Lu Sheng remembers that the teacher in junior high school physics class said that flame is actually a kind of infrared, and the temperature determines the color of the flame. Normal is 3,000 degrees of red and orange, 4,000 degrees to yellow and white, 5,000 to 6,000 degrees of cyan and blue, and 7,000 degrees of purple.

Lu Sheng was very glad that although the physics teacher died early, Lu Sheng still remembered this knowledge. It doesn't matter what kind of divine fire is white, the important thing is that it is a high-temperature flame.

What kind of light divine fire is just a trick to deceive people, it must be mastered by a certain way of burning to obtain a high-temperature flame. In this era, there were no such disciplines as physical chemistry, but mathematics developed extremely rapidly.

Nature's treasure trove has yet to be truly explored. Although martial arts is a panacea in this world, there is at least one thing that cannot be replaced, that is, material transformation and energy transformation.

Therefore, Lu Sheng believes that it should be very difficult for this world to obtain the conditions for high-temperature flames.

"Shen Ling, since the conditions for forging the Star Striped Divine Weapon are so harsh, then we can use this condition as a filter. First of all, the star rune, I remember that in the file, one of the three masters of the Ministry of Engineering who died unexpectedly was a rune master, right?

And the superb forging skills, looking at Li Xiucheng, I know that a Xiucai has been forced to become a skilled blacksmith in just three years?

But only this flame is the most difficult to get, it can be obtained without a heart, and it can be obtained without sincerity!"

"Naturally, according to the Ministry of Works, the light divine fire is skillfully obtained, and the star-patterned iron cannot be melted if it is not the bright divine fire. But the light and fire are only in the secret place of the Ministry of Industry...... Don't...... Did the Starstriped Divine Soldier still flow out of the announcement?"

"Impossible, the capital is thousands of miles away from Tongnan Mansion, if Li Xiucheng was transported back from the capital, the body would have decomposed quickly. We can see the intact Li Xiucheng, which shows that he is not far from Tongnan Mansion.

The flame is white because it is twice as hot as a normal red flame, and that's it. The reason why it is difficult to melt star-patterned iron is that the temperature is not high enough.

Shen Ling, check the information, has there been any natural gas found in Tongnan Prefecture?"

"What is natural gas?"

"It's a gas that comes out of the ground, a gas that burns like biogas...... Combustion is also a rapid oxidation reaction, and in addition to combustible gases, oxygen is also an essential key. ”

Lu Sheng muttered to himself, and Shen Ling could only be stunned for a while.

It's a hot June day.

Even in the dark basement, the heat is still suffocating. And even in such a sweltering environment, there are dense braziers lit in the empty underground space.

The brazier consumes oxygen, making the air in the space even more turbid.

But even so, there were a dozen mysterious people wearing masks standing quietly underground. Each one was dressed in pitch black, shrouding all the skin on his body in pitch black.

No one made a sound, and the whole scene was audible with pins dropping.

Even his breathing was as long as a drizzle, as if he was afraid that he would destroy the dead silence in front of him because of his breathing.

Everyone looked at the quaint throne above their heads, and on the throne, a burly man sat on it. The man also wore a flame-like mask, and his invisible aura rippled like ripples.

"How long has Lu Sheng been in Jiangbei Province?" I don't know how long it took for the man on the throne to speak.

"It's been almost two months since I returned to my master......"

"Two months...... In just two months, the layout of this seat for 20 years has been messed up...... Where are they tracking down now?"

"One last step!" replied with a shrill voice from the man wrapped in a thick quilt beside him.

His voice was so ugly, but no one showed the slightest hint of impatience.

Everyone was standing, but he was able to lie down. This shows that this guy who seems to be weak and may be dying at any time. The status is extraordinary.

"In the first month, Lu Sheng got the Gu Mother first and configured the Gu poison antidote. After solving the case of the disappearance of the child fifteen years ago, I realized that we were secretly supporting the Japanese invaders. At the same time, the Smoke Willow Villa was leveled, and the nails that had been buried by the Japanese for decades were pulled out.

In the second month, Lu Sheng once again found out the minerals of the Starstriped Divine Soldier, cutting off our back road to produce the Starstriped Divine Soldier, and now he has found out that our secret industries are all mainly produced by prisoners.

At Lu Sheng's speed, it was a matter of time before we found our factory and uprooted us. I said a long time ago that I can't let Lu Sheng live, he is a trouble, and I should have killed him as soon as he entered Jiangbei Province. ”

"He is a dignified sword saint, a sword saint who flies from the sky to the west, who can kill him? Is it you, or this seat? Once we make a move, we will take the initiative to expose our own ......."

"What about now? Because of hesitation, we have retreated to the corner, and we may be pulled out by Lu Sheng at any time, and when the time comes, we will all have to die. The only way to do this is to kill him desperately, and that Shen Ling. ”

"As soon as Shen Ling dies, the sky will fall apart. ”

"If he doesn't die, we won't be able to recover! Are you still so indecisive? You should understand that if you are as indecisive as before, it is not only our group of people who have been buried in the loess themselves, but the ...... in the palace."

Dead silence, dead silence again.

"Xie Jianhao!"

"Master!"

"You're responsible, kill him!"

"Yes!"

It was almost dusk, the phantom was swaying, and the sky above the entire Tongnan Mansion was shrouded in a thick layer of murderous power.

The streets of Tongnan City are not the same as those of Suzhou Prefecture, and by dusk, there are not many pedestrians on the streets.

The earth emitted a compelling wave of heat, as if distorted green smoke rose from the barbecue stand.

A young man in a strong suit, looking at the dark clouds in the western sky, paused silently.

Pursed his lips tightly, and said, "There is heavy rain tonight, which is suitable for killing." ”

In the dungeon of the Punishment Division, wailing was everywhere. Under the leadership of Duan Fei, Feng Jian and other Xuan Tianwei were busy collecting confessions from officials and contractors. No detail is missed.

Shen Ling stepped up to get in touch with the headquarters and exchange information. Now is the critical time to race against the people behind the scenes. If they are slow down for a day, the people behind the scenes will have one more day to sweep away the beginning and the end.

Lu Sheng reorganized the intelligence collected and the progress of the case in the past two months. Although they have never faced each other head-to-head with their behind-the-scenes opponents for two months, the competition between the two sides has never stopped.

Lu Sheng and the masterminds behind the scenes, such as the blindfolded swordsmen, kept testing each other, kept making moves, and kept dismantling them.

Although it seems that the mastermind behind the scenes does not seem to be clever, he will kill people and break the wrist of a strong man. But this is precisely where the mastermind behind the scenes comes in.

The truly powerful move is to win without a move, and the truly clever layout is to seek the yang!

The layout of the Lingzhu County Lord back then was clever, constantly disturbing Lu Sheng's sight, and even did not hesitate to go into battle in person. But the more clever the layout, the easier it is to leave flaws.

It is good to link one ring at a time, but as long as there is an accident in one link, then it is a thousand miles and all the plates are lost. And the mastermind behind the scenes encountered this time, he told Lu Sheng his layout, but Lu Sheng was helpless.

Because it was fast enough, the fast Lu Sheng was out of time, and finally found some clues and planned to pursue him, but found that after finding the source of the clues, the other party had already cut off the clues.

If the Lord of Lingzhu County used the trick of Random Flower Charming Eyes, then Lu Sheng's opponent this time was a word hidden!

This is the opponent Lu Sheng has seen in his two lives combined, and he is also the most forbearant opponent.

The candle flame swayed violently, like the fluttering wings of a butterfly.

Lu Sheng gently put away his mind and slowly raised his head to look at the dark roof.

Under the light, Lu Sheng's face was a little haggard. A large amount of information rolled up a huge wave in my mind.

"Although the Criminal Division is very busy today, many people have endless things to do. However, you can still successfully sneak in here, your skills are not ordinary......"

"Who!" Gai Ying at the door suddenly shouted, and his figure jumped onto the roof in a flash.

On the roof, a young man stood quietly...... It's not quite like youth. Because this person just looks younger, but his real age must be older than Gai Ying.

Gai Ying's eyes burst with this essence, and his face was unprecedentedly dignified.

He has been guarding Lu Sheng's door, and has always fulfilled the duty of a personal guard. But, even so, he didn't know when the other party appeared on the roof?

Gai Ying's eyes were very cold, and he slowly drew his sword and pointed at the mysterious person opposite. But Gai Ying didn't make a rash move, he knew that the other party was very strong, and it was stronger than he had ever seen.

"I can't imagine that among the imperial eagle dogs, there is a master like you...... It's no wonder, after all, it's the Sword Saint Lu Sheng's subordinates...... A strong general has no weak soldiers under him, and it should be considered. I'm not here for you today!"

"I don't know where Your Excellency's confidence came from?" A voice sounded, and Lu Sheng's figure appeared beside Gai Ying out of nowhere.

The other party's eyes shrank suddenly, and the same feeling as Gai Ying magically appeared in the mysterious person's heart.

When did he come?

Even if his eyes didn't blink, Lu Sheng appeared by Gai Ying's side so magically.

Lu Sheng looked at the mysterious person in front of him curiously, at first he thought it was a killer sent by the mastermind behind the scenes. But looking at it now, it's clearly not.

Such a person, single-handedly entering the Criminal Division, no matter how you look at it, it looks like he is looking for death. If you were behind it, you would never do such a stupid thing.

After looking at the person in front of him for a long time, Lu Sheng suddenly showed a playful smile on his face, "You are the one who ranks fourth on the list of young masters...... Ghost Assassin?"

"Is the Sword Saint sarcastic? The Sword Saint is ranked seventeenth on the list of young masters, and now that Liu Qingyun is dead, everyone knows that the Sword Saint is a well-deserved top two. Whether it's the first or the second, I'm afraid we won't know until you fight with Bu Feiyan. ”

I don't think the answer will ever be there. But I'm curious, what are you doing with me?

"I don't care about these false names, since I am called the Ghost Assassin, I am naturally here to kill people, someone wants your life, I am here. ”

"I've heard that the Ghost Assassin is the number one killer in the world, but his men have never killed a good person in vain. Isn't it?"

"I kill for money, but I never kill for money. Whoever I kill will have a place to die. ”
