The reason why Lin Fan rented this secret room was originally to verify whether the golden ocean in his sea of consciousness was condensed by soul fluid, and now it has been proved that the golden ocean is condensed by soul liquid.

Although he couldn't absorb the golden soul liquid in the golden ocean, the goal had been achieved, and even the pale golden soul liquid refined by Tianjing had been absorbed by Lin Fan, so there was no need to continue to stay in the secret room.

Immediately, Lin Fan left the secret room.

After leaving the secret room, Lin Fan returned to the soul hall and refined the remaining heavenly crystals in his hand into soul liquid, although those heavenly crystals were all refined into soul liquid, they would not make their Yuan Shen much stronger, but no matter how small the mosquito meat was, it was still meat!

After refining all the heavenly crystals into pale golden soul liquid, Lin Fan did not take it, but put the soul liquid away, and then left the soul hall and returned to the inn.

After resting in the inn for a day, Lin Fan prepared to leave Blackwater City and continue to hunt tower beasts outside the city, and this time Lin Fan planned to hunt tower beasts while looking for marauders who were often active outside the city.

Lin Fan, who had an experience of eating black once, knew that the Heavenly Crystals on these marauders were the most, and snatching the Heavenly Crystals on these marauders was the fastest way to get them!

"Brother Lin, what a coincidence!" A familiar voice sounded behind Lin Fan who was walking towards the city gate, and Lin Fan looked back and saw that it was night and day zero that had not been seen for many days.

"Brother Night, it's you! It's been a long time!" Lin Fan smiled slightly.

"Brother Lin, are you planning to hunt tower beasts outside the city? Me too, why don't you join you? I know a secret place, where killing a few tower beasts will basically have a Sky Crystal. Night Zero walked in front of Lin Fan.

"If there is such a treasure, then I shouldn't miss it. Brother Night, thank you!" Lin Fan thanked.

Leaving Blackwater City, Ye Lingtian was brought in front, and Lin Fan followed behind Ye Lingtian.

Halfway through the road. Lin Fan suddenly felt as if he had walked this road, and with a flash of inspiration, Lin Fan remembered this road, when he had just entered the space of the first layer of the Heavenly Tower of the Thirty-Three Heavenly Towers, he accidentally encountered Ye Lingtian, and Ye Lingtian took this road to bring himself to Blackwater City.

"Brother Night, this road seems to be the same road you took me to Blackwater City last time, could it be that the place you said is on this road?"

"Yes, that place is indeed on this road, but farther away, farther than the place where we met!"

A few days later, Night Zero took Lin Fan to the entrance of a cave.

"Brother Lin. This is the good place I told you about!" Ye Zerotian pointed to the entrance of the cave in front of him, "I discovered this cave by accident, the cave is crisscrossed by passages, and each passage leads to a vast space where several tower beasts live. Most of these tower beasts have Celestial Crystals hidden in their bodies. It's just that these tower beasts are all social types, and the strength of most of them has reached the middle stage of Xuan Immortal. If you want to hunt, it's more troublesome!"

"The tower beast of the social type is better!" Lin Fan smiled faintly.

Forthwith. Lin Fan walked into the cave.

In the cave, as Ye Zerotian said, the passages are criss-crossed, and each of these passages is very wide, about 100 meters wide and high!

Walking along a passage to the end, what appeared in Lin Fan's eyes was a huge underground space.

I don't know what the reason is, but the underground space that should be pitch black is as bright as the outside world. But Lin Fan didn't find anything that shone brightly.

"Doesn't it feel amazing, it's obviously an underground space, but it's as bright as the outside world?"

"Yes, do you know Brother Night?" Lin Fan asked.

"I don't know!" Night Zero shook his head.

“”

Boom!

A loud roar came from afar, and the ground trembled. The huge boulder towering over the ground shook as if it were about to collapse at any moment!

Lin Fan looked around, and saw a group of bison-like tower beasts running dozens of kilometers in front of him, kicking up bursts of dust, the number of which was more than tens of thousands, the scene was mighty and magnificent!

"It's really a group dwelling class, this number is tsk!" Lin Fan looked at the group of bison tower beasts running past from the front, and sighed.

"It's a buffalomon, a kind of social tower beast in the underground space. Almost every time it appears, it is a large group, and the number is not less than 10,000! Although the strength of these green bull beasts is only in the early stage of Xuan Immortal, there are too many of them, if they accidentally fall into the bison herd, then the injury is certain, and if they don't do it, they will be killed!"

"The most important way to deal with a group tower beast is a formation!Brother Night, are you familiar with this underground space?Is there a suitable place to arrange a formation?" Lin Fan smiled slightly, and quickly thought of a way to deal with a group tower beast.

"Brother Lin, do you know how to set up a formation?, are you a formation master?" Ye Lingtian said in surprise.

"What's the matter, Brother Night, haven't you practiced the formation?" Lin Fan looked at Ye Lingtian suspiciously.

Ye Lingtian shook his head: "No, because cultivating the formation requires a lot of energy, and it will affect cultivation, so except for some talented people, few people will be distracted to practice the formation." Although I didn't practice formations, I still knew some basic knowledge of formations. ”

"I've only been to this underground space once, and I'm not very familiar with the environment here, but I know a place that is very suitable for arranging formations!"

After speaking, Night Zero Sky rose into the sky.

Soon, Lin Fan and Ye Lingtian came to the place he said was suitable for arranging the formation.

It was a circular valley with a diameter of tens of kilometers, surrounded by peaks hundreds of meters high on all sides, except for an entrance.

Lin Fan fell in love with this place at a glance, if a killing array was arranged here, it would definitely allow those tower beasts to enter and exit, and kill them without leaving a piece of armor!

"Brother Night, I'll arrange the formation here, you go around and see if there is a tower beast group, and when I finish arranging the formation, I will give you information, and you can lead the tower beast group here!

"No problem!" Night Zero slapped his chest, and left the valley to find the tower beasts.

After leaving at night and day, Lin Fan began to arrange the formation.

First, he took out a large number of materials for arranging the formation from the Wanbao Ring, and then refined these materials into a dark golden liquid, and then used his divine thoughts to control these dark golden liquids to outline mysterious formations in the void!

About an hour later, a huge formation was formed under Lin Fan's hands.

The moment the formation was formed, the array patterns suddenly lit up, and at the same time, a powerful Liliang fluctuation erupted from the formation, and then the formation diagram slowly sank into the ground of the valley.

However, this is how the formation has not really been formed, and there is still a lack of treasures to suppress the formation eye!

I saw Lin Fan's hand shake, and twelve high-grade immortal weapon flying swords appeared in front of Lin Fan, and fierce sword qi shot out from these flying swords, and a ripple appeared in the space, as if it would be cut by sword qi at any time!

Lin Fan's mind moved, and the twelve high-grade immortal weapon flying swords turned into twelve white lights and rushed into the twelve formations of the formation, and suddenly a dazzling pillar of light in the valley rose into the sky, clearly visible within a radius of hundreds of kilometers!

Ye Lingtian, who was hiding near a group of tower beasts, also saw this pillar of light, and secretly said in his heart: It seems that Brother Lin's formation arrangement has been completed!

Sure enough, it didn't take long for Ye Lingtian to feel a fluctuation from the communication jade talisman in his hand, the divine thought was connected to the communication jade talisman, and Lin Fan's voice immediately sounded in Ye Lingtian's mind: "Brother Night, the formation has been arranged, you can lead some tower beasts over!"

Disconnecting the communication jade talisman, a smile flashed on Ye Lingtian's face, and then his figure flashed in front of the group of tower beasts in front of him, his whole body was agitated, his hands pinched the immortal technique, and countless fire qi gathered around Ye Lingtian, turning into a fire snake more than ten zhang long.

The fire snake snaked and swam, rushing into the tower beast group, and then exploded, waves of huge energy streams impacting the tower beast group, these energy flows did not cause much damage to those tower beasts, but they successfully caused their anger, and they rushed towards the night zero sky.

Night Zero Haha smiled, his figure flashed rapidly, and he dragged the group of tower beasts towards the direction of the valley.

Not long after, the mighty tower beast herd was led into the valley by Night Zero.

"Brother Lin, it's up to you!" Ye Lingtian's figure flashed and appeared next to Lin Fan.

Lin Fan, who had been waiting for a long time, nodded slightly, his hands pinched, and the valley that seemed to have no vision suddenly shone brightly, and a huge array appeared, and a barrier appeared at the edge of the formation to trap all the tower beasts in the formation!

Subsequently, a terrifying sword qi appeared out of thin air in the formation, and began to harvest the life of the tower beast in the formation, and every time the sword qi crossed it, a tower beast fell to the ground and died!

"Brother Lin, what kind of formation are you, it's so powerful!" Night Zero watched as the tower beasts in the formation fell in pieces, and the blood that flowed out dyed the entire valley red!

"Twelve days!" Lin Fan said lightly.

Roar!

Seeing that their companions were killed one by one and their lives were threatened, the tower beasts in the Twelve Heavens Jianzhen suddenly became crazy, their eyes were red, and waves of powerful liliang burst out, frantically attacking the Twelve Heavens jianzhen!

However, it was already too late!

After the twelve days of jianzhen activation, the power exerted will become more and more powerful, and the speed of the death of the tower beast in the formation will become faster and faster!

Half an hour later, all the tower beasts in Tianjianzhen died!

"Brother Night, let's go collect the Tianjing!" Lin Fan said with a smile.

"Haha! Brother Lin, it's cool to have you as a formation master! Killing tower beasts are all in groups, and I have never tried such a cool thing!"

Lin Fan and Ye Lingtian flew down into the valley and began to collect the heavenly crystals. (To be continued......)
