"How did it get out?" Zuo Dengfeng frowned and pondered, and the big head kept talking to himself.

"Wouldn't it be better for it to run out, and we won't be hindered when we go to find indium arsenide." Wan Xiaotang said.

"The black water on the fifth level of the pyramid is corrosive, it shouldn't have escaped, I'm worried now that someone released it, if that's the case, the time machine might have been taken away." The big head shook his head and said, his worries were exactly the same as Zuo Dengfeng.

"Except for your master, uncle, you and your friend, who else knows the location of the pyramid?" Zuo Dengfeng frowned and spoke.

"We came with eight people and hired a group of locals. However, the pyramids are located deep in the desert and are still hidden underground, making it difficult to find them once you leave the area. The big head replied.

"How likely do you think someone else is to find that underground pyramid?" Zuo Dengfeng asked patiently.

"The chances of others finding the pyramid in the desert are almost zero, and it's hard to find a reference unless you know how to look at qi." The big head shook his head and said.

"What is the reference?" Zuo Dengfeng asked again, the current bad situation is just speculation, and it is not yet time to give up.

"It." The big head held out his short fingers and pointed to the west side of the town.

"What? Its breath is your reference? Zuo Dengfeng was directly stunned when he heard this, and regardless of whether the crashed time machine was still in the pyramid, it was a problem to even find the pyramid at present.

"yes, it was trapped underground, I didn't expect it to escape." The big head nodded in amazement.

Zuo Dengfeng raised his hands to cover his cheeks when he heard this, and at the same time sighed long, things were far more difficult than he imagined, the cobra ran out, the reference was gone, and the west side was an endless desert, if there were camels, they could also carry supplies to look for them, but where to find camels that didn't bite right now.

"Zuo Zhenren, what now?" Wan Xiaotang also discovered the seriousness of the problem.

"I'm tired of the day, let's rest for a while." Zuo Dengfeng put down the wooden box, and the roof of the gas station was wide and flat, high above the ground, which could be used as a resting place.

"I remember walking west for five days, and the location of the pyramid was a Gobi in the desert, and there were a few thorny plants around it, and I should be able to find it." Big Head isn't sure.

"You're still looking for plants?" Zuo Dengfeng raised his eyebrows and glanced at Da Da when he heard this, now that there are no plants in the world, he is still thinking about using plants as clues.

"I'll think again." The big head was completely panicked, he came as a guide this time, but at present, he was obviously derelict as a guide.

"Don't think about it, there's only one way now." Zuo Dengfeng took out a bottle of liquor from the bag and unscrewed the lid.

"What's the solution?" Wan Xiaotang and Datou asked in unison.

"The old horse knows the way." Zuo Dengfeng lifted the bottle and took a sip of wine.

"yes, I didn't think of that." The big head suddenly became ecstatic when he heard this, he understood what Zuo Dengfeng meant, Zuo Dengfeng wanted the cobra to lead the way, since it could run out, it would definitely be able to run back.

"Don't be too happy, for now we need to make sure that cobra is conscious." Zuo Dengfeng let out a long breath, the nuclear weapons of the Japanese devils have polluted the whole world with viruses and bacteria, if this cobra is also infected, then it will not have its own sanity, and it will not be able to recognize the way.

"Sober, absolutely sober, poisonous insects that contain venom in their bodies and whose venom can be lethal have some resistance to the virus." The big head excitedly stretched out his hand and pointed west, "Besides, its breath shows that it is normal." ”

"What kind of cultivation is it?" Zuo Dengfeng was relieved when he heard this.

"The time machine that crashed earlier also has radiation, it became like that after being exposed to radiation, its ability cannot be measured by our standards, but its cultivation is not higher than the light purple aura, because it can't be volleyed." The big head replied.

"How big is it?" Zuo Dengfeng nodded and asked again.

"I don't know, it was transformed into a human form at the time, let's go over and take a look." The big head looked up to the west side.

"You don't even have a basic plan, so you're going to go and scare the snake?" Zuo Dengfeng raised his eyebrows and glanced at the big head.

The big head laughed twice when he heard this, and stopped talking, Wan Xiaotang's task is to fly a plane, and he is not good at dealing with this kind of thing, so he can only shut up.

"First of all, we must make sure that we can't lose the trail of this cobra, which is the premise." Zuo Dengfeng said after groaning, he had suffered the loss of the Yin Fire Snake before, and at the critical moment, the Yin Fire Snake got into the sand and escaped, and no matter whether the cobra could get into the sand or not, even if they ran around, the three of them might lose it, and once they lost it, the only chance was lost.

"Qi Observation can see it." The big head interfaces immediately.

"If it gets down here, you won't be able to see it." Zuo Dengfeng stretched out his hand and pointed to the iron roof of the gas station, although he didn't know how to observe qi, he knew that there was a flaw in qi observation, that is, he couldn't see through iron metals.

"Now that tracking and positioning has become popular, we can place a positioning device on it." Wan Xiaotang said.

"Explain clearly." Zuo Dengfeng asked.

"As early as ten years ago, a small electronic product appeared, this electronic product does not need to use satellite positioning, as long as this device is placed on a person's body, you can know where the person is, usually within 300 miles effective." Wan Xiaotang explained.

Zuo Dengfeng didn't react for a short time when he heard this, and Wan Xiaotang spoke again when he saw this, "The main function of this kind of electronic product is to let the husband and wife grasp the movements of one of them and prevent the other party from buttoning the green hat and wearing red shoes." ”

"Is there such a thing in Egypt?" Zuo Dengfeng was overjoyed when he heard this, if he could know where the cobra went, he could better conceive the plan.

"Definitely, in the big cities." Wan Xiaotang spoke again, she was more familiar with these things than Datou, Datou was a Taoist priest, and he spent more time in the mountains than outside, unlike her who flew around and was well-informed.

"Let's go, let's go find this kind of thing first." Zuo Dengfeng closed the wine bottle and carried the wooden box.

Wan Xiaotang and Datou also packed up their things, three people and a cat quietly left here and went back, eighty miles to the northeast is a very big city, when I arrived here, the sky was already slightly bright, the city was full of dead people, Zuo Dengfeng took the two of them to volley through the streets of the city, and soon found the building that sold electronic products, and also successfully found the tracking and positioning device, which is composed of two parts, a palm-sized utensil with a screen, which can be observed and positioned. There is also a small object placed on the person being followed, mostly in the shape of jewelry and buttons.

For the sake of safety, Zuo Dengfeng and Datou did an experiment, Datou went out with a button, and the direction and distance of Datou immediately appeared on the screen.

This kind of positioning device Zuo Dengfeng took two, once it was used, it must be foolproof.

Found the positioning device, Zuo Dengfeng was not in a hurry to go back, but broke into the residential area one by one to look for the child corpse, at this time the child corpse was not easy to find, Lang spent more than an hour and finally found the body of a boy about two years old, Zuo Dengfeng casually froze the child corpse that wanted to bite, and handed it back to the big head.

Back at the gas station outside town, Big Head observes the cobra's breath and makes sure it's still there.

Zuo Dengfeng used a small glass bottle to install and seal the two button-shaped positioning devices, pinched open the mouth of the child corpse, and sent the glass bottle to its stomach with aura, the glass is resistant to strong acids, if the cobra devoured the child corpse, the positioning device can stay in its abdomen for a long time.

"Will that cobra eat it?" Wan Xiaotang looked at the corpse of the child lying beside him.

"Yes." Zuo Dengfeng nodded and said, there is not a single dead corpse around, this situation is naturally caused by the cobra, judging by the behavior of the Yin fire snake piling up corpses and bones on the periphery of the dead woods, the snake should also have the concept of territory, and it will attack if it breaks into its territory, and it will kill it even if it is full.

"When will you be fed?" Wan Xiaotang asked again.

"In the afternoon, when the weather is hot, snakes are more active and have a strong desire to eat." Zuo Dengfeng said that the reason why it wanted to find the corpse of the child was to facilitate the devouring of the poisonous snake, and since it did not know the size of the poisonous snake, the smaller the food, the better.

"In the desert, our body will be affected, and the root cause is nothing more than that our feet will sink into the sand when we borrow strength, we have to find a way to increase the landing area of our feet and increase our movement speed in the desert." Zuo Dengfeng looked at the big head.

"It has to be wear-resistant, it has to be able to bend, it hasn't been too soft." The big head analyzed the posture of the landing, while quickly thinking about the appropriate materials, and after a moment, he reached out and pointed to a large discarded tire next to the gas station, "Use rubber." ”

Zuo Dengfeng felt that it was feasible, so he and the big head cut a tire for testing, and quickly cut two pedals after determining the suitability, Zuo Dengfeng's pedals were two inches thick, one foot long, and half a foot wide. The pedals of the big head are slightly smaller than his, and the rubber used in the tires itself has a certain curve, just enough to ensure that the front end does not insert into the sand. The wire is used for bundling, and the sand is relatively light on the wear of the wire, which can be supported for a long time, and can be re-tied even if the wire is broken.

Then Zuo Dengfeng ordered the big head to cut two pedals, one large and one small, to spare, to ensure that there are spare pedals to replace in the case of damage to one, this pedal can greatly increase the speed of the two in the desert, at least sixty percent of the body on the ground.

It was already noon after the two of them were busy, and the temperature on the roof was very high at this time, so the three of them came to the gas station to rest for a while, and after eating and drinking, Datou and Wan Xiaotang took a nap.

Zuo Dengfeng closed his eyes and pondered, woke up the two of them at about two o'clock in the afternoon, and quietly approached the town with the child corpse......
