The instructor introduces the lesson on growing and defending a tree against pests.

• The instructor has significant experience in growing and defending trees.
• A wooden starfish-looking tree will need to be developed within seven days to resist pest attacks.
• The instructor plans to use a card-based system to enhance the tree.

Initial steps involve creating a straight stem and adding a leaf to the tree.

• A straight stem is established as the beginning of the tree's upward growth.
• At least one leaf is added to give the tree its fundamental characteristics.
• The actions of growing a stem and adding a leaf each cost one miracle, with three miracles available per day.

The instructor emphasizes the importance of managing food and growth essence for the tree.

• The tree has a starting food supply of 10, consuming one per day.
• Photosynthesis is introduced as a method to convert sun and water reserves into additional food.
• Growing stems upward generates growth essence, which allows for the placement of roots to access underground food resources.

Instructor outlines steps to reinforce the tree's defense and to further its growth.

• A Scarab is spawned to protect the tree's heart, with the ability to be placed anywhere on the stem.
• The tree's food production is increased by reaching down towards more abundant food sources.
• Leaf growth is rewarded, and the tree is prepared to weather a cloudy day with reduced sun exposure.

Strategies for tree growth and pest protection are planned out for the upcoming days.

• Further stem growth is necessary to build upward and gain more growth essence.
• The instructor contemplates the strategic placement of another Scarab for root protection.
• Concerns about the limited food in the ground drive the decision to grow additional leaves for resource absorption.

The instructor focuses on maximizing resource absorption and preparing for the pest attack.

• The tree levels up, providing a choice of rewards, and the instructor selects an ability to gain additional sun for each leaf grown.
• A cloud day affects resource production, prompting the instructor to extend the roots towards larger food deposits.
• The tree's appearance is enhanced with a flower, and preparations are made for the first fight against pests.

The instructor defends the tree against the first wave of pests using the anti-bird spray and Scarab.

• Pests attack from the sky, and the instructor deploys anti-bird spray to hit multiple pests simultaneously.
• The Scarab efficiently protects the tree by eliminating all pests within its range.
• The successful defense of the tree is considered a miracle, and the instructor reflects on the tree's current state.

The instructor continues to grow the tree while preparing for future pest waves.

• Focus shifts to creating more stems to enhance the tree's growth essence.
• Another Scarab is spawned for additional protection against ground invaders.
• The instructor considers the use of the double absorb ability and prepares for another cloudy day.

The instructor optimizes food production and pest defense with strategic growth and additional Scarabs.

• Further root extensions are made to tap into a large food deposit, greatly improving daily food gains.
• More Scarabs are spawned for defense, and a flower is added to improve the tree's aesthetics.
• The instructor successfully manages a pest wave, efficiently protecting the tree with the help of guards.

The instructor makes final preparations and sets up an ultimate defense to conclude the tree's growth.

• With a focus on food and defense, the instructor utilizes the final days to ensure the tree's survival.
• The wasp is introduced as a new defense mechanism with a large protective range.
• The tree, now mighty and well-defended, is capable of defeating even goats, proving its strength.
