Geng metal is an extremely precious spiritual material, extremely strong and strong, and the best choice for refining spiritual swords.

Of course, Xinjin Yuanjing can also be used to refine weapons, but this is not the best way to use it. It should be used to heal people.

If the physical body is seriously injured, even if the flesh and blood is about to decompose and fall apart, the Xinjin Source Crystal can be refined into the body to repair the physical body and recover quickly.

It is said that by cultivating the body and transforming it into gold, you can gain quite a lot of benefits.

These secrets were exactly what Qin Sang saw in the classics related to physical training.

He is also a physical practitioner and has been paying attention to collecting classics in this area. Although he is practicing the demon clan method, he can also draw parallels. Unfortunately, there is no complete inheritance after all, and the so-called 'benefits' are not detailed in the classics.

Qin Sang didn't know, but Master Huaiyin knew it clearly.

By cultivating the physical body and converting the Xinjin Source Crystal into the body, the physical body can acquire a certain degree of softness, which is of great benefit in battles and killings.

However, for Master Huaiyin, the reason why the Xinjin Source Crystal is a must-have is for another purpose.

There is a secret technique in the temple, which requires Xinjin Yuanjing to practice.

Legend has it that the heaven and earth went through the five stages of innateness, five tai, and five stages from infinity to birth. Things with substance were born, and then to the initial separation of yin and yang, and the evolution of all things. All kinds of qi exist in the void, wandering and uncertain.

The same is true for Gengjin Qi.

When the energy of Geng Metal accumulates to a certain level, it forms Geng Metal, otherwise it will continue to flow in the heaven and earth.

However, compared to the boundless heaven and earth, this Gengjin Qi is too thin, and the monks cannot sense it at all, let alone collect it.

By practicing this method, you can refine the Xinjin Source Crystal into your bone marrow, and then use the mutual attraction characteristics of Yin and Yang to attract the free Gengjin Qi in the world into your body through the Xinjin Source Crystal.

Geng metal is extremely strong and strong, and it can be used to temper the bones of the whole body. After practicing to the extreme, Geng metal can be boned.

When the time comes, it will be easy to smash the magic weapon with your fist.

This secret method also has extraordinary significance to the path of Master Huaiyin. Unfortunately, Xinjin Source Crystal is rarer than Gengjin, and it is rarely born in Zhongzhou. Only a handful of saints in the temple have had this opportunity.

After entering the Wuxiang Immortal Sect, Master Huaiyin didn't have much ambition to fight for it. Unexpectedly, he found the Xinjin Source Crystal here. He couldn't miss it no matter what.

After listening to Master Huaiyin's simple explanation of the reason, Poison King knew that he was bound to get the Xinjin Yuanjing, so he agreed without hesitation and tried his best to help him win.

While talking, everyone chased Xing Pavilion and entered the depths of the Nine Earths Yuanmai.

At this time, the two sword stars at the back finally couldn't hold on anymore, their sword intent surged, and they exploded together!

The two sword stars were pulled together by the nine earth magnetism, and exploded at the same time. It was not as simple as accumulation, and the momentum was far more terrifying than the explosion of a single star just now.

'boom!'

Dazzling rays of light bloomed in the divine light of the Nine Earths, like a big sun shining in the sky, and the torrent was also swallowed up.

In an instant, with the Sword Star as the center, the surrounding nine-sphere magnetic light suddenly became turbulent.

The power of magnetism there was violent, and the danger instantly increased by more than one level.

Qin Sang paused for a moment. When he saw this scene, he didn't hesitate for too long. He poured all the spiritual fire in the fire lotus into the Mani Pearl without any reservation. The fire shield was a little thicker, and then he rushed in.

the other side.

Master Huaiyin and Poison King were also forced to stop.

The Poison King was secretly frightened. He had not noticed it before when he was far away, but only when he was close did he feel how shocking the explosion of the Sword Star was.

Feeling the violent power of magnetism inside, Poison King couldn't help but hesitate, but soon he heard the explosion of bones in Master Huaiyin's body, his blood and essence boiling, a layer of golden light flowing on his skin, and the Buddha's light outside his body flourishing.

This is the manifestation of strong Qi and blood.

Immediately afterwards, under the surprised gaze of Poison King, the energy and blood turned into a golden dragon, surrounding Master Huaiyin.

Master Huaiyin held the Heavenly Dragon in his hand, and the Heavenly Dragon roared in mourning. The divine light of the Nine Earths Yuan Magnetic Divine Light could not get close to him. He did not wait for the Poison King, and rushed toward the center of the chaos without any fear. He disappeared in the starlight in the blink of an eye.

Poison King cannot be as relaxed as Master Huaiyin, so he can only slow down and take every step.

Su Zinan and Mo Xingdao were not far away from them, and their speeds were about the same, but through the ubiquitous Nine Earth Elemental Magnetic, they could only sense each other in Mohu.

The sword star exploded, and Su Zinan narrowed his eyes to look at it, but his figure did not stop.

Mo Xingdao came closer, frowned, and like the Poison King, he also slowed down and stopped.

Su Zinan nodded to him and continued to move forward. The dragon's wire mesh above his head made a clanging sound, as if it was reaching its limit and could break at any time.

After getting out of Mo Xingdao's perception, Su Zinan secretly summoned the magic flag, and two demonic figures, Wu Lao and Yanshan Lao, appeared in front of him, turned into nothingness, and both threw themselves into Su Zinan's body.
