In the blink of an eye, it was dawn.

For a whole night, Lin Hong didn't close his eyes.

He was so anxious that he couldn't sleep, so he had to devote all his energy to studying the red spirit crystal.

This red spirit crystal is no more than the size of a knuckle, the color is as bright as blood, through the light, you can see that there is a trace of flame-like existence in this crystal, although there is only a trace of this thing, but it is constantly beating in the crystal, as if the vitality is extremely vigorous.

This trace of flame-like things made Lin Hong think of Tong Jun!

Lin Hong heard that on the day of the challenge, Tong Jun's heart was brutally gouged out by Bei Liang after his death, but who knew that the heart suddenly exploded, and a red light rose into the sky, causing Bei Liang to almost go crazy.

That red mang, and this red spirit crystal, should have some kind of connection.

Or, that red glow is the crystal of this red spirit!

"Na Bel Liang and Tong Jun are both extremely mysterious, the two of them are incompatible, even if Na Bel Liang gets this red spirit crystal, he will definitely not be able to use it because of the mismatch of the surname...... The explosive fist used by Tong Jun is not even recorded in the Qingshan Sect...... However, Zao Wou-Ki can use explosive punches, and his realm seems to be quite low......"

A series of questions appeared in Lin Hong's mind, and these questions were not something he could figure out. Although he couldn't figure it out, he knew that the red spirit crystal must not stay on him for a long time.

The last time it was in the valley, if this red spirit crystal emitted on its own, then the next time it emitted a red ray, it would be its own death!

If that red light is emitted by some kind of force, then there is no guarantee that that power will appear again!

Either way, as long as this Red Spirit Crystal can't be disposed of properly, what awaits you is an ominous fate!

"You can't throw it away, you can only use it, but, how should you use this thing?"

Lin Hong held the Red Spirit Crystal in his hand, his eyes locked on the red flame that was constantly beating in it, slowly calmed his mind, and injected a trace of divine thought into it.

It's just that as soon as his divine mind touched the red crystal, it was bounced away, Lin Hong shook his head slightly, smiled bitterly, and threw the red spirit crystal into his sleeve pocket.

"Trouble ......"

Lin Hong groaned slightly, looked out the window, and seeing that the sky was already bright, he got up and walked in the direction of the battle hall.

Lin Hong hung a battle-free card on the door, and in the room, Lin Hong's divine thoughts repeatedly entered and exited the golden rune space, constantly using explosive punches to enhance his perception.

In the golden rune space, the entity transformed by the divine thought has the peak of the seventh layer of Xuan Qi, even if it is exhausted, the body in reality will not be affected, just inject a trace of divine thought into the golden rune again, and you can get a body full of Xuan Qi again.

Therefore, it is most suitable to use this golden rune space to cultivate mystical techniques.

In the blink of an eye, seven days passed.

In the golden rune space, Lin Hong's figure formed by a trace of divine thought was as stable as a stake, and his right hand smashed forward like a cannonball, and a red fist instantly condensed out in front of his fist, and the air suddenly produced a slight shock, under this shock, I saw Lin Hong's right hand tremble slightly, and a red fist strength rose from his fist again, like two layers of waves, moving quickly in the air, but the two layers of fist strength never coincided together.

Two explosions, this time, it didn't turn into invisibility as soon as Lin Hong showed it to Zao Wou-ki, but rushed forward for a full time before slowly dissipating.

"I have basically mastered the double explosive intent of this explosive punch. ”

Lin Hong's eyes stared ahead, in the past seven days, he has nearly ten points of understanding of the strength of these two layers of explosive punches, according to his perception, the heavy explosive intent of the explosive fist is similar to the tiger fist, he has already had a perception of the tiger fist, he can already perform it perfectly, however, the explosive fist of the first explosive intent is completely superior to the tiger fist in terms of power!

The power is twice as great as the yang energy of the yin and yang energy of the three-grade Xuan Technique!

If you can reach the triple level of explosive intent, the power should be able to completely surpass the yin and yang energy of the three grades, and if it reaches the quadruple power like Tong Jun, I am afraid it will reach a higher level.

And how many layers of explosive intent can be superimposed by this explosive punch, Lin Hong is still unclear, if it can reach nine or more, it is estimated that if this punch goes down, even if it can't open the mountain, it can blast out a cave in the mountain.

"No wonder Zao Wou-Ki said that this explosive fist refining to the greatest level is comparable to the five-grade mystical technique...... It's just that, with my current perception, it is difficult to perfectly use the double explosive intent, let alone triple or quadruple, and the higher level is almost impossible to achieve......" Lin Hong withdrew his divine thoughts from the red rune space, took a deep breath, and said in a low voice: "What is the identity of this Tong Jun, how can he master such a powerful mystical technique, that Bei Liang is even more terrifying, and he easily killed Chen Cheng......"

"The Red Spirit Crystal, I'm afraid it will be a scourge to stay on my body......"

Lin Hong took out the Red Spirit Crystal from his sleeve pocket, glanced at it, and shook his head slightly, he could feel that this Red Spirit Crystal contained a mysterious energy in it, but he didn't know what it was for.

Lin Hong had thought about finding a hidden place to throw away this red spirit crystal many times, but the mysterious energy contained in it made him never be ruthless. After sitting upright in the battle hall and studying for a while, Lin Hong still had no clue about this red spirit crystal, and couldn't help but smile bitterly:

"I really shouldn't have taken this red spirit crystal at that time, and it just increased my troubles by keeping it on my body. ”

Shaking his head, Lin Hong got up from the ground, opened the door, and walked towards his residence.

When he returned to the room, Lin Hong saw a letter and a token on the floor under the door, which said that if he came back, let him take the token and go to the Hall of Famous Instruments to find Tang Wang.

"Mingqitang?"

Lin Hong had heard of this name before. There are a variety of weapons in the Hall of Famous Weapons, and there are some treasures, but it is extremely difficult to exchange these treasures, and few people do it.

"I don't know what the master asked me to go to the Hall of Famous Instruments. ”

Lin Hong thought for a moment, then closed the door and walked in the direction of the Hall of Famous Instruments.

......

"Inner Gate Xuanqi Stage disciple, this is not the place you should come, leave quickly. ”

Outside the Hall of Famous Instruments, there was an old man in a black robe who was in charge of guarding, and when he saw Lin Hong coming, he issued a warning from a distance.

Lin Hong frowned slightly, touched his sleeve pocket, handed over the token that Tang Wang handed over to him, and said, "It was Tang Protector who called me." ”

The black-robed man took the token, looked at it carefully, and turned sideways to give way: "It is indeed Tang Protector's edict, he has been waiting for you inside for two days, let's go in quickly." ”

Lin Hong nodded, walked through the road left by the old man, came to the Hall of Famous Instruments, pushed open the hidden door, and slowly walked in.

"That's a lot of weapons!"

As soon as Fang entered this hall of weapons, Lin Hong was attracted by the weapons hanging all over the room, these weapons were either simple in shape or flickering in cold light, and each handle seemed to be extraordinary.

"You're here. Tang Wang's figure slowly walked over from a distance.

"Let the master wait for a long time. Lin Hong suddenly clenched his fists.
