The two black-lacquered doors were gone, revealing the dark cavern behind them.

"Come on, come on," a male duck's voice similar to that of a male classmate in the voice change period sounded abruptly, "Come to the old fairy." ”

Zhang Ning was suddenly taken aback, these two lingua franca of the demon clan sounded directly in his divine sense!

"What are you hesitating about, haven't you made out enough with the doormen? If you don't come here again, they will pull you into the space-time fragment again!" Seeing that Zhang Ning did not move, the owner of the voice said again in a non-hurried tone.

This time, the lingua franca of the cultivation realm was used.

Selling cute viruses and garbage coasts occupy the fragments of space-time?

...... However, it should have been this self-proclaimed "old immortal" who helped him out of the siege just now. Although it is not clear whether the enemy is friend or foe, it should be better to face this person than to face the garbage boss in Hell mode, and it is better than to be trapped in the Qiankun Treasure Snail again...... bar.

In that case, let's do it and see.

Zhang Ning clipped a talisman between his fingers and slowly walked towards the source of the sound.

The environment of the cave was similar to the ones he had passed before, except that ...... Suddenly there is nothing under your feet!

Zhang Ning fell like a turtle thrown from a high altitude by a bearded vulture towards the bald head of the Greek tragic poet.

If he hides back at this time, will he continue to fall with the gravitational acceleration of the last time he reappears next time, or will he use the position where he appeared as the initial position to start calculating the gravitational acceleration again?

...... Unfortunately, Zhang Ning couldn't detect the depth here, and he couldn't know whether the time required for this free fall would be enough for him to do the experiment, so Zhang Ning directly sacrificed the talisman "Eyebrow Flying Color Dance" - a little bit of blood turned into a rainbow, and then two white eyebrows that looked like eunuch floating dust flew up and down and appeared at Zhang Ning's feet.

After three breaths, the white eyebrows fell to the ground with a bump, and Zhang Ning raised the sleeves of his robe and walked down steadily.

The moment his footsteps fell, a white light cluster lit up in the air, which was the talisman he had just thrown into the air.

However, due to the limitation of "energy", the light will definitely not reach the limit...... That's the brightness of a 40w LED bulb.

In the dim light, the vast bottom of the cave presents a scene that only appears in a dream-

There is a thick layer of test papers on the ground, and the dense questions on it are all the legendary "know all the words, but when they are put together, they don't know what to do".

Every exam paper is complete and unravaged by graduates!

Each question unabashedly reveals the abomination of "You can get my body, but you can never understand me, and I will eventually combine with those questions that can solve 800 million troubles and produce countless high-end second-generation small questions"!

So, this must be a nightmare scene! A nightmare that every scumbag can't escape!

At Zhang Ning's feet, the test paper was undulating like a wave, looking up at him with a contemptuous and mocking face...... It turned out to be a "live" test paper!

In the middle of the cave stood a huge mountain of test papers, and on the top of the hill was a head, with a white beard but the appearance of a young man—not a single wrinkle on his face, and his skin was fair, blown-free, and free of acne.

Such a strange existence...... Could it be the legendary grading teacher?

"Hahahaha, I have advanced to the infant stage at such a young age, and I have the style of an old immortal back then~" The voice of the little duck in the voice change period matches this kind of "old and serious" remarks...... Hehe, it's really not against the peace at all.

The test papers under his feet rippled in circles, and then a wave suddenly rose and sent Zhang Ning to the bottom of the test paper mountain.

Looking closely at this normal-human-sized face growing in the test paper, Zhang Ning came to a conclusion:

Isn't this the head of the old immortal of Xudong?
