The thunder was loud, and Lin Feng had already started a new refining process.

After the twelve thunder and lightning training, Lin Feng's physical cultivation reached an unprecedented level, and after completely completing the bone forging and muscle casting, the thirteenth thunder and lightning training came as scheduled.

"Boss, this is the most difficult level to pass, if you pass this refinement, your physical strength will reach the realm close to that of a god. ”

Yu Ling's tone was very solemn, it stands to reason that Lin Feng's progress is obvious, he should be happy, obviously the difficulty of the last thunderbolt training is very huge.

Lin Feng asked, "Isn't this thunderbolt training difficult?"

"It's not so difficult, boss, so far only one person has passed the trial of the thirteenth thunderbolt, and that person is the god Asura, and all those who want to strengthen their flesh through the thunder array have been split into pieces by the thirteenth thunderbolt. ”

Yu Ling said seriously.

Lin Feng's brows furrowed, and he asked, "Why has the difficulty of the last thunderbolt refinement become so great?"

Yu Ling explained: "Boss, the last trial is called marrow washing, which is to wash all the essence and bone marrow of your body, but this kind of pain is not something that anyone can bear, not to mention that the vast majority of people's physique is just a mortal body, and the essence after purification, not only can it play a role, but it will increase the burden on the body, because it can't withstand the pressure of the essence and explode to death." ”

Lin Feng nodded and said, "It seems that this last thunderbolt training is indeed very risky, so do you think I can survive it?"

Yu Ling thought for a while and said, "Boss, you are not an ordinary person, otherwise you would not be able to cultivate the Seven Colors of Vitality, so I believe that you have no problem, but can you really endure that kind of huge pain?"

Lin Feng smiled faintly and said: "Don't worry, my profession is a doctor, and I know very well what to do to alleviate the pain, but I'm more worried about Qian'er, Little Phoenix and Little Shenlong now, I don't know if they can withstand the test of this last washing thunder and lightning, and Vladimir, he is not from Huaguo, I am afraid that he will not be able to adapt to this kind of refining method." ”

Yu Ling said: "Boss, Hu Qian'er, they don't need to worry, their roots and bones are different from humans, and the flesh training has little effect on them, so the pain they have to bear will be much smaller, as for the blood duke, his body is not the same as that of humans, it can be said that it is a more advanced existence, so it is not too much of a problem to survive the past, now you still have to think about how to survive the last training thunderbolt." ”

Lin Feng thought for a moment and said, "It's easy, you can start now." ”

Before Jade Ling could speak, Lin Feng had already begun to take steps and walked in the direction of the last refining thunderbolt.

At the same time, Lin Feng had already made a lightning move, using his vitality to control the acupoint and completely seal his Ren vein.

Once the Ren pulse is closed, the person's perception will decline, and even the phenomenon of loss of consciousness will occur, which is undoubtedly the best way to alleviate the pain.

Before coming in, Yu Ling had said that once he embarked on the path of refinement, he would not be able to go out until the refinement was completed, so Lin Feng decisively chose to accept the refinement as soon as possible.

After taking three steps, the final refreshment lightning bolt was triggered.

Purple thunder and lightning instantly surrounded Lin Feng's body, and his handsome face was even more angular under the reflection of thunder and lightning.

Lin Feng's gaze flickered, and he had already felt the tremendous power of the last refining thunderbolt.

The so-called training thunder and lightning is to completely destroy the structure of the human body first, and then reorganize it with huge energy, which sounds a bit too simple and crude, which is why so many people accept the training, but few people can survive it.

After all, not everyone can bear the pain of being crushed.

Although Lin Feng was mentally prepared, when the last refining thunderbolt fell, shattering all his bones, the intense pain was still transmitted to the center of his brain.

Currents flowed along the shattered bones, completely vaporizing the bone marrow in them, and the pain that Lin Feng had to endure during this period was beyond the imagination of ordinary people.

When a person's pain was too great, fainting was the most common protective measure, but Lin Feng only felt more awake, because the last thunderbolt had already gathered in his central nervous system, and the strong stimulation made him unable to faint.

Lin Feng's whole body was soaked with cold sweat, this was definitely the most painful one he had ever felt.

Due to the shattering of bones, the whole body lost strength, and I couldn't use the strength of my muscles to offset some of the pain, so I could only grit my teeth and persevere.

"Boss, if you can't hold on, take a Dragon Tiger Pill, which will make you more comfortable. ”

Yu Ling was also distressed, he got along very well with the boss these days, so he also felt very sad when he saw Lin Feng in such pain.

Suddenly I thought that there was also the Dragon and Tiger Pill in the Canghai Storage Ring, which was a Taoist holy medicine, and it might be helpful to Lin Feng, who was in great pain.

Lin Feng clenched his teeth and said, "No need, it's not as serious as the legend, I can still bear it." ”

"Boss, hold on a little longer, and soon you will be able to generate new bone marrow by refining the thunder and lightning, and then you will be able to repair your body. ”

Through the internal vision, Yu Ling could clearly see that the bone marrow of Lin Feng's whole body had disappeared, and a new bone marrow was slowly appearing.

The newly formed bone marrow is completely different from the original, purple in color, and has a hint of divine properties, and as the new bone marrow is generated, the broken bones begin to heal.

At this time, Lin Feng's pain was reduced a lot, and he felt a powerful breath, swimming in every bone in his body, and his flesh seemed to be much stronger than just now.

Using the last bit of strength, Lin Feng turned around and sat up, and began to meditate cross-legged, his body gradually released a golden light, and the bones, muscles, meridians, and even blood vessels of his whole body were all revealed in the golden light.

Yu Ling saw it clearly, Lin Feng's body was absorbing these golden rays at full speed, and as the golden light entered Lin Feng's body, his physical body once again raised in level, reaching the level of the peak of the knot pill, and there was a possibility of entering the Yuan Infant Stage at any time.

However, because Lin Feng's strength realm has not yet reached the Yuan Infant Stage, the physical body itself naturally cannot cultivate on its own, but after washing the marrow, Lin Feng's physical realm is at least on the earth, and there are few people who can compare to it.

The pain disappeared completely, Lin Feng finally breathed a sigh of relief, and when he opened his eyes, he found that a handsome man was already standing in front of him, looking at him with a smile.
