The water ghost brain, the monster's claws, the monster's liver, and so on, nothing was left out, not a single corpse was missed.

Sword seemed a little curious, but after a few glances he couldn't stand it anymore and stepped back in disgust. Killing the enemy on the battlefield is one thing, but being in close contact with anatomy is another.

"What do you collect all this for?"

Geralt glanced at Sward, feeling somewhat surprised by the servant's question. "Few people would be interested in these things."

Sword replied: "The Earl seems to be interested, so I want to get familiar with it. Maybe I will do these things in the future."

Geralt snorted expressionlessly, but didn't laugh at the idea. He performed the dissection and explained, "The body materials of these monsters can all be used in alchemy, to make potions, boil sword oil, and even enchant some weapons and equipment."

The witcher groped in the flesh and blood, and suddenly his hands clenched, as if he had reaped some rewards.

Sword saw the other party pulling out a strange mass of blue flesh and blood from the water ghost's brain and said, "Found it... This kind is relatively rare, called 'blue mutant', which is more commonly used and rarer."

Mutants are somewhat like the Warcraft cores in other fantasy themes. Generally speaking, there are three types of mutants: red, blue, and green.

For demon hunters, boiling different colored mutants into potions and taking them can slightly increase the corresponding strength. Of course, this increase in strength has an upper limit, and Geralt no longer needs to take these.

Red can enhance physical strength, blue corresponds to the power of the seal, and green can enhance the demon hunter's ability to resist poison. In addition to these three more common mutants, there are also powerful monsters that produce exclusive mutants, such as werewolves, royal griffins, leopards, etc. These mutants have more unique effects.

In addition, mutants are also widely used by alchemists for other purposes. For example, the mutation trials of demon hunters cannot be carried out without the participation of these mutants.

After Geralt cleaned up all the water ghost corpses, he finally began to take off his armor with satisfaction. Then the druid cast a natural spell for all the people who were about to dive, allowing them to hold their breath underwater for a long time.

After the spell was finished, the druid reminded the human soldiers to come up and breathe every five minutes. Geralt was very familiar with this kind of magic, and his physique allowed him to stay underwater longer.

The divers jumped into the water one by one, and Lane and his team waited quietly on the shore.

"My Lord Earl!"

Suddenly a soldier surfaced and shouted excitedly, it seemed that he had gained something.

Lann stood up, looking expectant.

"I found a box with several gold necklaces and diamonds in it!"

Lann sat back down and yelled angrily, "It's not this, go down and keep looking!"

After a while, another soldier surfaced:

"My Lord Earl, I found a body underwater. He had a bag with several gems in it..."

"Not this one, get out of here and keep looking!"

After a while, a soldier surfaced.

"My Lord Earl, I seem to have found the magic-blocking gold!"

"Go away... Never mind. You should try to fish this out first. It's really a ruin. How come there are so many things here?"

Time passed by, and when the sun was setting, Geralt finally surfaced:

"I found the portal."

Lann became excited. Geralt was still reliable at the critical moment!

After hearing Geralt's news, Lann did not rush into the water. Instead, the druid beside him stood up, cast a breath-holding spell on himself, and followed Geralt into the water.

Lann on the shore called on all the soldiers to assemble, gather all the equipment, and wait quietly.

But after a few minutes, yellow sparks suddenly flashed in the air in front of everyone's eyes, and then quickly spread out. A distorted darkness stretched the sparks to the size of two people, and a howling gale blew everyone's hair everywhere.

This is the portal opened by the druid.

Lann turned around and pointed at the two sword guards, saying, "Keep an eye on Black Wind for me here, and then set up camp and wait for us to come back. If we don't come out in more than three days, call for reinforcements, understand?"

"Yes! Lord Earl!"

Lan nodded, turned around and went into the portal first. After a severe dizziness, he opened his eyes and the scenery in front of him had changed.

The divers who entered first had already lit torches all around. They could vaguely see that this was a corner of an underground ruin. There were some ancient building ruins all around. From time to time in the darkness, half of a beam with carved patterns could be seen. The walls were covered with sparse Nostrek wall grass, and the ground was covered with blood moss.

The dust on the ground was very thick. When you stepped on it, a handful of dust would fly up. It was obvious that it had been dark here for a long time.

One after another, people came out of the portal. After everyone had passed through, the druid finally breathed a sigh of relief and withdrew his magic. It seemed very difficult for him to maintain the large portal for a long time.

The divers began to put on their armor again. This was the most important significance of the druid's participation in this exploration team.

If it were a normal exploration team, they would definitely travel light in order to enter through the underwater portal, and would probably only carry small pieces of iron tools, not to mention armor.

If we encounter any powerful monster guarding the tomb with such simple equipment, we will probably be wiped out on the spot.

If a druid enters the ruins first, he can open a portal for Lann through positioning and transport fully armed soldiers in, so that he can be more confident in facing the dangers inside the ruins.

Sward took Geralt's things and handed them to him. The witcher was squatting on the ground rubbing his temples with a headache. The witcher's senses were enhanced far beyond those of ordinary people. When passing through the portal, ordinary people would only feel a brief dizziness, but the witcher was tortured.

In most cases, demon hunters would rather travel two or three days on horseback than enter a portal.

Inside the portal, Lann and his crew were packing up their equipment and officially starting their exploration.

Outside the portal, the two remaining sword guards and Black Wind were waiting.

The camp on the cliff had been dismantled and moved down, and the two men just had to slowly put it back together. It wasn't a hard job.

But Heifeng seemed a little uneasy. It neighed constantly and pawed the ground with its hooves from time to time.

Seeing this, a sword guard rushed forward to appease him, causing another person to shout in dissatisfaction: "You come to work first, why do you care about it?"

The companion replied unhappily, "Shut up, Black Wind is more valuable than the two of us combined. This is a top-notch warhorse. I heard that it was once a birthday gift from Her Majesty the Queen to Her Royal Highness the Princess, and was later gifted to the Earl."
