Lin Jiu naturally didn't know what happened in Jinguang Temple, of course, even if he knew, he wouldn't care.

At this time, he was intoxicated by the mystery of the Nebula Sword Technique.

When his primordial spirit sank into the book in his hand, in front of his eyes, an incomparably vast galaxy emerged.

In the galaxy, every flickering starlight is a beating sword light.

Every time the sword light danced in the galaxy, Lin Jiu could feel that there was also a faint rhythm in his primordial spirit and mana, which was faintly in line with the beating sword light.

As long as you can grasp this rhythm, a sword trick can be regarded as entering the door.

But when he tried to grasp the rhythm, he couldn't, as if the wonderful rhythm never existed.

For this, Lin Jiu was not in a hurry.

As an alternative method of the integration of law and martial arts, as a ladder of the true integration of law and martial arts, the introduction of the sword technique is not so easy - don't you see, the Great Demon of the Ten Thousand Saints Dragon King, as the Great Demon who is only one step away from achieving the spirit during the Tribulation Period, has obtained this Nebula Sword Technique for a long time, and he can't get started to successfully practice this sword technique, and he can see how difficult it is to learn this sword technique.

In fact, when more people see this sword technique, they can see that vast galaxy, which is already regarded as an outstanding performance of talent, just like Lin Jiu, who can perceive that the starlight in the galaxy is sword light, and can faintly feel the rhythm of the sword light when the sword light beats, the rhythm generated by the resonance of his spirit and spirit can be said to be unique.

Even the Ten Thousand Saints Dragon King's comprehension of the Nebula Sword Technique has not yet reached this point.

In the Yuanhua Garden, Lin Jiuduan was sitting, and while sensing the rhythm of the sword light, his fingers were also shaking unconsciously, making all kinds of movements to control the sword.

And when his fingers flicked, in the furnace where the sword was smelted in the Yuanhua Garden, the flames that Lin Jiu urged with mana were also constantly beating, like a stream of water, washing away the small nebula gold from different angles, and every time the flames washed away, there were dots of gold on the nebula gold.

Lin Jiu's aura also penetrated into this nebula gold little by little.

And so, another year passed.

……

What woke Lin Jiu up from his cultivation was the jade pan unique to Bibo Dragon Palace.

"What happened?" Lin Jiu summoned Naba Bo'er, who was wandering at the gate of the Yuanhua Courtyard.

"Shaojun, dig through, dig through." Ba Boer ran in front of Lin Jiu and said, elated, dancing with his hands.

"Through?" Hearing this, Lin Jiu's spirit couldn't help but be shocked.

What Ba Bo Erben said was nothing else, it was the retreat route that Lin Jiu had prepared for the Bibo Dragon Palace—a passage from the Bibo Dragon Palace directly to the underground water veins.

Once something happens in this Bibo Dragon Palace, the people in the Dragon Palace can escape directly into the underground water veins along this channel, and escape through the underground water channels that extend in all directions.

This waterway was not any of the ones that Lin Jiu had marked on the map before.

More than a year ago, he took the little demons of Bibotan to survey the water veins outside Bibotan with great fanfare, Lin Jiu knew that it was absolutely impossible to hide from others, and the passages and directions he marked on the map were just used to hide people's eyes and ears - the real retreat of Bibotan was a passage that made Ben Bo Erba dig directly from the underground of the Dragon Palace to the underground river after he returned to the Dragon Palace.

Because of the fact that the construction started at the same time as other hidden passages, and the reason for covering up the movement, even if the little demons who excavated the passage used their demonic power, it took a year to dig the passage.

"Let's go, take me to see it." Lin Jiu got up and moved his body.

The entrance to the escape passage is located under the Lang Xuan Treasure Tree.

The Langxuan Divine Tree, one of the legendary sacred trees, can gather vitality and purify vitality, but it has long been extinct between heaven and earth.

And this Langxuan treasure tree in the Halloween Dragon Palace has nothing to do with the legendary Langxuan Divine Tree - it is a dead branch obtained by chance when the Halloween Dragon King travels during a trip, and after the Halloween Dragon King gets this dead branch, he perceives that there is still a glimmer of life inside, so he brings it back to the Dragon Palace and cultivates it carefully, and finally this dead branch sprouts and grows into a small tree, with a special magic circle, it can gather the vitality between heaven and earth, similar to the legendary Langxuan Divine Tree, Therefore, the Dragon King of All Saints named it Langxuan Treasure Tree.

The reason why the Ten Thousand Saints Dragon Palace was able to gather vitality was that in addition to the magic circle deduced by the Ten Thousand Saints Dragon King, the existence of this Langxuan Treasure Tree was also a condition that could not be reproduced.

Before the retreat, the Ten Thousand Saints Dragon King entrusted the affairs of the Dragon Palace to Lin Jiu, and naturally told Lin Jiu about the existence of this Langxuan Treasure Tree.

This Langxuan Treasure Tree is not an exaggeration to say that it is the most precious treasure in this Ten Thousand Saints Dragon Palace.

Lin Jiu chose to retreat here, naturally for safety and concealment.

If one day, the Ten Thousand Saints Dragon Palace is really in a desperate situation, then the enemies besieging the Ten Thousand Saints Dragon Palace will never think that the retreat of the Ten Thousand Saints Dragon Palace is hidden under the Langxuan Treasure Tree - after all, as far as normal people's thinking is concerned, such a precious thing as the Langxuan Treasure Tree, after taking root and sprouting, it is too late to take care of it, and the people who have obtained the Treasure Tree are afraid that they are eager to keep the environment around the Langxuan Treasure Tree in a state suitable for the growth of the Langxuan Treasure Tree permanently, and how can they break ground around the Langxuan Treasure Tree, Causing changes in its surroundings?

However, Lin Jiu, who knew from the mouth of the Ten Thousand Saints Dragon King that the true environment in which the Langxuan Treasure Tree grew was the spiritual grass that had formed a formation all over the Ten Thousand Saints Dragon Palace, naturally had no such concerns.

After consulting the advice of the Ten Thousand Saints Dragon Mother, he was very decisive in ordering Ben Bo Erba to bring people to start construction under this Langxuan Treasure Tree.

The entrance of the waterway is not big, only more than three feet, under the cover of the scattered roots of the Langxuan treasure tree, it is extremely inconspicuous, and there is no trace of formation illusion in the meantime, even if someone comes to see this entrance, they will only think that this is an ordinary gap in the water.

Standing at this entrance, Lin Jiu could clearly perceive the water vapor rising up along this entrance.

This comes from the water vapor in the underground dark river, and the water vapor in the blue wave pool, which is naturally different.

The water vapor in the blue wave pool is more warm and moist, and it is more 'popular', just like a piece of warm jasper, and the water vapor that comes from the underground dark river is more cold and cold, like a cliff iceberg that rejects people thousands of miles away.

However, this is not a problem, after a period of time, this blue wave pool and the underground river below will be completely integrated, and the difference in water vapor between them will naturally disappear.

"Have you ever investigated the following situation?" Lin Jiu glanced at Ba Bo Erben beside him.

Ba Bo'er Ben stopped sideways, and then said to Lin Jiu again. "Running around, it's dark below, and you can't see anything clearly."

Ben Bo Erba and Ba Bo Er Ben are blood brothers, and the bloodline inherited in their bodies has its own mystery, which can enable them to transmit information within a certain distance, so although Ben Bo Erba and his talents have just dug through this waterway, and they have not returned to the Dragon Palace, Ba Bo Erben has already used the jade rock of the Dragon Palace to wake up Lin Jiu in advance, and brought Lin Jiu to this waterway.

"Can't see anything?" Lin Jiu immediately became interested.

Monsters are different from human races - no matter how weak the monsters are, they are also monsters, they are non-human beings with mana and divine sense, and they see night as day, which is just an ordinary thing for monsters, and it can make a monster feel black and can't see anything, which is enough to show that the underground river under the waterway is not an ordinary place.

"You keep this place, I'll go down and have a look." Lin Jiu commanded Ba Bo'er, and as soon as he was short, he went all the way down the waterway.
