The final gap in the defense line must be filled, but it was worth considering what defensive structure to build.
He now had two level 1 magic cores, a level 2 magic core with a Defensive Halo, and a level 3 magic core with an Amplification spell.
The level 2 magic core with a Defensive Halo had been scheduled by Thomas to be used to build the wall.
As long as he got enough magic cores, he would be able to complete it.
It seemed that there were not many things to choose from.
What was more powerful and could save magic cores?
Thomas kept flipping through the building blueprints in his mind, trying to find a building that suited his current needs.
Suddenly, he found something.
The War Tree.
The War Tree was a huge tree. It had intelligence and could swing its branches to fight the enemy.
Although the attack range was not far, it was enough to kill at close range.
Together with O'Neill and the other four melee warriors, it was enough to block the attacks of ordinary level 1 or level 2 dark creatures.
Moreover, the most important thing was that the War Tree could move.
He did not have enough materials at the moment, so they could build a War Tree in case of emergency. When he had enough cores, he could also move the War Tree to other places without wasting any materials. It was simply wonderful.
After making the decision, Thomas placed the remaining two level 1 magic cores and the level 3 magic cores on the ground. "Build the War Tree!"
The magic array rotated, and the magic runes lit up one by one. A small sapling grew out of the magic array.
The tree grew thicker and thicker, until it was as thick as a person.
[Level 1 War Tree discovered. Super Enhancement System triggered. Increasing...]
[Level 1 War Tree increased to Level 3 Ancient War Tree.]
[Level 3 Ancient War Tree: Level 3 defensive structure. It has life. It can heal itself during rest and grow on its own.]
[Attack Mode 1: Twig whipping. Use the twig whipping to entangle the enemy, controlling the enemy and suffocating the enemy to death. Attack range: 20 meters.]
[Attack Mode 2: Fruit throwing. The Ancient War Tree will produce an extremely hard fruit. The Ancient War Tree can throw the fruit to attack the enemy. Attack range: 200 meters.]
[Remark: Because the Level 3 magic core has an Amplification effect, the toughness of the branches has been doubled, and the weight of the fruit has been doubled.]
Looking at the long list of information in front of him, Thomas was overjoyed.
He knew that the War Tree would be very strong after two enhancements, but he did not expect it to become so strong.
The War Tree, which was originally only as thick as a man, now had a diameter of one meter and a height of seven to eight meters. It was a huge monster.
Moreover, there were branches as thick as a man's arm hidden in the huge crown of the tree. With these branches, Thomas did not believe that any dark creature could penetrate the defense of the Ancient War Tree.
What was even more surprising was that the Ancient War Tree actually had the ability to attack from afar.
Looking at the fruits that were the size of basketballs in the crown of the tree, Thomas felt that if he was directly hit by these things, even a level 2 dark creature would be smashed to death on the spot, right?
"Respected Sir Thomas, the Ancient War Tree Gertrude sends his regards to you." An old face appeared on the trunk of the war tree and spoke to Thomas in a muffled voice.
"Hello, Gertrude, let me see your ability!" Thomas said to Gertrude.
"Yes, Sir Thomas."
As Gertrude spoke, more than 20 vines that were as thick as a wrist stretched out from the tree crown and pulled forward.
In the blink of an eye, seven or eight deep ravines were drawn from the ground.
Then, Gertrude plucked three or four more fruits from the crown of the tree and threw them into the distance.
Three or four fruits instantly hit a small wooden house 150 meters away.
Boom!
The small wooden house was instantly smashed into pieces by the fruit the size of a basketball.
"So powerful." Thomas looked at the smashed small wooden house with excitement in his eyes.
The wooden house had been smashed into pieces. Even a level 2 dark creature could be killed in one hit, right?
"Oh right, Gertrude, how many of these fruits do you have? How much time do you need to recover?"
If there were not many fruits, this move could only be used as a trump card.
"I'm now a Level 3 Ancient War Tree. There are a total of 150 fruits. Every time I level up, there will be an additional 50 fruits. If I recover, it will take about 24 hours."
"Not bad. Although 150 is not that many, it is enough."
Thomas calculated in his heart and felt very satisfied.
"From now on, I will leave the defense of the West Camp to you. I will ask O'Neill and the others to cooperate with you. Do not let a dark creature pass through here."
"As you wish." Gertrude's tree crown made a rustling sound.
At this time, O'Neill and the others had finished eating.
Thomas called O'Neill over. "This is the Ancient War Tree, Gertrude. In the future, if there are dark creatures attacking, you will coordinate with Gertrude to guard the Western defense line. Also, you must arrange the guards at night. Don't be ambushed by the dark creatures."
Every night, the dark creatures would be the most active. They would attack the human camp in an organized manner. The defense at night became the most important thing.
"Don't worry, Sir Thomas. I will definitely guard the defensive line well. I will definitely not let a single dark creature pass through the defensive line," O'Neill said as he patted his chest.
"Okay." Thomas called Arya over to remind her again, and then he laid down in the Great Lighthouse to rest.
Lying on the ground in the lighthouse, Thomas thought to himself, 'When the magic cores are rich in the future, I must build a luxurious Lord's Hall and build the most comfortable bed!'
Imagining the beautiful future, Thomas fell into a dream.
While he was half asleep, Thomas heard someone calling him softly.
Thomas opened his eyes and found that it was Arya squatting beside him.
"Lord, dark creatures are gathering not far away. It seems that they are going to attack the camp," Arya said softly.
"What? Dark creatures are gathering?"
Thomas heard her and sat up hurriedly.
"Let's go and take a look."
Thomas and Arya came to the watchtower of the lighthouse.
"My Liege, look! It's right there!" Arya pointed to the distance.
Thomas discovered that, 200 meters away, a group of 1.2 meters tall, red-colored monsters with two sharp horns on their heads and a thin tail behind them were gathered not far away.
They had scales on their bodies, and held old weapons in their hands. They were gathered together and whispering, constantly looking in the direction of the camp.
They looked like they wanted to attack, but they were afraid to attack.
Thomas recognized these monsters. Their name was the Lesser Demons, and they were the lowest level of dark creatures.
