At noon, the sun was hot and the sand surface was filled with heat. The dry heat in the air entered the body through breathing, frying the lungs like flames, which made the chest suppressed and extremely uncomfortable. The air that came out was hot. Everyone had to drink water to extinguish the stuffy heat. They didn't carry much water and could not drink it hard. This feeling of frustration was crazy.

Fortunately, everyone rested for a morning and their physical strength and energy were recovering a lot. Luo Zheng ate some dry food, took his backpack, looked at Lan Xue with his weapon, and said in a deep voice: "You stay the commanding force, I will take Cao Xi to investigate the terrain, and be sure to find a location to excavate the tunnel."

"You can't do it alone, I'll come with you and have a look after both of you." Lan Xue said seriously.

Luo Zheng thought for a while, nodded and agreed, looked at everyone and shouted in a low voice: "Brothers, everyone are here to wait a moment, don't run around, Shan Diao, your people are dispersed, responsible for the alert, ghost hand, you are responsible for commanding before I came here, are there any problems?"

"Yes!" everyone shouted in a low voice.

"You stay." Seeing that Shi Qian also wanted to follow, Luo Zheng immediately reminded him: "You have to save your energy. We will act in the evening. Don't worry, I will be responsible for her safety."

"Well, be careful." Shi Qian said to Cao Xi with concern.

Cao Xi nodded, Luo Zheng glanced at Lan Xue, his eyes fell on Cao Xi, and said seriously: "There are deserts everywhere here, where are we going?"

"Going north, get closer to the base as much as possible and shorten the excavation distance. Any base must consider the water source. The desert is too far from the city, and road transportation is definitely not enough. Laying water pipes is easy to be poisoned and attacked. Groundwater is generally excavated. Therefore, there must be water sources under the base, and the water source comes from the underground river. What we need to do is to find the direction and location of the underground river and choose a safe point to do it." Cao Xi explained seriously.

When Luo Zheng heard that it made sense, he looked at the vast desert around him, wiped the beads of sweat from his face and said in a deep voice: "It doesn't look like an underground river here, but you are an expert in this field. Let's go if you listen to you."

The three of them walked towards the base under the scorching sun, walking as far as possible along the sand dunes, turning off all their electronic equipment to reduce the possibility of exposure, and did not speak, and used all their strength to rush on the road. Two hours later, the three of them walked about five kilometers, lurking behind a sand dunes, observing the surroundings vigilantly.

The surroundings were full of yellow sand. A lizard on the dune not far away was looking around vigilantly and ran away quickly. The wind blew the fine sand at the top of the dune and blew away in the distance. The surroundings were quiet and depressing. Only the scorching sun was hanging high in the sky. The stuffy air made people breathing hard. Luo Zheng couldn't bear the sultry heat anymore. He looked at Cao Xi with a sweaty head, with his eyes full of inquisitiveness.

Cao Xi understood the surrounding terrain and suddenly pointed in one direction, with a shocked expression on his face. Luo Zheng was startled and turned his head to go. He found that a team suddenly emerged from the sand dune in front. There were about ten people, lined up in a column and looked around, observing the patrol team.

"Looking at the surrounding terrain, the patrol may pass by us." Lan Xue reminded in a low voice.

Luo Zheng also discovered this problem, his face darkened, and he quickly observed the surrounding terrain. It was too late to run, so he could only hide. Thinking of this, Luo Zheng quickly looked at Cao Xi and said, "Buried yourself with sand, only your face is exposed outside. Although the sand temperature is very high, the clothes on his body have heat insulation effects. Don't worry about scalding, hurry up."

"Okay." Cao Xi reacted and agreed, quickly plucked the fine sand around him, dug a long sand pit and lay down, sat in and piled the surrounding sand on his body, smoothed it as much as possible, then lay down, and continued to pile the fine sand on his body with both hands. At this time, Cao Xi found that Lan Xue and Luo Zheng had hidden it, and the sand in his body was level with the surroundings, only showing his face outside, and there was no suspicion. Unless he was around, it would be absolutely difficult to find.

"Hurry up." Lan Xue reminded.

"Uh?" Cao Xi reacted and quickly continued to pile up the surrounding sand on his body, filling his whole body, and then smoothed it so that the sand on his body was at a height from the surroundings. Finally, he squeezed into the sand with both hands and wore special tactical gloves on his hands, which had a strong insulation effect. Otherwise, he would have to be burned by the high temperature of the sand.

The head rests on the bulletproof helmet, on the ground at a high place, wrapped in a scarf on the neck, and no sand flows into the neck. There is no way to go to the sand on the high side of the face. If you buried it all, you must be burned. This is the only flaw. Whether you can avoid it depends on luck.

Luo Zheng felt the hot temperature under the sand, as if he was lying in an oven. Although the clothes on his body were insulated, he couldn't bear it anymore. He had to endure it desperately and looked at Cao Xi worriedly, and found that Cao Xi's face was also red, and beads of sweat as big as beans rolled down, and he was gritting his teeth and persevering.

"It is not simple to withstand the high temperature." Luo Zheng said intimately, knowing Cao Xi a little more, and looking at Lan Xue worriedly, and found that Lan Xue's face was also hot and red. She was gritting her teeth and insisting, her brows were frowning, and she felt very distressed. She heard the enemy's laughter and laughter. She quickly abandoned her distractions and calmed her mind and waited.

Soon, the laughter and footsteps became clearer and clearer. Everyone gritted their teeth and persevered, not daring to move for a moment. Luo Zheng could feel the water in his body was rapidly losing, and his heart was so depressed that it was madly depressing. This feeling could make people run away. But for the sake of the task and for everyone's safety, Luo Zheng tried his best to endure it and looked at Cao Xi worriedly. Luo Zheng was very relieved about Lan Xue's patience, but Cao Xi was not a soldier and had no special training, so he might not be able to hold on.

At this time, Cao Xi's eyes closed slightly, his lips were clenched, his face turned red like fire, and his breathing seemed to slow down. Luo Zheng was shocked. This was a sign of endurance and would go wild at any time. He couldn't help but hold the gun in his hand tightly and prepare for battle. Once exposed, he could only fight to the death.

The thing that made Luo Zheng worry didn't happen. Cao Xi actually endured the hot test, and the patrol team gradually moved away a hundred meters away from everyone, and walked down a hill and disappeared.

"Huh!" Luo Zheng quickly sat up, letting the fine sand on his body fall, and looked at Cao Xi worriedly. While getting up, he shouted anxiously: "Everyone comes out, how are you?"

Lan Xue quickly got up. Seeing Cao Xi moving hard, she couldn't get up anymore, so she quickly climbed up to help. Luo Zheng rushed up, and the two supported Cao Xi from the sand pit, and looked at Cao Xi with concern. Luo Zheng even took out his kettle and handed it on, asking anxiously: "How is it?" r1148
