Liu Feng has searched the history of the earth, and many regimes are fighting for spices, which is enough to explain the importance of spices.

Liu Feng brought some spice seeds to cultivate and plant, but it will take a few years to be popularized if they are enough to be sold as goods, and the production period of the raw materials for some spices is too long.

Then substitutes are very necessary. It is near the Forbidden Mountains to the west. There are so many species. It would be too stupid not to search and use it.

Besides, some spices can be used as seasonings, and they are also medicinal materials.

"I haven't found it to be poisonous for the time being, but there is a difference in taste." Tooth pouted, thinking that he had tried the difference between the two spices, and his mouth felt weird.

"Give me some of the two kinds of spices." Liu Feng said lightly. He would take it back to Earth for testing, so that it would be safer. There are still three medicinal powders that will be analyzed, and it will be fully promoted if there is no problem.

"Yes." Tooth nodded.

"Last time, did you read a document I gave you?" Liu Feng said indifferently.

He was talking about the experiment of hybrid plants. He wanted to hybridize some plants on the earth with other worlds to see if they could be infected with the characteristics of the plants on the earth, just like the hybrid rice on the other side of the earth.

"My subordinates have already read it and arranged for someone to test it." Fang Fang reported that he now has a lot of things to test.

"Don't worry about that." Liu Feng nodded, he also asked, it will take a few years to produce results in hybridization.

Chapter 0672 Excited Yuffie.

More than a dozen hot air balloons were fluttering in the sky, and they were being led by Leia's dozen orcs of the bird race, guiding the correct course.

"It's great, it's really great." Yuffie's pink eyes glowed at the stove and the airbag above.

No wonder she was excited. After all, her dream of flying was realized in this way. Before, she wanted to create a flying device by herself, but she didn't expect to experience the joy of heaven in advance.

"Why is this? You can fly by burning fire?"

"What's the reason for this? Won't the fire burn what's on it?"

"Can you actually carry so many people, can you fly back to the Aoli Kingdom?"

Lying in the hanging basket, Yuffie frowned and muttered to herself, just like a demon, making Yakura next to him sigh bitterly.

"What a sin!" Yi Li lowered his head and sighed in disappointment. He knew why Yuffie was so obsessed with flying into the blue sky, so that he could fly back to the Kingdom of Auli to see his mother.

You must know that Yuffie, as one of the five strange women in the capital, is amazed by her skills, and the weapons designed are very beautiful, and are sought after by many bounty hunters and nobles.

But since he wanted to go to the Aoli Kingdom to see his mother, he has been immersed in designing some kind of flying equipment, which is impossible in his opinion, but now he has let him lose this idea, because he is in the sky, which makes Yuffie. More curious and excited.

"Yuffie, come and drink some water." Yak Lee shouted with the bamboo tube in hand. Yuffie has been studying the hot air balloon since he got on the hot air balloon in the morning.

"You drink." Yuffie shouted without looking up. She still didn't understand the principle of hot air balloons. How did such a huge airbag fly into the blue sky?

"Uncle Yili, don't worry, maybe you can really take this ride back to the Ori Dwarf Kingdom?" Princess Lucy persuaded her, she knew Yuffie's troubles and knots.

"Hey..." Yi Li sighed and said helplessly, "What if I could fly back to the Ori Dwarf Kingdom?"

His wife was the daughter of a nobleman. If he took Yuffie back, he would probably be kicked out of the house or caught, and then he would get rid of his father and daughter, so as not to embarrass the nobleman.

More importantly, is this Xiyang City Lord willing to give them a hot air balloon? It's impossible to think about it.

"This..." Princess Lucy was at a loss for words, she didn't know how to comfort her, because Uncle Yakiri was so right.

She looked down at Catherine, who was lying in the hanging basket and sleeping on her lap. Thinking of the meeting between the two of them last night, Catherine cried like a child, and a hint of softness flashed in her heart.

"Huhuhu..."

Princess Lucy listened to the twitching sound of the bellows, and looked at Jones squatting and twitching the bellows. The leopard-eared girl didn't dare to stand up, and people who were afraid of heights couldn't be hurt.

For the first time, she knew that Jones was afraid of heights, which made her feel incredible. She had to know that Jones gave her the impression that she was not afraid of heaven and earth.

"Drink some water." Eliza handed over the kettle.

"Is it coming?" Princess Lucy looked up at the elf's dry face from the wind, reached out to take the kettle, and asked, "Eliza, do you want to take a break?"

"It's almost there." Eliza shook her head, glanced at the sleeping Catherine, and whispered, "After the two hills in front, it is the territory of Xiyang City."

"That's good." Princess Lucy breathed a sigh of relief, floating in the sky, she also felt uneasy.

"Huh? Is it coming?" Catherine opened her eyes in confusion, cracked her mouth, and yawned.

"I've disturbed you, drink some water." Princess Lucy unscrewed the lid of the kettle and said softly, "It's almost time for Xiyang City."

"Really?" Catherine sat up abruptly, her golden eyes flashing with joy, and she looked closely at Eliza.

"Yeah." Eliza nodded and teased, "Do you want to see Master Liu Feng immediately?"

"Well, there is." Catherine's cheeks immediately rose to a touch of pink, and she pouted and said, "I just want to quickly thank Your Excellency Liu Feng for your rescue."

"Perhaps." Eliza chuckled lightly, without exposing the thin-skinned Catherine.

"It's time to thank Your Excellency Liu Feng." Princess Lucy's golden eyes flashed with a strange light.

"Yuffie, why are you still studying?" Catherine blushed and immediately changed the subject.

Although she really missed Liu Feng and wanted to see Liu Feng right away, the girl's restraint made her embarrassed to show it.

"Yuffie, stop researching." Eliza shook her head and shouted, "When you get to the base, why don't you ask Your Excellency Liu Feng for advice?"

Is this hot air balloon so easy to study?

"Can I really ask for advice?" Yuffie's pink eyes widened.

Such an artifact that can fly into the sky may not necessarily be said if you ask for advice. Yuffie doesn't think she has much face.

"After you arrive, you will know if you try it." Eliza said softly.

"Okay." Yuffie sighed, rubbed the slightly dizzy eyebrows, and used her brain a little too much.

"I really didn't expect that Your Excellency Liu Feng actually came up with a device that can fly." Princess Lucy said with a sense, it's only been a few months?

"There are even bird orcs to help." Catherine also sighed. After all, when she came to Xiyang City before, she never saw any bird orcs, no, except for Frey.

"Let's follow, is it really all right?" Yi Li asked a little worriedly.

"Uncle Yili, don't worry, Your Excellency Liu Feng is a good person." Catherine patted her chest and assured.

"Yeah." Yi Li nodded bitterly, he abandoned everything in the capital, and moved to another place, hoping to make them have a good life.

"Huhuhu..."

"Get ready, it's here." Leia's cold voice came.
