Under normal circumstances, the price of a fourth-order lower level talisman is about 5000 to 7000 spirit stones.

But now it's his own request. Zhou Yang can't accept Jiang YuYan's giving him half of his merit in exchange.

He spent 32000 points on the merit of the yellow sand gate and exchanged three fourth-order lower level talismans from Jiang Yuyan, two of which were defensive talismans and one was an auxiliary talisman for trapping the enemy.

In this way, with the merit value previously spent on exchanging the "Youming blood contract", Cao Wenjin gave him 90000 merit value, and now there are only 58000 points left.

After changing what he wanted, Zhou Yang didn't stay in Huangsha gate much. Even if he rode an eagle lion beast back to his family.

"Xiao Jiu, you came back just in time. I've studied the sand camel you made these days and found that your idea is good, but it doesn't work in the right place."

"The camel skateboard you are making now is too heavy. Even if it is pulled by two Shatuo animals, it will take at least ten days to recover."

"That won't work. We should use weapon refining to reduce the weight of the skateboard. It's best to reduce it to the extent that a Shatuo can pull a car, so as to quickly and effectively migrate the population."

On Yuquan peak, as soon as Zhou Yanggang came back from Huangsha gate, the old patriarch Zhou Minghan took him to talk about the "sand camel car".

The migration of mortals is an urgent event for the Zhou family, and Zhou Minghan is also very interested in it.

When Zhou Yang heard him say this, he was also surprised and said, "don't hide from your great grandfather that your grandson had this idea, but your grandson's knowledge is limited and he hasn't found a feasible method. Do you have any idea when you talk about this now?"

"At present, I have thought of two methods. One is to start from the material. When I visited the immortal world, I knew that there was a family producing a second-order wind attribute Lingjin [wind Copper] over Pegasus oasis. This metal is less hard than refined iron, but as light as willow. It has excellent elasticity and toughness. We can buy a batch of this material as the main material of skateboard."

"The second is to start from the craft of refining utensils. We can use wind copper as the main material and cloth [Qingling] prohibition on the skateboard to further reduce the weight of the car body."

Zhou Minghan slowly said his idea, then looked at Zhou Yang and said, "your father is going to attack the third-order alchemist recently, so I can only do the purchase of wind Copper myself, and the family will give it to you."

"The grandson understands."

Zhou Yang nodded, but he didn't argue about such a small matter. He just took out two of the three four-level talismans he had exchanged for and gave them to the old patriarch Zhou Minghan.

Zhou Minghan is a nine storey cultivation of building a foundation. Only by using a fourth-order talisman can he maximize the power of the talisman and leave mana to continue fighting.

Like him, if you want to maximize the power of the fourth-order lower level talisman, you have to inject half of your mana into it, so you will be very passive in a battle.

After Zhou Minghan left his family and went to Pegasus oasis to buy wind Copper, Zhou Yang temporarily lived in his cave for cultivation.

So in the past few months, Zhou Minghan, who went out to buy wind Copper, has not come back. Zhou Xuanhao, who closed the door and attacked the third-order alchemist, has good news.

"How's it going? Ying'er, what do you think of the [Yangyuan pill] refined for your father? The appearance has reached the normal third-order level? "

On the Yuquan peak, Zhou Xuanhao and Zhou Yang's father and son looked at Xiao Ying nervously, while Xiao Ying stretched out two slender jade fingers, clamped a pale white elixir, and came up to his nose to sniff more than once.

Xiao Ying originally cultivated hybrid food crops in the farmland at the foot of the mountain. After leaving the customs, Zhou Xuanhao hurriedly called her to the mountain to help identify the third-order elixir he refined.

Originally, he and Zhou Yang could judge whether the refined elixir reached the third level.

However, after he finished the pill this time, the number of pills was only two, and the color of the pill was also a little wrong, which made him have no confidence in his heart. He must ask Xiao Ying, a third-class alchemist, to confirm it for himself.

"There should be no problem. The number of pills produced is small, which is very common in the new third-order alchemist. So was my daughter-in-law at the beginning. As for the color of pills, it may be that you burned some of the liquid when you were refining pills."

Xiao Ying put down the pill between her fingers, smiled and spoke out her judgment.

As soon as she finished speaking, before Zhou Xuanhao could speak, Zhou Yang looked at him and said, "Dad, I said it must be all right? Now Ying'er has said so. You can rest assured! "

"No, I still have to verify it!"

Zhou Xuanhao suddenly grabbed the elixir from Xiao Ying, and then took it directly.

"Dad... Aren't you fooling around!"

Zhou Yang looked at this scene and was very angry.

How can you take this pill indiscriminately?

If this elixir is really unqualified, won't it hurt yourself?

"Zhou Lang doesn't have to worry. The elixirs of [Yangyuan pill] are mild. Even if there is something wrong with the refined elixir, dad has enough time to force the medicine out of the body."

Xiao Ying gently stretched out her hand to hold the Taoist companion's hand, and calmly made a voice to enlighten him.

Zhou Yang felt relieved when he heard the speech.

And Zhou Xuanhao also opened his eyes about a quarter of an hour after taking the elixir. His eyes were full of joy and shouted: "yes, the efficacy is similar to the [Yangyuan pill] I used to take. This is really a real third-order elixir!"

Then he looked at Zhou Yang with a smile and said, "yang'er, you are busy first. For your father, go back to refine the medicine first."

"My father is really not reassuring!"

Zhou Yang looked at the back of Zhou Xuanhao, who hurried back to the cave in a hurry, and smiled bitterly.

Then he looked at the Taoist partners around him and asked, "Ying'er, how are you doing in cultivating hybrid crops? But what's the good news? "

"At present, there is no big progress. Zhou Lang, are you sure that the cross breeding of two crops of different varieties can really cultivate higher yield crops?"

Xiao Ying's eyes flickered with doubt, but she finally took the opportunity of Zhou Yang's inquiry to ask her doubts that she was embarrassed to say these days.

She carried out many experiments according to the ideas provided by Zhou Yang. The results showed that the cultivated crops were either difficult to eat or the yield was many times lower than the original yield, which made her doubt about Zhou Yang's hybrid crop cultivation plan and whether it could really succeed.

However, after hearing her question, Zhou Yang said confidently, "there must be no problem with my idea. Ying'er, you don't have to worry. Just take your time. We immortals have plenty of time to do it!"

Hearing his confident words, Xiao Ying's doubts immediately disappeared. She couldn't help nodding and said, "well, I believe Zhou lang."

It must be difficult to cultivate a high-yield crop of hybrid varieties from scratch.

However, Zhou Yang believes that with the various means mastered by immortals, as long as they follow this direction, they will certainly succeed.

Not to mention anything else, just in accelerating the growth of ordinary crops, even all the means used in his previous world can not be compared with the "spring breeze and rain" of the second level lingzhifu.

It doesn't matter that Xiao Ying failed to test dozens or hundreds of times. When she tested hundreds or thousands of times, Zhou Yang believes that there will be good news.

So half a month later, the old patriarch Zhou Minghan who went out to buy wind Copper finally returned to the family.

Seeing this, Zhou Yang immediately put down all his work and studied the transformation of "sand camel" with Zhou Minghan.

As Zhou Minghan said, the two skateboards of the "sand camel" are long and wide, and there is enough space to arrange "light and smart" prohibition for them.

After more than a dozen experiments, they successfully put a ban on a skateboard.

But don't think that even if the self created magic weapon is successful, if the self created magic weapon is so simple, any tool refiner can do it.

They can add a "light and smart" prohibition to the skateboard. In fact, they refine the skateboard as a large flying sword, just changing the soup without changing the medicine.

But anyway, after adding the "light" ban to the skateboard, their original intention was achieved.

Two skateboards made of wind Copper and refined iron. After the prohibition of "Qingling" was added, the total weight of the whole "sand camel car" dropped to less than 2000 kg.

However, this still could not meet the requirement that a Shatuo beast pull a car, so Zhou Yang cut off the number of passengers of the "sand camel car" by 20 and turned it into a car to pull 60 people.

In this way, with the planned output of 40 "sand camel cars", it can carry 2400 people at a time. Moreover, it will not make the Shatuo beast too tired, and the speed will be one-third faster than before.

Zhou Yang and Zhou Minghan both breathed a sigh of relief after solving the big event.

"Well, now that the means of transportation for the migrant population has been completed, we can develop the new oasis after attending the foundation building conference!"

After Zhou Yang tested the performance of the newly manufactured "sand camel", he smiled and said his next plan.

Hearing this, Zhou Minghan frowned slightly, then nodded a little, and said, "the development of a new oasis really needs to be completed as soon as possible, but before that, we have to refine the third-order puppet beast quickly."

"What my great grandfather said is true, but I'm afraid you have to do it yourself to refine the third-order puppet beast. I'm afraid my grandson can only do it for you this time!"

Zhou Yang thought of the fact that his weapon refining technique was trapped in the third grade, and said so with depression on his face.

With his skill of refining utensils, the success rate of refining third-order puppet animals is too low, but the Zhou family has collected few refining materials in recent years. If you waste too much, you can't want to refine all three puppet animals.

Seeing this, Zhou Minghan couldn't help laughing and explained: "hehe, don't lose heart, Xiao Jiu. You're still young. It doesn't matter if you make a breakthrough in the art of refining utensils in a few years. This time, you and I refine third-order puppet animals together to accumulate some experience. It's also a good thing for you to independently refine third-order puppet animals in the future."
