Deep dark caves, some cold feeling, summer into the cave, with fire folders lit torches, along the mossy ladder, slowly down.

The light of torches can only illuminate the distance of several meters around them. Fortunately, in summer, the power of consciousness can easily penetrate the walls. Therefore, even if you can't see the distance, you can also rely on the power of consciousness to "sense" the situation around you.

In the sense of consciousness, this stone ladder, down do not know how far, the hand of summer Chen touched the stone wall lightly, unexpectedly felt a trace of warmth, and the more down, the more intense the feeling of warmth.

"Bright?"

Suddenly, Xichen saw a glimmer of light in the dark hole, and even in the air, you can feel the hot and dry breath, as if there was a flaming flame burning in general, resulting in a sudden rise in temperature.

"Mother said, there is a fire in this cave. Is it near where the fire is?"

The purpose of this trip to Lianyun Mountains was to use fire to temper the body and make Tianyan Jiuyun practice faster.

So the summer day quickened its pace and headed for the bright light below.

After walking all the stone ladders and stepping onto the flat ground, there is no need to light a torch in summer, because there is a bright spot in front of us.

It's a cave with some stone chambers, and under it there's a tiny lava river, horrible lava, flowing into the ground, disappearing into the darkness, perhaps erupting somewhere.

"It's amazing that there's underground magma!"

Summer's eyes are full of surprise. Magma can only be seen inside the volcano or deep underground. It was unexpected that such a spectacular sight was found in this cave.

Such a peculiar landscape may be just a surprise to ordinary people and should be appreciated, but it is a perfect "happy land" for the summer day when Tianyan Nine Forges were practiced.

The hot breath can help summer Christmas to temper the body repeatedly, speed up the progress of Tianyan Nine Forging, and enhance its strength rapidly. After all, Xia Chen has just stepped into the Six-fold Exercise, which is the time when the strength has been greatly improved.

"Huh..."

Xia Chen breathed a sigh of relief, and finally found the ground fire cave, and the environment here is really very suitable for him to exercise. The rolling magma of Napoh can reach a temperature of thousands of degrees, even if it is a strong copper and iron bone, it will melt instantly when it falls down.

Summer Chen naturally does not enter the magma to exercise. It's not a practice, but a pure death. He just uses the terrible temperature emitted by magma to exercise near the magma.

Some of the dry food that will be prepared in summer is put in a stone chamber in the cave. He is ready to live in the cave for a long time.

"It's not too late to start practicing now!"

Summer Chen took a deep breath and gradually calmed down the chaotic mood. Then he sat cross-legged beside the magma and his whole body began to move slowly.

The temperature of magma is thousands of degrees, and near the magma, the temperature is not low. The skin of summer is almost baked red by hot temperature. However, with the movement of Qi and blood, the surface of summer is like a layer of blood light, covering the whole body.

"Tianyan Nine Forges!"

In summer, he began to run Tianyan Nine Forging. After reaching the six-fold of the body, he was the first to run Tianyan Nine Forging. The most important thing is the muscles of the whole body. The muscles are in the body. They are very difficult to exercise. It takes a long time to exercise to make the muscles full of strength.

In summer, Tianyan Nine Forging is very magical. By using the power of Qi and blood, it can continuously impact the muscles. Besides, beside magma, the hot breath is filtered by Qi and blood, which blockades the heat toxin outside, leaving only pure heat, which slowly penetrates into the muscles.

Pain, incomparable pain!

When a lot of heat slowly penetrates into the muscles, the whole body seems to be burning up in summer, especially inside the muscles, as if there is a filament of flame, burning constantly.

This kind of pain is almost tormented in the fire, as if living under the burning of the fire, even in the always determined summer day, it is somewhat unbearable, trembling all over, pale face.

But Xia Chen stuck to it. He let out a roar like a wild animal in his mouth. He was suffering as hard as he could. And Tianyan Nine Forging, also slowly played a role, in addition to pain, a silk of crispness, also appeared in the summer muscle, which shows that his muscle has begun to exercise, and also very effective.

Six-fold refining of meat is to train the muscles. It is only when every inch of muscle in the whole body is tempered once that meat can be considered as refining. Moreover, summer is not just a time to practice, but a full nine times to practice!

"Ah ah..."

Suddenly, Summer Chen couldn't help it anymore. He looked up to heaven and roared. He also stood up quickly and left the magma edge until he entered the stone chamber, which made him feel a little better.

"
