Maybe someone wants the secrets here to be buried forever. Xiao Yifan estimates that there is a space of its own, and the rock wall is at least a few meters thick, if it is excavated, it is undoubtedly a huge project that cannot be completed in a short time.

wanted to rely on the huge waterfall to cover everything, but it aroused Xiao Yifan's curiosity, what secrets were hidden, and even the buries didn't want it to see the light of day.

After nearly a quarter of an hour of investigation, Xiao Yifan was convinced that he had no way to take this rock formation, so he continued to descend.

There was nothing else to find along the way, and the distance of twenty or thirty meters was not far, and soon, Xiao Yifan came to the deep pool at the bottom of the waterfall. Walking here, he was a little helpless, now, the flow of water almost covered his whole body, and it was difficult to control the air to create a vacuum coat to keep him from dripping, after all, this place was almost full of water, and he could hardly touch the air.

He gritted his teeth and simply jumped directly into the water, and it was useless to control the air flow in order to keep his clothes dry.

With a drop of more than 100 meters, the waterfall falls into a deep pool and then hits down several meters of white foam before the clear water flows.

Xiao Yifan held his breath and slowly groped down, the pool was very deep, Xiao Yifan was a few meters underwater, but he still couldn't see the bottom. The cliffs stretch underwater, and the rock walls are covered with algae-like plants, dancing with their teeth and claws in the undulating water.

Xiao Yifan subconsciously dodged, if he was entangled in these aquatic plants, it would be enough for him to drink a pot. Now, his whole body is soaked in water, and he can't "drip without sticking", the only thing he can do is to control the flow of water to form a coat similar to the formation of the control air just now, so that the aquatic plants can't get close.

Suddenly, Xiao Yifan's expression froze, and the rock wall more than ten meters underwater was a little smooth, even if it was covered with aquatic plants, it could not hide that there were traces of polishing here.

Continuing down less than half a meter, Xiao Yifan lifted the water weeds, and what caught his eye was the ancient rock paintings, the characters on the murals were somewhat similar to the ancient Egyptian murals, but there were faint traces of non-Egyptian civilization, and many places were blurred, which made him unable to judge the year and source.

Due to the years of soaking in the water, the rock murals have been very blurry, and it is midnight, and it is more than ten meters deep here, and there is no trace of starlight at all, Xiao Yifan wants to see the murals clearly, and he also feels a headache.

Although he is a god and his physical fitness is far beyond ordinary people, under the water pressure of more than ten meters, holding his breath for more than ten minutes, Xiao Yifan still feels dizzy. In desperation, he could only float to the surface for ventilation, but unfortunately, the mural was not very clear at all.

Xiao Yifan smiled bitterly, it seems that next time it is better to be fully armed, this time he came out privately without preparing diving props at all, but he relied on his strong physical fitness to support it, and it was too restrictive.

Diving into the water again, Xiao Yifan began to copy the mural in his brain, controlling the memory neurons to forcibly burn the scene in front of him, and there was no mistake in any subtle place. Of course, this requires a huge amount of energy and at the same time exacerbates the consumption of oxygen, and this time, he only lasted less than five minutes before resurfacing again.

This way back and forth four times, the huge mural was copied into Xiao Yifan's brain, and he dived into the water for the sixth time, and dived towards the bottom of the mural. Xiao Yifan found that the traces of the excavation under the mural were very clear, as if there was no river here, and the mural was carved on the bare cliff, but it was buried by the river later.

In other words, these paintings may be older than the age of the Zambezi River! Xiao Yifan feels a little incredible, the oldest rock carving civilization relics found by mankind so far are only a few thousand years, and the formation of the Zambezi River is at least the last ice age, its history has to be calculated in 10,000 years, if it is really that old, this mural has long been blistered by the river without the slightest trace.

And if such a huge project is completed underwater, Xiao Yifan does not think that human beings in any period in history can complete it alone.

The polished rock wall continued to extend down for less than two meters, and then returned to the appearance of strange rocks, and when he arrived here, Xiao Yifan believed that there was no more useful information below, so he prepared to return to the water.

But at this moment, Xiao Yifan found that there was a piece of aquatic grass here that was not undulating in the water as at the beginning, but inhaling and spitting, as if on the edge of some abyss.

He swam in that direction and found a dark hole in front of him, and the aquatic plants were sucked in at one time and spit out again, indicating that it was not a dead end, but connected to another place of living water.

This is the Zambezi River, I haven't heard of other rivers near Victoria Falls, and the cave is supposed to lead to an underground river, or rather...... Xiao Yifan suddenly thought of the position of about thirty meters on the water, that broken rock formation, could it lead there?!

Xiao Yifan has been in the water for more than five minutes, and the ascent is definitely faster than the dive, excluding some uncertain factors, it will take at least a minute to slowly rise to the surface, that is, he can stay underwater for more than three minutes at most.

However, this reason was not enough to make him retreat, and now that he had already arrived, he decided to go into the cave and have a look. Moreover, if you don't succeed this time, you can still surface, and the next dive will be more purposeful, so you don't have to take so long to get here.

Entering the cave, it is even darker and the water is much colder than the outside. The entrance to the cave is small enough for only one person to pass through, and the floating aquatic plants obscure the view.

After entering the cave, the space became open, Xiao Yifan breathed a sigh of relief, if the passage had always been as big as the entrance of the cave, it would be a problem to turn around at that time, which would undoubtedly increase the difficulty of the survey. Of course, this difficulty was not enough for him to pose a threat, and it was much more dangerous than this when he went deep into the bottom of the sea in the Strait of Gibraltar with Cen Shu.

After sneaking inward for more than a minute, the abyss was still bottomless, but he was a little excited at this time, because he could vaguely see a glimmer of light in the distance, and he was particularly sensitive to light with super night vision in the night. However, he had to withdraw, and if he continued to swim forward and the oxygen in his body was depleted, then he would probably have to make some big moves here to escape, and he might be in the headlines tomorrow.

Xiao Yifan retreated to the surface, took a deep breath, and after his breathing was stable, he dived directly into the cave, the time was twice as long as last time, but Xiao Yifan didn't dare to stop, after all, the last time he swam for more than a minute, the glimmer was still vaguely unknown how far away.

Swimming towards the glimmer of light with all his might, he found that the glimmer was getting brighter and brighter, but the time was also passing by minute by second. Due to the extreme speed, the oxygen in Xiao Yifan's body is consumed extremely quickly, but this allows him to maximize the cost performance of the remaining oxygen in a short period of time.

More than a minute passed, and Xiao Yifan's speed did not decrease, but at this time, because of the intense oxygen consumption, he could no longer hold his breath in the water for more than ten minutes, and the limit time was sharply shortened.

Staying underwater for more than seven minutes, nearly two minutes of which are running at high speed, although he can maintain the speed of a normal person in a fifty-meter sprint in the water, but two minutes is also the limit, there is not much oxygen left in his body, but fortunately, the front is getting brighter and brighter. The moment the oxygen ran out, it was only fifty meters away from the light.

Xiao Yifan evoked the god chromosomes, letting the current of water push him forward, and finally, within seconds of running out of oxygen, he suddenly rushed out of the water, and before he could see what it was, he closed his eyes, greedily sucked air into his chest, and then spit out quickly.

After gasping for a while, Xiao Yifan opened his eyes, but the scene in front of him made him stunned. It seems to be a piece of artificially excavated heaven and earth, completely excavated in the mountain, the space is about thousands of square meters large, more than 40 meters high, a river passes through the middle of the earth, and the priceless night pearls outside are dotted everywhere on the mountain wall, and the night pearls are all embedded in the stone miles, making the whole space resplendent in gold.

Just when Xiao Yifan was shocked, he suddenly felt a strange fluctuation.

"Who is it?" Xiao Yifan snorted coldly, the sun, moon and stars in his eyes were reflected, and at this moment, even the night pearl on the mountain wall lost its color.

Seeing that no one responded, Xiao Yifan clasped his hands together, as if he was pulling something, and the elements of the entire space were agitated, and the forty-seventh chromosome in his body released dazzling gamma rays at this moment, and the gene fragments resonated strongly, making the whole person under the light.

"Okay, okay, I'll just come out!" seemed to see Xiao Yifan's next move, the guy who was hiding nearby was unexpectedly soft, but the voice made Xiao Yifan startled, and suddenly looked up at the person in front of him, the corners of his mouth kept twitching.

"You...... You're really fooling around!" Xiao Yifan glared at Olivia, his face was even more blue than the green pearl of the night, and he only held back one sentence for a long time.

This mysterious figure hidden next to Xiao Yifan is naturally Olivia. Xiao Yifan was a little surprised at first, but he was relieved in an instant, he was very clear about the taboos that Olivia was good at, no wonder he was very well-behaved when he got on the plane at that time, even Xiao Yifan was a little puzzled, it turned out that she had a plan.

Olivia and Xiao Yifan stared at each other, and soon, when Xiao Yifan calmed down, he scolded Olivia with his head and face, but Olivia didn't care, anyway, they were already here, and Xiao Yifan couldn't drive her away, so she was scolded.

"Yes, yes, you're right......" Listening to Xiao Yifan's reprimand, Olivia's consciousness of admitting mistakes is quite high, but only she knows whether she has the consciousness of correcting it.

"You have an old Chinese saying," Olivia thought as she suddenly had a flash of inspiration, "Oh, by the way, the raw rice is already cooked anyway, so you can just watch it." ”

Listening to Olivia's incomparably "single" answer, Xiao Yifan's eyes were black, almost spewing out a mouthful of old blood, and said in his heart Who taught you Chinese over the years, call him to me I promise not to kill him, "raw rice cooked rice" is you using this?

But the matter has come to this, Xiao Yifan can only hate this "scourge" with iron and steel. As Xiao Yifan expected, Olivia used two taboos - "Wuji" and "Thor" to track him.

The former is an ancient taboo, allowing users to use gas molecules to control the light to project an image that is exactly the same as themselves, of course, this is projected out of a virtual body, which can only be deceived by the eyes, it is estimated that after getting on the plane, Olivia will use the excuse to rest and find a closed room to lock himself in, and when the plane arrives in London, the guards may find something......

As for "Thor", it is a taboo that has only been developed in recent years. It was invented by a guy who likes to watch Japanese anime, perhaps because of the inspiration seen in anime, so even the name hasn't changed much.

This taboo is the same as the effect in the anime, the user leaves a spell on the thing he has touched, and then he can instantly go to the place where the spell has been left at any time, on the surface, this taboo seems to be related to space like in the anime, but in fact it is just a microscopic molecular dispersion, and the so-called technique is just a signal circuit.

The place where Olivia left the circuit technique was naturally on Xiao Yifan's clothes. However, this "taboo" is a method to control the ion residue, and ions are extremely unstable, so its storage time is very limited, and once the elements and ions in the procedure have a chemical reaction, the procedure disappears.
