Now it can be seen that the refining speed of inner alchemy and sea sand is slower than that of ordinary medicinal materials.

The fusion process will definitely not be too easy!

What Long Xiaopang originally planned to complete in a day, now the refining time has become unknown.

"Little girl, just this time, you must stop..."

Long Xiaopang prayed in his heart, and there was no turning back when he opened his bow. Now he can only trust Ye Yuxi.

In half a day, Ye Yuxi raised the temperature of the sea sand and the inner alchemy to an equal level, and began to control the fusion of the two.

As Long Xiaopang expected, when Haizhisha and Neidan touched together, the two did not fuse together.

No matter how Ye Yuxi squeezed it with the different fire, there was always a layer of cold air between the two.

That layer of cold air not only hindered the fusion of the two treasures, but also quietly offset the temperature of the strange fire.

Ye Yuxi frowned, and the power of her palm sped up a bit, and the spewing strange fire became faster and more violent.

The layer of cold air between the sand of the sea and the inner alchemy was eliminated bit by bit, but the speed... can only be described as scrambling.

Three days passed in a blink of an eye.

Ye Yuxi was still standing in the middle of the alchemy table, her arms kept protruding forward, and flames gushed out from her palms, hitting the inner alchemy and the sand of the sea continuously.

Compared with three days ago, Hai Zhisha and Neidan have been fused by two-thirds.

The sand of the sea was originally in the shape of sand grains. After these few days of refining, it has now completely turned into blue cold air.

The cloud of cold air wrapped around the inner alchemy, and carefully entered the inner alchemy little by little under the refinement of the strange fire.

With mental strength, one can feel that a light blue mark has formed on the inner alchemy, but this light blue mark flickers, not as stable as other red snake patterns.

Feeling the blue snake pattern, Long Xiaopang's heart relaxed a bit, he could merge, at least half of this step was successful, the rest...

Long Xiaopang turned to Ye Yuxi's eyes again showing worry.

The rest depends on whether Ye Yuxi can last till the end.

After three days and three nights of refining, Ye Yuxi's eyes were already bloodshot, and her cheeks were a little pale, which was completely a symptom of mental exhaustion.

Even though Ye Yuxi is a strong earth spirit, even if Ye Yuxi has the strength of a seventh-rank pharmacist.

But the high-intensity refining medicine for dozens of hours in a row, even an iron man can't stand it!

How long did Ye Yuxi practice, and Long Xiaopang stood aside. Compared to Ye Yuxi, Long Xiaopang was slightly better. Although his face was full of exhaustion, at least his mental strength was not overdrawn.

"Master Long, do you want me to help Yu Xi?" Bai Jinyi walked over from the side, looking at the bloodshot beauty, Bai Jinyi's eyes were full of distress.

"Little Bai, listen to me."

Long Xiaopang's voice suddenly became a little lower, and he said word by word: "Little girl is in this situation, you can make a move, but what you get in exchange must be the scrapping of the inner alchemy. , is only half the battle."

Bai Jinyi stared blankly for a moment, and immediately realized why Long Xiaopang suddenly urged him to meditate and practice a few days ago!

At that time, Long Xiaopang had already anticipated the current situation.

That's right, the task of merging the inner alchemy with the sand of the sea is only half completed, and the next step is to refine the Nine Yin Flood Oil!

"I understand, Master Long." Bai Jinyi responded, and with a cruel heart, he turned and walked towards Baiyutai.
