Agreement? The agreement with Heller? Zhang Tie thought about it in his mind, then patted his forehead with a little embarrassment, and looked at Heller apologetically, "I was really negligent about the basic energy in space during this period, but I do There is no good chance to pour things into the Black Iron Fort. You know, the environment where I live, once someone discovers that I have this special ability, I might be pulled to slice it, so I have to be careful!"

"I understand the environment and the cautious attitude of Lord Fortress Lord. Regarding how to increase the basic energy reserve of the Black Iron Fort, I have a suggestion!"

"What advice?"

"I know that Lord Fortress came in for the two newly grown fruits on the Manshushahua Karma Myriad Fruit Treasure Tree!" Heller smiled, "This question, you can wait until the Fort Lord finishes those two fruits. talk!"

Zhang Tie didn't expect Heller to be so "compassionate". Hearing what Heller said, and looking at the small tree in front of him, Zhang Tie nodded, "Okay, I'll talk about it after I finish eating the fruit!"

The Black Iron Fort at this moment has indeed changed. The two-story wooden house with an area of ​​210 square meters previously ordered in Black Flame City originally had no time for Zhang Tie to assemble it, but at this moment, that building The houses have been standing neatly in front of Zhang Tie, and several assembled houses have been surrounded by a circle of high fences with wooden planks. Small trees are in the yard enclosed by the fence and houses.

The terrain in the yard seems to have been modified by Heller. The place where the small tree is located is obviously nearly two meters higher than the surrounding area, forming a huge and regular altar-like mound. Around the place where the small tree is located, It is a circle of white stone steps.

I have to say that after Heller's transformation, everything in this space is indeed more comfortable, and it seems to have a pleasing feeling.

"From now on, for all the creatures in this space, only Lord Fortress can step on these steps close to the Manshushahua Karma Tree!" Heller, who was walking with Zhang Tie, stopped in front of the steps. Stepped, explained next to him.

Zhang Tie nodded in satisfaction, then walked up.

The small tree is also growing. Zhang Tie feels that this small tree seems to be a little more lush than last time. Every time you come, you only need to see the mature ones hanging on the small trees, and some immature ones. Planting fruits, Zhang Tie's mood is very good.

One of the no-leakage fruits has matured and is hanging on the tree. The second no-leakage fruit will mature three days later. Knowing that the no-leakage fruit has the function of a spare blood bag in an emergency, it can save your life, so there is no leakage these days Guo Zhang Tie didn't even eat, but stayed on the tree.

In addition to the fruit without leakage, there is also a fruit of iron embryo, a fruit of soul catastrophe, and fruit of redemption.

Zhang Tie first glanced at the dark, lacquered, hexagonal shape.

——The Soul Tribulation Fruit has matured. To use, just take it directly after picking. Note that the fruit cannot be taken away from the Black Iron Fort. Twelve hours after being picked, the energy and vitality in the fruit will gradually be lost.

When putting his spiritual power into this soul catastrophe fruit, three sea snakes and the shadow of the iron stone beach appeared in Zhang Tie's mind.

Zhang Tie laughed loudly. After killing the three sea snakes, there really was a scene of the sea in the soul of the soul. This time, he had a place to practice water.

In the middle of the small tree, except for the redemption fruit that gave birth to the power of the golden unicorn, it was not yet mature, beside the fruit, another heart-shaped fruit was already hanging there.

——The fruit of salvation——The gratitude of the sand scales, has matured, the method of use, eat directly after picking. Note that the fruit cannot be taken away from the Black Iron Fort. Twelve hours after being picked, the energy and vitality in the fruit will gradually be lost.

——This fruit can increase the body's cold resistance in water and cold environments by 1%, and the body's sensitivity to water flow by 1%.

Because fish breathe with their gills and humans breathe with their lungs, this fruit of salvation did not give Zhang Tie any abnormal underwater breathing ability. This is caused by the difference in physiological structure. After all, Zhang Tie It is impossible to become a monster with fish gills, but the two abilities provided to Zhang Tie on this fruit also shocked Zhang Tie.

Many fishes living in the water have super cold-resistant ability. In the book Zhang Tie read, it was recorded that some fishes were still alive and kicking in the water after being frozen for many days. Zhang Tie did not expect that the small sand scales were actually one of the hardy fish.

In addition to being unable to breathe in the water, one of the biggest factors that limit the length of a person’s activity in the water is that low-temperature seawater will cause a person to lose temperature quickly in the sea, and the human body will become stiff after losing temperature. Chills, confusion, and death due to symptoms such as cardiopulmonary failure.

A silver coin, one percent increase in cold resistance, and one percent sensitivity to water flow, Zhang Tie really felt that he had earned it.

Money is priceless, life is priceless, and the ability brought by life is priceless!

With a complicated mood, Zhang Tie picked the fruit of salvation and ate it in his mouth. As soon as the fruit was bitten in the mouth, the juice of the fruit slipped into the stomach and turned into a warm stream towards Zhang Tie. The skin and subcutaneous tissue of the whole body spread out, and it was absorbed by Zhang Tie in just a few minutes.

After eating the fruit of redemption, Zhang Tie picked the soul catastrophe fruit and ate it again. After eating this soul catastrophe fruit, Zhang Tie closed his eyes and felt it, knowing the magical arch in the sea, as expected. There was another six-pointed star, and this six-pointed star was already active, which meant that Zhang Tie could enter the realm of Soul Tribulation inside at any time.

Because Heller was still waiting for him, and there was something to discuss with him, Zhang Tie didn't go in again, anyway, there will be time in the future.

Just as Zhang Tie was about to leave the small tree, he saw the iron fetus fruit on the small tree. He didn't know why. At this time, he felt that the color of the iron fetus fruit seemed a little different than when he came last time. So Zhang Tie checked it smoothly.

Hey, it's strange. Zhang Tie felt that the maturity of this iron fetus was only about one-third when he came last time. How come the maturity of this iron fetus was nearly one-half when he came this time?

Is it because you read it wrong? Probably not! Ever since his mental power skyrocketed, Zhang Tie’s memory is getting better and better. Zhang Tie doesn’t believe that he will remember wrong. He hasn’t had time to practice the bear-back iron fetus skills in the past few days, and he has not been beaten by anyone. How can the degree increase.

Ask Heller!

...

Heller has been waiting for Zhang Tie to come down outside the steps under the small tree.

"Heller, what is your suggestion on how to increase the basic energy reserve of the Black Iron Fort?" Zhang Tie asked straightforwardly.

"My suggestion is to ask Lord Fortress to seize the opportunities around you. In the past few days, you have many opportunities and time to increase the basic energy reserve of the Black Iron Fort. But I have not seen Lord Fortress take any action. !"

"Do you mean the rocks in the sea? I am now familiar with the water. I will take action when I can dive deep enough in two days..." Zhang Tie thought about it and understood According to Heller, the environment in the sea is indeed good, just like mines. If you choose a place with few people and make it more concealed, you should be able to use the basic space storage function of the Black Iron Fort you just mastered. It’s right to keep things inside without being discovered.

"I'm very happy that Lord Castle can think of rocks in the sea, but this is not what I want to say..."

"what is that?"

"Don’t you expect the Lord of the Castle?" Heller's expression was slightly agitated, "When you are in the sea, there is seawater everywhere around you. You only need to use the space storage function of the Black Iron Fort to open and stabilize. Living in the space channel on both hands, the sea water can be sucked from the sea to the Chaos Pool of the Black Iron Fort! Is there a way to increase the basic energy reserve of the Black Iron Fort more easily than this?"

Zhang Tie was stunned, his brain banged, yeah, why didn't he expect that as long as he dived into the sea, who could find that the water in the sea was a little bit less? Moreover, since I can use the space storage function of the Black Iron Fort to **** seawater into the Black Iron Fort, then, in turn, can I also **** the air of the Black Iron Fort to the outside through the space door?

"Of course you can. Didn’t the Lord Lord have tried to move the water in the Black Iron Fort into the outside cup? You only need to lock any space in the Black Iron Fort, and you can also remove the air in that space. Transfer it out! If you are in the water, it is estimated that you can use your ability to breathe freely underwater after only a few tries."

Zhang Tie covered his mouth with one hand, and asked in a dull voice, "You mean I can transfer the air in the Black Iron Fort to my hand as long as I use this action in the water. , And then I can breathe freely through my hands!"

"That's it!" Heller nodded, "This is also one of the uses of the space storage function of the Black Iron Fort, but there is a simpler way. If you want to breathe in the water, you You can try to directly send the air transferred through the space door of the Black Iron Fort into your mouth!"

Upon hearing this, Zhang Tie almost jumped up. It is worthy of the space storage function of the Black Iron Fort. This function is simply fantastic and so flexible. It is simply an oxygen tank to carry around. Compared with the oxygen tank, The Black Iron Fort is invisible, and the air in the Black Iron Fort is definitely 1,000 times fresher than the oxygen tank.

Zhang Tie almost wanted to go out and try it now, but before he left, he still had a question, "By the way, when I came last time, that iron fetal fruit seems to have only matured one-third, how come these days? Will its maturity increase?"

"During your diving, the sea pressure of different water depths is constantly changing and acting on your body. This process is the same as if your body is hit by someone or hitting something. The only difference between the two is The force you receive underwater is continuous and uninterrupted, but you can adjust the amount of force the sea water exerts on you by adjusting the depth of the dive, as long as the force exerted on you can fluctuate. This kind of power can promote the maturation of the iron fetus fruit. In this process, you can regard the sea as an immobile hammer. You..."

Heller has not finished speaking, Zhang Tie has disappeared...
