Zhang Zheng swore that he had checked everything that could go wrong countless times.

But even if it takes a lot of effort, it can only be made like this.

Looking at the sleeve crossbow in his hand, which was not as good as a toy, Zhang Zheng really couldn't give it to Li Chengqian with a cheeky face.

Picking up the crossbow arrows that fell on the ground, Zhang Zheng installed one of the arrows on several cases like long needles on the machine bracket one by one.

There are a total of six crossbow arrows, and there is one that can be loaded with twelve arrows, but unfortunately Zhang Zheng doesn't know the principle.

Zhang Zheng aimed at a pot of flowers on the windowsill and gently pulled the trigger.

"Huh~"

A cold glow emitted a hollow-breaking sound at a speed that was indistinguishable to the naked eye.

"呲~"

Almost at the same time as the sound of breaking the sky came out, the flower pot on the windowsill came out with a sound of "zig..."

Zhang Zheng walked to the windowsill and looked at the crossbow arrows like long needles.

It did not shoot the clay pot directly like an ordinary crossbow, but stabbed it deeply into the clay pot.

Only one tail wing remains, and it "buzzes" outside the clay pot, buzzing like a sound wave.

I took off the clay pot and looked at it, and sure enough, the other side of the clay pot had been shot through.

Revealing the cold needle.

"That doesn't seem like a bad thing."

Zhang Zheng comforted himself.

Although the range is shorter, there is nothing to pick at this power and accuracy.

Zhang Zheng stretched out his hand to pull out this long needle, which is usually a crossbow arrow, but no matter how hard Zhang Zheng tried.

The crossbow bolt seemed to be fused with the clay pot, and it could not be pulled out at all.

Seeing that he couldn't pull it out, Zhang Zheng didn't bother to drop a clay pot for a needle.

Anyway, it's just a defective product, and there are still five in the sleeve crossbow in his hand, and he will let the king blacksmith make up for it another day.

……

"Xiao Lang Jun, Xiao Lang Jun."

Suddenly there was a panicked call outside the door.

Listening to the voice is Liu Er, the steward of the other courtyard.

"What?"

Zhang Zheng covered the sleeve crossbow less than half a foot long fixed on his arm, opened the door of the study and asked.

"There is a man covered in blood outside the door, saying that His Royal Highness the Crown Prince sent him to see you."

Liu Er saw Zhang Zheng coming out of the study, as if he saw the backbone of the main heart, his panicked expression disappeared in an instant, and he said respectfully to Zhang Zheng.

"Sent by His Royal Highness the Prince, what about the people?"

As soon as Zhang Zheng heard that it was someone sent by Li Chengqian, he hurriedly strode to the front yard.

"I'm waiting in the front hall."

Liu Er trotted all the way to catch up with Zhang Zheng's footsteps.

Hurriedly came to the front hall, and the person who came was Duan Heng, the commander of the prince's personal guard.

Duan Heng's whole body was covered in blood, and at this moment, someone from the Zhangfu Courtyard was bandaging Duan Heng's injuries.

"What the hell, I'm injured."

Zhang Zheng asked with a frown.

Hearing Zhang Zheng's voice, Duan Heng, who was originally sitting on his knees, stood up suddenly, and the little guy who was bandaging his wounds stumbled under his feet.

"Zhang Xiannan, His Royal Highness the Crown Prince was assassinated. The Dispatch will summon you to the East Palace for deliberations. ”

Duan Heng and Zhang Zheng are also old acquaintances, so there is no need to talk so much nonsense at this time.

"What, His Royal Highness the Crown Prince was assassinated. Is the prince injured? ”

Zhang Zheng was shocked, and asked Duan Heng with an anxious expression.

"His Royal Highness the Crown Prince is fine, but three of the brothers of the Prince's personal guard died."

Duan Heng said this, and there was also a look of fear on his face.

Hearing that Li Chengqian was unharmed, Zhang Zheng was relieved.

Commanded Liu Er:

"Go and ask Liu Sanbo to take the brothers with me on a trip to Chang'an."

"Yes"

"Who is the Assassin, and what are the clues? Isn't Cheng Qian in the East Palace, why was he assassinated? ”

Zhang Zheng still had to wait for Liu San to arrive, so he asked.

"His Royal Highness the Crown Prince is ordered by His Majesty to go to the Sifang Pavilion today to comfort the envoys of all parties, and will eventually go with the brothers to protect His Royal Highness the Prince.

When I arrived near Yongning Fang, I heard someone shouting to avenge His Royal Highness the Prince.

The last general and his brothers are wondering, isn't His Royal Highness the Crown Prince good, what revenge is there?

After the other party finished shouting, five assassins rushed out of the houses on both sides of Yongning Fang. They killed three of them in careless manner.

Three of the Assassins were killed on the spot by the Admiral and his brothers, and the other two were captured alive by the Admiral.

Then His Royal Highness the Crown Prince asked me to come to Weinan to summon you to the East Palace. ”

Duan Heng's speech was fast, but Zhang Zheng still heard the cause and effect clearly.

"His Royal Highness the Prince, could it be the person of the hidden prince Li Jiancheng?"

"This, the last general does not know."

The hidden prince Li Jiancheng, at this time in the Tang Dynasty, has almost become a taboo.

Zhang Zheng dared to ask, but Duan Heng didn't dare to answer.

"That's it, let's talk about everything in the East Palace."

At this time, Liu San also arrived, bringing fifty people, and the remaining half of the men continued to stay in Zhuangzi to patrol.

"Your injuries?" Zhang Zheng glanced at Duan Heng and asked.

"It's okay in the end, it's just some skin trauma." Duan Heng replied.

When Liu San heard this, he glanced at this man who was covered in injuries in surprise.

"Let's go, go to Chang'an."

Zhang Zheng didn't say anything more, took the reins handed over by Liu Er and turned over and got on the horse.

Duan Heng followed.

The fifty people led by Liu San were also veterans who were skilled in archery and horses.

Naturally, there will be no shortage of their mounts in the Zhuangzi.

The group got on their horses and hurried towards Chang'an.

There is only a distance of more than 40 miles from Weinan to Chang'an, and it only takes an hour to run a round trip.

Therefore, it took half an hour for Duan Heng to come, a few minutes of delay in Zhang's mansion, and another half an hour to return to Chang'an.

When Zhang Zheng and Duan Heng entered the East Palace, it was clear who had instructed the person who assassinated the prince.

……

The Xiande Hall of the East Palace was once the place where Li Shimin ascended the throne as the emperor.

Now it is the residence of the crown prince Li Chengqian, and since Li Chengqian has not yet taken the concubine, Zhang Zheng naturally has no taboos in the East Palace.

Zhang Zheng stepped into the Hall of Virtue, and what caught his eye was Li Er, who was kneeling on the main seat.

There was also a dignified woman waiting next to her, who was the eldest grandson queen.

Old Li Gang was sitting on the other side, talking to Li Er in a whisper.

And the protagonist of today's assassination, His Royal Highness the Crown Prince Li Chengqian, is the first to be at the bottom.

Next to Li Chengqian sat a woman about the same age as Zhang Zheng, with bright eyes and bright eyebrows.

But it is Li Er's eldest daughter, Princess Li Li, of Changle.

There is also a little fat man in his teens, with two pigtails, a pair of eyeballs rolling around, and a batch of cute ones.

"Uh, Weichen Zhang Zheng, I have seen Your Majesty, I have seen the Queen Mother, I have seen Li Shi, I have seen His Royal Highness the Prince, His Royal Highness Princess Changle, His Royal Highness the King of Wei......"

Zhang Zheng was stunned for a moment, hurriedly saluted, and bowed to His Highness.

Then he glared at Li Chengqian vaguely.

Your family is here, what are you calling me for?

And Li Chengqian responded to Zhang Zheng with a wry smile.

"The little skin monkey is here, this is the East Palace of Chengqian, there is no need to be restrained, sit down."

Li Shimin heard Zhang Zheng's voice and turned his head to look at him.

Then he continued to whisper this to Lao Li Gang, ignoring Zhang Zheng.

On the contrary, it was the eldest grandson queen, who looked at Zhang Zheng with a smile and opened her mouth to give a seat.

"Xie Niangniang."

Zhang Zheng bowed and saluted, walked to Li Chengqian and sat down.

I don't know what the situation is.

Li Chengqian was assassinated, and he hurried from Weinan to Chang'an.

Your family is like no one, what the hell is this?
