The system asked me, a weak woman, to challenge a saint

The cold air generated by the Tianbing Sword's self-destruction quickly spread around. Even though the ghost ghost was far away, he still felt the biting cold. He couldn't help but shudder and quickly activated the protective aura for defense.

You Ye seemed to be well prepared. He retreated a mile away and activated several defensive formations against ice attributes that he had already prepared.

The Sin Killing Judge seemed to have expected it, and he and You Ye also retreated to a mile away, and activated the defensive formation and body protection aura.

The Netherworld Ghost Elder protected Shiting, holding on to the self-destructive power of the Sky Ice Sword. He saw that his protective aura was frozen by the cold air and was about to burst. He hurriedly used the Netherworld Soul Locking Chain, and the five dragons came out together, stabilizing After living in the Four Symbol Position and Tianyuan Position, he could barely resist the cold air.

Xiao Yuhan was also very satisfied with the power of the modified Tianbing Sword in the field of divine bells. After she obtained the formula of Lao San, she was not very interested in the elixir in it, but she was interested in the method of injecting cold air into the magical weapon. The method is very interesting.

She quickly improved the sword-making techniques in Tianbing Swordsmanship, and used Tiangang Qi to replace the Yin Fire of the earth veins to seal the extreme yin and cold power in various spiritual plants into the Tianbing Sword. During the first test, Xiao Yuhan only released half of his power. Youye instinctively had a premonition of something bad when he was observing from a mile away, and retreated two miles before he could barely withstand the erosion of the cold air. When he came, he saw The temporary wooden house was completely frozen into an igloo and then shattered.

Xiao Yuhan did not dare to conduct a full-power experiment. She was afraid of destroying the three people's cave and disturbing Shou Xin's healing. When Xiao Yuhan felt very satisfied, Xiao Xuan still put forward her opinion, "Xiaohan, I am very happy that you can improve Tianbing swordsmanship by yourself now. However, Tianbing swordsmanship is based on the power of the five elements after all, and now there is a lack of one Menmu-type skills cannot bring out the full power of Tianbing swordsmanship."

Although Xiao Xuan's words made Xiao Yuhan feel a little regretful, the matter of martial arts was something that could only be met by chance, and the top priority now was to improve one's own hard power.

This time, facing the Netherworld Ghost Elder, Xiao Yuhan just detonated a Sky Ice Sword carrying [-]% of its power. The power of the Tianbing Sword could actually force Netherworld Ghost Lao to use his trump card. Such power was enough to give him and the ghost temple monks a certain degree of self-protection.

Xiao Yuhan noticed that after the Tianbing Sword self-destructed, everything within a two-mile radius turned into a frozen land. The cold air filled the surrounding air and condensed into a desolate-looking ice mist. This ice mist continues to spread, covering a larger area of ​​spiritual plants.

The spiritual plants could withstand the general cold, but their strong branches and leaves began to wither quickly, and the flowers withered in the cold wind. The lush green patches gradually turned into a dead silence under the cover of ice mist.

The withered spiritual creatures continued to decay. Under the shroud of ice mist, they became twisted, rotten, and lost the breath of life. The originally lush trees turned into twisted dead wood, and the grass turned into a gray.

The scene within ten miles became extremely desolate, and the cold area almost turned into a frozen wasteland. Xiao Yuhan observed all this, silently feeling sorry for the sacrifice of these plants.

The four of them had now moved to another open space ten miles away, and the Netherworld Ghost Lao also brought his stone pavilion with him.

Looking at the desolation not far away, Netherworld Ghost Lao fell into deep thought. He walked to Xiao Yuhan's side, with a serious expression on his face, and said in a deep voice: "Fellow Daoist Chen, I have thought of a possible solution. According to the records of ghost Tao classics, in extremely yin places, extremely yin earth veins will be born, and every day At the core of a Jiyin Earth Vein, there is an extremely powerful Yin Fire.

As far as I know, the Asura battlefield now belongs to the underworld, and there must be an extremely yin leyline during this period. The extremely yin leyline will condense ghosts. According to your previous experience, the dark side near the sacred tree fits this characteristic. "

Xiao Yuhan felt happy when she heard this, feeling that this news might be able to solve their predicament. She asked: "Great Elder, how can we find the place where the Yin Fire of the earth's veins is located?"

The ghost ghost thought seriously for a moment, and then said: "Did you see no trace of any spiritual plants in the dark side near the sacred tree before?"

Xiao Yuhan nodded.

The ghost ghost continued: "Fellow Daoist Chen, do you know that the vitality of spiritual plants is far beyond human imagination. Even in harsh and extremely cold places, spiritual plants will still appear. The reason why you cannot see spiritual plants is, It's because of those ghosts.

However, the Yin Fire of the Earth Vein naturally restrains these ghosts. Even the most powerful ghosts will avoid the Yin Fire of the Earth Vein. Therefore, in the entire extremely Yin Earth Vein, only the Yin Fire will have spiritual plants remaining. "

Xiao Yuhan was filled with hope after hearing the answer given by Netherworld Ghost Elder. She decided to follow the advice of the ghost ghost elder and go with You Ye to find these extremely precious spiritual plants and further determine the location of the Yin Fire in the earth.

Not far away, after the ice fog gradually dissipated, Xiao Yuhan's eyes were naturally attracted to the dilapidated scene.

In the bleak scene, she saw a faint glimmer of green. A small plant appeared on the dry land. Although its branches and leaves were sparse, they still stretched out tenaciously.

What surprised Xiao Yuhan even more was that there were more seeds ready to move on the surrounding land, germinating quietly in the cold soil. These young plants are working hard to grow in the frozen soil, and their green color is slowly spreading, bringing a touch of life to this withered land.

Xiao Yuhan was shocked and admired when she saw the tenacious vitality in these extremely cold environments. These plants face extreme cold and dryness, but still struggle to grow and persist in their existence.

Even if the surroundings are desolate, they are still looking for warmth and light and trying to survive. This tenacity of vitality makes Xiao Yuhan deeply admire the power of vegetation. She understands that although this Asura battlefield is full of death and destruction, the power of life is still seeking the hope of survival.

After returning to the cave, Xiao Yuhan decided to find the Yin Fire in the earth vein as soon as possible. After discussing with You Ye, she decided to set off early the next morning. This time, Xiao Yuhan did not notify Shou Xin. On the one hand, Shou Xin's soul was damaged and needed to rest for some time. On the other hand, it was useless if too many people went there. Moreover, the fewer people knew about some of Xiao Yuhan's methods. The better.

The reason why she brought You Ye with her was mainly because of her judgment of danger and insight into details. The last time she was able to detect the surveillance of the Tribulation Realm monks at a glance, this made Xiao Yuhan full of confidence in You Ye's insight. Although Judge Sin Killer's prediction ability seems to be higher than that of You Ye, he is the confidant of the Netherworld Ghost Elder and will not cooperate with others casually.
