"But in this world, how can there be so many suitable magic weapons for you to replace? After you replace the new magic weapons, should you get familiar with them again?

"When you spend a few years or decades to familiarize yourself with the newly replaced magic weapon, maybe your cultivation level will be broken again, and the familiar magic weapon you just knew is not suitable for use. So, should you continue to change magic weapon?

"It's better to add some new materials to the magic weapon you already use, and then upgrade it. Only in this way can the magic weapon you grow up with will allow you to exert your power when fighting against the hostilities!"

Xu Xing nodded slightly when he heard this, and felt that his words were very reasonable.

However, Xu Xing's cultivation has just been upgraded to the foundation-building realm, and he does not feel this way for the time being.

When in the Qi refining realm, Xu Xing often felt that it would be more difficult to control several flying swords at the same time. After reaching the foundation building realm, he felt much more relaxed.

Now the magic weapon Xu Xing possesses, whether it is the five external swords or two sword pills, feels that it is not light or heavy, and it is just right.

As for the other two water-type and wood-type sword pills given by Shen Yuanqiu, as well as the fire-type sword pills in front of him, they were all just obtained not long ago, and Xu Xing had not yet sacrificed and refined them, so they were not included.

After Xu Xing put away the sword pills, he thanked the old man. When he was about to leave, the old man said, "By the way, in half a year, a secret realm will appear. Do you want to go or not?"

Xu Xing stopped and asked, "Secret Realm? What kind of secret realm? Is it the same as the small Five Elements Secret Realm used for testing when recruiting disciples in the sect?"

The old man waved his hand and said, "Not that kind! The so-called small five elements secret realm is actually artificially created. The space inside is too small, it's nothing! What I'm talking about is that kind of natural secret realm!"

Xu Xing was a little puzzled: "The real secret realm?"

The old man said, "No! Have you heard the sayings of the big world, the middle world and the small world?"

Xu Xing nodded and said, "I know a little bit about it. According to legend, there will be three thousand worlds in each big world, and there will be three thousand small worlds in each big world."

The old man said, "Yes, there is such a saying. But the so-called number of three thousand is actually just a general reference. Some of the different worlds and the worlds of the middle thousands may have more than three thousand, while others may have less than three thousand.

"In addition, not all the worlds of the Great Thousand Worlds contain the Middle Thousand Worlds, and not all the Middle Thousand Worlds contain the Small Thousand Worlds.

"There are more mid-thousand worlds and small mid-thousand worlds, which are actually not in the mid-thousand worlds. Most of them are just gravitational in the Great Thousand Worlds and the Middle-thousand worlds, and surround the void around the Great Thousand Worlds and the Middle-thousand worlds.

"You may not know yet, but the world we live in is a world of thousands."

Xu Xing said in surprise: "The world we are in is just a world of mid-thousands? We can already practice to the realm of transforming the gods. I thought this was the world of great thousands!"

The old man said: "The Great Thousand World can be practiced all the way to the ascension of the Immortal World. Our world cannot do it. After transforming into a god, you need to go through nine thunder tribulations and thunder tribulations before you have the ability to leave our world and go to the Great Thousand World."

When Xu Xing heard this, he felt that the realm after the transformation of the god seemed to be different from the realm he learned through the novel of immortal cultivation in his previous life, so he asked: "Uncle Grand Master, shouldn't he be in the realm of refining the virtual world after the transformation of the god? How could it be a thunder tribulation?"

"Refining Void? What realm is that? I haven't heard of it!" The old man looked down upon and explained to Xu Xing: "The realm of transformation of the god is actually the primordial spirit that has been achieved initially after the Nascent Soul grows up.

"But when the Yuanshen is in the realm of transformation, he is still an Yin God. In the process of action, there are Yin energy, heavenly wind, scorching sun, thunder and lightning, which can damage the Yuanshen. Only by experiencing a special thunder tribulation and allowing the Yuanshen to absorb the most yang energy contained in the thunder tribulation will he slowly fade away the Yin energy and become the Yang God.

"Only the realm of Yang God can you not be afraid of the scorching sun and wind in the sky, break through the world's diaphragm and reach a higher level of world."

Xu Xing heard it a little out of his mind, and asked curiously: "So... what level should the monks in the small thousand worlds be able to leave the world they are in?"

The old man said: "In the small thousand world, there are too many laws of the great way, and at most people can only practice to the Golden Pill realm. After reaching the Golden Pill realm, if you want to continue practicing, you must overcome the thunder tribulation and ascend to the Mid Thousand World similar to our world."

Xu Xing said in surprise: "The golden elixir monks in the small thousand world still need to overcome the tribulation? I see that my master has condensed the Nascent Soul and has not experienced the thunder tribulation!"

The old man said calmly: "That's because we are in the Mid Thousand Worlds. Didn't I just say that? After the realm of transformation, we need to go through nine thunder tribulations. These nine thunder tribulations are a test for our monks in the Mid Thousand Worlds to leave this world. If we can pass the thunder tribulations, we can leave. If we can't pass, we will be struck by the thunder and the soul will be dissipated, and our cultivation will be transformed into the spiritual energy of heaven and earth again!"

Xu Xingdao: "Did the golden elixir monks in the small world have similar situations when they experience thunder tribulation?"

The old man nodded and said, "That's right! However, there are no monks in many small worlds, and their spiritual energy is very thin. Even if there are occasionally a few small worlds that can be practiced, which can make people practice to the perfect golden elixir and reach the standard of ascension, they may not necessarily be able to reach the Zhongqian world after leaving the small world."

Xu Xing said in surprise: "Why is this?"

The old man explained: "I just told you that many small worlds are not actually connected to the Zhongqian world, and they are not within the Zhongqian world. More of them are actually being gravityed by the Zhongqian world and surrounding the Zhongqian world. The distance between them and Zhongqian world is also far and near. After the Jindan monk ascended, he will be teleported by the world power of the Xiaoqian world and may safely arrive at Zhongqian world.

"But if there are golden elixir monks who are far away ascend to those small worlds, the power of the world may not have enough power to teleport them into the Zhongqian world. More likely, they will fall into the void turbulence, die in the void cracks, or die in the void beasts. Only a very small number of lucky people can reach the Zhongqian world."

Xu Xing asked with some concern: "Then... will our world encounter this situation after ascending in the future?"

The old man smiled and said, "This is not necessary. The monks in the Yangshen realm have already had enough self-protection ability in the void to cross the void. After ascending, many powerful monks will not choose to teleport directly to the Great Thousand World, but will travel through the void, increasing their experiences and going to the Great Thousand World."

Xu Xing breathed a sigh of relief: "That's good!"

The old man raised his eyebrows and said, "You are a little monk who just built a foundation, but you are worried about the Yangshen realm. Are you thinking too far away?"

Xu Xing scratched his head and laughed: "Learn more knowledge, so you can make some preparations for your future plans!"

The old man said, "This kind of preparation usually begins when you reach the Nascent Soul and the God Transformation Realm. Even if you want to prepare now, it is not reachable. I tell you that the matters of this big world, the middle world and the small world are mainly to explain the secret realm to you."
