There is a large garden outside the palace tree, as well as a large spacious meadow, Zhang Tie found an open place, stretched out his hand, and the blood sacrifice furnace contained in the space equipment of the Xuanwu Secret Library of the Blood Soul Temple that he carried with him was released by Zhang Tie, a statue more than thirty meters high, the upper body is humanoid, the lower body is snake-shaped, the whole body is like copper, and the lower body is still wrapped in a huge furnace The statue appeared on the lawn outside the palace tree.

It is common sense that all the space equipment cannot be used superimposed, and one space equipment cannot be put into another space equipment, but the Black Iron Fort does not have this restriction, here, Zhang Tie can freely enter and exit the Black Iron Fort at any time with the space equipment with him.

From this point of view, Zhang Tie felt that the Black Iron Fort was no longer a simple space equipment, but a special space.

The idol, the altar, and the furnace, these three big guys are completely connected together - at least in Zhang Tie's eyes, at this moment, he has completely regarded this idol as a big machine.

In the ruins of the temple, Zhang Tie had completely figured out the use of this blood sacrifice furnace and some special mechanisms hidden on the blood sacrifice furnace, and when he left the temple, this idol was naturally taken away by Zhang Tie.

Zhang Tie, the blood sacrifice furnace under the statue, first thought that it was the same as the Chaos Pool, and there would be nothing left after the blood sacrifice demon clan was incinerated, but in the back, after thoroughly studying this blood sacrifice furnace, Zhang Tie found that just behind the base of the blood sacrifice furnace, there was a secret grid, and inside that dark grid was a space with dozens of cubic meters. The role of that space is quite a place to store boiler ash.

Creatures incinerated by blood sacrifices. In the end, there will be something left, and that thing is not ashes. It's a dark purple one, something that is very difficult to distinguish and very difficult to tell, and a demon throws it in, and the kind of ash that can be left in the end may be a little more.

Heller said that it was the first impurities and raw materials of life, and this impurities and raw materials could not be found anywhere except what the Blood Sacrifice Furnace could provide, and the effect of this impurities and raw materials. But it may be the highest and most special fertilizer that human beings can get, and it is a great tonic for all plants.

The dark compartment of the Blood Sacrifice Furnace was now filled with two-thirds of this dark purple dust-like thing.

Hearing that this thing has a special effect on plants, when leaving the ruins of the temple, driven by great curiosity, Zhang Tie personally shoveled a little bit of that thing from the dark compartment of the Blood Sacrifice Furnace as fertilizer, and sold it under the two plane trees outside the palace tree.

After Aziz and the others went to bring the demon knights out, they took out the blood sacrifice furnace. Zhang Tie's heart moved, and when he remembered it, he went with Heller to see the two sycamore trees.

Outside the palace tree, there is a corridor consisting of two rows of plane trees, and there are hundreds of plane trees in that corridor. Zhang Tie just chose two ordinary plane trees at random, buried the fertilizer, and then walked in front of the plane tree corridor at this time. Zhang Tie suddenly discovered the two sycamore trees that he had randomly sprinkled with two handfuls of mysterious fertilizer.

The two plane trees, which were no different from other trees, were taller and more leafy than the plane trees around them at this time. The growth is very gratifying, and even more bizarre. The edges of the leaves of the two sycamore trees showed a strange circle of bright purple, so that the two sycamore trees suddenly showed a very obvious difference from the surrounding plane trees, as if standing out from the crowd.

"Ah, have these two sycamore trees mutated?" Zhang Tie was also taken aback when he saw the two sycamore trees, but he didn't expect that he grabbed two handfuls of that kind of ash-like thing at random and sprinkled them at the beginning, and in just a few months, these two sycamore trees had become so different.

"It's not that it's mutated, the variety of the plane tree hasn't changed, but it's growing too well, it's better than you can imagine!"

"Then why are the leaves of these two family plane trees different from other plane trees!"

"This is the change that these two sycamore trees have absorbed those nutrients and fertilizers, this change is that the castle lord sprinkled too much fertilizer at that time, and the second is that after their leaves change color, in the process of photosynthesis, they will produce something that other sycamore trees do not have, making these two trees healthier and more special, just like people, but the level of substances secreted by glands in different human bodies varies greatly, and the substances secreted by human glands, It also directly participates in and affects the various physiological activities of human beings and the level of existence of life, and the same is true for plants! Heller explains.

"Doesn't that mean that if you sprinkle those fertilizers on other plants, the growth of other plants will be very good, very healthy, and the species of the plants will not change, but the state of storage will become better!"

"Yes!" Heller nodded.

Zhang Tie laughed, "It turns out that after the blood sacrifice, you can also get the best farming fertilizer, this is really an unexpected joy!" ”

"If the castle lord wants to use this kind of thing to farm, it is really a waste, this kind of thing can be used for more advanced things!"

"Something more advanced?"

"For example, some special medicinal herbs, or high-grade tea leaves or the like, does the castle lord remember the last time he went back to Cui Li's hometown Longpan Mountain, he got some tea seeds and returned to the Black Iron Castle?"

"Remember!" Zhang Tie nodded.

After owning the Black Iron Castle, every time he went, Zhang Tie was accustomed to storing the new plant varieties that he could obtain, no matter how high or low, to the Black Iron Castle, and the last time he returned to Cui Li's hometown, he easily got some tea seeds at Cui Li's house and threw them into the Black Iron Fort.

"Those tea seeds were originally just high-quality tea produced on Panlong Mountain in Yongzhou, not how expensive, after the castle lord brought them to the Black Iron Castle, I have let those tea leaves complete an evolutionary mutation, the evolved mutated tea, the quality is even more unique, if the castle lord brings those tea seeds outside, and uses these special fertilizers to cultivate, this new tea is definitely unique in Taixia!"

Heller's words made Zhang Tiedu stunned for a moment, he didn't think that Heller actually made a new tea in the Black Iron Castle silently.

Tea, which is one of the most important commodities and daily necessities in Taixia, whether it is the Chinese people in Taixia or the wealthy people in other subcontinents, all regard drinking tea as one of the most elegant enjoyments, and the tea trade is a big gold mine......

I remember when I was in Black Flame City, the dead fat man of Barry made a few broken tea leaves, everyone was like a baby, at that time in the Weiyi Subcontinent, from the elders of Huaiyuan Hall to the nouveau riche in Black Flame City, they were all fans of tea.

Tea leaves like Yechun in Taixia, even if the elders of Huaiyuan Hall get it, they will treat it as a treasure and drink it sparingly.

Zhang Tie was still digesting the information in Heller's words, and the three of Aziz had already pushed the demon knights who were captured by him out......

Seeing the strange scenery in the Black Iron Castle, the few Black Iron Knights who were thrown into the dungeon of the Black Iron Castle after being knocked unconscious by Zhang Tie and did not see the light of day were all shocked, and some even looked sluggish, completely unable to imagine why they were here and what kind of place this was.

The colorful clouds and mist in the sky of the Black Iron Castle, the strange scenery of the Sacred Mountain, and the palace tree and the Blood Sacrifice Furnace in front of them were completely beyond their imagination.

Anyway, these guys are about to turn into fertilizer, and Zhang Tie doesn't care what these people saw before they died.

It's just that Heller's words moved Zhang Tie's heart, and he felt that those inconspicuous fertilizers could be of great use after returning to the ground this time......

……

There are a total of six black iron knights of the demon clan who were pushed by Aziz in a cart, and this is what Zhang Tie has gained in the past month or so.

These guys all have prohibitions, those prohibitions are made by Edward, and the same prohibitions can be used on the earth knights to make the earth knights like ragdoll toys at the mercy of others, not to mention the few black iron knights in front of them, the ban on the upper body, that is, it suddenly becomes fish on the board.

Most of those knights didn't react to what it was when they saw the Blood Sacrifice Furnace, only one of the Black Iron Knights, the guy who was stunned by Zhang Tie with space equipment on his body, as soon as he saw the Blood Sacrifice Furnace, a look of fear appeared in his eyes, and then he writhed excitedly, as if he already knew what kind of fate awaited him......
