Li Tian didn't want to be disturbed, so he waited quietly on the side. Finally, after a full quarter of an hour, Xu Mengli made a decision in his heart and put away the alchemy furnace with a wave of his hand.

"Miss Xu•••••• what's wrong?" Li Tian asked softly.

Li Tian's voice suddenly appeared, startling Xu Mengli, who had been in deep thought, Xu Mengli gently stroked his chest, turned his head and said: "It may be that there is something wrong with the attributes, I have been thinking about the matter of the demon pill before, but I didn't think of the conflict of attributes, so this time I failed." ”

"Oh, I see. Li Tian didn't understand alchemy, but this time he came out to repay the favor, so he simply helped people to the end, Li Tian thought for a while and said: "In this way, why don't we look for it nearby and see if there are any spirit beasts with other attributes, you can try a few more times." ”

"Good. Xu Mengli seemed to experiment with the thoughts in her heart, so she nodded, and the two packed up their things and continued to walk towards the depths of the fog forest.

Originally, there were no humans in this 'Gray Fog Forest', there were many spirit beasts, and it shouldn't be too difficult to find spirit beasts with other attributes. It's a pity that Li Tian ignored one thing, that is, ten days ago, the large-scale beast hunting of the 'Xuannan Sect' army.

Hundreds of people from the 'Xuannan Sect' hunted beasts in this range together, and almost all the spirit beasts in it were hunted, and the other spirit beasts also knew that this area was very 'dangerous', so they all fled, Li Tian and Xu Mengli did not gain for a while after searching for dozens of miles.

"This gang of black boys. Li Tian sighed in his heart, so he had to take Xu Mengli to continue to go deep into the fog forest.

Finally, after nearly a hundred miles away from the camp, they found a fire-type spirit wolf. Seeing the spirit wolf, Li Tian immediately vented his unsmooth anger on the spirit wolf's body, and the 'Ruyi Spear' dispatched for the first time, with an amazing earth-based spiritual light, and struck at this second-order medium spirit wolf.

Pitiful, the spirit wolf is also the overlord of this forest, majestic, but he didn't have time to react, he didn't even move, he was pierced by the angry Li Tian, and even his intestines flowed out. Li Tian stepped forward, dug out the fire-based demon pill with a dagger, cleaned it, and handed it to Xu Mengli.

After Li Tian searched for such a long time, Xu Mengli was a little reluctant, but at this time, alchemy was the most important, so she took over the elixir and refined it again. This time, Xu Mengli was more careful, and even took out a few books from the storage bag and looked through them, and finally selected dozens of spirit grasses and refined them with this fresh fire-type demon pill.

The fire ignited again, and in order to increase the firepower, Li Tian cut down many gray plants and set them on fire. Not to mention, the gray plant is hard, but it also provides a lot more firepower, much better than ordinary wood, which is a surprise. However, Xu Mengli couldn't take care of these at this time, and all her energy was invested in alchemy.

Xu Mengli accurately controlled this spiritual grass, put them into it at the right time, saw the change in the color of the alchemy furnace, felt the fluctuations of spiritual power in it, and controlled the pace of his alchemy. Among them, a large amount of heat emanated out, making Xu Mengli's face like a peach blossom, and with a bright red robe, it was even more delicate.

In the end, Xu Mengli took out the fresh fire demon pill again, looked solemn, and then threw it into the alchemy furnace!

"Whew!" The fire increased suddenly, and the temperature suddenly increased, even igniting the leaves of the surrounding gray plants. And in this high temperature, the alchemy furnace trembled violently! All kinds of spiritual light flickered in it, emitting bursts of glow, and in the end, it was like a seven-colored rainbow, extremely gorgeous.

The huge spiritual power fluctuations once again caused a strong wind, producing an astonishing coercion, which spread all around, and even made Xu Mengli's face pale. Li Tian looked at Xu Mengli with some nervousness, not knowing if this weak girl could persevere, alchemy is also hard work.

But at this time, Li Tian saw another side of Xu Mengli: usually, Xu Mengli looks weak and gentle, she is a delicate girl, but in alchemy, in the amazing pressure, in the scorching heat, Xu Mengli showed her strong perseverance, even if the whole body was trembling violently, even if the high temperature burned her skin, she still insisted on alchemy!

The momentum of not admitting defeat made Li Tian see the strength of this girl's heart.

Finally, the alchemy was about to end, and this time the experiment seemed to have been successful, which made Li Tian breathe a sigh of relief. But at this moment, a fiery red aura suddenly flashed violently! Then, with a 'poof' sound, just like the last time, at the last moment, the elixir was scrapped!

A burst of black smoke was rising, and Xu Mengli's tired face couldn't help but have a look of disappointment. Ignoring the high temperature of the alchemy furnace, she hurriedly turned the lid of the furnace and carefully watched the situation in the smoke. After a while, Xu Mengli already had a judgment in his heart, and couldn't help but subconsciously say: "Last time, it was the demon pill of the water system and the 'Blue Whale Grass' that clashed, but this time, it was the demon pill of the fire system and the 'Tianxuan Grass' that clashed, and the improved prescription still had many shortcomings••••• it seems that the fire system is not good, and I have to try the gold and wood ••••••"

Hearing this, what else did Li Tian hesitate about?

He decided to continue helping this strong and persistent teenage girl. So, after the two cleaned up the alchemy furnace, at Li Tian's insistence, the two continued to move forward••••••

Then, Li Tian hunted a gold-based python and a wood-based ape, but the alchemy failed, making Xu Mengli look at Li Tianshi with an apologetic face. And at this time, Li Tian, an alchemy layman, also knew that in order to refine this new healing elixir, what was actually needed was an earth-based demon pill.

The development of new things is like this, it takes countless attempts and countless failures, so Li Tian has no complaints and starts the final journey: the spirit beast of the earth system.

Li Tian sincerely helped Xu Mengli, Xu Mengli was completely immersed in his alchemy, so neither of them paid attention, after several consecutive advances and hunting beasts, they were already far away from the camp! At the same time, they also went deep into the gray fog forest, this area, even the scouts in the army had not come.

Capturing the spirit beasts of the earth system cost Li Tian some means, not because of how powerful the spirit beasts of the earth system are, but because they are often hidden in the earth, and it is really difficult to find them. Finally, after some searching, in the afterglow of the setting sun, Li Tian found an earth-based spirit mouse.
