It looks like a building, but to be precise, it is a door connected to the mountain, three feet high and two feet wide, and the door frame and façade are covered with dark gold intricate rune ancient characters, which looks extremely mysterious.

The door was closed and looked like a sleeping beast, ready to open its eyes at any moment.

"This is ......!"

Behind Ye Xiaochai, he suddenly remembered the exclamation of the old man, and as soon as the old man finished speaking, he took a few steps quickly, wanting to get closer to see.

Ye Xiaochai didn't feel anything wrong, so he let the old man look at it at will, it was best to see why, that would save a lot of thought.

I saw the old man frowning, standing in front of the door, his eyes kept looking up and down, and the unknown ancient text on the door was densely packed.

Ye Xiaochai took a step forward, stood beside the old man, looked up at the strange door, and asked, "Can you see the strangeness in the flower friends?"

The old man's originally focused face was slightly moved when he heard this, and then he turned his head and said to Ye Xiaochai: "If the old man is not mistaken, this should be an extremely rare Sumeru forbidden method. ”

"Sumeru Forbidden Method!"

Ye Xiaochai hugged his chest with his right hand, held his chin with his left hand, and muttered to himself.

At this moment, the old man raised his hand and at the same time pinched out a spell, and a simple fireball immediately appeared in the air above his palm, and he hit the door.

At the moment when the fireball hit the door, the fireball was extinguished silently, leaving not even a faint trace.

"That's right, the old man once saw an introduction to this door in an ancient classic, and now the two are compared with each other, and it is very likely that this is the Sumeru forbidden method. The old man said excitedly.

"I have shallow experience, I have never heard of the forbidden method in Sumeru, and I hope that Taoist friends will solve one or two doubts!" Ye Xiaochai clenched his fists and solemnly asked.

"Hehe, in fact, it's nothing, I don't know, how much do you know about the mustard seed space?" The old man smiled and asked Ye Xiaochai rhetorically.

"Mustard Seed Space!"

Ye Xiaochai was slightly surprised, and he didn't understand why the old man asked him this, so he smiled bitterly and said: "This is the art of space! ”

"That's it! The old man will briefly say to Daoyou, this so-called mustard seed space is actually a node that opens the space, and then refines it into an independent space, to put it simply, it is equivalent to the storage bag used by our immortal cultivators, but the storage bag is too low to be called mustard seed space, the real mustard seed space, and even a manor can be placed. "The old man said a little bit about the introduction of the mustard seed space.

"Open the space! If you do this, won't it lead to the outside of the interface?" Ye Xiaochai felt a little incredible.

"Outside the interface....... The old man smiled bitterly, and then said: "Daoist friends have been thinking a lot, how to refine this mustard seed space, the old man still doesn't know, but the old man can be sure that in the entire Holy Heaven Continent, no one has the ability to break through the space, unless several hidden God Transformation Stage seniors work together to attack a space node, maybe it is possible to break the space, of course, this has to exclude those who hold the treasure of breaking the boundary in their hands." ”

After hearing this, Ye Xiaochai nodded in understanding, for breaking the space, if the space crack that had almost killed him could be understood as breaking the space, then he had seen too much, and he almost felt numb to that kind of thing.

Thinking so, he unconsciously pulled the spatial crack and the mustard seed space together in his mind, so he asked the old man this question.

After listening to Ye Xiaochai's question, the old man just smiled bitterly and said: "Although the old man has never seen this space crack, he has also seen some from the classics, according to legend, this crack can tear everything apart, even the Yuan Infant Monk can't escape, but whether it is related to the mustard seed space, this is unknown." ”

"Okay, then what is the connection between this Sumeru Forbidden Method Gate and the mustard seed space?" Ye Xiaochai stretched out his hand and pointed to the door in front of him, and asked the question again.

"Hehe!" the old man heard this, first showed a mysterious smile, and then said: "The space inside the Sumeru Forbidden Method Gate is called the mustard seed space, and there is another one called the mustard seed magic method, and the space inside is called the Sumeru realm, Sumeru hides mustard seeds, and mustard seeds contain Sumeru, so there is a certain connection between the two, but if one of these two doors is used, the space there must be extremely large." ”

"Oh! Sumeru Forbidden Method, Mustard Seed Wonderful Method!" Ye Xiaochai felt a little unbelievable when he heard it.

"In fact, the mustard seed space can be called the Sumeru realm, and the Sumeru realm is also the mustard seed space, but the name of the Sumeru realm was only flourished in ancient times, and now only some ancient classics are left to record. ”

Just after the old man finished speaking, Bai Hong and Hua Feiwu also walked in from outside, standing behind the two, and the two pairs of beautiful eyes looked at the door that they had never seen before.

"Okay! Since Daoist friends know this Sumeru forbidden method, they must also know the method of opening the door!" Ye Xiaochai nodded, talking about opening the door.

"It's also a shame that this is the Sumeru forbidden method, and although this door is thick and can ban all spells, as long as you use brute force, you can push it open, if you encounter the mustard seed magic method, the old man is powerless. After the old man finished speaking, he took off a spirit beast bag from his waist, and then said: "Daoyou and let me go, the old man has a Li Niu rhinoceros spirit beast here, this beast has no other skills, but it is particularly rough and thick, and there are still two handfuls of strength." ”

Ye Xiaochai didn't object, and moved a little farther away, and Bai Hong and Hua Feiwu were also a little farther away.

I saw a giant beast fall heavily on the ground, making a "boom" sound, Ye Xiaochai's eyes fell on this beast, and found that it was a spirit beast with fourth-level peak strength.

The head of this beast is as big as a bucket, with three short horns that soar to the sky, its body is more than three or four feet long, and its limbs are even thicker, and it has more than enough to rub its huge body, and its body is covered with black scales the size of a fist, and it looks like it is indeed infinitely powerful, but its tail is slightly shorter.

The old man raised his hand and pointed at the Sumeru Forbidden Method, and saw a roar like anger coming out of the beast's mouth, and then he climbed on all fours, and the ground he stepped on "bang" sounded, and he slammed into the door with all his might.
