Chapter 112 Mercury Fulminate

……

Master Zhu Jiu looked at Wu Wen's serious expression, wondering why he suddenly became so serious.

"This prescription and these things were given to me by Qingyi Hall."

"Qingyi Hall? The Qingyi Hall in Wannian County?" Wu Wen asked.

"Yeah!" Master Zhu Jiu nodded.

"Do you have any connection with them?" Wu Wen frowned.

"No." Master Zhu Jiu shook his head.

"Then why did they give you things?" Wu Wen asked.

"Maybe... it's to please me. After all, your current identity is not ordinary." Master Zhu Jiu guessed with a smile.

Wu Wen took a deep breath.

"I've fallen into a trap!" he whispered to himself.

He then turned around, took the horse, and hurriedly left the yard.

"Awen, where are you going?" Master Zhu Jiu's voice came from behind.

However, Wu Wen had no time to explain and rode away, heading straight for Chang'an City.

Tune the tiger away from the mountain.

Qin Wang Li Shimin was really good at scheming. In order to make his plan successful, he almost eliminated all factors that might affect success or failure.

Wu Wen couldn't help but recall Li Shimin's Xuanwu Gate Incident.

He succeeded in taking power with only a few hundred people, and there seemed to be many coincidences in it, as if it was destiny.

But in fact, there are many inevitabilities hidden behind these coincidences.

This is Li Shimin’s way of employing troops: either do not move and wait for the opportunity to strike; or go out and win, and decide the outcome in one battle.

"Drive~"

After leaving Zhujia Village, Wu Wen rode his horse as fast as he could back to Chang'an City.

However, on the way, he suddenly discovered that the road ahead was full of caltrops.

"Xu~"

Wu Wen stopped his horse and looked vigilantly at the jungle on both sides.

"Come out, don't hide."

As soon as he finished speaking, seven people, three on the left and four on the right, emerged from the jungle and stood opposite Wu Wen.

They were dressed in strange costumes and had different animal masks on their faces, making their identities difficult to identify.

"Mr. Wu, why don't you just stay in Zhujia Village? Why do you have to go back to Chang'an?" A man wearing a dog mask sighed.

"I'll only say this once, get out of the way." Wu Wen said coldly, his hands slowly placed on his waist.

"Hey!" The other party chuckled: "My master has told you that if you insist on returning to Chang'an, you don't have to stay..."

Before he could finish his words, the other party suddenly turned around and waved his arm. A string of darts shot out, half of which rushed towards Wu Wen and the other half rushed towards the mount under him.

Swish!
Wu Wen immediately drew his sword and swung it twice quickly, knocking the dart to the ground.

"kill!"

Following the order from a man wearing a monkey mask, seven people simultaneously threw hidden weapons at Wu Wen, falling as densely as raindrops.

Wu Wen slapped the saddle with one hand, then flew forward, waving the sword in his hand to continuously shoot down the hidden weapons that were shot at him.

however.

at this time.

A hidden weapon that looked like a crystal needle actually caused a huge explosion when it was hit by Wu Wen's sword tip.

Almost in an instant, the sword in Wu Wen's hand was broken, and the powerful shock wave generated at the same time caused Wu Wen to flip several times in the air before he stood steadily on the ground.

It is crystalline and explodes when hit. Is it mercury fulminate?
Wu Wen speculated secretly in his heart and looked at them solemnly.

Mercury fulminate is a primary explosive with extremely unstable properties. It appears as white or gray crystals and will explode violently with the slightest friction.

The production method is very simple. Wu Wen had learned the reaction equation in high school chemistry class. It can be successfully prepared by reacting mercury and nitric acid and then adding ethanol.

Just now, the crystal needle hidden among the many hidden weapons did not cause significant damage to Wu Wen because of its small mass. But if the seven people in front of him each had one and hit him with all of them, the power generated would be enough to make Wu Wen bloody.

So, he had to be cautious now.

"on!"

Following an order from another person wearing a pig-face mask, the seven men stopped shooting hidden weapons at Wu Wenfei and instead took out their weapons and surrounded him from both sides.

Seeing this, Wu Wen couldn't help but raise a smile.

Close combat? That means the move just now was the opponent's trump card, and now it has been used, it may be gone.

Wu Wen stood there waiting for them to approach.

When the seven people came within five meters of him, Wu Wen suddenly rushed forward and stabbed the person closest to him with the broken sword in his hand.

Just as the opponent was about to raise his weapon to resist, Wu Wen suddenly changed his steps, turned his whole body, and flashed from his side to behind him.

The broken sword that was pulled back behind him just happened to slash across his neck, killing him with one blow.

Then, Wu Wen's attack did not stop, he continued to rush towards the two people on the right.

Seeing Wu Wen coming, the two of them immediately coordinated and attacked him.

However, Wu Wen seemed to have the ability to foresee the future and made a judgment in advance to avoid the attacks of the two.

Then, as his figure passed between the two people, the broken sword in his hand took their lives.

In just a breath, three out of seven people died at the hands of Wu Wen.

The expressions of the remaining four people suddenly changed. They no longer formed a scattered siege formation, but gathered together, staring at Wu Wen cautiously, ready to resist him at any time.

Wu Wen looked at the remaining four people sideways. He did not rush forward. Instead, he tiptoed and grabbed the hook-and-sickle spear dropped by one of the three people he had killed, and then inserted his broken sword into the ground.

"Answer me a question and I can spare your life." Wu Wen said as he moved forward.

"What's the problem?" one of them asked nervously.

"Where did you get that explosive hidden weapon?" Wu Wen asked.

"You mean the Explosive Flame Needle? We bought that at Tiangong Workshop." The other party replied.

Wu Wen also knew something about Tiangongfang.

It was a place in Chang'an City that specialized in selling handicrafts, filled with finely carved wooden objects, rolling lanterns, kites and various other toys for the people to enjoy in their spare time.

He had never heard that this place would sell killing weapons like the Explosive Flame Needle.

"Does Tiangongfang sell this thing?" Wu Wen asked doubtfully.

"Of course, ordinary people can't buy it. We only bought one from them at a high price through connections. If it were..."

Before the other party could finish his words, the hand hidden under the weapon suddenly swung out a flaming needle, trying to launch a sneak attack on Wu Wen.

Unfortunately, their every move was exposed once they entered Wu Wen's detection range.

Wu Wen just tilted his upper body slightly to avoid the attack.

Then he turned his wrist and stretched forward, and the hook-sickle spear in his hand rushed towards them like a poisonous snake.

"run!"

At this time, the four of them no longer had the will to fight back and wanted to flee in all directions.

But how could Wu Wen give them this opportunity?

With his other hand, he slapped the gun body, and the tip of the hook-sickle gun swung like a snake's head, cutting off their heads one by one like harvesting weeds.

bang~
As the explosive fire needle flew away and landed with a roar, the battle came to an end.

Wu Wen took a few steps forward and searched their bodies with the tip of his gun. He found that the explosive needles on their bodies were indeed gone. He couldn't help but shook his head with regret.

He put away his gun and turned away.

Wu Wen came to the fallen horse.

In order to avoid the shock wave of the explosion, he did not block all the hidden weapons, so the horse was hit by four or five hidden weapons. Although it was not fatal, it made it unable to move.

"Ugh!"

There was no time to care about it. Wu Wen sighed lightly, then left it behind and quickly rushed to Chang'an City alone.
