On the other hand, Rong Zhen in the Northern Frontier was seriously injured and fell into a coma.

Perhaps no one would have thought that after the Northern Frontier Army suppressed the Jie people for a whole month, they would be defeated by the counterattack of the Jie people, and all of this was due to the secret weapon possessed by the Jie people.

The iron balls that could emit a huge noise and spray fire were fired by the Jie people with a long chimney-like thing. As long as they fell into the crowd, they would blow people into a bloody mess.

Although Rong Zhen retreated in time after realizing that something was wrong, the Northern Frontier Army still suffered heavy casualties, and even the commander Rong Zhen was seriously injured. The battle report for help had been sent back to Yanjing, but it was too late to save the situation.

The camp was a horrible scene. Soldiers with black and gray faces sat in the open space in despair. Blood and broken limbs could be seen everywhere. The comrades who had been drinking and bragging together yesterday were separated forever after just coming into contact with the Jie army. Not only ordinary soldiers found it hard to accept, but even many officers with high ranks were at a loss.

At this moment in the main tent, Rong Zhen's eyes were tightly closed, and beads of sweat dripped from his red face. The outside of his thigh was stained red with blood, and many small fragments could be vaguely seen in the bloody wound. The military doctor used a gold needle to temporarily stop the bleeding for him, and then clipped out the fragments bit by bit.

Song Zhiyi's face turned pale. Rong Zhen would not have been injured originally. It was because he tried to save him that he was injured by that strange thing. Now seeing Rong Zhen lying on the bed, he didn't know whether he was dead or alive, he wished he could die immediately. He asked Nie Zhishu tremblingly: "Cousin will be fine, he will be fine, right?"

Nie Zhishu's face was also serious, but he nodded vigorously: "Yes, the master is blessed with a long life. He has suffered a lot of injuries over the years, but he can survive!"

Song Zhiyi murmured as if he had grabbed a life-saving straw: "Yes... yes... he can survive... can..."

Although Nie Zhishu was also anxious, seeing Song Zhiyi's useless look, he couldn't help but grabbed his collar with bloodshot eyes and roared: "Song Zhiyi, listen carefully, what you have to do now is to quickly find out what that thing is "What? Don't wander around here like a headless fly!"

Song Zhiyi seemed to come back to his senses after being yelled at. He gasped twice and forced out a sentence from his teeth: "You are right, these despicable coyotes, I will make sure they die without a burial place!"

Nie Zhishu wanted to say something else, and then he saw the military doctor shaking his head and slowly walking over. Both of them were heartbroken and rushed over: "What happened?"

The military doctor's surname was Mao. Although he was only in the Northern Frontier Army, he was actually a doctor with very high medical skills. However, he frowned and said: "Everything in the wound has been taken out, but looking at your appearance, it is clear that you have been poisoned by fire. This is difficult to deal with."

"Doctor Mao, just tell me what medicine you need, and I will find it for you even if I have to go to heaven and hell."

Military Doctor Mao sighed: "Medicine is secondary, but this fire poison is really tricky. Your Highness's injury seems not serious, but it is very troublesome to treat. If Your Highness is not strong and has martial arts skills, I am afraid you will not be able to survive for three days. Now, I can only do my best."

Upon hearing what he said, Song Zhiyi's eyes suddenly turned red, and he was about to go out without saying a word, but was stopped by Nie Zhishu: "Where are you going!"

Song Zhiyi gritted his teeth: "I'm going to kill those coyotes!"

"Don't make trouble!" Nie Zhishu resisted the urge to beat him and said in a low voice, "Going into battle to kill the enemy is my job. You are the leader of the Night Owls. What you need to do is to find out what those things are and the current military information of the Jie people. As for the rest, wait until the master is well!"

Song Zhiyi's fists clenched so hard that they made a "clucking" sound. He knew that what Nie Zhishu said was right, but the hatred and regret in his heart were about to burn him to ashes. He hated the Jie people, and hated himself even more. His cousin had clearly said that the Jie people's behavior was abnormal and asked him to be extremely careful, but not only did he not help him, but he also caused him to get hurt because of him. Thinking of this, Song Zhiyi just wanted to punch himself hard.

Nie Zhishu saw that he had not come to his senses after hearing what he said, and was still on the verge of losing control, so he simply knocked him out with a slap, to prevent him from doing anything stupid again without him noticing.

After doing all this, Nie Zhishu walked out of the tent and said to Zhuque who had been waiting outside: "What's going on outside now?"

Zhuque was also the deputy commander of Yexiao, but compared to Qingluan who won with combat power, he was better at brainpower. Rong Zhen's injury this time also made him feel particularly guilty. Hearing Nie Zhishu's question, he quickly replied: "Fortunately, we retreated in time, and the number of injured people was not too large, but the morale dropped sharply, and I'm afraid we won't be able to fight in a short time."

Nie Zhishu's eyebrows surged with murderous intent, and he said in a vicious voice: "What the hell is this!"

Zhuque said: "The spies reported that the Jie people called this thing Huo Pili, and no one knew when this thing appeared, but the news from the imperial court said that it was given to Su Yiwuya by a mysterious person."

"Who is that mysterious man?" Nie Zhishu asked hurriedly.

Zhuque shook his head: "The place where that person lives is surrounded by heavy guards. Our people only saw a silhouette from a distance. We only know that it is a master and a servant, both men, and we don't know anything else."

Nie Zhishu said: "Now that the master is injured, there can't be any mistakes in this camp. Qingluan is very powerful, and he must guard the master so that I can do what I want."

Zhuque nodded: "If something happens, I will I have already sent a letter to Qingluan. If he works day and night after receiving the letter, he should be able to arrive within 20 days. "

Nie Zhi sighed and said to himself: "What exactly is this Huo Pili? Why have I never heard of it..."

In fact, if Lu Zheng was here, he would be shocked, because this so-called Huo Pili is so familiar to modern people that it is gunpowder, one of the four great inventions of ancient China.

However, Lu Zheng did not know that Rong Zhen was in danger. At this moment, he found an important clue from the information brought back by Bao Zheng.

Hang Jue made up his mind to be a hands-off manager and responded to Lu Zheng's requests. Although the case files could not be borrowed, he sent several clerks to copy them overnight, and Bao Zheng sent them back at full speed.

After Lu Zheng got the letter, he finally knew the whole story. Why did the county lieutenant attack Jiang Wenchang's stronghold? It was because of a letter from Jin Hanxuan. Even the smooth attack process was also related to Jin Hanxuan. All this happened after the two elders of the Jiang family were killed.

Now the question is, Jin Hanxuan killed Chai Shuang and Jiang Wenchang. What was he trying to cover up? What was the inside story of the murder committed by the red-clothed thief? And what role did Jiang Sanniang play in this?

Lu Zheng sighed and had to come to Jiang Sanniang's tofu shop again. After listening to his story, Jiang Sanniang's face changed several times, and finally said sadly: "My lord has really found out about this..."

Lu Zheng said sharply: "Is there anything else you haven't told me?"

Jiang Sanniang sighed: "Now that things have come to this, I can only tell you the truth. My surname is not Jiang, but Jiang."

Lu Zheng widened his eyes: "Then... Jiang Wenchang is yours..."

"He is my brother." Jiang Sanniang laughed at herself. "My real name is Jiang Wenshan. My master killed my whole family. I was young and fainted from fear. When I woke up, I didn't remember what happened. So he adopted me and made up a lie to deceive me. It's ridiculous that I actually regarded the real murderer as my benefactor and never doubted him. I am really stupid."

“My elder brother went to study abroad that year, and found out his family had been destroyed when he returned home. He tracked the red-robed thieves all the way to Qingxi County, and recognized me, but was afraid of being discovered, so he asked Chai Shuang to get close to me. However, no matter how careful we were, we were still discovered, and Chai Shuang escaped overnight. The two old guys were afraid of my revenge, so they also escaped, but were still caught by my elder brother. Unfortunately, they didn’t know why the red-robed thieves wanted to kill our entire family, so my elder brother could only kill them to comfort our parents’ spirits in heaven.”

Speaking of this, Jiang Sanniang showed a sad look on her face: “I didn’t expect Chai Shuang to be found by them. I felt something was wrong at the time, and wanted to persuade my elder brother to leave here together and start a new life, but I didn’t expect that I was too late, and my elder brother I was caught and killed as the leader of the gang. I know that it must be that group of people who did it. I don’t know why they didn’t kill me together, but I must kill them and avenge my family! "

Jiang Sanniang wiped the tears from her face and said to Lu Zheng: "I know that you are very capable, since you can find out all the way here, I think you can find out who that group of people are. As long as you find out, I am willing to work hard to repay you."

Lu Zheng felt very uncomfortable. He could not think that there was such an inside story in this matter, but now he could not tell Jiang Sanniang the identity of the other party, because he still needed to find out the real reason why the Jiang family was wiped out.

Lu Zheng had a hunch that this was the most important and critical part of this series of cases. As long as we know this, I am afraid that the huge mystery in this case will be solved.
