In addition to helping Wang Kai resist toxins and making him more confident that he can pass Dugu Bo''s assessment, the body of yin and Yang actually has a greater advantage - greatly improving Wang Kai''s recovery ability!

Once the body of yin and Yang is successfully formed, Wang Kai''s body can achieve the state of combining Yin and Yang. From then on, Wang Kai''s recovery ability can be improved several times, whether it is soul power, spiritual power or qi and blood power! For Wang Kai, who has the ability to carry unlimited martial soul, this is naturally a desirable Constitution!

To give full play to the real power of infinite soul physique, Wang Kai not only needs a massive total amount of soul power, but also needs a powerful recovery speed of soul power! Otherwise, even if Wang Kai has many powerful martial spirits and soul skills, he does not have enough soul power to display them. Therefore, it is a good thing for Wang Kai to achieve the body of yin and Yang.

Although Wang Kai has obtained the soul skill of earth power, which provides him with a very strong recovery ability, after all, the soul skill of earth power also has certain limitations. If the battle site is located in the sea or sky without earth power, then this soul skill can no longer provide continuous recovery for Wang Kai. It is obvious, The body of yin and Yang has no similar problem.

Moreover, even with the soul skill of the power of the earth, it is good for Wang Kai to obtain the body of yin and Yang. After all, one plus one is greater than two, which can make his soul power recovery stronger. Why should Wang Kai refuse such a good thing?

Originally, Wang Kai was not prepared to condense the body of yin and Yang by taking these two fairy grasses at the same time. After all, there are many ways to condense the body of yin and Yang. Compared with condensing the body of yin and Yang early, it may be more beneficial for Wang Kai to win over the strong ones at the two peaks. However, at this point, Wang Kai has no other choice.

Take out the Qirong Tongtian chrysanthemum and Narcissus jade muscle bone. Wang Kai no longer hesitated, took off the petals of Qirong Tongtian chrysanthemum and the leaves of Narcissus jade muscle bone and stuffed them into his mouth.

Chewing gently, suddenly, a stream of sweet juice ran down his throat, and the fragrance overflowed. A stream of cold and warm energy entangled into Wang Kai''s muscles and veins.

Just like this, Wang Kai took all the petals and leaves. Soon, Wang Kai took all the stamens of Qirong Tongtian chrysanthemum and Narcissus jade muscle bone, mixed them together and swallowed them!

The roots of the bare Qirong Tongtian chrysanthemum and Narcissus jade muscle bone were taken back to the small plane. Wang Kai crossed his knees and did a good job, holding his breath and concentration. He madly refined the medicine power of two kinds of fairy herbs that constantly poured into the muscles and veins and belonged to one Yin and one Yang.

The medicine power of yin and Yang intertwined with each other in Wang Kai''s muscles and veins, and slowly flowed forward. Although the medicinal power of Qirong Tongtian chrysanthemum and Narcissus jade muscle bone is huge, they are extremely soft. They do not have too much impact on Wang Kai''s body and muscles. On the contrary, they moisten things, silently nourish the main muscles and veins in Wang Kai''s body, and rush away many small branches in Wang Kai''s body bit by bit.

At the same time, the soul power in Wang Kai''s body is also wrapped in groups of yin and Yang medicine power for refining. With the progress of refining, yin and Yang medicine power is constantly transformed into new soul power and Qi and blood power, so that the total amount and scale of soul power in Wang Kai''s body are growing at a visible speed.

With the refining of the medicine, the forces of ice and fire in the environment slowly poured into Wang Kai''s body along Wang Kai''s pores, and were refined by Wang Kai together with the medicine. Every time the power of ice and fire enters the body, Wang Kai''s body surface will flash a layer of light blue and red brilliance.

The power of ice and fire and yin-yang medicine have been continuously refined, and Wang Kai''s constitution has also been transformed into the body of yin and Yang!

......

Half a day later!

"Ding! You refined the heaven level nine herbs Qirong, Tongtian chrysanthemum, Narcissus jade muscle and bone, and obtained 75000 source experience!"

"Ding! You refine ice and fire energy in the environment and gain source experience + 2500!"

"Ding! You refine the heaven level nine herbs Qirong, Tongtian chrysanthemum, Narcissus jade muscle and bone to form a constitution - the body of yin and Yang!"

"Ding! The remaining source experience is 83500 points, and 50000 points are spent. The source experience is upgraded to level 56, and the remaining source experience is 33500!"

In the sea of knowledge, four system prompt sounds sounded one after another. Feeling the fading medicine and rising soul power in the body, Wang Kai slowly opened his eyes.

"Great, I succeeded!"

He nodded excitedly, and Wang Kai also sensed his physical condition. After successfully refining the two fairy grasses, Qirong Tongtian chrysanthemum and Narcissus jade muscle bone, Wang Kai finally successfully condensed his second special physique - the body of yin and Yang!

After refining the medicine in the herb successfully, Wang Kai''s body surface once again gushed out a layer of black dirt, emitting a dizzy stench. Slightly inspiring, Wang Kai smashed the dirt on the body surface, revealing the skin as white as jade and shining with beautiful luster.

Wash tendons and cut marrow! Taking the opportunity of refining fairy grass, Wang Kai completed the deepest refining of the body for the third time!

In addition, after refining these two fairy grasses, Wang Kai''s strength of Qi and blood and physical quality have also been greatly improved. Between one punch and one leg, Wang Kai feels the abundant and incomparable strength in his body! Compared with before refining fairy grass, Wang Kai''s strength has increased by about 50%, and his defense and agility have also increased significantly!

Not only the improvement of physique and soul power, but also Wang Kai''s spiritual power has been greatly improved after taking Xiancao! Although these two immortals pay more attention to improving the soul master''s physical body, as the ninth grade herb of heaven, they also have the auxiliary effect of increasing the soul master''s spiritual power! With the improvement of spiritual power, Wang Kai''s spiritual power has also naturally broken through the six functions of one heart and two states in a row, directly reaching the state of eight functions of one heart!

The only regret for Wang Kai is that the refining fairy grass provided him with too little source experience, which only promoted him one level. However, on reflection, this is also a very normal phenomenon.

First of all, in a short half day, the drug power in the two fairy herbs has not been fully refined. At least 70% or 80% of the drug power has not been refined and is hidden in Wang Kai''s body. It''s also urgent. Only by following up and slowly cultivating, can these medicinal powers deep into the flesh and veins be refined a little and gradually transformed into source experience.

Secondly, a large part of Wang Kai''s refined medicine was used to condense Wang Kai''s yin-yang body, but it was not completely transformed into source experience, which is why Wang Kai''s soul power was only improved by one level after taking enough two Zhuxian herbs.

After moving his body and adapting to the new power and soul power, Wang Kai came to the eye of ice and fire again. Later, if he wants to kill Dugu Bo, there will be a fierce battle. While there is still time, he is ready to pick all the most valuable natural materials and earth treasures in the eyes of Binghuo Liangyi.
