After obtaining the Black Water Vajra Pill, Liu Yi and Liu Lan did not stay long, but rushed straight to the outside of the Black Emperor City. In the north of the city, Liu Lan set up a teleportation circle that could send the two of them back to Purple Lake City.

Liu Lan took Liu Yi and flew quickly in the air. She had just flown a short distance when her eyes turned slightly and she said, "Someone is following us."

Liu Yi's heart trembled when she heard this, and she immediately asked, "Is he also a sixth-level heavenly master?"

"Yes." Liu Lan nodded and said with a slightly solemn expression, "He has been following us since we left the Shaoling Chamber of Commerce."

Liu Yi frowned when she heard this. She knew without asking that it was the Shaoling Chamber of Commerce. They had not interacted with anyone else, and no one else would follow them.

Liu Yi frowned. The person following him was probably sent by the third young master just now. After all, a mere black water diamond pill is not worth the Shaoling Chamber of Commerce to snatch back. Thinking of this, Liu Yi asked, "Can you get rid of it?"

?”

"I'll give it a try." Liu Lan's voice was solemn. After saying this, Liu Lan's flying speed increased sharply, passing over the Black Imperial City, and flying quickly towards the outside of the city.

The sixth-level Celestial Master who was following behind him was startled, but he immediately sped up to follow him. One after the other, the two sides were chasing each other at a distance of a full mile. The person following behind did not seem to want to close the distance.

After arriving outside the city, Liu Lan quickly came to the teleportation circle and waved her hand to activate the teleportation circle.

The people following behind were stunned. They didn't expect that the other party would actually enter the teleportation circle and leave. They quickly increased their speed to the extreme and rushed towards the two of them at full speed. ??

However, he was too slow after all. How could he catch up at a distance of a full mile? Liu Lan and Liu Yi were seen walking directly in, and then the teleportation circle was instantly closed.

boom!

The sixth-level Celestial Master who was following him fell hard to the ground with a loud noise. Looking at the teleportation circle that had disappeared in front of him, the sixth-level Celestial Master looked gloomy, but there was nothing he could do. It seemed that he could only go back and report the result.

Purple Lake City.

In the city lord's palace, a golden light lit up, the teleportation circle opened, Liu Yi and Liu Lan jumped out from it, and landed firmly on the ground.

"Huh... it's so dangerous." Liu Lan gasped a little while flying at such a high speed, and said with some fear, "The opponent's strength is better than mine, but fortunately the distance is far enough, otherwise it would be difficult for us to escape."

"He can't catch him, right?

?" Liu Yi breathed a sigh of relief and then asked.

"We can't catch him." Liu Lan shook her head and said, "He has not entered our teleportation circle, and it is impossible for him to sense the teleportation circle I set up, unless he is a seventh-level heavenly master. But even a seventh-level heavenly master cannot

It is possible to open my magic circle, let alone know where we are going."

After hearing Liu Lan's words, Liu Yi felt relieved and said, "Let's go find Sister Yang quickly!"

"Okay!" Liu Lan nodded and said.

Yang Meiren was in the city lord's palace, and the two of them soon found their location. When Yang Meiren knew that the two people had actually succeeded in buying the Black Water Diamond Pill, she couldn't help but be stunned, and Bingshan's face rarely showed a smile.

"How did you buy it? How much did it cost?" Yang Meiren asked.

Liu Yi roughly recounted what had happened. Yang Meiren was slightly startled when she heard it, and finally asked, "In other words, you got the Black Water Diamond Pill back without spending anything?"

Liu Yi smiled and said, "Of course, there is no business that can't be negotiated without me, Liu Yi!"

Looking at Liu Yi's proud look, Yang Meiren smiled again. No wonder Lu An had a particularly different feeling for Liu Yi among the many women he brought. Although this woman is not a heavenly master, she is really powerful.

"This way we have the capital to negotiate." Yang Meiren looked at the elixir and said, "Now we only need to wait for the day of the conference. If Lu An can really refine another one, our negotiations will definitely be beneficial."

Liu Yi and Liu Lan both nodded happily, now they just have to wait for the results of Lu An's refining of the elixir.

——————

——————

Inside the house, refining the elixir was more troublesome than Lu An imagined.

Lu An has been mentally prepared for alchemy. After all, it is a seventh-grade elixir. It is normal that he cannot refine it, but the difficulty of refining is still beyond imagination. The most uncomfortable thing for him is the control of the flame.

As the saying goes, the flame that succeeds or the flame that fails, the Nine Heavens Holy Fire is extremely powerful, and the refining process is very difficult.

The last two materials do not need to be purified, but are put in at the last step of refining, but

Just refining the first dozens of materials gave him a headache. After a full day, he didn't even successfully add the third material.

Although his flames are powerful enough, his control over the flames is not good enough. This is not because his control over the flames is poor, but because his level is fundamentally insufficient. In fact, Lu An's control over the flames is far beyond that of other firemen of the same level.

Attribute Celestial Master, but compared with the seventh-level Celestial Master, there is still a big gap.

After trying for a full day, Lu An had to give up. He knew that if he wanted to successfully refine it, he would have to resort to tricks.

Since he couldn't control it as he imagined, he used Xuan Shenbing to make a model he wanted and filled it with flames to achieve the control effect he wanted. But this kind of thing is simple to say, but difficult to do.

It was extremely difficult. He tried to make the model again and again. Within four days, Lu An could not count how many times he failed.

Lu An felt that he had changed at least a thousand models to burn the liquid to the temperature he wanted. In the process, he did not waste materials, but kept repeating experiments on the materials that failed the first time. After all, although refining

It failed, but the concentration of the liquid remained the same.

When refining the seventh-grade elixir, the temperature is not static, but changes with the addition of materials and the passage of time. Lu An adapted little by little and made models for each stage little by little. Starting with the third material

After success, reaching the tenth or thirtieth level, Lu An was very cautious and did not dare to waste anything.

During the days of refining alchemy, no one bothered him. In an extremely quiet environment, Lu An was devoted to it without distracting thoughts. During this period, Yang Meiren came outside his house many times, but only glanced at Lu An through the window a few times.

An's figure left. Everyone was busy with their own affairs, and the war continued.

On the twentieth day after returning to Purple Lake City, which was also the penultimate day of the Zuntian Gate's conference, Yang Meiren, Yang Mu, Liu Yi, and Liu Lan gathered together again and stood guard outside Lu'an Gate.

No matter what, we must set off tomorrow morning, otherwise there will not be enough time to rush to Zuntianmen. Once we miss this event, we will miss the best opportunity for negotiation.

The four of them stood guard outside Lu An's door. After discussion, they decided to only give Lu An until sunset tonight. If Lu An hadn't finished yet, they could only interrupt and interrupt the alchemy. ??

"Lu An is only a fifth-level heavenly master. It is still too difficult to refine a seventh-level elixir." Liu Yi frowned slightly and said in a deep voice, "Although it is difficult for Zuntianmen to change the direction with a black water diamond elixir,

But it’s not necessarily impossible. I’m going to Zuntianmen this time, there’s no difference between negotiation and business, I can help.”

The other three people nodded slightly when they heard Liu Yi's words. It is true that Liu Yi's business acumen cannot be matched by them, and they also believe in Liu Yi.

"It's already noon. Why don't Sister Yi and Xiao Mu go to have dinner first? Sister Yang and I will stay here," Liu Lan said.

Yang Mei and Liu Lan were both heavenly masters of level six or above and no longer needed to eat to replenish their energy. However, Liu Yi and Yang Mu looked at each other and shook their heads.

"I want to wait for him to come out." Yang Mu said softly.

The three of them didn't say anything after hearing this. The four women just stood at the door, waiting for Lu An to appear. However, the four of them had been waiting here all morning and there was no movement. I'm afraid they really have to wait until the evening to call Lu An out.

.

However, just when this idea appeared in the minds of the four people, a huge wave of heat suddenly swept from the room!

This heat instantly hit the wall and surged out from the gap in the door. In just one breath, the steel door turned red, and the terrifying heat rushed straight towards the four of them!

"Be careful!" Liu Lan said subconsciously, and quickly took action to protect Liu Yi and Yang Mu. But before her, Yang Meiren had already taken action, and immediately a transparent life wheel barrier appeared around the four of them, blocking all the heat.

However, a sudden change suddenly made the hearts of the four women move. Could it be that...

boom.

The door was suddenly opened, and a wave of heat rushed out. The heat wave quickly disappeared, leaving only Lu An standing at the door with sweat on his face.

Yang Meiren immediately removed the barrier, walked up to Lu An and asked, "How was it? Was it successful?"

Although Lu An's face was covered with sweat and his face was very pale, he showed a big smile, stretched out his hand, and saw a black pill with ice and fire patterns appearing in his hand.

"Fortunately, I did not disgrace my life." Lu An couldn't help the joy in his heart, but he held his stomach and said, "But from what you said, I'm really hungry."
