In the following days, Lin Zeng experienced almost no stopping pain.

On the second dip, Miss Lannie returned.

She brought Lin Zeng the leyline fruits produced by those multiplayer plant playgrounds in cities other than Qinghe City.

Enough Lin Zeng to soak ten times.

Lin Zeng is completely using masochistic means to complete physical reinforcement again and again.

Each time, he shortened the soaking interval by half a day to the limit of what his body could tolerate.

Each shortening brought him more intense pain than the last.

If it was the first time, it was still the pain of pinprick skin, as the time of each soaking became shorter and shorter, the pain that tortured Lin Zeng seeped from the skin to the muscles, spread from the muscles to the internal organs, and then went all the way to the bone marrow.

And, after the time decreased, the time left for him to recover also decreased.

The pain of the last time has not gone away, and the pain of the second immersion has returned.

Sometimes, Lin Zeng can't help but miss the leisurely bathing time in the first half of the year, compared to it, it is simply the difference between hell and heaven.

In order to overcome this painful time, Lin Zeng spent a large amount of crystal source bodies to exchange a large number of inheritance materials in the database, and used the method of learning materials to alleviate this painful experience.

I don't know if the pain effect is too strong, Lin Zeng actually found that the efficiency of learning in this pain is a little higher than usual.

Although this method of learning is not a pleasant experience for him.

The only time he felt happy was when he rushed to the kitchen with a bottomless stomach after every bath, and Jiang Hua had prepared a mountain of food for him.

Mainly all kinds of meat, plant-based meat, animal meat, and solid rice noodles.

Because of the amount of food he eats, the consumption of the farm has increased dramatically, and many food forests have had to contact the cultivation base of Xenodu Company and ask someone to deliver it to him.

Jiang Hua himself is very busy, but he still finds time to prepare plenty of delicious food for him.

Lin Zeng was always gobbling up while watching Jiang Hua busy, taking out all kinds of food from various cooking tools such as ovens, rice cookers, pressure cookers, and earthen stoves.

At this moment, for Lin Zeng, it was full of a strong sense of happiness.

Jiang Hua is supporting Lin Zeng in her own way, and as a simple and happy breeding elf, Miss Lannie can't understand why her nurturer, Lin Zeng, would choose this way to carry out such a painful process of body strengthening.

It's easier and more sinless, but it's just a matter of taking a little more time.

She persuaded Lin Zeng, but Lin Zeng never wavered.

Miss Lannie could only collect as many leyline fruits as possible for him, plant more leyline root vines, and provide sufficient logistical support for Lin Zeng's strengthening path.

Planters are breeders' most trusted partners.

Although Miss Lannie has a strange personality and sometimes desperately develops her own personal hobbies, she is still a qualified breeding elf, and she will loyally guard Lin Zeng no matter what happens to her nurturer.

In fact, in addition to the unbearable physical pain, Lin Zeng's physical fitness actually ushered in the process of accelerated improvement in the baptism of severe pain.

As the system says, shortening the immersion time is actually not harmful to the body of the immersion person except for making the immersion person experience abnormal pain.

This drastic method can speed up Lin Zeng's physical strengthening speed up a lot.

According to the system's calculations, as long as Lin Zeng can maintain this soaking speed, he will be promoted to a four-star breeding apprentice in less than two months.

This goal became a carrot hanging in front of Lin Zeng, and for this, he faced the torture experience every two and a half days with amazing willpower.

Even, he accompanied Jiang Hua to a Berry Lawrence concert in the mood of suffering, and then ran to the city Xenomorph Farm and had a sweeping supper.

Lin Zeng, who entered the circular hell bath, did not have too much energy to pay attention to the changes in the outside world.

Two months passed in a flash, but he felt that life was like a year, as long as a century.

By the time he suddenly heard the system prompt, Lin Zeng didn't have too much excitement about it.

"The master of the space has been promoted to a four-star breeding apprentice. ”

"Upgrading the furnace, upgrading the internal functions of the furnace. ”

"Get a promotion lottery reward. ”

"Open the database of four-star breeding apprentices. ”

Unlike the tinkling rewards of the previous three apprentice promotions, this time the promotion process was very calm.

Lin once speculated that this reason had something to do with the fact that it was difficult for three stars to be promoted to four stars and that there was no threshold.

The previous three promotions required the completion of a difficult task, and the task rewards and promotion rewards were combined, so it seems that the rewards are very generous.

The main task of promoting four-star and five-star breeding apprentices is to strengthen the body.

Lin Zeng did not rush into the breeding space to check the changes that had occurred in the refining furnace and complete the lottery rewards, but after packing up, he went straight to the kitchen.

Anyway, there have been many promotions, and he is used to it, and now it is more important to eat.

Still swept once, and when Lin Zeng served the stomach with excessive demand, Jiang Hua also began to be busy with the design of his next milk fruit Qiangong stepping bed, and Lin Zeng entered the breeding space.

The last time it was promoted, the Ding furnace was increased from a single furnace body, just like a gourd shape.

Lin Zeng also guessed that this time he would be promoted, would he not add a round ball to the top again, and every time he was promoted in the future, a round ball would be added, and then his refining furnace would become a sugar gourd?

Thankfully, this speculation did not come true.

This kind of spicy-eyed shape is not an option after the refining furnace is upgraded.

The refining furnace does have an additional round furnace, and the three furnaces are completely detached, not connected together as before, but suspended in mid-air, taking the shape of an equilateral triangle. The three Ding furnaces meant that Lin Zeng's seed refining furnace had increased by four, making a total of twelve furnaces, and refining plant seeds at the same time could greatly relieve the pressure on him refining seeds.

After each promotion, four furnaces can be added, which seems to be the law of these two promotions, and I don't know if the promotions will continue to increase in the future.

Lin Zeng seemed to understand that it was not for nothing that those master-level breeders could supply the special seed supply of the entire planet by themselves.

After Lin Zeng checked the situation of the refining furnace, he planned to start drawing promotion rewards.

Advancing to the lottery is a very important channel for Lin Zeng to obtain special plant seeds from the Xenoworld.

Most of the prizes on the Reward Wheel are plant varieties that are impossible to find on Earth.

For example, milk fruits, bubble plants, weather plants, these plants, if Lin Zeng uses the native plants on the earth to refine and transform, they will not be able to see their functions at all.

When Lin Zeng indicated to the system that the lottery was starting, the projection of the prize of this lottery immediately appeared on the blank wall.
