Qi Yuan rubbed his eyebrows with a headache. If Seraph had told him that it could communicate with the Tree of Annihilation, this problem had been solved.

But now, it is probably impossible to communicate with them again.

Feng Gan will definitely not let himself go to his laboratory again.

"Do you know what they want to eat?" Qi Yuan asked.

"Eat the Star Energy Stone!" Seraph replied.

Star energy stone!

A light flashed in Qi Yuan's mind, vaguely capturing something.

In the flesh and blood culture medium of the Annihilation Tree, there is no trace of energy from the star energy stone. This is obviously not a normal phenomenon. The insects and beasts above the fourth level will have more or less energy from the body of the star energy stone, but in the culture medium that has swallowed more than ten powerful insects and beasts, there is no trace of energy from the star energy stone!

Moreover, there is no star energy stone energy in the Annihilation Tree!

Where did those star energy stone energy go?

Even if it is scattered, it is impossible to scatter so thoroughly.

Therefore, they were absorbed by the Annihilation Tree!

The reason why the growth of the Annihilation Tree requires powerful insects and beasts above the fourth level is because they have astral energy stone energy in their bodies, and it requires more than just flesh and blood!

When Feng Gan was studying this project, he was just an ordinary second-level researcher, so he could not waste the precious star energy stones on the tree of Annihilation. Moreover, the tree of Annihilation swallowed flesh and blood made him ignore this point, which led to those Annihilation trees not growing up.

After thinking through the reasons, Qi Yuan went to the twelfth floor of the prison again, sampled the root system of the tree of Annihilation that was infiltrated into the flesh and blood, and at the same time packed and brought back a few corpses of fourth-level insect beasts, and then began to make flesh and blood culture medium.

Qi Yuan spent a whole day to complete the flesh and blood culture medium, and then began to cultivate a new tree of annihilation.

The cultivation of the Annihilation Tree was very smooth. Under the nourishment of the flesh and blood culture medium, the seedlings of Annihilation Book grew their first tender leaves in just half a day.

An ordinary serious plant cannot grow so fast, but for the Annihilation tree, there is only one condition that limits its growth, that is, whether the energy of flesh and star energy stone is sufficient.

Qi Yuan monitored the energy of the star energy stone in the flesh and blood culture medium. As the seedlings of the Annihilation Tree sprouted, the energy of the star energy in it was quietly reduced.

Because of the characteristics of the energy of the star energy, it is difficult for ordinary instruments to monitor their changes, but in front of energy control and seraphic angels, there is no secret to any change in the energy energy of the star energy.

When the seedlings of Annihilation grow to the thickness of their fingers and grow a third tender leaf, the flesh and blood in the flesh culture medium has only decreased by less than 10%, but the energy of the star energy has been exhausted.

The growth of the seedlings of Annihilation also stagnated.

Qi Yuan thought for a while and did not immediately inject the energy of the star energy stone into it. Instead, he took out a star energy stone from the warehouse and slowly implanted it with the rhizomes of the seedlings of the Annihilation Tree and slowly implanted it into the flesh and blood culture medium.

This scene made Seraphite drool.

Want to eat so much!

With the implantation of the star energy stone, the root system that was sinking into the flesh and blood culture medium slowly entangled, tightly binding the entire star energy stone, and the annihilation tree that had originally stopped growing continued to grow.

However, even with the energy provided by the star energy stone, the tree of Annihilation is growing very slowly. It took it three full hours to grow a fourth tender leaf.

The enclosed star energy stone has only shrunk by about 5%.

Compared to absorbing the energy of the star energy stones in the flesh and blood, the tree of Annihilation has significantly slower to absorb the solid star energy stones.

Is this too small, indigestion?

Qi Yuan tried to directly merge a wisp of star energy into the body of the Annihilation Tree, but unexpectedly failed. The trunks and leaves of the Annihilation Tree could not absorb the energy of the Star Energy Stone.

Afterwards, Qi Yuan tried to incorporate a wisp of star energy into the culture medium and merge it with flesh and blood.

As a result, the root system of the Annihilation Tree, which originally wrapped in the star energy stone, grew wildly. They began to swallow the energy of the Anihilation Tree that fused with the flesh and blood in large mouths. At the same time, the growth of the Annihilation Tree gradually accelerated. In less than a minute, the seedlings of the Annihilation Tree became thicker, and the bright red tender leaves also grew eight consecutively.

"It's still a soft but hard!"

Qi Yuan laughed, as if he saw that the door leading to the fourth level had been opened to him.

After understanding the temper of the Annihilation Tree, Qi Yuan began to increase the energy feeding of the star energy stone. When it absorbed nearly ten kilograms of the Anihilation Tree's seedlings were no longer smaller than the seedlings in Fengqian Laboratory.

Although the tree of Annihilation grows very fast, the consumption of star energy stones is also shocking. Qi Yuan estimated it slightly and wanted to ripen the tree of Annihilation quickly, it would probably take nearly one ton of star energy stones.

If I hadn't made a fortune on the statue of the headless giant, I would probably have invested all my current wealth and could not have ripened a few trees of annihilation.

In addition to star energy stones, the flesh and blood in the culture medium is also consumed very much. While absorbing the energy of the star energy stone, most of the flesh and blood in the culture medium are also swallowed up. If this continues, it will soon come to an end.

The corpse of the fourth-level insect beast is not a cabbage. Even if the butcher in the prison is willing to help, he will not be able to consume the prisoners in the prison without restraint.

After pondering for a while, Qi Yuan quickly had a replacement, which was to replace the insects and beasts below the fourth level.

In Feng Qian's paper, he proposed that only the blood and flesh of insects and beasts above the fourth level were used to make culture media because there was no star energy stone energy in the insects and beasts below the fourth level, and now he could provide additional star energy, so there was no difference between insects and beasts above the fourth level and below the fourth level.

If it can be successfully replaced, the cultivation cost of the Annihilation Tree will undoubtedly drop a lot.

In the Heigang Shelter, the corpses of insects and beasts above the fourth level are relatively precious, but the corpses of insects and beasts below the fourth level are cheap. Qi Yuan effortlessly brought in a large number of corpses of third-level insects and beasts.

Naturally, Qi Yuan’s large number of corpses of third-level insect beasts cannot be concealed by others. Except for Tan Qiu who vaguely guessed some inside stories, the rest of the people felt very strange, why did Qi Yuan want so many stars and stones?

Feng Qian vaguely felt that Qi Yuan suddenly wanted so many star energy stones, which was probably related to entering his laboratory. However, because Qi Yuan bought all the corpses of third-level insect beasts, he did not think of the Tree of Annihilation at all.

The cultivation of seedlings of Annihilation Tree requires at least a fourth-level insect and beast to make flesh and blood culture medium. This is the conclusion he has drawn from many experiments, so he believes it without doubt.

However, Feng Qian still felt a faint uneasy in his heart.

Every move before Qi Yuan would bring an "surprise" to the enemy. After facing the "surprise" from Qi Yuan several times, Feng Gan was really unwilling to be suddenly hit by Qi Yuan in the face without knowing it.

In order to relieve the uneasiness in his heart, Feng Gan even checked the experimental projects under Qi Yuan's name and found that Qi Yuan had not applied for a new project recently, so he felt a little relieved.

Although Qi Yuan already has a small family background, those projects that can bring surprises require a lot of supplies, which are not something Qi Yuan can support.

Amid all kinds of doubts and speculations, Qi Yuan spent half a month consuming nearly a ton of star energy stones before finally urging the tree of Annihilation to mature.

The tree of Annihilation that has just entered the maturity is as powerful as the tree of Annihilation in the prison, but it has formed a complete tree of Annihilation. Annihilation is a symbol of the maturity of the tree of Annihilation. After having the tree of Annihilation, even if you no longer feed the energy of the star energy stone, the tree of Annihilation can absorb other energy, convert it into the power of annihilation, and slowly grow itself.

Perhaps because of artificial ripening and the growth time is too short, the tree of annihilation cultivated by Qi Yuan did not show the characteristics of wisdom, and everything was acted according to instinct.

This has reduced many troubles from Qi Yuan. At least there is no need to worry that it has strong aggressiveness like the Annihilation Tree in the prison. Although the Annihilation Tree has condensed the Annihilation Tree Heart, it has just entered maturity, and Seraphim can completely control it.

Qi Yuan originally tried to use mechanical control of the tree of Annihilation, but it was useless and could only give up.

With the help of Seraph, Qi Yuan used energy control to draw two balls of annihilation power from the Annihilation Tree, made it into the energy core, and then began to make annihilation energy weapon.

In order to fully demonstrate the power of annihilation energy, Qi Yuan made two weapons at once, one was an energy sword for melee combat and the other was an energy gun for long-range snipers.

The two annihilation energy weapons can only be considered average for flesh and blood living bodies. Compared with mechanical weapons of the same level, they have no obvious advantages. However, the killing of mechanical bodies makes Qi Yuan even scared.

After completing the paper, Qi Yuan sent a message to Tan Qiu and called her to his laboratory.

After Tan Qiu came to the laboratory, he saw the annihilation tree growing in the flesh and blood culture medium, with a height of more than three meters and looking lush.

"Is this the research result?"

Tan Qiu looked at the tree of annihilation and felt the power of annihilation in its body. Although he was a little surprised, he was not too surprised.

Fenggan has already recorded successfully cultivating the tree of annihilation, although it is only a seedling, and has not condensed the powerful power of annihilation.

Although Qi Yuan's Annihilation Tree is mature and full of annihilation power, it is at most just a fourth-level project, far from reaching the level that can impact the Leader's Medal.

"It's just one of the results!" Qi Yuan said calmly.

Tan Qiu raised his eyebrows. After Feng Gan successfully cultivated the seedlings of Annihilation that year, he wasted a lot of time on the project to cultivate them and all failed in the end.

Qi Yuan was able to complete Feng Gan's failed project in such a short time, and the slap of this slap was already slapped Feng Gan in the face.

The meaning of Qi Yuan's words seems to be not the main result. Could it be that he has really successfully cracked the secret of the power of annihilation and created a weapon of the power of annihilation?

In Tan Qiu's surprised gaze, Qi Yuan took out the weapon made with the power of annihilation.

It was a sword hilt about twenty centimeters long.

Qi Yuan handed the hilt of the sword to Tan Qiu and said with a smile:

"This is the real result!"

Tan Qiu took the hilt and found that the hilt was light and had a special touch. It didn't look like the usual metal, and it looked like wood. But Tan Qiu was sure that it was not wood, because no known wood could carry the strength of energy weapons. Even the tree of Annihilation itself would quickly decay after it left the trunk.

Only various high-strength special alloys can etch the energy matrix and carry the terrifying strength of energy weapons.

"What metal is this?" Tan Qiu asked.

"The only advantage of a brand new alloy is that it can carry the erosion of the power of annihilation." Qi Yuan said.

Tan Qiu activated the energy sword, and a scarlet and blood-red energy sword blade extended out.

Feeling the powerful annihilation power in the sword blade, even though he was mentally prepared, Tan Qiu couldn't help but change his face slightly.

Qi Yuan really cracked the secret of the power of annihilation!

He not only made metal that can carry the power of annihilation, but also made a supporting energy matrix.

To a certain extent, the energy sword of the power of annihilation in one's own hands is not a single result, but multiple experimental results and combinations. Whether it is the rapid ripening of the tree of annihilation, the special alloy that can carry the power of annihilation, and the energy matrix that matches it, you can set up a separate research project.

These projects are divided into several three-level and four-level projects, but once they are all combined, this is a great invention that is enough to sprint for the Leader's Medal.

Qi Yuan took a piece of four-level alloy and placed them on the experimental table.

"You can try the power of this sword."

Tan Qiu held the hilt of the sword and gently waved the sword man. He saw that the sword blade condensed from the power of annihilation was like a knife cutting tofu, and easily used all two pieces of this fourth-level alloy.

Tan Qiu picked up a piece of cut alloy and saw that the section was as smooth as a mirror, which showed the sharpness of the sword blade.

"This seems to be the fourth-level alloy used for mechanical creation in the mechanical royal court." Tan Qiu said.
