Song Xiaodong and Sun Yiyi soaked in the laboratory for five days, during these five days, the two of them ate and lived in the laboratory, and when they were tired, they nested on the bed in the experiment for a while, and then woke up and continued the experiment.

Sun Yiyi has never been so serious, in the past five days, she has not seduced Song Xiaodong once, and all the thoughts of the two of them have been placed on this drug.

This is different from the medicine that Song Xiaodong practiced last time, there is a ready-made method of refining medicine, and the medicine is also a finished product, so there is no need to try it little by little, so the progress should be said to be fast.

The main difference is that there was no high-tech heating equipment like this before, so the mastery of this kind of heat and the kind of pure handwork will require countless attempts.

The other is the mastery of true qi, this kind of alchemy, the most important thing is to integrate its own true qi into the medicine, and use the true qi to cooperate with the reaction and polymerization of the drug.

This is also the true qi cultivation of Song Xiaodong and Sun Yiyi, and now they have reached a very high level, so they can do such a thing, if it was placed a few months ago, even if there is no way, Song Xiaodong has no way.

The two had already forgotten everything, and their hard work paid off, and on the fifth day, after using up the last medicine, the two finally succeeded in refining two pills.

This is a real elixir, two yellow pills with a metallic luster, round and without a single flaw, they are all pleasing to look at.

The rich medicinal fragrance emanated from the two pills, making Song Xiaodong and Sun Yiyi both drool involuntarily.

"Is this it?" Sun Yiyi turned her head, her neck was a little stiff, and she looked at Song Xiaodong.

Song Xiaodong swallowed another mouthful of saliva and said, "It should be." ”

Sun Yiyi hesitated for a moment and said, "That...... Shall we eat?"

Song Xiaodong nodded and said, "Eat, I'll eat first, I'll come and see the effect of the medicine, and you can help me protect the Fa." ”

Sun Yiyi nodded and said, "Okay, then you eat first." ”

In this matter, Sun Yiyi doesn't have to rob it at all, Song Xiaodong's body itself has strong drug resistance, and he has a better control over the efficacy of the drug, if there is really any accident, he can still save himself, and she doesn't have such an ability at all, if she eats it first, it is completely disadvantageous.

Song Xiaodong took a deep breath, picked up a pill, and stuffed it directly into his mouth.

The pill looked very hard, but when it reached the mouth, it melted directly into saliva and turned into a sweet liquid, which slid directly down the throat and into the stomach.

A rich aroma immediately filled Song Xiaodong's mouth, this was definitely the best thing Song Xiaodong had ever tasted.

But Song Xiaodong was not in the mood to experience the taste of this medicine, so he sat down cross-legged directly, mobilizing his true qi and feeling the changes in this medicine.

When the medicine entered the stomach, it was only a little time, and it turned into a stream of air, and Song Xiaodong only felt that his stomach was like a balloon that had suddenly been blown up, and it was about to be burst.

That kind of discomfort really made Song Xiaodong almost scream.

Hurriedly mobilized his true qi, directly guiding the air flow in his stomach to his limbs and enter his meridians.

That true qi was pervasive, and it quickly rushed into Song Xiaodong's whole body, which made Song Xiaodong's stomach relieve a little, but the place where the true qi flowed seemed to directly break the meridians, burning hot, and piercing the pain of the heart.

With strong perseverance, Song Xiaodong guided those true qi little by little, integrated those true qi into his true qi little by little, and expanded his meridians.

I don't know how long it took, Song Xiaodong slowly opened his eyes.

"Ah!" Sun Yiyi sat in front of Song Xiaodong, staring at Song Xiaodong all the time, as soon as Song Xiaodong's eyes opened, she immediately exclaimed, that kind of gaze was as sharp as a sword, as if it could directly see through her heart, so that she couldn't help but avoid Song Xiaodong's gaze.

However, Sun Yiyi immediately met Song Xiaodong's gaze again, but Song Xiaodong's gaze seemed to have returned to its usual state, and his expression was even more restrained, as if he was more like an ordinary person.

"The divine light is restrained!" Sun Yiyi exclaimed in surprise.

Song Xiaodong smiled slightly and said, "It seems that the benefits are great." ”

Sun Yiyi said: "This is definitely a great improvement, hurry up, I want to eat it too." ”

Song Xiaodong nodded, and told Sun Yiyi about his reaction when he took the medicine.

Sun Yiyi kept them in her heart one by one, and then picked up the medicine and put it in her mouth.

Sun Yiyi knew all the situations, so she had prepared in advance, and with Song Xiaodong protecting the Dharma beside her, she was much smoother than Song Xiaodong.

"It's done!" Sun Yiyi opened her eyes with a sweet smile on her face.

"It's done!" Song Xiaodong also had a bright smile on his face.

"Then shouldn't we celebrate?" Sun Yiyi's face showed a charming smile.

"That's a must. Song Xiaodong smiled and nodded.

"Then what are you waiting for?" Sun Yiyi threw herself directly into Song Xiaodong's arms.

"Ahh

The two of them jumped up all of a swoop, and then rushed directly into the bathroom, both of them had a faint layer of dirt on their bodies, and they washed it off several times before they were rinsed.

This is the impurities discharged from the bodies of the two people, which also shows that the drug is very effective, and ordinary drugs have absolutely no such effect, and the impurities in the human body are discharged, that is, the human body is healthier, and the strength will be more improved.

The two hugged each other, it was a hot kiss, and after it was good, Sun Yiyi looked at Song Xiaodong and said, "I don't know if it's okay this time?"

Song Xiaodong said: "Then try it." ”

Sun Yiyi smiled and said, "I can't ask for it." ”

The two of them got out of the bathroom and rolled on the bed, but they were still very careful, and they still went directly to the back door, this position, so as not to have any accidents.

But after a while, Sun Yiyi said depressedly: "How can this be?"

Song Xiaodong also fell depressedly on Sun Yiyi's side, and said: "It is estimated that I have improved, you have also improved, and then your ability has become stronger, now that I go through the back door, I feel that the suction is greater than before, and I almost can't bear it." ”

Sun Yiyi pouted and said, "Our ascension should be the same, why is it even more difficult now than before?"

"Your special ability may have one more bonus than the improvement of normal true qi, so if our strength has been improved in such a balanced way, then we will never have a chance, and even one day, we will not even be able to go through the back door. ”

"I'll go! I knew I wouldn't have taken the medicine just now, ahhhh
