The huge cave world suddenly became dead.
Old Man Tianfang and the Ancient Beast Dazai both perished, leaving him the only living creature left in this cave world.
Lin Mu's gaze was instantly fixed in the depths of the cave.
An old gray stone platform with a mysterious gray mist lying on it.
Lin Mu's eyes touched this mysterious gray mist, and Lin Mu felt an inexplicable feeling of intense palpitations in his heart.
He tried to see with his heavenly eyes, but what he saw was still a fog.
This shook him to his core.
He has always known that the Sky Eye has limitations, but that limitation only lies in the space formation. In other aspects, the Sky Eye has never been hindered by any obstacles.
However, there is clearly no spatial fluctuation in this mist, so it is naturally impossible for a large spatial formation to exist.
This is the first time that the Sky Eye has been unable to see through something without encountering a large space formation.
"Source Marrow."
Golden Dragon Vine's shocking voice suddenly sounded at this moment.
"Original marrow?"
Lin Mu was puzzled.
Golden Dragon Vine showed rare excitement: "The source marrow is similar to human bone marrow. You can think of it as the marrow of most worlds."
Hearing this, Lin Mu was shocked: "Is there such a thing in this world?"
"Of course, human beings belong to all living beings in the world and are all derived from Tarsus. Humans can all have bone marrow. It is not surprising that Tarsus has source marrow."
Golden Dragon Vine was very excited: "No wonder Dazai Ancient Beast and Tianfang Old Man are willing to risk their lives for this thing. This is really a great opportunity. If they get this thing, with their cultivation level, I am afraid they will have a chance to make breakthroughs, even if they are not comparable." Even the most holy can also become a being at the level of Three Emperors."
Lin Mu even looked solemn.
Becoming a Three-Emperor-level existence?
He knew that Golden Dragon Vine would never exaggerate, which showed that the value of this source marrow was more terrifying than he thought.
"How to use this thing?"
For a moment, Lin Mu really didn't dare to touch the source marrow easily.
"If you can transplant this marrow into your body and use it to slowly transform your bone marrow, and then your bones and blood, then your physical body will be strengthened to an unimaginable level."
Jin Jiao Teng said: "If you really succeed, you may have a glimmer of hope in the future and be able to compete with the Holy Saint."
As a creature that once followed Heiyun Sanren and experienced Heiyun Sanren being killed by the Holy One, there is probably no one in the world who understands the horror of the Holy One better than it.
Even if they are the Three Emperors, the Holy Saint cannot touch them just because they are unwilling to pay the price. After all, the Three Emperors are not only powerful, but also highly respected. If they touch them, even the Holy Saint will be injured.
But if one day, the three emperors violate the core interests of the Holy Saint, then the three emperors will also be unable to bear it.
At this time, Jin Jiao Teng changed the topic again: "But the strength of your physical body is still too low. If Luo goes to refine this source marrow, your body will explode if you keep it, and your soul will be blown away."
Lin Mu's tone was solemn: "Is there a solution?"
"The solution is to find a medium."
The golden dragon vine muttered: "There are several treasures in your body, including the hidden night mirror, the Western Emperor's jade plate, the golden dragon cloud, the golden dragon gourd, the immortal-killing flying knife, and me."
"These treasures themselves are refined by you. You use them to fuse with the source marrow first, and then further merge with your body, which can act as a buffer."
"I want to maintain the founding world, so I can't help with this. The Hidden Night Mirror seals the eternal night, which is not suitable. The role of the Western Emperor's jade plate, golden dragon clouds and golden dragon gourds is also not here. This is the most suitable one, undoubtedly. It’s an immortal-killing flying knife.”
Lin Mu's eyes looked strange: "Immortal-killing flying knife?"
"I can see that no matter how powerful the other treasures are, they are still not as important as the Immortal-Slaying Flying Knife in your mind. To you, it is a bit like a natal magic weapon."
Golden Dragon Vine had obviously seen through many of its essences, and said slowly: "So, it is your best choice. I suggest you use it to fuse the source marrow, and then turn it into your bones."
"good."
Lin Mu nodded without much hesitation.
Just as Jin Jiaoteng said, although there are many magic weapons in his body, none of them hold the same status in his heart as the immortal-killing flying knife.
The other magic weapons were obtained after he became stronger, but the Immortal-Slaying Flying Knife has been with him since he was a loser until now.
Then, he took out the Immortal-Slaying Flying Knife and asked, "How do I fuse this source marrow with the Immortal-Slaying Flying Knife?"
The source marrow was a mysterious substance beyond his control, and he didn't know how to treat it.
"Just treat it as an ordinary substance and follow the method of refining it. Leave other issues to me."
After Jin Jiaoteng finished speaking, he rarely released a particularly solemn mood swing.
Although it sounds easy, in fact I dare not be careless in any way.
After all, this is the source marrow. If it can be conquered successfully, it will be of great help to it and Lin Mu's future. On the contrary, if it fails, this creation will be lost.
Lin Mu did not hesitate. After Jin Jiao Teng said this, he made a prompt decision and controlled the immortal-killing flying knife to approach the source marrow. At the same time, his soul power extended over to fuse the source marrow and the immortal-killing flying knife.
What happened next was just as he expected, as soon as the Immortal-Destroying Flying Knife and his soul power approached the source marrow, a terrifying coercion was released from the Source Marrow, preventing him and the Immortal-Destroying Flying Knife from approaching.
But at this moment, the void buzzed and vibrated, and even more terrifying pressure fluctuations rose into the sky, causing the entire cave world to shake violently.
This fluctuation clearly came from Lin Mu's body.
To be precise, it comes from the golden dragon vine.
To maintain the operation of the founding world, the Golden Dragon Vine cannot unleash its power against the enemy, but it is still possible to use coercion to suppress other spiritual beings.
This source marrow is a spiritual object, and its value is no less than that of most objects.
But after all, it has not been developed, and its potential can be said to be completely hidden.
The golden dragon vine is different. It was discovered as early as the wilderness period and is very powerful.
If the source marrow is compared to a baby among many things, then the golden dragon vine is an adult. No matter how great the source marrow's potential is, before it develops, it can only be obedient to the golden dragon vine.
Sure enough, under the pressure of the golden dragon vine, the pressure of the source marrow quickly shrank, trembling, and could only let Lin Mu do what he did.
time flies.
One day, two days, three days...
Five days later, the gray fog completely disappeared.
On the other hand, the color of the Immortal Killing Flying Knife has changed, it is no longer golden, but dark golden.
And the surface is no longer smooth and has become a matte state, which makes people feel more vicissitudes of life.
"Finally successful."
Lin Mu's eyes flashed, and then he became a little confused, "Why do I feel that the power of the Immortal-Slaying Flying Knife has not increased much?"
At this moment, the power of the immortal-killing flying knife has indeed increased.
Before this, the lethality of the Immortal-Slaying Flying Knife was probably comparable to a low-level top-grade treasure, but now it is equivalent to a high-grade top-grade treasure.
This kind of power was already quite impressive, but it was far different from Lin Mu's expectations.
You know, Jin Jiao Teng had previously described this source marrow as "unique in the sky and unparalleled in the earth", which made Lin Mu feel that the power of this source marrow was at least as powerful as the emperor's treasure, and even surpassed the emperor's treasure. But now the situation is obviously far different.
