While holding such doubts, Zhou Ran put his hands on the door to exert force, he had already noticed the iron ring on the door, so he guessed that the door should be pulled, not pushed, just like he thought, both hands pulled the iron ring, dragged it out, and it was very difficult to pull the door with Zhou Ran's strength of 30 points.

He grabbed this iron ring with both hands, and held the Dao Dao green tendons on his two arms, these meridians were like a giant python hidden under the skin and climbing fiercely, in an instant, he gathered all the tendons, and at the same time burst out a large amount of internal qi in the body, in this short half a minute, although Zhou Ran's strength on the panel was still 30 points, but thanks to his unique power skills and the strong internal qi in his body, the strength he exerted was at least about 45 points.

There was a low roar in his mouth, Zhou Ran took a step back violently, and opened the door open, only a gap that could accommodate one person to pass through, seeing the appearance of this gap, he slowly let go of his hands, but when he wanted to let go, he found that his hands were still holding his head tightly, and smiled helplessly, the strength he had just made was too great, a little cramped, he had to keep moving his hands slightly, until 5 minutes later, the two arms felt a little better.

Although there was no backlash, when he exploded his strength just now, the strength he consumed was not the same as when he gave the demon wolf the last stab.

Looking at this gap in the door, Zhou Ran rubbed his chin, thought for a while, and turned around and left the top of this huge building, a dark eye full of faint essence, staring at Zhou Ran, who was leaving quickly, had a puzzled look on his face.

Zhou Ran didn't run away directly, he returned not far away, dug up the piece of magic iron that was about half a person high from the ground, and then ran back to the gate of the building with the magic iron, he first passed through the gate, and then put the magic iron on the gap in the middle of the gate, although this piece of magic iron is only half a person high, but if you lie down, the width is almost exactly the same as a person, and this gap can be perfectly stuck.

And the magic iron only has a little bit of demonic energy in it, and it can be evaluated as a Hong-level material, mainly thanks to his strength that far exceeds that of ordinary metal, if there is any mechanism in this gate in the future, it will automatically close after people come in or turn around in it for a while, then this piece of magic iron should be able to give him a little extra time, with a little extra time, the probability of Zhou Ran running out is a little greater.

I have to say that Zhou Ran, who is not going crazy, is still very alert, and after making sure that there is no problem with the magic iron, he tidied up his backpack, and then put his left hand on the handle of the water-splitting knife, and slowly moved towards it.

By the way, the water division was stored by him in one of them, the scabbard of the bronze long knife, but unfortunately this scabbard and the water division are not very suitable, resulting in Zhou Ran's very good ability to draw the knife and slash the ability to use it.

The whole building is empty, and the degree of darkness is almost the same as the outside, but the key is that there is no kind of glowing soil in the building, so Zhou Ran can't see directly after coming in, and when he is at the door, he can also use the light outside to observe the situation inside, but he only walked about 10 steps along the door, and then turned around and found that he couldn't even see the door.

For ordinary people, they may feel scared, and then they will go back down the same way cleanly, and this method can also retreat to the position of the gate normally, and if you run away directly, you may be able to save your life, but it is not a big problem for Zhou Ran, only 30 points of physique, it is indeed impossible to reach the level of night vision, but compared with its perception ability, the physique attributes and visual ability are several grades stronger.

If you divide the various hidden attributes of Zhou Ran's body, then his perception ability is definitely the best among them, Zhou Ran slowly closed his eyes, anyway, he couldn't see anything when he opened his eyes, and closing his eyes could help him immerse himself in his mind even more.

Swallowing the unique breathing method in the killing knife, Zhou Ran felt that his perception had improved again, and there seemed to be a unique visual environment, it felt like it was constantly releasing ultrasonic waves outward, and then according to the rebound of ultrasonic waves, it detected the basic structure of the entire building, it could clearly feel that about 5 meters away from its left front was a wall, and only two or three meters on its right hand side might be a seat.

Zhou Ran didn't hesitate at all, he took two steps towards the right hand, and then reached out to the position, accurately touched the position of the back of the chair, and really nodded, Zhou Ran had a smile on his face, and his perception ability was greatly strengthened in this building for some reason.

In this case, Zhou Ran no longer hesitated, he took a step and walked towards the depths of the building, there is nothing unique on the first floor of this building, it is a very empty hall, there are some scattered tables and chairs in the corners and corners, basically all of them have been damaged to a certain extent, the chair he walked over just now is one of the many intact tables and chairs.

Zhou Ran turned around on the first floor for a few minutes, and explored all the first floor, there are only three rooms on the entire first floor, in addition to this hall, the other two rooms have an independent small door, and there is a rusty iron lock hanging on the small door, of course, with Zhou Ran's perception, it can't detect the rust on it, it just feels the unique feel of the rust on it through the friction of his fingers.

And the toughness of these two metal locks is far beyond the normal range, even if the water division is strengthened by 2.4 times the sharpness, it can't split these two iron locks, and with his strength is even more useless, Zhou Ran had no choice but to put away the water and walk towards the stairs.

The left foot had just stepped into the hall, the first step of the stairs leading to the second floor in the innermost, Zhou Ran's face had a very obvious look of consternation, he directly put an iron plate bridge on the spot, a pitch-black light grazed him from directly above his body, if he didn't make this action just now, I'm afraid the consequences would be very serious now.

Dodged this attack, Zhou Ran maintained this action, rolled back forcefully, and left the place, he pulled out the water, his face was full of solemn expression, and in front of him that he could not observe with vision, a tall figure wearing black armor and more than two meters tall appeared.
