In the car, Brother Ting said apologetically to Li Xi and the three of them: "I'm really sorry, you guys didn't come by chance, just in time for a sandstorm here, otherwise the sky in Lanzhou is still very blue and clear, and the air is much better than now!"

Li Xi listened and asked, "Why do you often have sandstorms here?"

"Hey, don't mention it," Brother Li said dejectedly, "In recent years, sandstorms have become more and more frequent, I remember that when I was a child, I only encountered them once in several years, and now, almost several times a year!"

"Mainly in recent years, there have been too many people grazing and cutting down trees, and the environment has been damaged too much!" Brother Li said with a wry smile.

"By the way, distinguished guest," Brother Li asked, "do you want to go to dinner first or go straight back to the hotel?"

Well, Li Xi thought for a moment and asked, "Is the Mogao Grottoes far away from us?

"Well, we're not going there tonight. Mogao Grottoes are on the edge of Dunhuang, far away from Lanzhou, there are more than 1,000 kilometers of road, tonight we will stay in Lanzhou for one night, tomorrow morning to drive over, it is estimated that tomorrow night will be able to reach Dunhuang. Brother Li replied.

Li Xi was taken aback when he heard this, and said involuntarily: "What, it's so far! Xiao Tang, why don't we just take a plane to Dunhuang, how do you arrange the itinerary?"

Thinking of this, Li Xi couldn't help but glared at Tang Haoran fiercely.

I saw Tang Haoran touch his head a little embarrassed, and said: "Boss, don't I just want to take the opportunity to come out and have more fun! Besides, anyway, all the fares and hotel meals are reimbursed by the teacher, so you should take it as a public expense to travel and travel!"

"That's it, Brother Xi!" Su Xiaoxiao also echoed, "We haven't traveled for a long time, so we should come out to relax this time!"

"You ...... Li Xi was speechless for a while, and he didn't know what to say, so he could only reluctantly agree and said, "Okay, the matter has come to this, then it can only be like this!"

"Oh! great!" Hearing Li Xi's answer, Su Xiaoxiao and Tang Haoran cheered.

Then, Li Xi turned his head and said, "Brother Li, then let's go eat first, what are the specialties and delicious in Lanzhou?"

"Oh, speaking of our Lanzhou, there are so many delicious things!" Brother Li replied proudly, "The most famous is of course ramen, which is different from what you eat in other places." In addition, there are hand-fingered mutton, mille-feuille beef patties, stuffed skins, etc., which are all a must for us here!"

"Wow, there are so many delicious foods!Brother Li, then what are we waiting for, let's go quickly!" Tang Haoran almost drooled when he heard that there were so many delicacies, and he urged Brother Li impatiently.

"Yes, yes, I want to eat everything!" Su Xiaoxiao also looked salivating, and said again and again.

Dizzy, these two people are really foodies! Li Xi looked at them and thought helplessly.

Finally, under the leadership of Brother Li, the three of them came to a special food street in Lanzhou and had a good taste of local food.

Subsequently, Brother Li sent Li Xi and the three of them, who had almost eaten enough, to the hotel, and after agreeing on the time to meet the next morning, he drove away from Li Xi and them.

The three of them opened two rooms, one for Li Xi and Tang Haoran, and one for Su Xiaoxiao.

At night, Li Xi stood in front of the window of the hotel room, looking at the scenery outside the window. I saw that their hotel is located in the downtown area, surrounded by high-rise buildings, and the lights are bright. Although it was late at night, the street was still brightly lit and crowded, a bustling scene.

Li Xi couldn't help but feel that the development of human society is changing with each passing day, and people's lives are constantly improving. However, there are various contradictions between man and nature, such as the increasingly serious environmental problems today. Perhaps the increasing frequency of sandstorms is a warning from nature to humans.

Just when Li Xi was thinking wildly, I saw Tang Haoran walking over with a full burp while touching his round belly, and said, "Boss, hiccup, what are you looking at?" Do you want to go out for a walk, do you want your little brother to accompany you?"

Li Xi asked strangely, "What, don't you have to do evening classes?"

"What are you doing, it's finally come out, so don't you take the opportunity to have enough!" Tang Haoran said nonchalantly.

As he was talking, suddenly Tang Haoran's mobile phone rang, he picked it up and looked at it, his face suddenly changed, and he said: "It's over, it's the master's phone, he wants to video call me, you have to help me panic!"

The moment he answered the phone, the expression of the hippie smile on his chubby face immediately became serious.

I saw him respectfully say to Tianchen Zhenren on the other end of the phone: "Master, good evening!"

"Hehehe! Hello apprentice!" Tianchen Zhenren's hearty laughter came from the other end of the phone, "I want to ask you, has your accession to the WTO been smooth so far?

Tang Haoran replied solemnly: "Master Hui, everything is going smoothly in the current task, and there is nothing abnormal. In the homework, the disciples also kept in mind what the master said, and did not dare to slack off for a moment. The disciple has just finished the evening class and is discussing his cultivation experience with Senior Brother Li!"

"Oh! that's good!" Tianchen Zhenren replied with relief, and then he said to Li Xi: "Li Daoyou, this time I have to trouble you to take care of Haoran more!"

Li Xi listened and replied: "If you are also an immortal cultivator, you don't have to be too polite! Besides, Brother Haoran is talented and intelligent, and his cultivation is also very hard, and I like him very much!"

"Hehe, since that's the case, then I won't bother you, goodbye!" Tianchen Zhenren said.

Seeing Tianchen Zhenren hang up the phone, Tang Haoran let out a long breath.

"Boss, that's interesting, you didn't expose me!" Tang Haoran gave Li Xi a thumbs up.

"Hehe, you've invited me to travel and eat, I still have to help with this little favor!" Li Xi said with a slight smile.

Tang Haoran held Li Xi's hand tightly and said gratefully: "Thank you, boss, rest assured, I have covered all the expenses of this journey!"

After this toss, the two of them didn't have the heart to go out shopping again, so they rested early.

…………

Early the next morning, Ali arrived on time in an off-road vehicle, and the four of them moved towards the next stop, Dunhuang.

Not long after Li Xi and the others left, another off-road vehicle followed them.

Along the way, Li Xi and the others passed through several natural scenery and historical monuments such as Colorful Danxia and Jiayuguan, and the magic of nature and the magnificent momentum of the vicissitudes of ancient ruins made Li Xi and the three of them amazed and amazed.

In the evening, the car finally arrived in Dunhuang City.

Dunhuang City is not big, the population is only more than 100,000, but the surrounding cultural relics are very rich, the more famous are Mogao Grottoes, Yulin Grottoes, West Thousand Buddha Caves and other historical landscapes. In recent years, with the vigorous development of tourism, more and more tourists have come to Dunhuang for tourism, and at the same time, it has also driven the economic development of the whole city.

Li Xi and the others stayed in the best hotel in the city that night, and Tang Haoran was not bad for money anyway.

After a good night's rest, the next morning, Li Xi and the others set off towards their final destination, Mogao Grottoes.

The Mogao Grottoes are not far from Dunhuang, only more than 20 kilometers. Soon, Li Xi and the others arrived at the Mogao Grottoes.

Brother Li, who is reliable, has already helped them book tickets online. It's good, it's not the peak tourist season, and there aren't many people visiting. So, soon they were in this world-famous monument.

Entering the cave, Brother Li took on the role of their tour guide again.

I saw him introduce as he walked: "This Mogao Grottoes, also known as the Thousand Buddha Caves, is one of the three major grotto art treasure houses in China. There are 492 caves, 45,000 square meters of murals, and 2,415 painted statues. It was also listed as a UNESCO World Heritage Site in 1987. "Brother Li's introduction is very professional.

As the tour deepened, one cave after another appeared in front of Li Xi and them. Almost every cave is home to beautiful murals and lifelike Buddhist statues.

"Wow, that's beautiful!" Su Xiaoxiao looked at the murals in the cave and couldn't help but say.

Li Xi and Tang Haoran were also impressed by the exquisite painting craftsmanship and ingenious carving skills of the ancients.
