Tang San smiled slightly and compared his index finger to his lips, made a gesture of silence, and looked at the automatic alchemy furnace with his eyes.

Dugu Bo followed Tang San's gaze and saw that the gap in the lid sealed on the automatic alchemy furnace was constantly emitting light purple smoke. He was no longer surprised by this situation. Tang San often created some strange poisons that he couldn't help but admire, but Tang San refused to say some formulas, which made Dugu Bo very depressed.

Originally, he wanted to steal the sect, but Tang Yin invented the automatic alchemy furnace in front of him. He had no chance at all, because in his opinion, Tang San threw the medicinal materials in and set up some things he couldn't understand. Then he did whatever he should do. He had no chance at all.

The purple smoke from the automatic alchemy furnace condensed and swayed slightly above the copper cauldron. Dugu Bo's nose moved slightly. He had a very strong anti-toxic ability, so he would not be afraid. But he soon discovered that the purple smoke had no smell, and naturally he could not judge the ingredients. But for some reason, looking at the rising purple smoke, he felt a little chill in his heart.

As a soul master with poison as his ability, Dugu Bo knew very well what this feeling was. This was a kind of intuition that belonged to him. Only when there was a poison that could threaten his life would this feeling appear. What kind of poison was refining this little monster, even he felt threatened.

You know, although Tang San has refined a lot of poisons in the past six months and many clever medicines that amazed Dugu Bo, he has never had any situation like today that even he would be afraid. He didn't dare to disturb him now. The surname Suo sat down next to Tang Yin and the others and waited quietly.

Tang San's expression was a little solemn. After all, what he practiced this time was very important, so even though he knew that Tang Yin's automatic alchemy furnace was fine, he was still watching. As time went by, the purple smoke on the automatic alchemy furnace became thinner and thinner. At the same time, the color was also changing, from purple to white, and then from white to black. He went through a strange process.

Tang San watched as he added the medicinal materials three times in the process. This time he felt at ease, but his eyes remained on the real device. Tang Yin had given him the meaning of these values ​​seriously, and in order to make him better grasp, he also showed him the situation in the furnace. In order to make his brother understand the meaning of these values, Tang Yin had no idea about various units, and they had to mess with seven automatic alchemy furnaces. Now he used the ninth one, the eighth one because Tang San was not familiar with it...

Seeing Tang San's appearance made Dugu Bo's curiosity a little more. After drinking his tonic, he quietly used the poison skills to test the breath in the smoke.

However, no matter how he tried, he still couldn't find out what kind of drug the poisonous fog in the smoke was made of. Dugu Bo just vaguely felt that it should be a highly toxic mixed with multiple toxins and complement each other.

Could it be that this kid wanted to poison me Dugu Bo, thinking in his heart, otherwise, what would he do to refine such highly toxic drugs? However, he quickly gave up this idea. Not to mention that the relationship between the three of them is now a friend of both teachers and friends, even if Tang San really wanted to poison him, he would not refine it in front of him.

The refining process was extremely long. When the next morning, it was dawn and Dugu Bo was already feeling a little impatient. The black smoke on the automatic alchemy furnace finally gradually subsided and slowly returned to the automatic alchemy furnace.

"Success." Tang San jumped up from the ground suddenly, and the excitement in his voice was released uncontrollably. At this time, he was really a little lively and excited by his peers.

"Little monster, what exactly are you?" Dugu Bo couldn't help but ask.

Tang San then breathed a sigh of relief, looked at Dugu Bo, and said mysteriously: "This is a treasure. A treasure that kills human life. I can guarantee that even if you are hit by it, you will not survive three breaths. Of course, it is not threatening to you. You are rough and thick in skin and flesh, and it cannot enter your body. Let you see my masterpiece later."

"Then hurry up, brother, I can't wait." Tang Yin said. He knew that his brother was practicing something.

The King of Hell is the third super hidden weapon among the Xuantian Bao Record Concealer. Its power is naturally not to be said, but the reason why Tang Yin remembers him is not how strong it is, but its record is very average. In the end, he destroyed a Soul Saint Shinnian. Something that was obviously the peak of the appearance was very average compared to others.

Tang San then breathed a sigh of relief and looked at Dugu Bo and Tang Yin and said mysteriously: "This is a treasure. A life-threatening treasure. I can guarantee that even if you are an old poison, you will not survive three breaths. Of course, it is not a threat to you. You are rough and thick in skin and flesh, and it cannot enter your body. Let you see my masterpiece later."

More than ten blue silver grasses were soaring out at the same time, pulling the automatic alchemy furnace back to his side. He was not in a hurry, waiting for the copper cauldron to cool down slowly.

Tang San had already said this, and Dugu Bo could only wait. After half an hour, when the copper tripod completely cooled down, Tang San walked forward and carefully uncovered the top cover.

Seeing this, Tang Yin took out a gas mask he made from the space, and there was no way to take it. Last month, he was curious and did not take protective measures and was poisoned by the poison refined by his brother. At that moment, he seemed to have seen his relatives in his previous life. Fortunately, his brother discovered it early and rescued him.

But then Tang Yin had a psychological shadow. Whenever he saw that his brother had made any medicine, his first reaction was to bring the gas mask on.

Dugu Bo also used the poisonous power to protect himself, but he, Tang Yin, was much bolder. He leaned his head to look into the copper cauldron. In the copper cauldron, there was a very small metal abrasive in the center, surrounded by traces of dryness, which should be the residue of the medicine after it was dried. In the abrasive tool, four small needles that were only one inch long and were pitch black and dull.

"You have worked on it for a long time, it's this thing." Dugu Bo snorted angrily, "What's the use of this thing?"

Tang San smiled, turned his Xuanyu hand, carefully took out the mold, then took out a pre-prepared small jade box from the Mingyueye of the Twenty-Four Bridge, and poured the three needles in the mold into the three grooves.

"Is it useful to kill the poison that can kill the titled Douluo?" Tang San's eyes flashed with a scorching light. When he was in the Tang Sect, this kind of gaze only appeared every time he made a super hidden weapon.

Dugu Bo: "..."

"You brothers are poisonous, why can you either kill the titled Douluo or poison the titled Douluo? Is our titled Douluo aggrieved with your brothers or is this?" Dugu Bo roared.

There is no way, these two brothers are so annoying. They feel that the title Douluo is nothing in their eyes. He is very disappointed by this inexplicable remark that ruins his views, but this is not what makes him the most collapse. What makes him the most collapse is that he still feels it is natural at this time!
