"Are you sure?" Looking at the pothos vine surrounded by the six tree hearts, and then turning his head to look at Zheng Yuepo on the side, Xiao Han believed what he said in his heart.

When he planned to use legume plants to raise fields, Lu Yiming told him.

Grade 1 farmland can only be planted with Grade 2 crops at most, and if you plant Grade 3, it will not be possible to germinate at all.

This principle is universal.

In other words, the second-level farmland in front of you can only be planted with third-level crops at most, and both the germination rate and the harvest will drop by one or two percent.

According to this reasoning, it should be impossible for a level 2 farmland to cultivate a level 3 crop.

But why didn't Amy bring it up?

Although the six Yipin tree hearts are not very expensive, and he doesn't care too much about his current value, no matter how many resources he has, he can't waste them like this!

If these six Yipin tree hearts were given to Lu Yiming, he would be crazy with joy.

That guy has been cultivating Mangniu Jin for more than half a month, and he just broke through to the second rank of the mortal rank two days ago, and the reason for this is because he doesn't have enough energy crystals to cultivate.

The reason why he was able to break through now was precisely because he defeated Ushijima, and several of those minotaurs were in the product, so he was able to successfully advance with a few beast pills.

"Hey!"

The six tree hearts are wasted like this, this mistake is really a little speechless!

"Did Amy forget?" Xiao Han had to be so suspicious.

He even had a feeling that that little girl might not have a clear idea of the hierarchy of farmland.

At this time, Zheng Yuepo didn't know the depression in Xiao Han's heart, and said directly: "My lord, I'm pretty sure, I already knew it on the first day I became a planter, this is the most basic common sense, and it is impossible to remember it wrong." ”

Looking at the six tree hearts with some pity, Zheng Yuepo continued: "Low-level farmland does not have enough nutrients for high-grade crops to grow. ”

"And cultivating a level 3 pothos fruit will require more energy, not only life energy, but also some other nutrients, which level 2 farmland can't provide at all."

"So what now?" Xiao Han said depressedly: "Is there a way to solve it?" ”

"It's not that there is no way, but the chances of success are not high." Zheng Yuepo's eyes lit up and he said slowly.

After being promoted to a level 3 planter, it seemed as if some memories had been unlocked in his mind that didn't exist before.

Although this method may not work, it is still worth trying, and without waiting for Xiao Han to continue asking, he said directly: "Now, it is definitely impossible for that pothos vine to give birth to a level 3 pothos fruit." ”

"Why don't you transplant this pothos vine, along with the eight tree hearts around it and the soil underneath, into this level 4 farmland?"

"If within twelve hours, the transplanted pothos vine is not polluted by the undead energy, and the level 3 pothos fruit is cultivated in the level 4 farmland, there is still a great possibility."

"Okay, just do as you say." Xiao Han thought for a moment and said directly.

For now, this may be the only way, although it is only a dead horse as a live horse doctor, and it is better than no way.

Some people were called from Sumy, and in less than half an hour, a semicircular ball of earth with a diameter of two meters was dug up.

Under the soil ball, a lot of straw rope is used to prevent the soil from falling.

Xiao Han stepped forward, with a fierce force of both hands, he directly picked up the soil ball, turned around and walked to the side of the level 4 farmland.

In the middle of the farmland, a large pit with a diameter of more than two meters had been dug, and he gently put the soil ball into the pit.

Although I don't know if the pothos vine in the soil ball can last for twelve hours, I can only wait.

If it still doesn't work, you can only wait until the pollution in the level 4 farmland is cleared, and let Amy do it again.

Letting everyone go back and get busy, Xiao Han returned to his wooden house, clicked directly into the undead clan forum, and hung up one hundred and sixty first-grade corpse pills.

In less than two minutes, there were guys from the undead clan who left a message below, and the prices were quite reasonable, more than a hundred corpse pills were quickly replaced by more than a hundred crystal nuclei of other races.

Now that there are more resources in his hands that can be used for exchange, Ling Yi, Du Ziteng, Luo Finished Products, and Xiao Tie's blacksmith level should also be mentioned.

Ling Yi followed Feng Yonghe to study for a few days, but there were no drawings, it was not impossible to advance with his understanding, but it would take too long, anyway, the blueprints for the third-grade fish scale knife were not expensive, and the blueprints for the second-grade green steel sword were also bought together.

After Luo Chengcheng and Xiao Tie became Level 1 blacksmiths, the two of them were no longer in charge of smelting ore and forging skein bowstrings, and their current work was mainly to build mortal-level first-grade steel arrows.

The smelting of ore and the forging of the twisted string had been arranged for others, which increased the number of men in the ironsmith from six to eight, and four stoves were just enough.

The level 1 blacksmith is not very useful, and it must be cultivated to level 2 quickly, just so that they can build the Divine Arm Crossbow.

Yesterday, I have exchanged Ugin for ten catties of black iron to create two molds, and if necessary, I can complete 4 twisted wire bowstrings in one day.

But the other parts of the God Arm Crossbow can only be built by Ling Yi, Du Ziteng, Feng Yonghe, and Godot for the time being.

But Godot and Feng Yonghe both have their own things to do, so many mortal-level third-grade armor and weapons have not been created, so there is time to build a divine arm crossbow!

opened the search bar, searched for drawings directly by keyword, and soon found a post selling drawings, but they were all low-level drawings, there were many drawings of the Qinggang Sword, 50 gold coins each, and now there were more than 10,000 gold coins in his hand, Xiao Han directly bought ten.

"Hey, there are even drawings of the four-grade fine iron sword for sale!"

I didn't find the blueprint of the third rank of the mortal rank, but when he saw the blueprint of someone selling the refined iron sword, Xiao Han hurriedly clicked in.

"Mortal-level fourth-grade weapon building blueprints, I want to change the blueprints of level 4 houses, this guy hasn't woken up from a dream yet!"

With just one glance, Xiao Han knew that this human race called Song Shaojun could not get what he wanted, and the price was not at the same level at all, no wonder it had been hanging on it for so long.

However, he has the blueprints of the level 5 house construction of the goblin clan, although he will lose a lot if he changes this thing, and it seems that Song Shaojun, who only has a level 3 village, should not be able to make up the difference.

However, this drawing can be copied indefinitely, and he is not a loss, and he is still sold to the Terrans, so he should be regarded as a good person.

After thinking for a while, Xiao Han directly tapped and said, "A copy of the construction drawings of the level 5 goblin clan's dwellings, exchange for your refined iron sword blueprints." ”

After posting this sentence, Xiao Han also sent a screenshot of the Handao dwellings by the way, on which there happened to be three level 5 dwellings that had been built.

After waiting for less than five minutes, two words suddenly popped up under his message.

"Don't change!"
