A gluttonous meal is finally over. But there was no nice and peaceful atmosphere at the dinner table.

"You kid ...... again I was lazy again, and I was busy for a long time, and I ...... Just these few dishes?" Du He leaned back in his chair, tilted his body and grinned and shaved his teeth, looking at Du Teng from the corner of his eyes.

"I ......"

"Say, you...... Is it in the stove room itself...... Eat it secretly? honestly...... Explain" Su Mu kept hiccuping and rushed to speak.

Du Teng even found that Su Mu also showed a swallowing performance in the middle, as if he had swallowed something that came out again. He was about to take the opportunity to speak, but the result was ......

"Brother Du is also stingy. So many people, only made such a small meal. I can't eat at all" Jiang Ziyue complained above, but her hands were constantly rubbing her stomach below, and her back was straight.

"You...... You guys...... , you look at these people. Uncle, you'd better say something fair" Du Teng couldn't stand it anymore, and asked Uncle for help with great grievances.

"Du Gongzi, you ...... Don't you still drink that spoonful of soup in your bowl?"

Burst!

Hahaha!

Ouch, my belly...... Don't let me ...... Laugh!

Du He, Su Mu, Jiang Ziyue, and the three broke out. Slap the table, slap the table, hug the belly full, and there is a more ruthless, on the ground, roll around, roll around.

Du Teng looked coldly at the three of them laughing with tears and tears in their eyes. Then he said softly, "Let's go, uncle." I almost forgot. The three-flowered thousand pages on the stove should be cooked."

Whoosh!

The three people who were still in a state of madness a moment ago disappeared in an instant!

And then......

"Bunny, where's the pie?"

"The surname is Du, you come over to me!"

"Brother Du family, you lost this bag of yuan stones."

"Let's go, uncle. Come with me to the city. Take a walk after dinner and live to nine hundred and nine" After speaking, Du Teng pursed his lips and walked towards the door leisurely.

Walking out of the medicine hall and coming to the street, Du Tengming wandered around aimlessly. But in my mind, I have been communicating with Xiaobai. Because Du He's voice in the hall just now was really loud, although he was in the stove room, he also listened to it word for word.

So now the question arises. Was this Qi Fu Pill refined by him?

In a broad sense, it certainly is. Isn't that his own? But what if they let him refine it again? What should they do? Do they still have to hide and hand it over to Xiaobai? This is not a safe way for a long time after all.

But if you want him to refine it himself, he really doesn't have a fire vein. I hadn't thought of that before. That's how it can be good.

Du Teng had a headache for a while. It's a dead knot.

"Babies, don't rest. All gave dad ideas and spoke positively"

"I'm not free, I'm experimenting"

"Don't make noise, delay me watching "Meteor Garden""

"Blackie, Blackie. What's your opinion?

......

"Okay, you bear kids, it's the other thing I do, I'm ...... today."

"Wow, Daoming Temple is so cute. Are you a pig? I like it," Red has been brainwashed again.

"It's over, it's completely hopeless. This soap opera is so lethal. It's simply unbelievable...... Wait, are you a pig. Are you a pig? Yes, are you a pig! Hahaha, I've figured out a way! Xiaobai, I've got a way!"

"Oh, Dad, what do you think?"

"I'm definitely not a pig. I'm a human being. What's the biggest difference between humans and animals?

"I know. And then what?"

"I can't use your strong laser particle analyzer, but I can use something else. Is there a firework charm? This can also be burned and heated."

"Gee, that's really a solution, and it's worth a try. I think the odds of success are great."

"So what are you waiting for. Hurry up and find a place to give it a try," Du Teng turned his head and said a word to his uncle, and ran away in a hurry after something. Then I found an inn, asked for a room, closed the door and began the experiment.

Fortunately, it was a success when refining it before, and a lot of medicinal materials were saved. Du Teng took out all his brains, and then took out a Dan furnace that Du He gave him at that time, and began the preparations before refining.

First of all, I re-acquainted myself with various medicinal materials, and then carefully watched the video recorded by Du He when he was refining it several times.

Finally, he analyzed the various steps and precautions recorded against Xiaobai, and played back several times frame by frame. It wasn't until he confirmed that he had memorized it clearly, and Du Teng was finally going to start refining the pill himself for the first time.

In fact, he is not nervous at all now. Because he believes that Xiaobai is here, even if something goes wrong with him, he will definitely remind himself in time.

Du Teng took out the fireworks talisman.

"First burn and heat for 5 minutes. Note that there are ten seconds left. Okay, when the time is up, put in 30 ml of chai pine stalk liquid, three iron cloud roots, and stone devil insects...... Wait, stop!"

"Why didn't it stop, I'm not wrong"

"Wrong, the temperature is not enough. The temperature at which the flame is heated is not enough. At that time, when Grandpa Du heated it to 5 minutes, the temperature in the Dan furnace was already 91 degrees Celsius. But now the temperature in Danding is only 39, which is too much worse. I just remember to remind you of the time and steps, but I forgot the most important flame."

"That's not going to work? yes, it's only 39 degrees, so it's too much worse. ”

"It's not just the temperature, you look at how many runes are left in your hand. This alchemy has only been carried out for less than one-fifth, but only one-third of your rune is left. It's not enough at all. ”

"Oh, really. I think...... Hey, there you have it. Why am I so stupid? The fireworks talisman of the Enlightenment Realm is not good, I still have the Blue Flame Talisman of the Enlightenment Realm. This higher-level rune must be more powerful. Hey. I'm such a genius. Hurry up, try again"

"Good. Then again. Activate the combustion heat for 5 minutes. Don't rush to put the medicine this time. Look at the temperature first, but you are also ready for the herbs, listen to my prompts"

"No problem"

"Good. Countdown to 10 seconds. 10，9，8...... 2, 1. The temperature is 79 degrees Celsius!

"If it's not enough, keep heating it. Let's see when it's 91 degrees. You're keeping an eye on it," Du Teng began to nervous inexplicably at this moment.

5 minutes passed. 85 degrees.

Another 5 minutes, 87 degrees.

Obviously, the temperature rises significantly slower the further you go, and it can even be said to slow down exponentially.

5 minutes, 88 degrees.

10 minutes, 89 degrees.

17 minutes, 90 degrees up.

Attention!

This attention is a full 26 minutes.

"Okay! 91 degrees. OK. Put firewood pine terrier...... Stop!"

"Why did it stop again?" Du Teng couldn't stand it anymore. After tossing and turning here for a long time, it was about to start, and it was stopped again.

"What's going on, Xiaobai. It's okay."

"Dad, look at your runes"

Du Teng paid attention to it and immediately understood. Less than a quarter of the runes remained.

The temperature is enough, and the runes are not enough.

Refining a Dan, why is it so difficult.
