The three of them packed up and followed the cobra westward, and since the cobra did not move fast, the three of them adopted the method of walking, always maintaining a distance of twenty miles.

To the west is the Gobi Desert, an area where there are few dead bodies and wild beasts, and the ground is relatively solid and easy to walk.

The cobra stops and goes, sometimes turns around and swims for a few miles, with a locator in hand, the three of them can grasp its movements at the first time and hide and dodge in time.

"Zuo Zhenren, let your cat follow it, can it move faster?" The big head said that in the first half of the night, the cobra only traveled a short distance by walking and stopping.

Zuo Dengfeng frowned and groaned for a moment when he heard this, his previous idea was to wait until the cobra stopped and then let Thirteen go over to chase after him, now it seems that letting the cobra know that Thirteen is following behind can increase its psychological pressure to a greater extent, forcing it to speed up its progress, the most important thing is that the cobra knows that Thirteen is following, so he will not try to find other nests, and in desperation, he can only return to the underground pyramid where he was before.

Thinking of this, Zuo Dengfeng adopted the opinion of the big head and ordered Thirteen to follow five miles behind the cobra, so that the cobra could detect its existence, and the three of them were fifteen miles apart, hanging far behind.

After the cobra found Thirteen, it really increased its moving speed, and the movement route became straight to the west, which showed that it had a clear destination, which made Zuo Dengfeng secretly happy, and the two put on the pedal and quietly followed behind with Wan Xiaotang.

Camels with smudged hair can be seen in the desert from time to time, and they will avoid cobras when they see them, but they are not afraid of Thirteen, and they will run to attack after discovering Thirteen, and Thirteen's claws cannot open their throats, but can only scratch their eyes and make them unable to see.

Zuo Dengfeng was slightly puzzled when he saw this, in terms of strength, Thirteen is not inferior to that cobra, in terms of toxicity, Thirteen likes to eat poisonous insects, and the toxicity in the body is violent. Why are these beasts afraid of cobras, but not thirteen.

After groaning, Zuo Dengfeng felt that there was only one reasonable explanation, that is, the cobra had been exposed to radiation before, and the radiation had changed its physique, which could restrain those infected humans and animals infected by the virus.

"What is the use of indium arsenide in addition to lasers?" Zuo Dengfeng asked the big head next to him.

"I don't know, I didn't know there was this metal before." The big head shook his head and replied.

Zuo Dengfeng nodded when he heard this, and did not ask again.

The cobra has been moving westward, and when it reaches the day, it moves faster, day and night, and Zuo Dengfeng sees this, and he is more and more convinced that it is going back to the underground pyramid, but another worry comes to his mind again, that is, the wreckage of the time machine is still not in the pyramid.

The ancients used to describe Yanagishita Hui's concentration, Zuo Dengfeng has always thought that Yanagishita Hui's undisturbed posture is because the woman sitting in his arms is an ugly monster, so he can do it without disorder. Wan Xiaotang is very delicate and plump, holding her for a long time makes Zuo Dengfeng feel very awkward, his shoulders can feel soft, his arms can feel plump, and there is the sound of breathing in his ears, these are all torment for Zuo Dengfeng, he desperately wants to put down Wan Xiaotang, but he is still carrying a wooden box behind his back, so he can only hold her forward.

Hug for a minute, hug for an hour can stand it, hug for several days in a row, during this period, how much effort is needed to restrain the thoughts in his heart only Zuo Dengfeng himself knows, fortunately, although he can't control the thoughts, he can control his desires, and every time he restrains himself with Xuanyin True Qi before reacting, the cold and hot on his body make Wan Xiaotang ask him from time to time if he is sick.

There are not many animals in the desert, all the small animals are extinct, and occasionally some hairless camels and sand wolves can be seen, and the impact of viruses and bacteria on living things is gradually extinct from the bottom to the top, and it will not be long before the large animals will starve to death due to lack of food.

Three days later, in the middle of the night, the cobra suddenly disappeared, but the locator showed it to be there.

"That's it." The big head looked around and then stretched out his finger to the west, "The underground pyramid is there, and it got in." ”

The three of them are still more than ten miles away from the place where the cobra disappeared, Zuo Dengfeng did not answer when he heard this, and quickly swept to the place where the cobra disappeared with Wan Xiaotang, and found that there was a small hole in the ground, and most of the hole had been blocked by sand.

Finding his destination, Zuo Dengfeng breathed a sigh of relief, let go of Wan Xiaotang, and took out the clear water to feed the thirteen.

Then the big head who came also breathed a sigh of relief, put down the giant axe and sat aside to breathe, it was a five-day journey, the cobra swam over in three days, and in these three days, except for Wan Xiaotang who closed his eyes, neither of them rested.

"Sleep for a while, don't rush in." Zuo Dengfeng took out the water and handed it to Datou and Wan Xiaotang, the two had previously underestimated the consumption of clean water in the desert, and the food and drinking water prepared were obviously insufficient, and only Zuo Dengfeng's wooden box still had clear water at this time.

After thanking the two of them, they took the bottle, and Zuo Dengfeng handed them all iced drinking water, quenching their thirst in the scorching desert.

Although Wan Xiaotang was carried forward by Zuo Dengfeng most of the time, the long-term ups and downs still made her extremely uncomfortable, her face was pale, and her spirit was listless, and she was only slightly relieved after drinking ice water.

"It's a blessing or a curse, it's a disaster that can't be avoided, if the time machine is moved, let's find another way." Zuo Dengfeng comforted the nervous head.

"It should be fine, there are no traces of excavations around here." Big Head's words are more or less self-consoling.

Zuo Dengfeng smiled and nodded when he heard this, in fact, he was more nervous than the big head at the moment, if the thing he was looking for was not here, he could only find another clue, the trip to Egypt should be the easiest, no need to face mechanisms and obstacles, and no need to face the treacherous terrain, if there are branches in this simplest task, it will inevitably take a lot of time, and then he will have to go to the North Pole, I am afraid that the time will not be enough.

"No, I'll have to go in and have a look." The big head looked up and drank the ice water dry, and walked to the gap with the giant axe.

Zuo Dengfeng raised his eyebrows and glanced at him, but did not say anything to stop him, first, the big head had gone down before and was familiar with the situation inside. Second, the cobra was not a threat to him.

Most of the entrance to the pyramid was buried in the sand, but the big head was small and easily drilled through the gap.

"Meow~" Thirteen looked down at the gap, and looked up at the left peak from time to time, it was curious and eager to go down to find out.

Zuo Dengfeng nodded at Thirteen with a slight groan, and Thirteen got Zuo Dengfeng's permission and immediately jumped down.

"Let's go down too." Wan Xiaotang said.

"The environment down there isn't good for you." Zuo Dengfeng shook his head and said, the Egyptian pyramids are similar to the tombs of Chinese kings, but this pyramid is not built on the ground, and there is no coffin of the Egyptian king.

"Didn't the big head say that the mechanisms inside were all broken by them, and the air below has been circulated for such a long time." Women are also curious.

"That cobra is still down there." Zuo Dengfeng shook his head again.

"Isn't there thirteen?" Wan Xiaotang looked down, but unfortunately it was dark all around, and he couldn't see his fingers below.

Zuo Dengfeng raised his eyebrows and glanced at Wan Xiaotang when he heard this, and did not answer her words again, he stayed outside not to simply protect Wan Xiaotang, but also to protect Datou, he must ensure that Datou has reinforcements to rescue him when he encounters danger, and he must also ensure that the retreat is unimpeded.

Wan Xiaotang saw that Zuo Dengfeng insisted on not saying anything, and sat aside to drink water quietly.

"It's still !!" After half a pillar of incense, there was an excited shout from the big head below.

Zuo Dengfeng was relieved when he heard this, he didn't like this kind of uncertainty the most, the danger here had been broken before, and outsiders could enter, although there was no danger in this situation, there were great variables, far less reliable than the protection of the dangerous organ.

After determining that the wreckage of the time machine was still in the underground pyramid, Zuo Dengfeng was relieved, but he did not go down, since the purple-robed Taoist left the clues to the big head, it was more appropriate for the big head to find it, unless the big head said for help, he would not take the initiative to take action.

After the big head shouted, Wan Xiaotang did not approach the gap, but quickly ran towards the sand pile on the north side, Zuo Dengfeng thought that she wanted to relieve herself, and did not ask.

"Zuo Zhenren, the black water below has turned green and is no longer corrosive, you can come down and take a look." The big head shouted again from below.

"Wait a minute." Zuo Dengfeng replied.

Then there was no sound coming from below, and after a while, Thirteen jumped up from the gap, the corners of his mouth and claws were stained with a large amount of snake blood, Zuo Dengfeng frowned slightly when he saw this, Thirteen and the big head must have started to kill, in fact, although the cobra looked ugly, it was the hero who led the way, and Zuo Dengfeng didn't want to kill it.

Thinking of the cobra, Zuo Dengfeng couldn't help but think of the black water that the big head said had turned into a non-corrosive green, no one had been to this place before, this change was undoubtedly caused by nuclear radiation, although the current clues could not deduce any results, but he always felt that something in the time machine could neutralize or suppress the bacteria in the corpse.

Due to the lack of clues at present, Zuo Dengfeng had no further inferences, retracted his thoughts and looked around, and found that Wan Xiaotang had not come back yet.

"Not done yet?" Zuo Dengfeng raised his voice, the big head was still waiting below for the two of them to go down to help, he would definitely not leave Wan Xiaotang alone above.

After Zuo Dengfeng shouted, Wan Xiaotang did not respond.

Seeing this, Zuo Dengfeng suddenly remembered a detail, Wan Xiaotang had a small flashlight that he carried with him, and he would use it to illuminate his hands at night, but this time she didn't turn on the flashlight when she walked towards the sand dunes, and she used to walk to relieve her hands, but this time she used to run.

Thinking of this, Zuo Dengfeng quickly dodged to the back of the sand dunes on the north side, and found that Wan Xiaotang was not here, and there was no sign of defecation around, and a row of footprints led straight to the north.

Zuo Dengfeng eagerly searched in the air, and at a glance, the soul of the dead was rising, and Wan Xiaotang was moving rapidly northward in the desert, and he was about to exceed the range of ten miles......
