When Lin Yun heard this, he quickly put the body of the Tianhuo Iron Ox into the storage space.

"Now, we can start exploring this space." Lin Yun smiled.

However, before exploring, Lin Yun had to charge his wrist guards once. This thing cannot be temporarily charged during battle, so after each use, he had to replenish his energy in advance.

Immediately afterwards, Lin Yun opened his firepower and injected his wrist guards with internal strength and spiritual power.

After these two types of energy enter the wrist guard, they will be fused by the formation in the wrist guard and refined into a special energy.

It’s like smelting iron into steel, but Lin Yun injects a lot of internal energy and spiritual power, and the special energy that is finally transformed is very little.

At this time, the little green dragon was also refining the demon spirit of the Tianhuo Iron Bull in the Qingviao space.

While charging the wrist guards, Lin Yun was also thinking about the battle just now.

The Lingxiao Sword can penetrate the thick skin of the Tianhuo Iron Bull and break the heart of the monster. In addition to the wrist guards, the Lingxiao Sword's armor-piercing effect also contributes to the indelible contribution.

If it were the Red Blood Sword, even with wrist guards, it might be difficult to completely pierce the thick skin and break the heart.

The armor-piercing effect of Lingxiao Sword has no intuitive visual effect in combat, and it does not look as gorgeous as some skills, but its actual armor-piercing power is quite effective.

Especially in the face of this monster with extremely strong defense, its armor-piercing effect is the most useful!

With Lin Yun’s current strength, with the special ability of wrist guards, if you find the right opportunity and accidentally explode the power of wrist guards, you will have the opportunity to use this move to seriously injure and kill a first-level Mahayana realm.

Before, Lin Yun failed to kill the leader of Xuanguang Sect outside the stone gate because Lin Yun had just finished charging and was in poor condition. He was passively responding and was unprepared.

Moreover, before that, Lin Yun had never used the special energy of the wrist guard. That was the first time he used the wrist guard. It was for the purpose of testing the effect, not to find the opponent's weakness and kill him with one blow.

About twenty minutes later, Lin Yun once again completed the recharge of his wrist guards.

Lin Yun spent more than half an hour to restore his state to fullness before he began to explore the space.

Lin Yun moved forward while releasing his spiritual consciousness, and there was another danger in the dike.

Not long after, Lin Yun came to the center of the space, where there were continuous buildings.

However, due to disrepair, these buildings have long collapsed.

"These buildings are probably tens of thousands of years." Lin Yun couldn't help but sigh at the collapsed and dilapidated buildings.

These buildings were once very majestic.

The power of time is terrifying.

However, there is a huge stone tablet standing in front of these buildings. Although it looks very old, it is still intact.

Lin Yun quickly came to the stone tablet.

Standing for tens of thousands of years and intact, Lin Yun believes that this stone tablet should have its own special place.

Lin Yun tried to touch the stone tablet with his hand.

Rumble!

With a trembling trembling, the gate of the stone tablet was actually separated.

The road leading to the underground appeared in front of Lin Yun.

Where this passage leads is of course an unknown number. There is no way to know whether it is a treasure or a life-threatening trap.

Lin Yun tried to release his spiritual consciousness and search, but found that his spiritual consciousness could not be covered.

Enter or not?

After a moment of thinking, Lin Yun walked into the passage.

However, Lin Yun was careful every step he took, and the danger of the dike came. If the situation was wrong, he was ready to escape at any time!

After Lin Yun walked along the passage for a few minutes, a small palace appeared in front of Lin Yun.

Will there be a treasure? Lin Yun swept the small hall with expectations.

There was nothing in the small hall, only a stone tablet was erected.

"It's another stone tablet, there's nothing else."

Lin Yun said as he came to the stone tablet.

Lin Yun was still wondering whether there would be a lot of treasures here, but things went against their wishes.

Lin Yun came to the stone tablet and tried to put his hand on the stone tablet again.

Buzz!

As soon as Lin Yun's hand touched the stone tablet, a large stream of information suddenly poured into Lin Yun's brain.

Holy Light Nirvana Technique!

Suck the energy of heaven and earth and turn it into your own use.

Lin Yun discovered that what came to his mind turned out to be a Holy Spirit-level secret book called the Holy Light Nirvana!

A huge amount of information is constantly input into Lin Yun’s brain.

It took only two hours for the information to be transmitted.

"It's actually a Holy Spirit-level secret book. This trip is so worth it!" Lin Yun was very happy.

Moreover, Lin Yun looked at it and found that the effect was quite amazing!

As soon as such a Holy Spirit-level secret book was obtained, Lin Yun couldn't wait to start comprehend this Holy Light Extinction Art.

Three days later.

Lin Yun successfully mastered the first level of the Holy Light Nirvana Art, Ten Miles Nirvana.

Once used, you can absorb the energy of heaven and earth within a radius of ten miles, so that your strength can be improved in a short period of time!

“It’s time to go out.”

After confirming that there was nothing else around, Lin Yun turned around and left.

The owner of this space only uses this secret, probably because he wants someone to pass on this secret.

Although I haven't found anything else, it's already worth it just because of this.

After leaving this small hall, Lin Yun returned outside.

As soon as Lin Yun walked out of the corridor, he found two figures standing in front of the stone tablet passage.

Lin Yun looked closely and saw that one of them was the leader of Xuanguang Sect.

As for the other person, his hair was gray and he looked quite old, Lin Yun didn't know him.

"Boy, we're meeting again." The leader of Xuanguang Sect smiled.

"Master of Xuanguang Sect, you were letting you go last time, so you really don't have a memory." Lin Yun's eyes were cold.

The last time Lin Yun played with the leader of the Xuanguang Sect was outside the cave. Lin Yun was in poor condition at that time and was the first time he used the "wrist guard" and only aimed at the experimental results.

It's different now.

This time Lin Yun was in full condition and also figured out the function of wrist guards.

Moreover, Lin Yun just learned the technique of the Holy Light Nirvana!

If one-on-one, Lin Yun will make him unlucky.

"Haha, the treasures in this space and the treasures on you really make this sect leader moved. This time, the sect leader brought another Mahayana realm. No matter how many methods you do, today it will be a dead end!" The sect leader of Xuanguang Sect laughed.

After the words were finished, the leader of Xuanguang Sect immediately released his first-level Mahayana realm aura.

The gray-haired old man next to the leader of Xuanguang Sect also instantly released a powerful realm aura, which was actually the first-level Mahayana realm!

"Is there another Mahayana realm? No wonder I dare to come back." Lin Yun's eyes narrowed.

Lin Yun is still quite sure to deal with a first-level Mahayana realm.

But when dealing with two first-level Mahayana realms at the same time, Lin Yun knew that he was definitely not an opponent!

If you can't beat it head-on, there is only one way to escape!
