Although the mortal immortal Zun doesn't know what Lin Feng's method is for the time being, she knows that Lin Feng is not an aimless person. Since she says there is still a way to try, there should be a way. What is the specific method? Just wait a moment and you can know.

At this time, Lin Feng summoned the mysterious iron box. After the mysterious iron box came out, it was suspended above Lin Feng and the mortal immortal. The rolling blood itself was no longer afraid of the mysterious iron sword, but when the mysterious iron box flew out, all the blood was fixed in the void.

It's not really fixed in the void. It's a little similar to that a person sees some terrible existence and feels scared silly. Those blood are similar situations, as if he was scared silly by the mysterious iron box.

"It's impossible, it's absolutely impossible. How can this box still be in the world?" the existence in the blood pool shouted unbelievably. The mysterious iron sword has brought him a great shock. Now after seeing the mysterious iron box, his shock is even stronger.

However, these two shocks are different.

When it sees the mysterious iron sword, it wants to take away the mysterious iron sword, because in its view, the mysterious iron sword is something that can be controlled.

However, when he saw the mysterious iron box, he had only one thought in his heart.

That's fear.

It doesn't know why the mysterious iron box still exists in the world. It's reasonable that the box has been destroyed. However, the mysterious iron box appears in front of us, which is an irrefutable fact. Even if you don't want to admit that the mysterious iron box has not been destroyed, you should admit it.

At this time, the mysterious iron box made a clicking sound. Lin Feng just summoned the mysterious iron box and did nothing else. Even though Lin Feng had controlled the mysterious iron box for many years, he still lacked understanding of the mysterious iron box and was full of fear of the mysterious iron box.

Mainly because the mysterious iron box is too scary and hides some extremely terrible secrets.

And it's extremely dangerous.

This time, the mysterious iron box took the initiative to open, obviously because of the blood pool. Did the blood in the blood pool arouse the interest of the mysterious iron box?

The mysterious iron box does devour some special blood.

The blood pool is so strange. It's not too surprising that the blood in the blood pool is stared at by the mysterious iron box.

There is no time for the blood in the blood pool to target Lin Feng and the immortal of the red world. All the blood is rolling, trying to tear the void and escape here.

However, the mysterious iron box didn't give these blood any chance at all. The mysterious iron box shook the void. When this shock occurred, the mysterious iron box seemed to form an extremely special connection with the surrounding void. If you had to add an adjective to this extremely special connection, it was "resonance".

After forming this resonance, the blood in the blood pool can't break through the void and escape here.

The mysterious iron box finally opened a gap.

When the mysterious iron box opened the gap, Lin Feng pulled the red dust immortal Zun back quickly and opened a safe distance from the mysterious iron box, because Lin Feng knew very well that every time the mysterious iron box was opened, if it was too close to the mysterious iron box, it would be attacked by the mysterious iron box.

The attack of the mysterious iron box is too terrible. Lin Feng doesn't want to be injured by the mysterious iron box again.

The powerful phagocytic power surged out. The blood in the blood pool was shrouded by the phagocytic power released by the mysterious iron box. The blood in the blood pool was constantly struggling, but no matter how struggling, there was no way to resist the phagocytosis of the mysterious iron box. The blood in the blood pool kept flying towards the mysterious iron box.

The mortal immortal frowned and said, "I didn't expect that this thing has become so terrible!".

Before, the mortal immortal Zun knew that Lin Feng mastered the mysterious iron box. She had a certain understanding of the mysterious iron box and knew the horror of the mysterious iron box. However, she never thought that the mysterious iron box had been terrible to the present extent, which made people feel frightened.

She is also very clear that there seems to be an interdependent relationship between Lin Feng and the mysterious iron box. In the future, the two sides may fight to the death because of the problem of control. Now, red dust immortal Zun will naturally worry about Lin Feng when he sees that the mysterious iron box is so strange and terrible.

Lin Feng said solemnly, "the mysterious iron box is getting stronger all the time, and it will become stronger and stronger as time goes by!".

The mortal immortal Zun said, "maybe we can find a way once and for all!".

The words of the mortal immortal Zun are not complete, but Lin Feng knows what the words of the mortal immortal Zun mean. Although the mysterious iron box will play a great role in many times, the mysterious iron box is also a great threat to Lin Feng. The mortal immortal Zun probably wants to help Lin Feng control the mysterious iron box, rather than being controlled by the mysterious iron box one day.

Lin Feng naturally looks forward to being able to control the mysterious iron box. However, the more he understands the mysterious iron box, the more he knows how terrible the mysterious iron box is.

Outsiders can't meddle in the affairs between him and the mysterious iron box. Once they meddle in, there may be some extremely bad situations.

Lin Feng naturally knows that the mortal immortal respect is for his own good, but Lin Feng can't let the mortal immortal respect take risks for him.

Lin Feng said, "don't worry, I'm fine. The mysterious iron box doesn't pose a threat to me! You don't have to worry about this!".

Seeing Lin Feng's resolute attitude, the mortal immortal Zun nodded without saying anything else.

At this time, most of the blood in the blood pool had been swallowed by the mysterious iron box.

The voice of the spirit came from the rest of the blood. The Spirit said to Lin Feng, "hurry up and stop the box from swallowing me. Although you are in charge of the box now, you can't control the box. If you stop the box from swallowing me, I'll tell you all about the origin, weaknesses and so on!".

After hearing the words of Xuechi Xueling, Lin Feng couldn't help feeling a little excited, because what Xuechi Xueling said was exactly what Lin Feng wanted to know, but there was no channel to know.

However, before Lin Feng made a reply, the mysterious iron box increased the phagocytosis, and a large amount of blood was swallowed by the mysterious iron box. Lin Feng had no way to stop the mysterious iron box from swallowing the blood in the blood pool. Finally, all the blood in the blood pool was swallowed by the mysterious iron box. After swallowing the blood in the blood pool, the mysterious iron box took the initiative to close, And took the initiative to return to Lin Feng's Dantian.

then.

Deep dormancy.
