Ten minutes later, Li Ang stopped pulling the wheel and took out the eight glass test tubes on both sides of the wooden disc.

Pour all the supernatant liquid into a casserole, pour a small amount of clay into it, and stir constantly.

White clay has a large specific surface area and pore volume, has special adsorption capacity and ion exchange properties, and can adsorb vitamin B12.

When the white clay has almost absorbed the solution, Li Ang puts the white clay into a clean fine cloth bag and drains the water.

Then pour the white clay adsorbed with vitamin B12 into a porcelain bowl, add water, and stir vigorously for 20 minutes.

Finally, filter the stirred solution and pour it out.

A high-content vitamin B12 solution was obtained—because vitamin B12 is easily decomposed when exposed to light, everything had to be done in a dark room.

"It's done."

Li Ang looked at the less than one bottle of clear liquid extracted from dozens of pieces of pig liver, breathed a long sigh of relief, and said to Yan Yundang: "This is the special substance extracted from pig liver.

This substance can relieve anemia and promote development - it can be given to poultry and livestock first, mixed with bran and fed for a long time. It should promote the rapid growth of livestock and observe the effect."

"No need."

Yan Yundang was also very straightforward. After looking at his set of procedures, he could see clearly that Li Ang did not add anything special to the solution.

Only the pig liver, water, and clay prepared by Yan Mansion will not be poisoned - and there is no need for it. He himself knows the severity of Yan Yundang's pernicious anemia.

"Give it to me."

Yan Yundang took the bottle and asked, "Can it be taken orally?"

"Just take it orally."

Li Ang nodded and said: "This medicine needs to be taken for life, once a day for seven days. After seven days, it should be taken every half month, and no process can be changed.

If it takes effect successfully, you will feel significantly better within two or three days, your appetite will increase, and your tongue pain will subside."

Oral vitamin B12 can also relieve pernicious anemia to a great extent, but the effect is not as good as intramuscular injection, so it must be taken in increasing amounts to prevent the recurrence of anemia.

"Should I take it for life..."

Yan Yundang grinned, "I don't know how many years I can live."

After saying that, he raised the bottle and drank it in one gulp, wiping the corners of his mouth.

"Father,"

Yan Lin subconsciously asked: "What does it smell like?"

"What else could it taste like? It tastes like blood and water."

Yan Yundang glanced at his son and muttered: "It's better than expected.

That’s right,”
