After returning from Haotian Mansion, Lin Nan returned to the martial arts arena.

The purchase limit of this immortal stone, Lin Nan suddenly felt that it made a little sense, with the improvement of his strength, now in three days, he can make up 25 million contribution points, and the purchase limit of immortal stone also proves the importance of this thing.

Meng Li still didn't agree in the end, saying that he needed to think again.

Lin Nan didn't urge, this matter was a long-term plan, the reason why he discussed with Lan Luo and then led Meng Li out was of course because Lan Luo was the only person in the entire Lin Immortal Realm who had the same idea as Lin Nan, and he was also the only one who blew up the Dragon Vein Passage.

Lin Nan believed that Meng Li would not discuss this matter alone, presumably the Jade Maiden Palace and Bi Lingxiao would soon know what decision would be made at that time, and Lin Nan could not guarantee it.

In the martial arts arena, Lin Nan once again came to the puppet of the third layer of the combination, and in the face of the overwhelming violent thunder and lightning, Lin Nan suddenly felt that he was going to win today.

But in fact, it is still a failure.

The thunder and lightning controlled by the power of the law are not something that Lin Nan can resist, and the speed of the thunder and lightning is so fast that Lin Nan is not in a hurry to dodge at all, and he is not even caught off guard by defense, let alone counterattack.

When Lin Nan withdrew from the illusion puppet, he was still shaking in place, but the paralyzing feeling from the depths of his soul had not subsided.

The contribution value has reached sixty million, Lin Nan exchanged a fairy stone in advance, and soaked in the martial arts arena for three days, exchanged the drawings of the Royal Beast Workshop, and the second immortal stone, all of which were quietly lying in Lin Nan's token.

Regarding the immortal stone, Lin Nan didn't understand very well, when the quiet and clear milky white stone was held in his hand, Lin Nan didn't feel any energy in it, just like an ordinary, but relatively good-looking stone.

Lin Nan guessed that maybe it was because of the difference in energy levels, so he couldn't feel it or absorb it.

After carefully studying the drawings of the Royal Beast Workshop, unlike other drawings, the drawings of the Royal Beast Workshop have no purchase restrictions, and they can still be exchanged in the token, and the content of the drawings also made Lin Nan understand why he could be exchanged repeatedly.

Different from other buildings in the Endless Gate, the Royal Beast Workshop is not a specific house, it just strengthens and upgrades the living environment of the spirit beasts, making this area more suitable for the living conditions of the spirit beasts, and playing a catalytic role in the survival and growth of the spirit beasts.

There are not many materials needed to build the Royal Beast Workshop, and what needs to be consumed is the spirit stones needed to depict the formation, as well as the spirit wood ore of a small number of buildings.

From the treasure house of the sect, a large number of materials were moved, and Lin Nan prepared everything and came directly to the martial domain.

As soon as he came out of the space passage, Lin Nan saw that Hao Xuan and Hao Yun, father and son, were still in the posture they had left last time, lying motionless next to the waterfall, and when they saw Lin Nan appear, they just called out respectfully, and continued to bask in the sun.

Lin Nan suddenly felt that compared with Hao Xuan's father and son, he was really diligent, and now he was setting up a rocking chair next to the two, at least Lin Nan was still moving.

Rising into the air, with the waterfall as the center, Lin Nan observed the surrounding environment, took out the drawings of the Royal Beast Workshop and did some research, and began to calculate in his heart.

The ecological environment of this martial region is maintained quite intact, with mountains, rivers and rivers, except for some buildings that imitate humans, they all maintain the original ecological scenery, and Lin Nan does not even need to do much transformation.

The maximum range of the Royal Beast Workshop is a radius of one hundred miles, the range is not large, even the core of the martial domain can only cover one-tenth of it, and the radius of a hundred miles near the immortal beast egg, the spirit beasts living in it are extremely rare, perhaps because of the default existence of this egg, so no one came to disturb.

After noting down all the locations that needed to be arranged for the formation flag, Lin Nan took out the medium-grade spirit stone from the token and began to arrange the environment first.

The location of the spirit stone needs to be buried underground, the most difficult to bury is still the underground of some mountain peaks, even if it is a retreat, it feels a little laborious, fortunately, it took a month, and finally the spirit stone is put away, and with the last spirit stone in place, Hao Xuan, who was lying next to the waterfall, finally moved his head.

Hao Xuan clearly felt that the surrounding environment had obviously not changed, but it suddenly became more comfortable, and even the power of the blood veins in his body couldn't help but work, and the cultivation at the peak of the Mahayana trembled lightly under unconscious conditions, as if he wanted to break free from the shackles and enter that higher level.

Watching Lin Nan fall from the sky with admiration, holding a drawing in his hand, he kept looking around, taking out a large pile of wood that exuded spiritual power, and neatly arranged it next to the waterfall, Hao Xuan was almost scared to death.

In Hao Xuan's hundreds of thousands of years of memory, coupled with the inheritance memory brought by the Xuanwu bloodline, it is not that there is no spiritual wood in the Immortal Realm, even if it is an ordinary tree, growing in an area with abundant spiritual energy, it will also bring some spiritual power.

But on the wood that Lin Nan took out, the spiritual power aura emitted was more than the spiritual power in the body of the Jindan stage monk, and every piece of wood had it, what did it mean?

There is a race in the immortal world, called Phantom Wood, this race, said to be a plant, but has its own thoughts, can cultivate, said to be a spirit animal, but can not speak, can not move, after taking root, it has been growing in place, even if the strength is improved, but even the transformation can not be done.

There was once a human monk who wanted to peek at this race, but after a lot of hard work, he finally cut down a phantom tree and took the trunk with it...... Or rather, when the body left, it died in a pile of fallen leaves.

After that, the Terran and the Phantom Wood Clan had a big war, and even the Cave Void Monks participated in the battle, but the Terran monks became the nutrients of the Phantom Wood Clan and contributed their lives to the greening of the Immortal Realm.

Now seeing the spirit wood that Lin Nan took out, Hao Xuan was really shocked, was this the slaughter of the phantom wood clan?

"Lord Tianzun, this is ......"

Hao Xuan is not at ease, it is better to ask, although it doesn't matter if the Phantom Wood clan knows, anyway, they can't move, hey, it seems that there is nothing to worry about.

"This is the spirit wood I planted myself in the Endless Gate. ”

Lin Nan measured the distance, saw Hao Xuan asking, and following the direction of Hao Xuan's finger, Lin Nan explained indifferently.

Hearing Lin Nan's answer, Hao Xuan had only one thought in his heart, worthy of Lord Tianzun, even spiritual trees can be planted, Lord Tianzun's cock exploded.

With the construction of a spiritual tree, a plank road, just appeared on the waterfall, looking up, the plank road bypassed the waterfall rushing down, wrapped the waterfall in it, as if it was natural, and with the appearance of the plank road, the egg that had not moved for 500,000 years actually shook a little.

Another month passed, Lin Nan built countless facilities, wooden houses, roads, and also opened up caves on some mountains, under Lin Nan's actions, the spirit beasts in the core of the entire martial domain felt that the living conditions had changed, becoming more harmonious and more livable.

"Incubation time remaining: August 19, 523646 10 hours 3 o'clock"

When the Royal Beast Workshop was built, Lin Nan clearly saw the remaining hatching time of the immortal beast eggs through the token, no wonder there has been no movement for so many years, it will take 520,000 years.

However, Lin Nan found that each immortal stone can accelerate the incubation time of the immortal beast egg for 10,000 years, when Lin Nan held a fairy stone close to the immortal beast egg, the immortal beast egg, which was originally motionless, shook slightly, and the immortal stone in Lin Nan's hand turned into a pure white light and integrated into the immortal beast egg, and the incubation time was immediately reduced by 10,000 years.
