"Go and call Mr. Song and go to Tianjin Port with me to raise funds for this fleet." Li You ordered that although the things brought back by the fleet this time were inconspicuous, he knew the power of this thing, and Song Yingxing was the one who could maximize the effect of this thing, so he should see it as soon as possible.

"Your Majesty, what kind of treasure is brought back by this fleet?" Wang Chengen is now familiar with Li You. He knows that asking about this kind of thing will not arouse the emperor's suspicion. At the same time, he is indeed a little curious. Chen Guangfu's fleet used to transport a large amount of gold back from Japan, and his Majesty was not so excited? Could it be that the elixir found from overseas fairy islands can make people live forever? But shouldn't Mr. Fu Shan accompany him? How could he choose Song Yingxing?

"Haha, it's indeed a treasure. You'll know it after you look at it." Li You didn't want to reveal it. Soon, Song Yingxing was taken to the palace. Li You immediately led his troops to travel to Tianjin. This action also aroused speculation from many important officials in the court. They were as curious as Wang Chengen. What exactly was the fleet brought back this time?

However, when this thing appeared in front of Wang Chengen and others, they were greatly disappointed. They saw that such things looked inconspicuous at all, like pieces of white, light yellow or brown soil, and emitted various odors, and did not look like treasures at all.

But Song Yingxing and Li You looked happy. Song Yingxing took off a small piece and crushed it and put it in his hand to observe, "Your Majesty, is this what you call struvite?"

"It is precisely because this species evolved from the feces and corpses of birds, bats and seals, after a long period of time. If it is scattered in the fields, it will greatly increase the yield of farmland. Of course, how to add and how much it should be added requires Mr. Song to carefully study. Once the function of this species is excavated, the people of our Ming Dynasty can stay away from hunger." Li You said that the main production areas of struvite are islands along the coast of Peru and Baja California, as well as areas where cormorants, pelicans and ganese are concentrated in Africa. They are also distributed on some islands in Southeast Asia. Struvite is rich in nutrients such as nitrogen, phosphate, potassium, etc., which can greatly promote land yield.

"Of course, in addition to studying these, Mr. Song should also analyze why this struvite is so useful." Now we can try to dig struvite as much as possible to serve as fertilizer, but these natural struvites will always be used up for one day, and the distribution of struvites is mostly remote, so we can only take care of nearby fields. If the people of the entire Ming Dynasty enjoy this benefit, we have to study artificial synthetic fertilizers. Of course, this will take a long process, but it is always good to make some preparations in advance, and there will always be times to be used in the future.
