After more than ten years on the mountain, you will become invincible when you come down.

Sure enough, just as Lu Feng thought, Lu Feng soon appeared on the sixth floor of Hongmeng Pagoda. The passage to the seventh floor was also opened, and the reward appeared on the table.

"Let me just say, even though I blew up the furnace, it still turned into a pill, so I should be allowed to pass..." Lu Feng said with a sigh of relief.

I was still somewhat worried just now, whether I would fail because the furnace for refining the elixir exploded...

But when Lu Feng saw the reward on the table, his whole face darkened.

Lu Feng recognized this elixir. Wasn't it the one he had just refined?

"Oh no, you guys are going too far. You take the elixir you refined as your reward. If you had known, I would have refined the elixir with a higher quality and made nine elixirs. What a rip-off..." Lu Feng complained.

Lu Feng himself despised this elixir. Although he despised it, it could still be used to some extent. Lu Feng still put it away and walked directly into the seventh floor.

Zhang San's name on the stone tablet outside has therefore reached the seventh level.

"Damn it, who is this Zhang San? He hasn't been eliminated yet?"

"Could it be some big shot pretending to be this? This is already on the seventh floor!"

"His speed is not very fast, and it can be said that he is slower than others, but he is very stable at every level..."

"It's over, my fairy crystal, I used it to pay the bride price and hold the wedding. Now it's over, my wife is about to run away with someone else..."

Everyone was sad, one was happy, only Han Yu looked at Zhang San's name and smiled...

The scene in front of Lu Feng changed suddenly, and the challenge of the seventh level immediately began again...

When Lu Feng saw his situation clearly, he was immediately stunned again.

At this time, Lu Feng was in a formation. This should be a trap formation, and it was not an ordinary trap formation, because after careful observation, Lu Feng discovered the difference in this formation...

The surroundings are made of hard metal materials, including the feet and the top. It is like being in a small house made of metal, and the six sides are extremely smooth.

As time goes by, these six sides are slowly shrinking towards the center, which means that Lu Feng must find a way to break out of the formation as soon as possible, otherwise Lu Feng will be crushed into a meat pie as time goes by...

Lu Feng took a deep breath, concentrated his energy, and began to analyze and think about the structure and rules of this formation.

Lu Feng closed his eyes, recalled the formation knowledge he had learned, and tried to find a way to crack it.

Lu Feng activated his technique and punched the wall of this space with one punch.

With the loud "bang", the wall had no impact at all, not even a trace was left, and it was not affected at all.

Lu Feng carefully touched every piece of wall, looking for possible flaws.

But after searching for a long time, I didn't find anything special. These six walls seemed to be natural, without any flaws or loopholes...

Looking at the increasingly smaller space, Lu Feng began to feel anxious.

If this shrinkage continues, Lu Feng will have no room to survive...

Lu Feng used all his strength to press against a wall, trying to stop its contraction, but it was counterproductive, and it was of no use. Even if Lu Feng used all his strength, the wall still did not stop shrinking...

"Damn it, are you trying to trap me here?" Lu Feng complained.

But complaints are complaints, Lu Feng did not give up and continued to look for ways to break the formation...

Lu Feng frowned and thought hard.

Suddenly, he noticed some subtle lines on the ground, looming.

Lu Feng lay down and took a closer look, and found that these lines seemed to form some kind of pattern.

Lu Feng's heart moved and he thought, could this be the key to breaking the formation?

Lu Feng concentrated and tried to input the immortal power according to the direction of the lines, but the wall still showed no response.

At this moment, the contraction of space suddenly accelerated, and Lu Feng felt a huge pressure coming on him. Lu Feng gritted his teeth and resisted with all his strength, but gradually he became unable to do so.

Sweat slid down his forehead, and Lu Feng's breathing became rapid.

"Are we going to die like this?" Lu Feng said unwillingly.

Lu Feng was unwilling to give in and decided to make a last ditch effort. No matter whether he could succeed or not, he could still try, but he still needed to make continuous efforts.

Lu Feng mobilized all the immortal power in his body, gathered it in his palms, and slammed towards the ground...

The place where he hit was exactly where those lines converged. Lu Feng felt that this might have something to do with the formation...

"Boom..." There was a loud noise.

Lu Feng's power was absorbed, and then the energy was transferred out along the lines on the ground, and the lines on the ground instantly brightened...

"Crack, click, click..." This airtight floor began to crack, and other walls also stopped shrinking at this time...

At this time, Lu Feng could only bend down and huddle inside. The space left for Lu Feng was already very small...

As the side on the ground cracked, the other pieces also began to crack...

Lu Feng was overjoyed because there was a trace of bright light coming in, which meant that all these metal plates had cracked and the formation had been damaged...

Lu Feng's momentum exploded instantly, and a powerful force of energy centered on Lu Feng shot out in all directions...

With a loud "bang...", all the metal plates surrounding Lu Feng were blown away and fell apart...

Lu Feng breathed a sigh of relief. He was very depressed in that small space just now. Now that the trap was broken, he felt much more comfortable...

The scene in front of him changed. Lu Feng returned to the seventh floor of Hongmeng Pagoda. The restriction at the entrance to the eighth floor had disappeared. There was also a piece of metal fragment on the table in front of him...

"Huh? Isn't this the material used to build the trap just now? What kind of material is this? It's so hard, so what's the use of it to me?" Lu Feng asked doubtfully.

Lu Feng knew that this material was definitely not simple, but Lu Feng didn't know what kind of material it was, what its function was, and its specific value...

Although he was very confused, Lu Feng put it away for the time being. No matter whether it was a good or bad prize, it would be free if he didn't take it.

Anyway, the poor things in the fairy world may be the same as treasures in the human world. You will not suffer any loss if you keep them. What if you can use them in the future?
