(PS: This is what I wrote before going to bed and set the update time, if I wake up before 11 o'clock, then there can be two more today, if you wake up after 11 o'clock, then it is estimated that it will be two more tomorrow, because the time difference is reversed, the spirit is really bad during the day, I only wrote nearly two chapters today, and I fell asleep, and the remaining words were written when I woke up, so it depends on when I wake up, either two more today, or two more tomorrow.) ）

Yun Qingqing's investigation has no rules at all, in fact, she herself can't tell what the methods and rules of her investigation are, she seems to think that there may be here, there is a great possibility here, there must be something like this, in her words, this is likely to be her memory, but it has not been obtained yet, but it can be used instinctively, and how it is analyzed and confirmed, even she can't know, or she knows but can't say.

Hao Qi naturally believed it, according to Yun Qingqing's performance these days, his questions, whether it involved martial arts, various experiences, or even the truth of history, as long as she knew it, she would tell him for free, and she would say it in great detail, even if she kept showing an impatient expression, but what she said was not impatient at all.

In this case, the two began to dig down after five days, this excavation method is very similar to the type of tomb robbery that Hao Qi knows, both of them dig down obliquely, although the two do not have the right tools, but both of them are in the realm of internal force, as long as they want to, the excavation speed can be much faster than a professional drill or something, but this is the third layer of the underground world, in order to avoid too much movement, the excavation speed of the two is controlled and controlled, but in less than three days, the two have dug down a passage of nearly 100 meters, until this depth, the two finally dug something special for the first time......

It was a metal wall shell completely made of internal force alloy, I don't know how thick it was, the two of them couldn't even break this wall, and even Yun Qingqing's giant gun could only slowly carve holes in it, and it took most of the day to dig down a brick-sized piece, and the thickness of this wall may be calculated in meters, if you want to get through, and open up enough empty space for two people to enter, I don't know how much time it will take.

So the next two people are digging around this internal force alloy wall, according to the strong development of the ancient internal force civilization era, even in this underground three-layer world, it is impossible to build a turtle shell, either the entrance is hidden, or there is no entrance, this is impossible, so there must be an entrance, and it is estimated that it will not be too hidden, the two only need to dig there.

And on the third day after the excavation began around the metal wall, both of them felt danger, an indescribable premonition of danger, which came from nowhere, and as the excavation continued, the premonition of danger became stronger and stronger, so that both of them decided to stop digging, but the day after they stopped digging, the premonition of danger did not disappear, but continued to increase.

“...... So there are two possibilities. ”

Yun Qingqing said to Hao Qi with a serious expression: "One possibility is that our excavation tried to enter the ruins and woke up the terrible monsters in this ruins, or the defense system inside this ruins is activating, and those internal qi realm puppets will come to attack us, in short, there are both possibilities, after all, if this ruins really experienced a great destruction, then it is not uncommon for any terrifying existence in it......"

"There is another possibility, and that is that danger is approaching us from afar. ”

After hearing this, Hao Qi pondered, and after a moment he said: "Both are possible, the danger inside, even if we stop digging, but it may have woken up, or half awakened, and can feel us, and this feeling of increased danger is likely to be the speed at which it wakes up...... The second possibility can't be said to be none, after all, your brother is still alive, and he is also in this underground three-layer world, God knows if he has any ability to track us thousands of miles, which is also very possible......"

"I didn't say it. Yun Qingqing glanced at Hao Qi and said dissatisfiedly: "Then do you think that is more likely?" To tell the truth, this is the third layer of the underground world, we are really lucky, we have not encountered real danger along the way, but this does not mean that we can live in this underground three layers of the world, this time the excavation of this ruins is actually just to try your luck, if you think that the threat in this ruins is more likely, then we will leave immediately, far away from here, we can always avoid this danger, otherwise, then we will continue to dig, before the distant threat comes into the ruins, this time you choose。 ”

Hao Qi wanted to smile bitterly, of course, if the object was a girl, it should be fine...... But in this case, he could only say solemnly: "I think so...... Your brother is more threatening! Compared to your brother, even if we are dealing with a tyrannical creature, if we have a premonition of danger in advance, and can prepare in advance, we are much more likely to escape than when we met your brother, don't you think so? I don't know where the danger comes from, it may be in the ruins, or it may be that your brother has tracked us, this is a five-fifty thing, so in the case of the possibility of both, we choose a more convenient option to survive, we ...... How do you feel about continuing to excavate this ruin?"

Yun Qingqing thought about it carefully, she finally nodded and agreed, just like that, the excavation work began to continue from the next day, and with the gradual increase in the sense of danger, the two of them not only excavated much faster, Yun Qingqing also added a lot of escape preparations around this excavation site, including routes, props, blocks, and even a small underground passage, no matter what, Yun Qingqing has prepared all the escape routes that may be needed.

Then, they dug into the gate area......

At the same time, on the other side, the huge flame lizard was lying on the corpse of a huge leopard-like tyrannical creature, constantly devouring the flesh and blood of the corpse of this tyrannical creature, and as it devoured more and more flesh, the scars and blood stains on its body were almost healing at a speed visible to the naked eye, and this healing speed even exceeded the recovery speed after Hao Qi injured it at the beginning, even if it was a tyrannical creature, this recovery speed was exaggerated......

No one had ever thought of it, and perhaps even Yun Qingyuan, who had an incomplete memory, that after the steel needle pierced into the brain of this flame lizard, although it later withdrew the steel needle, even if it was no longer controlled by the steel needle, but it did not die, what kind of amazing changes did it have......

In fact, if an expert conducts an autopsy on a person who has been controlled by a steel needle and then dies violently, it will be very clear that these corpses are beginning to collapse from the inside, but this collapse is very strange, not because the body can not bear huge power, but because the body consumes too much life force, and suddenly too many chemicals are produced in the mind, if you have to describe it, then the body suddenly begins to evolve, nutrition can't keep up, the body can't bear it, and the result is the sudden death of the person......

And even if the human being who was rescued and did not die, because of the tempered body, he would naturally close this self-limit consumption and prevent the body from collapsing from the inside......

But if the physical body suddenly evolves and liberates the restriction switch of the body, such a physical body is not human, but a higher-level creature with a super-strong physical body that is far beyond human imagination, a super-strong recovery and healing power, and a hundredfold, thousand-fold, and ten-fold human vitality, but it is not like a human being who has tempered the physical body and can close itself off from this change...... The result?

The Flame Lizard devoured the corpse of this giant tyrannical creature, and it did not suffer any fatal injuries, on the contrary, judging from the battle scene, it almost completely suppressed the battle of this tyrannical creature, and finally killed it, the difference in strength between the two sides was too great, just like the Flame Lizard not long ago and it is now......

It's evolving, and it's evolving faster and faster...... (To be continued.) )
