After entering the iron tower, Lin Feng directly arrived at the place where they had escaped before, and according to what Bing Lao had said to himself before, he came to the bottom of the valley with ease, this is a secret passage of the mechanism, unless it is a coincidence or someone deliberately leads, otherwise it is impossible to find here.

At the beginning, the people of the four major sects were stationed here just to collect some treasures, but I am afraid that they would not think of this if they wanted to break their heads.

"Let's go, I'll take you to have a look!" Lin Feng touched the huge head of the Netherfinary with his right hand.

Roar!

A loud roar from the Nether Sparrow continued to echo in the secret passage, and after entering the secret passage, Lin Feng now naturally did not need any lighting things, but everything around him was clearly perceived.

According to his memory, Lin Feng came to a secret base that he had discovered, and soon a stone gate hundreds of meters high appeared in front of him, Lin Feng tried his best but could not shake the stone gate at all, but now his strength is no longer the little boy he was at the beginning.

At this time, after looking at the relief on the stone door, the ghost bird subconsciously took two steps back, and carved a real dragon and a real phoenix on the stone door, and the lifelike appearance even the relief gave people a sense of daunting.

The true dragon and true phoenix are the highest creatures that exist between heaven and earth, they rule the entire spirit beast clan, it can be said that few creatures can compare with it, and although the ghost finch next to him has the blood of the ancient immortal bird, unless it can truly transform into an ancient immortal bird, otherwise it will never be able to suppress the fear in the body.

"Tut-tut......" Lin Feng couldn't help but sigh, this kind of might and domineering was by no means comparable to that in an ordinary group.

In addition to the largest true dragon and true phoenix, there are many strange creatures depicted not far away, some with sharp beaks and fangs, and some with ribbed wings, it can be seen that these guys are by no means good, and it is not an exaggeration to say that these creatures are much stronger than the ghost sparrow beside him.

"It's really hard to imagine who the builder of this stone gate is, who can carve so many things that shocked the world!" Lin Feng couldn't help but admire, you must know that it is impossible to carve so many divine beasts based on imagination alone, it is obvious that you have not really seen it before you can depict it vividly, if you guess correctly, the carving on the top of the door seems to be a kind of record at this time.

There are many stone pillars around the stone gate, and the voice of this stone pillar has some ancient words written on it, these words are some ancient fonts, which are completely different from today's fonts, Lin Feng has not seen the reason for looking at it for a long time, even the memory of the Venerable One has no record of these words.

And the most conspicuous thing in this hall is a lantern in the sky, the lamp does not know how long it has been on, I think it has been a thousand years, but in this thousand years of time, it has not hesitated to extinguish, a small lamp is enough to show how big the other party is.

I am afraid that this palace is also the relic left by a certain strong man, who may have been strong enough to be invincible on one side, and finally found a piece of feng shui treasure land to become their final home.

Of course, this periphery is just a shock, but there is no substantial treasure, if you want to scrape something, I'm afraid you have to do a little bit like the stone gate.

But now he wasn't sure that he would be able to open the stone door, but there was nothing wrong with trying, if he couldn't even open it with his current strength, then I'm afraid the treasure inside would be extraordinary.

"Nether Sparrow, your strength is great, you can try to see if you can open this stone door!" Lin Feng glanced at the Nether Sparrow on the side, you must know that in terms of pure strength, the guy Yue Fei is comparable to a strong person of the same level, and what humans are good at is more dexterity, unless it is some strong people who are born to cultivate the physical body, otherwise, it is impossible to compare with the spirit beast in terms of strength.

Hearing this, the Nether Sparrow retreated, but in an instant, his legs exerted force, and then the huge claws slammed into the straight door, that kind of violent power Even Lin Feng couldn't help but take a step back, I heard that if he was really going to be topped by this guy, he would have to shed his skin if he didn't die.

Boom Boom.

I heard a loud noise, and even the periphery of the whole hall couldn't help but tremble twice, and stones continued to fall from the sky, and the dust stirred up continued to fly in the air, and after the dust settled, the Netherbird stood quietly in place, but the huge stone door was still intact in place, and not even a little scum was scattered.

Roar Roar Roar .........

Seeing this, the Nether Sparrow slammed even more violently, but after a few impacts, it became clear that there was a trace of blood on the huge claws, but the stone gate was still motionless!

"No wonder there is no real difference between animals and humans in this world, although they look different from each other, and even have a certain gap in behavior, but their wisdom is indeed not bad, especially after the spirit beast breaks through to the level of Xuanhai, it can give birth to the wisdom of real humans, and after that, it is an adult beast, and at that time, if it is not deliberately noticed by the real powerhouse, they can be completely hidden from humans!"

Rumble......

But just when he was slightly distracted, he only heard a shocking noise in the cave, and after seeing that it couldn't be opened for a long time, it also completely aroused the beastly nature of this ghost sparrow, and it actually directly hit the stone gate with its own body, but it was a pity that the moment his body came into contact with the stone door, the huge body was directly knocked out, and then fell the ground.

Roar.........

Even though it was covered in bruises at this time, it still didn't give up, and when the huge body stood up, it continued to stare at the huge stone gate with the beast's pupils, because their skin was rough and thick, and even if they were injured, they were not as sensitive as humans.

Taking advantage of this situation, Lin Feng didn't dare to let this crazy guy continue to attack Shimen, he stepped forward to block the Nether Sparrow and said, "You take a rest first, I'll come!"

Hearing this, the Nether Sparrow on the side thought about it, and finally dragged his tired body to the side, now even he was extremely curious about what was behind him, Lin Feng's strength was above him, and he didn't know if he could open this heavy stone door.

call

Lin Feng took a deep breath, his eyes stared at this huge stone gate without blinking, according to rumors, this is an extremely mysterious place, even Dongfang Han doesn't know about the existence here, only their old guys know about this place, but with their strength at that time, they couldn't open this gate at all, and now that they think about it, it is true, according to his current estimate, the strength of the two elders of black and white should be in the appearance of the Xuanhai Triple, and its strength naturally cannot be the opponent of the Nether Sparrow.

Thinking about it, the Burning Sun Sect was indeed weak at the beginning, and the strength of the Taishang Elders was not as good as the elders of other sects, and it was indeed inevitable to be at the bottom, so they would become a victim in the end, but fortunately, they had a unique vision, and only then could the Burning Sun Sect see the light of day.

I saw Lin Feng's five fingers together, and then gathered all the aura in his body on the Dao fist, and the power of this punch was enough to beat a Xuanhai triple powerhouse hard.

"I don't believe I can't break a broken stone for you!"

As soon as the words fell, Lin Feng even jumped up, and then smashed his fist the huge stone gate stone.

In an instant, a loud bang echoed throughout the hall. However, this time there was finally a trace left on the huge stone gate, but this stone gate was like a spring, when Lin Feng came into contact with it, he only felt that a thrust was also transmitted to his fist, and in an instant, Lin Feng's body retreated uncontrollably.

"Dark power!"

Lin Feng was slightly shocked in his heart, obviously this stone gate was not as simple as an ordinary stone gate, and someone should have touched it on it.

"Then go on!"

As he spoke, Lin Feng punched towards the huge stone gate again, this time he used more strength than before, but Lin Feng still wouldn't use all his strength until he figured out the doorway.

After a loud bang, Lin Feng was instantly bounced out, and then blood continued to drip down from his fist.

hiss

That huge rebound force even Lin Feng couldn't help but gasp, after two attacks, he found that the greater the force, the stronger the power of functional feedback, in other words, if you want to open this stone door, you must withstand this terrifying impact, and this terrifying impact is exactly the same as your own strength.

"It's weird!"

Lin Feng tried several times in a row, but the result was the same every time, and after a few points of competition, Lin Feng also stopped attacking, obviously relying on brute force alone may not be able to open this stone gate at all, unless it is really those peerless powerhouses, they can directly destroy their concealment power.

"If you want to be strong, you will be strong, and when you are weak, this kind of thing is really the first time I have seen it!" Lin Feng kept thinking about it in his mind, but he couldn't think of a reason for a long time, how could a hard stone have a rebound power? This is really too unbelievable to say, but the facts are in front of him, and he has to.

Time passed minute by minute, Lin Feng was not in a hurry, and suddenly at a certain moment, his eyes widened suddenly, and he remembered a thing in his previous life, called non-Newtonian fluid.

That kind of thing is strong when it is strong, and weak when it is weak, but this stone gate has something in common with that thing.

Since the brutal strength is unable to open it, can it use the power of the outside world, thinking of this, Lin Feng didn't care about the sharp pain in his hand, and once again punched towards the huge stone gate, but he was pleasantly surprised to find that under a certain degree of strength, the sharp pain coming from the fist this time was not as fierce as before.
