As soon as Rong Zhen and Lu Zheng arrived at the border town, Song Zhiyi and Nie Zhishu came to greet them with a large group of guards. It was no wonder that they mobilized so many troops. When Rong Zhen said that he would go to Guning County to pick up Lu Zheng, the two generals were really shocked. They were also old men who had followed Rong Zhen for many years. They knew that this master was always cold-hearted and had never seen him care so much about someone. So this time the two of them came to pick him up, and they also wanted to see if their own prince had taken care of the future princess.

The result was naturally disappointing to the two.

When they arrived at the border town, Rong Zhen and Lu Zheng changed carriages. Compared to the carriage on the road, this carriage is obviously much more luxurious, but it is obvious that this carriage is not often used by Rong Zhen. Lu Zheng can even smell the smell of tung oil that has not completely dried on the carriage. In fact, if you think about it, you will know that Rong Zhen, as a military commander, has always ridden a horse. This border town probably has no carriages prepared. This carriage should be made temporarily because he was injured.

But Lu Zheng guessed wrong. This carriage was specially prepared for him. Rong Zhen is not a person who cares about enjoyment, and he has been on the march for many years. If it weren't for this tender little master, why would he bother to order a new carriage?

Outside the carriage, Song Zhiyi frowned and whispered to Nie Zhishu: "Did you succeed or not? Why can't I tell?"

Nie Zhishu sneered: "Being the leader of the Night Owls is really a waste of time for you, Lord Song. In this case, it would be more appropriate for you to be the mother of Nanfeng Pavilion."

Song Zhiyi was not angry at this, but looked at Nie Zhishu with a teasing face: "Okay, big guy, you have been bad in Yanjing for a short time, even Nanfeng Pavilion knows it. Tell me, you like coquettishness to the bone, Still pure and lovely?"

Nie Zhishu's face darkened: "What nonsense!"

Song Zhiyi laughed: "You are not good enough to anger me, but you are far worse than my cousin."

At this moment, the curtain of the carriage was opened, revealing Rong Zhen's cold face, and he nodded to Song Zhiyi.

Song Zhiyi went over in a hurry and asked, "Cousin, what do you want me to do?"

Rong Zhen said indifferently, "Go to Huaishu Lane to buy some food, and then go to Yong'an Lane to buy some wine."

Song Zhiyi's eyes lit up, "But Master Lu wants to eat?" But then he became puzzled, "The wine in Yong'an Lane is indeed good, but the food in Huaishu Lane is not up to standard. Wouldn't it be better to go to the Yuelai Restaurant next to Yong'an Lane to buy it?" The most important thing is that these two alleys are one in the south and one in the north, and the distance between them is quite far.

Rong Zhen didn't even raise his eyes: "Did I say I bought it to eat?"

"Huh?"

"You're too noisy. This comes and goes just enough to help you clear your head."

"!!!"

Nie Zhishu had long been unable to bear and started laughing loudly at Song Zhiyi. Looking at Song Zhiyi's face, which was filled with anger but unable to speak, Nie Zhishu's original resentment was swept away, and he immediately felt refreshed.

At this moment, Rong Zhen turned his gaze to Nie Zhishu: "Zhishu, you go with Zhiyi."

"Huh?!"

This time the person who laughed at him became Song Zhiyi. He didn't care about the punishment anymore. He hooked his arm around Nie Zhishu's neck with a smug look on his face: "General Nie, just accompany me for a trip."

Nie Zhishu glared: "Take your claws away!"

Song Zhiyi knew when to stop and looked up at the sky: "Let's hurry up, otherwise we won't be able to have lunch. I don't think my cousin will ask the kitchen to leave any food for us."

"Stop talking nonsense! I'm all because of you."

The two left noisily.

Rong Zhen then lowered the curtain and said to Lu Zheng, "Okay, everyone who's having fun has been driven away, why don't you sit closer?"

Lu Zheng was a little helpless. How could he not realize that His Royal Highness the Prince of Chu was so childish? He couldn't help but ask, "What did you say to them? Why do they look at me so strangely?"

Rong Zhen took the teapot off the stove, poured a cup of tea for both of them, and said, "Oh? Then this punishment is a bit light."

"Hey!"

Rong Zhen handed the tea to Lu Zheng and said softly, "We need to teach them to be more modest. How can they keep staring at the future princess?"

After such a long time, Lu Zheng almost forgot how good the Prince of Chu was at flirting. He was a novice and could not compare to the experienced driver. So when the carriage arrived, he quickly jumped off and rushed into the mansion.

Rong Zhen couldn't help laughing in the carriage. He really didn't like Song Zhiyi and the others looking at Lu Zheng as if he were a novelty, but Lu Zheng's performance really made him feel very cute. He had heard the story of loving the house and loving the dog in it when he was young. He thought that with his cold and rational personality, he would never meet a person in his life who could let him let down his guard and like, let alone love. But fate has its own destiny, and he couldn't escape it after all, but he didn't dislike this arrangement of fate, and he would only accept it with joy.

Rong Zhen got off the carriage and told the housekeeper to find Lu Zheng, but he came to the study first.

In the study, Su Dai was waiting there. Seeing that only Rong Zhen came in, Su Dai was a little confused: "Didn't Lord Song and General Nie go to greet you? Why haven't they come back yet?"

Rong Zhen said lightly: "They behaved frivolously, and the king asked them to go out in the sun to clear their minds."

Su Dai couldn't help but smile. He was naturally curious about who could impress this master, but after all, he was older and more mature, and he wouldn't be as nonsense as Song Zhiyi and Nie Zhishu. Hearing how Rong Zhen was protective of Young Master Lu, Su Dai had an idea in his mind, but he did not ask without proper consideration. Instead, he changed the subject: "I have received a letter from Marquis Jian. He will arrive at the border town in about a day. I wonder how Your Highness will place him?"

This sentence was certainly not asking where to let Jian Yu live, but asking Rong Zhen what attitude they should have towards Jian Yu.

Rong Zhen had said these words to Qingluan before, but now he said them again to Su Dai, but the meaning was much deeper: "The situation in Yanjing is unclear now, and it is not appropriate for us to show up at this time. As for this Lord Jian, I have dealt with him in Yanjing before, and he is also full of tricks and schemes. He jumped from guarding the imperial mausoleum to becoming the commander of an army. I don't believe that this was your majesty's idea. He came to the northern border this time to get credit, and before we know how many cards he has left, we should , and I am not willing to be his enemy."

Su Dai said again: "Will he pose any threat to Your Highness?"

Rong Zhen shook his head: "Now that the Wei Wang's party has revived, and since he has established a connection with the Wei Wang, the person he should be careful of is not me, but the current emperor. I think he also understands that I am not willing to be his enemy, so why would he be willing to provoke me?"

Su Dai breathed a sigh of relief: "Since Your Highness said so, I know what to do."

"There is no need to let him go too smoothly." Rong Zhen pondered, "There may be spies in his team. Although I am willing to give him the credit, I don't want to get involved in those things. You should be more sensible and don't delay the business."

Su Dai understood and mentioned another thing: "I have seen that the Fire Thunderbolt has many shortcomings, but its power is not weak. Can you let Lord Song pay more attention to this matter? Although it cannot be used for attacking the city in the future, it is very effective in defending the city."

Rong Zhen shook his head: "If the King of Wei dares to release this kind of thing, he will not let the Jie people learn it. Since Jian Yu is so confident, I guess there are not many such things in the Jie people. There is no need to waste manpower and resources on this matter. On the contrary, we have found some other things in Guning County this time."

"Oh?" Su Dai was a little disappointed at first, but he was refreshed when he heard Rong Zhen say that: "I wonder what it is?"

Rong Zhen paused: "This thing is called petroleum, it will burn when it comes into contact with fire, and it cannot be extinguished even with water."

Su Dai was surprised: "There is such a thing!"

In fact, on the way, Lu Zheng also talked to Rong Zhen about some uses of petroleum, and he quickly told him how to make a homemade incendiary bomb.

Boys usually talk about military football or games when they are together. Lu Zheng has a roommate in his university dormitory. Yes, he is the scumbag who pretended to be gay to dump girls mentioned in the previous article. He is very familiar with the military and can name most of the weapons. His greatest achievement is that he actually invented an "incendiary bomb" when he was at home during the winter vacation.

Of course, this thing is not wine, but a common weapon used by guerrillas and other irregular forces and street rioters. It is also another name for homemade incendiary bombs.

When everyone was at the night talk, everyone was very interested in this, so this person enthusiastically told the process, and Lu Zheng naturally remembered it.

On the way back to the border town from Guning County, Lu Zheng and Rong Zhen were chatting in the carriage, and they talked about oil. In our modern society, oil is closely related to our lives. Whoever has an oil field controls the global economic artery! Look at the local tycoons in the Arab region, and then look at the US-Iran war back then, it was all caused by oil.

Of course, in this ancient time when even the steam engine had not been invented, even if there was oil, it was useless, which also put an end to Lu Zheng's dream of getting rich overnight. However, he still talked to Rong Zhen about some uses of oil in modern society with a nostalgic mood. He was so excited that he said, "What is Huo Pili? It feels like gunpowder made by native methods. In history, oil can also make equally awesome weapons!"

Lu Zheng forgot about these things, but Rong Zhen remembered them in his heart. Although he had not yet planned to really verify the incendiary bombs mentioned by Lu Zheng, he still sent people to surround the back mountain. Now that Su Dai mentioned Huo Pili again, Rong Zhen revealed some of it.

Su Dai walked back and forth excitedly: "Your Highness, if you have this thing, the destruction of the Jie people is just around the corner."

Rong Zhen shook his head: "This thing, I don't intend to use it against the Jie people."

Su Dai was stunned: "Why?"

"The Jie people are already like grasshoppers after autumn, they can't jump for two days." Rong Zhen said lightly, "Compared to destroying them, I am more concerned about how they got in touch with the King of Wei under our heavy surveillance."

"Could it be... there is a traitor?"

"Not necessarily an traitor." Rong Zhen lowered his eyes, "I'm afraid that the King of Wei still has methods that we don't know about. This is the most important thing."

Su Dai asked doubtfully: "Your Highness is worried that the King of Wei..."

"Although they are very capable, my nephews are useless. Although the government is relatively stable now, the King of Wei has been lurking for so many years. Since he chose to show up at this time, how can people believe that he has no intention of taking that position?" Rong Zhen frowned slightly. "But I have seen that the methods he has used repeatedly in the past six months are really strange, which makes people unsure of his intentions."

Su Dai has been dealing with the war in the border town and has no interest in Yanjing. Although he was not very clear about what happened, he still said, "Your Highness, why shouldn't you know? The King of Wei clearly regards you as a thorn in his side. Aren't all these things directed at you? It can be seen that in his heart, those princes are not as threatening as you."

Rong Zhen shook his head, but did not explain further. In fact, as he explored the old case twenty years ago, he felt that the fog was getting thicker and thicker, and at the same time, he became more and more curious about the King of Wei.
