The qi of yin and yang is one of the purest energies in heaven and earth, and it is of course extremely harmful for Zhang Tingting to rush into her body without knowing it just now. But if someone knows how to transform and absorb safely, then the benefits to her for those who have obtained the Yin and Yang Qi are undoubtedly huge.

Zhang Tingting felt a little light at this time, because she absorbed some of the yin and yang qi that Lu Xiao had helped her transform, slightly improved Zhang Tingting's physique, and cleaned up some of the impurities in her body that had accumulated over the years.

After listening to Lu Xiao's explanation, Zhang Tingting suddenly realized, but when she saw Ah Zi and Xiaobai, who had been asleep, she still asked with some concern: "Brother Lu!" Ah Zi, the two of them will be fine, right? ”

"No, they, like us, have just absorbed the purest yin and yang qi. However, the evolutionary path of these supernatural beasts is very different from that of us humans, which is why this kind of sleep-like digestion energy appears. Lu Xiao briefly explained to Zhang Tingting, and then asked: "Tingting! The underground river we fell down contains cold yin energy, so your body will be full of yin energy, but where did the yang energy in your body come from, did you come into contact with some hot objects in the river? ”

"Brother Lu, when you fell, it was this cold underground river?" Hearing Lu Xiao ask about the yang energy in her body, Zhang Tingting asked in surprise.

"What's going on? Didn't you fall into this underground river when you fell? Hearing Zhang Tingting's rhetorical question, Lu Xiao suddenly felt as if he had caught something.

Zhang Tingting nodded affirmatively, and then explained to Lu Xiao: "When I fell, it was a very hot underground river, just like a hot spring with a high temperature, and bubbles were constantly bubbling from the bottom of the river. The current of the river was so fast that I was swept into a hot and cold whirlpool without even a chance to swim ashore, and then I was thrown out of the whirlpool and entered the icy underground river. I was in a coma when I was thrown out. ”

"Blazing? Extreme cold? And the whirlpools of convergence? After listening to Zhang Tingting's explanation, Lu Xiao muttered these words to himself, but his eyes became more and more solemn.

If I didn't guess wrong, not only were the two banks and the treasure place they were about to go to artificially constructed, but even the two underground rivers were not naturally formed, they were also artificially constructed.

"Yin and Yang Moat!" This is the word that instantly flashed in Lu Xiao's mind after analyzing the results.

"Brother Lu! Is there anything wrong with what I'm talking about? Zhang Tingting observed that Lu Xiao's face was a little solemn, and asked worriedly.

Looking at Zhang Tingting's concerned eyes, Lu Xiao nodded a little solemnly, and slowly said to Zhang Tingting: "I'm thinking about the Yin and Yang Moat. ”

"Yin and Yang Moat?" Zhang Tingting obviously heard this name for the first time, and looked at Lu Xiao with curiosity repeating in her mouth.

The so-called yin and yang moat is to protect a certain city or a certain place, after a large number of manpower and material resources to dig out, the introduction of recyclable volcanoes to give birth to hot lava meltwater and extremely cold ice water, with the principle of yin and yang poles through a precise feng shui layout, arranged a kind of Liangyi formation.

If you look down from the air, it is like a moat that forms a circle on the periphery of a city or a certain place, and it is generally a place where there is a whirlpool in the direction of the north and south poles, and the rest of the place is half ice water and half hot water is constantly flowing. If you have a thermal imaging instrument, you can see that half of the circle is blue and the other half is fiery red.

After this formation was successfully arranged, although it was not comparable to the Nine Heavens Star Formation, this formation that followed the principle of Yin and Yang was the most headache for all those who wanted to enter the building it protected.

Since ancient times, yin has not separated from yang, and yang has not separated from yin. There are only two ways to enter the city protected by this formation.

The first method is to use centrifugal force to turn yourself into two vortices of yin and yang rotation. But just like Zhang Tingting was thrown out, the closer you get to the center of the whirlpool, the greater the centrifugal force, and at this time, it is almost impossible for you to enter the calm place underground in the center of the whirlpool.

The second method is the combination of yin and yang, that is, a man and a woman enter from the yin and yang magnetic field formed by them along the correct trajectory.

This method is much more difficult than the first one. First of all, someone needs to have a very high level of feng shui attainments, otherwise maybe the next step will be torn apart by the trigger point of the yin and yang two ritual formations constructed by the yin and yang moat. Secondly, it is necessary to be accompanied by the opposite sex in order to be able to integrate into the yin and yang.

But even if this method is used to reach the final obstacle, if the people inside deliberately block all the passages that can enter it, then the only way to wait for the two people is to return the way they came. Because there are still rules to follow when you go from the outside to the inside, but from the inside to the outside, all the mechanism formations that have been re-changed are all nowhere to be found, which can be described as extremely dangerous.

After listening to Lu Xiao's detailed explanation, Zhang Tingting suddenly realized, and after pondering for a while, Zhang Tingting raised her head, her eyes were still full of hope and stubbornness.

"Brother Lu! Are you trying to tell me that maybe the treasure of our ancestors was put in it? ”

After listening to Zhang Tingting's inquiry, Lu Xiao nodded lightly.

"Yes, through the series of situations we have experienced and in the Nine Heavens Star Formation, we have even used such a big stroke to build this Yin and Yang Moat, I have reason to believe that that the Supreme Treasure should be stored in it."

The two of them had just said this, when there was another rustling sound in the place where the big turtle was.

Hearing this voice, Lu Xiao Yile also wanted to ask the origin of the mysterious bead of the big turtle! So Lu Xiao asked Zhang Tingting to wait here now, and then he stepped on the big rock just now.

However, Lu Xiao, who had just stepped on the boulder, did not have the slightest surprise and hope, but roared with extreme indignation.

"Your sister!"

The reason why Lu Xiao was so sad and indignant was that at this time, on the beach where the big turtle had just buried the turtle eggs, it was not the big turtle that appeared, but the mutated extinct gold-eating ant that almost didn't kill Lu Xiao's old friend in the Longjing Mountain Range.

If there is such a mutated extinct gold-eating ant in the Longjing Mountains, it is still understandable from the perspective of geographical latitude and deep underground. However, this is the edge of the subarctic zone in the north, and this is still above the horizon, so it stands to reason that there are no such mutated extinction gold-eating ants here!

"It's not scientific!" Lu Xiao sighed in his heart, there were hundreds of millions of mutant locusts above, and there were mutated extinction gold-eating ants that covered the sky and the sun, Lu Xiao really wanted to know how such a huge population of them survived.

Moreover, why did this species, which originally only existed in a specific region, appear in two formations that had a certain connection with the god organization, and what was the inevitable connection between them, Lu Xiao's heart was full of questions.

But when he saw what the thousands of densely packed extinct gold-eating ants were doing, Lu Xiao's heart instantly swelled with boundless anger and sadness.

Because they are eating the eggs of the big turtles buried there.

The eggs of the turtles that still exist in the form of egg whites and yolks, the baby turtles that have not yet hatched, were wiped out by these abominable extinction gold-eating ants in this world before they could see this beautiful world.

Lu Xiao could imagine how heartbroken and sad it was when the big turtle came back and saw his children being eaten by these extinct gold-eating ants.

At this time, in front of Lu Xiao's eyes, there was only one turtle egg left that was still well preserved.

Faced with the extinct gold-eating ants that covered the sky and the sun, the turtle eggs that were about to be eaten and had nothing to do with him, and the situation that he was likely to die here if he made a move, Lu Xiao jumped over the boulder without the slightest hesitation and faced the extinct gold-eating ants that covered the sky and the sun.

Lu Xiao, who had just landed, instantly attracted the attention of these extinct gold-eating ants, Lu Xiao didn't say a word, and lifted the sand in the sky with a powerful kick, and after the breakthrough, Lu Xiao's strength soared, and those sand hit the extinction gold-eating ants in the front row made that kind of "poof" sound.

Taking advantage of the fact that the extinction gold-eating ants in the front row were beaten back by their own sand attacks, Lu Xiao took a few steps to the only turtle egg that still had hope of survival, picked it up and put it in his arms, and then "Bang!" He stomped on the sand fiercely, lifting a sand curtain again, and once again slightly blocking the extinction gold-eating ants behind him.

Then Lu Xiao's whole person flew backwards in an instant like a cannonball, jumped over the boulder with lightning speed, and ran wildly in the direction of Zhang Tingting.

When the sand fell, the extinction gold-eating ants that were attacked by Lu Xiao and the delicious food was snatched away by Lu Xiao were all stumbling? The roaring voice covered the sky and the sun to pursue Lu Xiao with all his might.

Just now I saw Lu Xiao still walking towards the big stone with a smile, how could it be that in less than a few seconds, Lu Xiao's whole person ran towards her quickly and solemnly, what happened?

"Hug Xiaobai and Ah Zi!" Lu Xiao, who had not yet run over, shouted anxiously to Zhang Tingting loudly.

Although I don't know why Lu Xiao let herself do this, Zhang Tingting was stunned for a moment, and then immediately followed Lu Xiao's instructions and picked up Xiaobai and Ah Zi who were still sleeping one by one.

At this time, Lu Xiao also ran to Zhang Tingting's approach, hugged her tightly again, and ran towards the cold river with all his might......
