Todd put the keel on Alfonso's body, then asked him to put on the metal armor and begin experimenting with the effects of the new equipment.

The latter looked at the parasite limbs wriggling in the cold wind, and first tried to use the keel to absorb the cold of the outside environment according to Todd's instructions.

In just a dozen seconds, Alfonso's metal armor had formed a thick layer of frost, and it looked like he had put on a layer of 'ice armor' on the outermost.

Todd stretched out his hand and knocked on Alfonso's ice armor, and the hardness and protection made him nod happily: "The transformed keel can condense cold air to form a new layer of protection on the surface of the armor, plus the user's own ability, the keel's own defense and metal armor, the inheritor is equivalent to having four layers of protection ability, unless it is a large siege weapon and gunpowder weapon, it is difficult for something to penetrate these protections." ”

Alfonso moved his legs and feet, and said with satisfaction: "The sluggishness of the previous action has disappeared, no matter what kind of action, it is effortless to do now." ”

Todd also asked Alfonso to try out the keel's regenerative transformation and the honeycomb's infrasonic communication abilities.

The former can elongate, deform, and entrench the keel in various shapes, which can be used not only as an attack mode, but also as a defensive mode, and even into a marching mode for climbing cliffs.

As for the infrasonic communication hive, on the one hand, the communication distance is extended from the original 50 meters to 1.8 kilometers, and on the other hand, the silent transmission of sound waves is also realized, which effectively avoids the detection of the enemy. The only drawback is that infrasound waves can cause damage to the human body after all, if the vibration frequency and power of the hive are not properly controlled, it will cause nausea, dizziness, weakness of limbs, and even shock in severe cases.

Leaving the upgraded keel to the Guards, Todd returned to his small building first.

Rachel was busy packing up her utensils when she saw Todd return and said, "You're back just in time." ”

Todd was a little surprised: "What's the matter?"

"Anyway, don't ask so much, you change into tyrant mode first. ”

Although Todd was confused, he evolved into a monster form according to Richel.

Rachel looked at the large mutant in front of him whose head could touch the ceiling, and said thoughtfully, "Sure enough, it's the same as I thought......"

Todd had a puzzled look on his face.

Rachel raised her hand and reached for Todd's head, asking him, "Don't you think you're taller and bigger now than you were when you first came out of the Dark Door?"

Todd gestured to his measurements, and it was only then that he realized that Rachel was right. The original monster form was only two meters tall, but now it is more than three meters, and its size is much larger than in the past.

Rachel took a closer look at Todd's monster form, and finally couldn't hold back, and laughed out loud: "This way, you look like a large lizard clad in steel." ”

Todd's heart moved, as if he had thought of something, but in the blink of an eye he couldn't remember what it was.

Seeing Todd return to his original state, Rachel asked, "Why do you think the evolutionary form has changed?"

Todd scratched his head: "I don't know, I didn't notice this before, maybe it has something to do with the long-term exposure to the Tyrant virus?"

Rachel gave him a roll of the eyes: "Listen to what you said, I don't know, I didn't pay attention, didn't you always care about your own strength and ability?"

Todd was a little confused, he wasn't sure why Raicher was bringing up the topic.

"On the battlefield, the first task of the non-commissioned officers is to protect the survival of the commander. It is indeed the responsibility of the commander to distribute good equipment to the soldiers. But the Lord himself should also have the ability to protect himself. Rachel crossed his arms over his chest and looked Todd up and down: "A wise commander will put on the strongest armor, take the sharpest weapons, and ride the fastest warhorse, rather than pin his life on the protection of others." ”

Todd kind of understood what Reichel was trying to say, "You want me to enhance my ability to protect myself?"

"Your Majesty, my Majesty, look at what has happened to you over the years!" Richer looked a little annoyed, "The attack of the Presbyterian Church, the trials of the Shadow Nation, the gladiatorial arena of Ulster...... I bet there is no other king on the entire continent whose life is more 'colorful' than yours!"

"You're smart and cute sometimes, but you're also silly and sad sometimes. "Richel's poisonous tongue skills made Todd a little overwhelmed.

The latter simply signaled to Richer that he had something to say.

Rachel pointed to Todd's body and said to him, "One is the strengthening of the tyrant form, and we can't find the reason for this at the moment, so we can only put it aside for a while, and the other is the way to protect ourselves...... If I'm not mistaken, you already have more than a dozen abilities in you, right?"

Todd gave the other party an accurate answer: "To be precise, it should be thirteen." ”

"I remember you told me that although the Tyrant Successor (the Successor who has been transformed by the Tyrant Virus) can accept more than ten abilities, the strength of the ability decreases as the number of Xenos in the body increases?"

"That's right, due to the upper limit of the organism's own immunity, the tyrant heir has a certain limit on the total amount of abnormal bacteria that can be accommodated. For example, if I have 1,000 milliliters of bacteria in my body, and I have 10 types of bacteria in my body, then there are only 100 milliliters of each bacteria, and if I have five bacteria in my body, the number of each bacteria is about 200 milliliters, and the power of natural bacteria is twice as high. ”

Rachel nodded, and then pointed to the bottles and jars on the table: "Through long-term experiments, hasn't the Twilight Academy developed a potion that can eliminate the designated abnormal bacteria in the body?"

Todd's eyes lit up, "You mean ......?"

"What I'm trying to say is that you can eliminate the abnormal bacteria in your body that you can't use for a short time first, leaving the usual abnormal bacteria in the body. This way, whether it's normal or evolved, when you use an ability, it's an effective way to increase the power of the ability. And if you need a certain ability in the future, you can find it in the ability library and inject it into your body?"

Todd was inspired by Richel's words, and he began to think about the state of his abilities in his body.

It seems that there are a lot of abilities in your body, but the effect of using them is greatly reduced, and if you can really adjust the available abilities in your body in a timely manner according to the changes in the situation and the environment, this is definitely a good idea to get twice the result with half the effort.

With that in mind, Todd began to discuss his ability options with Rachel.

"Regeneration and Steel Skin are protective abilities and should be left behind. ”

Rachel nodded, "Haste can be used to quickly escape the battlefield, so it should stay." ”

Todd was a little embarrassed: "The word escape is too harsh. ”

"As a king, do you still want to run on a rampage on the battlefield like a gladiator?!"

Todd shrugged, "Well, Hawkeye's ability can't be eliminated because I need it for research." ”

"Body change and soul link can't be removed, these are two abilities that are often used. Rachel counted on his fingers: "There are still clairvoyance, night vision, weakness, underwater breathing, pain suppression, and soil control......

"It's true that these abilities are used less frequently, but they are useful...... Todd is now like a tangled shopaholic, who can't hold anything on his body, but he's reluctant to discard them. After all, these abilities have been following him for quite some time.

"For now, none of these abilities are of much use. ”

Rachel's words gave Todd a bit of a headache, and he said, "If you take these abilities away like this, there's going to be a problem." ”

"What's the problem?"

"I won't have any offensive abilities on me, just defensive and morphing abilities. ”

Rachel pondered for a moment, then nodded in agreement, "You're right, you do need some means of attack when you encounter an enemy, let me think about it." The weakening ability only works in melee combat, which is risky to use in combat, the ability to control the land is slow to activate, and most of the land in the north is frozen ground, which is not conducive to the ability taking effect. These two abilities aren't a good fit to fight here. ”

Todd suggested, "What about the freezing ability? In this cold environment, the ability can be more powerful. ”

Rachel nodded in agreement with Todd.

After deciding how many abilities to increase or decrease, Todd began using the Directed Bacteriophage concocted by Twilight Academy, removing the less useful abilities from his body one by one, and infusing him with Frozen Bacterial Liquid.

At this point, Todd's abilities have been reduced to seven: Regeneration, Metalskin, Speed, Eagle Eye, Form Change, Soul Link, and Frozen.
