Feng Jiu couldn't eat or sleep in a state of sorrow, and his hair fell out every day.

On this day, Feng Jiuqing and the warriors who protected her came back as soon as it was dark, and she had to see the wheat, so she didn't wait for Marien and their hunting team.

At this moment, I am boiling lard with Xingyue, preparing to make pancreas!

The lye was soaked in plant ash a few days ago, and after filtering it many times, it was still not clean, and the water was yellow, which was somewhat similar to the color of the pancreas she used before.

I've just started boiling the lye and lard together.

"Nine acres!" Yana's voice sounded not far away, and in the blink of an eye, she had already arrived in front of her, holding a large leaf in her hand and wrapping something, and put it in front of her like a baby: "This, look what this is." ”

Feng Jiuqing's eyes suddenly lit up, and he looked at the thing in front of him excitedly: "Sweet potato, where did you get the sweet potato!" ”

"This department was changed by the Tu tribe to Shangqiu, and it happened that we bumped into them when they came back, and the leader didn't ask for their tolls, but asked for five offices, and let me bring them." Yana thought she hadn't seen it, so she quickly brought it to her.

Feng Jiuqing looked at the sweet potato in front of him, why was it cooked?

"The leader said, look at whether you eat or plant!" Yana looked at her expectantly, her eyes burning.

"This ......" Feng Jiuqing frowned and poked the sweet potato twice: "Yana, why is this cooked?" ”

"Cooked? The potatoes we get in exchange for eating have always been like this! Yana didn't know why, but fortunately, she reacted quickly, and immediately thought of something: "Jiuqing, you mean, the potatoes they gave us were cooked after they were cooked?" It's like the beasts we hunted, roasted and eaten, right? ”

Feng Jiuqing nodded, and he was quite enlightened: "This is ripe, and the cooked ones will not sprout in the ground, and only raw sweet potatoes can be planted and cultivated." ”

"No wonder." Yana nodded knowingly: "We used to use the potatoes in exchange for bury them in the ground, but they didn't sprout, and after they were finally pulled out, all the meat in them was eaten by insects, and the leader thought that our planting method was wrong, let me show you." ”

"Let's eat this!" Feng Jiuqing didn't expect them to be so tendoned, can't they tell the difference between cooked and raw?

But on second thought, they haven't seen sweet potatoes before, and they probably think that sweet potatoes are born like this!

From this point of view, these tribes on this continent are really iron roosters one by one, pit people with technology, pit people who can plant, and the most bitter ones are tribes who have no technology and can't plant.

Like what.

Wind chasing department.

This Shangqiu tribe is really lacking in virtue, and what they exchanged for was cooked sweet potatoes.

"How much can a sheep get for this thing?" Feng Jiuqing broke one open, gave Yana half of it, and gave another piece to Xingyue.

Yana caught it.

Xingyue didn't dare to answer, and shook her head violently.

"Let's eat!" Feng Jiuqing put it in her hand: "I have eaten too much of this thing, you can also taste it, and when we also plant it, you can eat as much as you want." ”

The yield of sweet potatoes is large, more than that of wheat and rice, and it is easy to survive, and it is not picky about the soil quality, if she can get seeds, she guarantees that in two years, the tribe that can be planted is everywhere, and she will not worry about eating.

Xingyue swallowed her saliva and looked at Yana cautiously, she nodded, and then took a careful bite.
