Pei Yuansong put the gas mask on his head, and a look of surprise immediately appeared on his face.

He also felt a little difficult to breathe, and his chest was uncomfortable.

However, after putting on the gas mask, my breathing became much easier, and the tightness in my chest was gone.

Pei Yuansong took off his gas mask in disbelief, and the feeling of poor breathing and chest tightness hit him again.

As soon as he put on the gas mask again, the feeling disappeared immediately.

Pei Yuansong was overjoyed and nodded at Shen Lingyue.

With this gas mask, he was sure that the people of them would be able to climb Als with ease, and even enter the crater to reach the bottom of the volcano with much ease.

This is a great help for them to obtain the Ignition of the Earth.

As we all know, it is still at the foot of the volcano, and it is already difficult to breathe and chest tightness.

It would be even more difficult to go any further up, let alone at the bottom of the volcano.

Pei Yuansong looked at Shen Lingyue with a magical gaze.

The girl in front of you is always able to surprise people again and again.

Every time you feel impossible, she is always able to make the impossible possible.

Such a girl is simply incredible.

The effect of Pei Yuansong's experiment was completely unexpected by Shen Lingyue.

So she wasn't much surprised, but continued to refine the gas mask.

There were nine of them, so they needed nine of these gas masks.

And she didn't let Pei Yuansong and the others be idle, but asked them to pick those bright red herbaceous plants that grew at the foot of the volcano.

Although Pei Yuansong and the others didn't know why Shen Lingyue wanted them to pick those plants, after seeing the miraculous effect of Shen Lingyue's gas mask, they all guessed that Shen Lingyue must have an important use.

So everyone obediently began to pick those plants.

Because this is the only plant that grows here, and there are many of them all over the mountains.

So they picked a lot of these plants very easily.

According to Shen Lingyue's request that the more the better, the plants they picked were piled up into a hill in front of Shen Lingyue.

When they were almost finished, Shen Lingyue also finished refining the remaining seven gas masks.

She divided the gas masks one by one, and began to dispose of the plants.

Everyone didn't understand what these plants were used for, and how they would be of any help to their assessment.

Shen Lingyue took out the medicine pod and lit the fire.

While throwing these plants into the medicine pod, he explained to everyone.

"It's normal that you don't know these plants, because they only grow on volcanoes. ”

"This plant is called Breathing Grass!"

"Any living thing needs air to survive, but what it really needs is oxygen in the air. ”

"You should have noticed that the air here is very thin because of the high temperature of the volcano, and the reason for this is because the oxygen in the air is consumed a lot by the heat. ”

"But when you look at these breathing grasses, they are growing so luxuriantly. ”

Everyone looked at it according to their words, and sure enough, the breathing grass all over the mountains danced in the wind like wheat waves, full of vitality.

Shen Lingyue continued: "But breathing grass also needs oxygen to grow so lushly. ”

This shows that even in the hot and scorching heat of this volcano, the breathing grass does not lack oxygen, on the contrary, it also contains nutrients that can produce oxygen. ”

"And what I'm refining with the Breathing Grass right now is the Oxygen Creation Pill. ”

"Have you noticed that the gas mask has a circular groove near the nose?"

If Shen Lingyue didn't say it, everyone really didn't pay attention to it.

Now that Shen Lingyue reminded him, everyone noticed that there was indeed a circular groove there.

The size is the size of a normal elixir.

When Zhou Jie saw it, he suddenly had an idea, "Sister Shen, this shouldn't be the place where the Oxygen Creation Pill you are refining is placed, right?"

Although she was asking Shen Lingyue, she actually had the answer in her heart.

Shen Lingyue praised: "What you said is right, it is the oxygen pill that is placed." ”

Shen Lingyue was talking as he refined the Oxygen Pill, and soon he refined a furnace.

Shen Lingyue lifted the lid of the medicine pod, and there were nine oxygen-making pills lying quietly inside.

Zhou Jie was dumbfounded.

She licked her dry lips and looked directly at the nine top-grade oxygen pills in the medicine pod.

Her heart was shaken.

Ever since she began to learn to refine medicine, she had never seen anyone refine nine top-grade pills at once.

What surprised her even more was that others were all engrossed in refining medicine, for fear of being affected in the slightest.

But on the other hand, Shen Lingyue is very casual, she can also be distracted and talk when refining medicine, and the speed, quality, and quantity of refining medicine are also breathtaking.

Zhou Jie admired and envied her.

She didn't know that Shen Lingyue's current cultivation could already be one god inside and one god outside.

There is nothing wrong with being distracted.

Shen Lingyue took out the pill and put it in the jade bottle, and found that Zhou Jie was still crazy on the side!

patted her on the shoulder and said, "Do you want to learn?"

Zhou Jie came to her senses under Shen Lingyue's pat.

However, she didn't hear what Shen Lingyue said clearly.

When Zhou Qingyang saw it, he pulled his sister and said, "Thank you Miss Shen, Miss Shen is willing to teach you how to refine medicine!"

When Zhou Jie heard this, she was pleasantly surprised, and hurriedly stepped forward to thank Shen Lingyue.

She has been studying with the alchemist in her family until now, and she has never studied with a teacher.

So although the talent is good, there is no famous teacher to guide him.

Now that Shen Lingyue is willing to teach her, and she is her idol again, she is naturally overjoyed.

Shen Lingyue said with a smile: "You have a good talent for refining medicine, as long as someone gives you a little guidance, coupled with your own efforts, you should have good results." ”

Shen Lingyue did not stop while talking to Zhou Jie, but continued to refine the medicine until all the breathing herbs in front of him were refined into oxygen pills, and then put away the medicine tripod.

She divided each of the refined oxygen pills into a bottle.

Only then did he say: "When the time comes, if you can't breathe well, then put an oxygen pill into that groove." ”

Everyone nodded yes.

Shen Lingyue looked up at the sky, it was actually night at this time, but it was still a fiery red place, and she couldn't see any difference from the day.

Shen Lingyue thought for a while and said, "I think let's go up the mountain as soon as possible, this is a dangerous place after all, although it is now in the recreation period, who can guarantee that there will be no sudden changes?"

Everyone also agreed with Shen Lingyue's idea.

So the group put on gas masks and headed for the crater.

They had only been walking for a while, and they met many students who were hurrying back.

Their faces were generally pale and bloodless, and their clothes were dirty and torn, and they were in a terrible mess.
