"I believe that as long as the soil that has been purified once is purified a second time, or even a third time, we are not far from success!" Cai Youyou said excitedly.

After coming up with a solution to the problem, she immediately regrouped and returned to the lab to begin a new round of soil purification.

Because the content of harmful substances in the soil samples used in the second round of soil purification was already negligible, Cai Youyou had to take other ways to supplement the food for the Light of Life.

Those vegetables that are planted and contain a small amount of toxic and harmful substances can not be wasted, and can be returned to the field as organic fertilizer, on the one hand, to increase the fertility of the soil, and on the other hand, to provide nutrients for the survival of the microbial life light that uses harmful substances as food.

In order to protect those precious rays of life, she also reduced the amount of light of life at the beginning of the experiment.

However, Rao did so much preparation work in advance, and in the later stage, there was still a phenomenon that the light of life began to die and decompose due to lack of food.

Seeing those lovely and respectable microorganisms who dedicated their lives to the cause of soil purification until they died, and returned their bodies to the land in the form of fertilizer and nutrients, Cai Youyou somehow felt a little depressed in his heart.

It was Mo Xun who thought of a very critical question in a flash.

"Cai Xiaona, the light of life feeds on the toxic and harmful substances in the soil, and without the toxic and harmful substances, that kind of microorganism can't survive, am I right?" Mo Xun suddenly said with a twinkle in his eyes.

Seeing that Cai Youyou still didn't understand what he meant, but nodded ignorantly, Mo Xun smiled slightly, stood up, and took Cai Youyou into his arms: "If the light of life begins to die and decompose, doesn't it mean that there are no harmful components in the soil, doesn't that mean that we have succeeded?!" ”

"That's right!" Cai Youyou's eyes also lit up with excitement: "I'm sad for the reduced number of light of life, but I neglect such an important thing!" ”

As she spoke, she walked over to the soil sample with her lab equipment, ready to take a sample for testing, to test the content of harmful components in the soil, and to reuse the soil that had been purified for the second time for planting.

Glancing at Cai Youyou, who was fiddling with the test tube and the rubber head dropper, Mo Xun smiled slightly, didn't bother her, quietly exited her laboratory, took out her mobile phone and made a call.

"How's everything I want you to prepare? My wife admires the beauty of simplicity. So I hope that in our wedding, we don't incorporate too many elements so as not to dazzle people, and to ensure that the effect of the wedding is ......"

In the golden autumn of October, Mo Xun is doing his best to prepare for his wedding.

On Cai Youyou's side, the soil that has been purified twice has been used for a new round of experiments to cultivate vegetables and crops.

Different from the last time, the kind of transplantation after letting go, according to the method of using harmless soil to grow vegetables to manage the model, this time, Cai Youyou spent more effort, in every stage of vegetable growth, real-time monitoring, everything is careful, always pay attention, for fear that it will repeat the mistakes of the past, wasting those brought from the earth, finally cultivated, precious light of life.
