In 1669, a German named Blount created a new substance in the shape of white wax by mixing and heating human urine with sand and other substances, which was white phosphorus.

White phosphorus has a strong irritation, its smell is similar to that of garlic, the ignition point is very low, only 40 °C, it is easy to burn once it comes into contact with oxygen, emitting a yellow flame while emitting a strong smoke.

Later, white phosphorus was used in warfare, and when aluminum powder and viscous agents were added to support combustion, it became an extremely bloody and cruel white phosphorus bomb.

Although the technical content of the white phosphorus bomb is not high, it has a very powerful combustion effect, which is not only difficult to remove when stained with the skin, but also has a burning temperature of more than 1000 °C, which can quickly burn the soft tissues, and then burn the bones deeply, and at the same time produce a huge amount of irritating smoke, and the killing process is efficient and cruel.

Because the white phosphorus bomb is so cruel that it is even banned by international conventions, but because its lethal effect is so good, many countries ignore the ban and still use it in large quantities.

Xu Rui made white phosphorus in the same way, stored it in the thermal insulation layer of the Eight Treasure Medicine Chest, and the surface of the map and wooden sign were coated with white phosphorus mixed with aluminum powder, and then sealed with a thin layer of wax to keep out the air.

The pellet is simply a white phosphorus bomb with aluminum powder and syrup (a viscous accelerant) and then sealed in wax.

In order to confuse the dark chess, he deliberately left the secret chess code in the cave, which was originally just a trick to fake a shot, but when he was caught by Lu Kang, the wicker inserted by his hand had a great effect.

Xu Rui knew that after he disappeared, the dark chess would never let go of any clues, even if there was no dark chess ambush on the writing tower, there would definitely be someone watching him, as long as he made some movement, it might cause the idea of the dark chess.

If the dark chess really finds here, and the two sides make a big move, he will have the possibility of profiting from it.

Lu Kang and his gang naturally didn't know Xu Rui's plans, so they sent someone to Wenbi Tower with three tokens to find Tianmen.

By the time the three old peasants followed his instructions and exposed the three things to the sun at noon in the middle of summer, the thin layer of wax began to melt gradually, and once the white phosphorus came into contact with the air, it would spontaneously combust, creating this horrific massacre, thus attracting the attention of Dark Chess.

It was a risky plan, and any failure in any of them could lead to Xu Rui's death, but maybe his luck was good, at least so far, everything was still under his control.

In the ruined temple outside Daxing City, Bai Xiaohan unfolded the flying pigeon biography he had just gotten, and was suddenly shocked.

She quietly tore up the note, her eyes swept over the dozen injured dark chess pieces.

Xu Rui's sudden disappearance made them have to take a huge risk to sneak back to the city to find out the news, but they didn't expect to meet Li Kuang, which instantly pierced her disguise and caused a fierce battle.

Fortunately, she and Yaoli are both first-class masters, and they suddenly attacked under the surprise of the other party, and finally barely broke through after killing and injuring dozens of lives.

It's a pity that Li Kuang made great achievements, and immediately fled when he saw that the situation was not good, and then found reinforcements to pursue them as soon as possible, in order to cover her escape, the remnants of the dark chess lost a lot.

At the moment, except for a very small number of kites with broken strings, these dozen remnants of the defeated army are the last strength in her hands.

"These dozen lives can at least hold the officers and soldiers for a while, so let them play their final value."

Bai Xiaohan made a cruel decision in his heart, got up and said to the left and right: "There are officers and soldiers all around, it is too dangerous for you to go out, I will go to investigate the situation first, you wait here!" ”

Everyone didn't know that they had been used as bait to drag down the officers and soldiers, and they listened to the order silently, and even felt grateful to this young lady.

Bai Xiaohan took one last look at everyone, sneered in his heart, and flew out of the ruined temple.

100 meters away from the back slope, Zhang Zuofeng led the headquarters of the people to closely monitor the broken temple's every move, they were from the fierce battle all the way to follow, after the discovery of the enemy Zhang Zuofeng did not give the order to attack, but ambushed and waited for backup.

"Lord Baihu, someone from inside has come out, and the master of Hongwutang is following her."

The scout in charge of the lookout hurriedly rushed to Zhang Zuofeng's side and said.

"Has the Hongwu Hall enshrined ever left a mark?"

Zhang Zuofeng asked in a deep voice.

The scout said: "The masters of Hongwutang will leave marks along the way, we just need to follow the markers to follow!" ”

Zhang Zuofeng nodded, took out the waist knife in his hand, and coldly ordered: "That's good!" Brethren, let's take this ruined temple first, and then follow the signs to find someone! ”

In the western city, a steady stream of Jinyi guards were searching from house to house to leave, after that fierce battle, he and Bai Xiaohan fled separately, Li Kuang saw that he was injured, so he left Bai Xiaohan and chased after him.

"Bang Bang Bang"

There was a rough slamming sound, and Shangguan Buda mouthed the old butler Nunu, who hurriedly removed the latch and opened the door.

"Have you seen a single injured man?"

Li Kuang stood outside the door with a dark face and asked, and when he spoke, more than a dozen clothes guards had already rushed in and searched the room.

"No, no ......"

The old butler looked frightened and shook his head again and again.

Li Kuang also ignored him, silently watching his subordinates rummaging through the cabinets, and the old housekeeper and Shangguan Buda, like other Shunmin, stood aside tremblingly, not daring to speak.

The room was very small, and it didn't take long for the brocade guards who had entered the house to search came out one by one, shaking their heads at him, indicating that they had not found anything useful.

Li Kuang was disappointed for a while, glanced at the old butler and said, "If you see an injured man, report to the official immediately, the court will be rewarded!" ”

The old butler hurriedly nodded in agreement.

Li Kuang nodded, turned around and walked towards the next family.

"Wait a minute, sir!"

At this moment, Shangguan Buda suddenly stopped Li Kuang.

Li Kuang stopped and asked suspiciously, "What, have you seen this person?" ”

Shangguan Buda shook his head and said, "My lord, Xiaomin has never seen this person, but I found some abnormalities in Xicheng, I don't know if it will be useful to you." ”

"Oh?"

Li Kuang frowned and asked, "What anomaly have you found, let's hear about it." ”

Shangguan Buda said: "Xiaomin once heard a strange voice in a family. ”

"Weird sounds?"

"Yes, it seems to be a knock knock, knock knock, knock knock sound, very rhythmic!"

"What did you say?!"

Li Kuang was shocked, stepped to Shangguan Buda's side, grabbed his wrist, and shouted: "Say it again, what is the voice?" ”

Shangguan Buda seemed to be taken aback, and only said resignedly: "It's a knock knock, knock knock, knock knock sound, Xiao Minxue is not like it, but this sound is indeed very special......"

"Really? Which house is it, can you still find it? ”

Li Kuang asked excitedly.

Shangguan Buda nodded: "Yes, Xiaomin can find it." ”

"There's a clue, there's finally a clue!"

Li Kuang was overjoyed in his heart and muttered uncontrollably.

If what he expected was right, the sound of "knock knock, knock knock, knock knock" he had heard Xu Rui talk about during the Battle of Jingyang, saying that it was a kind of password.

Xu Rui also joked with him, saying that if he could become the commander of the Jinyi Guard, he would teach him this code and let him use it to transmit important information.

Because the rhythm of this voice was very peculiar, he still remembered it vividly, and this time when he heard Shangguan Buda mention it, he immediately realized that the voice must be Xu Rui himself transmitting information to the outside world.

Xu Rui, who had disappeared for three whole days, finally had news, how could this not make him feel excited?

"Come on, immediately notify the master of Hongwutang, and say that we have found someone!"

Li Kuang shouted loudly, and the brocade guards behind him immediately hugged their fists and left, but Li Kuang suddenly shook his head and said: "Slow, those offerings in Hongwutang are all guys with noses on their heads, I'm afraid you won't move."

In this way, send someone to inform the commander, and then stay here, and I will go to Hongwutang in person!" ”

"Order!"

As he spoke, Li Kuang arched his hand towards Shangguan Buda and the old butler, and with a slight touch of his feet, his body flew up like a fallen leaf and landed steadily on the war horse.

"Drive!"

Li Kuang was anxious and happy, and he didn't want to delay for a moment, so he raised the horsewhip and whipped it hard, and the war horse suddenly opened its four hooves and galloped away.

In the hut, he was quietly clinging to the dark side of the beam like a gecko, and the words just now fell into his ears word for word.

No one noticed that just above everyone's heads, a pair of fierce eyes were like evil ghosts in the night, tightly locking on Shangguan Buda.
