "Your Highness, rest assured, today's matter, the three officials will never mention it to anyone!" ”

"Exactly!"

Sun Fujia and Dai Xuan all nodded along with him.

Li Tai smiled and continued, "Hehe! Since several people believe that ice can be made in summer, then this case is almost over! ”

Dai Xuan hurriedly said: "Your Highness's words are wrong! Even if the murderer used saltpeter to make ice and killed Jin Wanfu with an ice needle, we still don't know who the murderer is? How can this be closed? ”

Di Zhixon took over the conversation at this time and said: "As for who the murderer is, the younger generation may know!" ”

"You know?"

Dai Xuan frowned, a little unconvinced.

Di Zhixun said in a deep voice: "The murderer is the Heavenly Dragon Sect Venerable Doom Divine Monk!" ”

As soon as the word is uttered, everyone is shocked!

Liu Dewei, Sun Fujia, and Dai Zhou all looked shocked, Dai Guan's eyes widened in disbelief, and asked, "Doom?" Di Gongzi, the case can be judged by evidence, the Tianlong Sect has recently flourished in Chang'an City, attracting a lot of people, if Du Er is really a murderer, then the government wants to arrest him, but it will cost a lot of trouble! ”

"Of course I have proof!"

Di Zhixun said with a serious face: "Just recently, the monk Du'e preached Buddhism in front of the Daxingshan Temple in Chang'an City, and performed immortal arts. This shows that Du Er is proficient in the method of ice making, and the dead Jin Wanfu was stabbed to death with an ice needle, isn't this coincidence enough to determine that Du Er is the real murderer? ”

"Turn a bottle of flowing water into ice in an instant? How did he do it? ”

Sun Fujia was a little puzzled.

Li Tai replied: "We don't know about this! But in any case, it is feasible to make ice in the summer,"

Di Zhixun said in a deep voice: "The murderer is the Heavenly Dragon Sect Venerable Doom Divine Monk!" ”

As soon as the word is uttered, everyone is shocked!

Liu Dewei, Sun Fujia, and Dai Zhou all looked shocked, Dai Guan's eyes widened in disbelief, and asked, "Doom?" Di Gongzi, the case can be judged by evidence, the Tianlong Sect has recently flourished in Chang'an City, attracting a lot of people, if Du Er is really a murderer, then the government wants to arrest him, but it will cost a lot of trouble! ”

"Of course I have proof!"

Di Zhixun said with a serious face: "Just recently, the monk Du'e preached Buddhism in front of the Daxingshan Temple in Chang'an City, and performed immortal arts. This shows that Du Er is proficient in the method of ice making, and the dead Jin Wanfu was stabbed to death with an ice needle, isn't this coincidence enough to determine that Du Er is the real murderer? ”
