After a pause, Song Feifei suddenly struggled to push Xia Wanyi out.

And Xia Wanyi was prepared this time, and when Song Feifei felt that something was wrong, he reacted that something was going to happen!

So even the action changed from supporting to hugging in an instant, and when this action was converted, as soon as Song Feifei's words came out and her hand was pushed, Xia Wanyi also took her out by the way.

And here, Xuanyuan Yu also noticed that something was wrong, jumped up, stepped on a stone and pulled out the saber on his body, and then while approaching Xia Wanyi, he threw the purple star sword to Xia Wanyi, who had already landed and stood on the ground.

As soon as Xuanyuan Yu arrived at Xia Wanyi's side, a fire immediately rose from the place where they were standing just now, and some dead leaves on the ground burned together, and some of the unwilted plants and trees next to them were instantly turned into black charcoal!

Nima, this is a catastrophe!

Xia Wanyi looked at the raging fire not far away in horror.

Looking at this scene, Xuanyuan Yu was dumbfounded.

"Hurry up and cover your mouth and nose!" Xia Wanyi smelled something wrong, so she shouted, "Retreat!" ”

Song Feifei and Xuanyuan Yu immediately followed Xia Wanyi to cover their mouths and noses, and then retreated.

After retreating to a safer distance, Song Feifei in Xia Wanyi's arms breathed a sigh of relief as if she had lost a thousand pounds of burden, but her shoulder was aggravated by the hard push just now.

She clutched her shoulders and coughed violently, almost falling into Xia Wanyi's arms. The latest chapter of нéi Уāпgê has been updated

Holding Song Feifei, Xia Wan asked anxiously, "How are you?" ”

Song Feifei said weakly: "I'm sorry, I forgot that the mouth of the Big Dipper is also oriented. ”

Xia Wanyi hugged her tightly and didn't blame her: "It's okay, as long as the person is fine." ”

Xuanyuan Yu patted some of the ashes floating on his body and understood: "In this way, the dipper of the Big Dipper points to the west, then its mouth should face north, and we should also go west from the south, not from the north to the west like now." ”

"Well, we need to retreat to the position of the Celestial Hub, and then go west from the south." Song Feifei said weakly.

"But that's going to take a climb!" Xuanyuan Yu looked at Song Feifei, who was not lightly injured.

"But if we don't go that way, we can't get out." Song Feifei said.

"Wait a minute, I'll go and see why the fire suddenly broke out just now." Xia Wanyi said, "Xuanyuan takes care of Miss Feifei. ”

Xuanyuan dissuaded: "Childe, let's go." ”

"Hurry up!" Xia Wanyi became serious.

Helpless, Xuanyuan Yu didn't dare to disobey the order, so he stepped forward to take Song Feifei from Xia Wanyi's arms: "Son, be careful." ”

"Hmm!" After taking the Purple Star Sword, Xia Wanyi walked towards the place where the fire suddenly broke out just now.

took out a black face towel from his arms, covered his mouth, and Xia Wanyi walked to his destination.

Stir the place that had become a fire pit a few times with his sword, and then carefully check the surroundings.

In the end, it was concluded that this is a chemical reaction of white phosphorus!

White phosphorus, if you have studied chemistry, will know that it is a flammable substance, and its ignition point is 40 degrees Celsius, but the heat generated by friction or slow oxidation may cause the local temperature to reach 40 degrees Celsius and burn, so it cannot be said that it will not spontaneously ignite at temperatures below 40 degrees Celsius.

After checking and confirming that it was white phosphorus spontaneous combustion, Xia Wanyi walked back.

It's just that he doesn't know why there is white phosphorus here, and even if there is, it can't be so coincidental that it spontaneously combusts as soon as they arrive, right?!

Could it be because Song Feifei stepped on the mechanism? Or is it the ancient sorcery?!

MLGB, Evil Gate!

"How's Childe looking?" Seeing that Xia Wanyi came back safely, Xuanyuan asked.

"Hmm." Xia Wanyi nodded, and then asked, "I don't know if you have heard of white phosphorus?" ”

"White phosphorus?" Xuanyuan said, "Isn't that something that produces ghost fire?" ”

I actually knew that Xia Wanyi was a little strange, this phosphorus element was discovered by the Germans in the seventeenth century, but I knew that the relationship between white phosphorus and the appearance of ghost fire was in the Southern Song Dynasty.

Lu You recorded in "Notes on Lao Xue'an, Volume 4": When Yu was more than ten years old, he saw many ghost fires in the suburbs, and the branches of wheat seedlings and rice ears often burst into flames, and the color was green, and Russia was gone. Gai is not in the army for a long time, and the so-called human blood is phosphorus, and it is not in vain. Now it will never be seen again, and those who see it will think it is strange.

Old Man Lu's explanation is a little materialistic.

In ancient times, the "ghost fire" that appeared on summer nights was the small particles of white phosphorus that burned freely in the air, and because the white phosphorus burned with a blue-green flame, there was a misunderstanding that "ghosts appeared".

"Do you believe there is a ghost fire in this world?" Xia Wanyi asked.

At this time, Song Feifei listened quietly to their conversation.

Xuanyuan Yu shook his head and said, "How can there be ghosts in this world, I think, most of them are caused by man-made. ”

"Hahahaha, yes!" Xia Wanyi looked at Xuanyuan appreciatively from the perspective of modern people and said, "This so-called 'ghost fire' often occurs in cemeteries or suburbs. In these places, because some animal or human bones contain phosphorus, phosphorus reacts with water or phosphorus to produce a gas called oxygen phosphide, which can spontaneously combust, and the weight is light, when the wind blows, it will move, and when you walk, it will drive it to move behind, and when you look back, it is very scary. That's why it's superstitiously called 'ghost fire'. ”

"Then why did Childe tell us to cover our mouths and noses just now?" This is Song Feifei is also curious, but her tone is very weak.

Glancing at Song Feifei, Xia Wanyi said: "This white phosphorus is highly toxic, and if you inhale it in large amounts, it can lead to illness and even death!" ”

I see! Xia Wanyi's words made Xuanyuan Yu, an iron-clad man, couldn't help but speak.

Xia Wanyi knew that the amount of white phosphorus that caused human poisoning was 15 milligrams, and the lethal dose was 50 milligrams. Even long-term inhalation of phosphorus vapor can lead to tracheitis, pneumonia and severe bone damage!

Therefore, Xia Wanyi picked what they could understand and told them.

"How could Childe know so much?" Xuanyuan asked admiringly, although he knew that Xia Wanyi was smart since he was a child, he didn't expect to be able to talk about the relationship between him.

Xia Wanyi is actually a liberal arts student, but he used to be in mathematics, physics and chemistry, but because of his love for political history, he chose liberal arts, but he did not choose a major related to history and politics in college, nor did he choose a speechless major, but chose a media major.

"I know that the method of making phosphorus is extracted from the bones of humans or animals, but the fire just now is not small, how many bones do you need? And these are the bones of a man, or are they the bones of an animal? Xuanyuan asked suddenly.

This question stopped Xia Wanyi......
