Speaking of which, this matter is a mystery nowadays, why are all plants dead, but the oxygen on the earth is still endless? Many places at high altitudes are surprised to find that there is no longer a lack of oxygen, but in this era when everyone is at risk, who would have the leisure to study this?

And now that the plants are dying in large areas, those large mountain ranges, forests, oases, wetlands, and all of them have become alien worlds, so this is why don't go from above the mountains.

Liu Shaoyun didn't speak, nodded, directly took out the miniature solar plane, and in the blink of an eye, he got on the plane and flew away.

Looking at Liu Shaoyun's figure leaving, Lan Yang and Sun Wei couldn't help but be a little puzzled, although Lan Yang asked them to rest and take a day off, but to be precise, there was only a twelve-hour holiday, what did Liu Shaoyun do when he returned to Yanjing in such a short time? But these, just by thinking, I can't understand it, so the two of them don't think about it anymore, set up a mechanical tent, get into the mechanical tent, and fall asleep.

……

Yanjing

"Why did you come back......" In a dark room, Liu Shaoyun was standing in the middle of the room, listening to the people in the corner.

"Half a day off." Liu Shaoyun explained: "So I returned to Yanjing. ”

"The North China Campaign is about to start, and this battle is related to the future situation of the entire China." The man in black said to himself.

"I know that the mission of our team is to recover Yuzhou City."

"Don't be stubborn, be wary of everyone." The man in black was still talking to himself, as if he hadn't heard what Liu Shaoyun said.

"In addition, reach the golden rank as soon as possible, so that you can have a voice in the upper echelons.

"Is there anything more than our squad's glory points?"

This time, the man in black seemed to hear Liu Shaoyun's words and said: "Most of those commanders of the Huaxia army have already reached the golden rank, and even the commander of the Huaxia Military Region is about to break through the golden rank and become a platinum commander. Among the soldiers, there are not many capable people, brave and good at fighting, killing countless enemies, and naturally they have also achieved the golden rank, and these people also have a certain right to speak.

"And Sun Wei in your team has achieved the golden rank, but you haven't found it." The man in black said hoarsely.

"Remember, improve your own strength, so that you can avenge your brother!"

Hearing this, Liu Shaoyun couldn't help but clench his fists and nodded heavily.

"If you can really reach that height of the Diamond Rank, I'll tell you the real murderer of your brother." The man in black laughed strangely, waved his palm, and fanned out a strong wind, fanning Liu Shaoyun out.

"It's not too early, you can go back!"

Liu Shaoyun gave a military salute, glanced at the time on his phone, and then flew back to the Haimen border in a solar-powered plane.

"Liu Shaoyun, Liu Shaoyun, your brother's death, I really don't want to affect you......" The man in black looked deep, stood by the bed in the attic, looked at the blue sky outside, and couldn't help muttering to himself.

……

Haimen Border ......

In the mechanical tent, Lan Yang and Sun Wei were falling asleep, and their sleeping posture was also very indecent, the two hugged each other, and their hands were also entwined together, and Sun Wei had a hara in his mouth, which was also like a small river, and flowed happily to Lan Yang's body.
